* build-sys: do not require dirfd()Karel Zak2018-12-031-2/+6
| | | | | | | 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/sysfs: new implementationKarel Zak2018-06-211-2/+5
| | | | | | | | | * reuse ul_path_* API * allow to use prefix for sysfs paths, so we can use snapshots from sysfs for regression tests Signed-off-by: Karel Zak <kzak@redhat.com>
* lib/path: new implementationKarel Zak2018-06-211-1/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

* build-sys: always use global LDADDRuediger Meier2016-02-231-4/+4
| | | | | | | | This was a major showstopper when building on a system where LTLIBINTL libs are needed (e.g. OSX). Maybe there are a few test programs which wouldn't need LDADD ... never mind. Signed-off-by: Ruediger Meier <ruediger.meier@ga-group.nl>

* lib/colors: use libtinfo to check terminal capabilityKarel Zak2015-02-271-2/+12
| | | | | | | | | | | | | | | The current implementation assumes that all terminals supports colors and users are forcet to use terminal-colors.d/ to disable colors for some terminals. This patch checks for maximal supported colors for the current terminal and colors are automatically disabled for terminals like vt100. The patch moves lib/colors.c from libcommon.la to libtcolors.la to avoid collisions with another utils. Signed-off-by: Karel Zak <kzak@redhat.com>

* loopdev: sync capacity after setting itJeff Mahoney2013-04-091-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I recently tried to mount an hfsplus file system from an image file with a partition table by using the loop offset and sizelimit options to specify the location of the file system. hfsplus stores some metadata at a set offset from the end of the partition, so it's sensitive to the device size reported by the kernel. It worked with this: But failed with this: /dev/loop0: [0089]:2 (<imagefile>), offset 32768, sizelimit 102400000 /dev/loop1: [0089]:2 (<imagefile>), offset 32768, sizelimit 102400000 /proc/partitions shows the correct number of blocks to match the sizelimit. But if I set a breakpoint in mount before the mount syscall, I could see: 102400000 102432768 The kernel loop driver will set the gendisk capacity of the device at LOOP_SET_STATUS64 but won't sync it to the block device until one of two conditions are met: All open file descriptors referring to the device are closed (and it will sync when re-opened) or if the LOOP_SET_CAPACITY ioctl is called to sync it. Since mount opens the device and passes it directly to the mount syscall after LOOP_SET_STATUS64 without closing and reopening it, the sizelimit argument is effectively ignroed. The capacity needs to be synced immediately for it to work as expected. This patch adds the LOOP_SET_CAPACITY call to loopctx_setup_device since the device isn't yet released to the user, so it's safe to sync the capacity immediately.

* unshare,nsenter: spawn shell by defaultZbigniew Jędrzejewski-Szmek2013-02-141-1/+2
| | | | | | | | | | | | | The behaviour mimics chroot. Possibly it would have been nicer to to query the password database in the new namepace and run the shell of the user there, but it's hard to do correctly. getpwuid() might need to load nss plugins, and the arch in the new namespace might be different (in case of NEWNS mounts), or the hostname might be different, etc. So in general it's not possible to do it reliably.
