Subject: [PATCH] Fix off-by-one error in udevListInterfacesByStatus
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Ever since this function was introduced in 2012 it could've tried
filling in an extra interface name. That was made worse in 2019 when
the caller functions started accepting NULL arrays of size 0.
This is assigned CVE-2024-1441.

Subject: [PATCH] interface: fix udev_device_get_sysattr_value return value
check
Reviewing the code I found that return value of function
udev_device_get_sysattr_value() is dereferenced without a check.
udev_device_get_sysattr_value() may return NULL by number of reasons.
v2: VIR_DEBUG added, replaced STREQ(NULLSTR()) with STREQ_NULLABLE()
v3: More checks added, to skip earlier. More verbose VIR_DEBUG.

Subject: [PATCH] rpc: avoid leak of GSource in use for interrupting main loop
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
We never release the reference on the GSource created for
interrupting the main loop, nor do we remove it from the
main context if our thread is woken up prior to the wakeup
callback firing.
This can result in a leak of GSource objects, along with an
ever growing list of GSources attached to the main context,
which will gradually slow down execution of the loop, as
several operations are O(N) for the number of attached GSource
objects.

The root cause is a bad assumption in the virNetClientIOEventLoop
method. This method is run by whichever thread currently owns the
buck, and is responsible for handling I/O. Inside a for(;;) loop,
this method creates a temporary GSource, adds it to the event loop
and runs g_main_loop_run(). When I/O is ready, the GSource callback
(virNetClientIOEventFD) will fire and call g_main_loop_quit(), and
return G_SOURCE_REMOVE which results in the temporary GSource being
destroyed. A g_autoptr() will then remove the last reference.
What was overlooked, is that a second thread can come along and
while it can't enter virNetClientIOEventLoop, it will register an
idle source that uses virNetClientIOWakeup to interrupt the
original thread's 'g_main_loop_run' call. When this happens the
virNetClientIOEventFD callback never runs, and so the temporary
GSource is not destroyed. The g_autoptr() will remove a reference,
but by virtue of still being attached to the event context, there
is an extra reference held causing GSource to be leaked. The
next time 'g_main_loop_run' is called, the original GSource will
trigger its callback, and access data that was allocated on the
stack by the previous thread, and likely SEGV.
To solve this, the thread calling 'g_main_loop_run' must call
g_source_destroy, immediately upon return, to guarantee that
the temporary GSource is removed.

Subject: [PATCH] rpc: fix race in waking up client event loop
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
The first thread to issue a client RPC request will own the event
loop execution, sitting in the virNetClientIOEventLoop function.
It releases the client lock while running:
virNetClientUnlock()
g_main_loop_run()
virNetClientLock()
If a second thread arrives with an RPC request, it will queue it
for the first thread to process. To inform the first thread that
there's a new request it calls g_main_loop_quit() to break it out
of the main loop.
This works if the first thread is in g_main_loop_run() at that
time. There is a small window of opportunity, however, where
the first thread has released the client lock, but not yet got
into g_main_loop_run(). If that happens, the wakeup from the
second thread is lost.
This patch deals with that by changing the way the wakeup is
performed. Instead of directly calling g_main_loop_quit(), the
second thread creates an idle source to run the quit function
from within the first thread. This guarantees that the first
thread will see the wakeup.

Subject: [PATCH] tests: force use of "NORMAL" TLS priority in test suite
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
When generating certificates we rely on GNUTLS' built-in default setup
for the ciphers used in the certs. We then currently run with the distro
specific TLS priority setup which can be much stronger, to the extent
that the certificates we generate are considered untrustworthy. We don't
care about the quality of the ciphers we use in the test suite, so just
force the priority to "NORMAL" which should ensure our certs are
accepted by GNUTLS.

Subject: [PATCH] cpu: define the 'virt-ssbd' CPUID feature bit (CVE-2018-3639)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Some AMD processors only support a non-architectural means of
enabling Speculative Store Bypass Disable. To allow simplified
handling in virtual environments, hypervisors will expose an
architectural definition through CPUID bit 0x80000008_EBX[25].
This needs to be exposed to guest OS running on AMD x86 hosts to
allow them to protect against CVE-2018-3639.
Note that since this CPUID bit won't be present in the host CPUID
results on physical hosts, it will not be enabled automatically
in guests configured with "host-model" CPU unless using QEMU
version >= 2.9.0. Thus for older versions of QEMU, this feature
must be manually enabled using policy=force. Guests using the
"host-passthrough" CPU mode do not need special handling.

Subject: [PATCH] nwfilter: increase pcap buffer size to be compatible with
TPACKET_V3
When an nwfilter rule sets the parameter CTRL_IP_LEARNING to "dhcp",
this turns on the "dhcpsnoop" thread, which uses libpcap to monitor
traffic on the domain's tap device and extract the IP address from the
DHCP response.
If libpcap on the host is built with HAVE_TPACKET3 defined (to enable
support for TPACKET_V3), the dhcpsnoop code's initialization of the
libpcap socket would fail with the following error:
virNWFilterSnoopDHCPOpen:1134 : internal error: pcap_setfilter: can't remove kernel filter: Bad file descriptor
It turns out that this was because TPACKET_V3 requires a larger buffer
size than libvirt was setting (we were setting it to 128k). Changing
the buffer size to 256k eliminates the error, and the dhcpsnoop thread
once again works properly.
A fuller explanation of why TPACKET_V3 requires such a large buffer,
for future git spelunkers:
libpcap calls setsockopt(... SOL_PACKET, PACKET_RX_RING...) to setup a
ring buffer for receiving packets; two of the attributes sent to this
API are called tp_frame_size, and tp_frame_nr. If libpcap was built
with HAVE_TPACKET3 defined, tp_trame_size is set to MAXIMUM_SNAPLEN
(defined in libpcap sources as 262144) and tp_frame_nr is set to:
[the buffer size we set, i.e. PCAP_BUFFERSIZE i.e. 262144] / tp_frame_size.
So if PCAP_BUFFERSIZE < MAXIMUM_SNAPLEN, then tp_frame_nr (the number
of frames in the ring buffer) is 0, which is nonsensical. This same
value is later used as a multiplier to determine the size for a call
to malloc() (which would also fail).
(NB: if HAVE_TPACKET3 is *not* defined, then tp_frame_size is set to
the snaplen set by the user (in our case 576) plus a small amount to
account for ethernet headers, so 256k is far more than adequate)
Since the TPACKET_V3 code in libpcap actually reads multiple packets
into each frame, it's not a problem to have only a single frame
(especially when we are monitoring such infrequent traffic), so it's
okay to set this relatively small buffer size (in comparison to the
default, which is 2MB), which is important since every guest using
dhcp snooping in a nwfilter rule will hold 2 of these buffers for the
entire life of the guest.
Thanks to Christian Ehrhardt for discovering that buffer size was the
problem (this was not at all obvious from the error that was logged!)

Subject: [PATCH] util: don't check for parallel iteration in hash-related
functions
This is the responsability of the caller to apply the correct lock
before using these functions. Moreover, the use of a simple boolean
was still racy: two threads may check the boolean and "lock" it
simultaneously.
Users of functions from src/util/virhash.c have to be checked for
correctness. Lookups and iteration should hold a RO
lock. Modifications should hold a RW lock.
Most important uses seem to be covered. Callers have now a greater
responsability, notably the ability to execute some operations while
iterating were reliably forbidden before are now accepted.

Subject: [PATCH] esx: Fix double-free and freeing static strings in
esxDomainSetAutostart
Since commit ae83e02f3dd7fe99fed5d8159a35b666fafeafd5#l3393 the
newPowerInfo pointer itself is used to track the ownership of the
AutoStartPowerInfo object to make Coverity understand the code better.
This broke the code that unset some members of the AutoStartPowerInfo
object that should not be freed the normal way.
Instead, transfer ownership of the AutoStartPowerInfo object to the
HostAutoStartManagerConfig object before filling in the values that
need special handling. This allows to free the AutoStartPowerInfo
directly without having to deal with the special values, or to let
the old (now restored) logic handle the special values again.

The microcode version checks are used to invalidate cached CPU data we
get from QEMU. To minimize /proc/cpuinfo parsing the microcode version
was only read when libvirtd started and cached for the daemon's
lifetime. However, the CPU microcode can change anytime (updating the
microcode package can automatically upload it to the CPU) and we need to
stop caching it to avoid using stale CPU model data.

be46f61326 made the situation even worse since libvirt would report
correct microcode version while still using the old host CPU model
(visible in domain capabilities XML).

current UID
MIME-Version: 1.0

The admin protocol RPC messages are only intended for use by the user
running the daemon. As such they should not be allowed for any client
UID that does not match the server UID.

Subject: [PATCH 2/3] locking: restrict sockets to mode 0600
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
The virtlockd daemon's only intended client is the libvirtd daemon. As
such it should never allow clients from other user accounts to connect.
The code already enforces this and drops clients from other UIDs, but
we can get earlier (and thus stronger) protection against DoS by setting
the socket permissions to 0600

Subject: [PATCH] conf: Restore setting default bus for input devices
Prior to v9.3.0-rc1~30 we used to set default bus for <input/>
devices, during XML parsing. In the commit this code was moved to
a post parse callback. But somehow the line that sets the bus in
one specific case disappeared. Bring it back.
