configure: Make C++ test work with --enable-werror gcc's C++ compiler complains about being passed some -W options which make sense for C but not for C++. This means we mustn't try a C++ compile with QEMU_CFLAGS, but only with a filtered version that removes the offending options. This filtering was already being done for uses of C++ in the build itself, but was omitted for the "does C++ work?" configure test. This only showed up when doing builds which explicitly enabled -Werror with --enable-werror, because the "do the compilers work" tests were mistakenly placed above the "default werror based on whether compiling from git" code. Another error in this category is that clang warns if you ask it to compile C++ code from a file named "foo.c". Further, because we were running do_cc in a subshell in the condition part of an "if", the error_exit inside do_compiler wouldn't terminate configure and we would plunge on regardless. Fix this complex of errors: 1. Move the default-werror code up so that there are no invocations of compile_object and friends between it and the point where we set $werror explicitly based on the --enable-werror command line option. 2. Provide a mechanism for filtering QEMU_CFLAGS to create QEMU_CXXFLAGS, and use it for the test we run here. 3. Provide a do_cxx function to run a test with the C++ compiler rather than doing cute tricks with subshells and do_cc. 4. Use a new temporary file TMPCXX for the C++ program fragment.

i386: hvf: add code base from Google's QEMU repository This file begins tracking the files that will be the code base for HVF support in QEMU. This code base is part of Google's QEMU version of their Android emulator, and can be found at https://android.googlesource.com/platform/external/qemu/+/emu-master-dev This code is based on Veertu Inc's vdhh (Veertu Desktop Hosted Hypervisor), found at https://github.com/veertuinc/vdhh. Everything is appropriately licensed under GPL v2-or-later, except for the code inside x86_task.c and x86_task.h, which, deriving from KVM (the Linux kernel), is licensed GPL v2-only. This code base already implements a very great deal of functionality, although Google's version removed from Vertuu's the support for APIC page and hyperv-related stuff. According to the Android Emulator Release Notes, Revision 26.1.3 (August 2017), "Hypervisor.framework is now enabled by default on macOS for 32-bit x86 images to improve performance and macOS compatibility", although we better use with caution for, as the same Revision warns us, "If you experience issues with it specifically, please file a bug report...". The code hasn't seen much update in the last 5 months, so I think that we can further develop the code with occasional visiting Google's repository to see if there has been any update. On top of Google's code, the following changes were made: - add code to the configure script to support the --enable-hvf argument. If the OS is Darwin, it checks for presence of HVF in the system. The patch also adds strings related to HVF in the file qemu-options.hx. QEMU will only support the modern syntax style '-M accel=hvf' no enable hvf; the legacy '-enable-hvf' will not be supported. - fix styling issues - add glue code to cpus.c - move HVFX86EmulatorState field to CPUX86State, changing the the emulation functions to have a parameter with signature 'CPUX86State *' instead of 'CPUState *' so we don't have to get the 'env'.

Here are some boot time comparisons of the various versions of -fstack-protector using qemu-system-arm on an x86_64 host: # -fstack-protector-all Startup finished in 1.810s (kernel) + 12.331s (initrd) + 49.016s (userspace) = 1min 3.159s Startup finished in 1.801s (kernel) + 12.287s (initrd) + 47.925s (userspace) = 1min 2.013s Startup finished in 1.812s (kernel) + 12.302s (initrd) + 47.995s (userspace) = 1min 2.111s # -fstack-protector-strong Startup finished in 1.744s (kernel) + 11.223s (initrd) + 44.688s (userspace) = 57.657s Startup finished in 1.721s (kernel) + 11.222s (initrd) + 44.194s (userspace) = 57.138s Startup finished in 1.693s (kernel) + 11.250s (initrd) + 44.426s (userspace) = 57.370s # -fstack-protector Startup finished in 1.705s (kernel) + 11.409s (initrd) + 43.563s (userspace) = 56.677s Startup finished in 1.877s (kernel) + 11.137s (initrd) + 43.719s (userspace) = 56.734s Startup finished in 1.708s (kernel) + 11.141s (initrd) + 43.628s (userspace) = 56.478s # no stack protector Startup finished in 1.743s (kernel) + 11.190s (initrd) + 43.709s (userspace) = 56.643s Startup finished in 1.763s (kernel) + 11.216s (initrd) + 43.767s (userspace) = 56.747s Startup finished in 1.711s (kernel) + 11.283s (initrd) + 43.878s (userspace) = 56.873s This patch introduces a configure option to disable the stack protector entirely, and conditional stack protector flag selection (in order, based on availability): -fstack-protector-strong, -fstack-protector-all, no stack protector.

build: allow automatic git submodule updates to be disabled Some people building QEMU use VPATH builds where the source directory is on a read-only volume. In such a case 'scripts/git-submodules.sh update' will always fail and users are required to run it manually themselves on their original writable source directory. While this is already supported, it is nice to give users a command line flag to configure to permanently disable automatic submodule updates, as it means they won't get hard to diagnose failures from git-submodules.sh at an arbitrary later date. This patch thus introduces a flag '--disable-git-update' which will prevent 'make' from ever running 'scripts/git-submodules.sh update'. It will still run the 'status' command to determine if a submodule update is needed, but when it does this it'll simply stop and print a message instructing the developer what todo. eg $ ./configure --target-list=x86_64-softmmu --disable-git-update ...snip... $ make GEN config-host.h GEN trace/generated-tcg-tracers.h GEN trace/generated-helpers-wrappers.h GEN trace/generated-helpers.h GEN trace/generated-helpers.c GEN module_block.h GIT submodule checkout is out of date.

i386: hvf: add code base from Google's QEMU repository This file begins tracking the files that will be the code base for HVF support in QEMU. This code base is part of Google's QEMU version of their Android emulator, and can be found at https://android.googlesource.com/platform/external/qemu/+/emu-master-dev This code is based on Veertu Inc's vdhh (Veertu Desktop Hosted Hypervisor), found at https://github.com/veertuinc/vdhh. Everything is appropriately licensed under GPL v2-or-later, except for the code inside x86_task.c and x86_task.h, which, deriving from KVM (the Linux kernel), is licensed GPL v2-only. This code base already implements a very great deal of functionality, although Google's version removed from Vertuu's the support for APIC page and hyperv-related stuff. According to the Android Emulator Release Notes, Revision 26.1.3 (August 2017), "Hypervisor.framework is now enabled by default on macOS for 32-bit x86 images to improve performance and macOS compatibility", although we better use with caution for, as the same Revision warns us, "If you experience issues with it specifically, please file a bug report...". The code hasn't seen much update in the last 5 months, so I think that we can further develop the code with occasional visiting Google's repository to see if there has been any update. On top of Google's code, the following changes were made: - add code to the configure script to support the --enable-hvf argument. If the OS is Darwin, it checks for presence of HVF in the system. The patch also adds strings related to HVF in the file qemu-options.hx. QEMU will only support the modern syntax style '-M accel=hvf' no enable hvf; the legacy '-enable-hvf' will not be supported. - fix styling issues - add glue code to cpus.c - move HVFX86EmulatorState field to CPUX86State, changing the the emulation functions to have a parameter with signature 'CPUX86State *' instead of 'CPUState *' so we don't have to get the 'env'.

iSCSI block driver This provides built-in support for iSCSI to QEMU. This has the advantage that the iSCSI devices need not be made visible to the host, which is useful if you have very many virtual machines and very many iscsi devices. It also has the benefit that non-root users of QEMU can access iSCSI devices across the network without requiring root privilege on the host. This driver interfaces with the multiplatform posix library for iscsi initiator/client access to iscsi devices hosted at git://github.com/sahlberg/libiscsi.git The patch adds the driver to interface with the iscsi library. It also updated the configure script to * by default, probe is libiscsi is available and if so, build qemu against libiscsi. * --enable-libiscsi Force a build against libiscsi. If libiscsi is not available the build will fail. * --disable-libiscsi Do not link against libiscsi, even if it is available. When linked with libiscsi, qemu gains support to access iscsi resources such as disks and cdrom directly, without having to make the devices visible to the host. You can specify devices using a iscsi url of the form : iscsi://[<username>[:<password>@]]<host>[:<port]/<target-iqn-name>/<lun> When using authentication, the password can optionally be set with LIBISCSI_CHAP_PASSWORD="password" to avoid it showing up in the process list Signed-off-by: Ronnie Sahlberg <ronniesahlberg@gmail.com> Reviewed-by: Stefan Hajnoczi <stefanha@linux.vnet.ibm.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>

authz: add QAuthZPAM object type for authorizing using PAM Add an authorization backend that talks to PAM to check whether the user identity is allowed. This only uses the PAM account validation facility, which is essentially just a check to see if the provided username is permitted access. It doesn't use the authentication or session parts of PAM, since that's dealt with by the relevant part of QEMU (eg VNC server). Consider starting QEMU with a VNC server and telling it to use TLS with x509 client certificates and configuring it to use an PAM to validate the x509 distinguished name. In this example we're telling it to use PAM for the QAuthZ impl with a service name of "qemu-vnc" $ qemu-system-x86_64 \ -object tls-creds-x509,id=tls0,dir=/home/berrange/security/qemutls,\ endpoint=server,verify-peer=yes \ -object authz-pam,id=authz0,service=qemu-vnc \ -vnc :1,tls-creds=tls0,tls-authz=authz0 This requires an /etc/pam/qemu-vnc file to be created with the auth rules. A very simple file based whitelist can be setup using $ cat > /etc/pam/qemu-vnc <<EOF account requisite pam_listfile.so item=user sense=allow file=/etc/qemu/vnc.allow EOF The /etc/qemu/vnc.allow file simply contains one username per line. Any username not in the file is denied. The usernames in this example are the x509 distinguished name from the client's x509 cert. $ cat > /etc/qemu/vnc.allow <<EOF CN=laptop.berrange.com,O=Berrange Home,L=London,ST=London,C=GB EOF More interesting would be to configure PAM to use an LDAP backend, so that the QEMU authorization check data can be centralized instead of requiring each compute host to have file maintained. The main limitation with this PAM module is that the rules apply to all QEMU instances on the host. Setting up different rules per VM, would require creating a separate PAM service name & config file for every guest. An alternative approach for the future might be to not pass in the plain username to PAM, but instead combine the VM name or UUID with the username. This requires further consideration though.

configure: Add support for jemalloc This adds "--enable-jemalloc" and "--disable-jemalloc" to allow linking to jemalloc memory allocator. We have already tcmalloc support, but it seem to not working well with a lot of iothreads/disks. The main problem is that tcmalloc use a shared thread cache of 16MB by default. With more threads, this cache is shared, and some bad garbage collections can occur if the cache is too low. It's possible to tcmalloc cache increase it with a env var: TCMALLOC_MAX_TOTAL_THREAD_CACHE_BYTES=256MB With default 16MB, performances are really bad with more than 2 disks. Increasing to 256MB, it's helping but still have problem with 16 disks/iothreads. Jemalloc don't have performance problem with default configuration.

i386: hvf: add code base from Google's QEMU repository This file begins tracking the files that will be the code base for HVF support in QEMU. This code base is part of Google's QEMU version of their Android emulator, and can be found at https://android.googlesource.com/platform/external/qemu/+/emu-master-dev This code is based on Veertu Inc's vdhh (Veertu Desktop Hosted Hypervisor), found at https://github.com/veertuinc/vdhh. Everything is appropriately licensed under GPL v2-or-later, except for the code inside x86_task.c and x86_task.h, which, deriving from KVM (the Linux kernel), is licensed GPL v2-only. This code base already implements a very great deal of functionality, although Google's version removed from Vertuu's the support for APIC page and hyperv-related stuff. According to the Android Emulator Release Notes, Revision 26.1.3 (August 2017), "Hypervisor.framework is now enabled by default on macOS for 32-bit x86 images to improve performance and macOS compatibility", although we better use with caution for, as the same Revision warns us, "If you experience issues with it specifically, please file a bug report...". The code hasn't seen much update in the last 5 months, so I think that we can further develop the code with occasional visiting Google's repository to see if there has been any update. On top of Google's code, the following changes were made: - add code to the configure script to support the --enable-hvf argument. If the OS is Darwin, it checks for presence of HVF in the system. The patch also adds strings related to HVF in the file qemu-options.hx. QEMU will only support the modern syntax style '-M accel=hvf' no enable hvf; the legacy '-enable-hvf' will not be supported. - fix styling issues - add glue code to cpus.c - move HVFX86EmulatorState field to CPUX86State, changing the the emulation functions to have a parameter with signature 'CPUX86State *' instead of 'CPUState *' so we don't have to get the 'env'.

Add SASL authentication support ("Daniel P. Berrange") This patch adds the new SASL authentication protocol to the VNC server. It is enabled by setting the 'sasl' flag when launching VNC. SASL can optionally provide encryption via its SSF layer, if a suitable mechanism is configured (eg, GSSAPI/Kerberos, or Digest-MD5). If an SSF layer is not available, then it should be combined with the x509 VNC authentication protocol which provides encryption. eg, if using GSSAPI qemu -vnc localhost:1,sasl eg if using TLS/x509 for encryption qemu -vnc localhost:1,sasl,tls,x509 By default the Cyrus SASL library will look for its configuration in the file /etc/sasl2/qemu.conf. For non-root users, this can be overridden by setting the SASL_CONF_PATH environment variable, eg to make it look in $HOME/.sasl2. NB unprivileged users may not have access to the full range of SASL mechanisms, since some of them require some administrative privileges to configure. The patch includes an example SASL configuration file which illustrates config for GSSAPI and Digest-MD5, though it should be noted that the latter is not really considered secure any more. Most of the SASL authentication code is located in a separate source file, vnc-auth-sasl.c. The main vnc.c file only contains minimal integration glue, specifically parsing of command line flags / setup, and calls to start the SASL auth process, to do encoding/decoding for data. There are several possible stacks for reading & writing of data, depending on the combo of VNC authentication methods in use - Clear. read/write straight to socket - TLS. read/write via GNUTLS helpers - SASL. encode/decode via SASL SSF layer, then read/write to socket - SASL+TLS. encode/decode via SASL SSF layer, then read/write via GNUTLS Hence, the vnc_client_read & vnc_client_write methods have been refactored a little. vnc_client_read: main entry point for reading, calls either - vnc_client_read_plain reading, with no intermediate decoding - vnc_client_read_sasl reading, with SASL SSF decoding These two methods, then call vnc_client_read_buf(). This decides whether to write to the socket directly or write via GNUTLS. The situation is the same for writing data. More extensive comments have been added in the code / patch. The vnc_client_read_sasl and vnc_client_write_sasl method implementations live in the separate vnc-auth-sasl.c file. The state required for the SASL auth mechanism is kept in a separate VncStateSASL struct, defined in vnc-auth-sasl.h and included in the main VncState. The configure script probes for SASL and automatically enables it if found, unless --disable-vnc-sasl was given to override it.

iSCSI block driver This provides built-in support for iSCSI to QEMU. This has the advantage that the iSCSI devices need not be made visible to the host, which is useful if you have very many virtual machines and very many iscsi devices. It also has the benefit that non-root users of QEMU can access iSCSI devices across the network without requiring root privilege on the host. This driver interfaces with the multiplatform posix library for iscsi initiator/client access to iscsi devices hosted at git://github.com/sahlberg/libiscsi.git The patch adds the driver to interface with the iscsi library. It also updated the configure script to * by default, probe is libiscsi is available and if so, build qemu against libiscsi. * --enable-libiscsi Force a build against libiscsi. If libiscsi is not available the build will fail. * --disable-libiscsi Do not link against libiscsi, even if it is available. When linked with libiscsi, qemu gains support to access iscsi resources such as disks and cdrom directly, without having to make the devices visible to the host. You can specify devices using a iscsi url of the form : iscsi://[<username>[:<password>@]]<host>[:<port]/<target-iqn-name>/<lun> When using authentication, the password can optionally be set with LIBISCSI_CHAP_PASSWORD="password" to avoid it showing up in the process list Signed-off-by: Ronnie Sahlberg <ronniesahlberg@gmail.com> Reviewed-by: Stefan Hajnoczi <stefanha@linux.vnet.ibm.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>

vhost-scsi: new device supporting the tcm_vhost Linux kernel module The WWPN specified in configfs is passed to "-device vhost-scsi-pci". The tgpt field of the SET_ENDPOINT ioctl is obsolete now, so it is not available from the QEMU command-line. Instead, I hardcode it to zero. Changes in Patch-v2: - Add vhost_scsi_get_features() in order to determine feature bits supports by host kernel (mst + nab) - Re-enable usage of DEFINE_VIRTIO_COMMON_FEATURES, and allow EVENT_IDX to be disabled by host in vhost_scsi_get_features() - Drop unused hotplug bit in DEFINE_VHOST_SCSI_PROPERTIES Changes in Patch-v1: - Set event_idx=off by default (nab, thanks asias) - Disable hotplug feature bit for v3.9 tcm_vhost kernel code, need to re-enable in v3.10 (nab) - Update to latest qemu.git/master HEAD Changes in WIP-V3: - Drop ioeventfd vhost_scsi_properties (asias, thanks stefanha) - Add CONFIG_VHOST_SCSI (asias, thanks stefanha) - Add hotplug feature bit Changes in WIP-V2: - Add backend guest masking support (nab) - Bump ABI_VERSION to 1 (nab) - Set up set_guest_notifiers (asias) - Set up vs->dev.vq_index (asias) - Drop vs->vs.vdev.{set,clear}_vhost_endpoint (asias) - Drop VIRTIO_CONFIG_S_DRIVER check in vhost_scsi_set_status (asias) Howto: Use the latest seabios, at least commit b44a7be17b git clone git://git.seabios.org/seabios.git make cp out/bios.bin /usr/share/qemu/bios.bin qemu -device vhost-scsi-pci,wwpn=naa.6001405bd4e8476d,event_idx=off ...

authz: add QAuthZPAM object type for authorizing using PAM Add an authorization backend that talks to PAM to check whether the user identity is allowed. This only uses the PAM account validation facility, which is essentially just a check to see if the provided username is permitted access. It doesn't use the authentication or session parts of PAM, since that's dealt with by the relevant part of QEMU (eg VNC server). Consider starting QEMU with a VNC server and telling it to use TLS with x509 client certificates and configuring it to use an PAM to validate the x509 distinguished name. In this example we're telling it to use PAM for the QAuthZ impl with a service name of "qemu-vnc" $ qemu-system-x86_64 \ -object tls-creds-x509,id=tls0,dir=/home/berrange/security/qemutls,\ endpoint=server,verify-peer=yes \ -object authz-pam,id=authz0,service=qemu-vnc \ -vnc :1,tls-creds=tls0,tls-authz=authz0 This requires an /etc/pam/qemu-vnc file to be created with the auth rules. A very simple file based whitelist can be setup using $ cat > /etc/pam/qemu-vnc <<EOF account requisite pam_listfile.so item=user sense=allow file=/etc/qemu/vnc.allow EOF The /etc/qemu/vnc.allow file simply contains one username per line. Any username not in the file is denied. The usernames in this example are the x509 distinguished name from the client's x509 cert. $ cat > /etc/qemu/vnc.allow <<EOF CN=laptop.berrange.com,O=Berrange Home,L=London,ST=London,C=GB EOF More interesting would be to configure PAM to use an LDAP backend, so that the QEMU authorization check data can be centralized instead of requiring each compute host to have file maintained. The main limitation with this PAM module is that the rules apply to all QEMU instances on the host. Setting up different rules per VM, would require creating a separate PAM service name & config file for every guest. An alternative approach for the future might be to not pass in the plain username to PAM, but instead combine the VM name or UUID with the username. This requires further consideration though.

configure: Add support for jemalloc This adds "--enable-jemalloc" and "--disable-jemalloc" to allow linking to jemalloc memory allocator. We have already tcmalloc support, but it seem to not working well with a lot of iothreads/disks. The main problem is that tcmalloc use a shared thread cache of 16MB by default. With more threads, this cache is shared, and some bad garbage collections can occur if the cache is too low. It's possible to tcmalloc cache increase it with a env var: TCMALLOC_MAX_TOTAL_THREAD_CACHE_BYTES=256MB With default 16MB, performances are really bad with more than 2 disks. Increasing to 256MB, it's helping but still have problem with 16 disks/iothreads. Jemalloc don't have performance problem with default configuration.

build: allow automatic git submodule updates to be disabled Some people building QEMU use VPATH builds where the source directory is on a read-only volume. In such a case 'scripts/git-submodules.sh update' will always fail and users are required to run it manually themselves on their original writable source directory. While this is already supported, it is nice to give users a command line flag to configure to permanently disable automatic submodule updates, as it means they won't get hard to diagnose failures from git-submodules.sh at an arbitrary later date. This patch thus introduces a flag '--disable-git-update' which will prevent 'make' from ever running 'scripts/git-submodules.sh update'. It will still run the 'status' command to determine if a submodule update is needed, but when it does this it'll simply stop and print a message instructing the developer what todo. eg $ ./configure --target-list=x86_64-softmmu --disable-git-update ...snip... $ make GEN config-host.h GEN trace/generated-tcg-tracers.h GEN trace/generated-helpers-wrappers.h GEN trace/generated-helpers.h GEN trace/generated-helpers.c GEN module_block.h GIT submodule checkout is out of date.

authz: add QAuthZPAM object type for authorizing using PAM Add an authorization backend that talks to PAM to check whether the user identity is allowed. This only uses the PAM account validation facility, which is essentially just a check to see if the provided username is permitted access. It doesn't use the authentication or session parts of PAM, since that's dealt with by the relevant part of QEMU (eg VNC server). Consider starting QEMU with a VNC server and telling it to use TLS with x509 client certificates and configuring it to use an PAM to validate the x509 distinguished name. In this example we're telling it to use PAM for the QAuthZ impl with a service name of "qemu-vnc" $ qemu-system-x86_64 \ -object tls-creds-x509,id=tls0,dir=/home/berrange/security/qemutls,\ endpoint=server,verify-peer=yes \ -object authz-pam,id=authz0,service=qemu-vnc \ -vnc :1,tls-creds=tls0,tls-authz=authz0 This requires an /etc/pam/qemu-vnc file to be created with the auth rules. A very simple file based whitelist can be setup using $ cat > /etc/pam/qemu-vnc <<EOF account requisite pam_listfile.so item=user sense=allow file=/etc/qemu/vnc.allow EOF The /etc/qemu/vnc.allow file simply contains one username per line. Any username not in the file is denied. The usernames in this example are the x509 distinguished name from the client's x509 cert. $ cat > /etc/qemu/vnc.allow <<EOF CN=laptop.berrange.com,O=Berrange Home,L=London,ST=London,C=GB EOF More interesting would be to configure PAM to use an LDAP backend, so that the QEMU authorization check data can be centralized instead of requiring each compute host to have file maintained. The main limitation with this PAM module is that the rules apply to all QEMU instances on the host. Setting up different rules per VM, would require creating a separate PAM service name & config file for every guest. An alternative approach for the future might be to not pass in the plain username to PAM, but instead combine the VM name or UUID with the username. This requires further consideration though.

i386: hvf: add code base from Google's QEMU repository This file begins tracking the files that will be the code base for HVF support in QEMU. This code base is part of Google's QEMU version of their Android emulator, and can be found at https://android.googlesource.com/platform/external/qemu/+/emu-master-dev This code is based on Veertu Inc's vdhh (Veertu Desktop Hosted Hypervisor), found at https://github.com/veertuinc/vdhh. Everything is appropriately licensed under GPL v2-or-later, except for the code inside x86_task.c and x86_task.h, which, deriving from KVM (the Linux kernel), is licensed GPL v2-only. This code base already implements a very great deal of functionality, although Google's version removed from Vertuu's the support for APIC page and hyperv-related stuff. According to the Android Emulator Release Notes, Revision 26.1.3 (August 2017), "Hypervisor.framework is now enabled by default on macOS for 32-bit x86 images to improve performance and macOS compatibility", although we better use with caution for, as the same Revision warns us, "If you experience issues with it specifically, please file a bug report...". The code hasn't seen much update in the last 5 months, so I think that we can further develop the code with occasional visiting Google's repository to see if there has been any update. On top of Google's code, the following changes were made: - add code to the configure script to support the --enable-hvf argument. If the OS is Darwin, it checks for presence of HVF in the system. The patch also adds strings related to HVF in the file qemu-options.hx. QEMU will only support the modern syntax style '-M accel=hvf' no enable hvf; the legacy '-enable-hvf' will not be supported. - fix styling issues - add glue code to cpus.c - move HVFX86EmulatorState field to CPUX86State, changing the the emulation functions to have a parameter with signature 'CPUX86State *' instead of 'CPUState *' so we don't have to get the 'env'.

configure: Add support for jemalloc This adds "--enable-jemalloc" and "--disable-jemalloc" to allow linking to jemalloc memory allocator. We have already tcmalloc support, but it seem to not working well with a lot of iothreads/disks. The main problem is that tcmalloc use a shared thread cache of 16MB by default. With more threads, this cache is shared, and some bad garbage collections can occur if the cache is too low. It's possible to tcmalloc cache increase it with a env var: TCMALLOC_MAX_TOTAL_THREAD_CACHE_BYTES=256MB With default 16MB, performances are really bad with more than 2 disks. Increasing to 256MB, it's helping but still have problem with 16 disks/iothreads. Jemalloc don't have performance problem with default configuration.

configure: Make C++ test work with --enable-werror gcc's C++ compiler complains about being passed some -W options which make sense for C but not for C++. This means we mustn't try a C++ compile with QEMU_CFLAGS, but only with a filtered version that removes the offending options. This filtering was already being done for uses of C++ in the build itself, but was omitted for the "does C++ work?" configure test. This only showed up when doing builds which explicitly enabled -Werror with --enable-werror, because the "do the compilers work" tests were mistakenly placed above the "default werror based on whether compiling from git" code. Another error in this category is that clang warns if you ask it to compile C++ code from a file named "foo.c". Further, because we were running do_cc in a subshell in the condition part of an "if", the error_exit inside do_compiler wouldn't terminate configure and we would plunge on regardless. Fix this complex of errors: 1. Move the default-werror code up so that there are no invocations of compile_object and friends between it and the point where we set $werror explicitly based on the --enable-werror command line option. 2. Provide a mechanism for filtering QEMU_CFLAGS to create QEMU_CXXFLAGS, and use it for the test we run here. 3. Provide a do_cxx function to run a test with the C++ compiler rather than doing cute tricks with subshells and do_cc. 4. Use a new temporary file TMPCXX for the C++ program fragment.

oslib-win32: only provide localtime_r/gmtime_r if missing The oslib-win32 file currently provides a localtime_r and gmtime_r replacement unconditionally. Some versions of Mingw-w64 would provide crude macros for localtime_r/gmtime_r which QEMU takes care to disable. Latest versions of Mingw-w64 now provide actual functions for localtime_r/gmtime_r, but with a twist that you have to include unistd.h or pthread.h before including time.h. By luck some files in QEMU have such an include order, resulting in compile errors: CC util/osdep.o In file included from include/qemu-common.h:48:0, from util/osdep.c:48: include/sysemu/os-win32.h:77:12: error: redundant redeclaration of 'gmtime_r' [-Werror=redundant-decls] struct tm *gmtime_r(const time_t *timep, struct tm *result); ^ In file included from include/qemu-common.h:35:0, from util/osdep.c:48: /usr/i686-w64-mingw32/sys-root/mingw/include/time.h:272:107: note: previous definition of 'gmtime_r' was here In file included from include/qemu-common.h:48:0, from util/osdep.c:48: include/sysemu/os-win32.h:79:12: error: redundant redeclaration of 'localtime_r' [-Werror=redundant-decls] struct tm *localtime_r(const time_t *timep, struct tm *result); ^ In file included from include/qemu-common.h:35:0, from util/osdep.c:48: /usr/i686-w64-mingw32/sys-root/mingw/include/time.h:269:107: note: previous definition of 'localtime_r' was here This change adds a configure test to see if localtime_r exits, and only enables the QEMU impl if missing. We also re-arrange qemu-common.h try attempt to guarantee that all source files get unistd.h before time.h and thus see the localtime_r/gmtime_r defs.

authz: add QAuthZPAM object type for authorizing using PAM Add an authorization backend that talks to PAM to check whether the user identity is allowed. This only uses the PAM account validation facility, which is essentially just a check to see if the provided username is permitted access. It doesn't use the authentication or session parts of PAM, since that's dealt with by the relevant part of QEMU (eg VNC server). Consider starting QEMU with a VNC server and telling it to use TLS with x509 client certificates and configuring it to use an PAM to validate the x509 distinguished name. In this example we're telling it to use PAM for the QAuthZ impl with a service name of "qemu-vnc" $ qemu-system-x86_64 \ -object tls-creds-x509,id=tls0,dir=/home/berrange/security/qemutls,\ endpoint=server,verify-peer=yes \ -object authz-pam,id=authz0,service=qemu-vnc \ -vnc :1,tls-creds=tls0,tls-authz=authz0 This requires an /etc/pam/qemu-vnc file to be created with the auth rules. A very simple file based whitelist can be setup using $ cat > /etc/pam/qemu-vnc <<EOF account requisite pam_listfile.so item=user sense=allow file=/etc/qemu/vnc.allow EOF The /etc/qemu/vnc.allow file simply contains one username per line. Any username not in the file is denied. The usernames in this example are the x509 distinguished name from the client's x509 cert. $ cat > /etc/qemu/vnc.allow <<EOF CN=laptop.berrange.com,O=Berrange Home,L=London,ST=London,C=GB EOF More interesting would be to configure PAM to use an LDAP backend, so that the QEMU authorization check data can be centralized instead of requiring each compute host to have file maintained. The main limitation with this PAM module is that the rules apply to all QEMU instances on the host. Setting up different rules per VM, would require creating a separate PAM service name & config file for every guest. An alternative approach for the future might be to not pass in the plain username to PAM, but instead combine the VM name or UUID with the username. This requires further consideration though.

Add SASL authentication support ("Daniel P. Berrange") This patch adds the new SASL authentication protocol to the VNC server. It is enabled by setting the 'sasl' flag when launching VNC. SASL can optionally provide encryption via its SSF layer, if a suitable mechanism is configured (eg, GSSAPI/Kerberos, or Digest-MD5). If an SSF layer is not available, then it should be combined with the x509 VNC authentication protocol which provides encryption. eg, if using GSSAPI qemu -vnc localhost:1,sasl eg if using TLS/x509 for encryption qemu -vnc localhost:1,sasl,tls,x509 By default the Cyrus SASL library will look for its configuration in the file /etc/sasl2/qemu.conf. For non-root users, this can be overridden by setting the SASL_CONF_PATH environment variable, eg to make it look in $HOME/.sasl2. NB unprivileged users may not have access to the full range of SASL mechanisms, since some of them require some administrative privileges to configure. The patch includes an example SASL configuration file which illustrates config for GSSAPI and Digest-MD5, though it should be noted that the latter is not really considered secure any more.

Add SASL authentication support ("Daniel P. Berrange") This patch adds the new SASL authentication protocol to the VNC server. It is enabled by setting the 'sasl' flag when launching VNC. SASL can optionally provide encryption via its SSF layer, if a suitable mechanism is configured (eg, GSSAPI/Kerberos, or Digest-MD5). If an SSF layer is not available, then it should be combined with the x509 VNC authentication protocol which provides encryption. eg, if using GSSAPI qemu -vnc localhost:1,sasl eg if using TLS/x509 for encryption qemu -vnc localhost:1,sasl,tls,x509 By default the Cyrus SASL library will look for its configuration in the file /etc/sasl2/qemu.conf. For non-root users, this can be overridden by setting the SASL_CONF_PATH environment variable, eg to make it look in $HOME/.sasl2. NB unprivileged users may not have access to the full range of SASL mechanisms, since some of them require some administrative privileges to configure. The patch includes an example SASL configuration file which illustrates config for GSSAPI and Digest-MD5, though it should be noted that the latter is not really considered secure any more.

Support ACLs for controlling VNC access ("Daniel P. Berrange") This patch introduces a generic internal API for access control lists to be used by network servers in QEMU. It adds support for checking these ACL in the VNC server, in two places. The first ACL is for the SASL authentication mechanism, checking the SASL username. This ACL is called 'vnc.username'. The second is for the TLS authentication mechanism, when x509 client certificates are turned on, checking against the Distinguished Name of the client. This ACL is called 'vnc.x509dname' The internal API provides for an ACL with the following characteristics - A unique name, eg vnc.username, and vnc.x509dname. - A default policy, allow or deny - An ordered series of match rules, with allow or deny policy If none of the match rules apply, then the default policy is used. There is a monitor API to manipulate the ACLs, which I'll describe via examples (qemu) acl show vnc.username policy: allow (qemu) acl policy vnc.username denya acl: policy set to 'deny' (qemu) acl allow vnc.username fred acl: added rule at position 1 (qemu) acl allow vnc.username bob acl: added rule at position 2 (qemu) acl allow vnc.username joe 1 acl: added rule at position 1 (qemu) acl show vnc.username policy: deny 0: allow fred 1: allow joe 2: allow bob (qemu) acl show vnc.x509dname policy: allow (qemu) acl policy vnc.x509dname deny acl: policy set to 'deny' (qemu) acl allow vnc.x509dname C=GB,O=ACME,L=London,CN=* acl: added rule at position 1 (qemu) acl allow vnc.x509dname C=GB,O=ACME,L=Boston,CN=bob acl: added rule at position 2 (qemu) acl show vnc.x509dname policy: deny 0: allow C=GB,O=ACME,L=London,CN=* 1: allow C=GB,O=ACME,L=Boston,CN=bob By default the VNC server will not use any ACLs, allowing access to the server if the user successfully authenticates. To enable use of ACLs to restrict user access, the ',acl' flag should be given when starting QEMU. The initial ACL activated will be a 'deny all' policy and should be customized using monitor commands. eg enable SASL auth and ACLs qemu .... -vnc localhost:1,sasl,acl The next patch will provide a way to load a pre-defined ACL when starting up Makefile | 6 + b/acl.c | 185 ++++++++++++++++++++++++++++++++++++++++++++++++++++++++ b/acl.h | 74 ++++++++++++++++++++++ configure | 18 +++++ monitor.c | 95 ++++++++++++++++++++++++++++ qemu-doc.texi | 49 ++++++++++++++ vnc-auth-sasl.c | 16 +++- vnc-auth-sasl.h | 7 ++ vnc-tls.c | 19 +++++ vnc-tls.h | 3 vnc.c | 21 ++++++ vnc.h | 3 12 files changed, 491 insertions(+), 5 deletions(-) Signed-off-by: Daniel P.

tests: introduce a framework for testing migration performance This introduces a moderately general purpose framework for testing performance of migration. The initial guest workload is provided by the included 'stress' program, which is configured to spawn one thread per guest CPU and run a maximally memory intensive workload. It will loop over GB of memory, xor'ing each byte with data from a 4k array of random bytes. This ensures heavy read and write load across all of guest memory to stress the migration performance. While running the 'stress' program will record how long it takes to xor each GB of memory and print this data for later reporting. The test engine will spawn a pair of QEMU processes, either on the same host, or with the target on a remote host via ssh, using the host kernel and a custom initrd built with 'stress' as the /init binary. Kernel command line args are set to ensure a fast kernel boot time (< 1 second) between launching QEMU and the stress program starting execution. None the less, the test engine will initially wait N seconds for the guest workload to stablize, before starting the migration operation. When migration is running, the engine will use pause, post-copy, autoconverge, xbzrle compression and multithread compression features, as well as downtime & bandwidth tuning to encourage completion. If migration completes, the test engine will wait N seconds again for the guest workooad to stablize on the target host. If migration does not complete after a preset number of iterations, it will be aborted. While the QEMU process is running on the source host, the test engine will sample the host CPU usage of QEMU as a whole, and each vCPU thread. While migration is running, it will record all the stats reported by 'query-migration'. Finally, it will capture the output of the stress program running in the guest. All the data produced from a single test execution is recorded in a structured JSON file. A separate program is then able to create interactive charts using the "plotly" python + javascript libraries, showing the characteristics of the migration. The data output provides visualization of the effect on guest vCPU workloads from the migration process, the corresponding vCPU utilization on the host, and the overall CPU hit from QEMU on the host. This is correlated from statistics from the migration process, such as downtime, vCPU throttling and iteration number. While the tests can be run individually with arbitrary parameters, there is also a facility for producing batch reports for a number of pre-defined scenarios / comparisons, in order to be able to get standardized results across different hardware configurations (eg TCP vs RDMA, or comparing different VCPU counts / memory sizes, etc). To use this, first you must build the initrd image $ make tests/migration/initrd-stress.img To run a a one-shot test with all default parameters $ ./tests/migration/guestperf.py > result.json This has many command line args for varying its behaviour. For example, to increase the RAM size and CPU count and bind it to specific host NUMA nodes $ ./tests/migration/guestperf.py \ --mem 4 --cpus 2 \ --src-mem-bind 0 --src-cpu-bind 0,1 \ --dst-mem-bind 1 --dst-cpu-bind 2,3 \ > result.json Using mem + cpu binding is strongly recommended on NUMA machines, otherwise the guest performance results will vary wildly between runs of the test due to lucky/unlucky NUMA placement, making sensible data analysis impossible. To make it run across separate hosts: $ ./tests/migration/guestperf.py \ --dst-host somehostname > result.json To request that post-copy is enabled, with switchover after 5 iterations $ ./tests/migration/guestperf.py \ --post-copy --post-copy-iters 5 > result.json Once a result.json file is created, a graph of the data can be generated, showing guest workload performance per thread and the migration iteration points: $ ./tests/migration/guestperf-plot.py --output result.html \ --migration-iters --split-guest-cpu result.json To further include host vCPU utilization and overall QEMU utilization $ ./tests/migration/guestperf-plot.py --output result.html \ --migration-iters --split-guest-cpu \ --qemu-cpu --vcpu-cpu result.json NB, the 'guestperf-plot.py' command requires that you have the plotly python library installed. eg you must do $ pip install --user plotly Viewing the result.html file requires that you have the plotly.min.js file in the same directory as the HTML output. This js file is installed as part of the plotly python library, so can be found in $HOME/.local/lib/python2.7/site-packages/plotly/offline/plotly.min.js The guestperf-plot.py program can accept multiple json files to plot, enabling results from different configurations to be compared. Finally, to run the entire standardized set of comparisons $ ./tests/migration/guestperf-batch.py \ --dst-host somehost \ --mem 4 --cpus 2 \ --src-mem-bind 0 --src-cpu-bind 0,1 \ --dst-mem-bind 1 --dst-cpu-bind 2,3 --output tcp-somehost-4gb-2cpu will store JSON files from all scenarios in the directory named tcp-somehost-4gb-2cpu Signed-off-by: Daniel P.

qemu-io: Add generic function for reinitializing optind. On FreeBSD 11.2: $ nbdkit memory size=1M --run './qemu-io -f raw -c "aio_write 0 512" $nbd' Parsing error: non-numeric argument, or extraneous/unrecognized suffix -- aio_write After main option parsing, we reinitialize optind so we can parse each command. However reinitializing optind to 0 does not work on FreeBSD. What happens when you do this is optind remains 0 after the option parsing loop, and the result is we try to parse argv[optind] == argv[0] == "aio_write" as if it was the first parameter. The FreeBSD manual page says: In order to use getopt() to evaluate multiple sets of arguments, or to evaluate a single set of arguments multiple times, the variable optreset must be set to 1 before the second and each additional set of calls to getopt(), and the variable optind must be reinitialized. (From the rest of the man page it is clear that optind must be reinitialized to 1). The glibc man page says: A program that scans multiple argument vectors, or rescans the same vector more than once, and wants to make use of GNU extensions such as '+' and '-' at the start of optstring, or changes the value of POSIXLY_CORRECT between scans, must reinitialize getopt() by resetting optind to 0, rather than the traditional value of 1. (Resetting to 0 forces the invocation of an internal initialization routine that rechecks POSIXLY_CORRECT and checks for GNU extensions in optstring.) This commit introduces an OS-portability function called qemu_reset_optind which provides a way of resetting optind that works on FreeBSD and platforms that use optreset, while keeping it the same as now on other platforms. Note that the qemu codebase sets optind in many other places, but in those other places it's setting a local variable and not using getopt. This change is only needed in places where we are using getopt and the associated global variable optind. Signed-off-by: Richard W.M.

You can specify devices using a iscsi url of the form : iscsi://[<username>[:<password>@]]<host>[:<port]/<target-iqn-name>/<lun> When using authentication, the password can optionally be set with LIBISCSI_CHAP_PASSWORD="password" to avoid it showing up in the process list Signed-off-by: Ronnie Sahlberg <ronniesahlberg@gmail.com> Reviewed-by: Stefan Hajnoczi <stefanha@linux.vnet.ibm.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>

configure: mark qemu-ga VSS includes as system headers As of e4650c81, we do w32 builds with -Werror enabled. Unfortunately for cases where we enable VSS support in qemu-ga, we still have warnings generated by VSS includes that ship as part of the Microsoft VSS SDK. We can selectively address a number of these warnings using #pragma GCC diagnostic ignored ... but at least one of these: warning: ‘typedef’ was ignored in this declaration resulting from declarations of the form: typedef struct Blah { ... }; does not provide a specific command-line/pragma option to disable warnings of the sort. To allow VSS builds to succeed, the next-best option is disabling these warnings on a per-file basis. pragmas like #pragma GCC system_header can be used to declare subsequent includes/declarations as being exempt from normal warnings, but this must be done within a header file. Since we don't control the VSS SDK, we'd need to rely on a intermediate header include to accomplish this, and since different objects in the VSS link target rely on different headers from the VSS SDK, this would become somewhat of a rat's nest (though not totally unmanageable). The next step up in granularity is just marking the entire VSS SDK include path as system headers via -isystem. This is a bit more heavy-handed, but since this SDK hasn't changed since 2005, there's likely little to be gained from selectively disabling warnings anyway, so we implement that approach here. This fixes the -Werror failures in both the configure test and the qga build due to shared reliance on $vss_win32_include. For the same reason, this also enforces a new dependency on -isystem support in the C/C++ compiler when building QGA with VSS enabled.

Add a DTrace tracing backend targetted for SystemTAP compatability This introduces a new tracing backend that targets the SystemTAP implementation of DTrace userspace tracing. The core functionality should be applicable and standard across any DTrace implementation on Solaris, OS-X, *BSD, but the Makefile rules will likely need some small additional changes to cope with OS specific build requirements. This backend builds a little differently from the other tracing backends. Specifically there is no 'trace.c' file, because the 'dtrace' command line tool generates a '.o' file directly from the dtrace probe definition file. The probe definition is usually named with a '.d' extension but QEMU uses '.d' files for its external makefile dependancy tracking, so this uses '.dtrace' as the extension for the probe definition file. The 'tracetool' program gains the ability to generate a trace.h file for DTrace, and also to generate the trace.d file containing the dtrace probe definition. Example usage of a dtrace probe in systemtap looks like: probe process("qemu").mark("qemu_malloc") { printf("Malloc %d %p\n", $arg1, $arg2); } * .gitignore: Ignore trace-dtrace.* * Makefile: Extra rules for generating DTrace files * Makefile.obj: Don't build trace.o for DTrace, use trace-dtrace.o generated by 'dtrace' instead * tracetool: Support for generating DTrace data files Reviewed-by: Stefan Hajnoczi <stefanha@linux.vnet.ibm.com> Signed-off-by: Daniel P.

i386: hvf: add code base from Google's QEMU repository This file begins tracking the files that will be the code base for HVF support in QEMU. This code base is part of Google's QEMU version of their Android emulator, and can be found at https://android.googlesource.com/platform/external/qemu/+/emu-master-dev This code is based on Veertu Inc's vdhh (Veertu Desktop Hosted Hypervisor), found at https://github.com/veertuinc/vdhh. Everything is appropriately licensed under GPL v2-or-later, except for the code inside x86_task.c and x86_task.h, which, deriving from KVM (the Linux kernel), is licensed GPL v2-only. This code base already implements a very great deal of functionality, although Google's version removed from Vertuu's the support for APIC page and hyperv-related stuff. According to the Android Emulator Release Notes, Revision 26.1.3 (August 2017), "Hypervisor.framework is now enabled by default on macOS for 32-bit x86 images to improve performance and macOS compatibility", although we better use with caution for, as the same Revision warns us, "If you experience issues with it specifically, please file a bug report...". The code hasn't seen much update in the last 5 months, so I think that we can further develop the code with occasional visiting Google's repository to see if there has been any update. On top of Google's code, the following changes were made: - add code to the configure script to support the --enable-hvf argument. If the OS is Darwin, it checks for presence of HVF in the system. The patch also adds strings related to HVF in the file qemu-options.hx. QEMU will only support the modern syntax style '-M accel=hvf' no enable hvf; the legacy '-enable-hvf' will not be supported. - fix styling issues - add glue code to cpus.c - move HVFX86EmulatorState field to CPUX86State, changing the the emulation functions to have a parameter with signature 'CPUX86State *' instead of 'CPUState *' so we don't have to get the 'env'.

use _Static_assert in QEMU_BUILD_BUG_ON QEMU_BUILD_BUG_ON should use C11's _Static_assert, if the compiler supports it, to provide more readable messages on failure. We check for _Static_assert in configure, and set CONFIG_STATIC_ASSERT accordingly. QEMU_BUILD_BUG_ON invokes _Static_assert if CONFIG_STATIC_ASSERT is defined, and reverts to the old way otherwise. That way, systems without C11 conforming compiler will still have the old messages, as verified by intentionally breaking the configure check. the following example output was generated by inverting the condition in QEMU_BUILD_BUG_ON: without _Static_assert: > In file included from /qemu/include/qemu/osdep.h:36:0, > from /qemu/qga/commands.c:13: > /qemu/qga/commands.c: In function ‘qmp_guest_exec_status’: > /qemu/include/qemu/compiler.h:89:12: error: negative width in bit-field ‘<anonymous>’ > struct { \ > ^ > /qemu/include/qemu/compiler.h:96:38: note: in expansion of macro QEMU_BUILD_BUG_ON_STRUCT’ > #define QEMU_BUILD_BUG_ON(x) typedef QEMU_BUILD_BUG_ON_STRUCT(x) \ > ^~~~~~~~~~~~~~~~~~~~~~~~ > /qemu/include/qemu/atomic.h:146:5: note: in expansion of macro ‘QEMU_BUILD_BUG_ON’ > QEMU_BUILD_BUG_ON(sizeof(*ptr) > sizeof(void *)); \ > ^~~~~~~~~~~~~~~~~ > /qemu/include/qemu/atomic.h:417:5: note: in expansion of macro ‘atomic_load_acquire’ > atomic_load_acquire(ptr) > ^~~~~~~~~~~~~~~~~~~ > /qemu/qga/commands.c:160:21: note: in expansion of macro ‘atomic_mb_read’ > bool finished = atomic_mb_read(&gei->finished); > ^~~~~~~~~~~~~~ with _Static_assert: > In file included from /qemu/include/qemu/osdep.h:36:0, > from /qemu/qga/commands.c:13: > /qemu/qga/commands.c: In function ‘qmp_guest_exec_status’: > /qemu/include/qemu/compiler.h:94:30: error: static assertion failed: "not expecting: sizeof(*&gei->finished) > sizeof(void *)" > #define QEMU_BUILD_BUG_ON(x) _Static_assert((x), #x) > ^ > /qemu/include/qemu/atomic.h:146:5: note: in expansion of macro ‘QEMU_BUILD_BUG_ON’ > QEMU_BUILD_BUG_ON(sizeof(*ptr) > sizeof(void *)); \ > ^~~~~~~~~~~~~~~~~ > /qemu/include/qemu/atomic.h:417:5: note: in expansion of macro ‘atomic_load_acquire’ > atomic_load_acquire(ptr) > ^~~~~~~~~~~~~~~~~~~ > /qemu/qga/commands.c:160:21: note: in expansion of macro ‘atomic_mb_read’ > bool finished = atomic_mb_read(&gei->finished); > ^~~~~~~~~~~~~~ Signed-off-by: Andreas Grapentin <andreas@grapentin.org> Message-Id: <20170314165953.18506-1-andreas@grapentin.org> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

qemu-ga: Add Windows VSS provider and requester as DLL Adds VSS provider and requester as a qga-vss.dll, which is loaded by Windows VSS service as well as by qemu-ga. "provider.cpp" implements a basic stub of a software VSS provider. Currently, this module only relays a frozen event from VSS service to the agent, and thaw event from the agent to VSS service, to block VSS process to keep the system frozen while snapshots are taken at the host. To register the provider to the guest system as COM+ application, the type library (.tlb) for qga-vss.dll is required. To build it from COM IDL (.idl), VisualC++, MIDL and stdole2.tlb in Windows SDK are required. This patch also adds pre-compiled .tlb file in the repository in order to enable cross-compile qemu-ga.exe for Windows with VSS support. "requester.cpp" provides the VSS requester to kick the VSS snapshot process. Qemu-ga.exe works without the DLL, although fsfreeze features are disabled. These functions are only supported in Windows 2003 or later. In older systems, fsfreeze features are disabled. In several versions of Windows which don't support attribute VSS_VOLSNAP_ATTR_NO_AUTORECOVERY, DoSnapshotSet fails with error VSS_E_OBJECT_NOT_FOUND. In this patch, we just ignore this error. To solve this fundamentally, we need a framework to handle mount writable snapshot on guests, which is required by VSS auto-recovery feature (cleanup phase after a snapshot is taken).

build: qemu-ga: add 'qemu-ga' build target for w32 Currently POSIX builds rely on 'qemu-ga' target to do qga-only distributable build. On w32, as with most standalone binary targets, we rely on 'qemu-ga.exe' target. Unlike with POSIX, qemu-ga for w32 has a number of related targets such as VSS DLL and MSI package. We can do the full distributable qga-only build on w32 with: make qemu-ga.exe or: make msi To make that work, we tie VSS dependencies onto qemu-ga.exe. However, in reality the DLL isn't part of the binary, so we use a filter to pull them out of the LINK recipe, which attempts to link against prereqs for binary targets. Additionally, it could be argued that VSS is a separate distributable, and shouldn't be implied by qemu-ga.exe binary target. To avoid this, we can tie the VSS dependencies only to the 'msi' target, but that would make it impossible to do a qga-only build of the w32 distributable without building the 'msi' package, which was supported in the past. An alternative approach is to add a new target to build the whole distributable. w32 allows us to use the same build target we use on POSIX, 'qemu-ga', since the current binary-only target on w32 is 'qemu-ga.exe'. To further simplify the build, we also make 'qemu-ga' build the MSI package if the appropriate ./configure options are set, making the full qga-only build the same on both POSIX and w32: `make qemu-ga` Cc: Paolo Bonzini <pbonzini@redhat.com> Cc: Marc-André Lureau <marcandre.lureau@redhat.com> Signed-off-by: Michael Roth <mdroth@linux.vnet.ibm.com>

authz: add QAuthZPAM object type for authorizing using PAM Add an authorization backend that talks to PAM to check whether the user identity is allowed. This only uses the PAM account validation facility, which is essentially just a check to see if the provided username is permitted access. It doesn't use the authentication or session parts of PAM, since that's dealt with by the relevant part of QEMU (eg VNC server). Consider starting QEMU with a VNC server and telling it to use TLS with x509 client certificates and configuring it to use an PAM to validate the x509 distinguished name. In this example we're telling it to use PAM for the QAuthZ impl with a service name of "qemu-vnc" $ qemu-system-x86_64 \ -object tls-creds-x509,id=tls0,dir=/home/berrange/security/qemutls,\ endpoint=server,verify-peer=yes \ -object authz-pam,id=authz0,service=qemu-vnc \ -vnc :1,tls-creds=tls0,tls-authz=authz0 This requires an /etc/pam/qemu-vnc file to be created with the auth rules. A very simple file based whitelist can be setup using $ cat > /etc/pam/qemu-vnc <<EOF account requisite pam_listfile.so item=user sense=allow file=/etc/qemu/vnc.allow EOF The /etc/qemu/vnc.allow file simply contains one username per line. Any username not in the file is denied. The usernames in this example are the x509 distinguished name from the client's x509 cert. $ cat > /etc/qemu/vnc.allow <<EOF CN=laptop.berrange.com,O=Berrange Home,L=London,ST=London,C=GB EOF More interesting would be to configure PAM to use an LDAP backend, so that the QEMU authorization check data can be centralized instead of requiring each compute host to have file maintained. The main limitation with this PAM module is that the rules apply to all QEMU instances on the host. Setting up different rules per VM, would require creating a separate PAM service name & config file for every guest. An alternative approach for the future might be to not pass in the plain username to PAM, but instead combine the VM name or UUID with the username. This requires further consideration though.

i386: hvf: add code base from Google's QEMU repository This file begins tracking the files that will be the code base for HVF support in QEMU. This code base is part of Google's QEMU version of their Android emulator, and can be found at https://android.googlesource.com/platform/external/qemu/+/emu-master-dev This code is based on Veertu Inc's vdhh (Veertu Desktop Hosted Hypervisor), found at https://github.com/veertuinc/vdhh. Everything is appropriately licensed under GPL v2-or-later, except for the code inside x86_task.c and x86_task.h, which, deriving from KVM (the Linux kernel), is licensed GPL v2-only. This code base already implements a very great deal of functionality, although Google's version removed from Vertuu's the support for APIC page and hyperv-related stuff. According to the Android Emulator Release Notes, Revision 26.1.3 (August 2017), "Hypervisor.framework is now enabled by default on macOS for 32-bit x86 images to improve performance and macOS compatibility", although we better use with caution for, as the same Revision warns us, "If you experience issues with it specifically, please file a bug report...". The code hasn't seen much update in the last 5 months, so I think that we can further develop the code with occasional visiting Google's repository to see if there has been any update. On top of Google's code, the following changes were made: - add code to the configure script to support the --enable-hvf argument. If the OS is Darwin, it checks for presence of HVF in the system. The patch also adds strings related to HVF in the file qemu-options.hx. QEMU will only support the modern syntax style '-M accel=hvf' no enable hvf; the legacy '-enable-hvf' will not be supported. - fix styling issues - add glue code to cpus.c - move HVFX86EmulatorState field to CPUX86State, changing the the emulation functions to have a parameter with signature 'CPUX86State *' instead of 'CPUState *' so we don't have to get the 'env'.

Introduce qemu_madvise() vl.c has a Sun-specific hack to supply a prototype for madvise(), but the call site has apparently moved to arch_init.c. Haiku doesn't implement madvise() in favor of posix_madvise(). OpenBSD and Solaris 10 don't implement posix_madvise() but madvise(). MinGW implements neither. Check for madvise() and posix_madvise() in configure and supply qemu_madvise() as wrapper. Prefer madvise() over posix_madvise() due to flag availability. Convert all callers to use qemu_madvise() and QEMU_MADV_*. Note that on Solaris the warning is fixed by moving the madvise() prototype, not by qemu_madvise() itself. It helps with porting though, and it simplifies most call sites. v7 -> v8: * Some versions of MinGW have no sys/mman.h header. Reported by Blue Swirl. v6 -> v7: * Adopt madvise() rather than posix_madvise() semantics for returning errors. * Use EINVAL in place of ENOTSUP. v5 -> v6: * Replace two leftover instances of POSIX_MADV_NORMAL with QEMU_MADV_INVALID. Spotted by Blue Swirl. v4 -> v5: * Introduce QEMU_MADV_INVALID, suggested by Alexander Graf. Note that this relies on -1 not being a valid advice value. v3 -> v4: * Eliminate #ifdefs at qemu_advise() call sites. Requested by Blue Swirl. This will currently break the check in kvm-all.c by calling madvise() with a supported flag, which will not fail. Ideas/patches welcome. v2 -> v3: * Reuse the *_MADV_* defines for QEMU_MADV_*. Suggested by Alexander Graf. * Add configure check for madvise(), too. Add defines to Makefile, not QEMU_CFLAGS. Convert all callers, untested. Suggested by Blue Swirl. * Keep Solaris' madvise() prototype around. Pointed out by Alexander Graf. * Display configure check results. v1 -> v2: * Don't rely on posix_madvise() availability, add qemu_madvise(). Suggested by Blue Swirl.

vhost-scsi: new device supporting the tcm_vhost Linux kernel module The WWPN specified in configfs is passed to "-device vhost-scsi-pci". The tgpt field of the SET_ENDPOINT ioctl is obsolete now, so it is not available from the QEMU command-line. Instead, I hardcode it to zero. Changes in Patch-v2: - Add vhost_scsi_get_features() in order to determine feature bits supports by host kernel (mst + nab) - Re-enable usage of DEFINE_VIRTIO_COMMON_FEATURES, and allow EVENT_IDX to be disabled by host in vhost_scsi_get_features() - Drop unused hotplug bit in DEFINE_VHOST_SCSI_PROPERTIES Changes in Patch-v1: - Set event_idx=off by default (nab, thanks asias) - Disable hotplug feature bit for v3.9 tcm_vhost kernel code, need to re-enable in v3.10 (nab) - Update to latest qemu.git/master HEAD Changes in WIP-V3: - Drop ioeventfd vhost_scsi_properties (asias, thanks stefanha) - Add CONFIG_VHOST_SCSI (asias, thanks stefanha) - Add hotplug feature bit Changes in WIP-V2: - Add backend guest masking support (nab) - Bump ABI_VERSION to 1 (nab) - Set up set_guest_notifiers (asias) - Set up vs->dev.vq_index (asias) - Drop vs->vs.vdev.{set,clear}_vhost_endpoint (asias) - Drop VIRTIO_CONFIG_S_DRIVER check in vhost_scsi_set_status (asias) Howto: Use the latest seabios, at least commit b44a7be17b git clone git://git.seabios.org/seabios.git make cp out/bios.bin /usr/share/qemu/bios.bin qemu -device vhost-scsi-pci,wwpn=naa.6001405bd4e8476d,event_idx=off ...

iSCSI block driver This provides built-in support for iSCSI to QEMU. This has the advantage that the iSCSI devices need not be made visible to the host, which is useful if you have very many virtual machines and very many iscsi devices. It also has the benefit that non-root users of QEMU can access iSCSI devices across the network without requiring root privilege on the host. This driver interfaces with the multiplatform posix library for iscsi initiator/client access to iscsi devices hosted at git://github.com/sahlberg/libiscsi.git The patch adds the driver to interface with the iscsi library. It also updated the configure script to * by default, probe is libiscsi is available and if so, build qemu against libiscsi. * --enable-libiscsi Force a build against libiscsi. If libiscsi is not available the build will fail. * --disable-libiscsi Do not link against libiscsi, even if it is available. When linked with libiscsi, qemu gains support to access iscsi resources such as disks and cdrom directly, without having to make the devices visible to the host. You can specify devices using a iscsi url of the form : iscsi://[<username>[:<password>@]]<host>[:<port]/<target-iqn-name>/<lun> When using authentication, the password can optionally be set with LIBISCSI_CHAP_PASSWORD="password" to avoid it showing up in the process list Signed-off-by: Ronnie Sahlberg <ronniesahlberg@gmail.com> Reviewed-by: Stefan Hajnoczi <stefanha@linux.vnet.ibm.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>

configure: Add support for jemalloc This adds "--enable-jemalloc" and "--disable-jemalloc" to allow linking to jemalloc memory allocator. We have already tcmalloc support, but it seem to not working well with a lot of iothreads/disks. The main problem is that tcmalloc use a shared thread cache of 16MB by default. With more threads, this cache is shared, and some bad garbage collections can occur if the cache is too low. It's possible to tcmalloc cache increase it with a env var: TCMALLOC_MAX_TOTAL_THREAD_CACHE_BYTES=256MB With default 16MB, performances are really bad with more than 2 disks. Increasing to 256MB, it's helping but still have problem with 16 disks/iothreads. Jemalloc don't have performance problem with default configuration.

build: allow automatic git submodule updates to be disabled Some people building QEMU use VPATH builds where the source directory is on a read-only volume. In such a case 'scripts/git-submodules.sh update' will always fail and users are required to run it manually themselves on their original writable source directory. While this is already supported, it is nice to give users a command line flag to configure to permanently disable automatic submodule updates, as it means they won't get hard to diagnose failures from git-submodules.sh at an arbitrary later date. This patch thus introduces a flag '--disable-git-update' which will prevent 'make' from ever running 'scripts/git-submodules.sh update'. It will still run the 'status' command to determine if a submodule update is needed, but when it does this it'll simply stop and print a message instructing the developer what todo. eg $ ./configure --target-list=x86_64-softmmu --disable-git-update ...snip... $ make GEN config-host.h GEN trace/generated-tcg-tracers.h GEN trace/generated-helpers-wrappers.h GEN trace/generated-helpers.h GEN trace/generated-helpers.c GEN module_block.h GIT submodule checkout is out of date.

Add SASL authentication support ("Daniel P. Berrange") This patch adds the new SASL authentication protocol to the VNC server. It is enabled by setting the 'sasl' flag when launching VNC. SASL can optionally provide encryption via its SSF layer, if a suitable mechanism is configured (eg, GSSAPI/Kerberos, or Digest-MD5). If an SSF layer is not available, then it should be combined with the x509 VNC authentication protocol which provides encryption. eg, if using GSSAPI qemu -vnc localhost:1,sasl eg if using TLS/x509 for encryption qemu -vnc localhost:1,sasl,tls,x509 By default the Cyrus SASL library will look for its configuration in the file /etc/sasl2/qemu.conf. For non-root users, this can be overridden by setting the SASL_CONF_PATH environment variable, eg to make it look in $HOME/.sasl2. NB unprivileged users may not have access to the full range of SASL mechanisms, since some of them require some administrative privileges to configure. The patch includes an example SASL configuration file which illustrates config for GSSAPI and Digest-MD5, though it should be noted that the latter is not really considered secure any more. Most of the SASL authentication code is located in a separate source file, vnc-auth-sasl.c. The main vnc.c file only contains minimal integration glue, specifically parsing of command line flags / setup, and calls to start the SASL auth process, to do encoding/decoding for data. There are several possible stacks for reading & writing of data, depending on the combo of VNC authentication methods in use - Clear. read/write straight to socket - TLS. read/write via GNUTLS helpers - SASL. encode/decode via SASL SSF layer, then read/write to socket - SASL+TLS. encode/decode via SASL SSF layer, then read/write via GNUTLS Hence, the vnc_client_read & vnc_client_write methods have been refactored a little. vnc_client_read: main entry point for reading, calls either - vnc_client_read_plain reading, with no intermediate decoding - vnc_client_read_sasl reading, with SASL SSF decoding These two methods, then call vnc_client_read_buf(). This decides whether to write to the socket directly or write via GNUTLS. The situation is the same for writing data. More extensive comments have been added in the code / patch. The vnc_client_read_sasl and vnc_client_write_sasl method implementations live in the separate vnc-auth-sasl.c file. The state required for the SASL auth mechanism is kept in a separate VncStateSASL struct, defined in vnc-auth-sasl.h and included in the main VncState. The configure script probes for SASL and automatically enables it if found, unless --disable-vnc-sasl was given to override it.

authz: add QAuthZPAM object type for authorizing using PAM Add an authorization backend that talks to PAM to check whether the user identity is allowed. This only uses the PAM account validation facility, which is essentially just a check to see if the provided username is permitted access. It doesn't use the authentication or session parts of PAM, since that's dealt with by the relevant part of QEMU (eg VNC server). Consider starting QEMU with a VNC server and telling it to use TLS with x509 client certificates and configuring it to use an PAM to validate the x509 distinguished name. In this example we're telling it to use PAM for the QAuthZ impl with a service name of "qemu-vnc" $ qemu-system-x86_64 \ -object tls-creds-x509,id=tls0,dir=/home/berrange/security/qemutls,\ endpoint=server,verify-peer=yes \ -object authz-pam,id=authz0,service=qemu-vnc \ -vnc :1,tls-creds=tls0,tls-authz=authz0 This requires an /etc/pam/qemu-vnc file to be created with the auth rules. A very simple file based whitelist can be setup using $ cat > /etc/pam/qemu-vnc <<EOF account requisite pam_listfile.so item=user sense=allow file=/etc/qemu/vnc.allow EOF The /etc/qemu/vnc.allow file simply contains one username per line. Any username not in the file is denied. The usernames in this example are the x509 distinguished name from the client's x509 cert. $ cat > /etc/qemu/vnc.allow <<EOF CN=laptop.berrange.com,O=Berrange Home,L=London,ST=London,C=GB EOF More interesting would be to configure PAM to use an LDAP backend, so that the QEMU authorization check data can be centralized instead of requiring each compute host to have file maintained. The main limitation with this PAM module is that the rules apply to all QEMU instances on the host. Setting up different rules per VM, would require creating a separate PAM service name & config file for every guest. An alternative approach for the future might be to not pass in the plain username to PAM, but instead combine the VM name or UUID with the username. This requires further consideration though.

vhost-scsi: new device supporting the tcm_vhost Linux kernel module The WWPN specified in configfs is passed to "-device vhost-scsi-pci". The tgpt field of the SET_ENDPOINT ioctl is obsolete now, so it is not available from the QEMU command-line. Instead, I hardcode it to zero. Changes in Patch-v2: - Add vhost_scsi_get_features() in order to determine feature bits supports by host kernel (mst + nab) - Re-enable usage of DEFINE_VIRTIO_COMMON_FEATURES, and allow EVENT_IDX to be disabled by host in vhost_scsi_get_features() - Drop unused hotplug bit in DEFINE_VHOST_SCSI_PROPERTIES Changes in Patch-v1: - Set event_idx=off by default (nab, thanks asias) - Disable hotplug feature bit for v3.9 tcm_vhost kernel code, need to re-enable in v3.10 (nab) - Update to latest qemu.git/master HEAD Changes in WIP-V3: - Drop ioeventfd vhost_scsi_properties (asias, thanks stefanha) - Add CONFIG_VHOST_SCSI (asias, thanks stefanha) - Add hotplug feature bit Changes in WIP-V2: - Add backend guest masking support (nab) - Bump ABI_VERSION to 1 (nab) - Set up set_guest_notifiers (asias) - Set up vs->dev.vq_index (asias) - Drop vs->vs.vdev.{set,clear}_vhost_endpoint (asias) - Drop VIRTIO_CONFIG_S_DRIVER check in vhost_scsi_set_status (asias) Howto: Use the latest seabios, at least commit b44a7be17b git clone git://git.seabios.org/seabios.git make cp out/bios.bin /usr/share/qemu/bios.bin qemu -device vhost-scsi-pci,wwpn=naa.6001405bd4e8476d,event_idx=off ...

qemu-io: Add generic function for reinitializing optind. On FreeBSD 11.2: $ nbdkit memory size=1M --run './qemu-io -f raw -c "aio_write 0 512" $nbd' Parsing error: non-numeric argument, or extraneous/unrecognized suffix -- aio_write After main option parsing, we reinitialize optind so we can parse each command. However reinitializing optind to 0 does not work on FreeBSD. What happens when you do this is optind remains 0 after the option parsing loop, and the result is we try to parse argv[optind] == argv[0] == "aio_write" as if it was the first parameter. The FreeBSD manual page says: In order to use getopt() to evaluate multiple sets of arguments, or to evaluate a single set of arguments multiple times, the variable optreset must be set to 1 before the second and each additional set of calls to getopt(), and the variable optind must be reinitialized. (From the rest of the man page it is clear that optind must be reinitialized to 1). The glibc man page says: A program that scans multiple argument vectors, or rescans the same vector more than once, and wants to make use of GNU extensions such as '+' and '-' at the start of optstring, or changes the value of POSIXLY_CORRECT between scans, must reinitialize getopt() by resetting optind to 0, rather than the traditional value of 1. (Resetting to 0 forces the invocation of an internal initialization routine that rechecks POSIXLY_CORRECT and checks for GNU extensions in optstring.) This commit introduces an OS-portability function called qemu_reset_optind which provides a way of resetting optind that works on FreeBSD and platforms that use optreset, while keeping it the same as now on other platforms. Note that the qemu codebase sets optind in many other places, but in those other places it's setting a local variable and not using getopt. This change is only needed in places where we are using getopt and the associated global variable optind. Signed-off-by: Richard W.M.

Introduce qemu_madvise() vl.c has a Sun-specific hack to supply a prototype for madvise(), but the call site has apparently moved to arch_init.c. Haiku doesn't implement madvise() in favor of posix_madvise(). OpenBSD and Solaris 10 don't implement posix_madvise() but madvise(). MinGW implements neither. Check for madvise() and posix_madvise() in configure and supply qemu_madvise() as wrapper. Prefer madvise() over posix_madvise() due to flag availability. Convert all callers to use qemu_madvise() and QEMU_MADV_*. Note that on Solaris the warning is fixed by moving the madvise() prototype, not by qemu_madvise() itself. It helps with porting though, and it simplifies most call sites. v7 -> v8: * Some versions of MinGW have no sys/mman.h header. Reported by Blue Swirl. v6 -> v7: * Adopt madvise() rather than posix_madvise() semantics for returning errors. * Use EINVAL in place of ENOTSUP. v5 -> v6: * Replace two leftover instances of POSIX_MADV_NORMAL with QEMU_MADV_INVALID. Spotted by Blue Swirl. v4 -> v5: * Introduce QEMU_MADV_INVALID, suggested by Alexander Graf. Note that this relies on -1 not being a valid advice value. v3 -> v4: * Eliminate #ifdefs at qemu_advise() call sites. Requested by Blue Swirl. This will currently break the check in kvm-all.c by calling madvise() with a supported flag, which will not fail. Ideas/patches welcome. v2 -> v3: * Reuse the *_MADV_* defines for QEMU_MADV_*. Suggested by Alexander Graf. * Add configure check for madvise(), too. Add defines to Makefile, not QEMU_CFLAGS. Convert all callers, untested. Suggested by Blue Swirl. * Keep Solaris' madvise() prototype around. Pointed out by Alexander Graf. * Display configure check results. v1 -> v2: * Don't rely on posix_madvise() availability, add qemu_madvise(). Suggested by Blue Swirl.

iSCSI block driver This provides built-in support for iSCSI to QEMU. This has the advantage that the iSCSI devices need not be made visible to the host, which is useful if you have very many virtual machines and very many iscsi devices. It also has the benefit that non-root users of QEMU can access iSCSI devices across the network without requiring root privilege on the host. This driver interfaces with the multiplatform posix library for iscsi initiator/client access to iscsi devices hosted at git://github.com/sahlberg/libiscsi.git The patch adds the driver to interface with the iscsi library. It also updated the configure script to * by default, probe is libiscsi is available and if so, build qemu against libiscsi. * --enable-libiscsi Force a build against libiscsi. If libiscsi is not available the build will fail. * --disable-libiscsi Do not link against libiscsi, even if it is available. When linked with libiscsi, qemu gains support to access iscsi resources such as disks and cdrom directly, without having to make the devices visible to the host. You can specify devices using a iscsi url of the form : iscsi://[<username>[:<password>@]]<host>[:<port]/<target-iqn-name>/<lun> When using authentication, the password can optionally be set with LIBISCSI_CHAP_PASSWORD="password" to avoid it showing up in the process list Signed-off-by: Ronnie Sahlberg <ronniesahlberg@gmail.com> Reviewed-by: Stefan Hajnoczi <stefanha@linux.vnet.ibm.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>

oslib-win32: only provide localtime_r/gmtime_r if missing The oslib-win32 file currently provides a localtime_r and gmtime_r replacement unconditionally. Some versions of Mingw-w64 would provide crude macros for localtime_r/gmtime_r which QEMU takes care to disable. Latest versions of Mingw-w64 now provide actual functions for localtime_r/gmtime_r, but with a twist that you have to include unistd.h or pthread.h before including time.h. By luck some files in QEMU have such an include order, resulting in compile errors: CC util/osdep.o In file included from include/qemu-common.h:48:0, from util/osdep.c:48: include/sysemu/os-win32.h:77:12: error: redundant redeclaration of 'gmtime_r' [-Werror=redundant-decls] struct tm *gmtime_r(const time_t *timep, struct tm *result); ^ In file included from include/qemu-common.h:35:0, from util/osdep.c:48: /usr/i686-w64-mingw32/sys-root/mingw/include/time.h:272:107: note: previous definition of 'gmtime_r' was here In file included from include/qemu-common.h:48:0, from util/osdep.c:48: include/sysemu/os-win32.h:79:12: error: redundant redeclaration of 'localtime_r' [-Werror=redundant-decls] struct tm *localtime_r(const time_t *timep, struct tm *result); ^ In file included from include/qemu-common.h:35:0, from util/osdep.c:48: /usr/i686-w64-mingw32/sys-root/mingw/include/time.h:269:107: note: previous definition of 'localtime_r' was here This change adds a configure test to see if localtime_r exits, and only enables the QEMU impl if missing.

use _Static_assert in QEMU_BUILD_BUG_ON QEMU_BUILD_BUG_ON should use C11's _Static_assert, if the compiler supports it, to provide more readable messages on failure. We check for _Static_assert in configure, and set CONFIG_STATIC_ASSERT accordingly. QEMU_BUILD_BUG_ON invokes _Static_assert if CONFIG_STATIC_ASSERT is defined, and reverts to the old way otherwise. That way, systems without C11 conforming compiler will still have the old messages, as verified by intentionally breaking the configure check. the following example output was generated by inverting the condition in QEMU_BUILD_BUG_ON: without _Static_assert: > In file included from /qemu/include/qemu/osdep.h:36:0, > from /qemu/qga/commands.c:13: > /qemu/qga/commands.c: In function ‘qmp_guest_exec_status’: > /qemu/include/qemu/compiler.h:89:12: error: negative width in bit-field ‘<anonymous>’ > struct { \ > ^ > /qemu/include/qemu/compiler.h:96:38: note: in expansion of macro QEMU_BUILD_BUG_ON_STRUCT’ > #define QEMU_BUILD_BUG_ON(x) typedef QEMU_BUILD_BUG_ON_STRUCT(x) \ > ^~~~~~~~~~~~~~~~~~~~~~~~ > /qemu/include/qemu/atomic.h:146:5: note: in expansion of macro ‘QEMU_BUILD_BUG_ON’ > QEMU_BUILD_BUG_ON(sizeof(*ptr) > sizeof(void *)); \ > ^~~~~~~~~~~~~~~~~ > /qemu/include/qemu/atomic.h:417:5: note: in expansion of macro ‘atomic_load_acquire’ > atomic_load_acquire(ptr) > ^~~~~~~~~~~~~~~~~~~ > /qemu/qga/commands.c:160:21: note: in expansion of macro ‘atomic_mb_read’ > bool finished = atomic_mb_read(&gei->finished); > ^~~~~~~~~~~~~~ with _Static_assert: > In file included from /qemu/include/qemu/osdep.h:36:0, > from /qemu/qga/commands.c:13: > /qemu/qga/commands.c: In function ‘qmp_guest_exec_status’: > /qemu/include/qemu/compiler.h:94:30: error: static assertion failed: "not expecting: sizeof(*&gei->finished) > sizeof(void *)" > #define QEMU_BUILD_BUG_ON(x) _Static_assert((x), #x) > ^ > /qemu/include/qemu/atomic.h:146:5: note: in expansion of macro ‘QEMU_BUILD_BUG_ON’ > QEMU_BUILD_BUG_ON(sizeof(*ptr) > sizeof(void *)); \ > ^~~~~~~~~~~~~~~~~ > /qemu/include/qemu/atomic.h:417:5: note: in expansion of macro ‘atomic_load_acquire’ > atomic_load_acquire(ptr) > ^~~~~~~~~~~~~~~~~~~ > /qemu/qga/commands.c:160:21: note: in expansion of macro ‘atomic_mb_read’ > bool finished = atomic_mb_read(&gei->finished); > ^~~~~~~~~~~~~~ Signed-off-by: Andreas Grapentin <andreas@grapentin.org> Message-Id: <20170314165953.18506-1-andreas@grapentin.org> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

configure: Really use local libfdt if the system one is too old QEMU requires libfdt version >= 1.4.2. If the host has an older libfdt installed, the configure script will use a (git cloned) local version. Example with Debian 8: $ dpkg-query --showformat='${Version}\n' --show libfdt-dev 1.4.0+dfsg-1 $ ./configure [...] fdt support yes # from git submodule 'dtc' If this case occurs, the linker will have 2 different libfdt available in the library search path. The default behavior is to search the system path first, then the local path. Even if the configure script noticed the libfdt is too old and clone a more recent locally, when linking the system library is selected first, and the link process eventually fails: LINK mips64el-softmmu/qemu-system-mips64el ../hw/core/loader-fit.o: In function `load_fit': /root/src/github.com/philmd/qemu/hw/core/loader-fit.c:278: undefined reference to `fdt_first_subnode' /root/src/github.com/philmd/qemu/hw/core/loader-fit.c:286: undefined reference to `fdt_next_subnode' /root/src/github.com/philmd/qemu/hw/core/loader-fit.c:277: undefined reference to `fdt_first_subnode' collect2: error: ld returned 1 exit status Makefile:201: recipe for target 'qemu-system-mips64el' failed make[1]: *** [qemu-system-mips64el] Error 1 QEMU already uses a kludge to enforce local CFLAGS before system ones for libpixman and libfdt, add a similar kludge for the LDFLAGS to enforce using the local libfdt.

tests: introduce a framework for testing migration performance This introduces a moderately general purpose framework for testing performance of migration. The initial guest workload is provided by the included 'stress' program, which is configured to spawn one thread per guest CPU and run a maximally memory intensive workload. It will loop over GB of memory, xor'ing each byte with data from a 4k array of random bytes. This ensures heavy read and write load across all of guest memory to stress the migration performance. While running the 'stress' program will record how long it takes to xor each GB of memory and print this data for later reporting. The test engine will spawn a pair of QEMU processes, either on the same host, or with the target on a remote host via ssh, using the host kernel and a custom initrd built with 'stress' as the /init binary. Kernel command line args are set to ensure a fast kernel boot time (< 1 second) between launching QEMU and the stress program starting execution. None the less, the test engine will initially wait N seconds for the guest workload to stablize, before starting the migration operation. When migration is running, the engine will use pause, post-copy, autoconverge, xbzrle compression and multithread compression features, as well as downtime & bandwidth tuning to encourage completion. If migration completes, the test engine will wait N seconds again for the guest workooad to stablize on the target host. If migration does not complete after a preset number of iterations, it will be aborted. While the QEMU process is running on the source host, the test engine will sample the host CPU usage of QEMU as a whole, and each vCPU thread. While migration is running, it will record all the stats reported by 'query-migration'. Finally, it will capture the output of the stress program running in the guest. All the data produced from a single test execution is recorded in a structured JSON file. A separate program is then able to create interactive charts using the "plotly" python + javascript libraries, showing the characteristics of the migration. The data output provides visualization of the effect on guest vCPU workloads from the migration process, the corresponding vCPU utilization on the host, and the overall CPU hit from QEMU on the host. This is correlated from statistics from the migration process, such as downtime, vCPU throttling and iteration number. While the tests can be run individually with arbitrary parameters, there is also a facility for producing batch reports for a number of pre-defined scenarios / comparisons, in order to be able to get standardized results across different hardware configurations (eg TCP vs RDMA, or comparing different VCPU counts / memory sizes, etc). To use this, first you must build the initrd image $ make tests/migration/initrd-stress.img To run a a one-shot test with all default parameters $ ./tests/migration/guestperf.py > result.json This has many command line args for varying its behaviour. For example, to increase the RAM size and CPU count and bind it to specific host NUMA nodes $ ./tests/migration/guestperf.py \ --mem 4 --cpus 2 \ --src-mem-bind 0 --src-cpu-bind 0,1 \ --dst-mem-bind 1 --dst-cpu-bind 2,3 \ > result.json Using mem + cpu binding is strongly recommended on NUMA machines, otherwise the guest performance results will vary wildly between runs of the test due to lucky/unlucky NUMA placement, making sensible data analysis impossible. To make it run across separate hosts: $ ./tests/migration/guestperf.py \ --dst-host somehostname > result.json To request that post-copy is enabled, with switchover after 5 iterations $ ./tests/migration/guestperf.py \ --post-copy --post-copy-iters 5 > result.json Once a result.json file is created, a graph of the data can be generated, showing guest workload performance per thread and the migration iteration points: $ ./tests/migration/guestperf-plot.py --output result.html \ --migration-iters --split-guest-cpu result.json To further include host vCPU utilization and overall QEMU utilization $ ./tests/migration/guestperf-plot.py --output result.html \ --migration-iters --split-guest-cpu \ --qemu-cpu --vcpu-cpu result.json NB, the 'guestperf-plot.py' command requires that you have the plotly python library installed. eg you must do $ pip install --user plotly Viewing the result.html file requires that you have the plotly.min.js file in the same directory as the HTML output. This js file is installed as part of the plotly python library, so can be found in $HOME/.local/lib/python2.7/site-packages/plotly/offline/plotly.min.js The guestperf-plot.py program can accept multiple json files to plot, enabling results from different configurations to be compared. Finally, to run the entire standardized set of comparisons $ ./tests/migration/guestperf-batch.py \ --dst-host somehost \ --mem 4 --cpus 2 \ --src-mem-bind 0 --src-cpu-bind 0,1 \ --dst-mem-bind 1 --dst-cpu-bind 2,3 --output tcp-somehost-4gb-2cpu will store JSON files from all scenarios in the directory named tcp-somehost-4gb-2cpu Signed-off-by: Daniel P.

i386: hvf: add code base from Google's QEMU repository This file begins tracking the files that will be the code base for HVF support in QEMU. This code base is part of Google's QEMU version of their Android emulator, and can be found at https://android.googlesource.com/platform/external/qemu/+/emu-master-dev This code is based on Veertu Inc's vdhh (Veertu Desktop Hosted Hypervisor), found at https://github.com/veertuinc/vdhh. Everything is appropriately licensed under GPL v2-or-later, except for the code inside x86_task.c and x86_task.h, which, deriving from KVM (the Linux kernel), is licensed GPL v2-only. This code base already implements a very great deal of functionality, although Google's version removed from Vertuu's the support for APIC page and hyperv-related stuff. According to the Android Emulator Release Notes, Revision 26.1.3 (August 2017), "Hypervisor.framework is now enabled by default on macOS for 32-bit x86 images to improve performance and macOS compatibility", although we better use with caution for, as the same Revision warns us, "If you experience issues with it specifically, please file a bug report...". The code hasn't seen much update in the last 5 months, so I think that we can further develop the code with occasional visiting Google's repository to see if there has been any update. On top of Google's code, the following changes were made: - add code to the configure script to support the --enable-hvf argument. If the OS is Darwin, it checks for presence of HVF in the system. The patch also adds strings related to HVF in the file qemu-options.hx. QEMU will only support the modern syntax style '-M accel=hvf' no enable hvf; the legacy '-enable-hvf' will not be supported. - fix styling issues - add glue code to cpus.c - move HVFX86EmulatorState field to CPUX86State, changing the the emulation functions to have a parameter with signature 'CPUX86State *' instead of 'CPUState *' so we don't have to get the 'env'.

configure: preserve various environment variables in config.status The config.status script is auto-generated by configure upon completion. The intention is that config.status can be later invoked by the developer directly, or by make indirectly, to re-detect the same environment that configure originally used. The current config.status script, however, only contains a record of the command line arguments to configure. Various environment variables have an effect on what configure will find. In particular PKG_CONFIG_LIBDIR & PKG_CONFIG_PATH vars will affect what libraries pkg-config finds. The PATH var will affect what toolchain binaries and XXXX-config scripts are found. The LD_LIBRARY_PATH var will affect what libraries are found. Most commands have env variables that will override the name/path of the default version configure finds. All these key env variables should be recorded in the config.status script. Autoconf would also preserve CFLAGS, LDFLAGS, LIBS, CPPFLAGS, but QEMU deals with those differently, expecting extra flags to be set using configure args, rather than env variables. At the end of the script we also don't have the original values of those env vars, as we modify them during configure.
