We have not been bumping this since we create openreqs in TCP,
ie. some 6 years ago. :-)

assumes that it cannot be reached in the crossed SYN case.
This is wrong if the original SYNs came from a malicious packet
generator third party.  This can result in a 4 minute ACK
fight if the sequence numbers are correct.

The fix is the verify the ACK before we do anything else, which
should cover all cases.

This bug was discovered by Casper Dik.

use the most uptodate value of ip_default_ttl sysctl.

in UDP case.  I note in passing that the TCP case is
wrong because TCP does not use sock_writeable()s

during connect when the connection will still have a unique
identity.  Fixes port space exhaustion, especially in web
caches.

Initial work done by Andi Kleen.

It is used to differentiate the devices by the medium
they are attached to.  It is used to change proxy_arp behavior:
the proxy arp feature is enabled for packets forwarded between
two devices attached to different media.

being dumped.

- Fix open_request lookup bug that was already fixed in ipv4

- Answer to neighbour solicitations on SIT, otherwise
  freebsd does not want to talk to us.
- Fix wrong structure nd_msg and... use it :-)

- stop external DoS attack feeding lots of IPv6 prefixes

- respect multicast interface when connecting

1) Two bugs noticed by Pasi:
   - Wrong rtt update interval
   - Forgot to clear retrans_stamp when entering established
     state
2) Missing LAST_ACK case of processing segment text (step 7) in
   tcp_rcv_state_process.
3) Remove "final cut" code, purism is good not all the times. :-)

complete memory corruption.

- no need to check for pskb_may_pull() in ip_local_deliver_finish, header
is guaranteed to be at right place here.
- remove cleaing ip_summed with IP options, it was required due to
broken eth_copy_and_csum, but we do not use it any more
and it happens to break loopback

- do not make path mtu discovery, when it is disabled :-)

pskb_pull really may reallocate packet after the check
for 8 bytes was removed from ip_input, so set icmp
header pointer after pskb_pull call not before.

- fix device leakage in multipath
- fix oops due to race by adding spinlock

In __pskb_pull_tail, pskb_expand_head return value test
was inverted.

large time intervals.

from IPv4 sysctl documentation.

Add destroy callback to ip_conntrack_helper, to be used by L4
protocol trackers.

This patch remove unused variable/function/define, and small indent
cleanup.

The following patch moves MSDOS_SB() and MSDOS_I() into #define
__KERNEL__.

- Apply more patches from Vojtech Pavlik for the handling of host chip setup.
   Hopefully they are settled now.

- Kill unused CONFIG_BLK_DEV_MODES

- Push register addressing down in to task_vlb_sync.

- Make the taskfile parsing stuff actually readable. This is compressing the
   code by an incredible amount. We use just one function doing the whole
   scanning right now. This should make sure that the IRQ handler used by a
   particular command is always right.  I didn't introduce typos hopefully
   here.

- Don't call ide_handler_parser as argument for do_taskfile() any longer. We
   have killed this function by coalescing it's functionality with
   ide_cmd_type_parser() anyway.

- Kill unused SLC90E66 code, which Vojtech apparently missed in his patch.

- sync up with 2.5.7-pre2

Once again the actual patch is rather big mostly due to the removal of
some default configuration variables which are not used anylonger. So time for
the next patch stage.

- add joystick support for CS46xx driver
- Audigy code updates
- fix sound/core/Config.in (wrong dep_tristate usage)
- rawmidi interface fixes (memory leak)
- chang spinlock to rwlock in pcm_native.c (streams linking)
- further fixes of dependencies in Makefiles
- remove experimental time-sync support from sequencer
- fix/update for 32-bit -> 64-bit ioctl converter code
- wavefront driver cleanups
- CMIPCI driver updates
- update joystick support in CS4281
- add detection (not support) of M Audio Delta1010LT
- add AMD768 PCI ID to intel8x0 driver
- add joystick code to trident driver
- remove static variable initialization to zero

This adds initial driverfs support to ISAPNP driver.  It was approved by
the ISAPNP maintainer (Jaroslav Kysela).
