Bug#623059: Data corruption when sendfile is used on atl1c Atheros NIC.

But you should fix this (and use compiler options -Wall and -Wextra). Thanks for noticing it. The extra data at the start of 'apache.dat' and 'sendfile.dat' looks like the packet headers, so for some reason they have been duplicated. Please can you test the attached patch, following the instructions at http://kernel-handbook.alioth.debian.org/ch-common-tasks.html#s-common-official? Unfortunately I'll be able to test it after May 10th. So, if you already have a report that the issue has been fixed, that's fine be me.

Bug#623059: Data corruption when sendfile is used on atl1c Atheros NIC.
Package: linux-2.6 Version: 2.6.32-33 Severity: grave File: /lib/modules/2.6.32-5-686-bigmem/kernel/drivers/net/atl1c/atl1c.ko Hello, As far as I can tell it there is the bug occuring when combination of sendfile(2) and module atl1c is used. The result of the bug is data corruption. Examples of data corruption are in attached files: - orig.txt - the original file, output of command seq 1 600 | xargs printf '%04d\n' - apache.dat - result of wget http://the.server/orig.txt -O apache.dat - sendfile.dat - file sent from the same server using attached program and netcat The mentioned server has a multiple interfaces and this problem appears only on Atheros interface. After spotting the problem on Apache first I finally nailed it to sendfile function. The problem appears only for files longer than some specific value. For Apache it was 2600 bytes (I suppose it's because of headers added by webserver). For my test program the minimal size of file where the problem appears is 2896 bytes. I also found a similar problem on Ubuntu: https://bugs.launchpad.net/ubuntu/+source/slide-webdavclient/+bug/651004 The common factor is Atheros AR8131.

I am wondering if the reclassification made by /etc/udev/rules.d/udev.rules is correct, given that the kenrel doesn't seem to think that the tun module (i.e. the tun module itself doesn't think) that tun is a net module. Look at http://bugs.debian.org/129968, maybe it would give you a hint. BTW, I placed 01tun.rules file with content: KERNEL=tun, NAME=misc/%k, SYMLINK=net/%k and this annoying message does not appear anymore. It looks for me that hotplug should have an exception for net/tun (but not net/tun?*) class and serve it as a misc device instead net. Am I right?
