2024-02-08ASoC: SOF: ipc3-topology: Fix pipeline tear down logicRanjani Sridharan1-14/+41
With the change in the widget free logic to power down the cores only when the scheduler widgets are freed, we need to ensure that the scheduler widget is freed only after all the widgets associated with the scheduler are freed. This is to ensure that the secondary core that the scheduler is scheduled to run on is kept powered on until all widgets that need them are in use. While this works well for dynamic pipelines, in the case of static pipelines the current logic does not take this into account and frees all widgets in the order they occur in the widget_list. So, modify this to ensure that the scheduler widgets are freed only after all other types of widgets in the widget_list are freed.

2024-02-08ASoC: cs35l56: Fix deadlock in ASP1 mixer register initializationRichard Fitzgerald2-82/+73
Rewrite the handling of ASP1 TX mixer mux initialization to prevent a deadlock during component_remove(). The firmware can overwrite the ASP1 TX mixer registers with system-specific settings. This is mainly for hardware that uses the ASP as a chip-to-chip link controlled by the firmware. Because of this the driver cannot know the starting state of the ASP1 mixer muxes until the firmware has been downloaded and rebooted. The original workaround for this was to queue a work function from the dsp_work() job. This work then read the register values (populating the regmap cache the first time around) and then called snd_soc_dapm_mux_update_power(). The problem with this is that it was ultimately triggered by cs35l56_component_probe() queueing dsp_work, which meant that it would be running in parallel with the rest of the ASoC component and card initialization. To prevent accessing DAPM before it was fully initialized the work function took the card mutex. But this would deadlock if cs35l56_component_remove() was called before the work job had completed, because ASoC calls component_remove() with the card mutex held. This new version removes the work function. Instead the regmap cache and DAPM mux widgets are initialized the first time any of the associated ALSA controls is read or written.

2024-02-08wifi: iwlwifi: mvm: fix a crash when we run out of stationsEmmanuel Grumbach2-0/+7
A DoS tool that injects loads of authentication frames made our AP crash. The iwl_mvm_is_dup() function couldn't find the per-queue dup_data which was not allocated. The root cause for that is that we ran out of stations in the firmware and we didn't really add the station to the firmware, yet we didn't return an error to mac80211. Mac80211 was thinking that we have the station and because of that, sta_info::uploaded was set to 1. This allowed ieee80211_find_sta_by_ifaddr() to return a valid station object, but that ieee80211_sta didn't have any iwl_mvm_sta object initialized and that caused the crash mentioned earlier when we got Rx on that station.

2024-02-08wifi: iwlwifi: mvm: use correct address 3 in A-MSDUDaniel Gabay1-10/+59
As described in IEEE sta 802.11-2020, table 9-30 (Address field contents), A-MSDU address 3 should contain the BSSID address. In TX_CMD we copy the MAC header from skb, and skb address 3 holds the destination address, but it may not be identical to the BSSID. Using the wrong destination address appears to work with (most) receivers without MLO, but in MLO some devices are checking for it carefully, perhaps as a consequence of link to MLD address translation. Replace address 3 in the TX_CMD MAC header with the correct address while retaining the skb address 3 unchanged. This ensures that skb address 3 will be utilized later for constructing the A-MSDU subframes. Note that we fill in the MLD address, but the firmware will do the necessary translation to link address after encryption.

2024-02-08netfilter: nft_set_pipapo: store index in scratch mapsFlorian Westphal3-26/+44
Pipapo needs a scratchpad area to keep state during matching. This state can be large and thus cannot reside on stack. Each set preallocates percpu areas for this. On each match stage, one scratchpad half starts with all-zero and the other is inited to all-ones. At the end of each stage, the half that starts with all-ones is always zero. Before next field is tested, pointers to the two halves are swapped, i.e. resmap pointer turns into fill pointer and vice versa. After the last field has been processed, pipapo stashes the index toggle in a percpu variable, with assumption that next packet will start with the all-zero half and sets all bits in the other to 1. This isn't reliable. There can be multiple sets and we can't be sure that the upper and lower half of all set scratch map is always in sync (lookups can be conditional), so one set might have swapped, but other might not have been queried. Thus we need to keep the index per-set-and-cpu, just like the scratchpad. Note that this bug fix is incomplete, there is a related issue. avx2 and normal implementation might use slightly different areas of the map array space due to the avx2 alignment requirements, so m->scratch (generic/fallback implementation) and ->scratch_aligned (avx) may partially overlap. scratch and scratch_aligned are not distinct objects, the latter is just the aligned address of the former. After this change, write to scratch_align->map_index may write to scratch->map, so this issue becomes more prominent, we can set to 1 a bit in the supposedly-all-zero area of scratch->map[]. A followup patch will remove the scratch_aligned and makes generic and avx code use the same (aligned) area. Its done in a separate change to ease review.

2024-02-08s390/qeth: Fix potential loss of L3-IP@ in case of network issuesAlexandra Winter1-3/+6
Symptom: In case of a bad cable connection (e.g. dirty optics) a fast sequence of network DOWN-UP-DOWN-UP could happen. UP triggers recovery of the qeth interface. In case of a second DOWN while recovery is still ongoing, it can happen that the IP@ of a Layer3 qeth interface is lost and will not be recovered by the second UP. Problem: When registration of IP addresses with Layer 3 qeth devices fails, (e.g. because of bad address format) the respective IP address is deleted from its hash-table in the driver. If registration fails because of a ENETDOWN condition, the address should stay in the hashtable, so a subsequent recovery can restore it. 3caa4af834df ("qeth: keep ip-address after LAN_OFFLINE failure") fixes this for registration failures during normal operation, but not during recovery. Solution: Keep L3-IP address in case of ENETDOWN in qeth_l3_recover_ip(). For consistency with qeth_l3_add_ip() we also keep it in case of EADDRINUSE, i.e. for some reason the card already/still has this address registered.

Since commit 48e1b4d369cf ("gpiolib: remove the GPIO device from the list when it's unregistered") we remove the GPIO device entry from the global list (used to order devices by their GPIO ranges) when unregistering the chip, not when releasing the device. It will not happen when the last reference is put anymore. This means, we need to remove it in error path in gpiochip_add_data_with_key() unconditionally, without checking if the device's .release() callback is set.

2024-02-07nilfs2: fix potential bug in end_buffer_async_writeRyusuke Konishi1-3/+5
According to a syzbot report, end_buffer_async_write(), which handles the completion of block device writes, may detect abnormal condition of the buffer async_write flag and cause a BUG_ON failure when using nilfs2. Nilfs2 itself does not use end_buffer_async_write(). But, the async_write flag is now used as a marker by commit 7f42ec394156 ("nilfs2: fix issue with race condition of competition between segments for dirty blocks") as a means of resolving double list insertion of dirty blocks in nilfs_lookup_dirty_data_buffers() and nilfs_lookup_node_buffers() and the resulting crash. This modification is safe as long as it is used for file data and b-tree node blocks where the page caches are independent. However, it was irrelevant and redundant to also introduce async_write for segment summary and super root blocks that share buffers with the backing device. This led to the possibility that the BUG_ON check in end_buffer_async_write would fail as described above, if independent writebacks of the backing device occurred in parallel. The use of async_write for segment summary buffers has already been removed in a previous change. Fix this issue by removing the manipulation of the async_write flag for the remaining super root block buffer.
