Typically, the same client identifier setting is used for all
interfaces. Hence, better to provide the system-wide setting to specify
the client identifier.
Plus, linux/random.h never defined getrandom(), hence remove
the custom machinery for sys/random.h vs linux/random.h
in favor of single HAVE_GETRANDOM.
We assume its existence in basic/build-path.c, shared/userdb.c,
and coredump/coredump.c already, for which nothing has been reported
so far. So this seems safe to drop.
This turns systemd-ask-password into a small Varlink service, so that
there's an standard IPC way to ask for a password. It mostly directly
exposes the functionality of the Varlink service.
This new field allows specification of an fd on which the password
prompt logic will look for POLLHUP events for, and if seen will abort
the query.
The usecase for this is that when we query for a pw on behalf of a
Varlink client we can abort the query automatically if the client dies.
The current fallback path is actually unreliable, given
the kernel *supports* setting the resume offset through
cmdline after all, but just not exposed under /sys/.
For v258 let's drop it hence.
I didn't bump the baseline to 4.17, but merely documented
new requirement in README, because there's certainly more
compat stuff to drop between 4.3 and 4.17, and README is
a useful list for things to kill. We'll get to 5.4 eventually.
This also makes find_suitable_hibernation_device() report
more accurate error (ENOSPC -> ESTALE) if there's
no swap space on the system at all but resume= is set.
Fixes#35798
Replaces #35801
Fixes a bug caused by 804874d26a.
Follow-up for 084f361b50 and
a1417e5563.
Note, ERRNO_IS_NEG_DISCONNECT() includes ENONET rather than ENOENT...
So, ENOENT needs to be handled explicitly.
Fixes#35757 and #35806.
Prior to this commit, if no Exec*= is defined for socket,
and the unit was in SOCKET_FAILED state, failure of socket_open_fds()
would induce state transition SOCKET_FAILED -> SOCKET_FAILED,
and OnFailure= deps get unexpectedly skipped. Let's introduce
an intermediate state, so that during unit start we enter
UNIT_ACTIVATING at least once.
Fixes#35635
- Log about errors in socket_open_fds()
- Open parent dir fd and operate under it, instead of constructing paths
everywhere
- Replace scandir() with readdir_all()
