commit bd05a5bd upstream. We don't really need clear the skb's status area nor store the dev_cmd into it until we really commit to the frame by handing it to the transport - defer those operations until just before we do that. This doesn't entirely fix the bug with frames not getting sent out after having been deferred due to DQA, because it doesn't restore the info->driver_data[0] place that was already set to zero (or another value) by the A-MSDU logic.

commit ba1c7e45 upstream. The mwifiex_dbg() log handler utilizes the struct device in adapter->dev. Without it, it decides not to print anything. As of commit 2e02b581 ("mwifiex: Allow mwifiex early access to device structure"), we started assigning that pointer only after we finished mwifiex_register() -- this effectively neuters any mwifiex_dbg() logging done before this point. Let's move the device assignment into mwifiex_register(). Fixes: 2e02b581 ("mwifiex: Allow mwifiex early access to device structure") Cc: Rajat Jain <rajatja@google.com> Signed-off-by:

commit 2447e2ca upstream. If we don't have an out-of-band wakeup IRQ configured through DT (as most platforms don't), then we fall out of this function with 'irq_wakeup == 0'. Other code (e.g., mwifiex_disable_wake() and mwifiex_enable_wake()) treats 'irq_wakeup >= 0' as a valid IRQ, and so we end up calling {enable,disable}_irq() on IRQ 0. That seems bad, so let's not do that. Same problem as fixed in this patch: https://patchwork.kernel.org/patch/9531693/ [PATCH v2 2/3] btmrvl: set irq_bt to -1 when failed to parse it with the difference that: (a) this one is actually a regression and (b) this affects both device tree and non-device-tree systems While fixing the regression, also drop the verbosity on the parse failure, so we don't see this when a DT node is present but doesn't have an interrupt property (this is perfectly legal): [ 21.999000] mwifiex_pcie 0000:01:00.0: fail to parse irq_wakeup from device tree Fixes: 853402a0 ("mwifiex: Enable WoWLAN for both sdio and pcie") Signed-off-by:

commit a5b60de6 upstream. This patch fixes the issue specific to AP. AP is started with WEP security and external station is connected to it. Data path works in this case. Now if AP is restarted with WPA/WPA2 security, station is able to connect but ping fails. Driver skips the deletion of WEP keys if interface type is AP. Removing that redundant check resolves the issue. Fixes: e57f1734 ("mwifiex: add key material v2 support") Signed-off-by:

commit 5f0a221f upstream. We already ensure 64 bytes alignment and add padding if required during skb_aggr allocation. Alignment and padding in mwifiex_11n_form_amsdu_txpd() is redundant.

commit 6183468a upstream. Similar to commit fcd2042e ("mwifiex: printk() overflow with 32-byte SSIDs"), we failed to account for the existence of 32-char SSIDs in our debugfs code. Unlike in that case though, we zeroed out the containing struct first, and I'm pretty sure we're guaranteed to have some padding after the 'ssid.ssid' and 'ssid.ssid_len' fields (the struct is 33 bytes long). So, this is the difference between: # cat /sys/kernel/debug/mwifiex/mlan0/info ... essid="0123456789abcdef0123456789abcdef " ... and the correct output: # cat /sys/kernel/debug/mwifiex/mlan0/info ... essid="0123456789abcdef0123456789abcdef" ...

commit ec663d96 upstream. Commit cab15ce6 ("arm64: Introduce execute-only page access permissions") allowed a valid user PTE to have the PTE_USER bit clear. As a consequence, the pte_valid_not_user() macro in set_pte() was replaced with pte_valid_global() under the assumption that only user pages have the nG bit set. EFI mappings, however, also have the nG bit set and set_pte() wrongly ignores issuing the DSB+ISB. This patch reinstates the pte_valid_not_user() macro and adds the PTE_UXN bit check since all kernel mappings have this bit set. For clarity, pte_exec() is renamed to pte_user_exec() as it only checks for the absence of PTE_UXN. Consequently, the user executable check in set_pte_at() drops the pte_ng() test since pte_user_exec() is sufficient.

commit 68abfb80 upstream. Caching the fault register after a single I2C read may not keep an accurate value. Fix by doing two reads in irq_handle_thread() and using the cached value elsewhere. If a safety timer fault later clears itself, we apparently don't get an interrupt (INT), however other interrupts would refresh the register cache. From the data sheet: "When a fault occurs, the charger device sends out INT and keeps the fault state in REG09 until the host reads the fault register. Before the host reads REG09 and all the faults are cleared, the charger device would not send any INT upon new faults. In order to read the current fault status, the host has to read REG09 two times consecutively. The 1st reads fault register status from the last read [1] and the 2nd reads the current fault register status." [1] presumably a typo; should be "last fault" Fixes: d7bf353f ("bq24190_charger: Add support for TI BQ24190 Battery Charger") Signed-off-by:

commit bdd9968d upstream. val might become 7 in which case stime[7] (array of length 7) would be accessed during the scnprintf call later and that will cause issues. Obviously, string concatenation is not intended here so just a comma needs to be added to fix the issue. Fixes: 98a27664 ("power_supply: Add new lp8788 charger driver") Signed-off-by:
