* libmount: optimize tab files parsingKarel Zak2013-02-261-20/+20
| | | | | | | - ignore empty files - ignore empty tables Signed-off-by: Karel Zak <kzak@redhat.com>
* libmount: read optional mountinfo fieldsOndrej Oprala2013-01-101-0/+2
| | | | | | | | | | [kzak@redhat.com: - rename struct member and functions from "propagation" to "optional fields" - split the original patch - fix parser] Signed-off-by: Ondrej Oprala <ondrej.oprala@gmail.com> Signed-off-by: Karel Zak <kzak@redhat.com>
* libmount: clean nonnull attribute usageKarel Zak2012-12-041-2/+4
| | | | | | | | | | - use __attribute__((nonnull) for functions where we not able to return an return code ("is", "has" and some "get" functions). - use __attribute__((nonnull) for small functions where we always modify any of the function argument (some mnt_optstr_* functions) Signed-off-by: Karel Zak <kzak@redhat.com>

* libmount: add mnt_fs_streq_srcpath()Karel Zak2012-03-021-1/+1
| | | | | | | | | | We have to be careful with "none" or another dummy sources for pseudo filesystems. These strings should be canonicalized or compared as a paths. The function is not exported by library API. Signed-off-by: Karel Zak <kzak@redhat.com>
* libmount: don't treat "none" differentlyDave Reisner2012-03-021-6/+1Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This causes more problems than it solves. In the latest edition: # mount -t proc none foo mount: foo: mount failed: Invalid argument A check for source and target fails in mnt_context_apply_fstab() because, even though they were indeed specified on the cmdline, __mnt_fs_set_source_ptr() altered this and NULL'd out the source. If you're able to mount this device via other means, other tools start reporting oddities, such as mount's output: (null) on /foo type proc (rw,relatime) or findmnt: TARGET SOURCE FSTYPE OPTIONS /foo proc rw,relatime Simply treat "none" like any other source when passed in. [kzak@redhat.com: - don't translate NULL to "none" in mnt_fs_set_source()] Signed-off-by: Dave Reisner <dreisner@archlinux.org> Signed-off-by: Karel Zak <kzak@redhat.com>

* libmount: remove fstab.d supportKarel Zak2012-01-241-4/+0Star
| | | | | | | | If you really need to store your configuration to a alternative files then you have to explicitly specify the files or directories on mount(8) command line by --fstab option. Signed-off-by: Karel Zak <kzak@redhat.com>
* libmount: support dirs for mnt_table_parse_fstab(), add mnt_table_parse_dir()Karel Zak2012-01-231-26/+37

* libmount: fix a potential memory leak at mnt_table_parse_dirMasatake YAMATO2012-01-231-4/+7
| | | | | | | | mnt_table_parse_dir in libmount/src/tab_parse.c calls scandir, and then opendir. When the latter one, opendir is failed, buffers allocated in scandir are not released. Signed-off-by: Masatake YAMATO <yamato@redhat.com>
* libmount: Use filter arg of scandir* to pickup /etc/fstab.d/*.fstab filesMasatake YAMATO2012-01-231-36/+27Star
| | | | | | | | | | | | | | | | | | | This patch is based on my last patch: [PATCH 1/2] scandirat based mnt_table_parse_dir implementation scandir* used in `mnt_table_parse_dir in libmount/src/tab_parse.c can take filter function as an argument. `mnt_table_parse_dir' picks up fstab files from namelist returned from scandir* for itself. However, some parts of picking-up job can be done in the filter function. This patch introduces a new function `mnt_table_parse_dir_filter' to share the code for picking-up job between two implementations of `mnt_table_parse_dir_filter', scandir based and scandirat based.

* libmount: scandirat based mnt_table_parse_dir implementationMasatake YAMATO2012-01-231-2/+63
| | | | | | | | | | | | In comment of `mnt_table_parse_dir' of libmount/src/tab_parse.c: /* TODO: it would be nice to have a scandir() implementation that * is able to use already opened directory */ Nowadays glibc provides `scandirat'. This patch implements `scandirat' based `mnt_table_parse_dir'. Signed-off-by: Masatake YAMATO <yamato@redhat.com>

* build-sys: check scanf %ms modifierKarel Zak2011-10-101-11/+12
| | | | | | | | | | | | Without the check libmount builds on systems that has older than 2.7 glibc are silently unsuccessful. The missing %ms modifier will, at least, result on such system missing output of findmnt and lsblk commands. If either %ms or %as modifiers are present the libmount build is disabled.
