charset="us-ascii" Content-Transfer-Encoding: 7bit Sender: devel-bounces@openvz.org Errors-To: devel-bounces@openvz.org Since 22.4 CRIU fails to dump a container which is close to its mount limit: Error (criu/mount.c:1740): mnt: Unable to unshare a mount namespace: Cannot allocate memory To get access to overmounted mounts, CRIU (in ve0) copies the container mount namespace. The copied mounts are owned by and charged to the container, and now the container limit is also checked for them, so the host is restricted by the container limit. Patch 1 relaxes the limit for ve0 (still counting, as for pseudosuper), patch 2 adds a selftest for it. https://virtuozzo.atlassian.net/browse/VSTOR-147661 Signed-off-by: Pavel Tikhomirov --- Pavel Tikhomirov (2): ve/fs: allow host to go over limit of container mount namespace selftests/ve: check that host can go over container mount limit fs/namespace.c | 3 +- .../selftests/ve/ve_mount_accounting_test.c | 37 ++++++++++++++++++++++ 2 files changed, 39 insertions(+), 1 deletion(-) --- base-commit: ca54f152160587a74ff17cb52feef16f7b9d4e2b change-id: 20260928-b4-ve0-mnt-limit-5bdc176203a4 Best regards, -- Pavel Tikhomirov _______________________________________________ Devel mailing list Devel@openvz.org https://lists.openvz.org/mailman/listinfo/devel
