# v3 -> v4

* Fix typos.
* Update commit message for the indentation patch.
* Added Andrii's acks.

# v2 -> v3

* Added missing tags.
* Indentation fixes + some other fixes suggested by Andrii.
* Re-indent file to tabs.

The selftest for the bpf_ima_inode_hash helper uses a shell script to
setup the system for ima. While this worked without an issue on recent
desktop distros, it failed on environments with stripped out shells like
busybox which is also used by the bpf CI.

This series fixes the assumptions made on the availablity of certain
command line switches and the expectation that securityfs being mounted
by default.

It also adds the missing kernel config dependencies in
tools/testing/selftests/bpf and, lastly, changes the indentation of
ima_setup.sh to use tabs.

KP Singh (4):
  selftests/bpf: Update ima_setup.sh for busybox
  selftests/bpf: Ensure securityfs mount before writing ima policy
  selftests/bpf: Add config dependency on BLK_DEV_LOOP
  selftests/bpf: Indent ima_setup.sh with tabs.

losetup on busybox does not output the name of loop device on using
-f with --show. It also doesn't support -j to find the loop devices
for a given backing file. losetup is updated to use "-a" which is
available on busybox.

blkid does not support options (-s and -o) to only display the uuid, so
parse the output instead.

Not all environments have mkfs.ext4, the test requires a loop device
with a backing image file which could formatted with any filesystem.
Update to using mkfs.ext2 which is available on busybox.

SecurityFS may not be mounted even if it is enabled in the kernel
config. So, check if the mount exists in /proc/mounts by parsing the
file and, if not, mount it on /sys/kernel/security.

The ima selftest restricts its scope to a test filesystem image
mounted on a loop device and prevents permanent ima policy changes for
the whole system.

The file was formatted with spaces instead of tabs and went unnoticed
as checkpatch.pl did not complain (probably because this is a shell
script). Re-indent it with tabs to be consistent with other scripts.

Thanks, I think this reads much better. And a few months from now it
would be easier to understand and page back the context, if necessary.

I've pushed your fixes. ima selftest still emits a bunch of extra
output from dd and maybe other commands:

10+0 records in
10+0 records out
10485760 bytes (10.0MB) copied, 0.037096 seconds, 269.6MB/s
Filesystem label=
OS type: Linux
Block size=1024 (log=0)
Fragment size=1024 (log=0)
2560 inodes, 10240 blocks
512 blocks (5%) reserved for the super user
First data block=1
Maximum filesystem blocks=262144
2 block groups
8192 blocks per group, 8192 fragments per group
1280 inodes per group
Superblock backups stored on blocks:
        8193

Please follow up at your earliest convenience to silence those in
default (non-verbose) mode.
