netfilter: restore rule tracing via nfnetlink_log

2015-03-19T10:14:48Z

Since fab4085 ("netfilter: log: nf_log_packet() as real unified interface"), the loginfo structure that is passed to nf_log_packet() is used to explicitly indicate the logger type you want to use. This is a problem for people tracing rules through nfnetlink_log since packets are always routed to the NF_LOG_TYPE logger after the aforementioned patch. We can fix this by removing the trace loginfo structures, but that still changes the log level from 4 to 5 for tracing messages and there may be someone relying on this outthere. So let's just introduce a new nf_log_trace() function that restores the former behaviour. Reported-by: Markus Kötter Signed-off-by: Pablo Neira Ayuso

netfilter: nf_tables: fix userdata length overflow

2015-03-04T17:46:06Z

The NFT_USERDATA_MAXLEN is defined to 256, however we only have a u8 to store its size. Introduce a struct nft_userdata which contains a length field and indicate its presence using a single bit in the rule. The length field of struct nft_userdata is also a u8, however we don't store zero sized data, so the actual length is udata->len + 1. Signed-off-by: Patrick McHardy Signed-off-by: Pablo Neira Ayuso

Conflicts: drivers/net/vxlan.c drivers/vhost/net.c include/linux/if_vlan.h net/core/dev.c The net/core/dev.c conflict was the overlap of one commit marking an existing function static whilst another was adding a new function. In the include/linux/if_vlan.h case, the type used for a local variable was changed in 'net', whereas the function got rewritten to fix a stacked vlan bug in 'net-next'. In drivers/vhost/net.c, Al Viro's iov_iter conversions in 'net-next' overlapped with an endainness fix for VHOST 1.0 in 'net'. In drivers/net/vxlan.c, vxlan_find_vni() added a 'flags' parameter in 'net-next' whereas in 'net' there was a bug fix to pass in the correct network namespace pointer in calls to this function.

netfilter: nf_tables: validate hooks in NAT expressions

2015-01-19T13:52:39Z

The user can crash the kernel if it uses any of the existing NAT expressions from the wrong hook, so add some code to validate this when loading the rule. This patch introduces nft_chain_validate_hooks() which is based on an existing function in the bridge version of the reject expression. Signed-off-by: Pablo Neira Ayuso

netfilter: conntrack: Remove nf_ct_conntrack_flush_report

2015-01-08T11:16:58Z

The only user of nf_ct_conntrack_flush_report() was ctnetlink_del_conntrack(). After adding support for flushing connections with a given mark, this function is no longer called. Signed-off-by: Kristian Evensen Signed-off-by: Pablo Neira Ayuso

Pull networking updates from David Miller: 1) New offloading infrastructure and example 'rocker' driver for offloading of switching and routing to hardware. This work was done by a large group of dedicated individuals, not limited to: Scott Feldman, Jiri Pirko, Thomas Graf, John Fastabend, Jamal Hadi Salim, Andy Gospodarek, Florian Fainelli, Roopa Prabhu 2) Start making the networking operate on IOV iterators instead of modifying iov objects in-situ during transfers. Thanks to Al Viro and Herbert Xu. 3) A set of new netlink interfaces for the TIPC stack, from Richard Alpe. 4) Remove unnecessary looping during ipv6 routing lookups, from Martin KaFai Lau. 5) Add PAUSE frame generation support to gianfar driver, from Matei Pavaluca. 6) Allow for larger reordering levels in TCP, which are easily achievable in the real world right now, from Eric Dumazet. 7) Add a variable of napi_schedule that doesn't need to disable cpu interrupts, from Eric Dumazet. 8) Use a doubly linked list to optimize neigh_parms_release(), from Nicolas Dichtel. 9) Various enhancements to the kernel BPF verifier, and allow eBPF programs to actually be attached to sockets. From Alexei Starovoitov. 10) Support TSO/LSO in sunvnet driver, from David L Stevens. 11) Allow controlling ECN usage via routing metrics, from Florian Westphal. 12) Remote checksum offload, from Tom Herbert. 13) Add split-header receive, BQL, and xmit_more support to amd-xgbe driver, from Thomas Lendacky. 14) Add MPLS support to openvswitch, from Simon Horman. 15) Support wildcard tunnel endpoints in ipv6 tunnels, from Steffen Klassert. 16) Do gro flushes on a per-device basis using a timer, from Eric Dumazet. This tries to resolve the conflicting goals between the desired handling of bulk vs. RPC-like traffic. 17) Allow userspace to ask for the CPU upon what a packet was received/steered, via SO_INCOMING_CPU. From Eric Dumazet. 18) Limit GSO packets to half the current congestion window, from Eric Dumazet. 19) Add a generic helper so that all drivers set their RSS keys in a consistent way, from Eric Dumazet. 20) Add xmit_more support to enic driver, from Govindarajulu Varadarajan. 21) Add VLAN packet scheduler action, from Jiri Pirko. 22) Support configurable RSS hash functions via ethtool, from Eyal Perry. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-next: (1820 commits) Fix race condition between vxlan_sock_add and vxlan_sock_release net/macb: fix compilation warning for print_hex_dump() called with skb->mac_header net/mlx4: Add support for A0 steering net/mlx4: Refactor QUERY_PORT net/mlx4_core: Add explicit error message when rule doesn't meet configuration net/mlx4: Add A0 hybrid steering net/mlx4: Add mlx4_bitmap zone allocator net/mlx4: Add a check if there are too many reserved QPs net/mlx4: Change QP allocation scheme net/mlx4_core: Use tasklet for user-space CQ completion events net/mlx4_core: Mask out host side virtualization features for guests net/mlx4_en: Set csum level for encapsulated packets be2net: Export tunnel offloads only when a VxLAN tunnel is created gianfar: Fix dma check map error when DMA_API_DEBUG is enabled cxgb4/csiostor: Don't use MASTER_MUST for fw_hello call net: fec: only enable mdio interrupt before phy device link up net: fec: clear all interrupt events to support i.MX6SX net: fec: reset fep link status in suspend function net: sock: fix access via invalid file descriptor net: introduce helper macro for_each_cmsghdr ...

netfilter: conntrack: avoid zeroing timer

2014-11-27T11:41:06Z

add a __nfct_init_offset annotation member to struct nf_conn to make it clear which members are covered by the memset when the conntrack is allocated. This avoids zeroing timer_list and ct_net; both are already inited explicitly. Signed-off-by: Florian Westphal Signed-off-by: Pablo Neira Ayuso
