Bug#764162: linux-image-3.16-2-kirkwood: [regression 3.14->3.16] file data corruption, via network
Package: src:linux
Version: 3.16.3-2
Severity: serious
Justification: may cause silent data corruption
Hello,
after upgrading the kernel of my NAS to 3.16-2-kirkwood, I noticed
corrupt data on my files. The NAS works as a DHCP client on its single
LAN port, the two hard drives run in a RAID1 configuration. Both
drives are fine according to mdadm and smartctl. Kernel logs in both
cases have not been eye-catching. Samba is configured with "unix
charset = ISO-8859-1".
When copying data from the NAS to some other device using CIFS or
Samba (the other devices run jessie/amd64 or wheezy/i686), the files
are partly corrupt. The reported md5 checksums of files change every
time the files are read. (And they differ from the checksums as stored
on disk as well.) The files are not completely destroyed: ZIP archives
show CRC errors only for some files in them, and video files remain
generally playable, with lots of audio/video errors and crashing
players.
Shell access using SSH generally works. Trying to copy files with scp
or sftp breaks the connection ("invalid MAC packets" or similar). File
listing and mounting with sshfs work. Trying to copy files via sshfs
results in a "Socket not connected" error, and the mount point is
gone.
As far as I can see, the on-disk data seems to be fine, as do files
copied to the NAS while running the corrupt kernel. I am unable to
check all new files, though - there might have been silent data
corruption on new files.
Data corruption on NAS devices is a serious issue for me.
Reverting back to 3.14-2-kirkwood fixed the problems.
Best Regards
