Re: [netfs/cifs - Linux 6.14] loop on file cat + file copy when files are on CIFS share

[Nicolas Baranger <nicolas.baranger@3xo.fr>]

Hi Christoph

Thanks for answer and help
Did someone reproduced the issue (very easy) ?


CIFS SHARE is mounted as /mnt/fbx/FBX-24T
echo toto >/mnt/fbx/FBX-24T/toto

ls -l /mnt/fbx/FBX-24T/toto
-rw-rw-rw- 1 root root 5 20 mars  09:20 /mnt/fbx/FBX-24T/toto

cat /mnt/fbx/FBX-24T/toto
toto
toto
toto
toto
toto
toto
toto
^C


CIFS mount options:
grep cifs /proc/mounts
//10.0.10.100/FBX24T /mnt/fbx/FBX-24T cifs 
rw,nosuid,nodev,noexec,relatime,vers=3.1.1,cache=none,upcall_target=app,username=fbx,domain=HOMELAN,uid=0,noforceuid,gid=0,noforcegid,addr=10.0.10.100,file_mode=0666,dir_mode=0755,iocharset=utf8,soft,nounix,serverino,mapposix,mfsymlinks,reparse=nfs,nativesocket,symlink=mfsymlinks,rsize=65536,wsize=65536,bsize=16777216,retrans=1,echo_interval=60,actimeo=1,closetimeo=1
