File 0001-cgrulesengd-Do-not-ignore-changes-of-short-lived-pro.patch of Package libcgroup.11263
From 4cbedeae74ca5cfd1678ca8e8a29b5d65c3a87f1 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Michal=20Koutn=C3=BD?= <mkoutny@suse.com> Date: Mon, 18 Mar 2019 18:07:24 +0100 Subject: [PATCH] cgrulesengd: Do not ignore changes of short-lived processes When a double-forking daemon spawns the shortlived forking process and we fail to classify it in time, we cannot assume the child inherits cgroup membership. Instead we apply the logic introduced in 8953fc07c0498d1ddd9a04dc549ffb85862f4c5f assuming the parent would have changed its cgroup membership by out actions. --- src/daemon/cgrulesengd.c | 5 +++-- 1 file changed, 3 insertions(+), 2 deletions(-) diff --git a/src/daemon/cgrulesengd.c b/src/daemon/cgrulesengd.c index 0d288f3..f113b14 100644 --- a/src/daemon/cgrulesengd.c +++ b/src/daemon/cgrulesengd.c @@ -478,8 +478,9 @@ int cgre_process_event(const struct proc_event *ev, const int type) ret = cgroup_change_cgroup_flags(euid, egid, procname, pid, CGFLAG_USECACHE); if ((ret == ECGOTHER) && (errno == ESRCH)) { - /* A process finished already and that is not a problem. */ - ret = 0; + /* A process finished already but we may have missed changing, + * make sure to apply to forked children. */ + ret = cgre_store_parent_info(pid); } else if (ret) { flog(LOG_WARNING, "Cgroup change for PID: %d, UID: %d, GID: %d, PROCNAME: %s FAILED!
