SVN rev 222408 on 2011-05-28 08:13:39Z by lstewart
MFC r216758,217252:
- Add some helper hook points to the TCP stack. The hooks allow Khelp modules to
access inbound/outbound events and associated data for established TCP
connections. The hooks only run if at least one hook function is registered
for the hook point, ensuring the impact on the stack is effectively nil when
no TCP Khelp modules are loaded. struct tcp_hhook_data is passed as contextual
data to any registered Khelp module hook functions.
- Add an OSD (Object Specific Data) pointer to struct tcpcb to allow Khelp
modules to associate per-connection data with the TCP control block.
- Tweak the MFCed code to preserve the ABI of the 8-STABLE branch with respect
to "struct tcpcb" by consuming some of the padding within the struct.
- Bump __FreeBSD_version to 802506.
