Since commit 36c16a7cdd ("core: rework unit timeout handling, and add
new setting RuntimeMaxSec=") TimeoutSec=0 in mount units has
cause the mount to timeout immediately instead of never as documented.
There is a similar problem with Socket.TimeoutSec and Swap.TimeoutSec.
These are easily fixed using config_parse_sec_fix_0().
Automount.TimeoutIdleSec looks like it could have the same problem,
but doesn't because the kernel treats '0' as 'no timeout'.
It handle USEC_INFINITY correctly only because that constant has
the value '-1', and when round up, it becomes zero.
To avoid possible confusion, use config_parse_sec_fix_0() as well, and
explicitly handle USEC_INFINITY.
When automatic /tmp mount was introduced to nspawn in v219, it was done without having the nosuid and nodev mount options, which was the same case as systemd's default tmp.mount unit back then.
nosuid and nodev was added to tmp.mount(.m4) in v231 for security reasons. matching the nspawn /tmp mount entry against that.

LLDP should be received on bridge slaves as they're the entities
directly connected to a peer. Receiving LLDP on the bridge device makes
little sense, Linux by default even filters out LLDP going onto the
bridge device.
Flip the current logic, receive LLDP on bridge slaves don't listen for
them on the bridge itself.
Let's log about this in the caller.
Doesn't really matter, but let's do something about my OCD, and
propagate errors properly, so that the caller can log about them.
Let's downgrade the warning introduced by
955d99edc7 to debug, as we really
shouldn't log at more than debug level from library code.
(And while we are at it, print the MTU as the right (unsigned) type in
the format string.)
unit_name_template returns -EINVAL if the unit name is not a template, but
the code assumed that OOM is the only failure mode. Fix that to emit the warning
if a non-template unit is encountered (because in this case we expect the name
to match exactly), and just skip the warning on other errors (presumably oom).
Fixes#5543.
DHCP responses could include static routes, but unfortunately not an
option to tell what scope to use. So it's important that the client sets
it properly.
This mimics what the `ip route add` command does when adding a static
route without an explicit scope:
* If the destination IP is on the local host, use scope `host`
* Otherwise if the gateway IP is null (direct route), use scope `link`
* If anything else, use the current default `global`.
Fixes#5979.
*scanf functions set errno on i/o error. For sscanf, this doesn't really apply,
so (based on the man page), it seems that errno is unlikely to be ever set to a
useful value. So just ignore errno. The error message includes the string that
was parsed, so it should be always pretty clear why parsing failed.
On the other hand, detect trailing characters and minus prefix that weren't
converted properly. This matches what our safe_ato* functions do. Add tests to
elucidate various edge cases.
All those uses were correct, but I think it's better to be explicit.
Using implicit errno is too error prone, and with this change we can require
(in the sense of a style guideline) that the code is always specified.
Helpful query: git grep -n -P 'log_[^s][a-z]+\(.*%m'
MESSAGE=data\n and MESSAGE\n40000000data\n are both valid serializations, so
they should be stored in the journal. Before, MESSAGE, SYSLOG_FACILITY,
SYSLOG_IDENTIFIER, PRIORITY, and OBJECT_PID would be only honoured if they were
given in the first form.
Fixed#5973.
For all except the last entry in a single packet, we would dispatch the
message to the journal, but not forward it, nor perform proper cleanup.
Rewrite the code to process each entry in a helper function, and make
server_process_native_message() just call this function in a loop.
Fixes#5643.
v2:
- properly decrement *remaining when processing entry separator
The intent of the hwdb entry for the Cube iWork8 air tablet buttons is
to fix them being swapped. The kernel is using left-meta for the
home key (it is being treated as the windows key on keyboards, as it has
a windows logo on most x86 tablets).
Fix the hwdb entry to only swap the buttons and not change the keycode
emitted by the home key.
timex::time::tv_sec can have different sizes depending on the
host architecture. On x32 in particular, it is 8 bytes
long while the long int type is only 4 bytes long. Hence,
using li as a format specifier will trigger a format
error. Thus, better use PRI_TIME instead of li which is
actually the right format specifier to use for time_t.
Enable masking the /proc folder using the 'InaccessiblePaths' unit
option.
This also slightly simplify mounts setup as the bind_remount_recursive
function will only open /proc/self/mountinfo once.
This is based on the suggestion at:

timex::time::tv_usec and timex::freq can have different sizes
depending on the host architecture. On x32 in particular,
it is 8 bytes long while the long int type is only 4 bytes
long. Hence, using li as a format specifier will trigger
a format error. Thus, introduce a new format specifier
PRI_TIMEX which is defined as PRIi64 on x32 and li
everywhere else.
timespec::tv_nsec can have different sizes depending on the
host architecture. On x32 in particular, it is 8 bytes long
while the long int type is only 4 bytes long. Hence, using
ld as a format specifier will trigger a format error. Thus,
explicitly cast timespec::tv_nsec to nsec_t and use PRI_NSEC
as the format specifier to make sure the sizes for both match.

When we first handle a device with an EVDEV_ABS override, check if it has
EV_ABS bits. If not, print a warning and continue. This is required on devices
where the match string applies to multiple device nodes, not all of which may
have absolute axes.

c20e6de897 introduced a format string as
variable, but didn't turn off -Wformat-nonliteral warnings on it, thus
breaking the build. Let's fix that, by simply turning off the warning in
this case, as we know it's safe.
test-login.c is largely rewritten to use _cleanup_ and give more meaningful
messages (function names are used instead of creative terms like "active
session", so that when something unexpected is returned, it's much easier to
see what function is responsible).
The monitoring part is only activated if '-m' is passed on the command line.
It runs against the information from /run/systemd/ in the live system, but that
should be OK: logind/sd-login interface is supposed to be stable and both
backwards and forwards compatible.
If not running in a login session, some tests are skipped.
Those two changes together mean that it's possible to run test-login in the
test suite.
Tests for sd_pid_get_{unit,user_unit,slice} are added.
sd_seat_get_sessions returns two arrays, that in principle should always match:
the session names and corresponding uids. The second array could be shorter only
if parsing or uid conversion fails. But in that case there is no way to tell
*which* uid is wrong, so they are *all* useless. It's better to simplify things and
just return an error if parsing fails.
As described by Luke Shumaker:
sd_seat_get_sessions looks at /run/systemd/seats/${seat_name}:SESSIONS to get
the list of sessions (which I believe is correct), and at
/run/systemd/seats/${seat_name}:ACTIVE_SESSIONS for the list of users (which
I believe is incorrect); I believe that it should look at the UIDS field for
the list of users. As far as I can tell, the ACTIVE_SESSIONS field is never
even present in the seats file. I also believe that this has been broken
since the function was first committed almost 6 years ago.
Fixes#5743.
