2022-02-21ath11k: Replace zero-length arrays with flexible-array membersGustavo A. R. Silva5-11/+11
There is a regular need in the kernel to provide a way to declare having a dynamically sized set of trailing elements in a structure. Kernel code should always use “flexible array members”[1] for these cases. The older style of one-element or zero-length arrays should no longer be used[2].

2022-02-21ath9k: use hw_random API instead of directly dumping into random.cJason A. Donenfeld2-42/+33
Hardware random number generators are supposed to use the hw_random framework. This commit turns ath9k's kthread-based design into a proper hw_random driver.

2022-02-14ath11k: fix destination monitor ring out of syncKarthikeyan Kathirvel2-6/+39
More than 20000 PPDU id jumping causing status ring and destination ring processing not sync. The status ring is processed and the destination ring is not processed. Since destination is not reaped for so long, backpressure occurs at the destination ring. To address this issue update the PPDU id with the latest PPDU, this will allow the destination ring to be reaped and will prevent the rings from getting out of sync.

2022-02-14ath11k: fix radar detection in 160 MhzVenkateswara Naralasetty1-12/+13
Radar detection fails in the secondary 80 MHz when the the AP's primary 80 MHz is in non-DFS region in 160 MHz. This is due to WMI channel flag WMI_CHAN_INFO_DFS_FREQ2 is not set properly in case of the primary 80 MHz is in non-DFS region. HALPHY detects the radar pulses in the secondary 80 MHz only when WMI_CHAN_INFO_DFS_FREQ2 is set. Fix this issue by setting WMI channel flag WMI_CHAN_INFO_DFS_FREQ2 based on the radar_enabled flag from the channel context.

Add debugfs interface "fw_dbglog_config" to configure firmware log level. Configuration is done via WMI command WMI_DBGLOG_CFG_CMDID. Command to configure, echo "<dbglog_param> <values>" > /sys/kernel/debug/ath11k/<hw>/macX/fw_dbglog_config where dbglog_param can be, 1) WMI_DEBUG_LOG_PARAM_LOG_LEVEL - configure log level for a given module here, <values> = <0xaaaa00bb>, 'aaaa' - module id and 'bb' - loglevel 2) WMI_DEBUG_LOG_PARAM_VDEV_ENABLE - enable debug log for a given vdev here, <values> = vdev_id 3) WMI_DEBUG_LOG_PARAM_VDEV_DISABLE - disable debug log for a given vdev except ERROR logs here, <values> = vdev_id 4) WMI_DEBUG_LOG_PARAM_VDEV_ENABLE_BITMAP - set vdev enable bitmap here, <values> = vdev_enable_bitmap 5) WMI_DEBUG_LOG_PARAM_MOD_ENABLE_BITMAP - set a given log level to all the modules specified in the module bitmap. Command to configure for this log param, $ echo "5 <values> <module_id_index> <is_end>" > /sys/kernel/debug/ath11k/<hw>/macX/fw_dbglog_config here, <values> = <0xaaaaaaaa000000bb>, 'aaaaaaaa' - module bitmap and 'bb' - loglevel <module_id_index> = index of module bitmap. Max module id is 512. So, module_id_index is 0-15. <is_end> = to indicate if more configuration to follow. 6) WMI_DEBUG_LOG_PARAM_WOW_MOD_ENABLE_BITMAP - Wow mode specific logging enable. Command to configure for this log param, $ echo "6 <values> <module_id_index> <is_end>" > /sys/kernel/debug/ath11k/<hw>/macX/fw_dbglog_config here, <values> = <0xaaaaaaaa000000bb>, 'aaaaaaaa' - module bitmap and 'bb' - loglevel <module_id_index> = index of module bitmap.

Currently tx_params is being re-assigned with a new value and the previous setting IEEE80211_HT_MCS_TX_RX_DIFF is being overwritten. The assignment operator is incorrect, the original intent was to bit-wise or the value in. Fix this by replacing the = operator with |= instead.

2022-01-31ath11k: mhi: use mhi_sync_power_up()Kalle Valo1-1/+1
If amss.bin was missing ath11k would crash during 'rmmod ath11k_pci'. The reason for that was that we were using mhi_async_power_up() which does not check any errors. But mhi_sync_power_up() on the other hand does check for errors so let's use that to fix the crash. I was not able to find a reason why an async version was used. ath11k_mhi_start() (which enables state ATH11K_MHI_POWER_ON) is called from ath11k_hif_power_up(), which can sleep. So sync version should be safe to use here.

2022-01-28ath11k: avoid firmware crash when reg set for QCA6390/WCN6855Wen Gong3-8/+24
For the NL80211_REGDOM_SET_BY_USER hint from cfg80211, it set the new alpha2 code to ath11k, then ath11k send WMI_SET_INIT_COUNTRY_CMDID to firmware for all chips currently. When test with WCN6855/QCA6390 chips, this WMI CMD leads firmware crash. For AP based chips(ipq8074/qcn9074), WMI_SET_INIT_COUNTRY_CMDID is used to send to firmware, for STATION based chips(WCN6855/QCA6390), it need to use another WMI CMD WMI_SET_CURRENT_COUNTRY_CMDID. Add flag current_cc_support in hardware parameters, it is used to distinguish AP/STA platform. After that, the firmware will work normal and the regulatory feature works well for QCA6390/WCN6855.

Syzbot reported 2 KMSAN bugs in ath9k. All of them are caused by missing field initialization. In htc_connect_service() svc_meta_len and pad are not initialized. Based on code it looks like in current skb there is no service data, so simply initialize svc_meta_len to 0. htc_issue_send() does not initialize htc_frame_hdr::control array. Based on firmware code, it will initialize it by itself, so simply zero whole array to make KMSAN happy Fail logs: BUG: KMSAN: kernel-usb-infoleak in usb_submit_urb+0x6c1/0x2aa0 drivers/usb/core/urb.c:430 usb_submit_urb+0x6c1/0x2aa0 drivers/usb/core/urb.c:430 hif_usb_send_regout drivers/net/wireless/ath/ath9k/hif_usb.c:127 [inline] hif_usb_send+0x5f0/0x16f0 drivers/net/wireless/ath/ath9k/hif_usb.c:479 htc_issue_send drivers/net/wireless/ath/ath9k/htc_hst.c:34 [inline] htc_connect_service+0x143e/0x1960 drivers/net/wireless/ath/ath9k/htc_hst.c:275 ...

Pavel Begunkov says: ==================== udp/ipv6 optimisations Shed some weight from udp/ipv6. Zerocopy benchmarks over dummy showed ~5% tx/s improvement, should be similar for small payload non-zc cases. The performance comes from killing 4 atomics and a couple of big struct memcpy/memset. 1/10 removes a pair of atomics on dst refcounting for cork->skb setup, 9/10 saves another pair on cork init. 5/10 and 8/10 kill extra 88B memset and memcpy respectively. ==================== Link: https://lore.kernel.org/r/cover.1643243772.git.asml.silence@gmail.com Signed-off-by: Jakub Kicinski <kuba@kernel.org>

2022-01-28ipv6: optimise dst refcounting on cork initPavel Begunkov2-5/+11
udpv6_sendmsg() doesn't need dst after calling ip6_make_skb(), so instead of taking an additional reference inside ip6_setup_cork() and releasing the initial one afterwards, we can hand over a reference into ip6_make_skb() saving two atomics. The only other user of ip6_setup_cork() is ip6_append_data() and it requires an extra dst_hold().

udpv6_sendmsg() first initialises an on-stack 88B struct flowi6 and then copies it into cork, which is expensive. Avoid the copy in corkless case by initialising on-stack cork->fl directly.

Another preparation patch. inet_cork_full already contains a field for iflow, so we can avoid passing a separate struct iflow6 into __ip6_append_data() and ip6_make_skb(), and use the flow stored in inet_cork_full.

2022-01-28mlxsw: spectrum_acl: Allocate default actions for internal TCAM regionsIdo Schimmel2-1/+13
In Spectrum-2 and later ASICs, each TCAM region has a default action that is executed in case a packet did not match any rule in the region. The location of the action in the database (KVDL) is computed by adding the region's index to a base value. Some TCAM regions are not exposed to the host and used internally by the device. Allocate KVDL entries for the default actions of these regions to avoid the host from overwriting them. With mlxsw, lookups in the internal regions are not currently performed, but it is a good practice not to overwrite their default actions.

2022-01-28mlxsw: spectrum: Guard against invalid local portsAmit Cohen4-7/+10
When processing events generated by the device's firmware, the driver protects itself from events reported for non-existent local ports, but not for the CPU port (local port 0), which exists, but does not have all the fields as any local port. This can result in a NULL pointer dereference when trying access 'struct mlxsw_sp_port' fields which are not initialized for CPU port. Commit 63b08b1f6834 ("mlxsw: spectrum: Protect driver from buggy firmware") already handled such issue by bailing early when processing a PUDE event reported for the CPU port. Generalize the approach by moving the check to a common function and making use of it in all relevant places.

However, multi table actions (e.g. CT) instantiate multiple attr instances. This is a refactoring series in a preparation to support multiple attribute instances per flow.
