wifi: ath10k: consistently use kstrtoX_from_user() functions

2023-10-02T16:54:51Z

Use 'kstrtoul_from_user()', 'kstrtobool_from_user()' and 'kstrtoint_from_user()' where appropriate and thus avoid some code duplication. Signed-off-by: Dmitry Antipov Acked-by: Jeff Johnson Signed-off-by: Kalle Valo Link: https://lore.kernel.org/r/20230920154018.48314-1-dmantipov@yandex.ru

wifi: ath10k: fix clang-specific fortify warning

2023-09-20T13:39:37Z

When compiling with clang 16.0.6 and CONFIG_FORTIFY_SOURCE=y, I've noticed the following (somewhat confusing due to absence of an actual source code location): In file included from drivers/net/wireless/ath/ath10k/debug.c:8: In file included from ./include/linux/module.h:13: In file included from ./include/linux/stat.h:19: In file included from ./include/linux/time.h:60: In file included from ./include/linux/time32.h:13: In file included from ./include/linux/timex.h:67: In file included from ./arch/x86/include/asm/timex.h:5: In file included from ./arch/x86/include/asm/processor.h:23: In file included from ./arch/x86/include/asm/msr.h:11: In file included from ./arch/x86/include/asm/cpumask.h:5: In file included from ./include/linux/cpumask.h:12: In file included from ./include/linux/bitmap.h:11: In file included from ./include/linux/string.h:254: ./include/linux/fortify-string.h:592:4: warning: call to '__read_overflow2_field' declared with 'warning' attribute: detected read beyond size of field (2nd parameter); maybe use struct_group()? [-Wattribute-warning] __read_overflow2_field(q_size_field, size); The compiler actually complains on 'ath10k_debug_get_et_strings()' where fortification logic inteprets call to 'memcpy()' as an attempt to copy the whole 'ath10k_gstrings_stats' array from it's first member and so issues an overread warning. This warning may be silenced by passing an address of the whole array and not the first member to 'memcpy()'.

wifi: ath10k: Use list_count_nodes()

2023-05-05T13:07:45Z

ath10k_wmi_fw_stats_num_peers() and ath10k_wmi_fw_stats_num_vdevs() really look the same as list_count_nodes(), so use the latter instead of hand writing it. The first ones use list_for_each_entry() and the other list_for_each(), but they both count the number of nodes in the list. Compile tested only.

wifi: Use kstrtobool() instead of strtobool()

2022-11-08T07:39:04Z

strtobool() is the same as kstrtobool(). However, the latter is more used within the kernel. In order to remove strtobool() and slightly simplify kstrtox.h, switch to the other function name. While at it, include the corresponding header file () Signed-off-by: Christophe JAILLET Signed-off-by: Kalle Valo Link: https://lore.kernel.org/r/1ff34549af5ad6f7c80d5b9e11872b5499065fc1.1667336095.git.christophe.jaillet@wanadoo.fr

ath10k: add atomic protection for device recovery

2020-12-12T04:38:12Z

When it has more than one restart_work queued meanwhile, the 2nd restart_work is very easy to break the 1st restart work and lead recovery fail. Add a flag to allow only one restart work running untill device successfully recovered. It already has flag ATH10K_FLAG_CRASH_FLUSH, but it can not use this flag again, because it is clear in ath10k_core_start. The function ieee80211_reconfig(called by ieee80211_restart_work) of mac80211 do many things and drv_start(call to ath10k_core_start) is 1st thing, when drv_start complete, it does not mean restart complete. So it add new flag and clear it in ath10k_reconfig_complete, because it is the last thing called from drv_reconfig_complete of function ieee80211_reconfig, after it, the restart process finished.

ath10k: enable rx duration report default for wmi tlv

2020-04-27T05:01:25Z

When run command "iw dev wlan0 station dump", the rx duration is 0. When firmware indicate WMI_UPDATE_STATS_EVENTID, extended flag of statsis not set by default, so firmware do not report rx duration. one sample: localhost # iw wlan0 station dump Station c4:04:15:5d:97:22 (on wlan0) inactive time: 48 ms rx bytes: 21670 rx packets: 147 tx bytes: 11529 tx packets: 100 tx retries: 88 tx failed: 36 beacon loss: 1 beacon rx: 31 rx drop misc: 47 signal: -72 [-74, -75] dBm signal avg: -71 [-74, -75] dBm beacon signal avg: -71 dBm tx bitrate: 54.0 MBit/s MCS 3 40MHz rx bitrate: 1.0 MBit/s rx duration: 0 us This patch enable firmware's extened flag of stats by setting flag WMI_TLV_STAT_PEER_EXTD of ar->fw_stats_req_mask which is set in ath10k_core_init_firmware_features via WMI_REQUEST_STATS_CMDID. After apply this patch, rx duration show value with the command: Station c4:04:15:5d:97:22 (on wlan0) inactive time: 883 ms rx bytes: 44289 rx packets: 265 tx bytes: 10838 tx packets: 93 tx retries: 899 tx failed: 103 beacon loss: 0 beacon rx: 78 rx drop misc: 46 signal: -71 [-74, -76] dBm signal avg: -70 [-74, -76] dBm beacon signal avg: -70 dBm tx bitrate: 54.0 MBit/s MCS 3 40MHz rx bitrate: 1.0 MBit/s rx duration: 358004 us This patch do not have side effect for all chips, because function ath10k_debug_fw_stats_request is already exported to debugfs "fw_stats" and WMI_REQUEST_STATS_CMDID is safely sent after condition checked by ath10k_peer_stats_enabled in ath10k_sta_statistics.
