13 years ago[DCCP]: Allow to parse options on Request Sockets
Gerrit Renker [Thu, 13 Dec 2007 14:29:24 +0000]
[DCCP]: Allow to parse options on Request Sockets

The option parsing code currently only parses on full sk's. This causes a problem for
options sent during the initial handshake (in particular timestamps and feature-negotiation
options). Therefore, this patch extends the option parsing code with an additional argument
for request_socks: if it is non-NULL, options are parsed on the request socket, otherwise
the normal path (parsing on the sk) is used.

Subsequent patches, which implement feature negotiation during connection setup, make use
of this facility.

Gerrit Renker [Thu, 13 Dec 2007 14:25:01 +0000]
[DCCP]: Support for server holding timewait state

This adds a socket option and signalling support for the case where the server
holds timewait state on closing the connection, as described in RFC 4340, 8.3.

Since holding timewait state at the server is the non-usual case, it is enabled
via a socket option. Documentation for this socket option has been added.

The setsockopt statement has been made resilient against different possible cases
of expressing boolean `true' values using a suggestion by Ian McDonald.

13 years ago[DCCP]: Use maximum-RTO backoff from DCCP spec
Gerrit Renker [Thu, 13 Dec 2007 14:16:23 +0000]
[DCCP]: Use maximum-RTO backoff from DCCP spec

This removes another Fixme, using the TCP maximum RTO rather than the value
specified by the DCCP specification. Across the sections in RFC 4340, 64
seconds is consistently suggested as maximum RTO backoff value; and this is
the value which is now used.

I have checked both termination cases for retransmissions of Close/CloseReq:
with the default value 15 of `retries2', and an initial icsk_retransmit = 0,
it takes about 614 seconds to declare a non-responding peer as dead, after
which the final terminating Reset is sent. With the TCP maximum RTO value of
120 seconds it takes (as might be expected) almost twice as long, about 23
minutes.

Gerrit Renker [Thu, 13 Dec 2007 14:02:43 +0000]
[DCCP]: Shift the retransmit timer for active-close into output.c

When performing active close, RFC 4340, 8.3. requires to retransmit the
Close/CloseReq with a backoff-retransmit timer starting at intially 2 RTTs.

This patch shifts the existing code for active-close retransmit timer
into output.c, so that the retransmit timer is started when the first
Close/CloseReq is sent. Previously, the timer was started when, after
releasing the socket in dccp_close(), the actively-closing side had not yet
reached the CLOSED/TIMEWAIT state.

The patch further reduces the initial timeout from 3 seconds to the required
2 RTTs, where - in absence of a known RTT - the fallback value specified in
RFC 4340, 3.4 is used.

13 years ago[DCCP]: Perform SHUT_RD and SHUT_WR on receiving close
Gerrit Renker [Thu, 13 Dec 2007 13:28:43 +0000]
[DCCP]: Perform SHUT_RD and SHUT_WR on receiving close

This patch performs two changes:

1) Close the write-end in addition to the read-end when a fin-like segment
  (Close or CloseReq) is received by DCCP. This accounts for the fact that DCCP,
  in contrast to TCP, does not have a half-close. RFC 4340 says in this respect
  that when a fin-like segment has been sent there is no guarantee at all that
  any   further data will be processed.
  Thus this patch performs SHUT_WR in addition to the SHUT_RD when a fin-like
  segment is encountered.

2) Minor change: I noted that code appears twice in different places and think it
   makes sense to put this into a self-contained function (dccp_enqueue()).

To reproduce:

# create a tunnel:

# try to change the bounding device from eth0 to eth1:

13 years ago[CCID3]: Interface CCID3 code with newer Loss Intervals Database
Gerrit Renker [Wed, 12 Dec 2007 16:06:14 +0000]
[CCID3]: Interface CCID3 code with newer Loss Intervals Database

This hooks up the TFRC Loss Interval database with CCID 3 packet reception.
In addition, it makes the CCID-specific computation of the first loss
interval (which requires access to all the guts of CCID3) local to ccid3.c.

The patch also fixes an omission in the DCCP code, that of a default /
fallback RTT value (defined in section 3.4 of RFC 4340 as 0.2 sec); while
at it, the  upper bound of 4 seconds for an RTT sample has  been reduced to
match the initial TCP RTO value of 3 seconds from[RFC 1122, 4.2.3.1].

Gerrit Renker [Wed, 12 Dec 2007 15:50:51 +0000]
[TFRC]: Ringbuffer to track loss interval history

A ringbuffer-based implementation of loss interval history is easier to
maintain, allocate, and update.

The `swap' routine to keep the RX history sorted is due to and was written
by Arnaldo Carvalho de Melo, simplifying an earlier macro-based variant.

Details:
 * access to the Loss Interval Records via macro wrappers (with safety checks);
 * simplified, on-demand allocation of entries (no extra memory consumption on
   lossless links); cache allocation is local to the module / exported as service;
 * provision of RFC-compliant algorithm to re-compute average loss interval;
 * provision of comprehensive, new loss detection algorithm
  - support for all cases of loss, including re-ordered/duplicate packets;
  - waiting for NDUPACK=3 packets to fill the hole;
- updating loss records when a late-arriving packet fills a hole.

Recently David Miller and Herbert Xu pointed out that struct net becomes
overbloated and un-maintainable. There are two solutions:
- provide a pointer to a network subsystem definition from struct net.
  This costs an additional dereferrence
- place sub-system definition into the structure itself. This will speedup
  run-time access at the cost of recompilation time

The second approach looks better for us. Other sub-systems will follow.

[IPV6] route6/fib6: Don't panic a kmem_cache_create.

If the kmem_cache_creation fails, the kernel will panic. It is
acceptable if the system is booting, but if the ipv6 protocol is
compiled as a module and it is loaded after the system has booted, do
we want to panic instead of just failing to initialize the protocol ?

The init function is now returning an error and this one is checked
for protocol initialization. So the ipv6 protocol will safely fails.

[TFRC]: New rx history code

Credit here goes to Gerrit Renker, that provided the initial implementation for
this new codebase.

I modified it just to try to make it closer to the existing API, renaming some
functions, add namespacing and fix one bug where the tfrc_rx_hist_alloc was not
freeing the allocated ring entries on the error path.

Original changeset comment from Gerrit:
      -----------
This provides a new, self-contained and generic RX history service for TFRC
based protocols.

Details:
 * new data structure, initialisation and cleanup routines;
 * allocation of dccp_rx_hist entries local to packet_history.c,
   as a service exported by the dccp_tfrc_lib module.
 * interface to automatically track highest-received seqno;
 * receiver-based RTT estimation (needed for instance by RFC 3448, 6.3.1);
 * a generic function to test for `data packets' as per  RFC 4340, sec. 7.7.
