* [TCP]: TCP Low Priority congestion controlWong Hoi Sing Edison2006-06-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | TCP Low Priority is a distributed algorithm whose goal is to utilize only the excess network bandwidth as compared to the ``fair share`` of bandwidth as targeted by TCP. Available from: http://www.ece.rice.edu/~akuzma/Doc/akuzma/TCP-LP.pdf Original Author: Aleksandar Kuzmanovic <akuzma@northwestern.edu> See http://www-ece.rice.edu/networks/TCP-LP/ for their implementation. As of 2.6.13, Linux supports pluggable congestion control algorithms. Due to the limitation of the API, we take the following changes from the original TCP-LP implementation: o We use newReno in most core CA handling. Only add some checking within cong_avoid. o Error correcting in remote HZ, therefore remote HZ will be keeped on checking and updating. o Handling calculation of One-Way-Delay (OWD) within rtt_sample, sicne OWD have a similar meaning as RTT. Also correct the buggy formular. o Handle reaction for Early Congestion Indication (ECI) within pkts_acked, as mentioned within pseudo code. o OWD is handled in relative format, where local time stamp will in tcp_time_stamp format.

* [NETFILTER]: H.323 helper: replace internal_net_addr parameter by ↵Patrick McHardy2006-06-18
| | | | | | | | | | | | | | | | routing-based heuristic Call Forwarding doesn't need to create an expectation if both peers can reach each other without our help. The internal_net_addr parameter lets the user explicitly specify a single network where this is true, but is not very flexible and even fails in the common case that calls will both be forwarded to outside parties and inside parties. Use an optional heuristic based on routing instead, the assumption is that if bpth the outgoing device and the gateway are equal, both peers can reach each other directly.

* [NETFILTER]: amanda helper: convert to textsearch infrastructurePatrick McHardy2006-06-18
| | | | | | | | | | | | | When a port number within a packet is replaced by a differently sized number only the packet is resized, but not the copy of the data. Following port numbers are rewritten based on their offsets within the copy, leading to packet corruption. Convert the amanda helper to the textsearch infrastructure to avoid the copy entirely.

* [IPSEC] xfrm: Use IPPROTO_MAX instead of 256Herbert Xu2006-06-18
| | | | | | | | The size of the type_map array (256) comes from the number of IP protocols, i.e., IPPROTO_MAX. This patch is based on a suggestion from Ingo Oeser. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S. Miller <davem@davemloft.net>
* [IPSEC] proto: Move transport mode input path into xfrm_mode_transportHerbert Xu2006-06-18
| | | | | | | | | | | | | | | | | Now that we have xfrm_mode objects we can move the transport mode specific input decapsulation code into xfrm_mode_transport. This removes duplicate code as well as unnecessary header movement in case of tunnel mode SAs since we will discard the original IP header immediately. This also fixes a minor bug for transport-mode ESP where the IP payload length is set to the correct value minus the header length (with extension headers for IPv6). Of course the other neat thing is that we no longer have to allocate temporary buffers to hold the IP headers for ESP and IPComp.

* [IPSEC] xfrm: Abstract out encapsulation modesHerbert Xu2006-06-18
| | | | | | | | | | | | | | This patch adds the structure xfrm_mode. It is meant to represent the operations carried out by transport/tunnel modes. By doing this we allow additional encapsulation modes to be added without clogging up the xfrm_input/xfrm_output paths. Candidate modes include 4-to-6 tunnel mode, 6-to-4 tunnel mode, and BEET modes.

* [IPSEC] xfrm: Undo afinfo lock proliferationHerbert Xu2006-06-18
| | | | | | | | | | | | | | | | | | | The number of locks used to manage afinfo structures can easily be reduced down to one each for policy and state respectively. This is based on the observation that the write locks are only held by module insertion/removal which are very rare events so there is no need to further differentiate between the insertion of modules like ipv6 versus esp6. The removal of the read locks in xfrm4_policy.c/xfrm6_policy.c might look suspicious at first. However, after you realise that nobody ever takes the corresponding write lock you'll feel better :) As far as I can gather it's an attempt to guard against the removal of the corresponding modules. Since neither module can be unloaded at all we can leave it to whoever fixes up IPv6 unloading :) Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S.

* [TG3]: Add recovery logic when MMIOs are re-orderedMichael Chan2006-06-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add recovery logic when we suspect that the system is re-ordering MMIOs. Re-ordered MMIOs to the send mailbox can cause bogus tx completions and hit BUG_ON() in the tx completion path. tg3 already has logic to handle re-ordered MMIOs by flushing the MMIOs that must be strictly ordered (such as the send mailbox). Determining when to enable the flush is currently a manual process of adding known chipsets to a list. The new code replaces the BUG_ON() in the tx completion path with the call to tg3_tx_recover(). It will set the TG3_FLAG_MBOX_WRITE_REORDER flag and reset the chip later in the workqueue to recover and start flushing MMIOs to the mailbox. A message to report the problem will be printed. We will then decide whether or not to add the host bridge to the list of chipsets that do re-ordering. We may add some additional code later to print the host bridge's ID so that the user can report it more easily. The assumption that re-ordering can only happen on x86 systems is also removed.

* [LLC]: allow applications to get copy of kernel datagramsStephen Hemminger2006-06-18
