2022-07-29tty: the rest, stop using tty_schedule_flip()Jiri Slaby
commit b68b914494df4f79b4e9b58953110574af1cb7a2 upstream. Since commit a9c3f68f3cd8d (tty: Fix low_latency BUG) in 2014, tty_flip_buffer_push() is only a wrapper to tty_schedule_flip(). We are going to remove the latter (as it is used less), so call the former in the rest of the users.

2022-07-29pinctrl: ralink: Check for null return of devm_kcallocWilliam Dean
[ Upstream commit c3b821e8e406d5650e587b7ac624ac24e9b780a8 ] Because of the possible failure of the allocation, data->domains might be NULL pointer and will cause the dereference of the NULL pointer later. Therefore, it might be better to check it and directly return -ENOMEM without releasing data manually if fails, because the comment of the devm_kmalloc() says "Memory allocated with this function is automatically freed on driver detach.".

commit 242439f7e279d86b3f73b5de724bc67b2f8aeb07 upstream. The expression for setting the size of the allocated bulk TX buffer (`devpriv->usb_tx_buf`) is calling `usb_endpoint_maxp(devpriv->ep_rx)`, which is using the wrong endpoint (should be `devpriv->ep_tx`). Fix it.

[ Upstream commit 6256e18686158fa49e019297f990f1c1817aabf1 ] Fix LED and pinctrl definitions on the GB-PC1 devicetree. Refer to the schematics of the device for more information. LED fixes: - Change GPIO6 LED label from system to power as GPIO6 is connected to PLED. - Add default-on default-trigger to power LED. - Change GPIO8 LED label from status to system as GPIO8 is connected to SYS_LED. - Add disk-activity default-trigger to system LED. - Switch to the color:function naming scheme. - Remove lan1 and lan2 LEDs as they don't exist. Pinctrl fixes: - Claim state_default node under pinctrl node. - Change pinctrl0 node name to state-default. - Change gpio node name to gpio-pinmux to respect Documentation/devicetree/bindings/pinctrl/ralink,rt2880-pinmux.yaml. - Sort pin groups alphabetically. Misc fixes: - Fix formatting. - Use the status value "okay". - Define hexadecimal addresses in lower case. - Make hexadecimal addresses for memory easier to read.

[ Upstream commit 2e81948177d769106754085c3e03534e6cc1f623 ] As the possible alloc failure of devm_kcalloc(), it could return null pointer. Therefore, 'strings' should be checked and return NULL if alloc fails to prevent the dereference of the NULL pointer. Also, the caller should also deal with the return value of the gb_generate_enum_strings() and return -ENOMEM if returns NULL. Moreover, because the memory allocated with devm_kzalloc() will be freed automatically when the last reference to the device is dropped, the 'gbe' in gbaudio_tplg_create_enum_kctl() and gbaudio_tplg_create_enum_ctl() do not need to free manually. But the 'control' in gbaudio_tplg_create_widget() and gbaudio_tplg_process_kcontrols() has a specially error handle to cleanup. So it should be better to cleanup 'control' when fails.

commit a44f9d6f9dc1fb314a3f1ed2dcd4fbbcc3d9f892 upstream. There is a wrong comparison of the total size of the loaded firmware css->fw->size with the size of a pointer to struct imgu_fw_header. Turn binary_header into a flexible-array member[1][2], use the struct_size() helper and fix the wrong size comparison. Notice that the loaded firmware needs to contain at least one 'struct imgu_fw_info' item in the binary_header[] array. It's also worth mentioning that "css->fw->size < struct_size(css->fwp, binary_header, 1)" with binary_header declared as a flexible-array member is equivalent to "css->fw->size < sizeof(struct imgu_fw_header)" with binary_header declared as a one-element array (as in the original code). The replacement of the one-element array with a flexible-array member also helps with the ongoing efforts to globally enable -Warray-bounds and get us closer to being able to tighten the FORTIFY_SOURCE routines on memcpy().

commit a23461c47482fc232ffc9b819539d1f837adf2b1 upstream. The driver uses endpoint-sized USB transfer buffers but up until recently had no sanity checks on the sizes. Commit e1f13c879a7c ("staging: comedi: check validity of wMaxPacketSize of usb endpoints found") inadvertently fixed NULL-pointer dereferences when accessing the transfer buffers in case a malicious device has a zero wMaxPacketSize. Make sure to allocate buffers large enough to handle also the other accesses that are done without a size check (e.g. byte 18 in vmk80xx_cnt_insn_read() for the VMK8061_MODEL) to avoid writing beyond the buffers, for example, when doing descriptor fuzzing. The original driver was for a low-speed device with 8-byte buffers. Support was later added for a device that uses bulk transfers and is presumably a full-speed device with a maximum 64-byte wMaxPacketSize.
