Description Nick Leuta 2004-01-11 22:50:13 UTC 
A bug in the sendfile(2) system call has been fixed in FreeBSD at
1 December 2003. The synopsis of the bug is: the data sent with help of
sendfile(2) would be corrupted due to sendfile(2) being erroneously
automatically restarted after a signal is delivered. The fixed sendfile(2)
system call returns the EINTR error, which was not documented earlier.

BSDftpd-ssl 1.0.0 will send the corrupted data in all FreeBSD versions before
1 December 2003 (include RELENG_4_9 and RELENG_5_1 Security Branches). In
FreeBSD versions after 1 December 2003 the data transfer may be aborted with
the next message, because the EINTR error isn't handled:
"426 Data connection: Interrupted system call".
