[PATCH] virsh: Simplify @flags handing in cmdSetmem() and cmdSetmaxmem()
by Michal Privoznik
What code tries to achieve is that if no flags were provided to
either 'setmem' or 'setmaxmem' commands then the old (no flags)
API is called to be able to communicate with older daemons.
Well, the code can be simplified a bit.
Note that with this change the old no flag version of APIs is
used more often. Previously if --current argument was given it
resulted in *Flags() version to be called even though it is not
necessary - VIR_DOMAIN_AFFECT_CURRENT is implied.
Therefore, this change in fact allows virsh to talk with broader
set of daemons.

[PATCH v2] docs: Clarify the documentation of the <css> elements
by Thomas Huth
The channel subsystem elements describe a channel in the I/O subsystem
of a s390x machine, and not a normal device (like a disk or network card).
Reword the documentation here to make it this a little bit clearer.

[PATCH] virfile: workaround for when posix_fallocate() is not supported by FS
by Roman Bogorodskiy
posix_fallocate() might be not supported by a filesystem, for example,
it's not supported by ZFS. In that case it fails with
return code 22 (EINVAL), and thus safezero_posix_fallocate() returns -1.
As safezero_posix_fallocate() is the first function tried by safezero()
and it tries other functions only when it returns -2, it fails
immediately without falling back to other methods, such as
safezero_slow().
Fix that by returning -2 if posix_fallocate() returns EINVAL, to give
safezero() a chance to try other functions.

[libvirt PATCH 00/19] Overhaul test/commandhelper.c
by Tim Wiederhake
I stumbled upon a buffer overflow / stack smash present in
"test/commandhelper.c" that could be triggered by e.g.
$ ./tests/commandhelper --readfd 0 --readfd 0 --readfd 0 --readfd x
Could not parse fd x
*** stack smashing detected ***: terminated
Aborted (core dumped)
This series cleans up the file, fixes the buffer overflow and converts
(most) memory handling to g_auto*.
Note that it does not touch the "prevent malloc with zero size" issue
discussed in
https://www.redhat.com/archives/libvir-list/2021-January/msg01160.html,
this will be done in the other series.
Please feel free to comment on whether the copyright year in the file's
header should be updated and whether a prefix for the function names
and the new type is required.
Cheers,
Tim

[libvirt PATCH v2 0/2] stop using netcf for the interface driver backend
by Laine Stump
V1 here: https://www.redhat.com/archives/libvir-list/2021-January/msg00922.html
A short version of the cover letter from V1: this is a followup to my
proposal to stop using netcf for the interface driver backend in
Fedora/RHEL/CentOS builds and use the udev backend instead (it turns
out Ubuntu already disabled netcf in 2018).
Changes in V2:
* removed the patch that made the default netcf=disabled even when
netcf-devel was found on the host. If someone has netcf-devel
installed and still wants to build without netcf, then can add
"-Dnetcf=disabled" on the meson commandline.
* Made the specfile changes more intelligent:
* instead of hardcoding -Dnetcf=disabled, we now have a variable
%{with_netcf} that is set to 1 for current Fedora (< 34) and current
RHEL (< 9) but will be set to 0 for future Fedora/RHEL. This way the
behavior on current OS releases will remain the same even for future
libvirt.
* it is possible to for netcf support off even in current/older OS
releases by adding "--without netcf" to the rpmbuild commandline.
I think at this point I would be comfortable pushing these patches, unless someone has misgivings about it...
Laine Stump (2):
build: support explicitly disabling netcf
rpm: disable netcf for the interface driver in rpm build on new
targets
