* tests: fix trailing spaces in cal(1) stuffKarel Zak2014-02-173-389/+391

* libmount: initialize *root to NULL in mnt_table_get_root_fsThomas Bächler2014-02-171-0/+2
| | | | | | | | mnt_table_get_root_fs only works when *root is set to NULL. This is not only undocumented, but also unintuitive. Fix it by initializing *root inside mnt_table_get_root_fs. Signed-off-by: Karel Zak <kzak@redhat.com>
* su: don't use kill(0, ...) when propagate signalKarel Zak2014-02-171-1/+1
| | | | | | | | | | | The current code uses kill(0, caught_signal) after regular signal cleanup and before exit (all just to make shells happy). Unfortunately, kill(0, ...) is a bad idea. It seems better to use kill(getpid(), ...) otherwise we kill our parent process too. Addresses: https://bugzilla.redhat.com/show_bug.cgi?id=1063887 Signed-off-by: Karel Zak <kzak@redhat.com>

* ionice: add the way to specify the target processes with pgid and uidMasatake YAMATO2014-02-172-22/+74
| | | | | | | | | | | | | ioprio_get and ioprio_set system call accept not only process ID but also process group ID(pgid) and user ID(uid) to specify the target process(es). However, ionice command accepts only process ID. With this patch a user can specify the target processes with pgid(-P option) and uid(-u option).

* fallocate: Add "--dig-holes" optionRodrigo Campos2014-02-143-25/+95
| | | | | | | | | | This option tries to detect chunk of '\0's and punch a hole, making the file sparse in-place. [kzak@redhat.com: - fix coding style, use xalloc.h and err.h] Signed-off-by: Rodrigo Campos <rodrigo@sdfg.com.ar> Signed-off-by: Karel Zak <kzak@redhat.com>
* fallocate: Hide #ifdef tricks to call fallocate in a functionRodrigo Campos2014-02-141-15/+28
| | | | | | | | | | | | Future patches will add more calls to fallocate(), so it will be useful to have all these tricks inside a function. The error message when fallocate is not supported is slightly changed: the file name is not printed as a prefix because is not available in the context of the function. Also, to only print one of the two possible errors (as happens when using directly exit()), an else clause was added. Signed-off-by: Rodrigo Campos <rodrigo@sdfg.com.ar>
* fallocate: Clarify that space can also be deallocatedRodrigo Campos2014-02-142-7/+8
| | | | | | | The functionality is already there, with --punch-hole, but the text was for the preallocation case only. Signed-off-by: Rodrigo Campos <rodrigo@sdfg.com.ar>

* renice: correct max priority in renice man pagePhillip Susi2014-02-101-7/+3Star
| | | | | | | | | | | | The man page stated that the PRIO_MAX is 20. While this is correct, the header definition is wrong and the max value is actually 19.

* mount: remove obsolete and confusing statement from mount.8Phillip Susi2014-02-101-2/+1Star
| | | | | | | The wording was confusing and suidperl has gone the way of the dodo, and really didn't need mentionting in mount.8. Signed-off-by: Phillip Susi <psusi@ubuntu.com>
* fix mkfs --verbose and man pagePhillip Susi2014-02-102-6/+2Star
| | | | | | | | | mkfs did not actually accept the long form --verbose option. Also the man page seemed to indicate that version/verbose/help options were passed to the filesystem specific utility when this is not the case. Signed-off-by: Phillip Susi <psusi@ubuntu.com>

* setpriv: Fix --apparmor-profileAndy Lutomirski2014-02-101-2/+2
| | | | | | | | | | | | | | | There were two bugs. First, trying to access /proc/self/attr/exec with O_CREAT | O_EXCL has no chance of working. Second, it turns out that the correct command to send is "exec", not "changeprofile". Of course, there was no way to know this until: commit 3eea57c26e49a5add4c053a031cc2a1977b7c48e Author: John Johansen <john.johansen@canonical.com> Date: Wed Feb 27 03:44:40 2013 -0800 apparmor: fix setprocattr arg processing for onexec Signed-off-by: Andy Lutomirski <luto@amacapital.net>
* last: make session gone determination more robustSami Kerola2014-02-101-3/+22
| | | | | | | | | | | | Earlier determination that used kill with signal zero to pid was prone to false positive reports, due reuse of pid space and unrelated processes. New function is_phantom() tries do a little bit better job, but fails to be perfect. It seems linking to gether utmp session start time or terminal id with /proc/<pid>/ information is not as simple as one might hope.

| | | | | | | | | | | | | | | | | | | | This is done to keep things simple, when considering tests, for both 64 and 32 bit architectures. Setting the upper limit of a year value to to 2^31-1 (2147483646) should be enough for anyone.

* | losetup: wait for udevKarel Zak2014-01-242-5/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | On system with /dev/lop-control the udevd creates /dev/loopN nodes. It seems better to wait a moment after unsuccessful open(/dev/loopN) and try it to open again. The problem is pretty visible on systems where udevd also modifies permission for loopN devices, then open() fails with EACCES when losetup executed by non-root user (but user who is in "disk" group).

* | include/c.h: prefer nanosleep() over usleep()Karel Zak2014-01-248-16/+25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Let's use nanosleep() although if usleep() exists. The nanosleep function does no interact with signals and other timers. The patch introduces xusleep() as replacement to libc (or our fallback) usleep(). Yes, we don't want to use struct timespec + nanosleep() everywhere in code as nano-time resolution is useless for us. The patch also enlarges delays in some busy wait loops. It seems enough to try read/write 4x per second. Signed-off-by: Karel Zak <kzak@redhat.com>
