From aae3c9a0753d32cbc366e7834cb29c2b7e2c8fcf Mon Sep 17 00:00:00 2001 From: Krayushkin Konstantin Date: Fri, 31 May 2019 11:16:17 +0300 Subject: [PATCH] coredump: fixed bug - some coredump temp files could be lost If the machine was suddenly shutted down (hard reboot for example) while processing core dump, temp files created manually (not with a O_TEMPFILE flag) stay in the system. After reboot systemd-coredump treat them as usual files, so they wouldn't be rotated and shall pollute the filesystem. Solution is to simply add those temp files to systemd-tmpfiles configs. --- tmpfiles.d/systemd-tmp.conf | 5 +++++ 1 file changed, 5 insertions(+) diff --git a/tmpfiles.d/systemd-tmp.conf b/tmpfiles.d/systemd-tmp.conf index beb77dd0e0..d47d468fba 100644 --- a/tmpfiles.d/systemd-tmp.conf +++ b/tmpfiles.d/systemd-tmp.conf @@ -16,3 +16,8 @@ X /var/tmp/systemd-private-%b-*/tmp # Remove top-level private temporary directories on each boot R! /tmp/systemd-private-* R! /var/tmp/systemd-private-* + +# Handle lost systemd-coredump temp files.
