Regression in UDP

[Jakub Jermář]

Some changes in changeset:mainline,349 introduced a regression into the UDP module.

In changeset:mainline,348, the UDP will function normally, as evidenced e.g. by the netecho utility. In changeset:mainline,349, however, UDP will crash with the following stack trace:

packet_get_id+0xc
udp_sendto_message+0x35
udp_process_client_messages+0x2b1
udp_message+0x4d
tl_client_connection+0x61
…

To reproduce, start HelenOS like this:

$ contrib/conf/ne-qe.sh

and from withing HelenOS, do:

# netstart
# netecho -v -p 8080

then, from outside of HelenOS, do:

$ echo -n "GET / HTTP/1.0\r\n\r\n" | nc -u localhost 8080
$ echo -n "GET / HTTP/1.0\r\n\r\n" | nc -u localhost 8080

Ok, this was quick.

Fixed in changeset:mainline,636.
