11 years agoImplement a number of major new features to PF.
Matthew Dillon [Fri, 11 Apr 2008 18:21:49 +0000 (18:21 +0000)]
Implement a number of major new features to PF.

* Implement several new options to keep/modulate/synproxy state.
  'pickups', 'no-pickups', and 'hash-only'.  Example:

    pass on $ext_if inet from any to any keep state (pickups)

* Implement a SET directive to set the default keep policy.  Example:

    set keep-policy keep state (pickups)
    pass on $ext_if inet from any to any

* Implement the 'no state' phrase for rules, disabling any previously
  specified default state policy for that rule (ala OpenBSD).

'pickups' and 'hash-only' imply no flag restrictions, no-pickups implies
flags S/SA.  When pickups are enabled the state code will re-establish state
for existing TCP connections.  Because the tcp options passed in the SYNs
are not known when this occurs, sequence space checking will be disabled
for those connections.  The 'hash-only' mode allows pickups but disables
sequence space checking regardless of whether the SYN packets were observed
or not.

The state code no longer attempts to do sequence space checking if it has
no information on TCP options passed in SYN packets.  The SYN from both
ends must be observed for sequence space checking to occur (which is what
happens by default due to flag restrictions).

It should be noted that OpenBSD defaults to 'keep state' with the equivalent
of no-pickups.  The problem with this is that rebooting you router or
otherwise losing state will cause existing TCP connections to be reset,
and I do not think this is an appropriate default for PF.  DragonFly does
not default to using keep state but introduces the global SET directive
to allow it to be enabled by default.

Finally, note that when using pickups or hash-only, if you desire PF to
not drop TCP connections on loss of state you need to have a few more
rules then usual to pickup on packets going the opposite direction.
For example, if you allow outgoing connections then you ALSO have to keep
state on INCOMING packets with 'flags /S' (i.e. 'established') in order
to ensure that active connections can be re-established on loss of state
by packets in either direction.

This isn't too bad since anyone using queueing has to use multiple rule
sets anyway to ensure that state is established on the proper queue.

In anycase, DragonFly now allows you to pick your poison.  One global SET
directive and you can use OpenBSD's policy, or you can make your own.

buckets to jump the round robin.  This fairq algorithm is currently unweighted
but traffic can still be classified with the global priority model.  For
each queue traffic is normally round robined by taking a packet from each
bucket in turn.

  the need to explicitly classify it.  Bandwidth is managed on a per-bucket
  basis.

  service classifications. e.g. VOIP, web, mail, PtP, etc.

* Weighted fairq not implemented (beyond using classification into priority
  queues), but the circular bucket design makes it a fairly easy task if

It's frankly long past time that we turn net.inet.tcp.always_keepalive
on by default.

The default test internal is 2 hours of idle (left unchanged).  I am not
going to make it shorter but I will note that while you might not have wanted
to have the feature enabled 15 years ago (because many people were using
demand-dial), these days you actually almost universally want the feature
enabled for a multitude of reasons:

(1) Because you will often be running over a NAT and can lose the NAT
    entry if the connection stays idle with no traffic at all for too
    long a period of time.

(2) Because you will often be running over stateful filters which can also
    get confused and lose the table entry if they see no traffic for too
    long a period of time.

(3) Because having this turned on guarantees that stuck tcp connections,
    especially those generated through batch operations, will eventually
    get unstuck.  A TCP connection can become stuck if it is waiting on
    data and the remote end has closed the connection, but the RST got lost.
    Without this feature such connections can remain stuck literally
    forever.

In some cases you might even need a far shorter interval but that is another
issue not addressed by this commit.

Sepherosa Ziehau [Wed, 26 Mar 2008 14:44:59 +0000 (14:44 +0000)]
Fix bugs concerning cached route entry in UDP inpcb.

For an unconnected and unbound UDP socket, first sending calls in_pcbladdr()
to fix the local port, which may change the target CPU of the next sending.
in_pcbladdr() has a side effect to allocate the route entry cached in inpcb.
If the target CPU after in_pcbladdr() is no longer the current CPU, then
the route entry will be accessed/freed on non-owner CPU during later sending.
Similarly, connect/disconnect a UDP socket may change the target CPU too; the
target CPU may no longer the owner of the cached route entry.

So, for the first sending happens on an unconnected and unbound UDP socket,
the target CPU of next sending is compared with the current CPU.  If they
are different, then cached route entry will be freed, so next time a packet
sent on this socket, a new route entry owned by the correct CPU will be
cached.  Same target CPU check is applied to UDP socket connect/disconnect.

Originally UDP PRU_CONNECT always happens on CPU0, which will cause problem if
following conditions are met:
- Dst of the cached route entry is different from the dst to be connected
- Cached route entry is not allocated on CPU0
This could happen if two datagram are sent on an unbounded and unconnected UDP
socket, then later connectting this UDP socket will cause cached route entry
being freed on different CPU.  To solve this problem, PRU_CONNECT is dispatched
according to existing [lf]{addr,port} pairs.

If in_pcbladdr() fails after altering the cached route entry, the cached route
entry is freed to make sure that freeing this cached route entry happens on
its owner CPU.
