2023-06-14wifi: iwlwifi: pcie: clear FW debug memory on initJohannes Berg
When we restart the firmware, we shouldn't keep old debug data around. Since the "allocate" function might not reallocate the memory block (it's only freed when we unbind from the device), clear the memory to have a clean slate for debug data.

2023-06-14wifi: iwlwifi: dbg-tlv: fix DRAM data initJohannes Berg
Given the existing code in iwl_dbg_tlv_update_drams(), the following can happen and cause firmware asserts, and even the device to become unusable: * We set the magic so the firmware will use the data; * we try to fill multiple allocation IDs, with at least one successful, but - crucially - one failing and thus not touching the data; * we don't clear the data since there was one success. This doesn't seem like much of a problem just yet, however, what happens now is that the allocation ID(s) that failed are not initialized. There are two additional things to know: * we never free these allocations across FW restart or interface down/up etc., in fact we never free them until the driver is unbound from the device (e.g. unloaded) * the firmware uses the DRAM info structure for real debug data when it has used it completely Given that, and the fact that we never initialize the data on restart, we can be unlucky and end up with an allocation that looks for the most part valid (valid ID, valid number of buffers, etc.) but has bad sizes - causing the firmware to throw an assert we can never recover from. Fixing the code to have the entire buffers cleared (which we should do so old debug data isn't sticking around) is a bit more complex, so as a first step make the actual code that fills the information more robust by clearing the structure first, and filling the magic values only if it actually succeeded for one, rather than doing it the other way around.

2023-06-14wifi: iwlwifi: mvm: put only a single IGTK into FWJohannes Berg
The firmware only supports a single IGTK, and due to some changes it really doesn't like to have multiple programmed in later versions. Since only newer firmware cannot remove a key that isn't present any more, adjust only the MLD API code to keep track of the previous IGTK and remove it when a new one is added.

2023-06-13wifi: ath9k: Fix possible stall on ath9k_txq_list_has_key()Remi Pommarel
On EDMA capable hardware, ath9k_txq_list_has_key() can enter infinite loop if it is called while all txq_fifos have packets that use different key that the one we are looking for. Fix it by exiting the loop if all txq_fifos have been checked already. Because this loop is called under spin_lock_bh() (see ath_txq_lock) it causes the following rcu stall: rcu: INFO: rcu_sched self-detected stall on CPU ath10k_pci 0000:01:00.0: failed to read temperature -11 rcu: 1-....: (5254 ticks this GP) idle=189/1/0x4000000000000002 softirq=8442983/8442984 fqs=2579 (t=5257 jiffies g=17983297 q=334) Task dump for CPU 1: task:hostapd state:R running task stack: 0 pid: 297 ppid: 289 flags:0x0000000a Call trace: dump_backtrace+0x0/0x170 show_stack+0x1c/0x24 sched_show_task+0x140/0x170 dump_cpu_task+0x48/0x54 rcu_dump_cpu_stacks+0xf0/0x134 rcu_sched_clock_irq+0x8d8/0x9fc update_process_times+0xa0/0xec tick_sched_timer+0x5c/0xd0 __hrtimer_run_queues+0x154/0x320 hrtimer_interrupt+0x120/0x2f0 arch_timer_handler_virt+0x38/0x44 handle_percpu_devid_irq+0x9c/0x1e0 handle_domain_irq+0x64/0x90 gic_handle_irq+0x78/0xb0 call_on_irq_stack+0x28/0x38 do_interrupt_handler+0x54/0x5c el1_interrupt+0x2c/0x4c el1h_64_irq_handler+0x14/0x1c el1h_64_irq+0x74/0x78 ath9k_txq_has_key+0x1bc/0x250 [ath9k] ath9k_set_key+0x1cc/0x3dc [ath9k] drv_set_key+0x78/0x170 ieee80211_key_replace+0x564/0x6cc ieee80211_key_link+0x174/0x220 ieee80211_add_key+0x11c/0x300 nl80211_new_key+0x12c/0x330 genl_family_rcv_msg_doit+0xbc/0x11c genl_rcv_msg+0xd8/0x1c4 netlink_rcv_skb+0x40/0x100 genl_rcv+0x3c/0x50 netlink_unicast+0x1ec/0x2c0 netlink_sendmsg+0x198/0x3c0 ____sys_sendmsg+0x210/0x250 ___sys_sendmsg+0x78/0xc4 __sys_sendmsg+0x4c/0x90 __arm64_sys_sendmsg+0x28/0x30 invoke_syscall.constprop.0+0x60/0x100 do_el0_svc+0x48/0xd0 el0_svc+0x14/0x50 el0t_64_sync_handler+0xa8/0xb0 el0t_64_sync+0x158/0x15c This rcu stall is hard to reproduce as is, but changing ATH_TXFIFO_DEPTH from 8 to 2 makes it reasonably easy to reproduce.

2023-06-13octeontx2-af: Set XOFF on other child transmit schedulers during SMQ flushNaveen Mamindlapalli
When multiple transmit scheduler queues feed a TL1 transmit link, the SMQ flush initiated on a low priority queue might get stuck when a high priority queue fully subscribes the transmit link. This inturn effects interface teardown. To avoid this, temporarily XOFF all TL1's other immediate child transmit scheduler queues and also clear any rate limit configuration on all the scheduler queues in SMQ(flush) hierarchy.
