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.

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 The tgpt field of the SET_ENDPOINT ioctl is obsolete now, so it is not available from the QEMU command-line.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.

tcg: initial ia64 support A few words about design choices: * On IA64, instructions should be grouped by bundle, and dependencies between instructions declared. A first version of this code tried to schedule instructions automatically, but was very complex and too invasive for the current common TCG code (ops not ending at instruction boundaries, code retranslation breaking already generated code, etc.) It was also not very efficient, as dependencies between TCG ops is not available. Instead the option taken by the current implementation does not try to fill the bundle by scheduling instructions, but by providing ops not available as an ia64 instruction, and by offering 22-bit constant loading for most of the instructions. With both options the bundle are filled at approximately the same level. * Up to 128 registers can be affected to a function on IA64, but TCG limits this number to 64, which is actually more than enough. The register affectation is the following: - r0: used to map a constant argument with value 0 - r1: global pointer - r2, r3: internal use - r4 to r6: not used to avoid saving them - r7: env structure - r8 to r11: free for TCG (call clobbered) - r12: stack pointer - r13: thread pointer - r14 to r31: free for TCG (call clobbered) - r32: reserved (return address) - r33: reserved (PFS) - r33 to r63: free for TCG * The IA64 architecture has only 64-bit registers and no 32-bit instructions (the only exception being cmp4). Therefore 64-bit registers and instructions are used for 32-bit ops. The adopted strategy is the same as the ABI, that is the higher 32 bits are undefined. Most ops (and, or, add, shl, etc.) can directly use the 64-bit registers, while some others have to sign-extend (sar, div, etc.) or zero-extend (shr, divu, etc.) the register first.

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 ...

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 ...

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. Here the benchmark results in iops of 1 qemu vm randread 4K iodepth=32, with rbd block backend (librbd is doing a lot of memory allocation), 1 iothread by disk glibc malloc ------------ 1 disk 29052 2 disks 55878 4 disks 127899 8 disks 240566 15 disks 269976 jemalloc -------- 1 disk 41278 2 disks 75781 4 disks 195351 8 disks 294241 15 disks 298199 tcmalloc 2.2.1 default 16M cache -------------------------------- 1 disk 37911 2 disks 67698 4 disks 41076 8 disks 43312 15 disks 37569 tcmalloc : 256M cache --------------------------- 1 disk 33914 2 disks 58839 4 disks 148205 8 disks 213298 15 disks 218383 Signed-off-by: Alexandre Derumier <aderumier@odiso.com> Message-Id: <1434711418-20429-1-git-send-email-aderumier@odiso.com> Signed-off-by: Paolo Bonzini <pbonzini@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. Here the benchmark results in iops of 1 qemu vm randread 4K iodepth=32, with rbd block backend (librbd is doing a lot of memory allocation), 1 iothread by disk glibc malloc ------------ 1 disk 29052 2 disks 55878 4 disks 127899 8 disks 240566 15 disks 269976 jemalloc -------- 1 disk 41278 2 disks 75781 4 disks 195351 8 disks 294241 15 disks 298199 tcmalloc 2.2.1 default 16M cache -------------------------------- 1 disk 37911 2 disks 67698 4 disks 41076 8 disks 43312 15 disks 37569 tcmalloc : 256M cache --------------------------- 1 disk 33914 2 disks 58839 4 disks 148205 8 disks 213298 15 disks 218383 Signed-off-by: Alexandre Derumier <aderumier@odiso.com> Message-Id: <1434711418-20429-1-git-send-email-aderumier@odiso.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

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.

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.

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.

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.

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.

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: 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.

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_*.

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_*.

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.

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>

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.

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.

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.

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 ...

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.

usb-ccid: add CCID bus A CCID device is a smart card reader. It is a USB device, defined at [1]. This patch introduces the usb-ccid device that is a ccid bus. Next patches will introduce two card types to use it, a passthru card and an emulated card. [1] http://www.usb.org/developers/devclass_docs/DWG_Smart-Card_CCID_Rev110. Signed-off-by: Alon Levy <alevy@redhat.com> --- changes from v20->v21: (Jes Sorenson review) * cosmetic changes - fix multi line comments. * reorder fields in USBCCIDState * add reference to COPYING * add --enable-smartcard and --disable-smartcard here (moved from last patch) changes from v19->v20: * checkpatch.pl changes from v18->v19: * merged: ccid.h: add copyright, fix define and remove non C89 comments * add qdev.desc changes from v15->v16: Behavioral changes: * fix abort on client answer after card remove * enable migration * remove side affect code from asserts * return consistent self-powered state * mask out reserved bits in ccid_set_parameters * add missing abRFU in SetParameters (no affect on linux guest) whitefixes / comments / consts defines: * remove stale comment * remove ccid_print_pending_answers if no DEBUG_CCID * replace printf's with DPRINTF, remove DEBUG_CCID, add verbosity defines * use error_report * update copyright (most of the code is not original) * reword known bug comment * add missing closing quote in comment * add missing whitespace on one line * s/CCID_SetParameter/CCID_SetParameters/ * add comments * use define for max packet size Comment for "return consistent self-powered state": the Configuration Descriptor bmAttributes claims we are self powered, but we were returning not self powered to USB_REQ_GET_STATUS control message.

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. 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.

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.
