[ Upstream commit 476db72e521983ecb847e4013b263072bb1110fc ] Syzkaller reported a warning called "rcu detected stall in dummy_timer". The error seems to be an error in mceusb_dev_recv(). In the case of -EPROTO error, the routine immediately resubmits the URB. Instead it should return without resubmitting URB.

commit fdc881783099c6343921ff017450831c8766d12a upstream. On an Intel NUC6iSYK, no IR is reported after a receive overflow. When a receiver overflow occurs, this condition is only cleared by reading the fifo. Make sure we read anything in the fifo.

2021-07-19media, bpf: Do not copy more entries than user space requestedSean Young1-1/+2
[ Upstream commit 647d446d66e493d23ca1047fa8492b0269674530 ] The syscall bpf(BPF_PROG_QUERY, &attr) should use the prog_cnt field to see how many entries user space provided and return ENOSPC if there are more programs than that. Before this patch, this is not checked and ENOSPC is never returned. Note that one lirc device is limited to 64 bpf programs, and user space I'm aware of -- ir-keytable -- always gives enough space for 64 entries already. However, we should not copy program ids than are requested.

2021-03-17media: rc: compile rc-cec.c into rc-coreHans Verkuil4-18/+18
commit f09f9f93afad770a04b35235a0aa465fcc8d6e3d upstream. The rc-cec keymap is unusual in that it can't be built as a module, instead it is registered directly in rc-main.c if CONFIG_MEDIA_CEC_RC is set. This is because it can be called from drm_dp_cec_set_edid() via cec_register_adapter() in an asynchronous context, and it is not allowed to use request_module() to load rc-cec.ko in that case. Trying to do so results in a 'WARN_ON_ONCE(wait && current_is_async())'. Since this keymap is only used if CONFIG_MEDIA_CEC_RC is set, we just compile this keymap into the rc-core module and never as a separate module.

commit 3f56df4c8ffeb120ed41906d3aae71799b7e726a upstream. If a user holds a button down on a remote, then no ir idle interrupt will be generated until the user releases the button, depending on how quickly the remote repeats. No IR is processed until that point, which means that holding down a button may not do anything. This also resolves an issue on a Cubieboard 1 where the IR receiver is picking up ambient infrared as IR and spews out endless "rc rc0: IR event FIFO is full!" messages unless you choose to live in the dark.

2019-11-29media: mceusb: fix out of bounds read in MCE receiver bufferA Sun1-43/+98
commit e43148645d18efc3072b1ba45afaa3f385299e55 upstream. Fix multiple cases of out of bounds (OOB) read associated with MCE device receive/input data handling. In reference for the OOB cases below, the incoming/read (byte) data format when the MCE device responds to a command is: { cmd_prefix, subcmd, data0, data1, ... } where cmd_prefix are: MCE_CMD_PORT_SYS MCE_CMD_PORT_IR and subcmd examples are: MCE_RSP_GETPORTSTATUS MCE_RSP_EQIRNUMPORTS ... Response size dynamically depends on cmd_prefix and subcmd. So data0, data1, ... may or may not be present on input. Multiple responses may return in a single receiver buffer. The trigger condition for OOB read is typically random or corrupt input data that fills the mceusb receiver buffer. Case 1: mceusb_handle_command() reads data0 (var hi) and data1 (var lo) regardless of whether the response includes such data. If { cmd_prefix, subcmd } is at the end of the receiver buffer, read past end of buffer occurs. This case was reported by KASAN: slab-out-of-bounds Read in mceusb_dev_recv https://syzkaller.appspot.com/bug?extid=c7fdb6cb36e65f2fe8c9 Fix: In mceusb_handle_command(), change variable hi and lo to pointers, and dereference only when required. Case 2: If response with data is truncated at end of buffer after { cmd_prefix, subcmd }, mceusb_handle_command() reads past end of buffer for data0, data1, ... Fix: In mceusb_process_ir_data(), check response size with remaining buffer size before invoking mceusb_handle_command(). + if (i + ir->rem < buf_len) mceusb_handle_command(ir, &ir->buf_in[i - 1]); Case 3: mceusb_handle_command() handles invalid/bad response such as { 0x??, MCE_RSP_GETPORTSTATUS } of length 2 as a response { MCE_CMD_PORT_SYS, MCE_RSP_GETPORTSTATUS, data0, ... } of length 7. Read OOB occurs for non-existent data0, data1, ... Cause is mceusb_handle_command() does not check cmd_prefix value. Fix: mceusb_handle_command() must test both cmd_prefix and subcmd. Case 4: mceusb_process_ir_data() receiver parser state SUBCMD is possible at start (i=0) of receiver buffer resulting in buffer offset=-1 passed to mceusb_dev_printdata(). Bad offset results in OOB read before start of buffer. [1214218.580308] mceusb 1-1.3:1.0: rx data[0]: 00 80 (length=2) [1214218.580323] mceusb 1-1.3:1.0: Unknown command 0x00 0x80 ...

In effect, discard cmd_prefix at end of receiver buffer. In mceusb_dev_printdata(), abort if buffer offset is out of bounds. Case 5: If response with data is truncated at end of buffer after { cmd_prefix, subcmd }, mceusb_dev_printdata() reads past end of buffer for data0, data1, ... while decoding the response to print out. Fix: In mceusb_dev_printdata(), remove unneeded buffer offset adjustments (var start and var skip) associated with MCE gen1 header. Test for truncated MCE cmd response (compare offset+len with buf_len) and skip decoding of incomplete response. Move IR data tracing to execute before the truncation test.

2019-08-21media: mceusb: fix (eliminate) TX IR signal length limitA Sun1-138/+196
Fix and eliminate mceusb's IR length limit for IR signals transmitted to the MCE IR blaster ports. An IR signal TX exceeding 306 pulse/space samples presently causes -EINVAL return error. There's no such limitation nor error with the MCE device hardware. And valid IR signals exist with more than 400 pulse/space for the control of certain appliances (eg Panasonic ACXA75C00600 air conditioner). The scope of this patch is limited to the mceusb driver. There are still IR signal TX length and time constraints that related modules of rc core (eg LIRC) impose, further up the driver stack. Changes for mceusb_tx_ir(): Converts and sends LIRC IR pulse/space sequence to MCE device IR pulse/space format. Break long length LIRC sequence into multiple (unlimited number of) parts for sending to the MCE device. Reduce kernel stack IR buffer size: 128 (was 384) Increase MCE IR data packet size: 31 (was 5) Zero time LIRC pulse/space no longer copied to MCE IR data. Eliminate overwriting the source/input LIRC IR data in txbuf[]. Eliminate -EINVAL return; return number of IR samples sent (>0) or MCE write error code (<0). New mce_write() and mce_write_callback(): Implements synchronous blocking I/O, with timeout, for writing/sending data to the MCE device. An unlimited multipart IR signal sent to the MCE device faster than real time requires flow control absent with the original mce_request_packet() and mce_async_callback() asynchronous I/O implementation. Also absent is TX error feedback. mce_write() combines and replaces mce_request_packet() and mce_async_callback() with conversion to synchronous I/O. mce_write() returns bytes sent (>0) or MCE device write error (<0). Debug hex dump TX data before processing. Rename mce_async_out() -> mce_command_out(): The original name is misleading with underlying synchronous I/O implementation. Function renamed to mce_command_out(). Changes in mceusb_handle_command(): Add support for MCE device error case MCE_RSP_TX_TIMEOUT "IR TX timeout (TX buffer underrun)" Changes in mceusb_dev_printdata(): Changes support test and debug of multipart TX IR. Add buffer boundary information (offset and buffer size) to TX hex dump. Correct TX trace bug "Raw IR data, 0 pulse/space samples" Add trace for MCE_RSP_TX_TIMEOUT "IR TX timeout (TX buffer underrun)" Other changes: The driver's write to USB device architecture change (async to sync I/O) is significant so we bump DRIVER_VERSION to "1.95" (from "1.94").

2019-07-22media: mceusb: USB reset device following USB clear halt errorA Sun1-12/+55
This patch schedules a USB reset device call following a USB clear halt error. The issues solved, and patch implementation, are similar to those found in drivers/hid/usbhid/hid-core.c. As seen on very rare occasions approximately one time per month (mceusb device 2304:0225 in this sample) Jul 27 2018 15:09:39 [59388.696941] mceusb 1-1.1.2:1.0: Error: urb status = -32 (RX HALT) [59388.698838] mceusb 1-1.1.2:1.0: rx clear halt error -32 the device can get into RX or TX HALT state where usb_clear_halt() also fails and also returns -EPIPE (HALT/STALL). After which, all further mceusb device control and data I/O always fail with HALT/STALL. Subsequently, the entire mceusb device no longer functions. Cause and problem replication conditions remain unknown. Further troubleshooting reveals usb_reset_device() restores mceusb device operation. Patch test 1: Hot unplugging the mceusb device triggers USB RX HALT and USB clear halt errors. A mceusb_dev_disconnect() call follows unplug. This patch's reset device call invokes an extra mceusb_dev_probe() mceusb_dev_disconnect() cycle, before the mceusb driver detaches. The additional probe/disconnect verifies the patch's device reset code executed. But note this patch is for USB clear halt error cases not caused by unplugging the mceusb device. Patch test 2: Simulate a RX HALT and a clear halt error with instrumented code in the driver.

The result matches what is expected when the device gets into a real rx clear halt error case by itself. This is the same sequence of messages when manually invoking the ./usbreset command line utility with an unpatched mceusb driver.

RC_PROTO_BIT_ALL includes protocols like unknown and other that do not have IR decoders by definition. If these protocols are set in the allowed_protocols, they will show in the protocols sysfs file but cannot be enabled.
