19 years agoThe TCP stack is notified every time userland reads from the TCP socket
Matthew Dillon [Tue, 3 Aug 2004 00:25:54 +0000 (00:25 +0000)]
The TCP stack is notified every time userland reads from the TCP socket
buffer, because a pure-window-update ACK might be required.  The previous
code would send a pure window update once the difference between the last
advertised window and the current window exceeded 2 segments and also when it
exceeded 1/2 the high water mark.

On GigE networks this can cause a pure window update to occur once every
8 packets (resulting in 5 acks instead of 4) prior to the TCP t_outputq
commit and once every 8 packets (resulting in 2 acks instead of 1) after
the TCP t_outputq commit.  So on a GigE network servicing a high performance
TCP stream, the result is double the number of acks that are actually
necessary.

Conditionalize the 2 segment test with a sysctl.  The sysctl is
net.inet.tcp.avoid_pure_win_update and is set to 1 by default, meaning
that the 2 segment ack does NOT occur (i.e. we should get higher
performance).  It may be turned off to revert to the prior two-ack
algorithm.

This code is considered experimental but since it involves only a pure
window update and we still have the catch-all case this commit is enabling
the new algorithm.  Further tuning might be required, possibly reducing the
1/2 hiwat test to 1/3 or 1/4 hiwat.

Ideally we want to avoid pure window update acks entirely in the normal
streaming case, which means we want to have a TCP buffer that is large
enough to pipeline the networked stream AND the process consuming the data.
On a GigE network this typically equates to the packet batching that occurs
per interrupt.  This batching is typically 8 1448 byte segments == ~11K,
plus turn around overhead and the 1/2 hiwat test so we want an incoming
socket buffer of at least ~11K * 2 + slop which should come to around ~32K
in order to avoid sending (unnecessary) pure window updates on a high
performance TCP stream.

19 years agotcp_input()'s DELAY_ACK() code checks to see if the delayed ack timer is
Matthew Dillon [Tue, 3 Aug 2004 00:04:13 +0000 (00:04 +0000)]
tcp_input()'s DELAY_ACK() code checks to see if the delayed ack timer is
running and if it is not it starts it and returns rather then issue an
ack.  If the timer is already running tcp_input() will generate an immediate
ack, resulting in one ack every other packet.  This every-other-packet ack
is usually required to ensure that the window does not close too much and
stall the sender, but it really only exists because the tcp stack does not
look ahead to see if there are other incoming packets that need to be
processed that might themselves require additional acks.  For optimal
operation we really want to process all the pending TCP packets for
the connection before sending any 'normal' acks.

Many ethernet interfaces, including and most especially GigE interfaces,
rate-limit their interrupts.  This results in several packets being moved
from the RX ring to the TCP/IP stack all at once, in a batch.

GIVE THE TCP stack its own netisr dispatcher loop rather then using the
generic netisr dispatcher loop.  The TCP dispatcher loop will call an
additional routine, tcp_willblock(), after all messages queued to the TCP
protocol stack have been exhausted.

When tcp_input() needs to send an ack in the normal header-prediction case
it now places the TCPCB on a queue rather then send an immediate ack.
tcp_willblock() processes this queue and calls tcp_output() to send the
actual ack.

The result is that on a GigE interface which typically queues 8+ packets
per interrupt, a TCP stream will only be acked once per ~8 packets rather
then 4 times (every other packet) per ~8 packets.  This *GREATLY* reduces TCP
protocol overhead and network ack traffic on both ends of the connection.

NOTE: a later commit will deal with pure window space updates which generate
an additional ACK per ~8 packets when the user program drains the buffer.

Matthew Dillon [Wed, 28 Jul 2004 20:40:35 +0000 (20:40 +0000)]
(From Alan):
 Correct a very old error in both vm_object_madvise() (originating in
 vm/vm_object.c revision 1.88) and vm_object_sync() (originating in
 vm/vm_map.c revision 1.36): When descending a chain of backing objects,
 both use the wrong object's backing offset.  Consequently, both may
 operate on the wrong pages.

(From Matt):
 In DragonFly the code needing correction is in vm_object_madvise() and
 vm_map_clean() (that code in vm_map_clean() was moved to vm_object_sync()
 in FreebSD-5 hence the FreeBSD-5 correction made by Alan was slight
 different).

 The madvise case could produce corrupted user memory when MADV_FREE was
 used, primarily on server-forked processes (where shadow objects exist)
 PLUS a special set of additional circumstances:  (1) The deeper shadow
 layers had to no longer be shared, (2) Either the memory had been swapped
 out in deeper shadow layers (not just the first shadow layer), resulting
 in the wrong swap space being freed, or (2) the forked memory had not yet
 been COW'd (and the deeper shadow layer is no longer shared) AND also had
 not yet been collapsed backed into the parent (e.g.  the original parent
 and/or other forks had exited and/or the memory had been isolated from
 them already).

 This bug could be responsible for all of the sporatic madvise oddness
 that has been reported over the years, especially in earlier days when
 systems had less memory and paged to swap a lot more then they do today.
 These weird failure cases have led people to generally not use MADV_FREE
 (in particular the 'H' malloc.conf option) as much as they could.  Also
 note that I tightened up the VM object collapse code considerably in
 FreeBSD-4.x making the failure cases above even less likely to occur.

 The vm_map_clean() (vm_object_sync() in FreeBSD-5) case is not likely
 to produce failures and it might not even be possible for it to occur
 in the first place since it requires PROT_WRITE mapped vnodes to exist
 in a backing object, which either might not be possible or might only occur
 under extrodinary circumstances.  Plus the worst that happens is that the
 vnode's data doesn't get written out immediately (but always will later on).

 Kudos to Alan for finding this old bug!

Remove UIO_USERISPACE, we do not support any split instruction/data
address space machines such as the PDP-11.  It is not used anywhere
in the kernel.

Remove it from the manual page as well; the only place where it is
referenced now is the old 4.4BSD FS Interface doc which cannott be
changed.

Mostly obtained from FreeBSD -HEAD.
