kernel .55 has been released after 22/Mar/2023 as reported by uname:
# uname -a Linux <hostname> 5.14.21-150400.24.55-default #1 SMP PREEMPT_DYNAMIC Mon Mar 27 15:25:48 UTC 2023 (cc75cf8) x86_64 x86_64 x86_64 GNU/Linux
Unfortunately this release doesn't contain the fix. It was released Mar 27, but only includes patches submitted up to Mar 21. So the fix I submitted the next day missed out :-( I think another update is expected in a week or so.
Is it the correct release date? If so, maybe the fix occurred later? I'll try to dig in https://github.com/SUSE/kernel/tree/SLE15-SP4 ...
As mentioned here https://forum.qnap.com/viewtopic.php?f=35&t=165385 , a workaround is to force the protocol version to 4:
# mount -t nfs nas:/Web /mnt/tmp/ => FAILS # mount -o nfsvers=4 -t nfs nas:/Web /mnt/tmp/ => OK # mount -o nfsvers=4.0 -t nfs nas:/Web /mnt/tmp/ => OK
Yes, the QNAP bug only triggers for NFS version 4.1 and later I'm sorry about this. The patch which trigger the bug only landed in SLE very recently as a bugfix for another problem. I actually knew about the problem with QNAS, but I didn't put 2 and 2 together when I was processing a set of bugfixes from upstream into our SUSE kernels. I should have caught it and made sure the fix-for-the-fix landed at the same time. But I didn't. Sorry. -- You are receiving this mail because: You are on the CC list for the bug.
