| |
I'm really short on time right now, so this bug report might be vague, but it's important enough for me to try:
I have an NFS fileserver (running 2.6.0-test4-mm1) exporting stuff from three filesystems: ReiserFS, ext3, and XFS. I'm seeing no problems with my ReiserFS and ext3 filesystems. XFS is a different story.
My client machine is running 2.4.21bkn1 (my own kernel, not released to the public; the differences from vanilla 2.4.21 are XFS and Win4Lin).
If I use my client machine to sign RPM packages (rpm --addsign ...), using rpm-4.2-16mdk, and the packages are on the XFS partition on the NFS server, about half of the packages are truncated by a couple hundred bytes afterwards (and GPG sig verification fails on those packages).
It's always the same packages that get truncated by the same amounts of data. This is 100% reproducible. It doesn't matter whether I compile the kernel with gcc 2.95.3 or 3.1.1. If I perform the operation on my non-XFS filesystem the problem doesn't happen. If I run 2.6.0-test4-bk2 instead of test4-mm1 on the NFS server, the problem goes away. (I have never run any previous -mm kernels on this server.)
Hmmm... If I sign the packages on the NFS server itself, even with test4-mm1 on the XFS partition, I can't reproduce the problem. *However*, that's a different version of RPM (4.0.4).
Is this enough information to help find the cause of the bug? If not, it might be several days (if I'm unlucky, maybe even a week or two) before I have time to do anything more...
