| | * | | ath: regd: add extra US coutry codesOever Gonzalez2019-02-072-0/+4

Without this patch, all devices whose manufacturer programmed any of these code in their EEPROM will not work. The values for CTRY_UNITED_STATES2 and CTRY_UNITED_STATES3 were taken from a post by Sven Eckelmann <sven.eckelmann@openmesh.com>: <http://lists.infradead.org/pipermail/ath10k/2017-August/010014.html> Signed-off-by: Oever Gonzalez <notengobattery@gmail.com> Signed-off-by: Christian Lamparter <chunkeey@gmail.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>

| | * | | ath10k: fix hw-restart crash inject mode for WCN3990Rakesh Pillai2019-02-071-1/+10

In order to restart WCN3990 firmware, the driver needs to send qmi_wlan_disable message followed by the qmi_wlan_enable message to the WCN3990 firmware. Currently the qmi_wlan_disable message is not sent to the WCN3990 firmware when hw-restart crash is injected, which causes the firmware to crash when the driver sends qmi_wlan_enable message during ath10k_restart. Send qmi_wlan_disable to the WCN3990 firmware when the hw-restart crash is injected via debugfs.

| | * | | ath9k: eeprom: Use scnprintf instead of snprintfKees Cook2019-02-041-6/+6

There are generally two cases where using snprintf causes problems. 1) Uses of size += snprintf(buf, SIZE - size, fmt, ...) In this case, if snprintf would have written more characters than what the buffer size (SIZE) is, then size will end up larger than SIZE. In later uses of snprintf, SIZE - size will result in a negative number, leading to problems. Note that size might already be too large by using size = snprintf before the code reaches a case of size += snprintf. 2) If size is ultimately used as a length parameter for a copy back to user space, then it will potentially allow for a buffer overflow and information disclosure when size is greater than SIZE. When the size is used to index the buffer directly, we can have memory corruption. This also means when size = snprintf... is used, it may also cause problems since size may become large. Copying to userspace is mitigated by the HARDENED_USERCOPY kernel configuration. The solution to these issues is to use scnprintf which returns the number of characters actually written to the buffer, so the size variable will never exceed SIZE.

The 36th bit is used to control the smmu/iommu translation and the 37th bit is used by the internal bus masters to access the wifi subsystem internal SRAM. With the DMA mask set to 37i-bit, the host driver can get 37-bit dma address, which leads to incorrect address access in the target. Hence the host driver can used addresses upto 35-bit for WCN3990. Fix the dma mask for wcn3990 to 35-bit, instead of 37-bit.

In case the driver reaches the maximum amount of blocks allowed, it allocates the buffer and only then checks if it reached the maximum amount of blocks and return without freeing the buffer, causing a memory leak. Solve this by moving the check of the amount of buffers being used before the allocation. In case there was an assert, the apply points are being reused, causing that for each assert, the driver allocates a new redundant buffer. Solve this by adding a new is_alloc field to indicate if the driver already allocated memory for the requested buffer. Also, split iwl_fw_dbg_buffer_allocation function into iwl_fw_dbg_buffer_allocation and iwl_fw_dbg_buffer_apply to increase the clearity of the flow.

When we implemented that, we forgot to remove the key when we remove a station leading to a situation where a station that connects and disconnects a lot of times exhausts the key database inside the firmware. A fix was made for that, but we always removed the same key: mvmvif->ap_wep_key which means that we removed the same key entry in the firmware. This can make sense since in WEP, the key is the same for all the stations, but the internal implementation of iwl_mvm_set_sta_key and iwl_mvm_remove_sta_key assumes that each station uses a different key in the firmware's key database. So now we got to the situation where we have a single ieee80211_key_conf instance that means, a single ieee80211_key_conf.hw_key_idx index for several stations and hence for several keys. ieee80211_key_conf.hw_key_idx is set to 0 when the first station associates, and then it is overwritten to 1 when the second station associates which is a buggy of course. This led to the following message upon the removal of the second station: iwlwifi 0000:00:03.0: offset 1 not used in fw key table. WARNING: CPU: 2 PID: 27883 at net/mac80211/sta_info.c:1122 __sta_info_destroy_part2+0x16b/0x180 [mac80211] RIP: 0010:__sta_info_destroy_part2+0x16b/0x180 [mac80211] Call Trace: __sta_info_destroy+0x2a/0x40 [mac80211] sta_info_destroy_addr_bss+0x38/0x60 [mac80211] ieee80211_del_station+0x1d/0x30 [mac80211] nl80211_del_station+0xe0/0x1f0 [cfg80211] Fix this by copying the ieee80211_key_conf structure for each and every station. This is the easiest way to properly remove the keys with the right index. Another solution would have been to allow several stations to use the same key offset in the firmware. That would require to change the way we track keys in iwlmvm and not really worth it. Also, maintain correctly fw_key_table when we add a key for the multicast station. Remove the key when we remove the multicast station.
