2020-12-09mount: fix incorrect "success" exitcode if loop device setup failsDenys Vlasenko
When mounting, in parallel, multiple loop devices (squashfs for the submitter's case), the following behavior can be observed: stat64(/path/to/image, {st_mode=S_IFREG|0644, st_size=4096, ...}) = 0 openat(AT_FDCWD, /path/to/image, O_RDWR|O_LARGEFILE) = 3 openat(AT_FDCWD, /dev/loop-control, O_RDWR|O_LARGEFILE|O_CLOEXEC) = 4 ioctl(4, LOOP_CTL_GET_FREE) = 12 close(4) = 0 openat(AT_FDCWD, /dev/loop12, O_RDWR|O_LARGEFILE) = 4 ioctl(4, LOOP_GET_STATUS64, {lo_offset=0, lo_number=12, lo_flags=LO_FLAGS_AUTOCLEAR, lo_file_name=/path/to/image, ...}) = 0 close(4) = 0 close(3) = 0 write(2, "mount: can't setup loop device\n", 31mount: can't setup loop device ) = 31 exit_group(0) = ? +++ exited with 0 +++ The ioctl LOOP_CTL_GET_FREE has resulted in the same result for a competing mount process. The subsequent ioctl LOOP_GET_STATUS64 fails, having succeeded for the competing mount process. Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

2020-11-22mdev: add -v to increase log verbosityJan Klötzke
If logging to stderr and/or syslog the -v option can be given one or more times to increase the log verbosity. If mdev is used as hotplug helper the log level is fixed set to 2 if mdev.log is found an appended because there is no possiblity to pass arguments to the hotplug helper.

2020-11-22mdev: add syslog logging modeJan Klötzke
If mdev is run as daemon it should be possible to forward the debug messages to syslog. This feature might be useful if mdev is run with -s during boot too. OTOH it makes no sense for the daemon to log to mdev.log. This can be handled by a syslog daemon way better. If the daemon stays in the foreground due to -f, the messages are still written to stderr as before.

2020-11-22mdev: re-initialize if uevent messages were lostJan Klötzke
If the netlink read() failed with ENOBUFS we know that we have missed at least one message due to a socket receive buffer overrun. The only way how to recover is to drop the old socket, open a fresh one and make a cold-plug scan of the current system state.
