2022-11-15net: dsa: don't leak tagger-owned storage on switch driver unbindVladimir Oltean
In the initial commit dc452a471dba ("net: dsa: introduce tagger-owned storage for private and shared data"), we had a call to tag_ops->disconnect(dst) issued from dsa_tree_free(), which is called at tree teardown time. There were problems with connecting to a switch tree as a whole, so this got reworked to connecting to individual switches within the tree. In this process, tag_ops->disconnect(ds) was made to be called only from switch.c (cross-chip notifiers emitted as a result of dynamic tag proto changes), but the normal driver teardown code path wasn't replaced with anything. Solve this problem by adding a function that does the opposite of dsa_switch_setup_tag_protocol(), which is called from the equivalent spot in dsa_switch_teardown(). The positioning here also ensures that we won't have any use-after-free in tagging protocol (*rcv) ops, since the teardown sequence is as follows: dsa_tree_teardown -> dsa_tree_teardown_master -> dsa_master_teardown -> unsets master->dsa_ptr, making no further packets match the ETH_P_XDSA packet type handler -> dsa_tree_teardown_ports -> dsa_port_teardown -> dsa_slave_destroy -> unregisters DSA net devices, there is even a synchronize_net() in unregister_netdevice_many() -> dsa_tree_teardown_switches -> dsa_switch_teardown -> dsa_switch_teardown_tag_protocol -> finally frees the tagger-owned storage Fixes: 7f2973149c22 ("net: dsa: make tagging protocols connect to individual switches from a tree") Signed-off-by: Vladimir Oltean <vladimir.oltean@nxp.com> Reviewed-by: Saeed Mahameed <saeed@kernel.org> Reviewed-by: Florian Fainelli <f.fainelli@gmail.com> Link: https://lore.kernel.org/r/20221114143551.1906361-1-vladimir.oltean@nxp.com Signed-off-by: Jakub Kicinski <kuba@kernel.org>

2022-11-15drm/display: Don't assume dual mode adaptors support i2c sub-addressingSimon Rettberg
Current dual mode adaptor ("DP++") detection code assumes that all adaptors support i2c sub-addressing for read operations from the DP-HDMI adaptor ID buffer. It has been observed that multiple adaptors do not in fact support this, and always return data starting at register 0. On affected adaptors, the code fails to read the proper registers that would identify the device as a type 2 adaptor, and handles those as type 1, limiting the TMDS clock to 165MHz, even if the according register would announce a higher TMDS clock. Fix this by always reading the ID buffer starting from offset 0, and discarding any bytes before the actual offset of interest. We tried finding authoritative documentation on whether or not this is allowed behaviour, but since all the official VESA docs are paywalled, the best we could come up with was the spec sheet for Texas Instruments' SNx5DP149 chip family.[1] It explicitly mentions that sub-addressing is supported for register writes, but *not* for reads (See NOTE in section 8.5.3). Unless TI openly decided to violate the VESA spec, one could take that as a hint that sub-addressing is in fact not mandated by VESA. The other two adaptors affected used the PS8409(A) and the LT8611, according to the data returned from their ID buffers.

2022-11-15netfs: Fix missing xas_retry() calls in xarray iterationDavid Howells
netfslib has a number of places in which it performs iteration of an xarray whilst being under the RCU read lock. It *should* call xas_retry() as the first thing inside of the loop and do "continue" if it returns true in case the xarray walker passed out a special value indicating that the walk needs to be redone from the root[*]. Fix this by adding the missing retry checks. [*] I wonder if this should be done inside xas_find(), xas_next_node() and suchlike, but I'm told that's not an simple change to effect.

2022-11-15platform/surface: aggregator_registry: Add support for Surface Pro 9Maximilian Luz
Add device nodes to enable support for battery and charger status, the ACPI platform profile, as well as internal and type-cover HID devices (including sensors, touchpad, keyboard, and other miscellaneous devices) on the Surface Pro 9. This does not include support for a tablet-mode switch yet, as that is now handled via the POS subsystem (unlike the Surface Pro 8, where it is handled via the KIP subsystem) and therefore needs further changes. While we're at it, also add the missing comment for the Surface Pro 8.

2022-11-15platform/surface: aggregator: Do not check for repeated unsequenced packetsMaximilian Luz
Currently, we check any received packet whether we have already seen it previously, regardless of the packet type (sequenced / unsequenced). We do this by checking the sequence number. This assumes that sequence numbers are valid for both sequenced and unsequenced packets. However, this assumption appears to be incorrect. On some devices, the sequence number field of unsequenced packets (in particular HID input events on the Surface Pro 9) is always zero. As a result, the current retransmission check kicks in and discards all but the first unsequenced packet, breaking (among other things) keyboard and touchpad input. Note that we have, so far, only seen packets being retransmitted in sequenced communication. In particular, this happens when there is an ACK timeout, causing the EC (or us) to re-send the packet waiting for an ACK. Arguably, retransmission / duplication of unsequenced packets should not be an issue as there is no logical condition (such as an ACK timeout) to determine when a packet should be sent again. Therefore, remove the retransmission check for unsequenced packets entirely to resolve the issue.

2022-11-15platform/x86/intel: pmc: Don't unconditionally attach Intel PMC when virtualizedRoger Pau Monné
The current logic in the Intel PMC driver will forcefully attach it when detecting any CPU on the intel_pmc_core_platform_ids array, even if the matching ACPI device is not present. There's no checking in pmc_core_probe() to assert that the PMC device is present, and hence on virtualized environments the PMC device probes successfully, even if the underlying registers are not present. Before commit 21ae43570940 ("platform/x86: intel_pmc_core: Substitute PCI with CPUID enumeration") the driver would check for the presence of a specific PCI device, and that prevented the driver from attaching when running virtualized. Fix by only forcefully attaching the PMC device when not running virtualized. Note that virtualized platforms can still get the device to load if the appropriate ACPI device is present on the tables provided to the VM. Make an exception for the Xen initial domain, which does have full hardware access, and hence can attach to the PMC if present.

2022-11-15MAINTAINERS: add entries for misc. RISC-V SoC drivers and devicetreesConor Dooley
Following some discussion both on & off list, I have volunteered to take over maintaining the miscellaneous RISC-V devicetrees & soc drivers from Palmer to ease his load. So far only SiFive and Microchip have stuff in drivers/soc. For the former, a SiFive entry exists with a dead GitHub repo - so remove that to avoid confusion since the patches for drivers/soc & devicetrees will be routed via my tree & other drivers go through their subsystem trees. The Microchip directory only contains a RISC-V driver for now, but is likely to contain drivers for other archs in the future. To that end, change the PolarFire SoC entry to specifically mention the RISC-V driver & the new directory level entry does not mention an architecture.

2022-11-15bridge: switchdev: Fix memory leaks when changing VLAN protocolIdo Schimmel
The bridge driver can offload VLANs to the underlying hardware either via switchdev or the 8021q driver. When the former is used, the VLAN is marked in the bridge driver with the 'BR_VLFLAG_ADDED_BY_SWITCHDEV' private flag. To avoid the memory leaks mentioned in the cited commit, the bridge driver will try to delete a VLAN via the 8021q driver if the VLAN is not marked with the previously mentioned flag. When the VLAN protocol of the bridge changes, switchdev drivers are notified via the 'SWITCHDEV_ATTR_ID_BRIDGE_VLAN_PROTOCOL' attribute, but the 8021q driver is also called to add the existing VLANs with the new protocol and delete them with the old protocol. In case the VLANs were offloaded via switchdev, the above behavior is both redundant and buggy. Redundant because the VLANs are already programmed in hardware and drivers that support VLAN protocol change (currently only mlx5) change the protocol upon the switchdev attribute notification. Buggy because the 8021q driver is called despite these VLANs being marked with 'BR_VLFLAG_ADDED_BY_SWITCHDEV'. This leads to memory leaks [1] when the VLANs are deleted. Fix by not calling the 8021q driver for VLANs that were already programmed via switchdev.
