We don't need to pull the full definitions in that file, a simple forward declaration is enough. Moreover, include linux/procfs.h from nf_synproxy_core, otherwise this hits a compilation error due to missing declarations, ie. net/netfilter/nf_synproxy_core.c: In function ‘synproxy_proc_init’: net/netfilter/nf_synproxy_core.c:326:2: error: implicit declaration of function ‘proc_create’ [-Werror=implicit-function-declaration] if (!proc_create("synproxy", S_IRUGO, net->proc_net_stat, ^ Signed-off-by:Pablo Neira Ayuso <pablo@netfilter.org> Signed-off-by:

Let's force a 16 bytes alignment on xt_counter percpu allocations, so that bytes and packets sit in same cache line. xt_counter being exported to user space, we cannot add __align(16) on the structure itself. Signed-off-by:

xt_socket is useful for matching sockets with IP_TRANSPARENT and taking some action on the matching packets. However, it lacks the ability to match only a small subset of transparent sockets. Suppose there are 2 applications, each with its own set of transparent sockets. The first application wants all matching packets dropped, while the second application wants them forwarded somewhere else. Add the ability to retore the skb->mark from the sk_mark. The mark is only restored if a matching socket is found and the transparent / nowildcard conditions are satisfied. Now the 2 hypothetical applications can differentiate their sockets based on a mark value set with SO_MARK. iptables -t mangle -I PREROUTING -m socket --transparent \ --restore-skmark -j action iptables -t mangle -A action -m mark --mark 10 -j action2 iptables -t mangle -A action -m mark --mark 11 -j action3 Signed-off-by:Harout Hedeshian <harouth@codeaurora.org> Signed-off-by:

This patch adds an additional attribute when sending packet information via netlink in netfilter_queue module. It will send additional security context data, so that userspace applications can verify this context against their own security databases. Signed-off-by:

Craig Gallek says: ==================== Socket destruction events via netlink sock_diag This series extends the netlink sock_diag interface to broadcast socket information as they are being destroyed. The current interface is poll based and can not be used to retreive information about sockets that are destroyed between poll intervals. Only inet sockets are broadcast in this implementation, but other families could easily be added as needed in the future. If this patch set is accepted, a follow-up patch to the ss utility in the iproute2 suite will also be submitted. ==================== Signed-off-by: -
Craig Gallek authored
This get_info handler will simply dispatch to the appropriate existing inet protocol handler. This patch also includes a new netlink attribute (INET_DIAG_PROTOCOL). This attribute is currently only used for multicast messages. Without this attribute, there is no way of knowing the IP protocol used by the socket information being broadcast. This attribute is not necessary in the 'dump' variant of this protocol (though it could easily be added) because dump requests are issued for specific family/protocol pairs. Tested: ss -E (note, the -E option has not yet been merged into the upstream version of ss). Signed-off-by:

Previously, there was no clear distinction between the inet protocols that used struct tcp_info to report information and those that didn't. This change adds a specific size attribute to the inet_diag_handler struct which defines these interfaces. This will make dispatching sock_diag get_info requests identical for all inet protocols in a following patch. Tested: ss -au Tested: ss -at Signed-off-by:

These groups will contain socket-destruction events for AF_INET/AF_INET6, IPPROTO_TCP/IPPROTO_UDP. Near the end of socket destruction, a check for listeners is performed. In the presence of a listener, rather than completely cleanup the socket, a unit of work will be added to a private work queue which will first broadcast information about the socket and then finish the cleanup operation.

Or Gerlitz says: ==================== mlx4 driver update (+ new VF ndo) This series from Eran and Hadar is further dealing with traffic counters in the mlx4 driver, this time mostly around SRIOV. We added a new ndo to read the VF counters through the PF netdev netlink infrastructure plus mlx4 implementation for that ndo. changes from V0: - applied feedback from John to use nested netlink encoding for the VF counters so we can extend it later - add handling of single ported VFs in the mlx4_en driver new ndo - avoid chopping the FW counters from 64 to 32 bits in mlx4_en PF flow ==================== Signed-off-by: -

This is an infrastructure step to attach all the QPs opened from the IB driver to a counter in order to collect VF stats from the PF using those counters. If the port's type is Ethernet, the counter policy demands two counters per port (one for RoCE and one for Ethernet). The port default counter (allocated in mlx4_core) is used for the Ethernet netdev QPs and we allocate another counter for RoCE. If the port's traffic is Infiniband, the counter policy demands one counter per port, so it can use the port's default counter. Also, Add 'allocated' flag for each counter in order to clean it at unload. Signed-off-by:

Each physical function has a guarantee of two counters per port, one for a default counter and one for the IB driver. Each virtual function has a guarantee of one counter per port. All other counters are free and can be obtained on demand. This is a preparation step for supporting a get_vf_stats ndo call, so we can promise a counter for every VF in order to collect their statistics from the PF context. Signed-off-by:

Reserve the last valid counter index for "sink" counter, when a new counter cannot be allocated, the driver will use this counter. In order to avoid allocating this counter on any other flow, fix the indices bitmap allocation range, and reserve the sink counter index. Add macro for the sink counter index and replace all appearences of the index with the macro. Signed-off-by:

We need to delete from offload the device externally learnded fdbs when any one of these events happen: 1) Bridge ages out fdb. (When bridge is doing ageing vs. device doing ageing. If device is doing ageing, it would send SWITCHDEV_FDB_DEL directly). 2) STP state change flushes fdbs on port. 3) User uses sysfs interface to flush fdbs from bridge or bridge port: echo 1 >/sys/class/net/BR_DEV/bridge/flush echo 1 >/sys/class/net/BR_PORT/brport/flush 4) Offload driver send event SWITCHDEV_FDB_DEL to delete fdb entry. For rocker, we can now get called to delete fdb entry in wait and nowait contexts, so set NOWAIT flag when deleting fdb entry. Signed-off-by:

Samuel Ortiz says: ==================== NFC 4.2 pull request This is the NFC pull request for 4.2. - NCI drivers can now define their own handlers for processing proprietary NCI responses and notifications. - NFC vendors can use a dedicated netlink API to send their own proprietary commands, like e.g. all commands needed to implement vendor specific manufacturing tools. - A new generic NCI over UART driver against which any NCI chipset running on top of a serial interface can register. - The st21nfcb driver is renamed to st-nci as it can and will support most of ST Microelectronics NCI chipsets. - The st21nfcb driver can put its CLF in hibernate mode and save significant amount of power. - A few st21nfcb minor fixes. - The NXP NCI driver now supports ACPI enumeration. - The Marvell NCI driver now supports both USB and serial physical interfaces. - The Marvell NCI drivers also supports NCI frames being muxed over HCI.

Scott Feldman says: ==================== rocker: revert back to support for nowait processes One of the items removed from the rocker driver in the Spring Cleanup patch series was the ability to mark processing in the driver as "no wait" for those contexts where we cannot sleep. Turns out, we have "no wait" contexts where we want to program the device and we don't want to defer the processing to a process context. So re-add the ROCKER_OP_FLAG_NOWAIT flag to mark such processes, and propagate flags to mem allocator and to the device cmd executor. With NOWAIT, mem allocs are GFP_ATOMIC and device cmds are queued to the device, but the driver will not wait (sleep) for the response back from the device. My bad for removing NOWAIT support in the first place; I thought we could swing non-sleep contexts to process context using a work queue, for example, but there is push-back to keep processing in original context. ==================== Signed-off-by: -
