crypto: hisilicon/qm - disable error report before flr

2026-07-24T14:19:24+00:00

[ Upstream commit e71dc5602b9a29027f6aedd5990d3e8c4f638c8c ] Before function level reset, driver first disable device error report and then waits for the device reset to complete. However, when the error is recovered, the error bits will be enabled again, resulting in invalid disable. It is modified to detect that there is no error before disable error report, and then do FLR.

crypto: hisi-trng - Remove crypto_rng interface

2026-07-18T14:55:40+00:00

commit 216a7795ec210bdabd5dad42323eee70bbfc8d90 upstream. drivers/crypto/hisilicon/trng/trng.c exposes the same hardware through two completely separate interfaces, crypto_rng and hwrng. However, the implementation of this is buggy because it permits generation operations from these interfaces to run concurrently with each other, accessing the same registers. That is, hisi_trng_generate() synchronizes with itself but not with hisi_trng_read(). This results in potential repetition of output from the RNG, output of non-random values, etc. Fortunately, there's actually no point in hardware RNG drivers implementing the crypto_rng interface. It's not actually used by anything besides the "rng" algorithm type of AF_ALG, which in turn is not actually used in practice. Other crypto_rng hardware drivers are likewise being phased out, leaving just the hwrng support. Thus, remove it to simplify the code and avoid conflict (and confusion) with the hwrng interface which is the one that actually matters.

crypto: hisilicon - Fix dma_unmap_single() direction

2026-04-12T08:46:29+00:00

The direction used to map the buffer skreq->iv is DMA_TO_DEVICE but it is unmapped with direction DMA_BIDIRECTIONAL in the error path. Change the unmap to match the mapping.

crypto: hisilicon - remove unused and non-public APIs for qm and sec

2026-04-12T08:46:29+00:00

- sec_register_to_crypto() and sec_unregister_from_crypto() have been removed, the function declarations have not been removed. Remove them. - hisi_qm_start_qp and hisi_qm_stop_qp are called internally by the QM. Therefore, the EXPORT_SYMBOL_GPL declaration of these non-public interfaces is deleted.

crypto: hisilicon - fix the format string type error

2026-04-12T08:46:28+00:00

1. The return value val of sec_debugfs_atomic64_get is of the u64 type, but %lld instead of %llu is used in DEFINE_DEBUGFS_ATTRIBUTE. Fix it. 2. In debugfs.c, since the types of q_depth and xeq_depth are u16, the results of q_depth - 1 and xeq_depth - 1 are int rather than u16. Use %d for int.

crypto: hisilicon/sec2 - prevent req used-after-free for sec

2026-03-27T09:52:44+00:00

During packet transmission, if the system is under heavy load, the hardware might complete processing the packet and free the request memory (req) before the transmission function finishes. If the software subsequently accesses this req, a use-after-free error will occur. The qp_ctx memory exists throughout the packet sending process, so replace the req with the qp_ctx.
