2015-06-10mac80211: convert HW flags to unsigned long bitmapJohannes Berg1-4/+3
As we're running out of hardware capability flags pretty quickly, convert them to use the regular test_bit() style unsigned long bitmaps. This introduces a number of helper functions/macros to set and to test the bits, along with new debugfs code. The occurrences of an explicit __clear_bit() are intentional, the drivers were never supposed to change their supported bits on the fly. We should investigate changing this to be a per-frame flag.

2015-04-24mac80211: remove support for IFF_PROMISCJohannes Berg2-5/+2
This support is essentially useless as typically networks are encrypted, frames will be filtered by hardware, and rate scaling will be done with the intended recipient in mind. For real monitoring of the network, the monitor mode support should be used instead. Removing it removes a lot of corner cases. Signed-off-by: Johannes Berg <johannes.berg@intel.com>

Pull networking updates from David Miller: 1) Add BQL support to via-rhine, from Tino Reichardt. 2) Integrate SWITCHDEV layer support into the DSA layer, so DSA drivers can support hw switch offloading. From Floria Fainelli. 3) Allow 'ip address' commands to initiate multicast group join/leave, from Madhu Challa. 4) Many ipv4 FIB lookup optimizations from Alexander Duyck. 5) Support EBPF in cls_bpf classifier and act_bpf action, from Daniel Borkmann. 6) Remove the ugly compat support in ARP for ugly layers like ax25, rose, etc. And use this to clean up the neigh layer, then use it to implement MPLS support. All from Eric Biederman. 7) Support L3 forwarding offloading in switches, from Scott Feldman. 8) Collapse the LOCAL and MAIN ipv4 FIB tables when possible, to speed up route lookups even further. From Alexander Duyck. 9) Many improvements and bug fixes to the rhashtable implementation, from Herbert Xu and Thomas Graf. In particular, in the case where an rhashtable user bulk adds a large number of items into an empty table, we expand the table much more sanely. 10) Don't make the tcp_metrics hash table per-namespace, from Eric Biederman. 11) Extend EBPF to access SKB fields, from Alexei Starovoitov. 12) Split out new connection request sockets so that they can be established in the main hash table. Much less false sharing since hash lookups go direct to the request sockets instead of having to go first to the listener then to the request socks hashed underneath. From Eric Dumazet. 13) Add async I/O support for crytpo AF_ALG sockets, from Tadeusz Struk. 14) Support stable privacy address generation for RFC7217 in IPV6. From Hannes Frederic Sowa. 15) Hash network namespace into IP frag IDs, also from Hannes Frederic Sowa. 16) Convert PTP get/set methods to use 64-bit time, from Richard Cochran. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-next: (1816 commits) fm10k: Bump driver version to 0.15.2 fm10k: corrected VF multicast update fm10k: mbx_update_max_size does not drop all oversized messages fm10k: reset head instead of calling update_max_size fm10k: renamed mbx_tx_dropped to mbx_tx_oversized fm10k: update xcast mode before synchronizing multicast addresses fm10k: start service timer on probe fm10k: fix function header comment fm10k: comment next_vf_mbx flow fm10k: don't handle mailbox events in iov_event path and always process mailbox fm10k: use separate workqueue for fm10k driver fm10k: Set PF queues to unlimited bandwidth during virtualization fm10k: expose tx_timeout_count as an ethtool stat fm10k: only increment tx_timeout_count in Tx hang path fm10k: remove extraneous "Reset interface" message fm10k: separate PF only stats so that VF does not display them fm10k: use hw->mac.max_queues for stats fm10k: only show actual queues, not the maximum in hardware fm10k: allow creation of VLAN on default vid fm10k: fix unused warnings ...
2015-04-08brcmsmac: Move each system tracepoints to their own headerSteven Rostedt (Red Hat)4-220/+305
Every tracing file must have its own TRACE_SYSTEM defined. The brcmsmac tracepoint header broke this and added in the middle of the file: #undef TRACE_SYSTEM #define TRACE_SYSTEM brcmsmac #undef TRACE_SYSTEM #define TRACE_SYSTEM brcmsmac_tx #undef TRACE_SYSTEM #define TRACE_SYSTEM brcmsmac_msg Unfortunately, this broke new code in the ftrace infrastructure. Moving each of these TRACE_SYSTEMs into their own trace file with just one TRACE_SYSTEM per file fixes the issue.

2014-12-15brcmsmac: don't leak kernel memory via printk()Brian Norris1-1/+1
Debug code prints the fifo name via custom dev_warn() wrappers. The fifo_names array is only non-zero when debugging is manually enabled, which is all well and good. However, it's *not* good that this array uses zero-length arrays in the non-debug case, and so it doesn't actually have any memory allocated to it. This means that as far as we know, fifo_names[i] actually points to garbage memory. I've seen this in my log: [ 4601.205511] brcmsmac bcma0:1: wl0: brcms_c_d11hdrs_mac80211: �GeL txop exceeded phylen 137/256 dur 1602/1504 So let's give this array space enough to fill it with a NULL byte.

John W. Linville says: ==================== pull request: wireless-next 2014-07-25 Please pull this batch of updates intended for the 3.17 stream! For the mac80211 bits, Johannes says: "We have a lot of TDLS patches, among them a fix that should make hwsim tests happy again. The rest, this time, is mostly small fixes." For the Bluetooth bits, Gustavo says: "Some more patches for 3.17. The most important change here is the move of the 6lowpan code to net/6lowpan. It has been agreed with Davem that this change will go through the bluetooth tree. The rest are mostly clean up and fixes." and, "Here follows some more patches for 3.17. These are mostly fixes to what we've sent to you before for next merge window." For the iwlwifi bits, Emmanuel says: "I have the usual amount of BT Coex stuff. Arik continues to work on TDLS and Ariej contributes a few things for HS2.0. I added a few more things to the firmware debugging infrastructure. Eran fixes a small bug - pretty normal content." And for the Atheros bits, Kalle says: "For ath6kl me and Jessica added support for ar6004 hw3.0, our latest version of ar6004. For ath10k Janusz added a printout so that it's easier to check what ath10k kconfig options are enabled. He also added a debugfs file to configure maximum amsdu and ampdu values. Also we had few fixes as usual." On top of that is the usual large batch of various driver updates -- brcmfmac, mwifiex, the TI drivers, and wil6210 all get some action. Rafał has also been very busy with b43 and related updates. Also, I pulled the wireless tree into this in order to resolve a merge conflict... P.S. The change to fs/compat_ioctl.c reflects a name change in a Bluetooth header file... ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

2013-09-24brcm80211: Remove extern from function prototypesJoe Perches14-612/+535
There are a mix of function prototypes with and without extern in the kernel sources. Standardize on not using extern for function prototypes. Function prototypes don't need to be written with extern. extern is assumed by the compiler. Its use is as unnecessary as using auto to declare automatic/local variables in a block.

Pull networking changes from David Miller: "Noteworthy changes this time around: 1) Multicast rejoin support for team driver, from Jiri Pirko. 2) Centralize and simplify TCP RTT measurement handling in order to reduce the impact of bad RTO seeding from SYN/ACKs. Also, when both timestamps and local RTT measurements are available prefer the later because there are broken middleware devices which scramble the timestamp. From Yuchung Cheng. 3) Add TCP_NOTSENT_LOWAT socket option to limit the amount of kernel memory consumed to queue up unsend user data. From Eric Dumazet. 4) Add a "physical port ID" abstraction for network devices, from Jiri Pirko. 5) Add a "suppress" operation to influence fib_rules lookups, from Stefan Tomanek. 6) Add a networking development FAQ, from Paul Gortmaker. 7) Extend the information provided by tcp_probe and add ipv6 support, from Daniel Borkmann. 8) Use RCU locking more extensively in openvswitch data paths, from Pravin B Shelar. 9) Add SCTP support to openvswitch, from Joe Stringer. 10) Add EF10 chip support to SFC driver, from Ben Hutchings. 11) Add new SYNPROXY netfilter target, from Patrick McHardy. 12) Compute a rate approximation for sending in TCP sockets, and use this to more intelligently coalesce TSO frames. Furthermore, add a new packet scheduler which takes advantage of this estimate when available. From Eric Dumazet. 13) Allow AF_PACKET fanouts with random selection, from Daniel Borkmann. 14) Add ipv6 support to vxlan driver, from Cong Wang" Resolved conflicts as per discussion. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-next: (1218 commits) openvswitch: Fix alignment of struct sw_flow_key. netfilter: Fix build errors with xt_socket.c tcp: Add missing braces to do_tcp_setsockopt caif: Add missing braces to multiline if in cfctrl_linkup_request bnx2x: Add missing braces in bnx2x:bnx2x_link_initialize vxlan: Fix kernel panic on device delete. net: mvneta: implement ->ndo_do_ioctl() to support PHY ioctls net: mvneta: properly disable HW PHY polling and ensure adjust_link() works icplus: Use netif_running to determine device state ethernet/arc/arc_emac: Fix huge delays in large file copies tuntap: orphan frags before trying to set tx timestamp tuntap: purge socket error queue on detach qlcnic: use standard NAPI weights ipv6:introduce function to find route for redirect bnx2x: VF RSS support - VF side bnx2x: VF RSS support - PF side vxlan: Notify drivers for listening UDP port changes net: usbnet: update addr_assign_type if appropriate driver/net: enic: update enic maintainers and driver driver/net: enic: Exposing symbols for Cisco's low latency driver ...
