2013-02-08NFC: llcp: integer underflow in nfc_llcp_set_remote_gb()Dan Carpenter1-3/+2
If gb_len is less than 3 it would cause an integer underflow and possibly memory corruption in nfc_llcp_parse_gb_tlv(). I removed the old test for gb_len == 0. I also removed the test for ->remote_gb == NULL. It's not possible for ->remote_gb to be NULL and we have already dereferenced ->remote_gb_len so it's too late to test.

2013-02-08wlcore: fix wrong remote rates when starting STA roleLuciano Coelho1-3/+5
In wl18xx, we use a new ACX command in order to set the remote supported rates, once we know it (ie. after association). The wl12xx firmware doesn't support changing the rates after the STA is started, so we need to use all supported rates. Commit 530abe19 (wlcore: add ACX_PEER_CAP command) broke that by using wlvif->rate_set when starting the STA role. Signed-off-by: Luciano Coelho <[email protected]>

The platform data is used not only by wlcore-based drivers, but also by wl1251. Move it up in the directory hierarchy to reflect this. Additionally, make it truly optional. At the moment, disabling platform data while wl1251_sdio or wlcore_sdio are enabled doesn't work, but it will be necessary when device tree support is implemented.

We can't pass pointers from the platform data to the modules, because with DT it cannot be done. Those pointers are not set by the board files anyway. It's the bus modules that set them, so they can be safely removed from the platform data without changing any board files. Create a new structure that the bus modules pass to wlcore.

2013-02-05iwlwifi: use threaded interrupt handlerJohannes Berg11-52/+85
With new transports coming up, move to threaded interrupt handling now. This has the advantage that we can use the same locking scheme with all different transports we may need to implement. Note that the TX path obviously still runs in a tasklet, so some spin_lock() calls need to change to spin_lock_bh() calls to properly lock out the TX path. In my test on a Calpella platform this has no impact on throughput or latency. Also add lockdep annotations to avoid lockups due to catch sending synchronous commands or using locks that connect with them from the irq thread.

2013-02-04brcmsmac: rework of mac80211 .flush() callback operationArend van Spriel4-29/+27
This patch addresses a long standing issue of the driver with the mac80211 .flush() callback. Since implementing the .flush() callback a number of issues have been fixed, but a WARN_ON_ONCE() was still triggered because the timeout on the flush could still occur. This patch changes the awkward design using msleep() into one using a waitqueue. The waiting flush() context will kick the transmit dma when it is idle and the timeout used waiting for the event is set to 500 ms. Worst case there can be 64 frames outstanding for transmit in the driver. At a rate of 1Mbps that would take 1.5 seconds assuming MTU is 1500 bytes and ignoring retries. The WARN_ON_ONCE() is also removed as this was put in to indicate the flush timeout as a reason for the driver to stall. That was not happening since fixing endless AMPDU retries with following upstream commit: commit 85091fc0a75653e239dc8379658515e577544927 Author: Arend van Spriel <[email protected]> Date: Thu Feb 23 18:38:22 2012 +0100 brcm80211: smac: fix endless retry of A-MPDU transmissions bugzilla: 42840 <https://bugzilla.kernel.org/show_bug.cgi?id=42840> bugzilla@redhat: <https://bugzilla.redhat.com/show_bug.cgi?id=799168> bugzilla@redhat: <https://bugzilla.redhat.com/show_bug.cgi?id=787649> Cc: Jonathan Nieder <[email protected]> Cc: Stanislaw Gruszka <[email protected]> Cc: Camaleón <[email protected]> Cc: Milan Bouchet-Valat <[email protected]> Cc: Seth Forshee <[email protected]> Reviewed-by: Pieter-Paul Giesberts <[email protected]> Reviewed-by: Hante Meuleman <[email protected]> Reviewed-by: Piotr Haber <[email protected]> Signed-off-by: Arend van Spriel <[email protected]> Acked-by: Seth Forshee <[email protected]> Signed-off-by: John W.

2013-02-04rtlwifi: Fix scheduling while atomic bugLarry Finger1-3/+4
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.

2013-02-04mac80211: mesh power save basicsMarco Porsch21-17/+811
Add routines to - maintain a PS mode for each peer and a non-peer PS mode - indicate own PS mode in transmitted frames - track neighbor STAs power modes - buffer frames when neighbors are in PS mode - add TIM and Awake Window IE to beacons - release frames in Mesh Peer Service Periods Add local_pm to sta_info to represent the link-specific power mode at this station towards the remote station. When a peer link is established, use the default power mode stored in mesh config. Update the PS status if the peering status of a neighbor changes. Maintain a mesh power mode for non-peer mesh STAs. Set the non-peer power mode to active mode during peering. Authenticated mesh peering is currently not working when either node is configured to be in power save mode. Indicate the current power mode in transmitted frames. Use QoS Nulls to indicate mesh power mode transitions. For performance reasons, calls to the function setting the frame flags are placed in HWMP routing routines, as there the STA pointer is already available. Add peer_pm to sta_info to represent the peer's link-specific power mode towards the local station. Add nonpeer_pm to represent the peer's power mode towards all non-peer stations. Track power modes based on received frames. Add the ps_data structure to ieee80211_if_mesh (for TIM map, PS neighbor counter and group-addressed frame buffer). Set WLAN_STA_PS flag for STA in PS mode to use the unicast frame buffering routines in the tx path. Update num_sta_ps to buffer and release group-addressed frames after DTIM beacons. Announce the awake window duration in beacons if in light or deep sleep mode towards any peer or non-peer. Create a TIM IE similarly to AP mode and add it to mesh beacons. Parse received Awake Window IEs and check TIM IEs for buffered frames. Release frames towards peers in mesh Peer Service Periods. Use the corresponding trigger frames and monitor the MPSP status. Append a QoS Null as trigger frame if neccessary to properly end the MPSP. Currently, in HT channels MPSPs behave imperfectly and show large delay spikes and frame losses.

2013-02-04mac80211: allow transmitting deauth with tainted keyJohannes Berg1-1/+2
When we had a connection for WoWLAN and after resume it needed to be disconnected, the previous commit enabled sending a deauth frame to the AP. This frame would not go through on MFP-enabled networks as the key for it is marked tainted before the frame is transmitted. Allow a tainted key to be used for deauth frames. Worst case, we'll use a wrong key because the PTK was rekeyed while suspended, but more likely the PTK is still fine and the taint flag really only applies to the GTK(s).

2013-02-04cfg80211: fix BSS list hidden SSID lookupJohannes Berg1-27/+53
When trying to find a hidden SSID, the lookup function is done wrong; the code is trying to combine the two lookups into one, and as a consequence doesn't always find the entry at all. To understand this, consider a case where multiple BSS entries with the same channel and BSSID exist but have different SSID length. Then comparing against the probe response SSID length is bound to cause problems since the hidden one might be either zeroed out or zero-length. To fix this we need to do two lookups for the two ways to hide SSIDs. Signed-off-by: Johannes Berg <[email protected]>

2013-02-04mac80211: always allow calling ieee80211_connection_loss()Johannes Berg3-2/+7
