* lscpu: avoid double freeSami Kerola2014-07-131-1/+1
| | | | | | The double free was possible for architectures other than x86_64 or i386. Signed-off-by: Sami Kerola <kerolasa@iki.fi>
* setpriv: avoid alloca() use xmalloc() insteadSami Kerola2014-07-131-1/+3
| | | | | | | | | | | | The getgroups() can return up to NGROUPS_MAX supplementary groups, that is (since kernel 2.6.3) 65536 in total. The git_t is 4 bytes, so maximum request is 256 kilobytes. When a system happen to have memory preasure alloca() may not be able to allocate enough memory, making debugging unnecessarily difficult. IMHO 64 pages is significant enough amount of memory to be properly error checked at a time of allocation.

* hwclock: sometimes one day lasts 23 hours.peppe2014-06-231-1/+1
| | | | | | | | | | | If less than 23 hours have passed since the last calibration, hwclock says "Not adjusting drift factor because it has been less than a day since the last calibration.", but in fact compares to 23 hours, not 24.

* flock: document exit status of flock in man pagePhillip Susi2014-06-091-0/+3
| | | | | The man page did not indicate that the exit status of flock is actually that of the child command, when one is run.
* umount: Make sure exit code does not overflowNicolas Boichat2014-06-071-1/+1
| | | | | | | | | | | | | | | | POSIX exit code is only 8-bit, and since umount sums up error codes, it can sometimes report success (exit code 0) even though a number of operations failed. For example, running, in an empty directory: umount `seq 1 7` returns 224 (7*32), since none of the 7 mount point exists but umount `seq 1 8` returns 0 (8*32=256) This patch clips the return value to 255.

| | | | | | | | | | | | | | | | | | | | losetup ignores the EBUSY error. In the loop fo A_CREATE action, it skips the error handling when errno = EBUSY. It's OK for the case where no loop device is specified, but the error has to be handled when the device is given explicitly.

* hwclock: Prevent excessive drift valuesStanislav Brabec2014-05-061-10/+28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Failure of CMOS battery can cause writing of excessive drift values (up to many years per day). This causes excessive hwclock adjustment next time, which may lead to overflow in calculate_adjustment() (and hang before 4a44a54b). Prevent this situation, check drift for limits and reset drift to zero instead. Steps to reproduce: mv /etc/adjtime /etc/adjtime.backup rm /etc/adjtime hwclock --set --date 2001-01-01\ 01:00:00 changing of /etc/adjtime. mv /etc/adjtime /etc/adjtime.saved hwclock --set --date 2001-01-02\ 01:00:01 mv /etc/adjtime.saved /etc/adjtime echo "======= The /etc/adjtime has a \"correct\" look:" cat /etc/adjtime hwclock --debug --systohc --utc echo "======= The /etc/adjtime now has deeply failed drift value:" cat /etc/adjtime mv /etc/adjtime /etc/adjtime.saved hwclock --set --date 2015-01-01\ 01:00:00 mv /etc/adjtime.saved /etc/adjtime hwclock --debug --adjust echo "======= And the last /etc/adjtime:" cat /etc/adjtime mv /etc/adjtime.backup /etc/adjtime hwclock --systohc --utc Signed-off-by: Stanislav Brabec <sbrabec@suse.cz>
