2018-12-19net: convert bridge_nf to use skb extension infrastructureFlorian Westphal1-2/+2
This converts the bridge netfilter (calling iptables hooks from bridge) facility to use the extension infrastructure. The bridge_nf specific hooks in skb clone and free paths are removed, they have been replaced by the skb_ext hooks that do the same as the bridge nf allocations hooks did.

2018-08-03netfilter: bridge: Expose nf_tables bridge hook priorities through uapiMáté Eckl1-11/+0
Netfilter exposes standard hook priorities in case of ipv4, ipv6 and arp but not in case of bridge. This patch exposes the hook priority values of the bridge family (which are different from the formerly mentioned) via uapi so that they can be used by user-space applications just like the others.

2017-11-02License cleanup: add SPDX GPL-2.0 license identifier to files with no licenseGreg Kroah-Hartman1-0/+1
Many source files in the tree are missing licensing information, which makes it harder for compliance tools to determine the correct license. By default all files without license information are under the default license of the kernel, which is GPL version 2. Update the files which contain no license information with the 'GPL-2.0' SPDX license identifier. The SPDX identifier is a legally binding shorthand, which can be used instead of the full boiler plate text. This patch is based on work done by Thomas Gleixner and Kate Stewart and Philippe Ombredanne. How this work was done: Patches were generated and checked against linux-4.14-rc6 for a subset of the use cases: - file had no licensing information it it. - file was a */uapi/* one with no licensing information in it, - file was a */uapi/* one with existing licensing information, Further patches will be generated in subsequent months to fix up cases where non-standard license headers were used, and references to license had to be inferred by heuristics based on keywords. The analysis to determine which SPDX License Identifier to be applied to a file was done in a spreadsheet of side by side results from of the output of two independent scanners (ScanCode & Windriver) producing SPDX tag:value files created by Philippe Ombredanne. Philippe prepared the base worksheet, and did an initial spot review of a few 1000 files. The 4.13 kernel was the starting point of the analysis with 60,537 files assessed. Kate Stewart did a file by file comparison of the scanner results in the spreadsheet to determine which SPDX license identifier(s) to be applied to the file. She confirmed any determination that was not immediately clear with lawyers working with the Linux Foundation. Criteria used to select files for SPDX license identifier tagging was: - Files considered eligible had to be source code files. - Make and config files were included as candidates if they contained >5 lines of source - File already had some variant of a license header in it (even if <5 lines). All documentation files were explicitly excluded. The following heuristics were used to determine which SPDX license identifiers to apply. - when both scanners couldn't find any license traces, file was considered to have no license information in it, and the top level COPYING file license applied. For non */uapi/* files that summary was: SPDX license identifier # files ---------------------------------------------------|------- GPL-2.0 11139 and resulted in the first patch in this series. If that file was a */uapi/* path one, it was "GPL-2.0 WITH Linux-syscall-note" otherwise it was "GPL-2.0". Results of that was: SPDX license identifier # files ---------------------------------------------------|------- GPL-2.0 WITH Linux-syscall-note 930 and resulted in the second patch in this series. - if a file had some form of licensing information in it, and was one of the */uapi/* ones, it was denoted with the Linux-syscall-note if any GPL family license was found in the file or had no licensing in it (per prior point). Results summary: SPDX license identifier # files ---------------------------------------------------|------ GPL-2.0 WITH Linux-syscall-note 270 GPL-2.0+ WITH Linux-syscall-note 169 ((GPL-2.0 WITH Linux-syscall-note) OR BSD-2-Clause) 21 ((GPL-2.0 WITH Linux-syscall-note) OR BSD-3-Clause) 17 LGPL-2.1+ WITH Linux-syscall-note 15 GPL-1.0+ WITH Linux-syscall-note 14 ((GPL-2.0+ WITH Linux-syscall-note) OR BSD-3-Clause) 5 LGPL-2.0+ WITH Linux-syscall-note 4 LGPL-2.1 WITH Linux-syscall-note 3 ((GPL-2.0 WITH Linux-syscall-note) OR MIT) 3 ((GPL-2.0 WITH Linux-syscall-note) AND MIT) 1 and that resulted in the third patch in this series. - when the two scanners agreed on the detected license(s), that became the concluded license(s). - when there was disagreement between the two scanners (one detected a license but the other didn't, or they both detected different licenses) a manual inspection of the file occurred. - In most cases a manual inspection of the information in the file resulted in a clear resolution of the license that should apply (and which scanner probably needed to revisit its heuristics). - When it was not immediately clear, the license identifier was confirmed with lawyers working with the Linux Foundation. - If there was any question as to the appropriate license identifier, the file was flagged for further research and to be revisited later in time. In total, over 70 hours of logged manual review was done on the spreadsheet to determine the SPDX license identifiers to apply to the source files by Kate, Philippe, Thomas and, in some cases, confirmation by lawyers working with the Linux Foundation. Kate also obtained a third independent scan of the 4.13 code base from FOSSology, and compared selected files where the other two scanners disagreed against that SPDX file, to see if there was new insights. The Windriver scanner is based on an older version of FOSSology in part, so they are related. Thomas did random spot checks in about 500 files from the spreadsheets for the uapi headers and agreed with SPDX license identifier in the files he inspected. For the non-uapi files Thomas did random spot checks in about 15000 files. In initial set of patches against 4.14-rc6, 3 files were found to have copy/paste license identifier errors, and have been fixed to reflect the correct identifier. Additionally Philippe spent 10 hours this week doing a detailed manual inspection and review of the 12,461 patched files from the initial patch version early this week with: - a full scancode scan run, collecting the matched texts, detected license ids and scores - reviewing anything where there was a license detected (about 500+ files) to ensure that the applied SPDX license was correct - reviewing anything where there was no detection but the patch license was not GPL-2.0 WITH Linux-syscall-note to ensure that the applied SPDX license was correct This produced a worksheet with 20 files needing minor correction. This worksheet was then exported into 3 different .csv files for the different types of files to be modified. These .csv files were then reviewed by Greg. Thomas wrote a script to parse the csv files and add the proper SPDX tag to the file, in the format that the file expected. This script was further refined by Greg based on the output to detect more types of files automatically and to distinguish between header and source .c files (which need different comment types.) Finally Greg ran the script using the .csv files to generate the patches.

2015-09-17netfilter: Pass net into okfnEric W. Biederman1-1/+1
This is immediately motivated by the bridge code that chains functions that call into netfilter. Without passing net into the okfns the bridge code would need to guess about the best expression for the network namespace to process packets in. As net is frequently one of the first things computed in continuation functions after netfilter has done it's job passing in the desired network namespace is in many cases a code simplification. To support this change the function dst_output_okfn is introduced to simplify passing dst_output as an okfn. For the moment dst_output_okfn just silently drops the struct net. Signed-off-by: "Eric W.

Therefore we no longer need to care about 'encapsulation' overhead of stripped PPPOE/VLAN headers since ip_do_fragment doesn't use device mtu in such cases.

2015-04-08netfilter: bridge: make BRNF_PKT_TYPE flag a boolFlorian Westphal1-1/+0
nf_bridge_info->mask is used for several things, for example to remember if skb->pkt_type was set to OTHER_HOST. For a bridge, OTHER_HOST is expected case. For ip forward its a non-starter though -- routing expects PACKET_HOST. Bridge netfilter thus changes OTHER_HOST to PACKET_HOST before hook invocation and then un-does it after hook traversal. This information is irrelevant outside of br_netfilter. After this change, ->mask now only contains flags that need to be known outside of br_netfilter in fast-path. Future patch changes mask into a 2bit state field in sk_buff, so that we can remove skb->nf_bridge pointer for good and consider all remaining places that access nf_bridge info content a not-so fastpath.

2015-04-08netfilter: bridge: start splitting mask into public/private chunksFlorian Westphal1-3/+1
->mask is a bit info field that mixes various use cases. In particular, we have flags that are mutually exlusive, and flags that are only used within br_netfilter while others need to be exposed to other parts of the kernel. Remove BRNF_8021Q/PPPoE flags. They're mutually exclusive and only needed within br_netfilter context. Signed-off-by: Florian Westphal <fw@strlen.de> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
2015-04-08netfilter: bridge: add helpers for fetching physin/outdevFlorian Westphal1-1/+22
right now we store this in the nf_bridge_info struct, accessible via skb->nf_bridge. This patch prepares removal of this pointer from skb: Instead of using skb->nf_bridge->x, we use helpers to obtain the in/out device (or ifindexes). Followup patches to netfilter will then allow nf_bridge_info to be obtained by a call into the br_netfilter core, rather than keeping a pointer to it in sk_buff.

2015-04-07netfilter: Pass socket pointer down through okfn().David Miller1-1/+1
On the output paths in particular, we have to sometimes deal with two socket contexts. First, and usually skb->sk, is the local socket that generated the frame. And second, is potentially the socket used to control a tunneling socket, such as one the encapsulates using UDP. We do not want to disassociate skb->sk when encapsulating in order to fix this, because that would break socket memory accounting. The most extreme case where this can cause huge problems is an AF_PACKET socket transmitting over a vxlan device. We hit code paths doing checks that assume they are dealing with an ipv4 socket, but are actually operating upon the AF_PACKET one. Signed-off-by: David S. Miller <davem@davemloft.net>
2015-03-22netfilter: bridge: kill nf_bridge_padFlorian Westphal1-22/+0

Its not needed anymore since 2bf540b73ed5b ([NETFILTER]: bridge-netfilter: remove deferred hooks). Before this it was possible to have physoutdev set for locally generated packets -- this isn't the case anymore: BRNF_STATE_BRIDGED flag is set when we assign nf_bridge->physoutdev, so physoutdev != NULL means BRNF_STATE_BRIDGED is set. If physoutdev is NULL, then we are looking at locally-delivered and routed packet. Signed-off-by: Florian Westphal <fw@strlen.de> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>

2014-09-26netfilter: bridge: move br_netfilter out of the corePablo Neira Ayuso1-1/+1
Jesper reported that br_netfilter always registers the hooks since this is part of the bridge core. This harms performance for people that don't need this. This patch modularizes br_netfilter so it can be rmmod'ed, thus, the hooks can be unregistered. I think the bridge netfilter should have been a separated module since the beginning, Patrick agreed on that. Note that this is breaking compatibility for users that expect that bridge netfilter is going to be available after explicitly 'modprobe bridge' or via automatic load through brctl. However, the damage can be easily undone by modprobing br_netfilter. The bridge core also spots a message to provide a clue to people that didn't notice that this has been deprecated. On top of that, the plan is that nftables will not rely on this software layer, but integrate the connection tracking into the bridge layer to enable stateful filtering and NAT, which is was bridge netfilter users seem to require. This patch still keeps the fake_dst_ops in the bridge core, since this is required by when the bridge port is initialized. So we can safely modprobe/rmmod br_netfilter anytime.

2010-04-20netfilter: bridge-netfilter: fix refragmenting IP traffic encapsulated in PPPoE trafficBart De Schuymer1-0/+7
The MTU for IP traffic encapsulated inside PPPoE traffic is smaller than the MTU of the Ethernet device (1500). Connection tracking gathers all IP packets and sometimes will refragment them in ip_fragment(). We then need to subtract the length of the encapsulating header from the mtu used in ip_fragment(). The check in br_nf_dev_queue_xmit() which determines if ip_fragment() has to be called is also updated for the PPPoE-encapsulated packets. nf_bridge_copy_header() is also updated to make sure the PPPoE data length field has the correct value.

2010-04-15netfilter: bridge-netfilter: Fix MAC header handling with IP DNATBart De Schuymer1-1/+4
- fix IP DNAT on vlan- or pppoe-encapsulated traffic: The functions neigh_hh_output() or dst->neighbour->output() overwrite the complete Ethernet header, although we only need the destination MAC address. For encapsulated packets, they ended up overwriting the encapsulating header. The new code copies the Ethernet source MAC address and protocol number before calling dst->neighbour->output(). The Ethernet source MAC and protocol number are copied back in place in br_nf_pre_routing_finish_bridge_slow(). This also makes the IP DNAT more transparent because in the old scheme the source MAC of the bridge was copied into the source address in the Ethernet header. We also let skb->protocol equal ETH_P_IP resp. ETH_P_IPV6 during the execution of the PF_INET resp. PF_INET6 hooks. - Speed up IP DNAT by calling neigh_hh_bridge() instead of neigh_hh_output(): if dst->hh is available, we already know the MAC address so we can just copy it.

2007-12-14[NETFILTER]: bridge: fix missing link layer headers on outgoing routed packetsPatrick McHardy1-1/+2
As reported by Damien Thebault, the double POSTROUTING hook invocation fix caused outgoing packets routed between two bridges to appear without a link-layer header. The reason for this is that we're skipping the br_nf_post_routing hook for routed packets now and don't save the original link layer header, but nevertheless tries to restore it on output, causing corruption. The root cause for this is that skb->nf_bridge has no clearly defined lifetime and is used to indicate all kind of things, but that is quite complicated to fix. For now simply don't touch these packets and handle them like packets from any other device.

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.
