Which bittorrent client might that be? I don't have a lot of interest in corrupting my filesystem.

A gnarly 2.6.19 file corruption bug

IIRC from the reporter, the bug corrupts only the downloaded file, and the bittorent client finds the error (wrong checksum). So it should not got unnoticed, and it doesn't corrupt other files.

Looking at the link to Linus' testcase, it seems to be 'rtorrent'.

"Btw, here's a simpler test-program that actually shows the difference
between 2.6.18 and 2.6.19 in action, and why it could explain why a
program like rtorrent might show corruption behavious that it didn't show
before."

rtorrent

rtorrent is a very nice program.

I've also found that it's a great burn-in for a system. It's really good at testing ram, cpu and network (for lots of "light" connections). Apparently it can be a good filesystem test too!

Ah, I suspected as much. I use that program regularly, and it makes heavy use of mmap.

I guess I'll move back to 2.6.18 for now.

Note that the Debian and Ubuntu (apparently) 2.6.18 kernels have the same problem. Maybe other distributions as well.
But I guess there will be a fixed 2.6.18 kernel coming in any day now.

Ubuntu does not use 2.6.18 nor 2.6.19, so Ubuntu users are safe AFA this bug is concerned.

  • Edgy: 2.6.17
  • Feisty: 2.6.20
