Greg Kurz aee7f3ecd8 fsdev: Error out when unsupported option is passed
Each fsdriver only supports a subset of the options that can be passed
to -fsdev. Unsupported options are simply ignored. This could cause the
user to erroneously think QEMU has a bug.

Enforce strict checking of supported options for all fsdrivers. This
shouldn't impact libvirt, since it doesn't know about the synth and
proxy fsdrivers.

Greg Kurz 2023243573 fsdev: Move some types definition to qemu-fsdev.c
It would make sense for these types to be defined in a header file if
we had an API for fsdrivers to register themselves. In practice, we
only have three of them and it is very unlikely we add new ones since
the future of file sharing between host and guest is the upcoming
virtio-fs.

Move the types to qemu-fsdev.c instead since they are only used there.

Paolo Bonzini b58deb344d qemu/queue.h: leave head structs anonymous unless necessary
Most list head structs need not be given a name.  In most cases the
name is given just in case one is going to use QTAILQ_LAST, QTAILQ_PREV
or reverse iteration, but this does not apply to lists of other kinds,
and even for QTAILQ in practice this is only rarely needed.  In addition,
we will soon reimplement those macros completely so that they do not
need a name for the head struct.  So clean up everything, not giving a
name except in the rare case where it is necessary.

The "handle" fsdev backend was deprecated in QEMU 2.12.0 with:

commit db3b3c7281
Author: Greg Kurz <groug@kaod.org>
Date:   Mon Jan 8 11:18:23 2018 +0100

    9pfs: deprecate handle backend

    This backend raise some concerns:

    - doesn't support symlinks
    - fails +100 tests in the PJD POSIX file system test suite [1]
    - requires the QEMU process to run with the CAP_DAC_READ_SEARCH
      capability, which isn't recommended for security reasons

    This backend should not be used and wil be removed. The 'local'
    backend is the recommended alternative.

Markus Armbruster b836723dfe fsdev: Clean up error reporting in qemu_fsdev_add()
Calling error_report() from within a function that takes an Error **
argument is suspicious.  qemu_fsdev_add() does that, and its caller
fsdev_init_func() then fails without setting an error.  Its caller

Paolo Bonzini 5261dd7b01 coroutine-lock: make qemu_co_enter_next thread-safe
qemu_co_queue_next does not need to release and re-acquire the mutex,
because the queued coroutine does not run immediately.  However, this
does not hold for qemu_co_enter_next.  Now that qemu_co_queue_wait
can synchronize (via QemuLockable) with code that is not running in
coroutine context, it's important that code using qemu_co_enter_next
can easily use a standardized locking idiom.

First of all, qemu_co_enter_next must use aio_co_wake to restart the
coroutine.  Second, the function gains a second argument, a QemuLockable*,
and the comments of qemu_co_queue_next and qemu_co_queue_restart_all
are adjusted to clarify the difference.

Manos Pitsidianakis 27e4cf1303 block: remove timer canceling in throttle_config()
throttle_config() cancels the timers of the calling BlockBackend. This
doesn't make sense because other BlockBackends in the group remain
untouched. There's no need to cancel the timers in the one specific
BlockBackend so let's not do that. Throttled requests will run as
scheduled and future requests will follow the new configuration. This
also allows a throttle group's configuration to be changed even when it
has no members.

Tobias Schramm b96feb2cb9 9pfs: local: Add support for custom fmode/dmode in 9ps mapped security modes
In mapped security modes, files are created with very restrictive
permissions (600 for files and 700 for directories). This makes
file sharing between virtual machines and users on the host rather
complicated. Imagine eg. a group of users that need to access data
produced by processes on a virtual machine. Giving those users access
to the data will be difficult since the group access mode is always 0.

This patch makes the default mode for both files and directories
configurable. Existing setups that don't know about the new parameters
keep using the current secure behavior.

Li Qiang ba42ebb863 9pfs: allocate space for guest originated empty strings
If a guest sends an empty string paramater to any 9P operation, the current
code unmarshals it into a V9fsString equal to { .size = 0, .data = NULL }.

This is unfortunate because it can cause NULL pointer dereference to happen
at various locations in the 9pfs code. And we don't want to check str->data
everywhere we pass it to strcmp() or any other function which expects a
dereferenceable pointer.

This patch enforces the allocation of genuine C empty strings instead, so
callers don't have to bother.

Out of all v9fs_iov_vunmarshal() users, only v9fs_xattrwalk() checks if
the returned string is empty. It now uses v9fs_string_size() since
name.data cannot be NULL anymore.

Greg Kurz 635324e83e 9p: switch back to readdir()
This patch changes the 9p code to use readdir() again instead of
readdir_r(), which is deprecated in glibc 2.24.

All the locking was put in place by a previous patch.

Greg Kurz af8b38b0d1 9p/fsdev: remove obsolete references to virtio
Most of the 9p code is now virtio agnostic. This patch does a final cleanup:
- drop references to Virtio from the header comments
- fix includes

Also drop a couple of leading empty lines while here.

Eduardo Habkost 34294e2f54 module: Rename machine_init() to opts_init()
The only remaining users of machine_init() only call
qemu_add_opts(). Rename machine_init() to opts_init() and move it
closer to the qemu_add_opts() calls on vl.c.

reformulates the sentence the typo was in to make it easier to grasp.
This is based on a suggestion from Eric Blake.

Wei Liu 2209bd050a fsdev: rename virtio-9p-marshal.{c,h} to 9p-iov-marshal.{c,h}
And rename v9fs_marshal to v9fs_iov_marshal, v9fs_unmarshal to
v9fs_iov_unmarshal.

The rationale behind this change is that, this marshalling interface is
used both by virtio and proxy helper. Renaming files and functions to
reflect the true nature of this interface.

Xen transport is going to have its own marshalling interface.
