* lib/timer: add fallback if timer_create() not availableKarel Zak2018-12-031-3/+5
| | | | | | | | | | | | | * add struct ul_timer as API abstraction to hide differences between timer_create() and setitimer() * add setitimer() detection to ./configure.ac * add fallback code to use setitimer() if timer_create() not available (for example on OSX) Addresses: https://github.com/karelzak/util-linux/issues/584 Signed-off-by: Karel Zak <kzak@redhat.com>

| * | fix a bug where switch_root would erroneously try to parse initargsPaul Asmuth2018-11-121-1/+1
| | | | | | | | | | | | | | | | | | before this change, switch_root would try to parse all arguments, including 'initargs', using getopt, which would lead to an 'unrecognized option' error when trying to pass a flag to the init program
* | | fstrim: Add hardening settings to fstrim.serviceAndreas Henriksson2018-11-221-0/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This limits what the fstrim process has access to when it runs. PrivateUsers can't be enabled because of: "If this mode is enabled, all unit processes are run without privileges in the host user namespace[...]" Further improving this with additional option or making things even tighter is most likely possible.

* | unshare: allow to set user ID and group IDLaurent Vivier2018-11-122-3/+34
| | | | | | | | | | | | | | | | | | | | | | This patch introduces two new parameters to set the user ID and the group ID of the program to be executed. Setting group ID also drops supplementary groups. The option names used are the same as for nsenter, -S, --setuid and -G, --setgid. Signed-off-by: Laurent Vivier <laurent@vivier.eu>
* | unshare: allow to set a new rootLaurent Vivier2018-11-122-5/+35
|/ | | | | | | | | | | | | | | This patch instroduces two new parameters to set the new root and the new working directory in this new root. This allows to combine "unshare chroot" in one command, and doing like this the /proc filesystem is correctly mounted in the new root with "--mount-proc". The new parameters are -R, --root and -w, --wd. The names are the same as for nsenter, except for "-r" that is already used by "--map-root-user" and replaced by "-R".

* fstrim: update .service to follow /etc/fstabKarel Zak2018-08-081-2/+2
| | | | | | | | | | | Replace -a with -A to discard mounted filesystems from /etc/fstab. The original -a forces fstrim to try to discard all filesystems, including for example manually mounted removable media. It seems better for widely used .service unit to follow /etc/fstab.

* hwclock: rely on kernel for RTC_UIE_ON on Aplha and SparcKarel Zak2018-08-031-11/+2Star
| | | | | | | | | | | It's kernel business to return EINVAL for unsupported RTC_UIE_ON. We (userspace) should not make decisions about things that we do not control. If kernel is wrong then fix the kernel, don't hide the problem by crazy ifdefs in userspace. Signed-off-by: Karel Zak <kzak@redhat.com>
* umount: add --quiet optionKarel Zak2018-08-012-3/+24
| | | | | | | | | | | | | | | The command umount supports things like --all-targets and --recursive to umount all nodes in specified tree. Sometimes it makes sense to aggressively use wildcards like /dev/sdb* and in this case --quiet seems like a good choice umount --quiet --all-targets /dev/sdb* to suppress 'not mounted' error messages. The new option suppress only these error messages and nothing else. Addresses: https://github.com/karelzak/util-linux/issues/672 Signed-off-by: Karel Zak <kzak@redhat.com>

| | | | | | | | | | | | | | | | | | | | | | Some mistakes happened lately when switching from path_exist() to ul_path_access(). See f09a98de and 8ca31279. This caused ipcs test failures when running i386 binaries on x86_64 hosts, because the syscall fallback was always used. That's why I reviewed all similar changes and found another one in chmem.
