Remove redundant memzero_explicit() in sun8i_ss_cipher() before calling kfree_sensitive(). kfree_sensitive() will zero the memory with memzero_explicit(). Fixes: 453431a5 ("mm, treewide: rename kzfree() to kfree_sensitive()") Signed-off-by:

This patch fixes most of the sparse endianness warnings in stm32. The patch itself doesn't change anything apart from markings, but there is some questionable code in stm32_cryp_check_ctr_counter. That function operates on the counters as if they're in CPU order, however, they're then written out as big-endian. This looks like a genuine bug. Therefore I've left that warning alone until someone can confirm that this really does work as intended on little-endian. Signed-off-by: -

pm_runtime_get_sync() increments the runtime PM usage counter even when it returns an error code. However, users of cc_pm_get(), a direct wrapper of pm_runtime_get_sync(), assume that PM usage counter will not change on error. Thus a pairing decrement is needed on the error handling path to keep the counter balanced. Fixes: 8c7849a3 ("crypto: ccree - simplify Runtime PM handling") Signed-off-by:

This patch squashes all the sparse warnings in mediatek, some of which appear to be genuine bugs. In particular, previously on BE the keys and IVs all get 32-bit swabbed which can't be right because they don't get swabbed on LE. I presume LE is the one that actually works. Another funky thing is that the GHASH key gets swabbed on LE. This makes no sense but I'm presuming someone actually tested this on LE so I'm preserving the swabbing. Someone needs to test this though as it is entirely possible that GCM is the only thing that worked on BE but not LE. Signed-off-by: -

When the devices are removed or not existing, the corresponding algorithms which are registered by 'hisi-zip' driver can't be used. Move 'hisi_zip_register_to_crypto' from 'hisi_zip_init' to 'hisi_zip_probe'. The algorithms will be registered to crypto only when there is device bind on the driver. And when the devices are removed, the algorithms will be unregistered. In the previous process, the function 'xxx_register_to_crypto' need a lock and a static variable to judge if the registration is the first time. Move this action into the function 'hisi_qm_alg_register'. Each device will call 'hisi_qm_alg_register' to add itself to qm list in probe process and registering algs when the qm list is empty.

Since the drivers such as HPRE/SEC/ZIP do not implement 'pci_driver.shutdow', a RAS will be triggered at OS rebooting or shutting down as the hardware device is processing request. The log looks like this: NOTICE: [NimbusSecNodeType1]:[2372L]This is sec, Base = 0x141800000 NOTICE: [NimbusSecHandle]:[2319L] SecIntSt = 0x3 NOTICE: [NimbusSecHandle]:[2320L] SecQmIntStatus = 0x2 NOTICE: [PrintSecurityType]:[344L] SecurityType is RECOVERABLE! This patch offers a new API in qm to shutdown devices, and add shutdown callbacks in ACC driver based on this new API. So the running devices will be stopped when the OS reboot or shutdown.

Once the crypto hash walk is started by crypto_hash_walk_first() returning non-zero, crypto_hash_walk_done() must be called to unmap any memory which was mapped by *_walk_first(). Ensure crypto_hash_walk_done() is called properly by: 1) Re-arranging the check for device data to be prior to calling *_walk_first() 2) on error call crypto_hash_walk_done() with an error code to allow the hash walk code to clean up. While we are at it clean up the 'out' label to be more meaningful. Signed-off-by:

Currently the debugfs fops are defined in caam/intern.h. This causes problems because it creates identical static functions and variables in multiple files. It also creates warnings when those files don't use the fops. This patch moves them into a standalone file, debugfs.c. It also removes unnecessary uses of ifdefs on CONFIG_DEBUG_FS. Signed-off-by:

The current code waits for data to be available before attempting a second read. However the second read would not be executed as the while loop will exit. This fix does not wait if all data has been read (skips the call to msleep(0)) and reads a second time if partial data was retrieved on the first read. Worth noticing that since msleep(0) schedules a one jiffy timeout is better to skip such a call. Signed-off-by:
