Hi Paulo
Thanks for answer and help
I'll look into it as soon as I recover from my illness.
Hope you're doing better
I had to rollback to linux 6.13.8 to be able to use the SMB share and
here is what I constat
(don't know if it's a normal behavior but if yes, SMB seems to be a very
very unefficient protocol)
I think the issue can be buffer related:
On Linux 6.13.8 the copy and cat of the 5 bytes 'toto' file containing
only ascii string 'toto' is working fine but here is what I capture with
tcpdump during transfert of toto file:
https://xba.soartist.net/t6.pcap
131 tcp packets to transfer a 5 byte file...
Isn't there a problem ?
Openning the pcap file with wireshark show a lot of lines:
25 0.005576 10.0.10.100 10.0.10.25 SMB2 1071 Read Response, Error:
STATUS_END_OF_FILE
It seems that those lines appears after the 5 bytes 'toto' file had been
transferred, and it continue until the last ACK recieved
I will try to reboot on Linux 6.14.0 mainline to see if I have the same
behavior or to see what I get in the packet capture
(system is in production, I cannot reboot on a failing kernel when I
want, it should be organised... sorry)
Let me know if you reproduced the issue
Kind regards

Did someone reproduced the issue (very easy) ?
CIFS SHARE is mounted as /mnt/fbx/FBX-24T
echo toto >/mnt/fbx/FBX-24T/toto
