| | * | | ath6kl: Fix 4-way handshake failure in AP and P2P GO modeVasanthakumar Thiagarajan2012-04-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | RSN capability field of RSN IE which is generated (which is what really advertised in beacon/probe response) differs from the one generated in wpa_supplicant. This inconsistency in rsn IE results in 4-way handshake failure. To fix this, configure rsn capability used in wpa_supplicant in firmware using a new wmi command, WMI_SET_IE_CMDID. There is a bit (ATH6KL_FW_CAPABILITY_RSN_CAP_OVERRIDE) in fw_capabilities to advertise this support to driver.

| | * | | ath6kl: Configure htcap in fw based on the channel type in AP modeVasanthakumar Thiagarajan2012-04-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch disables HT in start_ap if the type of the channel on which the AP mode is going to be operating is non-HT. HT is enabled with default ht cap setting if the operating channel is going to be 11n.

This is because interface 0 is always initialized to non-p2p operations. Fix this issue by initializing all the interfaces for p2p when fw is capable of dynamic interface switching. When fw is not capable of dynamic switching, make sure p2p is not brought up on interface which is not initialized for this purpose.

| | * | | ath6kl: Store scan request info in-advance before sending SCAN requestRaja Mani2012-03-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In current code, Scan request info is recorded in vif->scan_req after sending SCAN request to the firmware in ath6kl_cfg80211_scan(). In some corner cases, firmware sends SCAN_COMPLETE event immediately when it receives SCAN request, which internally executes scan complete event handler ath6kl_cfg80211_scan_complete_event() first. So, Scan completion handler will a get a chance to executed even before storing scan request info in ath6kl_cfg80211_scan(). Scan completion handler never report SCAN_COMPLETE event to cfg80211 if scan request info(vif->scan_req) is NULL. This leads to scan failure issue ("Device or resource busy error") during next SCAN request from the user space. This patch ensures that scan request info is stored before sending SCAN request.

For GO probe response, ath6kl needs to call ath6kl_send_go_probe_resp (this will add only WSC/P2P IEs and the rest of the IEs are filled in by the firmware). That was done based on the nw_type == AP_NETWORK which would work if P2P Device role were in a separate netdev. When P2P Device and GO use the same netdev, ath6kl needs to use the special GO probe response case only if SSID is longer than P2P wildcard SSID.

As the issue was originally reported in ChromeOs with AR9382 chips, this detection logic is enabled only for AR9380/2 chips.

| * | | | ath9k_hw: improve ANI processing and rx desensitizing parametersRajkumar Manoharan2012-04-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch improves ANI operations by switching among the immunity levels based on PHY errors and beacon rssi which will adjust receiver desensitizing parameters. The changes are * Configure the Weak Signal Detection based on current immunity value. * At highest OFDM immunity level poor performance was observed with strong interference. By tuning the FIR step and spur immunity levels and not changing any weak signal detection thresholds at any level helped to improve the performance. * ANI took long time to recover back to lower immunity levels on heavy data load. As the listen time got reset to zero before reaching to the 5x of aniperiod, the immunity level is not lowering back even without any interference. This patch fix that.

I still need to send a few checkpoint/restore patches. I've been wobbly about merging them because I'm wobbly about the overall prospects for success of the project. But after speaking with Pavel at the LSF conference, it sounds like they're further toward completion than I feared - apparently davem is at the "has stopped complaining" stage regarding the net changes. So I need to go back and re-review those patchs and their (lengthy) discussion." * emailed from Andrew Morton <akpm@linux-foundation.org>: (16 patches) memcg swap: use mem_cgroup_uncharge_swap fix backlight: add driver for DA9052/53 PMIC v1 C6X: use set_current_blocked() and block_sigmask() MAINTAINERS: add entry for sparse checker MAINTAINERS: fix REMOTEPROC F: typo alpha: use set_current_blocked() and block_sigmask() simple_open: automatically convert to simple_open() scripts/coccinelle/api/simple_open.cocci: semantic patch for simple_open() libfs: add simple_open() hugetlbfs: remove unregister_filesystem() when initializing module drivers/rtc/rtc-88pm860x.c: fix rtc irq enable callback fs/xattr.c:setxattr(): improve handling of allocation failures fs/xattr.c:listxattr(): fall back to vmalloc() if kmalloc() failed fs/xattr.c: suppress page allocation failure warnings from sys_listxattr() sysrq: use SEND_SIG_FORCED instead of force_sig() proc: fix mount -t proc -o AAA

This leads to a proliferation of the default_open() implementation across the entire tree. Now that the common implementation has been consolidated into libfs we can replace all the users of this function with simple_open(). This replacement was done with the following semantic patch: <smpl> @ open @ identifier open_f != simple_open; identifier i, f; @@ -int open_f(struct inode *i, struct file *f) -{ ( -if (i->i_private) -f->private_data = i->i_private; | -f->private_data = i->i_private; ) -return 0; -} @ has_open depends on open @ identifier fops; identifier open.open_f; @@ struct file_operations fops = { ... -.open = open_f, +.open = simple_open, ... }; </smpl> [akpm@linux-foundation.org: checkpatch fixes] Signed-off-by: Stephen Boyd <sboyd@codeaurora.org> Cc: Greg Kroah-Hartman <gregkh@linuxfoundation.org> Cc: Al Viro <viro@zeniv.linux.org.uk> Cc: Julia Lawall <Julia.Lawall@lip6.fr> Acked-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
