The autobuild test system (on sn-devel-144) has detected an intermittent failing test in the current master tree.
The autobuild log of the failure is available here: http://git.samba.org/autobuild.flakey.sn-devel-144/2017-05-01-1233/flakey.log The samba build logs are available here: http://git.samba.org/autobuild.flakey.sn-devel-144/2017-05-01-1233/samba.stderr http://git.samba.org/autobuild.flakey.sn-devel-144/2017-05-01-1233/samba.stdout The top commit at the time of the failure was: commit 37ef28794c66238f2ae55936b680617bda3b1c1d Author: Ralph Boehme <[email protected]> Date: Fri Apr 28 11:33:24 2017 +0200 Revert "lib/util: make use of tfork in samba_runcmd_send()" This reverts commit 292e46ab12d8ec172c9d3b26330d8d6028a1d5a5. Processes run by tfork will have a parent pid of 1, they won't be childs of the caller anymore. When the source4 samba process uses samba_runcmd_send() to launch smbd and winbindd the resulting process hierarchy becomes: PPID PID PGID SID TTY TPGID STAT UID TIME COMMAND 1 516 510 510 ? -1 S 111 0:02 avahi-daemon: running [samba-ad.local] 1 29209 29209 29209 ? -1 Ss 0 0:00 ./bin/samba 29209 29210 29209 29209 ? -1 S 0 0:00 \_ ./bin/samba 29209 29211 29209 29209 ? -1 S 0 0:00 \_ ./bin/samba 29209 29213 29209 29209 ? -1 S 0 0:00 \_ ./bin/samba 29209 29215 29209 29209 ? -1 S 0 0:00 \_ ./bin/samba 29209 29216 29209 29209 ? -1 R 0 0:00 \_ ./bin/samba 29209 29217 29209 29209 ? -1 S 0 0:00 \_ ./bin/samba 29209 29218 29209 29209 ? -1 S 0 0:00 \_ ./bin/samba 29209 29220 29209 29209 ? -1 S 0 0:00 \_ ./bin/samba 29209 29221 29209 29209 ? -1 S 0 0:00 \_ ./bin/samba 29209 29222 29209 29209 ? -1 S 0 0:00 \_ ./bin/samba 29209 29223 29209 29209 ? -1 S 0 0:00 \_ ./bin/samba 29209 29224 29209 29209 ? -1 S 0 0:00 \_ ./bin/samba 29209 29225 29209 29209 ? -1 S 0 0:00 \_ ./bin/samba 1 29214 29209 29209 ? -1 S 0 0:00 ./bin/samba 29214 29219 29219 29219 ? -1 Ss 0 0:00 \_ /home/slow/git/samba/scratch/bin/smbd -D --option=server role check:inhibit=yes --foreground 29219 29236 29219 29219 ? -1 S 0 0:00 \_ /home/slow/git/samba/scratch/bin/smbd -D --option=server role check:inhibit=yes --foreground 29219 29237 29219 29219 ? -1 S 0 0:00 \_ /home/slow/git/samba/scratch/bin/smbd -D --option=server role check:inhibit=yes --foreground 29219 29238 29219 29219 ? -1 S 0 0:00 \_ /home/slow/git/samba/scratch/bin/smbd -D --option=server role check:inhibit=yes --foreground 1 29228 29209 29209 ? -1 S 0 0:00 ./bin/samba 29228 29230 29230 29230 ? -1 Ss 0 0:00 \_ /home/slow/git/samba/scratch/bin/winbindd -D --option=server role check:inhibit=yes --foreground 29230 29239 29230 29230 ? -1 S 0 0:00 \_ /home/slow/git/samba/scratch/bin/winbindd -D --option=server role check:inhibit=yes --foreground They will still be in the same process group and session, but just not be a child or subchild. For childs of the source4 samba process this might be non desirable. killing all processes by sending a signal to the main samba process still works, because a pipe is used between the samba process and the smbd and winbindd childs. Both watch for EOF on the pipe. In the output above smbd and winbindd are in their own process group ans session because they call become_daemon().
