* docs: fix typos [codespell]Sami Kerola2019-02-182-5/+5

* lib/loopdev: set blocksize when create a new deviceKarel Zak2019-01-221-0/+23
| | | | | | | | | | | The partition scanner in kernel depends on blocksize. We need to set the blocksize before we call LOOP_SET_STATUS64 (this ioctl triggers the scanner). This patch extends the internal API to save blocksize into loopdev context to be usable later for loopcxt_setup_device(). Signed-off-by: Karel Zak <kzak@redhat.com>
* lib/loopdev: differentiate between setter()s and ioctl callsKarel Zak2019-01-221-5/+5
| | | | | | | | Now the internal API uses loopcxt_set_...() to set context variables as well as to call ioctls. This patch introduces loopcxt_ioctl_...() to makes things more obvious to readers. Signed-off-by: Karel Zak <kzak@redhat.com>

* timeutils: match today day and this year correctlySami Kerola2019-01-121-12/+15
| | | | | | | | | Assumption all years since 1970 have been exactly 365 days long has it's problems when leap years happen. Lets use struct tm fields that are provided by localtime_r(), making year and day to be correctly compared even when it's late new years eve somewhere else than UTC-0.

| | | | | | | The dirfd() is required on many places, but it should not be required for all utils by ./configure.ac. Signed-off-by: Karel Zak <kzak@redhat.com>
* lib/timer: add fallback if timer_create() not availableKarel Zak2018-12-031-5/+35
| | | | | | | | | | | | | * add struct ul_timer as API abstraction to hide differences between timer_create() and setitimer() * add setitimer() detection to ./configure.ac * add fallback code to use setitimer() if timer_create() not available (for example on OSX) Addresses: https://github.com/karelzak/util-linux/issues/584 Signed-off-by: Karel Zak <kzak@redhat.com>

* lib/canonicalize: do restricted canonicalize in a subprocessRian Hunter2018-11-301-22/+77
| | | | | | | | | | | | | | | | | | | Accessing FUSE mounts require suid/sgid (saved uid) to be equal to the owner of the mount. If mount is running as a setuid process, swapping creds by only setting the euid/egid isn't enough to change the suid/sgid as well. We must do a full setuid()/setgid(), but that removes our ability to re-assume the identity of the original euid. The solution is swap creds in a child process, preserving the creds of the parent. [kzak@redhat.com: - use switch() rather than if() for fork - use all-io.h - close unused pipe[] ends - be more strict about used types] Addresses: https://github.com/karelzak/util-linux/pull/705 Co-Author: Karel Zak <kzak@redhat.com> Signed-off-by: Karel Zak <kzak@redhat.com>

* lib/path: new implementationKarel Zak2018-06-212-140/+918
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The goal is to avoid duplicate code in path.c and sysfs.c and make it possible to define prefix for paths for all sysfs and procfs based utils. Now we have /proc snapshots (for tests) for lscpu only. It would be nice to have the same (for sysfs) for lsblk and another tools. * very simple API to read numbers, strings and symlinks * based on openat() pc = ul_new_path("/sys/block/sda"); ul_path_read_u64(pc, &size, "size"); ul_path_read_u64(pc, &lsz, "queue/logical_block_size"); * printf-like API to generate paths, for example: ul_path_readf_u64(pc, &num, "sda%d/size", partno) * allow to define prefix to redirect hardcoded paths to another location, for example: pc = ul_new_path("/sys/block/sda"); ul_path_set_prefix(pc, "/my/regression/dump"); ul_path_read_u64(pc, &num, "size"); to read /my/regression/dump/sys/block/sda/size * allow to extend the API by "dialects", for example for sysfs: pc = ul_new_path(NULL); sysfs_blkdev_init_path(pc, devno, NULL); and use ul_path_* functions to read from @pc initialized by sysfs_blkdev_init_path() * add test_path binary Signed-off-by: Karel Zak <kzak@redhat.com>
