* [NET]: use __read_mostly on kmem_cache_t , DEFINE_SNMP_STAT pointersEric Dumazet2005-08-301-1/+1
| | | | | | | | | | | | | This patch puts mostly read only data in the right section (read_mostly), to help sharing of these data between CPUS without memory ping pongs. On one of my production machine, tcp_statistics was sitting in a heavily modified cache line, so *every* SNMP update had to force a reload.

* [NETLINK]: Add properly module refcounting for kernel netlink sockets.Harald Welte2005-08-301-1/+1
| | | | | | | | | | | - Remove bogus code for compiling netlink as module - Add module refcounting support for modules implementing a netlink protocol - Add support for autoloading modules that implement a netlink protocol as soon as someone opens a socket for that protocol Signed-off-by: Harald Welte <laforge@netfilter.org> Signed-off-by: David S.

* [NETFILTER]: reduce netfilter sk_buff enlargementHarald Welte2005-08-301-3/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | As discussed at netconf'05, we're trying to save every bit in sk_buff. The patch below makes sk_buff 8 bytes smaller. I did some basic testing on my notebook and it seems to work. The only real in-tree user of nfcache was IPVS, who only needs a single bit. Unfortunately I couldn't find some other free bit in sk_buff to stuff that bit into, so I introduced a separate field for them. Maybe the IPVS guys can resolve that to further save space. Initially I wanted to shrink pkt_type to three bits (PACKET_HOST and alike are only 6 values defined), but unfortunately the bluetooth code overloads pkt_type :( The conntrack-event-api (out-of-tree) uses nfcache, but Rusty just came up with a way how to do it without any skb fields, so it's safe to remove it. - remove all never-implemented 'nfcache' code - don't have ipvs code abuse 'nfcache' field. currently get's their own compile-conditional skb->ipvs_property field. IPVS maintainers can decide to move this bit elswhere, but nfcache needs to die. - remove skb->nfcache field to save 4 bytes - move skb->nfctinfo into three unused bits to save further 4 bytes Signed-off-by: Harald Welte <laforge@netfilter.org> Signed-off-by: David S.

* [NET]: move config options out to individual protocolsSam Ravnborg2005-07-121-0/+31
| | | | | | | | | | | | | | | | | 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.

* [NETFILTER]: Fix connection tracking bug in 2.6.12Patrick McHardy2005-06-291-1/+1
| | | | | | | | | | | | | | | In 2.6.12 we started dropping the conntrack reference when a packet leaves the IP layer. This broke connection tracking on a bridge, because bridge-netfilter defers calling some NF_IP_* hooks to the bridge layer for locally generated packets going out a bridge, where the conntrack reference is no longer available. This patch keeps the reference in this case as a temporary solution, long term we will remove the defered hook calling. No attempt is made to drop the reference in the bridge-code when it is no longer needed, tc actions could already have sent the packet anywhere.

* [BRIDGE]: receive path optimizationStephen Hemminger2005-05-291-1/+1
| | | | | | | | | | | | This improves the bridge local receive path by avoiding going through another softirq. The bridge receive path is already being called from a netif_receive_skb() there is no point in going through another receiveq round trip. Recursion is limited because bridge can never be a port of a bridge so handle_bridge() always returns. Signed-off-by: David S. Miller <davem@davemloft.net>
* [BRIDGE]: prevent bad forwarding table updatesStephen Hemminger2005-05-292-2/+7

* Linux-2.6.12-rc2v2.6.12-rc2Linus Torvalds2005-04-1740-0/+8982
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!
