[PATCH v3 0/6] media: ti, cdns: Multiple pixel support and misc fixes

by Jai Luthra

Hi, The first four patches in this series are miscellaneous fixes and improvements in the Cadence and TI CSI-RX drivers around probing, fwnode and link creation. The last two patches add support for transmitting multiple pixels per clock on the internal bus between Cadence CSI-RX bridge and TI CSI-RX wrapper. As this internal bus is 32-bit wide, the maximum number of pixels that can be transmitted per cycle depend upon the format's bit width. Secondly, the downstream element must support unpacking of multiple pixels. Thus we export a module function that can be used by the downstream driver to negotiate the pixels per cycle on the output pixel stream of the Cadence bridge.

[PATCH] clk: qcom: tcsrcc-x1e80100: Set the bi_tcxo as parent to eDP refclk

by Abel Vesa

All the other ref clocks provided by this driver have the bi_tcxo as parent. The eDP refclk is the only one without a parent, leading to reporting its rate as 0. So set its parent to bi_tcxo, just like the rest of the refclks.

[PATCH] mm: Fix possible deadlock in console_trylock_spinning

by Gu Bowen

kmemleak_scan_thread() invokes scan_block() which may invoke a nomal printk() to print warning message. This can cause a deadlock in the scenario reported below: CPU0 CPU1 ---- ---- lock(kmemleak_lock); lock(&port->lock); lock(kmemleak_lock); lock(console_owner); To solve this problem, switch to printk_safe mode before printing warning message, this will redirect all printk()-s to a special per-CPU buffer, which will be flushed later from a safe context (irq work), and this deadlock problem can be avoided. Our syztester report the following lockdep error: ====================================================== WARNING: possible circular locking dependency detected 5.10.0-22221-gca646a51dd00 #16 Not

This issue was introduced by commit f85d39dd7ed8 ("kcov, usb: disable interrupts in kcov_remote_start_usb_softirq"). However, this creates a conflict on PREEMPT_RT kernels. The local_irq_save() call establishes an atomic context where sleeping is forbidden. Inside this context, kcov_remote_start() is called, which on PREEMPT_RT uses sleeping locks (spinlock_t and local_lock_t are mapped to rt_mutex). This results in a sleeping function called from invalid context. On PREEMPT_RT, interrupt handlers are threaded, so the re-entrancy scenario is already safely handled by the existing local_lock_t and the global kcov_remote_lock within kcov_remote_start(). Therefore, the outer local_irq_save() is not necessary. This preserves the intended re-entrancy protection for non-RT kernels while resolving the locking violation on PREEMPT_RT kernels. After making this modification and testing it, syzkaller fuzzing the PREEMPT_RT kernel is now running without stopping on latest announced Real-time Linux.

[PATCH] HID: multitouch: fix integer overflow in set_abs()

by Qasim Ijaz

It is possible for a malicious HID device to trigger a signed integer overflow (undefined behaviour) in set_abs() in the following expression by supplying bogus logical maximum and minimum values: int fuzz = snratio ? (fmax - fmin) / snratio : 0; For example, if the logical_maximum is INT_MAX and logical_minimum is -1 then (fmax - fmin) resolves to INT_MAX + 1, which does not fit in a 32-bit signed int, so the subtraction overflows. Fix this by computing the difference in a 64 bit context.

[PATCH] riscv: Only allow LTO with CMODEL_MEDANY

by Nathan Chancellor

When building with CONFIG_CMODEL_MEDLOW and CONFIG_LTO_CLANG, there is a series of errors due to some files being unconditionally compiled with '-mcmodel=medany', mismatching with the rest of the kernel built with '-mcmodel=medlow': ld.lld: error: Function Import: link error: linking module flags 'Code Model': IDs have conflicting values: 'i32 3' from vmlinux.a(init.o at 899908), and 'i32 1' from vmlinux.a(net-traces.o at 1014628) Only allow LTO to be performed when CONFIG_CMODEL_MEDANY is enabled to ensure there will be no code model mismatch errors. An alternative solution would be disabling LTO for the files with a different code model than the main kernel like some specialized areas of the kernel do but doing that for individual files is not as sustainable than forbidding the combination altogether.

[PATCH 1/3] KEYS: trusted_tpm1: Compare HMAC values in constant time

by Eric Biggers

To prevent timing attacks, HMAC value comparison needs to be constant time. Replace the memcmp() with the correct function, crypto_memneq().
