2007-10-10[PKT_SCHED]: Add stateless NATHerbert Xu
Stateless NAT is useful in controlled environments where restrictions are placed on through traffic such that we don't need connection tracking to correctly NAT protocol-specific data. In particular, this is of interest when the number of flows or the number of addresses being NATed is large, or if connection tracking information has to be replicated and where it is not practical to do so. Previously we had stateless NAT functionality which was integrated into the IPv4 routing subsystem. This was a great solution as long as the NAT worked on a subnet to subnet basis such that the number of NAT rules was relatively small. The reason is that for SNAT the routing based system had to perform a linear scan through the rules. If the number of rules is large then major renovations would have take place in the routing subsystem to make this practical. For the time being, the least intrusive way of achieving this is to use the u32 classifier written by Alexey Kuznetsov along with the actions infrastructure implemented by Jamal Hadi Salim. The following patch is an attempt at this problem by creating a new nat action that can be invoked from u32 hash tables which would allow large number of stateless NAT rules that can be used/updated in constant time. The actual NAT code is mostly based on the previous stateless NAT code written by Alexey. In future we might be able to utilise the protocol NAT code from netfilter to improve support for other protocols. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S.

2007-07-15[NET_SCHED]: Kill CONFIG_NET_CLS_POLICEPatrick McHardy
The NET_CLS_ACT option is now a full replacement for NET_CLS_POLICE, remove the old code. The config option will be kept around to select the equivalent NET_CLS_ACT options for a short time to allow easier upgrades. Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S. Miller <davem@davemloft.net>
2007-07-10[NET_SCHED]: Remove CONFIG_NET_ESTIMATOR optionPatrick McHardy
The generic estimator is always built in anways and all the config options does is prevent including a minimal amount of code for setting it up. Additionally the option is already automatically selected for most cases. Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S. Miller <davem@davemloft.net>
2007-07-10[SCHED]: Qdisc changes and sch_rr added for multiqueuePeter P Waskiewicz Jr
Add the new sch_rr qdisc for multiqueue network device support. Allow sch_prio and sch_rr to be compiled with or without multiqueue hardware support. sch_rr is part of sch_prio, and is referenced from MODULE_ALIAS. This was done since sch_prio and sch_rr only differ in their dequeue routine.

2007-04-25[NET_SCHED]: Use ktime as clocksourcePatrick McHardy
Get rid of the manual clock source selection mess and use ktime. Also use a scalar representation, which allows to clean up pkt_sched.h a bit more and results in less ktime_to_ns() calls in most cases. The PSCHED_US2JIFFIE/PSCHED_JIFFIE2US macros are implemented quite inefficient by this patch, following patches will convert all qdiscs to hrtimers and get rid of them entirely.

2006-12-02[PKT_SCHED]: Make sch_fifo.o available when CONFIG_NET_SCHED is not set.David Kimdon
Based on patch by Patrick McHardy. Add a new option, NET_SCH_FIFO, which provides a simple fifo qdisc without requiring CONFIG_NET_SCHED. The d80211 stack needs a generic fifo qdisc for WME. At present it uses net/d80211/fifo_qdisc.c which is functionally equivalent to sch_fifo.c. This patch will allow the d80211 stack to remove net/d80211/fifo_qdisc.c and use sch_fifo.c instead.

2006-12-02[NET]: Turn nfmark into generic markThomas Graf
nfmark is being used in various subsystems and has become the defacto mark field for all kinds of packets. Therefore it makes sense to rename it to `mark' and remove the dependency on CONFIG_NETFILTER. Signed-off-by: Thomas Graf <tgraf@suug.ch> Signed-off-by: David S. Miller <davem@davemloft.net>

It's better in 2.6.15-rc1-git5, but the menu structure is still a little messed up, the patch below properly indents all menu entries.

2005-11-03[PKT_SCHED]: Rework QoS and/or fair queueing configurationThomas Graf
Make "QoS and/or fair queueing" have its own menu, it's too big to be inlined into "Network options". Remove the obsolete NET_QOS option. Automatically select NET_CLS if needed. Do the same for NET_ESTIMATOR but allow it to be selected manually for statistical purposes. Add comments to separate queueing from classification. Fix dependencies and ordering of classifiers. Improve descriptions/help texts and remove outdated pieces. Signed-off-by: Thomas Graf <tgraf@suug.ch> Signed-off-by: Arnaldo Carvalho de Melo <acme@mandriva.com>

2005-07-11[NET]: move config options out to individual protocolsSam Ravnborg
Move the protocol specific config options out to the specific protocols. With this change net/Kconfig now starts to become readable and serve as a good basis for further re-structuring. The menu structure is left almost intact, except that indention is fixed in most cases. Most visible are the INET changes where several "depends on INET" are replaced with a single ifdef INET / endif pair. Several new files were created to accomplish this change - they are small but serve the purpose that config options are now distributed out where they belongs.

2005-04-16Linux-2.6.12-rc2Linus Torvalds
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
