| | | | | | | The commit 96cbe362c034305e5f12a912b4247b3321420ee7 forces lsmem to follow output column for split policy. Signed-off-by: Karel Zak <kzak@redhat.com>

* lsmem: make --split optional, follow output by defaultKarel Zak2017-11-032-27/+36
| | | | | | | | Let's keep lsmem backwardly compatible (<=v2.30) and create ranges according to the output columns by default. This default behavior may be modified by --split command line option. Signed-off-by: Karel Zak <kzak@redhat.com>

| | | | | | | | Without this, 'sfdisk -d' with certain filenames would lead to reading an 's' from the 'type' field in fdisk_reset_labelitem and cause a crash due to prematurely freeing the 'data.str' field. Signed-off-by: Roddy Shuler <roddy@endlessm.com>

* fsck.cramfs: Fix bus error on broken file system.Tobias Stoeckmann2017-11-021-6/+7
| | | | | | | | | | | | | | | | | The utility fsck.cramfs is prone to a bus error on file systems for big endian systems with non-standard header sizes. While calculating the crc32 checksum, it does not properly handle a possible offset for bootcodes, resulting in out of boundary access of mmap'ed area. You can trigger the issue with the following commands: $ mkdir -p cramfs-poc/root/subdir $ cd cramfs-poc $ mkfs.cramfs -p -N big root cramfs $ echo -ne \\00\\x4c | dd of=cramfs bs=1 seek=518 count=2 conv=notrunc $ fsck.cramfs cramfs Signed-off-by: Tobias Stoeckmann <tobias@stoeckmann.org>

* Merge branch 'bash-completion-fsck-find' of ↵Karel Zak2017-11-021-1/+2
|\ | | | | | | | | | | | | https://github.com/kevinoid/util-linux * 'bash-completion-fsck-find' of https://github.com/kevinoid/util-linux: bash-completion: Exclude /dev/fd from fsck find
| * bash-completion: Exclude /dev/fd from fsck findKevin Locke2017-10-301-1/+2
| | | | | | | | | | | | | | | | | | | | | | When the bash-completion for fsck runs `find -L /dev/ -type b` it descends into /dev/fd after opening '.' as file descriptor 3. This causes find to search through /dev/fd/3/ which includes everything below the current directory, which can take a very long time. To avoid this, prune /dev/fd in the find expression.

* | libfdisk: (sun) fix creation of whole disk partitionMikhail Vorobyov2017-11-021-4/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | sun_add_partition() allowed the 1st sector to be 0 for the 3rd partition only if that sector was free or if other partitions covered the whole disk. Now it's always allowed for the 1st sector to be set to 0 for the 3rd partition.

* | dmesg: Add --force-prefix optionPrarit Bhargava2017-11-012-60/+150

These message are currently displayed by dmesg as [965199.028940] runnable tasks: task PID tree-key switches prio wait-time sum-exec sum-sleep ---------------------------------------------------------------------------------------------------------- The kernel timestamps each of these lines with [965199.028940] and the dmesg utility should do the same. Add the 'force-prefix'/'-p' dmesg option to add decode & timestamp information to each line of a multi-line message. Notes: The new print_record() algorithm stores the decode & timestamp information in buffers. If the force-prefix option is used, the message is split into separate lines and each line is prefixed with the stored decode & timestamp information. The splitting of the message into separate lines is done using strtok() which requires write access to the message buffer (ie, the const message buffer is now copied into a writeable buffer). Successfully tested by me by looking at sysrq-t and sysrq-w output. All known good /tests passed with these changes. [kzak@redhat.com: - use snprintf() - cleanup \n usage (don't count line break to the message text in the parsers and always print \n after the text - add the option to the man page - use --force-prefix for kmsg only, old syslog(2) API splits messages itself - strdup() the message text only on force-prefix] Signed-off-by: Prarit Bhargava <prarit@redhat.com> Signed-off-by: Karel Zak <kzak@redhat.com>

* blkid: Add support for LUKS2 and new LABEL attributes.Milan Broz2017-10-231-4/+38
| | | | | | | | | | | | | | | | | | | | | | | | | This patch adds support for detection of a LUKS2 superblock. LUKS2 is new version of Linux Unified Key Setup for encrypted block devices. LUKS2 contains a binary header and then JSON area for metadata. Blkid should only parse the binary part, including newly available optional LABEL and SUBSYSTEM fields. LABEL is similar to filesystem label. The SUBSYSTEM field is in principle, just a second label and can be used for specific udev rules (for example if you have some 3rd party system that activates volumes automatically, you can mark devices using this attribute). Both labels are optional. The magic string and UUID location are intentionally on the same offset as LUKS v1, so even unpatched blkid now recognizes LUKS2. Anyway, the code should not parse other versions of the header, so we now explicitly check for header version and support only version 1 and 2. Signed-off-by: Milan Broz <gmazyland@gmail.com>

| | | | | | | | | | | | | | | | | | | | | | This allows to conveniently kill the entire process tree below the forked program, a common problem when scripting tasks that need to reliably fully terminate without leaving reparented subprocesses behind. The example added to the man page shows the most common use. Implemented using prctl(PR_SET_PDEATHSIG, ...).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Now the way how lsmem lists memory ranges is affected by used output columns. It makes it very difficult to use in scripts where you want to use for example only one column ranges=$(lsmem -oRANGE) and in this case all is merged to the one (or two) huge ranges and all attributes are ignored. The --split allows to control this behavior ranges=$(lsmem -oRANGE --split=STATE,ZONES) forces lsmem to list ranges by STATE and ZONES differences. Signed-off-by: Karel Zak <kzak@redhat.com>

* | lsmem/chmem: add memory zone awarenessGerald Schaefer2017-10-204-11/+246
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With this patch, valid memory zones can be shown with lsmem, and chmem can set memory online/offline in a specific memory zone, if allowed by the kernel. The valid memory zones are read from the "valid_zones" sysfs attribute, and setting memory online to a specific zone is done by echoing "online_kernel" or "online_movable" to the "state" sysfs attribute, in addition to the previous "online". This patch also changes the default behavior of chmem, when setting memory online without specifying a memory zone. If valid, memory will be set online to the zone Movable. This zone is preferable for memory hotplug, as it makes memory offline much more likely to succeed. Signed-off-by: Gerald Schaefer <gerald.schaefer@de.ibm.com>
* | libmount: use eacess() rather than open() to check mtab/utabKarel Zak2017-10-202-6/+14
| | | | | | | | | | | | | | | | | | The open() syscall is probably the most strong way how to check write accessibility in all situations, but it's overkill and on some paranoid systems with enabled audit/selinux. It fills logs with "Permission denied" entries. Let's use eaccess() if available. Signed-off-by: Karel Zak <kzak@redhat.com>
