Fixes a regression caused by 3008a6f21c.
Before the commit, when `mkdir_parents_internal()` is called from `mkdir_p()`,
it uses `_mkdir()` as `flag` is zero. But after the commit, `mkdir_safe_internal()`
is always used. Hence, if the path contains a symlink, it fails with -ENOTDIR.
To fix the issue, this makes `mkdir_p()` calls `mkdir_parents_internal()` with
MKDIR_FOLLOW_SYMLINK flag.
Fixes#22334.
Kernel commit dea2903719283c156b53741126228c4a1b40440f exposed (and
renamed) CIFS_MAGIC_NUMBER as CIFS_SUPER_MAGIC along with
SMB2_SUPER_MAGIC.
This fixes the following build fail on current Fedora Rawhide:
```
../src/basic/meson.build:389:8: ERROR: Problem encountered: found unknown filesystem(s) defined in kernel headers:
Filesystem found in kernel header but not in filesystems-gperf.gperf: CIFS_SUPER_MAGIC
Filesystem found in kernel header but not in filesystems-gperf.gperf: SMB2_SUPER_MAGIC
```
log_parse_environment() uses should_parse_proc_cmdline() to determine whether
it should parse settings from the kernel command line. But the checks that
should_parse_proc_cmdline() apply to the whole process, and we could get a positive
answer also when log_parse_environment() was called from one of the nss modules.
In case of nss-modules, we don't want to look at the kernel command line.
log_parse_environment_variables() that only looks at the environment variables
is split out and used in the nss modules.
Fixes#22020.
When the support for "synthetic errno" was added, we started truncating
the errno value to just the least significant byte. This is generally OK,
because errno values are defined up to ~130.
The docs don't really say what the maximum value is. But at least in principle
higher values could be added in the future. So let's stop truncating
the values needlessly.
The kernel (or libbpf?) have an error where they return 524 as an errno
value (https://bugzilla.redhat.com/show_bug.cgi?id=2036145). We would
confusingly truncate this to 12 (ENOMEM). It seems much nicer to let
strerror() give us "Unknown error 524" rather than to print the bogus
message about ENOMEM.
When chattr_full tries to apply flags one-by-one, and one fails,
record which errno was returned. But record EOPNOTSUPP(&friends)
only if no other error is observed, and return it only in that case
(otherwise keep returning ENOANO), so that callers can respond
appropriately to EOPNOTSUPP vs more relevant errors.
For example, this lets tmpfiles.d log at debug level when a filesystem
flag cannot be applied because the filesystem does not support it,
but at warning level if something else went wrong when applying it.
Restores logging behaviour of tmpfiles.d to pre-250.

This patch changes busctl capture to generate pcapng format
instead of the legacy pcap format files. It includes basic
meta-data in the file and still uses microsecond time
resolution. In future, more things can be added such as
high resolution timestams, statistics, etc.
PCAP Next Generation capture file format is what tshark uses
and is in process of being standardized in IETF. It is also
readable with libpcap.

In kernel's arch/parisc/include/uapi/asm/errno.h, ECANCELLED and
EREFUSED are defined as aliases of ECANCELED and ECONNREFUSED,
respectively. Let's drop them.

I think this makes it much easier to figure out what information sources
were used to generate the names, and why certain names were not generated.

The meson default for static_library() are:
build_by_default=true, install=false. We never interact with the
static libraries, and we only care about them as a stepping-stone towards
the installable executables or libraries. Thus let's only build them if
they are a dependency of something else we are building.
While at it, let's drop install:false, since this appears to be the default.
This change would have fixed the issue with lib_import_common failing
to build too: we wouldn't attempt to build it.
In practice this changes very little, because we generally only declare static
libraries where there's something in the default target that will make use of
them. But it seems to be a better pattern to set build_by_default to false.
The variable is not useful outside of the loop (it'll always be null
after the loop is finished), so we can declare it inline in the loop.
This saves one variable declaration and reduces the chances that somebody
tries to use the variable outside of the loop.
For consistency, 'de' is used everywhere for the var name.
On btrfs, trying to disable FS_NOCOW_FL on a file that has data
already written will fail silently without reporting an error. To
catch such cases, let's query the flags again if the IOC_SETFLAGS
ioctl() succeeds to make sure the flags we tried to configure we're
actually accepted by the kernel.
