New Revision: 269489
URL: http://svnweb.freebsd.org/changeset/base/269489
Log:
Partial revert of r262867.
r262867 was described as fixing socket buffer checks for SOCK_SEQPACKET,
but also changed one of the SOCK_DGRAM code paths to use the new
sbappendaddr_nospacecheck_locked() function. This lead to SOCK_DGRAM
bypassing socket buffer limits.
