084575ff91 test: use set -eux and set -o pipefail everywhere
This should make the scripts more robust.

4e20fe2795 TEST-*: make failure tests actually fail on failure
Here the intent was actually correct, and the tests still pass when the check
is made effective.

4e806bfa9f oom: add unit file settings for oomd avoid/omit xattrs 2021-02-12 12:45:36 -08:00

59331b8e29 oom: implement avoid/omit xattr support
There may be situations where a cgroup should be protected from killing
or deprioritized as a candidate. In FB oomd xattrs are used to bias oomd
away from supervisor cgroups and towards worker cgroups in container
tasks. On desktops this can be used to protect important units with
unpredictable resource consumption.

The patch allows systemd-oomd to understand 2 xattrs:
"user.oomd_avoid" and "user.oomd_omit". If systemd-oomd sees these
xattrs set to 1 on a candidate cgroup (i.e. while attempting to kill something)
AND the cgroup is owned by root, it will either deprioritize the cgroup as
a candidate (avoid) or remove it completely as a candidate (omit).

Usage is restricted to root owned cgroups to prevent situations where an
unprivileged user can set their own cgroups lower in the kill priority than
another user's (and prevent them from omitting their units from
systemd-oomd killing).

0a9f93443b oom: rework *MemoryPressureLimit= properties to have 1/10000 precision
Requested in
https://github.com/systemd/systemd/pull/15206#discussion_r505506657,
preserve the full granularity for memory pressure limits (permyriad)
instead of capping out at percent.

14d044da23 test: fix TEST-56-OOMD thresholds for linux 5.9 changes
Fixes #17533

The memory pressure values of the units in TEST-56-OOMD seemed to be a
lot lower after updating to linux 5.9. This is likely due to a fix from
e22c6ed90a.

To account for this, I lowered memory.high on testbloat.service to
throttle it even more. This was enough to generate the 50%+ value to trigger
oomd for the test, but as an extra precaution I also lowered the oomd
threshold to 1% so it's certain to try and kill testbloat.service.

e4ff80404a test: add basic memory pressure extended test for oomd
Simple test to generate a lot of pressure in one unit and assert that
systemd-oomd kills the right one.
