[Bug 1192549] New: Kernel 5.3.18-lp152.98-default breaks getdents(2) system call on NFS shares
http://bugzilla.opensuse.org/show_bug.cgi?id=1192549 Bug ID: 1192549 Summary: Kernel 5.3.18-lp152.98-default breaks getdents(2) system call on NFS shares Classification: openSUSE Product: openSUSE Distribution Version: Leap 15.2 Hardware: x86-64 OS: openSUSE Leap 15.2 Status: NEW Severity: Critical Priority: P5 - None Component: Kernel Assignee: kernel-bugs@opensuse.org Reporter: werner@suse.com QA Contact: qa-bugs@suse.de Found By: --- Blocker: --- that is in the home directory of my own as well as of other users (beside /suse/present and /suse/bin) the simply command ls returns exactly nothing ... and strace show that the system call getdents(2) returns zero entries. Interesting I can e.g. change into ~/.fvwm/ or ~/.config/ or ~/.mozilla/ and list all therein ... only the topper up directory node remains empty -- You are receiving this mail because: You are the assignee for the bug.

In my case, only directories which contain a medium to large number of entries are shown as entirely empty on ls. I could not find out the exact amount from which on this behavior happens, perhaps the threshold between rdir and rdirplus. It's an on-off behavior: The content is shown entirely or not at all. No errors appear while mounting or accessing the directories neither in journal nor dmesg. I tried nfsv4 and v3 mounts and several options related to nfs caching without change, only the client is an opensuse machine. Files still remain accessible although not visible, if the name is known, so it clearly is related to directory listing only. Switching back to the "old" kernel 5.3.18-lp152.95 via bootloader remedies the error immediately for me too. Both kernel spices default and preempt are affected. -- You are receiving this mail because: You are the assignee for the bug.

I knew about this bug a couple of days ago, but forgot that I had pushed the patch to this kernel too - I was focused on SLE12-SP5 The dir_cookie is a pointer in our kernels and needs to be dereferenced. I've push a for-next with the patch fixed. It looks like I need to check SLE12-SP4 too. -- You are receiving this mail because: You are the assignee for the bug.

This kernel still is ok: vmlinuz-5.3.18-59.27-default uname -a Linux pluto 5.3.18-59.27-default #1 SMP Tue Oct 5 10:00:40 UTC 2021 (7df2404) x86_64 x86_64 x86_64 GNU/Linux The next one is not: vmlinuz-5.3.18-59.30-default A quick fix for this issue would be good, since the offending update is still delivered via automatic updates.
