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] build: support explicitly disabling netcf
placing "-Dnetcf=disabled" on the meson commandline was ignored,
meaning that even with that option the build would get WITH_NETCF if
the netcf-devel package was found - the only way to disable it was to
uninstall netcf-devel.
This patch adds the small bit of logic to check the netcf meson
commandline option (in addition to whether netcf-devel is installed)
before defining WITH_NETCF.

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] qemuProcessRefreshDisks: Don't skip filling of disk
information if tray state didn't change
Content-type: text/plain
Commit 5ef2582646eb98 added emitting of even when refreshign disk state,
where it wanted to avoid sending the event if disk state didn't change.
This was achieved by using 'continue' in the loop filling the
information. Unfortunately this skips extraction of whether the device
has a tray which is propagated into internal structures, which in turn
broke cdrom media change as the code thought there's no tray for the
device.

The CURLOPT_PUT constant causes a deprecation warning when compiling on
Alpine Edge. The docs indicate it is deprecated since 7.2.1
https://curl.se/libcurl/c/CURLOPT_PUT.html
Since 7.87 the deprecation is now exposed at build time via a compiler
warning.
We already use CURLOPT_UPLOAD in the ESX driver, so this brings the CH
driver into line.

Subject: [PATCH] storage: Fix returning of locked objects from
'virStoragePoolObjListSearch'
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
CVE-2023-3750
'virStoragePoolObjListSearch' explicitly documents that it's returning
a pointer to a locked and ref'd pool that maches the lookup function.
This was not the case as in commit 0c4b391e2a9 (released in
libvirt-8.3.0) the code was accidentally converted to use 'VIR_LOCK_GUARD'
which auto-unlocked it when leaving the scope, even when the code was
originally "leaking" the lock.
Revert the corresponding conversion and add a comment that this function
is intentionally leaking a locked object.

Subject: [PATCH] virSetUIDGIDWithCaps: Don't drop CAP_SETPCAP right away
There are few cases where we execute a virCommand with all caps
cleared (virCommandClearCaps()). For instance
dnsmasqCapsRefreshInternal() does just that. This means, that
after fork() and before exec() the virSetUIDGIDWithCaps() is
called. But since the caller did not want to change anything,
just drop capabilities, these are the values of arguments:
virSetUIDGIDWithCaps (uid=-1, gid=-1, groups=0x0, ngroups=0,
capBits=0, clearExistingCaps=true)
This means that indeed all capabilities will be dropped,
including CAP_SETPCAP. But this capability controls whether
capabilities can be set, IOW whether capng_apply() succeeds.
There are two calls of capng_apply() in the function. The
CAP_SETPCAP is dropped after the first call and thus the other
call (capng_apply(CAPNG_SELECT_BOUNDS);) fails.
The solution is to keep the capability for as long as needed
(just like CAP_SETGID and CAP_SETUID) and drop it only at the
very end (just like CAP_SETGID and CAP_SETUID).

A process can access a file if the set of MCS categories
for the file is equal-to *or* a subset-of, the set of
MCS categories for the process.
If there are two VMs:
a) svirt_t:s0:c117
b) svirt_t:s0:c117,c720
Then VM (b) is able to access files labelled for VM (a).
IOW, we must discard case where the categories are equal
because that is a subset of many other valid category pairs.

Subject: [PATCH] virSetUIDGIDWithCaps: Set bounding capabilities only with
CAP_SETPCAP
In one of my previous patches I've tried to postpone dropping
CAP_SETPCAP until the very end because it's needed for
capng_apply(). What I did not realize back then was that we might
not have the capability to begin with. Because of unknown reasons
capng_apply() pollutes logs only for CAPNG_SELECT_BOUNDS and not
for CAPNG_SELECT_CAPS.
Reproducer is really simple: run libvirtd as a regular user.
During its initialization, libvirtd will spawn some binaries
(dnsmasq, qemu-*, etc.) and while doing so it will try to drop
capabilities.
Anyway, let's call capng_apply(CAPNG_SELECT_BOUNDS) only if we
have the CAP_SETPCAP (which is tracked in need_setpcap variable).

Subject: [PATCH] qemu_firmware: don't error out for unknown firmware features
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
When QEMU introduces new firmware features libvirt will fail until we
list that feature in our code as well which doesn't sound right.
We should simply ignore the new feature until we add a proper support
for it.

Subject: [PATCH 1/2] wireshark: Switch to tvb_bytes_to_str()
When the dissector sees a byte sequence that is either an opaque
data (xdr_opaque) or a byte sequence (xdr_bytes) it formats the
bytes as a hex numbers using our own implementation. But
wireshark already provides a function for it: tvb_bytes_to_str().
NB, the reason why it returns a const string is so that callers
don't try to free it - the string is allocated using an allocator
which will decide when to free it.
The wireshark formatter was introduced in wireshark commit of
v1.99.2~479 and thus is present in the version we require at
least (2.6.0).

Subject: [PATCH 2/2] wireshark: Drop needless comment in dissect_xdr_bytes()
In the dissect_xdr_bytes() there's a comment that the string
allocated by xdr_bytes() can't be freed using xdr_free(). Well,
that is expected because xdr_bytes() used plain calloc() AND the
string is not an XDR struct but plain 'char *' type. Passing it
to xdr_free() must result in weird things happening.
