everywhere: port everything to sigprocmask_many() and friends
|
|
automatically remove old machine shapshots at boot
|
|
This ports a lot of manual code over to sigprocmask_many() and friends.
Also, we now consistly check for sigprocmask() failures with
assert_se(), since the call cannot realistically fail unless there's a
programming error.
Also encloses a few sd_event_add_signal() calls with (void) when we
ignore the return values for it knowingly.

buildsys: missing SECCOMP_CFLAGS in various places
|
|
Remove old temporary snapshots, but only at boot. Ideally we'd have
"self-destroying" btrfs snapshots that go away if the last last
reference to it does. To mimic a scheme like this at least remove the
old snapshots on fresh boots, where we know they cannot be referenced
anymore. Note that we actually remove all temporary files in
/var/lib/machines/ at boot, which should be safe since the directory has
defined semantics. In the root directory (where systemd-nspawn
--ephemeral places snapshots) we are more strict, to avoid removing
unrelated temporary files.
This also splits out nspawn/container related tmpfiles bits into a new
tmpfiles snippet to systemd-nspawn.conf
|
|
|
|
This adds a "char *extra" parameter to tempfn_xxxxxx(), tempfn_random(),
tempfn_ranomd_child(). If non-NULL this string is included in the middle
of the newly created file name. This is useful for being able to
distuingish the kind of temporary file when we see one.
This also adds tests for the three call.
For now, we don't make use of this at all, but port all users over.

libcore, systemd and nspawn fail to build when seccomp headers
are not in the include path.

just created
We already had a safety check in place that we don't end up descending
to the original subvolume again, but we also should avoid descending in
the newly created one.
This is particularly important if we make a snapshot below its source,
like we do in "systemd-nspawn --ephemeral -D /".

The names fw-util.[ch] are too ambiguous, better rename the files to
firewall-util.[ch]. Also rename the test accordingly.

nspawn: make seccomp loading errors non-fatal
|
|
|
|
seccomp_load returns -EINVAL when seccomp support is not enabled in the
kernel [1]. This should be a debug log, not an error that interrupts nspawn.
If the seccomp filter can't be set and audit is enabled, the user will
get an error message anyway.

Fix CID 1304686: Dereference after null check (FORWARD_NULL)
However, this commit does not fix any bug in logind. It helps to keep
the elect_display_compare() function generic.
|
|
Set $SYSTEMD_LOG_TARGET so that the output always goes to stdout/stderr. This
fixes running the test as root, as that logged to the journal previously.

test-netlink-manual: typo fix

Currently, the HASHMAP iterators stop at the first NULL entry in a
hashmap. This is non-obvious and breaks users like sd-device, which
legitimately store NULL values in a hashmap.
Fix all the iterators by taking a pointer to the value storage, instead of
returning it. The iterators now return a boolean that tells whether the
end of the list was reached.
Current users of HASHMAP_FOREACH() are *NOT* changed to explicitly check
for NULL. If it turns out, there were users that inserted NULL into
hashmaps, but didn't properly check for it during iteration, then we
really want to find those and fix them.

If you use bus_map_all_properties(), you must be aware that it might
touch output variables even though it may fail. This is, because we parse
many different bus-properties and cannot tell how to clean them up, in
case we fail deep down in the parser.
Fix all callers of bus_map_all_properties() to correctly cleanup any
context structures at all times.

Unplugging and plugging in the cable will create various scancodes
on the keyboard controller.
Userspace within X should be able to interact with these to show
interesting messages. Assign them to generic prog1/prog2.
(David: add comment to hwdb explaining that these keycodes are reserved)

We do not support '/run' for hwdb files. Drop it from the man-pages so
people don't accidentally use it.

No functional change, but looked weird.

Improve the documentation of bus credentials by mentioning send-time metadata. This needs more love, we should really clarify metadata details here. However, this is still better than nothing, so it's fine.

Improve tun/tap logging by using the new log_*errno*() functions that set 'errno' explicitly. Also fix a bunch of incorrect errno/r confusions.
