2020-05-05net/smc: log important pnetid and state change eventsKarsten Graul8-20/+113
Print to system log when SMC links are available or go down, link group state changes or pnetids are applied to and removed from devices. The log entries are triggered by either user configuration actions or adapter activation/deactivation events and are not expected to happen often. The entries help SMC users to keep track of the SMC link group status and to detect when actions are needed (like to add replacements for failed adapters).

2020-05-05platform/x86: asus-nb-wmi: Do not load on Asus T100TA and T200TAHans de Goede1-0/+24
asus-nb-wmi does not add any extra functionality on these Asus Transformer books. They have detachable keyboards, so the hotkeys are send through a HID device (and handled by the hid-asus driver) and also the rfkill functionality is not used on these devices. Besides not adding any extra functionality, initializing the WMI interface on these devices actually has a negative side-effect. For some reason the \_SB.ATKD.INIT() function which asus_wmi_platform_init() calls drives GPO2 (INT33FC:02) pin 8, which is connected to the front facing webcam LED, high and there is no (WMI or other) interface to drive this low again causing the LED to be permanently on, even during suspend. This commit adds a blacklist of DMI system_ids on which not to load the asus-nb-wmi and adds these Transformer books to this list. This fixes the webcam LED being permanently on under Linux.

2020-05-05ath11k: fix resource unavailability for htt stats after peer stats displaySowmiya Sree Elavalagan1-0/+9
htt stats are not working after htt peer stats display and also after htt peer stats reset. Trying to dump htt stats shows "Resource temporarily unavailable". This is because of "ar->debug.htt_stats.stats_req" member is being consecutively used for all htt stats without being reset during the previous usage. Hence assigning NULL to this member after freeing the allocated memory fixes the issue. console logs below: # echo 9 >/sys/kernel/debug/ath11k/ipq8074/mac1/htt_stats_type # cat /sys/kernel/debug/ath11k/ipq8074/mac1/htt_stats_type 9 # cat /sys/kernel/debug/ath11k/ipq8074/mac1/htt_stats cat: can't open '/sys/kernel/debug/ath11k/ipq8074/mac1/htt_stats' : Resource temporarily unavailable Signed-off-by: Sowmiya Sree Elavalagan <ssreeela@codeaurora.org> Signed-off-by: Kalle Valo <kvalo@codeaurora.org> Link: https://lore.kernel.org/r/1588592755-10427-1-git-send-email-ssreeela@codeaurora.org

2020-05-05ath10k: remove the max_sched_scan_reqs valueWen Gong1-1/+0
The struct cfg80211_wowlan of NET_DETECT WoWLAN feature share the same struct cfg80211_sched_scan_request together with scheduled scan request feature, and max_sched_scan_reqs of wiphy is only used for sched scan, and ath10k does not support scheduled scan request feature, so ath10k does not set flag NL80211_FEATURE_SCHED_SCAN_RANDOM_MAC_ADDR, but ath10k set max_sched_scan_reqs of wiphy to a non zero value 1, then function nl80211_add_commands_unsplit of cfg80211 will set it support command NL80211_CMD_START_SCHED_SCAN because max_sched_scan_reqs is a non zero value, but actually ath10k not support it, then it leads a mismatch result for sched scan of cfg80211, then application shill found the mismatch and stop running case of MAC random address scan and then the case fail. After remove max_sched_scan_reqs value, it keeps match for sched scan and case of MAC random address scan pass. Tested with QCA6174 SDIO with firmware WLAN.RMH.4.4.1-00029.

2020-05-05ath10k: Avoid override CE5 configuration for QCA99X0 chipsetsMaharaja Kennadyrajan4-19/+61
As the exisiting CE configurations are defined in global, there are the chances of QCA99X0 family chipsets CE configurations are getting changed by the ath10k_pci_override_ce_config() function.

Cong Wang says: ==================== net: reduce dynamic lockdep keys syzbot has been complaining about low MAX_LOCKDEP_KEYS for a long time, it is mostly because we register 4 dynamic keys per network device. This patchset reduces the number of dynamic lockdep keys from 4 to 1 per netdev, by reverting to the previous static keys, except for addr_list_lock which still has to be dynamic. The second patch removes a bonding-specific key by the way. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

In function nfp_abm_vnic_set_mac, pointer nsp is allocated by nfp_nsp_open. But when nfp_nsp_has_hwinfo_lookup fail, the pointer is not released, which can lead to a memory leak bug. Fix this issue by adding nfp_nsp_close(nsp) in the error path.

'net-ethernet-ti-k3-introduce-common-platform-time-sync-driver-cpts' Grygorii Strashko says: ==================== net: ethernet: ti: k3: introduce common platform time sync driver - cpts This series introduced support for significantly upgraded TI A65x/J721E Common platform time sync (CPTS) modules which are part of AM65xx Time Synchronization Architecture [1]. The TI A65x/J721E now contain more than one CPTS instance: - MCU CPSW CPTS (IEEE 1588 compliant) - Main NAVSS CPTS (central) - PCIe CPTS(s) (PTM compliant) - J721E: Main CPSW9g CPTS (IEEE 1588 compliant) which can work as separately as interact to each other through Time Sync Router (TSR) and Compare Event Router (CER). In addition there are also ICSS-G IEP blocks which can perform similar timsync functions, but require FW support. More info also available in TRM [2][3]. Not all above modules are available to the Linux by as of now as some of them are reserved for RTOS/FW purposes. The scope of this submission is TI A65x/J721E CPSW CPTS and Main NAVSS CPTS, and TSR was used for testing purposes. +---------------------------+ | MCU CPSW | +-------------------+ +------------------------+ | TS | | Main Navss CPTS | | Time Sync Router (TSR) | | +-------------+ | | | | | | | | | | HW1_TS +<----------+ | | +--------v-----+ +--+--+ | | | | | | CPTS | |Port | | ... | | | X+-->HW1_TS | | | | HW8_TS <------------<---------+ | X|-->HW2_TS | +--^--+ | | | | +--------------->HW3_TS | | | | | | | +--------------->HW4_TS | | | | | | | | | | | | | | | | | | | | | | | | Genf0 +-----------> (A)---------+ +<--------------+Genf0 | | | | | | | | | | | | | | ... | | +-----------> <---------------+Genf1 ESTf+-------+ | | | | | | | | | | | | | | +--------------+ | | Genf8 +---------->+ | | | | | | SYNC0 ...

Main features of the new TI A65x/J721E CPTS modules are: - 64-bit timestamp/counter mode support in ns by using add_val - implemented in HW PPM and nudge adjustment. - control of time sync events via interrupt or polling - selection of multiple external reference clock sources - hardware timestamp of ext. inputs events (HWx_TS_PUSH) - periodic generator function outputs (TS_GENFx) - (CPSW only) Ethernet Enhanced Scheduled Traffic Operations (CPTS_ESTFn), which drives TSN schedule - timestamping of all RX packets bypassing CPTS FIFO Patch 1 - DT bindings Patch 2 - the AM65x/J721E driver Patch 3 - enables packet timestamping support in TI AM65x/J721E MCU CPSW driver.

The CPTS module is used to facilitate host control of time sync operations. Main features of CPTS module are: - selection of multiple external clock sources - control of time sync events via interrupt or polling - 64-bit timestamp mode in ns with HW PPM and nudge adjustment. - hardware timestamp ext. inputs (HWx_TS_PUSH) - timestamp Generator function outputs (TS_GENFx) Depending on integration it enables compliance with the IEEE 1588-2008 standard for a precision clock synchronization protocol, Ethernet Enhanced Scheduled Traffic Operations (CPTS_ESTFn) and PCIe Subsystem Precision Time Measurement (PTM). Introduced driver provides Linux PTP hardware clock for each CPTS device and network packets timestamping where applicable. CPTS PTP hardware clock supports following operations: - Set time - Get time - Shift the clock by a given offset atomically - Adjust clock frequency - Time stamp external events - Periodic output signals Signed-off-by: Grygorii Strashko <grygorii.strashko@ti.com> Signed-off-by: David S.
