* cal: limit year to 32 bit valueSami Kerola2014-02-061-21/+23
| | | | | | | | | | 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.

* fsck: don't return error if fsck.<type> does not existKarel Zak2014-02-061-32/+42
| | | | | | | | | The error message is expected for "really wanted" set of filesystems (extN, ..), otherwise it does not make sense for filesystems like btrfs or xfs. Reported-by: Tom Gundersen <teg@jklm.no> Signed-off-by: Karel Zak <kzak@redhat.com>

* 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>

* wipefs: call BLKRRPART when erase partition tableKarel Zak2014-01-202-8/+36
| | | | | | | | It's better to be smart than make things inconsistent (without BLKRRPART kernel still uses the erased PT and udev-db still contains obsolete information). Signed-off-by: Karel Zak <kzak@redhat.com>
* libblkid: detect alone PMBRKarel Zak2014-01-203-2/+44
| | | | | | | | wipefs(8) has to also erase PMBR, not GPR header only, otherwise the device could be still interpreted as a device with a partition table. Addresses: https://bugzilla.redhat.com/show_bug.cgi?id=1054186 Signed-off-by: Karel Zak <kzak@redhat.com>

Usage example: $ unshare --uts unshare: unshare failed: Operation not permitted $ unshare --user --uts [nfsnobody@odvarok ~]$ hostname swag hostname: you must be root to change the host name $ unshare -r --uts [root@odvarok util-linux]# hostname swag [root@odvarok util-linux]# [kzak@redhat.com: - move code to map_id() - use all-io.h - add paths to pathnames.h] Signed-off-by: Lubomir Rintel <lkundrak@v3.sk> Signed-off-by: Karel Zak <kzak@redhat.com>

* cal: mention where Gregorian reformation happen in September 1752Sami Kerola2014-01-061-6/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | In September 1752 the Gregorian reformation happen in Great Britain and Dominions (including what is now the USA). One could argue the cal(1) should consider locale when determining the reformation, but such is nearly impossible implement correctly. The dates when reformation happen are split by areas that cannot be expressed with current locales, for example the Netherlands is split to two and Germany three categories depending on where in the modern country one is. Secondly the track when reformation happen is lost for some countries, Lithuania or Japan are good examples of such. One of the worst for a programmer is Sweden. They got gradual calendar change which made Swedish calendar to be completely out of sync. Later the Swedish calendar jumped in 1753 to be in sync with everyone else. Notice that some countries, including Saudi Arabia, Ethiopia, Nepal, Iran and Afghanistan, still have not adopted the Gregorian calendar. Hence the output of the cal(1) cannot be considered to be correct for everyone.
