Otto Kekäläinen added a comment - 2020-04-21 17:01 jplindst Why do you ask instead of checking it yourself? vagrant@ubuntu-focal:~$ sudo sysctl fs.protected_regular fs.protected_regular = 2   vagrant@ubuntu-focal:~$ sudo rm -f /tmp/xx vagrant@ubuntu-focal:~$ sudo touch /tmp/xx vagrant@ubuntu-focal:~$ sudo chmod 600 /tmp/xx vagrant@ubuntu-focal:~$ sudo chown $USER /tmp/xx vagrant@ubuntu-focal:~$ sudo sh -c "echo 1 > /tmp/xx" sh: 1: cannot create /tmp/xx: Permission denied   vagrant@ubuntu-focal:~$ sudo sysctl fs.protected_regular=0 fs.protected_regular = 0 vagrant@ubuntu-focal:~$ sudo sh -c "echo 1 > /tmp/xx"   vagrant@ubuntu-focal:~$ sudo sysctl fs.protected_regular=1 fs.protected_regular = 1 vagrant@ubuntu-focal:~$ sudo sh -c "echo 1 > /tmp/xx" sh: 1: cannot create /tmp/xx: Permission denied Can you jplindst please proceed and fix this everywhere in Galera? What Alexander did in MDEV-21140 was most likely not the only place where this is needed.

Otto Kekäläinen added a comment - 2020-04-21 19:36 Tentative fix in https://github.com/MariaDB/server/pull/1510 . I am doing this only for 10.5 and only for this one chown scenario in order to not get stalled with fixing the bugs I actually have assigned on my name and which I indend to have closed by the end of the month. Buildbot greenness is holy for me. I don't understand how anybody can develop without having CI that confirms all the time that no testable regressions exist... I at least can't. I leave it to Seppo or Jan to fix this properly.

Marko Mäkelä added a comment - 2020-04-22 14:12 I merged otto ’s 10.2 change to 10.3, and it does work there. I see that jplindst separately pushed a change to 10.5 without waiting for a merge.
