2014-01-07mac80211: remove channel_change_timeJohannes Berg
This value is no longer used by mac80211, and practically no driver ever set it to a correct value anyway, so remove it. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2014-01-03rtlwifi: use ether_addr_equal_64bitsJulia Lawall
Ether_addr_equal_64bits is more efficient than ether_addr_equal, and can be used when each argument is an array within a structure that contains at least two bytes of data beyond the array. The structures involved are: ieee80211_hdr defined in include/linux/ieee80211.h and rtl_mac defined in drivers/net/wireless/rtlwifi/wifi.h This was done using Coccinelle (http://coccinelle.lip6.fr/).

2013-11-11rtlwifi: Fix endian error in extracting packet typeMark Cave-Ayland
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.

2013-07-18rtlwifi: Fix build errors for unusual casesLarry Finger
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.

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.

Many callers are passing potentially dynamic string content, so use "%s" in those cases to avoid any potential accidents.

2013-02-15mac80211: stop toggling IEEE80211_HT_CAP_SUP_WIDTH_20_40Johannes Berg
For VHT, many more bandwidth changes are possible. As a first step, stop toggling the IEEE80211_HT_CAP_SUP_WIDTH_20_40 flag in the HT capabilities and instead introduce a bandwidth field indicating the currently usable bandwidth to transmit to the station. Of course, make all drivers use it. To achieve this, make ieee80211_ht_cap_ie_to_sta_ht_cap() get the station as an argument, rather than the new capabilities, so it can set up the new bandwidth field. If the station is a VHT station and VHT bandwidth is in use, also set the bandwidth accordingly. Doing this allows us to get rid of the supports_40mhz flag as the HT capabilities now reflect the true capability instead of the current setting. While at it, also fix ieee80211_ht_cap_ie_to_sta_ht_cap() to not ignore HT cap overrides when MCS TX isn't supported (not that it really happens...)

2013-02-04rtlwifi: Fix scheduling while atomic bugLarry Finger
Kernel commits 41affd5 and 6539306 changed the locking in rtl_lps_leave() from a spinlock to a mutex by doing the calls indirectly from a work queue to reduce the time that interrupts were disabled. This change was fine for most systems; however a scheduling while atomic bug was reported in https://bugzilla.redhat.com/show_bug.cgi?id=903881. The backtrace indicates that routine rtl_is_special(), which calls rtl_lps_leave() in three places was entered in atomic context. These direct calls are replaced by putting a request on the appropriate work queue.

2012-01-30rtlwifi: Convert to asynchronous firmware loadLarry Finger
This patch addresses a kernel bugzilla report and two recent mail threads. The kernel bugzilla report is https://bugzilla.kernel.org/show_bug.cgi?id=42632, which reports a udev timeout on boot. The first mail thread, which was on LKML (http://lkml.indiana.edu/hypermail/ linux/kernel/1112.3/00965.html) was for a WARNING that occurs after a suspend/resume cycle for rtl8192cu. The scond mail thread (http://marc.info/?l=linux-wireless&m=132655490826766&w=2) concerned changes in udev that break drivers that delay while firmware is loaded on modprobe. This patch converts all rtlwifi-based drivers to use the asynchronous firmware loading mechanism. Drivers rtl8192ce, rtl8192cu and rtl8192de share a common callback routine. Driver rtl8192se needs different handling of the firmware, thus it has its own code. Signed-off-by: Larry Finger <Larry.Finger@lwfinger.net> Cc: Stable <stable@vger.kernel.org> Signed-off-by: John W.

2011-12-13rtlwifi: merge ips,lps spinlocks into one mutexStanislaw Gruszka
With previous patch "rtlwifi: use work for lps" we can now use mutex for protecting ps mode changing critical sections. This fixes running system with interrupts disabled for long time. Merge ips_lock and lps_lock as they seems to protect the same data structures (accessed in rtl_ps_set_rf_state() function).

2011-11-21rtlwifi: rtl8192cu: Fix endianian issuesLarry Finger
Driver rtlwifi fails on a big-endian host. These changes have been tested on a Mac PowerBook G4, which has a PPC processor. Although this patch touches some of the code that will affect endian issues on PCI hardware through drivers rtl8192ce, rtl8192se, and rtl8192de, these have not been tested due to lack of suitable hardware.
