[Bug 491699] [NEW] Trash address family returned by sctp_getpaddrs

Thu Dec 3 02:27:16 UTC 2009

Public bug reported:

Binary package hint: lksctp-tools

Hi,

Running Ubuntu Karmic with 
libsctp1 Version: 1.0.10+dfsg-1
Kernel 2.6.31-15-generic

I have a SCTP connected socket, I call :
count = sctp_getpaddrs(sock, 0, &data)

The return is:
count = 8
data = 2e3231007f00000100000000000000000000000000000000000000000a00dc520000000000000000000000000000000000000001000000000200dc5285f392a500000000000000000000000000000001000000000a00dc5200000000fe80000000000000021d09fffe897d68000000000200dc520a000a01fe80000000000000...

The first address is invalid since it shows an address family of 0x2e32.
It is then impossible to parse the remaining of the buffer since we
don't know the first address size.

This bug did not appear with Ubuntu Intrepid.
