From 22f9510b92c92846484eda2ebdbaa75fdee2930b Mon Sep 17 00:00:00 2001 From: Hamza El-Saawy Date: Wed, 13 Aug 2025 10:59:33 -0400 Subject: [PATCH 1/2] [ms/release/0.1]Backport annotation, vNUMA, and GPU device changes (#2493) * Organize annotations; change annotation expansions. (#2449) Break out `pkg\annotations\annotations.go` constants into sections for easier searching and readability. Deprecate `AnnotationExpansions` and instead provide `AnnotationExpansionMap()`, which returns the same value, but provides a new copy every call, so the `map` cannot be modified. Cannot delete it or change its type, since it is technically public. Signed-off-by: Hamza El-Saawy (cherry picked from commit ffcf48b3761d0979ad0c616de2e8348f252bf7a7) Signed-off-by: Hamza El-Saawy * Warn on incomplete vNUMA setting, clarify field names (#2466) Warn if vNUMA is not completely specified in uVM creation options, as this is likely a user error. Rename `"uvm".Opts.MaxSizePerNode` to `MaxMemorySizePerNumaNode` and clarify that it is measured in MiB. Similarly, rename `"annotations".NumaMaximumSizePerNode` to `NumaMaximumMemorySizePerNode`. Format `prepareVNumaTopology` doc comment to display appropriately. Related: switch to using `"logrus".IsLevelEnabled` rather than explicit logging level comparison, and fix bug where `--debug` flag was not added to runc if logging level is greater than `Debug` (i.e., `Trace`). Signed-off-by: Hamza El-Saawy (cherry picked from commit 0842153594e01fac1149635cd1ee24aad6153610) Signed-off-by: Hamza El-Saawy * Fix CUDA for non-privileged containers (#2492) CUDA initialization for GPUs fails for non-privileged containers. Experimenting shows that adding `rw` for all character devices fixes the error, so expand the [default `c *:* m` permissions](https://github.com/opencontainers/runc/blob/6bae6cad4759a5b3537d550f43ea37d51c6b518a/libcontainer/specconv/spec_linux.go#L205-L222) to `c *:* rwm`. Add `"gpu"` string constant and streamline device assignment logic.

Signed-off-by: Hamza El-Saawy (cherry picked from commit d3ffbb6134b34aa1985fa7c682694265c162157e) Backport PR #2506 Fix/Disable failing CI tests Unit test `TestGcsWaitProcessBridgeTerminated` and the functional test `TestHostProcess_whoami` keeps failing intermittently on our github CI test runs. That blocks us from merging our PRs. This commit fixes the race condition in the `TestGcsWaitProcessBridgeTerminated` test by adding a small sleep. The other test failure is probably more related to the test environment than the test itself. That will require additional investigations to fix the test, so the test is currently disabled.
