2005-12-26[BR_NETFILTER]: Fix leak if skb traverses > 1 bridgeDavid Kimdon
Call nf_bridge_put() before allocating a new nf_bridge structure and potentially overwriting the pointer to a previously allocated one. This fixes a memory leak which can occur when the bridge topology allows for an skb to traverse more than one bridge.

2005-12-19[BRIDGE-NF]: Fix bridge-nf ipv6 length checkBart De Schuymer
A typo caused some bridged IPv6 packets to get dropped randomly, as reported by Sebastien Chaumontet. The patch below fixes this (using skb->nh.raw instead of raw) and also makes the jumbo packet length checking up-to-date with the code in net/ipv6/exthdrs.c::ipv6_hop_jumbo.

2005-11-23[BRIDGE]: recompute features when adding a new deviceOlaf Rempel
We must recompute bridge features everytime the list of underlying devices changes, or we might end up with features that are not supported by all devices (eg. NETIF_F_TSO) This patch adds the missing recompute when adding a device to the bridge. Signed-off-by: Olaf Rempel <razzor@kopf-tisch.de> Signed-off-by: David S. Miller <davem@davemloft.net>

2005-10-13[NETFILTER]: Fix OOPSes on machines with discontiguous cpu numbering.David S. Miller
Original patch by Harald Welte, with feedback from Herbert Xu and testing by Sébastien Bernard. EBTABLES, ARP tables, and IP/IP6 tables all assume that cpus are numbered linearly. That is not necessarily true. This patch fixes that up by calculating the largest possible cpu number, and allocating enough per-cpu structure space given that. Signed-off-by: David S. Miller <davem@davemloft.net>
2005-10-12[BRIDGE]: fix race on bridge del ifStephen Hemminger
This fixes the RCU race on bridge delete interface. Basically, the network device has to be detached from the bridge in the first step (pre-RCU), rather than later. At that point, no more bridge traffic will come in, and the other code will not think that network device is part of a bridge. This should also fix the XEN test problems.

2005-08-29[NET]: use __read_mostly on kmem_cache_t , DEFINE_SNMP_STAT pointersEric Dumazet
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.

2005-08-29[NETFILTER]: reduce netfilter sk_buff enlargementHarald Welte
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.

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.

2005-06-28[NETFILTER]: Fix connection tracking bug in 2.6.12Patrick McHardy
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.

2005-05-29[BRIDGE]: receive path optimizationStephen Hemminger
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>
2005-05-29[BRIDGE]: prevent bad forwarding table updatesStephen Hemminger

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!
