* lib/randutils: remove unnecessary functionKarel Zak2016-10-041-1/+0Star
| | | | Signed-off-by: Karel Zak <kzak@redhat.com>
* lib/strutils: make left and right trims more robustSami Kerola2016-09-291-2/+7
| | | | | | | Do not follow null pointer, and stop going any further when ltrim_whitespace() is at the end of a string. Signed-off-by: Sami Kerola <kerolasa@iki.fi>
* debug: use const void * for ul_debugobj()Igor Gnatenko2016-09-211-1/+1
| | | | | | | | | | We don't modify data it's pointing out and we should not modify it. Also remove casting to void * as gcc will do it automatically (before we had to cast it explicitly to avoid warning on discarding 'const' qualifier). Signed-off-by: Igor Gnatenko <i.gnatenko.brain@gmail.com>
* libsmartcols: support multi-line cells based on line breaksKarel Zak2016-09-061-1/+1
| | | | | | | | | | Now libsmartcols completely control when and how wrap long lines/cells. This is sometimes user unfriendly and it would be nice to support multi-line cells where wrap is based on \n (new line char). This patch add new column flag SCOLS_FL_WRAPNL.

* loopdev: Implememt loopcxt_set_status()Stanislav Brabec2016-08-171-0/+1
| | | | | | | | | | | | Implement stand-alone loopcxt_set_status(). It allows manipulation with some loop device parameters even if it is initialized. Its function is limited by the kernel implementation, and only a small subset of changes is allowed. For more see linux/drivers/block/loop.c:loop_set_status() Signed-off-by: Stanislav Brabec <sbrabec@suse.cz>

* libmount: ignore redundant slashesKarel Zak2016-08-081-1/+1
| | | | | | | | | | | | | | | ///aaa/bbb and /aaa/bbb/ are the same paths. This is important especially with NFS where number of slashes are not the same in the /proc/self/mountinfo and fstab or utab. The regular URI is euler://tmp but /proc contains euler:/tmp Reported-by: Ales Novak <alnovak@suse.cz> Signed-off-by: Karel Zak <kzak@redhat.com>

* Implement loopcxt_check_conflict()Stanislav Brabec2016-08-031-0/+3
| | | | | | | Add a function that searches for a possible conflicting (i. e. overlaying loop device). Signed-off-by: Stanislav Brabec <sbrabec@suse.cz>
* Add sizelimit to internal APIStanislav Brabec2016-08-031-3/+5
| | | | | | | | | | | | | | Fully safe checks of loop device need to check sizelimit. To prevent need of two nearly equal functions, introduce sizelimit parameter to several internal functions: loopdev_is_used() loopdev_find_by_backing_file() loopcxt_is_used() loopcxt_find_by_backing_file() If sizelimit is zero, fall back to the old behavior (ignoring of sizelimit).

* lib: try to find tty in get_terminal_name()Sami Kerola2016-07-041-1/+1
| | | | | | | | Try all standard terminal input/output file descriptors when finding tty name in get_germinal_name(). This should make all invocations of the function as robust as they can get. Signed-off-by: Sami Kerola <kerolasa@iki.fi>
* libcommon: add ISO_8601_GMTIME that will print UTC-0 timestampsSami Kerola2016-06-261-1/+2
| | | | | | | When timestamps are intented to be conversable back from string to binary it is best to stick with UTC-0 timezone. This is needed in utmpdump(1). Signed-off-by: Sami Kerola <kerolasa@iki.fi>

* libmount: try absolute target before canonicalizeKarel Zak2016-04-131-0/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The path canonicalization is expensive and in many cases unwanted due to problems with readlink() on unreachable NFS and automounters. This patch add a possibility to search also by $(CWD)/<path> if the <path> is relative to reduce number of situation when we convert the path to the canonical absolute path. The common use-case: # cd /some/long/path # umount ./mountpoint old version: 15543: libmount: TAB: [0x560a99a54230]: lookup TARGET: './test' 15543: libmount: CACHE: [0x560a99a54290]: canonicalize path ./test 15543: libmount: CACHE: [0x560a99a54290]: add entry [ 1] (path): /mnt/test: ./test 15543: libmount: TAB: [0x560a99a54230]: lookup canonical TARGET: '/mnt/test' 15543: libmount: CXT: [0x560a99a54050]: umount fs: /mnt/test new version: 15597: libmount: TAB: [0xabf230]: lookup TARGET: './test' 15597: libmount: TAB: [0xabf230]: lookup absolute TARGET: '/mnt/test' 15597: libmount: CXT: [0xabf050]: umount fs: /mnt/test Signed-off-by: Karel Zak <kzak@redhat.com>
