Bug#1099591: linux-image-6.12.12-amd64: crash in netfs module when copying (large) directory from smb share
Package: src:linux
Version: 6.12.12-1
Severity: important
X-Debbugs-Cc: nolange79@gmail.com
Dear Maintainer,
I experience an immediate Kernel Crash when copying large files/directories from
a mounted Samba share.
I can consistently reproduce the crash in Qemu (from which I grabbed the Log).
My content of `/etc/fstab`:
```
//vienas01.andritz.com/HIPASE /run/media/HIPASE_Q smb3 credentials=/tmp/creds.txt,uid=1000,user,vers=3,nofail,noatime,noauto 0 0
```
The sequence leading to the crash is a filecopy to local HDD:
``` bash
mount /run/media/HIPASE_Q
cp -r /run/media/HIPASE_Q/DIR ~/Download
```
Output from mount is:
```
//vienas01.andritz.com/HIPASE on /run/media/HIPASE_Q type smb3 (rw,nosuid,nodev,relatime,vers=3.1.1,cache=strict,username=XXX,domain=YYY,uid=1000,forceuid,gid=1000,forcegid,addr=172.24.180.161,file_mode=0755,dir_mode=0755,soft,nounix,serverino,mapposix,reparse=nfs,rsize=65536,wsize=65536,bsize=1048576,retrans=1,echo_interval=60,actimeo=1,closetimeo=1,user=XXX)
```
The crash is diagnosed as follows (again, under Qemu with the same kernel):
