2024-02-27wifi: brcmfmac: fweh: Fix boot crash on Raspberry Pi 4Gustavo A. R. Silva
Fix boot crash on Raspberry Pi by moving the update to `event->datalen` before data is copied into flexible-array member `data` via `memcpy()`. Flexible-array member `data` was annotated with `__counted_by(datalen)` in commit 62d19b358088 ("wifi: brcmfmac: fweh: Add __counted_by for struct brcmf_fweh_queue_item and use struct_size()"). The intention of this is to gain visibility into the size of `data` at run-time through its _counter_ (in this case `datalen`), and with this have its accesses bounds-checked at run-time via CONFIG_FORTIFY_SOURCE and CONFIG_UBSAN_BOUNDS. To effectively accomplish the above, we shall update the counter (`datalen`), before the first access to the flexible array (`data`), which was also done in the mentioned commit. However, commit edec42821911 ("wifi: brcmfmac: allow per-vendor event handling") inadvertently caused a buffer overflow, detected by FORTIFY_SOURCE. It moved the `event->datalen = datalen;` update to after the first `data` access, at which point `event->datalen` was not yet updated from zero (after calling `kzalloc()`), leading to the overflow issue. This fix repositions the `event->datalen = datalen;` update before accessing `data`, restoring the intended buffer overflow protection. :) Fixes: edec42821911 ("wifi: brcmfmac: allow per-vendor event handling") Reported-by: Nathan Chancellor <nathan@kernel.org> Closes: https://gist.github.com/nathanchance/e22f681f3bfc467f15cdf6605021aaa6 Tested-by: Nathan Chancellor <nathan@kernel.org> Signed-off-by: Gustavo A.

2024-02-23wifi: ath11k: thermal: don't try to register multiple timesKalle Valo
Every time the firmware boots we call ath11k_core_qmi_firmware_ready() which ends up calling ath11k_thermal_register(). So we try to register thermal devices multiple times. And when we power off the firmware during suspend/hibernation (implemented in the next patch) we get a warning in resume: hwmon hwmon4: PM: parent phy0 should not be sleeping Workaround this similarly like ath11k_mac_register() does by testing ATH11K_FLAG_REGISTERED.

2024-02-23wifi: ath11k: do not dump SRNG statistics during resumeBaochen Qiang
Both the firmware reset feature and the power management suspend/resume feature share common power-down and power-up functionality. One aspect of the power-up functionality is the handling of the ATH11K_QMI_EVENT_FW_INIT_DONE event. When this event is received, a call is made to ath11k_hal_dump_srng_stats(), with the purpose to collect information that may be useful in debugging the cause of a firmware reset. Unfortunately, since this functionality is shared between both the firmware reset path and the power management resume path, the kernel log is flooded with messages during resume. Since these messages are not useful during resume, and in fact can be confusing and can increase the time it takes to resume, update the logic to only call ath11k_hal_dump_srng_stats() during firmware reset.

2024-02-22bonding: rate-limit bonding driver inspect messagesPraveen Kumar Kannoju
Through the routine bond_mii_monitor(), bonding driver inspects and commits the slave state changes. During the times when slave state change and failure in aqcuiring rtnl lock happen at the same time, the routine bond_mii_monitor() reschedules itself to come around after 1 msec to commit the new state. During this, it executes the routine bond_miimon_inspect() to re-inspect the state chane and prints the corresponding slave state on to the console. Hence we do see a message at every 1 msec till the rtnl lock is acquired and state chage is committed. This patch doesn't change how bond functions. It only simply limits this kind of log flood.

2024-02-22bnxt_en: Provision for an additional VNIC for ntuple filtersPavan Chebbi
On newer chips that support the ring table index method for ntuple filters, the current scheme of using the same VNIC for both RSS and ntuple filters will not work in all cases. An ntuple filter can only be directed to a destination ring if that destination ring is also in the RSS indirection table. To support ntuple filters with any arbitratry RSS indirection table that may only include a subset of the rings, we need to use a separate VNIC for ntuple filters. This patch provisions the additional VNIC. The next patch will allocate additional VNIC from firmware and set it up.

2024-02-22wifi: mt76: mt7921: fix suspend issue on MediaTek COB platformMichael Lo
MediaTek's controller driver on COB platform (e.g. MT8188) is capable of controlling power supplies and reset pin of a component (e.g. a WIFI chip) in power-on and power-off process. Due to this optional feature, mt76 need to inform controller that mt76 need to keep power during suspend. Otherwise WIFI will be powered off when system enters suspend process. The "wakeup-source" property was used for the device that need this to go into suspend mode so that mt76 suspend handler doesn't fail and the system is able to enter into a suspend state. An example: wifi: mt7921@0 { wifi0{ reg = <0x0000 0 0 0 0>; wakeup-source; }; }; Signed-off-by: Michael Lo <michael.lo@mediatek.com> Signed-off-by: Ming Yen Hsieh <MingYen.Hsieh@mediatek.com> Signed-off-by: Felix Fietkau <nbd@nbd.name>
2024-02-22wifi: mt76: mt7921: fix a potential association failure upon resumingLeon Yen
In multi-channel scenarios, the granted channel must be aborted before suspending. Otherwise, the firmware will be put into a wrong state, resulting in an association failure after resuming. With this patch, the granted channel will be aborted before suspending if necessary.
