Could you attach gdb to start-stop-daemon and get a backtrace too?
I have the same issue as well, also only with samba. Haven't had to time to dig into it. openrc v0.51 (newest as of writing) affecting two seperate systems.
I have the same issue after upgrading to >=sys-kernel/gentoo-sources-6.6.0. It does not reproduce when I booted with <sys-kernel/gentoo-sources-6.6.0. It does not reproduce when I run `start-stop-daemon --stop --exec /usr/sbin/smbd` directly in a shell.

Interestingly, after the following sequence '/etc/init.d/samba stop' has hung and needs aborting with Ctrl/C, even though smbd & nmbd have already been stopped manually. <<<<< # /etc/init.d/samba start * samba -> start: smbd ...

Also reproduced in sys-kernel/gentoo-kernel-6.6.1 without `savedconfig`. (to confirm if the issue was caused by my kernel config.)
The plot thickens. While samba is running normally # ps -ef | grep -E "smbd|nmbd" root 7766 1 0 09:52 ? 00:00:00 /usr/sbin/smbd -D root 7771 7766 0 09:52 ? 00:00:00 smbd: notifyd . root 7772 7766 0 09:52 ? 00:00:00 smbd: cleanupd root 7774 1 0 09:52 ? 00:00:00 /usr/sbin/nmbd -D root 7794 7789 0 09:53 pts/13 00:00:00 grep --colour=auto -E smbd|nmbd After /etc/init.d/samba stop # ps -ef | grep -E "smbd|nmbd" root 7774 1 0 09:52 ? 00:00:00 /usr/sbin/nmbd -D root 7811 7796 86 09:53 pts/12 00:00:03 start-stop-daemon --stop --exec /usr/sbin/smbd root 7815 7789 0 09:53 pts/13 00:00:00 grep --colour=auto -E smbd|nmbd Note that smbd has been successfully stopped by the start-stop-daemon but it is still trying to delete the 'daemon info' but none of the files in /run/openrc/daemons/samba match smbd cat /run/openrc/daemons/samba/001 exec=/usr/sbin/nmbd argv_0=/usr/sbin/nmbd argv_1=-D pidfile= # cat /run/openrc/daemons/samba/002 exec=/usr/sbin/nmbd argv_0=/usr/sbin/nmbd argv_1=-D pidfile= Interestingly both files have the same inode number! In fact 'ls -li /run/openrc/daemons/samba/' reports the same inode number for all the files it finds.
I see the same problem with net-misc/xrdp as well. Running a test program doing something very similar to `rc_service_daemon_set` (scan directory, rename file) on tmpfs (this part is important; /run is tmpfs) gives the same infinite loop. Basically `rename` triggers re-reading new renamed file from `readdir` and calling rename again, infinitely.
The difference from other daemons appears to be this: $ ls /run/openrc/daemons/sshd/ 001 $ ls /run/openrc/daemons/samba/ 001 002 On my system, only samba and xrdp have two files in daemon directory. So for other daemons openrc doesn't attempt this rename.
I've created https://github.com/OpenRC/openrc/pull/668 that should fix that problem. Could you please test it with that patch: diff --git a/src/librc/librc-daemon.c b/src/librc/librc-daemon.c index 50245129..e23593b9 100644 --- a/src/librc/librc-daemon.c +++ b/src/librc/librc-daemon.c @@ -402,7 +402,7 @@ rc_service_daemon_set(const char *service, const char *exec, bool retval = false; DIR *dp; struct dirent *d; - RC_STRINGLIST *match; + RC_STRINGLIST *match, *renamelist; int i = 0; FILE *fp; @@ -416,11 +416,17 @@ rc_service_daemon_set(const char *service, const char *exec, /* Regardless, erase any existing daemon info */ if ((dp = opendir(dirpath))) { match = _match_list(exec, argv, pidfile); + renamelist = rc_stringlist_new(); while ((d = readdir(dp))) { if (d->d_name[0] == '.') continue; xasprintf(&file, "%s/%s", dirpath, d->d_name); + if (rc_stringlist_find(renamelist, file)) { + free(file); + continue; + } + nfiles++; if (!*oldfile) { @@ -432,11 +438,15 @@ rc_service_daemon_set(const char *service, const char *exec, } else { rename(file, oldfile); strlcpy(oldfile, file, sizeof(oldfile)); + /* Add renamed file to renamelist, as this new file name could + * be read again from readdir() */ + rc_stringlist_add(renamelist, oldfile); } free(file); } closedir(dp); rc_stringlist_free(match); + rc_stringlist_free(renamelist); } /* Now store our daemon info */
The patch works fine and start-stop-daemon stops smbd successfully. Thank you!
Same for me, patch fixes issues with samba & kea dhcp
Patch worked for me on sys-apps/openrc-0.48 with kernel 6.6.1.
just ftr/completeness, the relevant change I think is: commit a229cf67ab851a6e92395f37ed141d065176575a Merge: 5d2f53532ecc 8e7f82deb0c0 Author: Linus Torvalds <torvalds@linux-foundation.org> Date: Wed Sep 20 11:03:45 2023 -0700 Merge tag 'for-6.6-rc2-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux Pull btrfs fixes from David Sterba: "A few more followup fixes to the directory listing. People have noticed different behaviour compared to other filesystems after changes in 6.5. This is now unified to more "logical" and expected behaviour while still within POSIX.

Patch worked for me on sys-apps/openrc-0.51 with kernel 6.6.1.
This will be included in 0.52.
