This effectively disables warnings about type/mode/ownership of existing
directories when recursively creating parent directories. (Or files. If there's
a file in a place we expect a directory, the code will later try to create
a file and fail. This follows the general pattern where we do (void)mkdir()
if the mkdir() is immediately followed by opening of a file.)
I was recently debugging an issue with the fstab-generator [1], and it says:
'Directory "/tmp" already exists, but has mode 0777 that is too permissive (0644 was requested), refusing.'
which is very specific but totally wrong in this context.
This output was added in 37c1d5e97d, and I still
think it is worth to do it, because if you actually *do* want the directory, if
there's something wrong, the precise error message will make it much easier to
diagnose. And we can't easily pass the information what failed up the call chain
because there are multiple things we check (ownership, permission mask, type)…
So passing a param whether to warn or not down into the library code seems like
the best solution, despite not being very elegant.

when they go down resolved prints
```
Event source mdns-ipv4 (type io) returned error, disabling
```
instead of
```
Event source n/a (type io) returned error, disabling
```
Even though ISO C11 doesn't mandate in which order the type specifiers
should appear, having `unsigned` at the beginning of each type
declaration feels more natural and, more importantly, it unbreaks
Coccinelle, which has a hard time parsing `long unsigned` and others:
```
init_defs_builtins: /usr/lib64/coccinelle/standard.h
init_defs: /home/mrc0mmand/repos/systemd/coccinelle/macros.h
HANDLING: src/shared/mount-util.c
: 1: strange type1, maybe because of weird order: long unsigned
```
Most of the codebase already "complies", so let's fix the remaining
"offenders".
Every time I need it I have to first relearn autopkgtest and find where
all the necessary stuff lives, so let's document it somewhere close to
systemd for (at least) future me.
Try to ensure kernel IPv6 link local address generation occurs by
setting the per-if addr_gen_mode sysctl when the link is already up,
instead of the netlink interface (IFLA_INET6_ADDR_GEN_MODE).
The netlink setting is sufficient in cases where the interface is not
yet up when networkd configures an interface - bringing the interface
up will trigger in-kernel address generation.
If the interface is already up, yet the interface has no IPv6LL assigned
setting IFLA_INET6_ADDR_GEN_MODE has no effect.
Writing the addr_gen_mode sysctl is a best effort attempt at triggering
address generation regardless of interface state because it also works
in cases where the interface is already up.
Fixes#22424.
In cbcdcaaa0e ("Add support for conditions on the machines firmware")
a new Firmware= directive was added for .netdev and .network files.
While it was also documented to work on .link files, in actual fact the
support was missing. Add that one extra line to make it work, and also
update the fuzzer directives.
ERROR:
Cannot use target systemd as a generator because it is built for the
host machine and no exe wrapper is defined or needs_exe_wrapper is
true. You might want to set `native: true` instead to build it for
the build machine.
Judging by
ERROR! Failed to call GitHub Status API!
it doesn't seem to work. Even if it did it would just clutter the status
checks I think so let's just remove MULTI_STATUS along with
GITHUB_TOKEN.
This helper is just like config_parse_string() but does some superficial
checks for control characters and quotes.
In most cases we currently use config_parse_string() we probably want to
use config_parse_safe_string() for safety reasons.
Add the "Isolated" parameter in the *.network file, e.g.,
[Bridge]
Isolated=true|false
When the Isolated parameter is true, traffic coming out of this port
will only be forward to other ports whose Isolated parameter is false.
When Isolated is not specified, the port uses the kernel default
setting (false).
The "Isolated" parameter was introduced in Linux 4.19.
See man bridge(8) for more details.
But even though the kernel and bridge/iproute2 recognize the "Isolated"
parameter, systemd-networkd did not have a way to set it.
some actions like Coverity and CFLite aren't run on every PR so to make
sure they are more or less fine when they are changed it makes sense to
at least check them with superlinter/actionlint: https://github.com/rhysd/actionlint
The following warnings were fixed along the way:
