2015-06-02rtlwifi: rtl8192cu: Fix kernel deadlockLarry Finger1-1/+1
commit 414b7e3b9ce8b0577f613e656fdbc36b34b444dd upstream. The USB mini-driver in rtlwifi, which is used by rtl8192cu, issues a call to usb_control_msg() with a timeout value of 0. In some instances where the interface is shutting down, this infinite wait results in a CPU deadlock. A one second timeout fixes this problem without affecting any normal operations. This bug is reported at https://bugzilla.novell.com/show_bug.cgi?id=927786.

2014-06-18rtlwifi: rtl8192se: Fix regression due to commit 1bf4bbbLarry Finger1-0/+6
commit 5f9186990ec4579ee5b7a99b3254c29eda479f36 upstream. Beginning with kernel 3.13, this driver fails on some systems. The problem was bisected to: Commit 1bf4bbb4024dcdab5e57634dd8ae1072d42a53ac Author: Felix Fietkau <nbd@openwrt.org> Title: mac80211: send control port protocol frames to the VO queue There is noting wrong with the above commit. The regression occurs because V0 queue on RTL8192SE cards uses priority 6, not the usual 7. The fix is to modify the rtl8192se routine that sets the correct transmit queue.

[Q]-0 (stream=0, delta=15903, new_hw_ptr=293408, old_hw_ptr=277505) The exact code flow that causes that is: 1. wpa_supplicant send a start_scan request to the nl80211 driver 2. mac80211 module call rtl_op_config with IEEE80211_CONF_CHANGE_IDLE 3. rtl_ips_nic_on is called which disable local irqs 4. rtl92c_phy_set_rf_power_state() is called 5. rtl_ps_enable_nic() is called and hw_init()is executed and then the interrupts on the device are enabled A good solution could be to refactor the code to avoid calling rtl92ce_hw_init() with the irqs disabled but a quick and dirty solution that has proven to work is to reenable the irqs during the function rtl92ce_hw_init(). I think that it is safe doing so since the device interrupt will only be enabled after the init function succeed.

commit 2e8c5e56b307271c2dab6f8bfd1d8a3822ca2390 upstream. rtl_ps_enable_nic() is called from loops that will loop until this function returns true or a maximum number of retries is performed. hw_init() returns non-zero on error.

commit eafbdde9c5629bea58df07275c5917eb42afbbe7 upstream. This driver uses a number of macros to get and set various fields in the RX and TX descriptors. To work correctly, a u8 pointer to the descriptor must be used; however, in some cases a descriptor structure pointer is used instead. In addition, a duplicated statement is removed.

commit 3aef7dde8dcf09e0124f0a2665845a507331972b upstream. There is a typo in the struct member name on assignment when checking rtlphy->current_chan_bw == HT_CHANNEL_WIDTH_20_40, the check uses pwrgroup_ht40 for bound limit and uses pwrgroup_ht20 when assigning instead.

2013-12-04rtlwifi: Fix endian error in extracting packet typeMark Cave-Ayland2-57/+42
commit 0c5d63f0ab6728f05ddefa25aff55e31297f95e6 upstream. All of the rtlwifi drivers have an error in the routine that tests if the data is "special". If it is, the subsequant transmission will be at the lowest rate to enhance reliability. The 16-bit quantity is big-endian, but was being extracted in native CPU mode. One of the effects of this bug is to inhibit association under some conditions as the TX rate is too high. Based on suggestions by Joe Perches, the entire routine is rewritten. One of the local headers contained duplicates of some of the ETH_P_XXX definitions. These are deleted.

2013-07-19rtlwifi: Fix build errors for unusual casesLarry Finger10-35/+91
The present build configuration for the rtlwifi family of drivers will fail under two known conditions: (1) If rtlwifi is selected without selecting any of the dependent drivers, there are errors in the build. (2) If the PCI drivers are built into the kernel and the USB drivers are modules, or vice versa, there are missing globals. The first condition is fixed by never building rtlwifi unless at least one of the device drivers is selected. The second failure is fixed by splitting the PCI and USB codes out of rtlwifi, and creating their own mini drivers. If the drivers that use them are modules, they will also be modules. Although a number of files are touched by this patch, only Makefile and Kconfig have undergone significant changes. The only modifications to the other files were to export entry points needed by the new rtl_pci and rtl_usb units, or to rename two variables that had names that were likely to cause namespace collisions.

Commit a269913c5 entitled "rtlwifi: Rework rtl_lps_leave() and rtl_lps_enter() to use work queue" has two bugs for USB drivers. Firstly, the work queue in question was not initialized. Secondly, the callback routine used by this queue is contained within the file used for PCI devices. As a result, it is not available for architectures without PCI hardware.

Pull networking updates from David Miller: "This is a re-do of the net-next pull request for the current merge window. The only difference from the one I made the other day is that this has Eliezer's interface renames and the timeout handling changes made based upon your feedback, as well as a few bug fixes that have trickeled in. Highlights: 1) Low latency device polling, eliminating the cost of interrupt handling and context switches. Allows direct polling of a network device from socket operations, such as recvmsg() and poll(). Currently ixgbe, mlx4, and bnx2x support this feature. Full high level description, performance numbers, and design in commit 0a4db187a999 ("Merge branch 'll_poll'") From Eliezer Tamir. 2) With the routing cache removed, ip_check_mc_rcu() gets exercised more than ever before in the case where we have lots of multicast addresses. Use a hash table instead of a simple linked list, from Eric Dumazet. 3) Add driver for Atheros CQA98xx 802.11ac wireless devices, from Bartosz Markowski, Janusz Dziedzic, Kalle Valo, Marek Kwaczynski, Marek Puzyniak, Michal Kazior, and Sujith Manoharan. 4) Support reporting the TUN device persist flag to userspace, from Pavel Emelyanov. 5) Allow controlling network device VF link state using netlink, from Rony Efraim. 6) Support GRE tunneling in openvswitch, from Pravin B Shelar. 7) Adjust SOCK_MIN_RCVBUF and SOCK_MIN_SNDBUF for modern times, from Daniel Borkmann and Eric Dumazet. 8) Allow controlling of TCP quickack behavior on a per-route basis, from Cong Wang. 9) Several bug fixes and improvements to vxlan from Stephen Hemminger, Pravin B Shelar, and Mike Rapoport. In particular, support receiving on multiple UDP ports. 10) Major cleanups, particular in the area of debugging and cookie lifetime handline, to the SCTP protocol code. From Daniel Borkmann. 11) Allow packets to cross network namespaces when traversing tunnel devices. From Nicolas Dichtel. 12) Allow monitoring netlink traffic via AF_PACKET sockets, in a manner akin to how we monitor real network traffic via ptype_all. From Daniel Borkmann. 13) Several bug fixes and improvements for the new alx device driver, from Johannes Berg. 14) Fix scalability issues in the netem packet scheduler's time queue, by using an rbtree. From Eric Dumazet. 15) Several bug fixes in TCP loss recovery handling, from Yuchung Cheng. 16) Add support for GSO segmentation of MPLS packets, from Simon Horman. 17) Make network notifiers have a real data type for the opaque pointer that's passed into them. Use this to properly handle network device flag changes in arp_netdev_event(). From Jiri Pirko and Timo Teräs. 18) Convert several drivers over to module_pci_driver(), from Peter Huewe. 19) tcp_fixup_rcvbuf() can loop 500 times over loopback, just use a O(1) calculation instead. From Eric Dumazet. 20) Support setting of explicit tunnel peer addresses in ipv6, just like ipv4. From Nicolas Dichtel. 21) Protect x86 BPF JIT against spraying attacks, from Eric Dumazet. 22) Prevent a single high rate flow from overruning an individual cpu during RX packet processing via selective flow shedding. From Willem de Bruijn. 23) Don't use spinlocks in TCP md5 signing fast paths, from Eric Dumazet. 24) Don't just drop GSO packets which are above the TBF scheduler's burst limit, chop them up so they are in-bounds instead. Also from Eric Dumazet. 25) VLAN offloads are missed when configured on top of a bridge, fix from Vlad Yasevich. 26) Support IPV6 in ping sockets. From Lorenzo Colitti. 27) Receive flow steering targets should be updated at poll() time too, from David Majnemer. 28) Fix several corner case regressions in PMTU/redirect handling due to the routing cache removal, from Timo Teräs. 29) We have to be mindful of ipv4 mapped ipv6 sockets in upd_v6_push_pending_frames(). From Hannes Frederic Sowa. 30) Fix L2TP sequence number handling bugs, from James Chapman." * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-next: (1214 commits) drivers/net: caif: fix wrong rtnl_is_locked() usage drivers/net: enic: release rtnl_lock on error-path vhost-net: fix use-after-free in vhost_net_flush net: mv643xx_eth: do not use port number as platform device id net: sctp: confirm route during forward progress virtio_net: fix race in RX VQ processing virtio: support unlocked queue poll net/cadence/macb: fix bug/typo in extracting gem_irq_read_clear bit Documentation: Fix references to defunct linux-net@vger.kernel.org net/fs: change busy poll time accounting net: rename low latency sockets functions to busy poll bridge: fix some kernel warning in multicast timer sfc: Fix memory leak when discarding scattered packets sit: fix tunnel update via netlink dt:net:stmmac: Add dt specific phy reset callback support. dt:net:stmmac: Add support to dwmac version 3.610 and 3.710 dt:net:stmmac: Allocate platform data only if its NULL. net:stmmac: fix memleak in the open method ipv6: rt6_check_neigh should successfully verify neigh if no NUD information are available net: ipv6: fix wrong ping_v6_sendmsg return value ...

For the workqueue creation interfaces that do not expect format strings, make sure they cannot accidently be parsed that way. Additionally, clean up calls made with a single parameter that would be handled as a format string. Many callers are passing potentially dynamic string content, so use "%s" in those cases to avoid any potential accidents.
