[Bug 2033892] Re: ls -l triggers mount of autofs shares when --ghost option is present or browse_mode is enabled
This bug was fixed in the package coreutils - 8.32-4.1ubuntu1.2 --- coreutils (8.32-4.1ubuntu1.2) jammy; urgency=medium * Fix an issue where running 'ls -l' on an autofs mount with '--ghost' or 'browse_mode=yes' enabled causes the mount to be attempted, even when the underlying storage is not available. This changes behaviour of ls back to what it was previously, before statx was introduced in 8.32.

For dotnet6 on amd64 and arm64, the errors are unrelated to coreutils
(the same test errors happen against dotnet6 itself and even glibc),
thus triggered a migration-reference/0 run.

[Bug 2033892] Re: ls -l triggers mount of autofs shares when --ghost option is present or browse_mode is enabled
Performing verification for Jammy I set up two Jammy VMs, one a nfs-server and the other an autofs/nfs- client. The client is using coreutils 8.32-4.1ubuntu1.1 from -updates. $ apt-cache policy coreutils | grep Installed Installed: 8.32-4.1ubuntu1.1 I set up the nfs server and autofs mounts as the Testcase indicates. $ ls -l ls: cannot access 'export-missing': No such file or directory total 4 drwxr-xr-x 3 root root 4096 Mar 20 22:16 export d? ? ?? ?? export-missing $ mount -l | grep mnt2 /etc/auto.indirect on /mnt2 type autofs (rw,relatime,fd=6,pgrp=692,timeout=300,minproto=5,maxproto=5,indirect,pipe_ino=21588) 192.168.122.65:/export on /mnt2/export type nfs (rw,relatime,vers=3,rsize=524288,wsize=524288,namlen=255,hard,proto=tcp,timeo=600,retrans=2,sec=sys,mountaddr=192.168.122.65,mountvers=3,mountport=47718,mountproto=udp,local_lock=none,addr=192.168.122.65) The mounts were previously unmounted, but when I issue 'ls -l', the mounts occur, which is not wanted, and we error out on the non-existant export-missing mount. I then enabled -proposed, and installed coreutils 8.32-4.1ubuntu1.2. $ apt-cache policy coreutils | grep Installed Installed: 8.32-4.1ubuntu1.2 From there, lets try the 'ls -l': $ ls -l total 0 drwxr-xr-x 2 root root 0 Mar 20 22:25 export drwxr-xr-x 2 root root 0 Mar 20 22:25 export-missing $ mount -l | grep mnt2 /etc/auto.indirect on /mnt2 type autofs (rw,relatime,fd=6,pgrp=648,timeout=300,minproto=5,maxproto=5,indirect,pipe_ino=16856) This time the mounts do not occur, we just get a listing of the possible autofs mounts. We can confirm with 'mount -l' that nothing was actually actioned. The package in -proposed fixes the issues.

[Bug 2033892] Re: ls -l triggers mount of autofs shares when --ghost option is present or browse_mode is enabled
Hello René, or anyone else affected, Accepted coreutils into jammy-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/coreutils/8.32-4.1ubuntu1.2 in a few hours, and then in the -proposed repository. Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how to enable and use -proposed. Your feedback will aid us getting this update out to other Ubuntu users. If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested, what testing has been performed on the package and change the tag from verification-needed- jammy to verification-done-jammy. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification- failed-jammy. In either case, without details of your testing we will not be able to proceed. Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in advance for helping! N.B. The updated package will be released to -updates after the bug(s) fixed by this package have been verified and the package has been in -proposed for a minimum of 7 days. ** Changed in: coreutils (Ubuntu Jammy) Status: In Progress => Fix Committed ** Tags added: verification-needed verification-needed-jammy -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2033892 Title: ls -l triggers mount of autofs shares when --ghost option is present or browse_mode is enabled To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/coreutils/+bug/2033892/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 2033892] Re: ls -l triggers mount of autofs shares when --ghost option is present or browse_mode is enabled
Considerations for the SRU team: I confirmed that the behavior in Jammy is different than Focal and Mantic, the previous / next supported releases. (Steps in the next comment.) So, although this SRU changes behavior in a stable release (generally not OK in SRUs), it is actually Jammy that changed behavior _across_ stable releases (and to a buggy one!). Thus, the SRU is reasonably _restoring_ (arguably, _fixing_) the _expected_ behavior. So, this looks OK for SRU, IMHO. Additionally, I considered two points before sponsoring this. 1) The impact of the code changes to non-autofs/non-automount: And it seems virtually zero, considering the man pages explain the flag now used in statx() is used in other related syscalls (stat, lstat, fstatat), which have it implied since Linux 4.11. And it indeed only affects automount (note the flag name). So, even though this change is "new" in Jammy, it's been tested in older and later releases for a long time (pre-Bionic kernels). stat(2): AT_NO_AUTOMOUNT (since Linux 2.6.38) [...] Since Linux 4.11 this flag is implied. statx(2): AT_NO_AUTOMOUNT [...] All of stat(2), lstat(2), and fstatat(2) act as though AT_NO_AUTOMOUNT was set. 2) Whether users may have started to rely on this behavior I agree this is unlikely, and think so because of 3 points: 2.1) This behavior did not exist in previous releases, which reduces the chances it has been 'learned' before. 2.2) The usage of autofs/automount rely on access to be made _to a particular mountpoint_ in order for it to be _mounted_. This is reflected in different documentation sources online, so it is likely that this is the way that has been 'learned'. 2.3) The safe side is, _even if_ an user started to rely on this behavior to automount the subdirs, the very next thing they will do (if they actually need that subdir mounted) is to _access_ that subdir - which can mount it just as before! -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2033892 Title: ls -l triggers mount of autofs shares when --ghost option is present or browse_mode is enabled To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/coreutils/+bug/2033892/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
