2016-05-28wil6210: fix dma mapping error cleanup in __wil_tx_vring_tsoMaya Erez
In case we fail to map one of the TSO SKB fragments, we need to clear all the mapped descriptors, from swhead to swhead+descs_used-1. Change the desc index calculation to i = (swhead + descs_used - 1) % vring->size; to prevent unmpping of (swhead + descs_used) descriptor that wasn't mapped.

2016-05-28wil6210: protect wil_vring_fini_tx in parallel to tx completionsMaya Erez
napi_synchronize is called before releasing the vring, with the assumption that setting txdata->enabled to 0 will prevent handling of this vring in the next scheduled napi. To guarantee this assumption, a memory barrier is added after disabling the txdata. In addition, as the ctx is zeroed in wil_tx_complete after this descriptor is handled (protected by wmb), ctx needs to be checked before releasing this descriptor in wil_vring_free.

2016-05-28wil6210: guarantee safe access to rx descriptors shared memoryMaya Erez
add memory barrier after allocating new rx descriptors, before updating the hwtail. This will guarantee that all writes to descriptors (shared memory) are done before committing them to HW. Signed-off-by: Maya Erez <qca_merez@qca.qualcomm.com> Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>
2016-05-28wil6210: fix race conditions between TX send and completionMaya Erez
There are 2 possible race conditions, both are solved by addition of memory barrier: 1. wil_tx_complete reads the swhead to determine if the vring is empty. In case the swhead was updated before the descriptor update was performed in __wil_tx_vring/__wil_tx_vring_tso, the completion loop will not end and as the DU bit may still be set from a previous run, this skb can be handled as completed before it was sent, which will lead to double free of the same SKB. 2. __wil_tx_vring/__wil_tx_vring_tso calculate the number of available descriptors according to the swtail. In case the swtail is updated before memset of ctx to zero is completed, we can handle this descriptor while later on ctx is zeroed.

2016-05-27remove lots of IS_ERR_VALUE abusesArnd Bergmann
Most users of IS_ERR_VALUE() in the kernel are wrong, as they pass an 'int' into a function that takes an 'unsigned long' argument. This happens to work because the type is sign-extended on 64-bit architectures before it gets converted into an unsigned type. However, anything that passes an 'unsigned short' or 'unsigned int' argument into IS_ERR_VALUE() is guaranteed to be broken, as are 8-bit integers and types that are wider than 'unsigned long'. Andrzej Hajda has already fixed a lot of the worst abusers that were causing actual bugs, but it would be nice to prevent any users that are not passing 'unsigned long' arguments. This patch changes all users of IS_ERR_VALUE() that I could find on 32-bit ARM randconfig builds and x86 allmodconfig. For the moment, this doesn't change the definition of IS_ERR_VALUE() because there are probably still architecture specific users elsewhere. Almost all the warnings I got are for files that are better off using 'if (err)' or 'if (err < 0)'. The only legitimate user I could find that we get a warning for is the (32-bit only) freescale fman driver, so I did not remove the IS_ERR_VALUE() there but changed the type to 'unsigned long'. For 9pfs, I just worked around one user whose calling conventions are so obscure that I did not dare change the behavior. I was using this definition for testing: #define IS_ERR_VALUE(x) ((unsigned long*)NULL == (typeof (x)*)NULL && \ unlikely((unsigned long long)(x) >= (unsigned long long)(typeof(x))-MAX_ERRNO)) which ends up making all 16-bit or wider types work correctly with the most plausible interpretation of what IS_ERR_VALUE() was supposed to return according to its users, but also causes a compile-time warning for any users that do not pass an 'unsigned long' argument. I suggested this approach earlier this year, but back then we ended up deciding to just fix the users that are obviously broken. After the initial warning that caused me to get involved in the discussion (fs/gfs2/dir.c) showed up again in the mainline kernel, Linus asked me to send the whole thing again.

2016-05-27rtlwifi: Fix scheduling while atomic error from commit 49f86ec21c01Larry Finger
Commit 49f86ec21c01 ("rtlwifi: Change long delays to sleeps") was correct for most cases; however, driver rtl8192ce calls the affected routines while in atomic context. The kernel bug output is as follows: BUG: scheduling while atomic: wpa_supplicant/627/0x00000002 [...] [<ffffffff815c2b39>] __schedule+0x899/0xad0 [<ffffffff815c2dac>] schedule+0x3c/0x90 [<ffffffff815c5bb2>] schedule_hrtimeout_range_clock+0xa2/0x120 [<ffffffff810e8b80>] ? hrtimer_init+0x120/0x120 [<ffffffff815c5ba6>] ? schedule_hrtimeout_range_clock+0x96/0x120 [<ffffffff815c5c43>] schedule_hrtimeout_range+0x13/0x20 [<ffffffff815c568f>] usleep_range+0x4f/0x70 [<ffffffffa0667218>] rtl_rfreg_delay+0x38/0x50 [rtlwifi] [<ffffffffa06dd0e7>] rtl92c_phy_config_rf_with_headerfile+0xc7/0xe0 [rtl8192ce] To fix this bug, three of the changes from delay to sleep are reverted. Unfortunately, one of the changes involves a delay of 50 msec. The calling code will be modified so that this long delay can be avoided; however, this change is being pushed now to fix the problem in kernel 4.6.0.

2016-05-24ath10k: reduce warning messages during rx without proper channel contextMohammed Shafi Shajakhan
WARN_ON_ONCE when we receive packets for self peer when mac80211 had not assigned a proper channel context. This scenario happens in QCA4019 when we start the AP via hostapd in background and start it once again in the background without killing the previous instance! This happens intermittently when we start / stop hostapd in a while loop (incase the hostapd is not properly killed). This results in mac80211 chancontext to be unassigned, while the self peer continuous receive packets in target operating channel. This results in lot of call traces in the rx path. Make this as a WARN_ON_ONCE to avoid flooding the console which result in rebooting low memory systems, while still reporting the warning once that we are receiving packets in target operating channel and to indicate that something is happening which is not the expected result.

Store pci chip secific reset funtions in struct ath10k_pci as callbacks during early ath10k_pci_probe() and use the callback to perform chip specific resets. This patch essentially adds two callback in ath10k_pci, one for doing soft reset and the other for hard reset. By using callbacks we can get rid of those hw revision checks in ath10k_pci_safe_chip_reset() and ath10k_pci_chip_reset(). As such this patch does not fix any issue.

2016-05-18iwlwifi: fix mis-merge that breaks the driverLinus Torvalds
My laptop that uses the intel 7680 iwlwifi module would no longer connects to the network. It would fail with a "Microcode SW error detected." and spew out register state over and over again without ever connecting to the network. The cause is mis-merge in commit 909b27f70643, where David seems to have lost some of the changes to iwl_mvm_set_tx_cmd() from commit 5c08b0f5026f ("iwlwifi: mvm: don't override the rate with the AMSDU len"). The reason seems to be a conflict with commit d8fe484470dd ("iwlwifi: mvm: add support for new TX CMD API"), which touched a line adjacent to the changes in 909b27f70643. David missed the fact that "info->driver_data[0]" had become "skb_info->driver_data[0]". Then he removed the skb_info because it was unused. This just re-updates iwl_mvm_set_tx_cmd() with the lost two lines.

rtl_lps_enter does two successive check for cnt_after_linked to make sure some time has elapsed after linked.

2016-05-11rtlwifi: rtl818x: silence uninitialized variable warningDan Carpenter
What about if "rtlphy->pwrgroup_cnt" is 2? In that case we would use an uninitialized "chnlgroup" variable and probably crash. Maybe that can't happen for some reason which is not obvious but in that case this patch is harmless. Setting it to zero seems like a standard default in the surrounding code so it's probably fine here as well.

2016-05-10iwlwifi: pcie: extend device reset delayJohannes Berg
Newer hardware generations will take longer to be accessible again after reset, so we need to wait longer before continuing any flow that did a reset. Rather than make the wait time configurable, simply extend it for all. Since all of these code paths can sleep, use usleep_range() rather than mdelay().

2016-05-10iwlwifi: don't access a nonexistent register upon assertEmmanuel Grumbach
The commit below added code to dump the content of FIFOs that are present only on dual CPU products (8000 and up). This broke 7265D whose firmware does advertise IWL_UCODE_TLV_CAPA_EXTEND_SHARED_MEM_CFG but doesn't have 2 CPUs. The current code does check the length of the FIFO before dumping them (and the nonexistent FIFO has a 0 length), but we still accessed a register to set the FIFO number and that made the DMA unhappy. The impact was a much longer recovery upon firmware assert.
