Hi guys,

I just found out that /usr/bin/logger does not correctly report error when
it's not able to send messages to syslog.

Here are the steps to reproduce:

When everything's running fine, it sends the message to /dev/log and exits
0:

strace -f logger -i -d -p local0.alert 'Syslog test'

(...)

lstat("/run/systemd/system/", {st_mode=S_IFDIR|0755, st_size=120, ...}) = 0
socket(PF_LOCAL, SOCK_DGRAM, 0)         = 3
connect(3, {sa_family=AF_LOCAL, sun_path="/dev/log"}, 110) = 0

(...)

write(3, "<129>Aug 12 20:24:25 cyb[28848]:"..., 44) = 44
close(3)                                = 0
close(1)                                = 0
close(2)                                = 0
exit_group(0)                           = ?
+++ exited with 0 +++


Bug when syslog is not available, it's not able to send log messages but
does not report error message nor exit with non-true return code:

sudo /etc/init.d/rsyslog stop
(...)

strace -f logger -i -d -p local0.alert 'Syslog test'

(...)

connect(3, {sa_family=AF_LOCAL, sun_path="/dev/log"}, 110) = -1 ENOENT (No
such file or directory)

^^^^^^^^^^^^^^^^^^^^^^^^^
close(3)                                = 0
close(1)                                = 0
close(2)                                = 0
exit_group(0)                           = ?
+++ exited with 0 +++
    ^^^^^^^^^^^^^

it stills returns "true" (0) and does not show any error message.

The expected behavior is print an error message and exist with a non-true
return message.

Would it be possible?

Thanks.
