4f9bc6c6b7 Don't try to compile in INET6 support when NOINET6 is defined. 2000-04-15 20:45:52 +00:00

b5e819ec23 Apply TCP_EXPIRE_CONNECTED (86400 seconds) timeout only to established 
connections, after SYN packets were seen from both ends.  Before this,
it would get applied right after the first SYN packet was seen (either
from client or server).  With broken TCP connection attempts, when the
remote end does not respond with SYNACK nor with RST, this resulted in
having a useless (ie, no actual TCP connection associated with it) TCP
link with 86400 seconds TTL, wasting system memory.  With high rate of
such broken connection attempts (for example, remote end simply blocks
these connection attempts with ipfw(8) without sending RST back), this
could result in a denial-of-service.

f167e54283 Make partially specified permanent links without `dst_addr' 
but with `dst_port' work for outgoing packets.

This case was not handled properly when I first fixed this
in revision 1.17.

This change is also required for the upcoming improved PPTP
support patches -- that is how I found the problem.

Before this change:

# natd -v -a aliasIP \
  -redirect_port tcp localIP:localPORT publicIP:publicPORT 0:remotePORT

Out [TCP]  [TCP] localIP:localPORT -> remoteIP:remotePORT aliased to
           [TCP] aliasIP:localPORT -> remoteIP:remotePORT

After this change:

# natd -v -a aliasIP \
  -redirect_port tcp localIP:localPORT publicIP:publicPORT 0:remotePORT

Out [TCP]  [TCP] localIP:localPORT -> remoteIP:remotePORT aliased to
           [TCP] publicIP:publicPORT -> remoteIP:remotePORT

1d013a86ed Fix pthread_suspend_np/pthread_resume_np. For the record, suspending a 
thread waiting on an event (I/O, condvar, etc) will, when resumed using
pthread_resume_np, return with EINTR.  For example, suspending and resuming
a thread blocked on read() will not requeue the thread for the read, but
will return -1 with errno = EINTR.  If the suspended thread is in a critical
region, the thread is suspended as soon as it leaves the critical region.

Fix a bogon in pthread_kill() where a signal was being delivered twice
to threads waiting in sigwait().
