2015-07-31rtlwifi: Fix NULL dereference when PCI driver used as an APLuis Felipe Dominguez Vega1-2/+5
In commit 33511b157bbcebaef853cc1811992b664a2e5862 ("rtlwifi: add support to send beacon frame"), the mechanism for sending beacons was established. That patch works correctly for rtl8192cu, but there is a possibility of getting the following warnings in the PCI drivers: WARNING: CPU: 1 PID: 2439 at net/mac80211/driver-ops.h:12 ieee80211_bss_info_change_notify+0x179/0x1d0 [mac80211]() wlp5s0: Failed check-sdata-in-driver check, flags: 0x0 The warning is followed by a NULL pointer dereference as follows: BUG: unable to handle kernel NULL pointer dereference at 0000000000000006 IP: [<ffffffffc073998e>] rtl_get_tcb_desc+0x5e/0x760 [rtlwifi] This problem was reported at http://thread.gmane.org/gmane.linux.kernel.wireless.general/138645, but no solution was found at that time. The problem was also reported at https://bugzilla.kernel.org/show_bug.cgi?id=9744 and this solution was developed and tested there. The USB driver works with a NULL final argument in the adapter_tx() callback; however, the PCI drivers need a struct rtl_tcb_desc in that position.

2015-07-31rsi: Fix failure to load firmware after memory leak fix and fix the leakMike Looijmans2-1/+11
Fixes commit eae79b4f3e82 ("rsi: fix memory leak in rsi_load_ta_instructions()") which stopped the driver from functioning. Firmware data has been allocated using vmalloc(), resulting in memory that cannot be used for DMA. Hence the firmware was first copied to a buffer allocated with kmalloc() in the original code. This patch reverts the commit and only calls "kfree()" to release the buffer after sending the data. This fixes the memory leak without breaking the driver. Add a comment to the kmemdup() calls to explain why this is done, and abort if memory allocation fails. Tested on a Topic Miami-Florida board which contains the rsi SDIO chip. Also added the same kfree() call to the USB glue driver. This was not tested on actual hardware though, as I only have the SDIO version.

2015-07-30iwlwifi: pcie: fix stuck queue detection for sleeping clientsEmmanuel Grumbach1-2/+13
The stuck queue detection mechanism allows to detect queues that are stuck. For sleeping clients, a queue may rightfully be stuck: if a poor client implementation stays asleep for more than 10s, then we don't want to trigger recovery flows because of that client. In order to cope with this, I added a mechanism that monitors the state of the client: when a client goes to sleep, the timer of his queues is frozen. When he wakes up, the timer is reset to the right value so that if a client was awake for more than 10s and the queues are stuck, only then, the recovery flow will kick in. This is valid only on non-shared queues: A-MPDU queues. There was a bug in case we Tx to a sleeping client that has an empty A-MPDU queue: the timer was armed to now + 10s. This is bad, but pretty harmless. The problem is that when the client wakes up, the timer is modified to be now + remainder. But remainder is 0 since the queue was empty when that client went to sleep... Fix this by checking the state of the client before playing with the timer when we add a packet to an empty queue.

2015-07-28iwlwifi: mvm: Fix regular scan priorityAvraham Stern1-1/+1
The code checks the total number of iterations to differentiate between regular scan and scheduled scan. However, regular scan has a total of one iteration, not zero. As a result, regular scan will have lower priority than it should have, and in case scheduled scan is already running when regular scan is requested, regular scan will be delayed until scheduled scan is aborted. Fix that by checking for total iterations number of one as an identifier for regular scan.

2015-07-28iwlwifi: pcie: fix prepare card flowEmmanuel Grumbach1-3/+19
When the card is not owned by the PCIe bus, we need to acquire ownership first. This flow is implemented in iwl_pcie_prepare_card_hw. Because of a hardware bug, we need to disable link power management before we can request ownership otherwise the other user of the device won't get notified that we are requesting the device which will prevent us from acquire ownership. Same holds for the down flow where we need to make sure that any other potential user is notified that the driver is going down.

The time event is initialized relatively late in interface (mvmvif) initialization, so it's possible to fail before that happens. As a consequence, the driver will crash if it ever tries to delete this time event in case initialization was unsuccessful. Avoid this by using the time event's vif pointer to indicate validity. The vif pointer is != NULL whenever the id is != TE_MAX, except for this special error case where the vif pointer will have the correct property (as the whole memory is cleared on allocation) whereas the id is 0, causing a crash in trying to delete the time event from the list.

2015-06-26iwlwifi: mvm: fix antenna selection when BT is activeEmmanuel Grumbach1-1/+1
When BT is active, we want to avoid the shared antenna for management frame to make sure we don't disturb BT. There was a bug in that code because it chose the antenna BIT(ANT_A) where ANT_A is already a bitmap (0x1). This means that the antenna chosen in the end was ANT_B. While this is not optimal on devices with 2 antennas (it'd disturb BT), it is critical on single antenna devices like 3160 which couldn't connect at all when BT was active.

2015-06-23module: add per-module param_lockDan Streetman1-3/+3
Add a "param_lock" mutex to each module, and update params.c to use the correct built-in or module mutex while locking kernel params. Remove the kparam_block_sysfs_r/w() macros, replace them with direct calls to kernel_param_[un]lock(module). The kernel param code currently uses a single mutex to protect modification of any and all kernel params. While this generally works, there is one specific problem with it; a module callback function cannot safely load another module, i.e. with request_module() or even with indirect calls such as crypto_has_alg(). If the module to be loaded has any of its params configured (e.g. with a /etc/modprobe.d/* config file), then the attempt will result in a deadlock between the first module param callback waiting for modprobe, and modprobe trying to lock the single kernel param mutex to set the new module's param. This fixes that by using per-module mutexes, so that each individual module is protected against concurrent changes in its own kernel params, but is not blocked by changes to other module params. All built-in modules continue to use the built-in mutex, since they will always be loaded at runtime and references (e.g. request_module(), crypto_has_alg()) to them will never cause load-time param changing. This also simplifies the interface used by modules to block sysfs access to their params; while there are currently functions to block and unblock sysfs param access which are split up by read and write and expect a single kernel param to be passed, their actual operation is identical and applies to all params, not just the one passed to them; they simply lock and unlock the global param mutex. They are replaced with direct calls to kernel_param_[un]lock(THIS_MODULE), which locks THIS_MODULE's param_lock, or if the module is built-in, it locks the built-in mutex.
