Ok, this patch looks ok, if it's confirmed to unbreak apache.
Yes, sounds reasonable. But I don't think that, as Peter suggested in
another mail, that glibc should automatically wrap the syscall to
provide support for larger sizes. The caller probably should know when
a transfer was cut short.
Agreed; that's exactly what a short return in supposed to do. Since a
short return is compatible with the defined API, that's not a problem.
However, this patch only addresses sendfile(), and this is apparently a
much more pervasive problem. We need something similar for all the I/O
system calls that are affected by this particular issue.
