* [NETFILTER] x_tables: Abstraction layer for {ip,ip6,arp}_tablesHarald Welte2006-01-12
| | | | | | | | | | | | | | | | | | | | | | | | | This monster-patch tries to do the best job for unifying the data structures and backend interfaces for the three evil clones ip_tables, ip6_tables and arp_tables. In an ideal world we would never have allowed this kind of copy+paste programming... but well, our world isn't (yet?) ideal. o introduce a new x_tables module o {ip,arp,ip6}_tables depend on this x_tables module o registration functions for tables, matches and targets are only wrappers around x_tables provided functions o all matches/targets that are used from ip_tables and ip6_tables are now implemented as xt_FOOBAR.c files and provide module aliases to ipt_FOOBAR and ip6t_FOOBAR o header files for xt_matches are in include/linux/netfilter/, include/linux/netfilter_{ipv4,ipv6} contains compatibility wrappers around the xt_FOOBAR.h headers Based on this patchset we're going to further unify the code, gradually getting rid of all the layer 3 specific assumptions.

* [BRIDGE] netfilter: vlan + hw checksum = bug?Stephen Hemminger2006-01-06
| | | | | | | | | | | | It looks like the bridge netfilter code does not correctly update the hardware checksum after popping off the VLAN header. This is by inspection, I have *not* tested this. To test you would need to set up a filtering bridge with vlans and a device the does hardware receive checksum (skge, or sungem) Signed-off-by: Stephen Hemminger <shemminger@osdl.org> Signed-off-by: David S.

* | [BRIDGE]: handle speed detection after carrier changesStephen Hemminger2006-01-03
| | | | | | | | | | | | | | | | | | | | | | | | Speed of a interface may not be available until carrier is detected in the case of autonegotiation. To get the correct value we need to recheck speed after carrier event. But the check needs to be done in a context that is similar to normal ethtool interface (can sleep). Also, delay check for 1ms to try avoid any carrier bounce transitions. Signed-off-by: Stephen Hemminger <shemminger@osdl.org> Signed-off-by: David S. Miller <davem@davemloft.net>
* | [BRIDGE]: allow setting hardware address of bridge pseudo-devStephen Hemminger2006-01-03
| | | | | | | | | | | | | | | | | | | | Some people are using bridging to hide multiple machines from an ISP that restricts by MAC address. So in that case allow the bridge mac address to be set to any of the existing interfaces. I don't want to allow any arbitrary value and confuse STP.

* [BR_NETFILTER]: Fix leak if skb traverses > 1 bridgeDavid Kimdon2005-12-26

* [BRIDGE]: recompute features when adding a new deviceOlaf Rempel2005-11-23

* [NETFILTER]: Fix OOPSes on machines with discontiguous cpu numbering.David S. Miller2005-10-13
| | | | | | | | | | | | | | 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>
* [BRIDGE]: fix race on bridge del ifStephen Hemminger2005-10-12
| | | | | | | | | | | | | 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.

| | | | | | | | | | | | | 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.

* [NETFILTER]: reduce netfilter sk_buff enlargementHarald Welte2005-08-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Ravnborg2005-07-12
| | | | | | | | | | | | | | | | | 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 McHardy2005-06-28
| | | | | | | | | | | | | | | 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 Hemminger2005-05-29

* Linux-2.6.12-rc2v2.6.12-rc2Linus Torvalds2005-04-16
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!
