b09a1d85ff Remove impossible (hk_peer == NULL) check from ng_address_hook().
Valid hook can't have NULL peer. Even invalid one can't, as it is resets to
deadhook, but not NULL.

c3b3361aa8 Add session ID hashing to speedup incoming packets dispatch in case
of many connections working via the same tunnel. For example, in case
of full "client <-> LAC <-> LNS" setup.

dd8463bf88 Improve apply callback error reporting:
Before this patch callback returned result of the last finished call chain.
Now it returns last nonzero result from all call chain results in this request.

As soon as this improvement gives reliable error reporting, it is now possible
to remove dirty workaround in ng_socket, made to return ENOBUFS error statuses
of request-response operations. That workaround was responsible for returning
ENOBUFS errors to completely unrelated requests working at the same time
on socket.

786b28be16 To avoid control data losses do not acknowledge recieving of control packet
if netgraph reported error while delivering to destination.
Reset 'next send' counter to the last requested by peer on ack timeout
to resend all subsequest packets after lost one again without additional hints.

cbff2d5782 Send only one incoming notification at a time to reduce queue
trashing and improve performance.
Remove waitflag argument from ng_ksocket_incoming2(), it means nothing
as function call was queued by netgraph.
Remove node validity check, as node validity guarantied by netgraph.
Update comments.

19469bf19f Increase default queue items allocation limit from 512 to 4096 items
to avoid terrible unpredicted effects for netgraph operation of their
exhaustion while allocating control messages.
Add separate configurable 512 items limit for data items allocation
for DoS/overload protection.

34f9d2c8a9 Use rtalloc1() instead of rtalloc_ign(). It returns a locked
rtentry. We quickly copy the fields of interest, and then
RTFREE_LOCKED(). This should be faster then lock & unlock the
rtentry twice.

ce18638805 Remove explicit locking of struct file.
- Introduce a finit() which is used to initailize the fields of struct file
   in such a way that the ops vector is only valid after the data, type,
   and flags are valid.
 - Protect f_flag and f_count with atomic operations.
 - Remove the global list of all files and associated accounting.
 - Rewrite the unp garbage collection such that it no longer requires
   the global list of all files and instead uses a list of all unp sockets.
 - Mark sockets in the accept queue so we don't incorrectly gc them.

bdee30611d Add a new 'why' argument to kdb_enter(), and a set of constants to use
for that argument.  This will allow DDB to detect the broad category of
reason why the debugger has been entered, which it can use for the
purposes of deciding which DDB script to run.

Assign approximate why values to all current consumers of the
kdb_enter() interface.
