| | * | | ath9k: fix double-free bug on beacon generate failureFelix Fietkau2013-01-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When the next beacon is sent, the ath_buf from the previous run is reused. If getting a new beacon from mac80211 fails, bf->bf_mpdu is not reset, yet the skb is freed, leading to a double-free on the next beacon tx attempt, resulting in a system crash.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On AR9300 the rx FIFO needs to be empty during reset to ensure that no further DMA activity is generated, otherwise it might lead to memory corruption issues.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Dropping packets from aggregation sessions is usually not a good idea, as it might upset the synchronization of the BlockAck receive window of the remote node. The use of the retry_tx parameter to reset/tx-drain functions also seemed a bit arbitrary. This patch removes this parameter altogether and ensures that pending tx frames are not dropped for no good reason. Signed-off-by: Felix Fietkau <nbd@openwrt.org> Signed-off-by: John W.

AR92xx and AR93xx chips are supported for now. The spectral scan is triggered by configuring a mode through a debugfs control file. Samples can be gathered via another relay debugfs file. Essentially, to try it out: echo chanscan > /sys/kernel/debug/ieee80211/phy0/ath9k/spectral_scan_ctl iw dev wlan0 scan cat /sys/kernel/debug/ieee80211/phy0/ath9k/spectral_scan0 > samples echo disable > /sys/kernel/debug/ieee80211/phy0/ath9k/spectral_scan_ctl This feature is still experimental. The special "chanscan" mode is used to perform spectral scan while mac80211 is scanning for channels. To allow this, sw_scan_start/complete() ops have been added. The patch contains code snippets and information from Zefir Kurtisi and information provided by Adrian Chadd and Felix Fietkau.

Split these different cases so that the driver can act accordingly; however, treat local and remote stop the same way and ask the driver to not send frames as aggregated packets any more.

| * | | carl9170: fix -EINVAL bailout during init with !CONFIG_MAC80211_MESHChristian Lamparter2013-01-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Sean reported that as of 3.7, his AR9170 device no longer works because the driver fails during initialization. He noted this is due to: "In carl9170/fw.c, ar->hw->wiphy is tagged with NL80211_IFTYPE_MESH_POINT support if the firmware has Content after Beacon Queuing. This is both in interface_modes and the only iface_combinations entry. If CONFIG_MAC80211_MESH is not set, ieee80211_register_hw removes NL80211_IFTYPE_MESH_POINT from interface_modes, but not iface_combinations. wiphy_register then checks to see if every interface type in every interface combination is in interface_modes. NL80211_IFTYPE_MESH_POINT was removed, so you get a WARN_ON warning and it returns -EINVAL, giving up." Unfortunately, the iface_combination (types) feature bitmap in ieee80211_iface_limit is part of a const member in the ieee80211_iface_combination struct. Hence, the MESH_POINT feature flag can't be masked by wiphy_register in the same way as interface_modes in ieee80211_register_hw.

| |/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since ath9k makes use of mac80211's debugfs hooks to maintain station statistics, make ATH9K_DEBUGFS select MAC80211_DEBUGFS.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Use the standard #defines for PCIe Capability ASPM fields. Previously we used PCIE_LINK_STATE_L0S and PCIE_LINK_STATE_L1 directly, but these are defined for the Linux ASPM interfaces, e.g., pci_disable_link_state(), and only coincidentally match the actual register bits. PCIE_LINK_STATE_CLKPM, also part of that interface, does not match the register bit. Signed-off-by: Bjorn Helgaas <bhelgaas@google.com>
