Zbigniew Jędrzejewski-Szmek a412ec5714 meson: fix git ls-files invocations during rebase
Normally ls-files prints the full path to files from the repo root. But when
$GIT_WORK_TREE is set, ls-files prints paths relative to the current
directory. When rebasing, $GIT_WORK_TREE is set in the commands executed from
'rebase -x'. This causes problems if meson config is touched and the meson
reconfigures itself. ($GIT_WORK_TREE shouldn't be relevant, since the paths that
ls-files reports don't depend on the work tree, but whatever.) Let's unset
GIT_WORK_TREE to avoid the issue.

$ (cd test; git --git-dir=$PWD/../.git ls-files ':/test/dmidecode-dumps/*.bin')
test/dmidecode-dumps/HP-Z600.bin
test/dmidecode-dumps/Lenovo-ThinkPad-X280.bin
test/dmidecode-dumps/Lenovo-Thinkcentre-m720s.bin

$ (cd test; GIT_WORK_TREE=$PWD/.. git --git-dir=$PWD/../.git ls-files ':/test/dmidecode-dumps/*.bin')
dmidecode-dumps/HP-Z600.bin
dmidecode-dumps/Lenovo-ThinkPad-X280.bin
dmidecode-dumps/Lenovo-Thinkcentre-m720s.bin

Fixes #18148.

Ulrich Ölmann 77b674049b network: can: add support for bus error reporting
Enhance systemd-networkd to be able to control a CAN device's berr-reporting
flag via the new boolean directive BusErrorReporting= to be used in network
files.

Yu Watanabe ae45e1a383 resolve: slightly optimize dns_answer_add()
Previously, dns_answer_add() was O(n^2).
With this change dns_packet_extract() becomes ~15 times faster for some
extremal case.

Before:
```
$ time ./fuzz-dns-packet ~/downloads/clusterfuzz-testcase-minimized-fuzz-dns-packet-5631106733047808
/home/watanabe/downloads/clusterfuzz-testcase-minimized-fuzz-dns-packet-5631106733047808... ok

real    0m15.453s
user    0m15.430s
sys     0m0.007s
```

After:
```
$ time ./fuzz-dns-packet ~/downloads/clusterfuzz-testcase-minimized-fuzz-dns-packet-5631106733047808
/home/watanabe/downloads/clusterfuzz-testcase-minimized-fuzz-dns-packet-5631106733047808... ok

real    0m0.831s
user    0m0.824s
sys     0m0.006s
```

Hopefully fixes oss-fuzz#19227.

Devon Pringle 16c89e649d networkd: add RouteDenyList
Allow configuration for IPv6 discovered routes to be ignored instead of
adding them as a route. This can be used to block unwanted routes, for
example, you may wish to not receive some set of routes on an interface
if they are causing issues.

Kristijan Gjoshev acf24a1a84 timer: add new feature FixedRandomDelay=
FixedRandomDelay=yes will use
`siphash24(sd_id128_get_machine() || MANAGER_IS_SYSTEM(m) || getuid() || u->id)`,
where || is concatenation, instead of a random number to choose a value between
0 and RandomizedDelaySec= as the timer delay.
This essentially sets up a fixed, but seemingly random, offset for each timer
iteration rather than having a random offset recalculated each time it fires.

Closes #10355

Lennart Poettering 4e39995371 core: introduce ProtectProc= and ProcSubset= to expose hidepid= and subset= procfs mount options
Kernel 5.8 gained a hidepid= implementation that is truly per procfs,
which allows us to mount a distinct once into every unit, with
individual hidepid= settings. Let's expose this via two new settings:
ProtectProc= (wrapping hidpid=) and ProcSubset= (wrapping subset=).

Lennart Poettering 476cfe626d core: remove support for ConditionNull=

It has been deprecated since 90a2ec10f2 (6
years ago) and we started to warn since
55dadc5c57 (1.5 years ago).

Let's get rid of it altogether.

Alvin Šipraga 0d0de133f0 network: add support for MACVLAN source mode
Add support for creating a MACVLAN interface in "source" mode by
specifying Mode=source in the [MACVLAN] section of a .netdev file.

A list of allowed MAC addresses for the corresponding MACVLAN can also
be specified with the SourceMACAddress= option of the [MACVLAN] section.

An example .netdev file:

    [NetDev]
    Name=macvlan0
    Kind=macvlan
    MACAddress=02:DE:AD:BE:EF:00

    [MACVLAN]
    Mode=source
    SourceMACAddress=02:AB:AB:AB:AB:01 02:CD:CD:CD:CD:01
    SourceMACAddress=02:EF:EF:EF:EF:01

The same keys can also be specified in [MACVTAP] for MACVTAP kinds of
interfaces, with the same semantics.

Zbigniew Jędrzejewski-Szmek d1ca1f7c2a xdg-autostart: avoid quadratic behaviour in strv parsing
The fuzzer test case has a giant line with ";;;;;;;;;;;..." which is turned into
a strv of empty strings. Unfortunately, when pushing each string, strv_push() needs
to walk the whole array, which leads to quadratic behaviour. So let's use
greedy_allocation here and also keep location in the string to avoid iterating.

Fixes https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=22812.

Other minor changes:
- say "was already defined" instead of "defined multiple times" to make it
  clear that we're ignoring this second definition, and not all definitions
  of the key
- unescaping needs to be done also for the last entry

Susant Sahani 518cd6b527 network: Introduce SR-IOV
SR-IOV provides the ability to partition a single physical PCI
resource into virtual PCI functions which can then be injected in
to a VM. In the case of network VFs, SR-IOV improves north-south n
etwork performance (that is, traffic with endpoints outside the
host machine) by allowing traffic to bypass the host machine’s network stack.
