* rt2x00: Endless loop on hub port power downRichard Genoud2014-05-221-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | I've met an endless (or at least very long) loop if I power down the usb port on witch a usb wifi key is plugged. (Ok, it's not very smart to power down a usb port when a usb key is in used... but still, I think that should not lead to an endless loop). I have a lot of: ieee80211 phy1: rt2x00usb_vendor_request: Error - Vendor Request 0x07 failed for offset 0x0438 with error -71 (-71==-EPROTO) How to reproduce: - plug an usb wifi key - ip link set wlan0 up - hub-ctrl -b usb_bus -d usb_device -P usb_port -p 0 hub-ctrl source: https://github.com/codazoda/hub-ctrl.c/blob/master/hub-ctrl.c The following patch prevents the endless loop, but I'm really not sure that The Right Way To Do It (R) Signed-off-by: Richard Genoud <richard.genoud@gmail.com> Signed-off-by: John W.

| * Revert "rt2x00: rt2800lib: Update BBP register initialization for RT53xx"Stanislaw Gruszka2014-03-131-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This reverts commit eac40d9631a7db43570df859fa8a9922e9623607. It cause random connection drops on RT5390 PCI adapters. On Mediatek there is different driver version available for RT53xx chip based on bus type (2.5.0.3 for PCI and 2.6.1.3 for USB). Hence possibly we should set registers differently based on bus type. But is also possible that new driver (i.e. 2.6.1.3) was not verified on RT53xx USB. Until we figure out how to initialize registers properly for RT53xx just revert commit eac40d9631a7db43570df859fa8a9922e9623607 since it cause regression.

* | wireless/rt2x00: don't use PREPARE_WORK in rt2800usb.cTejun Heo2014-02-241-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | PREPARE_[DELAYED_]WORK() are being phased out. They have few users and a nasty surprise in terms of reentrancy guarantee as workqueue considers work items to be different if they don't have the same work function. Update rt2800usb.c to use INIT_WORK() instead of PREPARE_WORK(). As the work item isn't in active use during rt2800usb_probe_hw(), this doesn't cause any behavior difference. It would probably be best to route this with other related updates through the workqueue tree. Only compile tested.

Some genetlink protocols we passing in constant counts for their ops array rather than something like ARRAY_SIZE(ops) or similar. Also, some genetlink protocols were using fixed IDs for their multicast groups. We have to retain these fixed IDs to keep existing userland tools working, but reserve them so that other multicast groups used by other protocols can not possibly conflict. In dealing with these two problems, we actually now use less state management for genetlink operations and multicast groups. 2) When configuring interface hardware timestamping, fix several drivers that simply do not validate that the hwtstamp_config value is one the driver actually supports. From Ben Hutchings. 3) Invalid memory references in mwifiex driver, from Amitkumar Karwar. 4) In dev_forward_skb(), set the skb->protocol in the right order relative to skb_scrub_packet(). From Alexei Starovoitov. 5) Bridge erroneously fails to use the proper wrapper functions to make calls to netdev_ops->ndo_vlan_rx_{add,kill}_vid. Fix from Toshiaki Makita. 6) When detaching a bridge port, make sure to flush all VLAN IDs to prevent them from leaking, also from Toshiaki Makita. 7) Put in a compromise for TCP Small Queues so that deep queued devices that delay TX reclaim non-trivially don't have such a performance decrease. One particularly problematic area is 802.11 AMPDU in wireless. From Eric Dumazet. 8) Fix crashes in tcp_fastopen_cache_get(), we can see NULL socket dsts here. Fix from Eric Dumzaet, reported by Dave Jones. 9) Fix use after free in ipv6 SIT driver, from Willem de Bruijn. 10) When computing mergeable buffer sizes, virtio-net fails to take the virtio-net header into account. From Michael Dalton. 11) Fix seqlock deadlock in ip4_datagram_connect() wrt. statistic bumping, this one has been with us for a while. From Eric Dumazet. 12) Fix NULL deref in the new TIPC fragmentation handling, from Erik Hugne. 13) 6lowpan bit used for traffic classification was wrong, from Jukka Rissanen. 14) macvlan has the same issue as normal vlans did wrt. propagating LRO disabling down to the real device, fix it the same way. From Michal Kubecek. 15) CPSW driver needs to soft reset all slaves during suspend, from Daniel Mack. 16) Fix small frame pacing in FQ packet scheduler, from Eric Dumazet. 17) The xen-netfront RX buffer refill timer isn't properly scheduled on partial RX allocation success, from Ma JieYue. 18) When ipv6 ping protocol support was added, the AF_INET6 protocol initialization cleanup path on failure was borked a little. Fix from Vlad Yasevich. 19) If a socket disconnects during a read/recvmsg/recvfrom/etc that blocks we can do the wrong thing with the msg_name we write back to userspace. From Hannes Frederic Sowa. There is another fix in the works from Hannes which will prevent future problems of this nature. 20) Fix route leak in VTI tunnel transmit, from Fan Du. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net: (106 commits) genetlink: make multicast groups const, prevent abuse genetlink: pass family to functions using groups genetlink: add and use genl_set_err() genetlink: remove family pointer from genl_multicast_group genetlink: remove genl_unregister_mc_group() hsr: don't call genl_unregister_mc_group() quota/genetlink: use proper genetlink multicast APIs drop_monitor/genetlink: use proper genetlink multicast APIs genetlink: only pass array to genl_register_family_with_ops() tcp: don't update snd_nxt, when a socket is switched from repair mode atm: idt77252: fix dev refcnt leak xfrm: Release dst if this dst is improper for vti tunnel netlink: fix documentation typo in netlink_set_err() be2net: Delete secondary unicast MAC addresses during be_close be2net: Fix unconditional enabling of Rx interface options net, virtio_net: replace the magic value ping: prevent NULL pointer dereference on write to msg_name bnx2x: Prevent "timeout waiting for state X" bnx2x: prevent CFC attention bnx2x: Prevent panic during DMAE timeout ...

* | kfifo API type safetyStefani Seibold2013-11-152-2/+2
|/ | | | | | | | | | | | | | | | | | | | | | | | | This patch enhances the type safety for the kfifo API. It is now safe to put const data into a non const FIFO and the API will now generate a compiler warning when reading from the fifo where the destination address is pointing to a const variable. As a side effect the kfifo_put() does now expect the value of an element instead a pointer to the element. This was suggested Russell King. It make the handling of the kfifo_put easier since there is no need to create a helper variable for getting the address of a pointer or to pass integers of different sizes. IMHO the API break is okay, since there are currently only six users of kfifo_put(). The code is also cleaner by kicking out the "if (0)" expressions.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Polling TX statuses too frequently has two negative effects. First is randomly peek CPU usage, causing overall system functioning delays. Second bad effect is that device is not able to fill TX statuses in H/W register on some workloads and we get lot of timeouts like below: ieee80211 phy4: rt2800usb_entry_txstatus_timeout: Warning - TX status timeout for entry 7 in queue 2 ieee80211 phy4: rt2800usb_entry_txstatus_timeout: Warning - TX status timeout for entry 7 in queue 2 ieee80211 phy4: rt2800usb_txdone: Warning - Got TX status for an empty queue 2, dropping This not only cause flood of messages in dmesg, but also bad throughput, since rate scaling algorithm can not work optimally. In the future, we should probably make polling interval be adjusted automatically, but for now just increase values, this make mentioned problems gone.

Create a clone of that to get rid of the dependency. Even though the two functions are using the same variable, but the SoC specific code will be moved into a separate module which will have its own 'modparam_nohwcrypt' variable.
