Hi,

I have bisected a strange regression down to this commit that you made. If I
apply the attached patch (which restores the original 2 lines of code), then
everything works correctly. I apologize, but I don't have a simple
reproducer. The gist of the problem is that Java cannot decrypt a file under
certain circumstances, e.g., "ERROR javax.crypto.BadPaddingException: pad
block corrupted". There is more information in the bug report at
http://bugs.launchpad.net/bugs/588861 , but not all of it is helpful.

Any thoughts?


It seems the target of sendfile(2) isn't a socket, and the current
sendfile(2) code can't handle non-socket target correctly. Please try
this patch: http://marc.info/?l=linux-fsdevel&m=127488508224173&w=2 .


Thanks - this patch appears to have fixed 'pad block corrupted' error. Is it queued for 2.6.35-rc4 ?
