* libmount: clean up header fileKarel Zak2013-03-151-185/+132Star
| | | | | | | | | | | * don't teach people C by header files, so use warn_unused_result attribute only on places where we return allocated memory (to avoid leaks in applications). * merge multiple function attributes to the one list to make it usable with gtk-doc Signed-off-by: Karel Zak <kzak@redhat.com>

* libmount: allow to use propagation flags in fstabKarel Zak2013-01-151-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Linux kernel does not allow to change more than one propagation flag by one mount(2) syscall. The flags also cannot be mixed with another mount options. It means that the propagation flags cannot be stored in /etc/fstab, manual "mount --make-* <mountpoint>" is always necessary after successful mount. Painful... This patch implements additional mount(2) after previous successful mount(2) (or exec /sbin/mount.<type>). For example: mount /dev/sda1 /A -o private,unbindable,ro or fstab entry: /dev/sda1 /A auto ro,private,unbindable is implemented by three mount(2) calls: - 1st mounts /dev/sda1 with MS_RDONLY - 2nd sets MS_PRIVATE flag - 3rd sets MS_UNBINDABLE flag. It's the same as as to manually call: mount /dev/sda1 /A -o ro mount --make-private /A mount --make-unbindable /A This solution is not atomic, and umount(2) is not called if propagation flags are not successfully applied, only error is returned. This change does not affect libmount API, so one beautiful day when mount(2) syscall will be improved we can drop this nasty patch. Signed-off-by: Karel Zak <kzak@redhat.com>

* libmount: clean nonnull attribute usageKarel Zak2012-12-041-211/+104Star
| | | | | | | | | | - 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: allow to disable swap between source and targetKarel Zak2012-07-171-0/+2
| | | | | | | | | | | | | | | | | | | | | In some cases (for example if only one mount argument is given) may be mount request ambivalent: # mount /foo and fstab: /dev/sda5 /foo rw 0 0 /foo /bar bind 0 0 The libmount allows to swap between source and target (if source is not LABEL or UUID) by default. The new function mnt_context_disable_swapmatch() allows to disable this feature. Signed-off-by: Karel Zak <kzak@redhat.com>

* libmount: remove teaser proto for mnt_table_get_nameDave Reisner2012-02-221-1/+0Star
| | | | | | | | | | This function was never implemented, but the proto has existed since the inception of the library. As the libmnt_table struct doesn't include a member necessary to carry the name of the table, simply discard this prototype. If ever a need to break ABI comes up, perhaps this could be revisited.
