2022-08-22ice: xsk: use Rx ring's XDP ring when picking NAPI contextMaciej Fijalkowski
Ice driver allocates per cpu XDP queues so that redirect path can safely use smp_processor_id() as an index to the array. At the same time though, XDP rings are used to pick NAPI context to call napi_schedule() or set NAPIF_STATE_MISSED. When user reduces queue count, say to 8, and num_possible_cpus() of underlying platform is 44, then this means queue vectors with correlated NAPI contexts will carry several XDP queues. This in turn can result in a broken behavior where NAPI context of interest will never be scheduled and AF_XDP socket will not process any traffic. To fix this, let us change the way how XDP rings are assigned to Rx rings and use this information later on when setting ice_tx_ring::xsk_pool pointer. For each Rx ring, grab the associated queue vector and walk through Tx ring's linked list. Once we stumble upon XDP ring in it, assign this ring to ice_rx_ring::xdp_ring. Previous [0] approach of fixing this issue was for txonly scenario because of the described grouping of XDP rings across queue vectors. So, relying on Rx ring meant that NAPI context could be scheduled with a queue vector without XDP ring with associated XSK pool.

2022-08-22ice: xsk: prohibit usage of non-balanced queue idMaciej Fijalkowski
Fix the following scenario: 1. ethtool -L $IFACE rx 8 tx 96 2. xdpsock -q 10 -t -z Above refers to a case where user would like to attach XSK socket in txonly mode at a queue id that does not have a corresponding Rx queue. At this moment ice's XSK logic is tightly bound to act on a "queue pair", e.g. both Tx and Rx queues at a given queue id are disabled/enabled and both of them will get XSK pool assigned, which is broken for the presented queue configuration. This results in the splat included at the bottom, which is basically an OOB access to Rx ring array. To fix this, allow using the ids only in scope of "combined" queues reported by ethtool. However, logic should be rewritten to allow such configurations later on, which would end up as a complete rewrite of the control path, so let us go with this temporary fix.

When the pn532 uart device is detaching, the pn532_uart_remove() is called. But there are no functions in pn532_uart_remove() that could delete the cmd_timeout timer, which will cause use-after-free bugs. The process is shown below: (thread 1) | (thread 2) | pn532_uart_send_frame pn532_uart_remove | mod_timer(&pn532->cmd_timeout,...) ... | (wait a time) kfree(pn532) //FREE | pn532_cmd_timeout | pn532_uart_send_frame | pn532->... //USE This patch adds del_timer_sync() in pn532_uart_remove() in order to prevent the use-after-free bugs. What's more, the pn53x_unregister_nfc() is well synchronized, it sets nfc_dev->shutting_down to true and there are no syscalls could restart the cmd_timeout timer.

2022-08-22mmc: core: Fix inconsistent sd3_bus_mode at UHS-I SD voltage switch failureAdrian Hunter
If re-initialization results is a different signal voltage, because the voltage switch failed previously, but not this time (or vice versa), then sd3_bus_mode will be inconsistent with the card because the SD_SWITCH command is done only upon first initialization. Fix by always reading SD_SWITCH information during re-initialization, which also means it does not need to be re-read later for the 1.8V fixup workaround. Note, brief testing showed SD_SWITCH took about 1.8ms to 2ms which added about 1% to 1.5% to the re-initialization time, so it's not particularly significant.

The devm_add_action_or_reset() does call the release function should adding action fail. The driver inspects the value returned by devm_add_action_or_reset() and manually calls regulator_disable() if adding the action has failed.

2022-08-21i2c: imx: Make sure to unregister adapter on remove()Uwe Kleine-König
If for whatever reasons pm_runtime_resume_and_get() fails and .remove() is exited early, the i2c adapter stays around and the irq still calls its handler, while the driver data and the register mapping go away. So if later the i2c adapter is accessed or the irq triggers this results in havoc accessing freed memory and unmapped registers. So unregister the software resources even if resume failed, and only skip the hardware access in that case.

2022-08-20Revert "zram: remove double compression logic"Jiri Slaby
This reverts commit e7be8d1dd983156b ("zram: remove double compression logic") as it causes zram failures. It does not revert cleanly, PTR_ERR handling was introduced in the meantime. This is handled by appropriate IS_ERR. When under memory pressure, zs_malloc() can fail. Before the above commit, the allocation was retried with direct reclaim enabled (GFP_NOIO). After the commit, it is not -- only __GFP_KSWAPD_RECLAIM is tried. So when the failure occurs under memory pressure, the overlaying filesystem such as ext2 (mounted by ext4 module in this case) can emit failures, making the (file)system unusable: EXT4-fs warning (device zram0): ext4_end_bio:343: I/O error 10 writing to inode 16386 starting block 159744) Buffer I/O error on device zram0, logical block 159744 With direct reclaim, memory is really reclaimed and allocation succeeds, eventually. In the worst case, the oom killer is invoked, which is proper outcome if user sets up zram too large (in comparison to available RAM). This very diff doesn't apply to 5.19 (stable) cleanly (see PTR_ERR note above). Use revert of e7be8d1dd983 directly.

2022-08-19scsi: core: Fix passthrough retry counter handlingMike Christie
Passthrough users will set the scsi_cmnd->allowed value and were expecting up to $allowed retries. The problem is that before: commit 6aded12b10e0 ("scsi: core: Remove struct scsi_request") we used to set the retries on the scsi_request then copy them over to scsi_cmnd->allowed in scsi_setup_scsi_cmnd. With that patch we now set scsi_cmnd->allowed to 0 in scsi_prepare_cmd and overwrite what the passthrough user set. This moves the allowed initialization to after the blk_rq_is_passthrough() check so it's only done for the non-passthrough path where the ULD init_command will normally set an allowed value it prefers.

2022-08-19Revert "net: macsec: update SCI upon MAC address change."Sabrina Dubroca
This reverts commit 6fc498bc82929ee23aa2f35a828c6178dfd3f823. Commit 6fc498bc8292 states: SCI should be updated, because it contains MAC in its first 6 octets. That's not entirely correct. The SCI can be based on the MAC address, but doesn't have to be. We can also use any 64-bit number as the SCI. When the SCI based on the MAC address, it uses a 16-bit "port number" provided by userspace, which commit 6fc498bc8292 overwrites with 1. In addition, changing the SCI after macsec has been setup can just confuse the receiver. If we configure the RXSC on the peer based on the original SCI, we should keep the same SCI on TX. When the macsec device is being managed by a userspace key negotiation daemon such as wpa_supplicant, commit 6fc498bc8292 would also overwrite the SCI defined by userspace.

2022-08-19drm/gem: Fix GEM handle release errorsJeffy Chen
Currently we are assuming a one to one mapping between dmabuf and GEM handle when releasing GEM handles. But that is not always true, since we would create extra handles for the GEM obj in cases like gem_open() and getfb{,2}(). A similar issue was reported at: https://lore.kernel.org/all/20211105083308.392156-1-jay.xu@rock-chips.com/ Another problem is that the imported dmabuf might not always have gem_obj->dma_buf set, which would cause leaks in drm_gem_remove_prime_handles(). Let's fix these for now by using handle to find the exact map to remove.

2022-08-19usb: gadget: f_uac2: fix superspeed transferJing Leng
On page 362 of the USB3.2 specification ( https://usb.org/sites/default/files/usb_32_20210125.zip), The 'SuperSpeed Endpoint Companion Descriptor' shall only be returned by Enhanced SuperSpeed devices that are operating at Gen X speed. Each endpoint described in an interface is followed by a 'SuperSpeed Endpoint Companion Descriptor'. If users use SuperSpeed UDC, host can't recognize the device if endpoint doesn't have 'SuperSpeed Endpoint Companion Descriptor' followed. Currently in the uac2 driver code: 1. ss_epout_desc_comp follows ss_epout_desc; 2. ss_epin_fback_desc_comp follows ss_epin_fback_desc; 3. ss_epin_desc_comp follows ss_epin_desc; 4. Only ss_ep_int_desc endpoint doesn't have 'SuperSpeed Endpoint Companion Descriptor' followed, so we should add it.

2022-08-19Revert "binder_alloc: Add missing mmap_lock calls when using the VMA"Greg Kroah-Hartman
This reverts commit d6f35446d0769a98e9d761593d267cdd24f09ecd. It is coming in through Andrew's tree instead, and for some reason we have different versions. I trust the version from Andrew more as the original offending commit came through his tree.

2022-08-19usb: xhci-mtk: fix bandwidth release issueChunfeng Yun
This happens when @udev->reset_resume is set to true, when usb resume, the flow as below: - hub_resume - usb_disable_interface - usb_disable_endpoint - usb_hcd_disable_endpoint - xhci_endpoint_disable // it set @ep->hcpriv to NULL Then when reset usb device, it will drop allocated endpoints, the flow as below: - usb_reset_and_verify_device - usb_hcd_alloc_bandwidth - xhci_mtk_drop_ep but @ep->hcpriv is already set to NULL, the bandwidth will be not released anymore. Due to the added endponts are stored in hash table, we can drop the check of @ep->hcpriv.
