[pve-devel] [PATCH pve-qemu 1/3] udpate and rebase to QEMU v6.0.0

Stefan Reiter s.reiter at proxmox.com
Thu May 27 12:43:32 CEST 2021


Mostly minor changes, bigger ones summarized:
* QEMU's internal backup code now uses a new async system, which allows
  parallel requests - the default max_workers settings is 64, I chose
  less, since 64 put enough stress on QEMU that the guest became
  practically unusable during the backup, and 16 still shows quite a
  nice measureable performance improvement. Little code changes for us
  though.
* 'malformed' QAPI parameters/functions are now a build error (i.e.
  using '_' vs '-'), I chose to just whitelist our calls in the name of
  backwards compatibility.
* monitor OOB race fix now uses the upstream variant, cherry-picked from
  origin/master since it's not in 6.0 by default
* last patch fixes a bug with snapshot rollback related to the new yank
  system

+Subject: [PATCH] monitor/qmp: fix race on CHR_EVENT_CLOSED without OOB
+
+The QMP dispatcher coroutine holds the qmp_queue_lock over a yield
+point, where it expects to be rescheduled from the main context. If a
+CHR_EVENT_CLOSED event is received just then, it can race and block the
+main thread on the mutex in monitor_qmp_cleanup_queue_and_resume.
+
+monitor_resume does not need to be called from main context, so we can
+call it immediately after popping a request from the queue, which allows
+us to drop the qmp_queue_lock mutex before yielding.

-
-Existing callers don't need the struct lo_inode so the function doesn't

-Subject: [PATCH] virtiofsd: prevent opening of special files (CVE-2020-35517)
-
-A well-behaved FUSE client does not attempt to open special files with
-FUSE_OPEN because they are handled on the client side (e.g. device nodes
-are handled by client-side device drivers).
-
-The check to prevent virtiofsd from opening special files is missing in
-a few cases, most notably FUSE_OPEN. A malicious client can cause
-virtiofsd to open a device node, potentially allowing the guest to
-escape. This can be exploited by a modified guest device driver. It is
-not exploitable from guest userspace since the guest kernel will handle
-special files inside the guest instead of sending FUSE requests.
-
-This patch fixes this issue by introducing the lo_inode_open() function
-to check the file type before opening it. This is a short-term solution
-because it does not prevent a compromised virtiofsd process from opening
-device nodes on the host.
-
-Restructure lo_create() to try O_CREAT | O_EXCL first. Note that O_CREAT

-necessary here. If the file exists and the user did not specify O_EXCL,
-open it via lo_do_open().

-Subject: [PATCH] i386/acpi: restore device paths for pre-5.1 vms
-
-After fixing the _UID value for the primary PCI root bridge in
-af1b80ae it was discovered that this change updates Windows
-configuration in an incompatible way causing network configuration
-failure unless DHCP is used. More details provided on the list:
-
-https://lists.gnu.org/archive/html/qemu-devel/2021-02/msg08484.html
-
-This change reverts the _UID update from 1 to 0 for q35 and i440fx
-VMs before version 5.2 to maintain the original behaviour when
-upgrading.

-Subject: [PATCH] monitor/qmp: fix race on CHR_EVENT_CLOSED without OOB
-
-The QMP dispatcher coroutine holds the qmp_queue_lock over a yield
-point, where it expects to be rescheduled from the main context. If a
-CHR_EVENT_CLOSED event is received just then, it can race and block the
-main thread on the mutex in monitor_qmp_cleanup_queue_and_resume.
-
-Calculate need_resume immediately after we pop a request from the queue,
-so that we can release the mutex before yielding.

-Subject: [PATCH] block: Fix deadlock in bdrv_co_yield_to_drain()
-
-If bdrv_co_yield_to_drain() is called for draining a block node that
-runs in a different AioContext, it keeps that AioContext locked while it
-yields and schedules a BH in the AioContext to do the actual drain.
-
-As long as executing the BH is the very next thing that the event loop
-of the node's AioContext does, this actually happens to work, but when
-it tries to execute something else that wants to take the AioContext
-lock, it will deadlock. (In the bug report, this other thing is a
-virtio-scsi device running virtio_scsi_data_plane_handle_cmd().)
-
-Instead, always drop the AioContext lock across the yield and reacquire
-it only when the coroutine is reentered. The BH needs to unconditionally
-take the lock for itself now.
-
-This fixes the 'block_resize' QMP command on a block node that runs in
-an iothread.
