2013-06-20RDMA/cma: Restrict AF_IB loopback to binding to IB devices onlySean Hefty
If a user specifies AF_IB as the source address for a loopback connection, limit the resolution to IB devices only. Signed-off-by: Sean Hefty <sean.hefty@intel.com> Signed-off-by: Roland Dreier <roland@purestorage.com>
2013-06-20RDMA/cma: Add helper functions to return id address informationSean Hefty
Provide inline helpers to extract source and destination address data from the rdma_cm_id. Signed-off-by: Sean Hefty <sean.hefty@intel.com> Signed-off-by: Roland Dreier <roland@purestorage.com>
2013-06-20RDMA/cma: Do not modify sa_family when setting loopback addressSean Hefty
cma_resolve_loopback is called after an rdma_cm_id has been bound to a specific sa_family and port. Once the source sa_family for the id has been set, do not modify it. Only the actual IP address portion of the source address needs to be set. As part of this fix, we can simplify setting the source address by moving the loopback address assignment from cma_resolve_loopback to cma_bind_loopback. cma_bind_loopback is only invoked when the source address is the loopback address. Finally, add loopback support for AF_IB as part of the change. Signed-off-by: Sean Hefty <sean.hefty@intel.com> Signed-off-by: Roland Dreier <roland@purestorage.com>
2013-06-20RDMA/cma: Allow user to specify AF_IB when bindingSean Hefty
Modify rdma_bind_addr to allow the user to specify AF_IB when binding to a device. AF_IB indicates that the user is not mapping an IP address to the native IB addressing. (The mapping may have already been done, or is not needed) Signed-off-by: Sean Hefty <sean.hefty@intel.com> Signed-off-by: Roland Dreier <roland@purestorage.com>
2013-06-20RDMA/cma: Update port reservation to support AF_IBSean Hefty
The AF_IB uses a 64-bit service id (SID), which the user can control through the use of a mask. The rdma_cm will assign values to the unmasked portions of the SID based on the selected port space and port number. Because the IB spec divides the SID range into several regions, a SID/mask combination may fall into one of the existing port space ranges as defined by the RDMA CM IP Annex. Map the AF_IB SID to the correct RDMA port space. Signed-off-by: Sean Hefty <sean.hefty@intel.com> Signed-off-by: Roland Dreier <roland@purestorage.com>
2013-06-20IB/addr: Add AF_IB support to ip_addr_sizeSean Hefty
Add support for AF_IB to ip_addr_size, and rename the function to account for the change. Give the compiler more control over whether the call should be inline or not by moving the definition into the .c file, removing the static inline, and exporting it.

2013-06-20RDMA/cma: Allow enabling reuseaddr in any stateSean Hefty
The rdma_cm only allows setting reuseaddr if the corresponding rdma_cm_id is in the idle state. Allow setting this value in other states. This brings the behavior more inline with sockets. Signed-off-by: Sean Hefty <sean.hefty@intel.com> Signed-off-by: Roland Dreier <roland@purestorage.com>

ETRAX_ETHERNET selects ETHERNET and MII, which depend on NETDEVICES. I don't think anything should select NETDEVICES, so make it a dependency. It also doesn't need to select or depend on ETHERNET, which has nothing to do with the Ethernet library functions. BPCTL selects MII, which depends on NETDEVICES.

Conflicts: drivers/net/wireless/ath/ath9k/Kconfig drivers/net/xen-netback/netback.c net/batman-adv/bat_iv_ogm.c net/wireless/nl80211.c The ath9k Kconfig conflict was a change of a Kconfig option name right next to the deletion of another option. The xen-netback conflict was overlapping changes involving the handling of the notify list in xen_netbk_rx_action(). Batman conflict resolution provided by Antonio Quartulli, basically keep everything in both conflict hunks. The nl80211 conflict is a little more involved. In 'net' we added a dynamic memory allocation to nl80211_dump_wiphy() to fix a race that Linus reported. Meanwhile in 'net-next' the handlers were converted to use pre and post doit handlers which use a flag to determine whether to hold the RTNL mutex around the operation. However, the dump handlers to not use this logic. Instead they have to explicitly do the locking. There were apparent bugs in the conversion of nl80211_dump_wiphy() in that we were not dropping the RTNL mutex in all the return paths, and it seems we very much should be doing so. So I fixed that whilst handling the overlapping changes. To simplify the initial returns, I take the RTNL mutex after we try to allocate 'tb'. Signed-off-by: David S. Miller <davem@davemloft.net>

git://git.kernel.org/pub/scm/linux/kernel/git/linville/wireless into wireless John W. Linville says: ==================== This will probably be the last batch of wireless fixes intended for 3.10. Many of these are one- or two-liners, and a couple of others are mostly relocating existing code to avoid races or to limit the code to effecting specific hardware, etc. The mac80211 fixes have a couple of exceptions to the above. Regarding those, Johannes says: "Following davem's complaint about my patch, here's a new pull request w/o the patch he was complaining about, but instead with the const fix rolled into the fix. I have a fix for radar detection, one for rate control and a workaround for broken HT APs which is a regression fix because we didn't rely on them to be correct before." Johannes also sends some iwlwifi fixes: "I picked up Nikolay's patch for the chain noise calibration bug that seems to have been there forever, a fix from Emmanuel for setting TX flags on BAR frames and a fix of my own to avoid printing request_module() errors if the kernel isn't even modular. We also have our own version of Stanislaw's fix for rate control." Along with those... Anderson Lizardo fixes a Bluetooth memory corruption bug when an MTU value is set to too small of a value. Arend van Spriel sends a revised brcmsmac bug that fixes a regression caused by a bad return value in an earlier patch. He also sends a brcmfmac fix to avoid an oops when loading the driver at boot. Daniel Drake fixes a race condition in btmrvl that causes hangs on suspend for OLPC hardware. Johan Hedberg adds a check to avoid sending a HCI_Delete_Stored_Link_Key command to devices that don't support them, avoiding some scary looking log spam. Stanislaw Gruszka gives us a fix for iwlegacy to be able to use rates higher than 1Mb/s on older wireless networks. He also sends an rt2x00 fix to reinstate older tx power handling behavior for some devices that didn't work well with the current code. ==================== Signed-off-by: David S.

2013-06-17alx: add a simple AR816x/AR817x device driverJohannes Berg
This is a very simple driver, based on the original vendor driver that Qualcomm/Atheros published/submitted previously, but reworked to make the code saner. However, it also lost a number of features (TSO/GSO, VLAN acceleration and multi- queue support) in the process, as well as debugging support features I didn't have any use for. The only thing I left is checksum offload. More features can obviously be added, but this seemed like a good start for having a driver in mainline at all.

2013-06-17tg3: Prevent system hang during repeated EEH errors.Michael Chan
The current tg3 code assumes the pci_error_handlers to be always called in sequence. In particular, during ->error_detected(), NAPI is disabled and the device is shutdown. The device is later reset and NAPI re-enabled in ->slot_reset() and ->resume(). In EEH, if more than 6 errors are detected in a hour, only ->error_detected() will be called. This will leave the driver in an inconsistent state as NAPI is disabled but netif_running state is still true. When the device is later closed, we'll try to disable NAPI again and it will loop forever. We fix this by closing the device if we encounter any error conditions during the normal sequence of the pci_error_handlers. v2: Remove the changes in tg3_io_resume() based on Benjamin Poirier's feedback.

Pull networking fixes from David Miller: 1) Fix RTNL locking in batman-adv, from Matthias Schiffer. 2) Don't allow non-passthrough macvlan devices to set NOPROMISC via netlink, otherwise we can end up with corrupted promisc counter values on the device. From Michael S Tsirkin. 3) Fix stmmac driver build with debugging defines enabled, from Dinh Nguyen. 4) Make sure name string we give in socket address in AF_PACKET is NULL terminated, from Daniel Borkmann. 5) Fix leaking of two uninitialized bytes of memory to userspace in l2tp, from Guillaume Nault. 6) Clear IPCB(skb) before tunneling otherwise we touch dangling IP options state and crash. From Saurabh Mohan. 7) Fix suspend/resume for davinci_mdio by using suspend_late and resume_early. From Mugunthan V N. 8) Don't tag ip_tunnel_init_net and ip_tunnel_delete_net with __net_{init,exit}, they can be called outside of those contexts. From Eric Dumazet. 9) Fix RX length error in sh_eth driver, from Yoshihiro Shimoda. 10) Fix missing sctp_outq initialization in some code paths of SCTP stack, from Neil Horman. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net: (21 commits) sctp: fully initialize sctp_outq in sctp_outq_init netiucv: Hold rtnl between name allocation and device registration. tulip: Properly check dma mapping result net: sh_eth: fix incorrect RX length error if R8A7740 ip_tunnel: remove __net_init/exit from exported functions drivers: net: davinci_mdio: restore mdio clk divider in mdio resume drivers: net: davinci_mdio: moving mdio resume earlier than cpsw ethernet driver net/ipv4: ip_vti clear skb cb before tunneling. tg3: Wait for boot code to finish after power on l2tp: Fix sendmsg() return value l2tp: Fix PPP header erasure and memory leak bonding: fix igmp_retrans type and two related races bonding: reset master mac on first enslave failure packet: packet_getname_spkt: make sure string is always 0-terminated net: ethernet: stmicro: stmmac: Fix compile error when STMMAC_XMIT_DEBUG used be2net: Fix 32-bit DMA Mask handling xen-netback: don't de-reference vif pointer after having called xenvif_put() macvlan: don't touch promisc without passthrough batman-adv: Don't handle address updates when bla is disabled batman-adv: forward late OGMs from best next hop ...
