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] virdevmapper: Don't cache device-mapper major
The device mapper major is needed in virIsDevMapperDevice() which
determines whether given device is managed by device-mapper. This
number is obtained by parsing /proc/devices and then stored in a
global variable so that the file doesn't have to be parsed again.
However, as it turns out this logic is flawed - the major number
is not static and can change as it can be specified as a
parameter when loading the dm-mod module.
Unfortunately, I was not able to come up with a good solution and
thus the /proc/devices file is being parsed every time we need
the device mapper major.

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).

Subject: [PATCH] virdevmapper: Handle kernel without device-mapper support
In one of my latest patch (v6.6.0~30) I was trying to remove
libdevmapper use in favor of our own implementation. However, the
code did not take into account that device mapper can be not
compiled into the kernel (e.g. be a separate module that's not
loaded) in which case /proc/devices won't have the device-mapper
major number and thus virDevMapperGetTargets() and/or
virIsDevMapperDevice() fails.
However, such failure is safe to ignore, because if device mapper
is missing then there can't be any multipath devices and thus we
don't need to allow the deps in CGroups, nor create them in the
domain private namespace, etc.

A process can access a file if the set of MCS categories

If there are two VMs:
a) svirt_t:s0:c117

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] virdevmapper: Ignore all errors when opening
/dev/mapper/control
So far, only ENOENT is ignored (to deal with kernels without
devmapper). However, as reported on the list, under certain
scenarios a different error can occur. For instance, when libvirt
is running inside a container which doesn't have permissions to
talk to the devmapper. If this is the case, then open() returns
-1 and sets errno=EPERM.
Assuming that multipath devices are fairly narrow use case and
using them in a restricted container is even more narrow the best
fix seems to be to ignore all open errors BUT produce a warning
on failure. To avoid flooding logs with warnings on kernels
without devmapper the level is reduced to a plain debug message.

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).

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] node_device: Use "udev" monitor source
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
In v6.3.0-rc1~67 I've made a switch: instead of listening on udev
events the nodedev driver started listening for kernel events.
This was because when a device changes its name (e.g. NICs) we
will get "move" event with DEVPATH_OLD property set, which we can
then use to remove the old device and thus keep our internal list
up to date. The switch to "kernel" source was made because if the
old NICs naming (eth0, eth1, ...) is enabled (e.g. via
net.ifnames=0 on the kernel cmd line) then udev overwrites the
property with the new name making our internal list go out of
sync. Interestingly, when the od NICs naming is not enabled then
the DEVPATH_OLD contains the correct value.
But as it turns out, "kernel" source might be missing some other
important properties, e.g. USB vendor/product IDs. Therefore,
switch back to "udev" source and wish the best of luck to users
using the old NICs naming.

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).

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.
