The pci bdf number check is added for qos written by using the pci api. Directly get the devfn by pci_dev, so delete some redundant code. And use the kstrtoul instead of sscanf to simplify code. Signed-off-by:

Increase the buffer to prevent stack overflow by fuzz test. The maximum length of the qos configuration buffer is 256 bytes. Currently, the value of the 'val buffer' is only 32 bytes. The sscanf does not check the dest memory length. So the 'val buffer' may stack overflow. Signed-off-by:

We want to leverage keyring to store sensitive keys, and then use those keys for symmetric encryption via the crypto API. Among the key types we wish to support are: user, logon, encrypted, and trusted. User key types are already able to have their data copied to user space, but logon does not support this. Further, trusted and encrypted keys will return their encrypted data back to user space on read, which does not make them ideal for symmetric encryption. To support symmetric encryption for these key types, add a new ALG_SET_KEY_BY_KEY_SERIAL setsockopt() option to the crypto API. This allows users to pass a key_serial_t to the crypto API to perform symmetric encryption. The behavior is the same as ALG_SET_KEY, but the crypto key data is copied in kernel space from a keyring key, which allows for the support of logon, encrypted, and trusted key types. Keyring keys must have the KEY_(POS|USR|GRP|OTH)_SEARCH permission set to leverage this feature. This follows the asymmetric_key type where key lookup calls eventually lead to keyring_search_rcu() without the KEYRING_SEARCH_NO_CHECK_PERM flag set. Signed-off-by:

The RK3399 has 2 rk3288 compatible crypto device named crypto0 and crypto1. The only difference is lack of RSA in crypto1. We need to add driver support for 2 parallel instance as only one need to register crypto algorithms. Then the driver will round robin each request on each device. For avoiding complexity (device bringup after a TFM is created), PM is modified to be handled per request. Signed-off-by:

Add the number of clocks needed for each compatible. Rockchip's datasheet give maximum frequencies for some clocks, so add checks for verifying they are within limits. Let's start with rk3288 for clock frequency check, other will came later. Signed-off-by:

The stm32_rng_read() function samples TRNG by 4 bytes until at least 5 bytes are free in the input buffer. The last four bytes are never read. For example, 60 bytes are returned in case the input buffer size is 64 bytes. Read until at least 4 bytes are free in the input buffer. Fill the buffer entirely in case the buffer size is divisible by 4. Cc: Oleg Karfich <oleg.karfich@wago.com> Signed-off-by:

The stm32_rng_read() function uses `retval` variable as a counter of generated random bytes. However, the same variable is used to store a result of the polling function in case the driver is waiting until the TRNG is ready. The TRNG generates random numbers by 16B. One loop read 4B. So, the function calls the polling every 16B, i.e. every 4th loop. The `retval` counter is reset on poll call and only number of bytes read after the last poll call is returned to the caller. The remaining sampled random bytes (for example 48 out of 64 in case 64 bytes are read) are not used. Use different variable to store the polling function result and do not overwrite `retval` counter. Cc: Oleg Karfich <oleg.karfich@wago.com> Signed-off-by:
