SUMMARY: AddressSanitizer: SEGV (/lib64/libc.so.6+0xaa285) in __strlen_sse2
==3297==ABORTING

It's an external library and errors in external libraries are generally not very
useful for looking for internal bugs.

It would be better not to change the code and use standard suppression
techinques decribed at
https://clang.llvm.org/docs/AddressSanitizer.html#suppressing-reports-in-external-libraries,
but, unfortunaley, none of them seems to be able to suppress fatal errors in asan intself.

but I think it's a false positive because of our low-level magic in how this

It's a false positive which is most likely caused by
google/sanitizers#852. I think it could be got around
by avoiding `getrandom` when the code is compiled with `msan`

This function returns 0 on success and a negative value on failure. On success,
it writes the parsed action to the address passed in its third argument.

`bus_set_transient_emergency_action` does this:

 r = parse_emergency_action(s, system, &v);
 if (v < 0)
     // handle failure

However, `v` is not updated if the function fails, and this should be checking
`r` instead of `v`.

The result of this is that if an invalid failure (or success) action is
specified, systemd ends up creating the unit anyway and then misbehaves if it
tries to run the failure action because the action value comes from
uninitialized stack data. In my case, this resulted in a failed assertion:

Fix this by checking the correct variable.

This function returns 0 on success and a negative value on failure. On success,
it writes the parsed action to the address passed in its third argument.

`bus_set_transient_emergency_action` does this:

 r = parse_emergency_action(s, system, &v);
 if (v < 0)
     // handle failure

However, `v` is not updated if the function fails, and this should be checking
`r` instead of `v`.

The result of this is that if an invalid failure (or success) action is
specified, systemd ends up creating the unit anyway and then misbehaves if it
tries to run the failure action because the action value comes from
uninitialized stack data. In my case, this resulted in a failed assertion:

I had a test machine with ulimit -n set to 1073741816 through pam
("session required pam_limits.so set_all", which copies the limits from PID 1,
left over from testing of #10921).

test-execute would "hang" and then fail with a timeout when running
exec-inaccessiblepaths-proc.service. It turns out that the problem was in
close_all_fds(), which would go to the fallback path of doing close()
1073741813 times. Let's just fail if we hit this case. This only matters
for cases where both /proc is inaccessible, and the *soft* limit has been
raised.

The source in question is an inotify source, and the messages are:

systemd-homed[1340]: Assertion '*_head == _item' failed at src/libsystemd/sd-event/sd-event.c:3035, function event_inotify_data_drop(). Aborting.

on_home_inotify() got called, then manager_watch_home(), which unrefs the
existing inotify_event_source. I assume that the source gets dispatched again
because it was still in the pending queue.

I can't reproduce the issue (timing?), but this should
fix #17824, https://bugzilla.redhat.com/show_bug.cgi?id=1899264.

When trying to calculate the next firing of 'Sun *-*-* 01:00:00', we'd fall
into an infinite loop, because mktime() moves us "backwards":

Before this patch:
tm_within_bounds: good=0 2021-03-29 01:00:00 → 2021-03-29 00:00:00
tm_within_bounds: good=0 2021-03-29 01:00:00 → 2021-03-29 00:00:00
tm_within_bounds: good=0 2021-03-29 01:00:00 → 2021-03-29 00:00:00
...

We rely on mktime() normalizing the time. The man page does not say that it'll
move the time forward, but our algorithm relies on this. So let's catch this
case explicitly.

Turns out that part of systemd isn't covered by any fuzz targets and
that's not ideal considering that it parses data sent remotely. The
fuzzer triggers an infinite loop in lease_parse_routes as soon as it
starts so it seems to be working :-)

The asertion in question:

Assertion 'm' failed at src/libsystemd/sd-bus/bus-message.c:1015, function sd_bus_message_is_signal(). Aborting.

We can get a NULL message here through sd_bus_process() ->
bus_process_internal() -> process_running(), so let's handle this case
appropriately.

Since in that case the event loop is already finished and we'd hit an

The asertion in question:

We can get a NULL message here through sd_bus_process() ->
bus_process_internal() -> process_running(), so let's handle this case
appropriately.

We can get a NULL message here through sd_bus_process() ->
bus_process_internal() -> process_running(), so let's handle this case
appropriately.
