2023-01-19usb: dwc3: fix extcon dependencyArnd Bergmann
The dwc3 core support now links against the extcon subsystem, so it cannot be built-in when extcon is a loadable module: arm-linux-gnueabi-ld: drivers/usb/dwc3/core.o: in function `dwc3_get_extcon': core.c:(.text+0x572): undefined reference to `extcon_get_edev_by_phandle' arm-linux-gnueabi-ld: core.c:(.text+0x596): undefined reference to `extcon_get_extcon_dev' arm-linux-gnueabi-ld: core.c:(.text+0x5ea): undefined reference to `extcon_find_edev_by_node' There was already a Kconfig dependency in the dual-role support, but this is now needed for the entire dwc3 driver. It is still possible to build dwc3 without extcon, but this prevents it from being set to built-in when extcon is a loadable module.

2023-01-19octeontx2-pf: Fix the use of GFP_KERNEL in atomic context on rtKevin Hao
The commit 4af1b64f80fb ("octeontx2-pf: Fix lmtst ID used in aura free") uses the get/put_cpu() to protect the usage of percpu pointer in ->aura_freeptr() callback, but it also unnecessarily disable the preemption for the blockable memory allocation. The commit 87b93b678e95 ("octeontx2-pf: Avoid use of GFP_KERNEL in atomic context") tried to fix these sleep inside atomic warnings. But it only fix the one for the non-rt kernel. For the rt kernel, we still get the similar warnings like below.

But there are only two ->aura_freeptr() callbacks, otx2_aura_freeptr() and cn10k_aura_freeptr(). There is no usage of perpcu variable in the otx2_aura_freeptr() at all, so the get/put_cpu() seems redundant to it. We can move the get/put_cpu() into the corresponding callback which really has the percpu variable usage and avoid the sprinkling of get/put_cpu() in several places.

2023-01-19tcp: avoid the lookup process failing to get sk in ehash tableJason Xing
While one cpu is working on looking up the right socket from ehash table, another cpu is done deleting the request socket and is about to add (or is adding) the big socket from the table. It means that we could miss both of them, even though it has little chance. Let me draw a call trace map of the server side. CPU 0 CPU 1 ----- ----- tcp_v4_rcv() syn_recv_sock() inet_ehash_insert() -> sk_nulls_del_node_init_rcu(osk) __inet_lookup_established() -> __sk_nulls_add_node_rcu(sk, list) Notice that the CPU 0 is receiving the data after the final ack during 3-way shakehands and CPU 1 is still handling the final ack. Why could this be a real problem? This case is happening only when the final ack and the first data receiving by different CPUs. Then the server receiving data with ACK flag tries to search one proper established socket from ehash table, but apparently it fails as my map shows above. After that, the server fetches a listener socket and then sends a RST because it finds a ACK flag in the skb (data), which obeys RST definition in RFC 793. Besides, Eric pointed out there's one more race condition where it handles tw socket hashdance. Only by adding to the tail of the list before deleting the old one can we avoid the race if the reader has already begun the bucket traversal and it would possibly miss the head. Many thanks to Eric for great help from beginning to end.

2023-01-19nvme-pci: fix timeout request state checkKeith Busch
Polling the completion can progress the request state to IDLE, either inline with the completion, or through softirq. Either way, the state may not be COMPLETED, so don't check for that. We only care if the state isn't IN_FLIGHT. This is fixing an issue where the driver aborts an IO that we just completed. Seeing the "aborting" message instead of "polled" is very misleading as to where the timeout problem resides.

This is a functional revert of c76b8308e4c9 ("nvme-apple: fix controller shutdown in apple_nvme_disable"). The commit broke suspend/resume since apple_nvme_reset_work() tries to disable the controller on resume. This does not work for the apple NVMe controller since register access only works while the co-processor firmware is running. Disabling the NVMe controller in the shutdown path is also required for shutting the co-processor down. The original code was appropriate for this hardware. Add a comment to prevent a similar breaking changes in the future.

2023-01-18Revert "net: team: use IFF_NO_ADDRCONF flag to prevent ipv6 addrconf"Xin Long
This reverts commit 0aa64df30b382fc71d4fb1827d528e0eb3eff854. Currently IFF_NO_ADDRCONF is used to prevent all ipv6 addrconf for the slave ports of team, bonding and failover devices and it means no ipv6 packets can be sent out through these slave ports. However, for team device, "nsna_ping" link_watch requires ipv6 addrconf. Otherwise, the link will be marked failure. This patch removes the IFF_NO_ADDRCONF flag set for team port, and we will fix the original issue in another patch, as Jakub suggested.

Currently, we run into a number of WARN()s when attempting to unload the amdgpu driver (e.g. using "modprobe -r amdgpu"). These all stem from calling drm_encoder_cleanup() too early.

2023-01-18drm/fb-helper: Set framebuffer for vga-switcheroo clientsThomas Zimmermann
Set the framebuffer info for drivers that support VGA switcheroo. Only affects the amdgpu and nouveau drivers, which use VGA switcheroo and generic fbdev emulation. For other drivers, this does nothing. This fixes a potential regression in the console code. Both, amdgpu and nouveau, invoked vga_switcheroo_client_fb_set() from their internal fbdev code. But the call got lost when the drivers switched to the generic emulation. Fixes: 087451f372bf ("drm/amdgpu: use generic fb helpers instead of setting up AMD own's.")

2023-01-18drm/i915: Allow switching away via vga-switcheroo if uninitializedThomas Zimmermann
Always allow switching away via vga-switcheroo if the display is uninitalized. Instead prevent switching to i915 if the device has not been initialized. This issue was introduced by commit 5df7bd130818 ("drm/i915: skip display initialization when there is no display") protected, which protects code paths from being executed on uninitialized devices. In the case of vga-switcheroo, we want to allow a switch away from i915's device. So run vga_switcheroo_process_delayed_switch() and test in the switcheroo callbacks if the i915 device is available.
