* include/c: Define F_DUPFD_CLOEXEC on kFreeBSD systems if missingGuillem Jover2015-06-081-0/+6
| | | | | | | The kernel of FreeBSD version 10 and higher supports this fcntl command, but the system libc, in this case glibc, might not yet know about it. Signed-off-by: Guillem Jover <guillem@hadrons.org>

* lib/sysfs: rename devname functions, cleanupKarel Zak2015-05-281-8/+5Star
| | | | | | | | | | | | | | | | | | Well, I don't have mental power to use function names like sysfs_devname_to_dev_name() so this patch renames to sysfs_devname_sys_to_dev() sysfs_devname_dev_to_sys() It also cleanups usage of the functions. We have to be sure that sysfs.c code returns regular devnames. The existence of the sysfs devnames (with '!') should be completely hidden in sysfs specific code.

* lib/sysfs: Fix /dev to /sys node name translationStanislav Brabec2015-05-281-1/+19
| | | | | | | | | | | | | | | d0dc6c1 introduced translation of /sys names to /dev names, as required by the kernel linux/drivers/base/core.c: device_get_devnode(). But there are other places of code that use /dev names in /sys. They need reverse translation from '/' to '!'. For example, fdisk -l returns empty list since a22c6eb for device nodes in subdirectories (used e. g. by cciss driver). Introduce yet another helper sysfs_dev_name_to_devname() and use it where appropriate. Signed-off-by: Stanislav Brabec <sbrabec@suse.cz>
* Fix /sys to /dev node name translationStanislav Brabec2015-05-261-0/+18
| | | | | | | | | | | | | | linux/drivers/base/core.c: device_get_devnode() defines a translation of '!' in sysfs nodes to '/' in /dev nodes. The same translation has to be done to properly support device nodes with slash (e. g. device nodes of cciss driver and several other drivers). Introduce new helper sysfs_devname_to_devno() and use it where appropriate. Fixes for example lsblk -f on devices using cciss driver. Signed-off-by: Stanislav Brabec <sbrabec@suse.cz>

* lib/strutils: fix string_add_to_idarray() int vs. size_tKarel Zak2015-04-221-1/+1
| | | | | | | | | | | | | | | | | | | | The function uses "int" as argument, but for array size (and index) is better to use unsigned type (size_t). If we mix "size_t" in util (e.g. fdisk) and "int" in lib/strutils.c then result is unexpected behavior on ppc64. # sfdisk --list -o DEVICE,START,SIZE /dev/sdb Disk /dev/sdb: 50 MiB, 52428800 bytes, 102400 sectors Units: sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 4096 bytes I/O size (minimum/optimal): 4096 bytes / 32768 bytes Disklabel type: gpt Disk identifier: 3B8559DB-33AF-43E9-BEFC-C331D829B539 lt-sfdisk: libfdisk/src/label.c:178: fdisk_label_get_field: Assertion `id > 0' failed.

* lib/timer: use separate file for timersKarel Zak2015-03-063-21/+25
| | | | | | | | It seems that static builds require -lpthread for timer_* functions. It's better to keep it out of our libs (e.g. libmount) to avoid unnecessary dependence. Signed-off-by: Karel Zak <kzak@redhat.com>

| | | | | | | | | | | | http://www.freedesktop.org/software/systemd/man/os-release.html The file /etc/os-release takes precedence over /usr/lib/os-release.

| | | | | | | | | | | | | | | | | | | | | | | | | | The directories /{sbin,bin} are symliks to /usr/{sbin,bin} on many systems. This patch add new ./configure option to remove the non-usr paths from the default $PATH environment variable.

| | | | | | | | | | | | | | | In rare cases droping groups with setgroups(0, NULL) is an operation that can grant a user additional privileges. User namespaces were allwoing that operation to unprivileged users and that had to be fixed. Update unshare --map-root-user to disable the setgroups operation before setting the gid_map. This is needed as after the security fix gid_map is restricted to privileged users unless setgroups has been disabled. Signed-off-by: "Eric W. Biederman" <ebiederm@xmission.com>

* libmount: add new libmnt_monitor APIKarel Zak2014-12-051-0/+6
| | | | | | | | | | | | It's usually enough to us [e]poll() to monitor kernel mount table, but there is no way how to monitor changes in userspace mount options (e.g. _netdev).
