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.

Call trace will appear in the Hisilicon crypto driver unbinding or disabling SRIOV during task running with TFMs on the corresponding function.

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:

Current minimum required version of binutils is 2.23, which supports CRC32 instruction mnemonic. Replace the byte-wise specification of CRC32 with this proper mnemonic. The compiler is now able to pass memory operand to the instruction, so there is no need for a temporary register anymore. Some examples of the improvement: 12a: 48 8b 08 mov (%rax),%rcx 12d: f2 48 0f 38 f1 f1 crc32q %rcx,%rsi 133: 48 83 c0 08 add $0x8,%rax 137: 48 39 d0 cmp %rdx,%rax 13a: 75 ee jne 12a <crc32c_intel_update+0x1a> to: 125: f2 48 0f 38 f1 06 crc32q (%rsi),%rax 12b: 48 83 c6 08 add $0x8,%rsi 12f: 48 39 d6 cmp %rdx,%rsi 132: 75 f1 jne 125 <crc32c_intel_update+0x15> and: 146: 0f b6 08 movzbl (%rax),%ecx 149: f2 0f 38 f0 f1 crc32b %cl,%esi 14e: 48 83 c0 01 add $0x1,%rax 152: 48 39 d0 cmp %rdx,%rax 155: 75 ef jne 146 <crc32c_intel_update+0x36> to: 13b: f2 0f 38 f0 02 crc32b (%rdx),%eax 140: 48 83 c2 01 add $0x1,%rdx 144: 48 39 ca cmp %rcx,%rdx 147: 75 f2 jne 13b <crc32c_intel_update+0x2b> As the compiler has some more freedom w.r.t. register allocation, there is also a couple of reg-reg moves removed. There are no hidden states for CRC32 insn, so there is no need to mark assembly as volatile. v2: Introduce CRC32_INST define. Signed-off-by:

This patch fixes most sparse warnings in the cesa driver. The only ones remaining are to do with copying data between iomem pointers and SG lists. Most changes are trivial. The following are the noteworthy ones: - Removal of swab in mv_cesa_aes_setkey. This appears to be bogus as everything gets swabbed again later on so for BE this ends up being different from LE. The change takes the LE behaviour as the correct one. - next_dma in mv_cesa_tdma_chain was not swabbed. Signed-off-by:

The header file algapi.h includes skbuff.h unnecessarily since all we need is a forward declaration for struct sk_buff. This patch removes that inclusion. Unfortunately skbuff.h pulls in a lot of things and drivers over the years have come to rely on it so this patch adds a lot of missing inclusions that result from this. Signed-off-by:

General fixes too, and a lot of them marked for stable. Lastly, a bit of fallout from the async buffered reads, where we now more easily trigger short reads.
