2022-10-11drm/i915/display: consider DG2_RC_CCS_CC when migrating buffersMatthew Auld
For these types of display buffers, we need to able to CPU access some part of the backing memory in prepare_plane_clear_colors(). As a result we need to ensure we always place in the mappable part of lmem, which becomes necessary on small-bar systems. v2(Nirmoy & Ville): - Add some commentary for why we need to CPU access the buffer. - Split out the other changes, so we just consider the display change here. v3: - Handle this in the dpt path. v4(Ville): - Drop the intel_fb_rc_ccs_cc_plane() sanity check in pin_and_fence_fb_obj(), since we can also trigger this on DG1 it seems.

Commit 39a2bd34c933 ("drm/i915: Use the vma resource as argument for gtt binding / unbinding") introduced a regression that due to the vma resource tracking of the binding state, dpt ptes were not correctly repopulated.

2022-10-11wifi: ath11k: mac: fix reading 16 bytes from a region of size 0 warningKalle Valo
Linaro reported stringop-overread warnings in ath11k (this is one of many): drivers/net/wireless/ath/ath11k/mac.c:2238:29: error: 'ath11k_peer_assoc_h_he_limit' reading 16 bytes from a region of size 0 [-Werror=stringop-overread] My further investigation showed that these warnings happen on GCC 11.3 but not with GCC 12.2, and with only the kernel config Linaro provided: https://builds.tuxbuild.com/2F4W7nZHNx3T88RB0gaCZ9hBX6c/config I saw the same warnings both with arm64 and x86_64 builds and KASAN seems to be the reason triggering these warnings with GCC 11. Nobody else has reported this so this seems to be quite rare corner case. I don't know what specific commit started emitting this warning so I can't provide a Fixes tag. The function hasn't been touched for a year. I decided to workaround this by converting the pointer to a new array in stack, and then copying the data to the new array. It's only 16 bytes anyway and this is executed during association, so not in a hotpath.

Checking the relevant rxd bits for the checksum information only indicates if the checksum verification was performed by the hardware and doesn't show actual checksum errors. Checksum errors are indicated in the info field of the DMA descriptor. Fix packets erroneously marked as CHECKSUM_UNNECESSARY by checking the extra bits as well. Those bits are only passed to the driver for MMIO devices at the moment, so limit checksum offload to those.

2022-10-11wifi: mt76: fix receiving LLC packets on mt7615/mt7915Felix Fietkau
When 802.3 decap offload is enabled, the hardware indicates header translation failure, whenever either the LLC-SNAP header was not found, or a VLAN header with an unregcognized tag is present. In that case, the hardware inserts a 2-byte length fields after the MAC addresses. For VLAN packets, this tag needs to be removed. However, for 802.3 LLC packets, the length bytes should be preserved, since there is no separate ethertype field in the data. This fixes an issue where the length field was omitted for LLC frames, causing them to be malformed after hardware decap.

2022-10-11ALSA: oss: Fix potential deadlock at unregistrationTakashi Iwai
We took sound_oss_mutex around the calls of unregister_sound_special() at unregistering OSS devices. This may, however, lead to a deadlock, because we manage the card release via the card's device object, and the release may happen at unregister_sound_special() call -- which will take sound_oss_mutex again in turn. Although the deadlock might be fixed by relaxing the rawmidi mutex in the previous commit, it's safer to move unregister_sound_special() calls themselves out of the sound_oss_mutex, too. The call is race-safe as the function has a spinlock protection by itself.

The register_mutex taken around the dev_unregister callback call in snd_rawmidi_free() may potentially lead to a mutex deadlock, when OSS emulation and a hot unplug are involved. Since the mutex doesn't protect the actual race (as the registration itself is already protected by another means), let's drop it.

2022-10-11can: kvaser_usb_leaf: Fix TX queue out of sync after restartAnssi Hannula
The TX queue seems to be implicitly flushed by the hardware during bus-off or bus-off recovery, but the driver does not reset the TX bookkeeping. Despite not resetting TX bookkeeping the driver still re-enables TX queue unconditionally, leading to "cannot find free context" / NETDEV_TX_BUSY errors if the TX queue was full at bus-off time. Fix that by resetting TX bookkeeping on CAN restart. Tested with 0bfd:0124 Kvaser Mini PCI Express 2xHS FW 4.18.778.

2022-10-11can: kvaser_usb: Fix use of uninitialized completionAnssi Hannula
flush_comp is initialized when CMD_FLUSH_QUEUE is sent to the device and completed when the device sends CMD_FLUSH_QUEUE_RESP. This causes completion of uninitialized completion if the device sends CMD_FLUSH_QUEUE_RESP before CMD_FLUSH_QUEUE is ever sent (e.g. as a response to a flush by a previously bound driver, or a misbehaving device). Fix that by initializing flush_comp in kvaser_usb_init_one() like the other completions. This issue is only triggerable after RX URBs have been set up, i.e. the interface has been opened at least once.

2022-10-11can: kvaser_usb_leaf: Fix overread with an invalid commandAnssi Hannula
For command events read from the device, kvaser_usb_leaf_read_bulk_callback() verifies that cmd->len does not exceed the size of the received data, but the actual kvaser_cmd handlers will happily read any kvaser_cmd fields without checking for cmd->len. This can cause an overread if the last cmd in the buffer is shorter than expected for the command type (with cmd->len showing the actual short size). Maximum overread seems to be 22 bytes (CMD_LEAF_LOG_MESSAGE), some of which are delivered to userspace as-is. Fix that by verifying the length of command before handling it. This issue can only occur after RX URBs have been set up, i.e. the interface has been opened at least once.

2022-10-10clk: Update req_rate on __clk_recalc_rates()Maxime Ripard
Commit cb1b1dd96241 ("clk: Set req_rate on reparenting") introduced a new function, clk_core_update_orphan_child_rates(), that updates the req_rate field on reparenting. It turns out that that function will interfere with the clock notifying done by __clk_recalc_rates(). This ends up reporting the new rate in both the old_rate and new_rate fields of struct clk_notifier_data. Since clk_core_update_orphan_child_rates() is basically __clk_recalc_rates() without the notifiers, and with the req_rate field update, we can drop clk_core_update_orphan_child_rates() entirely, and make __clk_recalc_rates() update req_rate. However, __clk_recalc_rates() is being called in several code paths: when retrieving a rate (most likely through clk_get_rate()), when changing parents (through clk_set_rate() or clk_hw_reparent()), or when updating the orphan status (through clk_core_reparent_orphans_nolock(), called at registration). Updating req_rate on reparenting or initialisation makes sense, but we shouldn't do it on clk_get_rate(). Thus an extra flag has been added to update or not req_rate depending on the context.
