Samba client packet signature check error
Last modified: 2011-03-19 06:27:17 EDT
Description of problem:
I'm using fusesmb with options large_read and big_writes. When I ties to copy file to network share of windows server, which requires packet signing (Microsoft network server: Digitally sign communications = Enabled), copying fails and only 32KB of file copied. Strarting fusesmb with debug option showed me error:
unique: 652, opcode: WRITE (16), nodeid: 79, insize: 32848
write 32768 bytes to 0 flags: 0x8001
smb_signing_good: BAD SIG: seq 1
SMB Signature verification failed on incoming packet!
write 16384 bytes to 0
unique: 652, success, outsize: 24

If size of file is less than 32KB copy process vents OK.
When I switches packet signing off copy process vents OK.
When I mounts fusesmb without big_writes copy process vents OK too.
Same behaviour I observes if I copies files in KDE's dolphin file manager.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Turn on mandatory packet signing on windows server (Microsoft network server: Digitally sign communications (always) = Enabled in security policy/security options).
2. Mount windows shares using fusesmb -o large_read,big_writes or connect to share via dolphin.
3. Try to copy file (size > 32KB) to share.
Error occured and only 32KB of file copied.
File will copied OK.
Problem seems related to write segment size.
This package has changed ownership in the Fedora Package Database. Reassigning to the new owner of this component.
Can you please provide a packet trace of this issue ?
