* include/xalloc: ensure xstrdup() and xstrndup() returns nonnull attributeSami Kerola2019-07-141-1/+7
| | | | | | | Turned out lsblk is passing null as argument to xstrdup(), so fix that and add assert() to make sure promise of not returning null is kept in future. Signed-off-by: Sami Kerola <kerolasa@iki.fi>
* lsblk: force to print PKNAME for partitionKarel Zak2019-06-271-0/+3
| | | | | | | | | | PKNAME (parent kernel device name) is based on printed tree according to parent -> child relationship. The tree is optional and not printed if partition specified (.e.g "lsblk -o+PKNAME /dev/sda1"), but old versions print the PKNAME also in this case.

* lsblk: add --dedup <column>Karel Zak2018-12-071-2/+64
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The target use-case are systems with large number of multi-path devices or systems with duplicate (copied) filesystems. The feature is flexible enough to use arbitrary column (for example WWM or UUID, ...) as de-duplication key. For example tree with multi-path devices sd{c,d,e,f} ./lsblk NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT sda 8:0 0 223.6G 0 disk ├─sda1 8:1 0 200M 0 part /boot/efi ├─sda2 8:2 0 200M 0 part /boot ├─sda3 8:3 0 130.3G 0 part ├─sda4 8:4 0 50G 0 part / └─sda5 8:5 0 42.9G 0 part sdb 8:16 0 74.5G 0 disk └─sdb1 8:17 0 74.5G 0 part /home/archive sdc 8:32 0 100M 0 disk └─mpatha 253:0 0 100M 0 mpath ├─mpatha1 253:1 0 50M 0 part └─mpatha2 253:2 0 49M 0 part sdd 8:48 0 100M 0 disk └─mpatha 253:0 0 100M 0 mpath ├─mpatha1 253:1 0 50M 0 part └─mpatha2 253:2 0 49M 0 part sde 8:64 0 100M 0 disk └─mpatha 253:0 0 100M 0 mpath ├─mpatha1 253:1 0 50M 0 part └─mpatha2 253:2 0 49M 0 part sdf 8:80 0 100M 0 disk └─mpatha 253:0 0 100M 0 mpath ├─mpatha1 253:1 0 50M 0 part └─mpatha2 253:2 0 49M 0 part De-duplicate by WWN: ./lsblk -M WWN NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT sda 8:0 0 223.6G 0 disk ├─sda1 8:1 0 200M 0 part /boot/efi ├─sda2 8:2 0 200M 0 part /boot ├─sda3 8:3 0 130.3G 0 part ├─sda4 8:4 0 50G 0 part / └─sda5 8:5 0 42.9G 0 part sdb 8:16 0 74.5G 0 disk └─sdb1 8:17 0 74.5G 0 part /home/archive sdc 8:32 0 100M 0 disk └─mpatha 253:0 0 100M 0 mpath ├─mpatha1 253:1 0 50M 0 part └─mpatha2 253:2 0 49M 0 part Addresses: https://github.com/karelzak/util-linux/issues/616 Signed-off-by: Karel Zak <kzak@redhat.com>

* lsblk: apply --nodeps to partitions tooKarel Zak2018-12-071-3/+3
| | | | | | | The new implementation differentiates between partitions and another dependences -- this is regression, we need root devices only. Signed-off-by: Karel Zak <kzak@redhat.com>

* lsblk: reuse 'removable' flag from parentKarel Zak2018-12-071-5/+29
| | | | | | | It's used in the default output, let's make it a little bit more effective. Signed-off-by: Karel Zak <kzak@redhat.com>
* lsblk: don't keep sysfs dirs openKarel Zak2018-12-071-16/+46
| | | | | | | Don't keep open sysfs file descriptors for all time to avoid problems on systems with huge number of block devices. Signed-off-by: Karel Zak <kzak@redhat.com>

* lsblk: add process_all_devices_inverse()Karel Zak2018-12-071-35/+90
| | | | | | | | | | | This is necessary to implement --inverse. Note that this new implementation scans /sys/dev/block/ to get top-level devices and than it calls process_one_device(). Note that standard non-inverse tree does not use process_one_device() as it's more effective to scan /sys/block where are no partitions. Signed-off-by: Karel Zak <kzak@redhat.com>
* lsblk: reorder functionsKarel Zak2018-12-071-56/+57
| | | | | | | The goal is to call process_one_device() from process_all_devices(), so let's it keep in code in the right order. Signed-off-by: Karel Zak <kzak@redhat.com>

* lsblk: split sysfs reading and scols table fillingKarel Zak2018-12-071-22/+56
| | | | | | | | | | | | | | | | | | This change allows read devices from sysfs only once and reuse device properties if the device is references more than once in the tree (RAIDs, etc.). * every device is in the tree only once (tree->devices list) * iterate_block_devices() reuse already read devices (for example if already read for any dependence) * the smartscols table is build from the final tree The patch temporary disables dependencies evaluation (in process_blkdev() to keep the patch small and simple.

* lsblk: rename blkdev_cxt to lsblk_deviceKarel Zak2018-12-071-232/+232
| | | | | | | | | The patch does not change code logic and semantic -- just rename. * set_cxt() to set_device() * struct blkdev_cxt to lsblk_device Signed-off-by: Karel Zak <kzak@redhat.com>
* lsblk: always use "part" as TYPE for partitionsKarel Zak2018-10-031-1/+4
| | | | | | | | | The current code uses "part" or "disk" only if nothing else is possible to recognize. It means for example partitions on loops (or RAIDs, etc) are marked as "loop" rather than "part".
