This code is really spurious. It always returns an ERR_PTR, even when err is known to be 0 and calls put_device() after a successful device_register() call. It is likely that the return statement in the normal path is missing. Add 'return rdev;' to fix it.

2022-04-21memory: renesas-rpc-if: Fix HF/OSPI data transfer in Manual ModeGeert Uytterhoeven1-14/+46
HyperFlash devices fail to probe: rpc-if-hyperflash rpc-if-hyperflash: probing of hyperbus device failed In HyperFlash or Octal-SPI Flash mode, the Transfer Data Enable bits (SPIDE) in the Manual Mode Enable Setting Register (SMENR) are derived from half of the transfer size, cfr. the rpcif_bits_set() helper function. However, rpcif_reg_{read,write}() does not take the bus size into account, and does not double all Manual Mode Data Register access sizes when communicating with a HyperFlash or Octal-SPI Flash device. Fix this, and avoid the back-and-forth conversion between transfer size and Transfer Data Enable bits, by explicitly storing the transfer size in struct rpcif, and using that value to determine access size in rpcif_reg_{read,write}(). Enforce that the "high" Manual Mode Read/Write Data Registers (SM[RW]DR1) are only used for 8-byte data accesses. While at it, forbid writing to the Manual Mode Read Data Registers, as they are read-only.

2022-04-12bus: ti-sysc: Make omap3 gpt12 quirk handling SoC specificTony Lindgren1-1/+15
On beagleboard revisions A to B4 we need to use gpt12 as the system timer. However, the quirk handling added for gpt12 caused a regression for system suspend for am335x as the PM coprocessor needs the timers idled for suspend. Let's make the gpt12 quirk specific to omap34xx, other SoCs don't need it. Beagleboard revisions C and later no longer need to use the gpt12 related quirk. Then at some point, if we decide to drop support for the old beagleboard revisions A to B4, we can also drop the gpt12 related quirks completely.

2022-04-04firmware: arm_scmi: Remove clear channel call on the TX channelCristian Marussi1-1/+2
On SCMI transports whose channels are based on a shared resource the TX channel area has to be acquired by the agent before placing the desired command into the channel and it will be then relinquished by the platform once the related reply has been made available into the channel. On an RX channel the logic is reversed with the platform acquiring the channel area and the agent reliquishing it once done by calling the scmi_clear_channel() helper. As a consequence, even in case of error, the agent must never try to clear a TX channel from its side: restrict the existing clear channel call on the the reply path only to delayed responses since they are indeed coming from the RX channel.

2022-04-01dm: fix bio polling to handle possibile BLK_STS_AGAINMing Lei1-7/+13
Expanded testing of DM's bio polling support (using more fio threads to dm-linear ontop of null_blk) exposed the possibility for polled bios to hang (repeatedly polling in io_uring) when null_blk responds with BLK_STS_AGAIN (due to lack of resources): 1) io_complete_rw_iopoll() is called from blkdev_bio_end_io_async() to notify kiocb is done, that is the completion interface between block layer and io_uring 2) io_complete_rw_iopoll() is called from io_do_iopoll() 3) dm returns BLK_STS_AGAIN for one bio (on behalf of underlying driver), then io_complete_rw_iopoll is called, but io_do_iopoll() doesn't handle -EAGAIN at all (due to logic in io_rw_should_reissue) 4) reason for dm's BLK_STS_AGAIN is underlying null_blk driver ran out of requests (easier to reproduce by setting low hw_queue_depth). 5) dm should handle BLK_STS_AGAIN for POLLED underlying IO, and may retry in dm layer. This fix adds REQ_POLLED specific BLK_STS_AGAIN handling to dm_io_complete() that clears REQ_POLLED and requeues the bio to DM using queue_io().

2022-03-31Revert "Input: clear BTN_RIGHT/MIDDLE on buttonpads"José Expósito1-6/+0
This reverts commit 37ef4c19b4c659926ce65a7ac709ceaefb211c40. The touchpad present in the Dell Precision 7550 and 7750 laptops reports a HID_DG_BUTTONTYPE of type MT_BUTTONTYPE_CLICKPAD. However, the device is not a clickpad, it is a touchpad with physical buttons. In order to fix this issue, a quirk for the device was introduced in libinput [1] [2] to disable the INPUT_PROP_BUTTONPAD property: [Precision 7x50 Touchpad] MatchBus=i2c MatchUdevType=touchpad MatchDMIModalias=dmi:*svnDellInc.:pnPrecision7?50* AttrInputPropDisable=INPUT_PROP_BUTTONPAD However, because of the change introduced in 37ef4c19b4 ("Input: clear BTN_RIGHT/MIDDLE on buttonpads") the BTN_RIGHT key bit is not mapped anymore breaking the device right click button and making impossible to workaround it in user space. In order to avoid breakage on other present or future devices, revert the patch causing the issue.

2022-03-31platform/chrome: cros_ec_debugfs: detach log reader wq from devmTzung-Bi Shih1-6/+6
Debugfs console_log uses devm memory (e.g. debug_info in cros_ec_console_log_poll()). However, lifecycles of device and debugfs are independent. An use-after-free issue is observed if userland program operates the debugfs after the memory has been freed. The call trace: do_raw_spin_lock _raw_spin_lock_irqsave remove_wait_queue ep_unregister_pollwait ep_remove do_epoll_ctl A Python example to reproduce the issue: ... import select ... p = select.epoll() ... f = open('/sys/kernel/debug/cros_scp/console_log') ... p.register(f, select.POLLIN) ... p.poll(1) [(4, 1)] # 4=fd, 1=select.POLLIN [ shutdown cros_scp at the point ] ... p.poll(1) [(4, 16)] # 4=fd, 16=select.POLLHUP ... p.unregister(f) An use-after-free issue raises here. It called epoll_ctl with EPOLL_CTL_DEL which in turn to use the workqueue in the devm (i.e. log_wq). Detaches log reader's workqueue from devm to make sure it is persistent even if the device has been removed.

2022-03-31drbd: remove check of list iterator against head past the loop bodyJakob Koschel1-15/+27
When list_for_each_entry() completes the iteration over the whole list without breaking the loop, the iterator value will be a bogus pointer computed based on the head element. While it is safe to use the pointer to determine if it was computed based on the head element, either with list_entry_is_head() or &pos->member == head, using the iterator variable after the loop should be avoided. In preparation to limit the scope of a list iterator to the list traversal loop, use a dedicated pointer to point to the found element [1].

Since that variable should not be used past the loop iteration, a separate variable is used to 'remember the current location within the loop'.

2022-03-31random: mix build-time latent entropy into pool at initJason A. Donenfeld1-0/+5
Prior, the "input_pool_data" array needed no real initialization, and so it was easy to mark it with __latent_entropy to populate it during compile-time. In switching to using a hash function, this required us to specifically initialize it to some specific state, which means we dropped the __latent_entropy attribute. An unfortunate side effect was this meant the pool was no longer seeded using compile-time random data. In order to bring this back, we declare an array in rand_initialize() with __latent_entropy and call mix_pool_bytes() on that at init, which accomplishes the same thing as before. We make this __initconst, so that it doesn't take up space at runtime after init.
