Bug#372855: cupsys: Sending BrowseRelay packets causes EINVAL in sendto()
Package: cupsys
Version: 1.2.1-2
Severity: normal
Relaying CUPS browse packet does not seem to work. Using
BrowseRelay ano2.mech.kth.se anobhs-bcast.mech.kth.se
cases the follwing error message
E [11/Jun/2006:07:14:19 +0200] cupsdUpdateCUPSBrowse: sendto failed for
relay 1
- Invalid argument.
each time a browse packet is received from ano2.mech.kth.se, and these
packets are not relayed. There seems to
be an upstream bug report about this: <http://www.cups.org/str.php?L1745>
but if I understand correctly, that bug report was closed without any
action, since the bug reporter's disk had just crashed, and he could thus
no longer reproduce the problem. The source code looks like
if (sendto(BrowseSocket, packet, bytes, 0,
(struct sockaddr *)&(Relays[i].to),
sizeof(http_addr_t)) <= 0)
at line 1460 in scheduler/dirsvc.c. If I change
sizeof(http_addr_t)
(which evaluates to 256) into
sizeof(struct sockaddr_in)
(which evaluates to 16)
the error message disappears and relaying functionality is restored.
