hwrng: omap - Fix probe error path cleanup

2026-07-05T05:27:15+00:00

omap_rng_probe() enables runtime PM before acquiring and enabling the functional clocks. Several later error paths returned or unwound without undoing all state acquired so far. If pm_runtime_resume_and_get() failed, the driver returned through the generic ioremap error label and left runtime PM enabled. If either clock lookup returned -EPROBE_DEFER, the function returned directly and skipped the runtime PM cleanup; the register clock defer path could also leave the already enabled functional clock prepared. Route these failures through the existing unwind labels so each path only undoes resources that were acquired successfully. Keep the resume failure path limited to pm_runtime_disable(), and use the later labels only after the runtime PM usage count or clocks have been acquired. This issue was identified during our ongoing static-analysis research while reviewing kernel code.

hwrng: xilinx-trng - propagate timeout before any data is read

2026-07-05T05:27:15+00:00

xtrng_readblock32() polls for 16-byte chunks but returns the number of bytes read even when the first poll times out. Its caller then treats a zero return as a short successful read, and partial reads for full 32-byte blocks can make the tail copy use a fixed block offset rather than the amount already produced. Return the poll error when no data has been read, preserve partial positive returns after some data is available, stop the generator on all collection exits, and append tail bytes at the current output count.

hwrng: qcom - Move qcom-rng.c into drivers/char/hw_random/

2026-07-05T05:22:35+00:00

Since this file just implements a hwrng driver, move it into drivers/char/hw_random/. Rename the kconfig option accordingly as well. Signed-off-by: Eric Biggers Signed-off-by: Herbert Xu

hwrng: atmel - drop __maybe_unused from atmel_trng_pm_ops

2026-07-05T05:19:52+00:00

Since atmel_trng_driver keeps atmel_trng_pm_ops referenced and pm_ptr() uses IS_ENABLED(), which allows the compiler to optimize away unused variables, drop the redundant __maybe_unused annotation. Signed-off-by: Thorsten Blum Signed-off-by: Herbert Xu

hwrng: core - fix rng list on registration error

2026-07-05T05:19:51+00:00

hwrng_register(rng) does the following: 1. Checks if rng has name and read methods set 2. Checks if the name already exists 3. Adds rng to global rng_list 4. May try to set rng to current_rng If step 4 fails, it returns an error. However, it does not remove the rng from rng_list, causing a dangling reference which can result in use-after-free if the caller frees rng, since registration failed. Add a list_del_init() cleanup step. Fixes: 2bbb6983887f ("hwrng: use rng source with best quality") Signed-off-by: Manos Pitsidianakis Signed-off-by: Herbert Xu

Replace by more specific (c files)

2026-07-03T05:38:17+00:00

Replace the #include of by the more specific where applicable. For most cases the include can be dropped completely, only a few drivers need one or two headers added.
