* hack/test/utils: switch to golang native error wrappingSascha Grunert2022-07-05
| | | | | | | | | We now use the golang error wrapping format specifier `%w` instead of the deprecated github.com/pkg/errors package. [NO NEW TESTS NEEDED] Signed-off-by: Sascha Grunert <sgrunert@redhat.com>

| | | | | | | if we are running on cgroupv2, force the creation of a sub-cgroup even when we are at the root for the cgroup v2 unified mount. Signed-off-by: Giuseppe Scrivano <gscrivan@redhat.com>

* utils: reintroduce moveToCgroupGiuseppe Scrivano2021-12-08
| | | | | | | | | | | | | | | commit ee62711136339c5daf38e38859227d85b06fc32a introduced the regression. It was mistakenly removed as part of a cleanup, but this code is needed by another code path, where we move conmon for the exec session to the same cgroup used by conmon for the process. Closes: https://github.com/containers/podman/issues/12535 [NO NEW TESTS NEEDED] it fixes a regression in the CI Signed-off-by: Giuseppe Scrivano <gscrivan@redhat.com>
* Update vendor or containers/common moving pkg/cgroups thereDaniel J Walsh2021-12-07
| | | | | | | [NO NEW TESTS NEEDED] This is just moving pkg/cgroups out so existing tests should be fine. Signed-off-by: Daniel J Walsh <dwalsh@redhat.com>
* utils: use podman-pause-$RANDOM.scope nameGiuseppe Scrivano2021-11-17
| | | | | | | | | | | | | | | we try hard to re-use the existing podman-pause.scope name when it already exists, causing any sort of race errors when the already existing scope is terminating. There is no such a requirement though, so just try with a random name. Closes: https://github.com/containers/podman/issues/12065 [NO NEW TESTS NEEDED] it fixes a race in the CI Signed-off-by: Giuseppe Scrivano <gscrivan@redhat.com>

| | | | | | | | | | Make sure we close our private connection to the bus, even if we're not successful in in using it to ask systemd to move a unit's processes to a specific control group. [NO TESTS NEEDED] Signed-off-by: Nalin Dahyabhai <nalin@redhat.com>
* utils: move message from warning to debugGiuseppe Scrivano2021-06-16

* utils: takes the longest path on cgroup v1Giuseppe Scrivano2021-02-11
| | | | | | | | | | | | | | | | | | | | | | now getCgroupProcess takes the longest path on cgroup v1, instead of complaining if the paths are different. This should help when --cgroups=split is used on cgroup v1 and the process cgroups look like: $ cat /proc/self/cgroup 11:pids:/user.slice/user-0.slice/session-4.scope 10:blkio:/ 9:cpuset:/ 8:devices:/user.slice 7:freezer:/ 6:memory:/user.slice/user-0.slice/session-4.scope 5:net_cls,net_prio:/ 4:hugetlb:/ 3:cpu,cpuacct:/ 2:perf_event:/ Signed-off-by: Giuseppe Scrivano <gscrivan@redhat.com>

* podman, exec: move conmon to the correct cgroupGiuseppe Scrivano2020-12-03
| | | | | | | | | | | | move the conmon process to the conmon cgroup also on exec. The previous implementation would fail to move the conmon process as the systemd unit already exists so its creation would fail. When the unit cannot be created, attempt to directly join the cgroup instead. Signed-off-by: Giuseppe Scrivano <gscrivan@redhat.com>
* Remove excessive error wrappingKir Kolyshkin2020-10-05
| | | | | | | | | | | | | | | | | In case os.Open[File], os.Mkdir[All], ioutil.ReadFile and the like fails, the error message already contains the file name and the operation that fails, so there is no need to wrap the error with something like "open %s failed". While at it - replace a few places with os.Open, ioutil.ReadAll with ioutil.ReadFile. - replace errors.Wrapf with errors.Wrap for cases where there are no %-style arguments.

* move go module to v2Valentin Rothberg2020-07-06
| | | | | | | | | | | | | | | With the advent of Podman 2.0.0 we crossed the magical barrier of go modules. While we were able to continue importing all packages inside of the project, the project could not be vendored anymore from the outside. Move the go module to new major version and change all imports to `github.com/containers/libpod/v2`. The renaming of the imports was done via `gomove` [1].

* utils: fix parsing of cgroup with : in the nameGiuseppe Scrivano2020-06-30
| | | | | | | | | a cgroup can have ':' in its name. Make sure the parser doesn't split more than 3 fields and leave untouched the ':' in the cgroup name. commit 6ee5f740a4ecb70636b888e78b02065ee984636c introduced the issue. Signed-off-by: Giuseppe Scrivano <gscrivan@redhat.com>
* podman: add new cgroup mode splitGiuseppe Scrivano2020-06-25
| | | | | | | | | | | | | | | | | | | When running under systemd there is no need to create yet another cgroup for the container. With conmon-delegated the current cgroup will be split in two sub cgroups: - supervisor - container The supervisor cgroup will hold conmon and the podman process, while the container cgroup is used by the OCI runtime (using the cgroupfs backend).
