2013-10-14netfilter: nf_tables: expression ops overloadingPatrick McHardy
Split the expression ops into two parts and support overloading of the runtime expression ops based on the requested function through a ->select_ops() callback. This can be used to provide optimized implementations, for instance for loading small aligned amounts of data from the packet or inlining frequently used operations into the main evaluation loop.

2013-10-14netfilter: nf_tables: add netlink set APIPatrick McHardy
This patch adds the new netlink API for maintaining nf_tables sets independently of the ruleset. The API supports the following operations: - creation of sets - deletion of sets - querying of specific sets - dumping of all sets - addition of set elements - removal of set elements - dumping of all set elements Sets are identified by name, each table defines an individual namespace. The name of a set may be allocated automatically, this is mostly useful in combination with the NFT_SET_ANONYMOUS flag, which destroys a set automatically once the last reference has been released. Sets can be marked constant, meaning they're not allowed to change while linked to a rule. This allows to perform lockless operation for set types that would otherwise require locking. Additionally, if the implementation supports it, sets can (as before) be used as maps, associating a data value with each key (or range), by specifying the NFT_SET_MAP flag and can be used for interval queries by specifying the NFT_SET_INTERVAL flag. Set elements are added and removed incrementally. All element operations support batching, reducing netlink message and set lookup overhead. The old "set" and "hash" expressions are replaced by a generic "lookup" expression, which binds to the specified set. Userspace is not aware of the actual set implementation used by the kernel anymore, all configuration options are generic. Currently the implementation selection logic is largely missing and the kernel will simply use the first registered implementation supporting the requested operation. Eventually, the plan is to have userspace supply a description of the data characteristics and select the implementation based on expected performance and memory use. This patch includes the new 'lookup' expression to look up for element matching in the set. This patch includes kernel-doc descriptions for this set API and it also includes the following fixes. From Patrick McHardy: * netfilter: nf_tables: fix set element data type in dumps * netfilter: nf_tables: fix indentation of struct nft_set_elem comments * netfilter: nf_tables: fix oops in nft_validate_data_load() * netfilter: nf_tables: fix oops while listing sets of built-in tables * netfilter: nf_tables: destroy anonymous sets immediately if binding fails * netfilter: nf_tables: propagate context to set iter callback * netfilter: nf_tables: add loop detection From Pablo Neira Ayuso: * netfilter: nf_tables: allow to dump all existing sets * netfilter: nf_tables: fix wrong type for flags variable in newelem Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
2013-10-14netfilter: add nftablesPatrick McHardy
This patch adds nftables which is the intended successor of iptables. This packet filtering framework reuses the existing netfilter hooks, the connection tracking system, the NAT subsystem, the transparent proxying engine, the logging infrastructure and the userspace packet queueing facilities. In a nutshell, nftables provides a pseudo-state machine with 4 general purpose registers of 128 bits and 1 specific purpose register to store verdicts. This pseudo-machine comes with an extensible instruction set, a.k.a. "expressions" in the nftables jargon. The expressions included in this patch provide the basic functionality, they are: * bitwise: to perform bitwise operations. * byteorder: to change from host/network endianess. * cmp: to compare data with the content of the registers. * counter: to enable counters on rules. * ct: to store conntrack keys into register. * exthdr: to match IPv6 extension headers. * immediate: to load data into registers. * limit: to limit matching based on packet rate. * log: to log packets. * meta: to match metainformation that usually comes with the skbuff. * nat: to perform Network Address Translation. * payload: to fetch data from the packet payload and store it into registers. * reject (IPv4 only): to explicitly close connection, eg. TCP RST. Using this instruction-set, the userspace utility 'nft' can transform the rules expressed in human-readable text representation (using a new syntax, inspired by tcpdump) to nftables bytecode. nftables also inherits the table, chain and rule objects from iptables, but in a more configurable way, and it also includes the original datatype-agnostic set infrastructure with mapping support. This set infrastructure is enhanced in the follow up patch (netfilter: nf_tables: add netlink set API). This patch includes the following components: * the netlink API: net/netfilter/nf_tables_api.c and include/uapi/netfilter/nf_tables.h * the packet filter core: net/netfilter/nf_tables_core.c * the expressions (described above): net/netfilter/nft_*.c * the filter tables: arp, IPv4, IPv6 and bridge: net/ipv4/netfilter/nf_tables_ipv4.c net/ipv6/netfilter/nf_tables_ipv6.c net/ipv4/netfilter/nf_tables_arp.c net/bridge/netfilter/nf_tables_bridge.c * the NAT table (IPv4 only): net/ipv4/netfilter/nf_table_nat_ipv4.c * the route table (similar to mangle): net/ipv4/netfilter/nf_table_route_ipv4.c net/ipv6/netfilter/nf_table_route_ipv6.c * internal definitions under: include/net/netfilter/nf_tables.h include/net/netfilter/nf_tables_core.h * It also includes an skeleton expression: net/netfilter/nft_expr_template.c and the preliminary implementation of the meta target net/netfilter/nft_meta_target.c It also includes a change in struct nf_hook_ops to add a new pointer to store private data to the hook, that is used to store the rule list per chain. This patch is based on the patch from Patrick McHardy, plus merged accumulated cleanups, fixes and small enhancements to the nftables code that has been done since 2009, which are: From Patrick McHardy: * nf_tables: adjust netlink handler function signatures * nf_tables: only retry table lookup after successful table module load * nf_tables: fix event notification echo and avoid unnecessary messages * nft_ct: add l3proto support * nf_tables: pass expression context to nft_validate_data_load() * nf_tables: remove redundant definition * nft_ct: fix maxattr initialization * nf_tables: fix invalid event type in nf_tables_getrule() * nf_tables: simplify nft_data_init() usage * nf_tables: build in more core modules * nf_tables: fix double lookup expression unregistation * nf_tables: move expression initialization to nf_tables_core.c * nf_tables: build in payload module * nf_tables: use NFPROTO constants * nf_tables: rename pid variables to portid * nf_tables: save 48 bits per rule * nf_tables: introduce chain rename * nf_tables: check for duplicate names on chain rename * nf_tables: remove ability to specify handles for new rules * nf_tables: return error for rule change request * nf_tables: return error for NLM_F_REPLACE without rule handle * nf_tables: include NLM_F_APPEND/NLM_F_REPLACE flags in rule notification * nf_tables: fix NLM_F_MULTI usage in netlink notifications * nf_tables: include NLM_F_APPEND in rule dumps From Pablo Neira Ayuso: * nf_tables: fix stack overflow in nf_tables_newrule * nf_tables: nft_ct: fix compilation warning * nf_tables: nft_ct: fix crash with invalid packets * nft_log: group and qthreshold are 2^16 * nf_tables: nft_meta: fix socket uid,gid handling * nft_counter: allow to restore counters * nf_tables: fix module autoload * nf_tables: allow to remove all rules placed in one chain * nf_tables: use 64-bits rule handle instead of 16-bits * nf_tables: fix chain after rule deletion * nf_tables: improve deletion performance * nf_tables: add missing code in route chain type * nf_tables: rise maximum number of expressions from 12 to 128 * nf_tables: don't delete table if in use * nf_tables: fix basechain release From Tomasz Bursztyka: * nf_tables: Add support for changing users chain's name * nf_tables: Change chain's name to be fixed sized * nf_tables: Add support for replacing a rule by another one * nf_tables: Update uapi nftables netlink header documentation From Florian Westphal: * nft_log: group is u16, snaplen u32 From Phil Oester: * nf_tables: operational limit match Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>

2013-10-12batman-adv: create common header for ICMP packetsAntonio Quartulli
the icmp and the icmp_rr packets share the same initial fields since they use the same code to be processed and forwarded. Extract the common fields and put them into a separate struct so that future ICMP packets can be easily added without bloating the packet definition. However, keep the seqno field outside of the newly created common header because future ICMP types may require a bigger sequence number space.

2013-10-12batman-adv: use htons when possibleAntonio Quartulli

There are cards out there with the same PCI id and a BCM4311, which is a pre ieee80211n chip only supporting ieee80211a, these are still not supported by b43 and not detected by ssb.

2013-10-10bcma: reject PCI cards in bcma.Hauke Mehrtens
bcma currently only supports PCIe cards and no PCI cards, reject them if we find them. I have never heard of any PCI card using the AI bus (bcma), all of them are using ssb instead. Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de> Signed-off-by: John W. Linville <linville@tuxdriver.com>

2013-10-10rt2x00_pci: Fix interrupt handler name (visible at /proc/interrupts)Kirill Tkhai
Currently driver name is wrong. PCI device address is visible at /proc/interrupts instead of the name: 43: 124 0 0 0 PCI-MSI-edge rtsx_pci 44: 384 0 0 0 PCI-MSI-edge snd_hda_intel 45: 25096 0 0 0 PCI-MSI-edge 0000:01:00.0 ^^^^^^^^^^^^ So, pass the right name. rt2x00_ops->name contains KBUILD_MODNAME and good for that, so pass it. Handler names will be "rt2500pci", "rt2500pci" etc. Signed-off-by: Kirill Tkhai <tkhai@yandex.ru> CC: Ivo van Doorn <IvDoorn@gmail.com> CC: Gertjan van Wingerde <gwingerde@gmail.com> CC: Helmut Schaa <helmut.schaa@googlemail.com> CC: linux-wireless@vger.kernel.org Acked-by: Stanislaw Gruszka <sgruszka@redhat.com> Signed-off-by: John W.

2013-10-09i40e: Add support for 64 bit netstatsAlexander Duyck
This change brings support for 64 bit netstats to the driver. Previously the stats were 64 bit but highly racy due to the fact that 64 bit transactions are not atomic on 32 bit systems. This change makes is so that the 64 bit byte and packet stats are reliable on all architectures.

2013-10-09i40e: Move rings from pointer to array to array of pointersAlexander Duyck
Allocate the queue pairs individually instead of as a group. This allows for much easier queue management as it is possible to dynamically resize the queues without having to free and allocate the entire block. Ease statistic collection by treating Tx/Rx queue pairs as a single unit. Each pair is allocated together and starts with a Tx queue and ends with an Rx queue. By ordering them this way it is possible to know the Rx offset based on a pointer to the Tx queue.
