Mike Yuan 78b47a4e89 xattr-util: drop unnecessary nofollow normalization 
Follow-up for b8df25dcfe

This is some leftover from get/listxattrat() usage which
got dropped later.

Mike Yuan 63ed611579 string-util: modernize strextendn() a bit 
l == SIZE_MAX requires no special handling, since we assert
on (s || l == 0) above.

Michael Olbrich e91c5cf06a missing_sched: add CLONE_PIDFD 
CLONE_PIDFD was introduced in v5.2 and in sched.h in glibc-2.31 so
without this, building with older version fails with:

src/basic/raw-clone.h:41:108: error: 'CLONE_PIDFD' undeclared (first use in this function); did you mean 'CLONE_FILES'?

Mike Yuan b8df25dcfe xattr-util: try new *xattrat() family syscalls first 
Added in https://github.com/torvalds/linux/commit/6140be90ec70c39fa844741ca3cc807dd0866394

However, when O_PATH fds are encountered we'd have to go by
/proc/self/fd/ still, since the kernel people are reluctant
to make the new syscalls work with them
(https://lore.kernel.org/linux-fsdevel/20250206-steril-raumplanung-733224062432@brauner/)
Hence getxattrat() and listxattrat() are not employed.

While at it, remove the discrepancy between path being NULL
and empty - I don't grok the "security issue" claimed earlier,
but nowadays even the kernel treats the two as identical:

Mike Yuan daf1320237 terminal-util: make get_kernel_consoles() return > 0 if /dev/console is resolved 2025-01-26 04:15:41 +01:00
Mike Yuan b27f791691 terminal-util: stop doing 0/upper bound check in tty_is_vc() 
tty_is_vc() is more often than not used for simple "categorization"
than validity check. E.g. in logind, we first recognize the tty
"looks like vc", and then use vtnr_from_tty() where range check
is performed and vtnr is extracted. In such cases, we want to reject
invalid vtnr from clients rather than silently carry on, hence
let's remove bound check in tty_is_vc().

Fixes #36166
Replaces #36167 and #36175

Lennart Poettering d15811d7e5 devnum-util: add macros to safely convert dev_t to pointers and back 
Sometimes it's nice being able to store dev_t as pointer values in
hashmaps/tables, instead of having to allocate memory for them and using
devt_hash_ops. After all dev_t is weird on Linux/glibc: glibc defines it
as 64bit entity (which hence appears as something we cannot encode in a
pointer value for compat with 32bit archs) but it actually is 32bit in
the kernel apis. Hence we can safely cut off the upper 32bit, and still
retain compat with all archs.

But let's hide this in new macros, and validate this is all correct via
a test.

Yu Watanabe 90cf374e45 run: add --job-mode= argument (#34708) 
systemctl has a --job-mode= argument, and adding the same argument to
systemd-run is useful for starting transient scopes with dependencies.
For example, if a transient scope BindsTo a service that is stopping,
specifying --job-mode=replace will wait for the service to stop before
starting it again, while the default job mode of "fail" will cause the
systemd-run invocation to fail.

Mike Yuan 7ce2c1bb5f mountpoint-util: rename fd_is_mount_point() to is_mount_point_at() 
fd_* functions in our codebase usually mean fd-specific operations,
while this one actually takes openat()-style params. Rename it
accordingly hence.

Mike Yuan e2f97c790e mountpoint-util: some tweaks for fd_is_mount_point()

- Accept fd being AT_FDCWD and filename being "."

Lennart Poettering 36a2be13c4 random-util: include pidfdid in fallback RNG buffer 
This doesn't make the RNG cryptographic strength, but if we have it
easily accessible, why not include the pidfd id. It is after all not
vulnerable to reuse.
