[TCP]: Set default congestion control when no sysctl.

2006-11-01T23:42:34+00:00

The setting of the default congestion control was buried in
the sysctl code so it would not be done properly if SYSCTL was
not enabled.

[TCP]: default congestion control menu

2006-09-25T03:11:58+00:00

Change how default TCP congestion control is chosen. Don't just use
last installed module, instead allow selection during configuration,
and make sure and use the default regardless of load order.

[NetLabel]: CIPSOv4 engine

2006-09-22T21:53:33+00:00

Add support for the Commercial IP Security Option (CIPSO) to the IPv4
network stack.  CIPSO has become a de-facto standard for
trusted/labeled networking amongst existing Trusted Operating Systems
such as Trusted Solaris, HP-UX CMW, etc.  This implementation is
designed to be used with the NetLabel subsystem to provide explicit
packet labeling to LSM developers.

The CIPSO/IPv4 packet labeling works by the LSM calling a NetLabel API
function which attaches a CIPSO label (IPv4 option) to a given socket;
this in turn attaches the CIPSO label to every packet leaving the
socket without any extra processing on the outbound side.  On the
inbound side the individual packet's sk_buff is examined through a
call to a NetLabel API function to determine if a CIPSO/IPv4 label is
present and if so the security attributes of the CIPSO label are
returned to the caller of the NetLabel API function.

[TCP]: Add tcp_slow_start_after_idle sysctl.

2006-06-18T04:30:53+00:00

A lot of people have asked for a way to disable tcp_cwnd_restart(),
and it seems reasonable to add a sysctl to do that.

[NET]: net.ipv4.ip_autoconfig sysctl removal

2006-06-18T04:30:30+00:00

The sysctl net.ipv4.ip_autoconfig is a legacy value that is not used.

[TCP]: sysctl to allow TCP window > 32767 sans wscale

2006-03-21T06:40:29+00:00

Back in the dark ages, we had to be conservative and only allow 15-bit
window fields if the window scale option was not negotiated.  Some
ancient stacks used a signed 16-bit quantity for the window field of
the TCP header and would get confused.

Those days are long gone, so we can use the full 16-bits by default
now.

There is a sysctl added so that we can still interact with such old
stacks

[INET_SOCK]: Move struct inet_sock & helper functions to net/inet_sock.h

2006-01-03T21:11:21+00:00

To help in reducing the number of include dependencies, several files were
touched as they were getting needed headers indirectly for stuff they use.

Thanks also to Alan Menegotto for pointing out that net/dccp/proto.c had
linux/dccp.h include twice.
