[Bug 1935051] Re: systemd pid 1 memory leak
** Description changed:
+ [impact]
+
+ pid1 leaks memory when rebuilding unit path cache
+
+ [test case]
+
+ see original description.
+
+ also, the patch contains an example of how to reproduce:
+
+ $ for i in {1..300}; do cp ~/.config/systemd/user/test0001.service
+ ~/.config/systemd/user/test$(printf %04d $i).service; systemctl --user
+ start test$(printf %04d $i).service;done
+
+ [regression]
+
+ any problems would occur when rebuilding the path cache, possibly
+ resulting in memory leaks or pid1 crashes.
+
+ [scope]
+
+ this is needed only in f
+
+ fixed upstream by 3fb2326f3ed87aa0b26078d307ebfb299e36286d which is
+ included in v246, so fixed in h and later
+
+ the code in b is very different and doesn't appear to have the leak, per
+ original report
+
+ [original description]
+
Hi everybody.
We've meet a memory leak of pid1 process on the focal release.
When we launch chef-client, several systemd .service and .timers are checked
for state.
Every time of this run pid1 increase VSZ/RSS on ~ 232 Kb, this don't happen
on xenial and bionic releases.
I straced pid1 when that leak happen and found brk call.
On pmap view of pid 1 it's anon memory grow on the same address and all
marked as dirty.
All that leak memory can be freed by calling systemctl daemon-reexec.
Searching in systemd github repo i found this commit
https://github.com/systemd/systemd/commit/3fb2326f3ed87aa0b26078d307ebfb299e36286d
- it may be related to this leak.
