If the crypto4xx device is continuously loaded by dm-crypt and ipsec work, it will start to work intermittent after a few (between 20-30) seconds, hurting throughput and latency. This patch contains various stability improvements in order to fix this issue. So far, the hardware has survived more than a day without suffering any stalls under the continuous load. Signed-off-by:

This patch overhauls and fixes code related to crypto4xx_build_pd() * crypto4xx_build_pd() did not handle chained source scatterlist. This is fixed by replacing the buggy indexed-access of &src[idx] with sg_next() in the gather array setup loop. * The redundant is_hash, direction, save_iv and pd_ctl members in the crypto4xx_ctx struct have been removed. - is_hash can be derived from the crypto_async_request parameter. - direction is already part of the security association's bf.dir bitfield. - save_iv is unused. - pd_ctl always had the host_ready bit enabled anyway. (the hash_final case is rather pointless, since the ahash code has been deactivated). * make crypto4xx_build_pd()'s caller responsible for converting the IV to the LE32 format. * change crypto4xx_ahash_update() and crypto4xx_ahash_digest() to initialize a temporary destination scatterlist. This allows the removal of an ugly cast of req->result (which is a pointer to an u8-array) to a scatterlist pointer. * change crypto4xx_build_pd() return type to int. After all it returns -EINPROGRESS/-EBUSY. * fix crypto4xx_build_pd() thread-unsafe sa handling. Signed-off-by: -

The hardware expects that the keys, IVs (and inner/outer hashes) are in the le32 format. This patch changes all hardware interface declarations to use the correct LE32 data format for each field. In order to pass __CHECK_ENDIAN__ checks, crypto4xx_memcpy_le has to be honest about the endianness of its parameters. The function was split and moved to the common crypto4xx_core.h header. This allows the compiler to generate better code if the sizes/len is a constant (various *_IV_LEN). Please note that the hardware isn't consistent with the endiannes of the save_digest field in the state record struct though. The hashes produced by GHASH and CBC (for CCM) will be in LE32. Whereas md5 and sha{1/,256,...} do not need any conversion. Signed-off-by: -

Previously, If the crypto4xx driver used all available security contexts, it would simply refuse new requests with -EAGAIN. CRYPTO_TFM_REQ_MAY_BACKLOG was ignored. in case of dm-crypt.c's crypt_convert() function this was causing the following errors to manifest, if the system was pushed hard enough: | EXT4-fs warning (dm-1): ext4_end_bio:314: I/O error -5 writing to ino .. | EXT4-fs warning (dm-1): ext4_end_bio:314: I/O error -5 writing to ino .. | EXT4-fs warning (dm-1): ext4_end_bio:314: I/O error -5 writing to ino .. | JBD2: Detected IO errors while flushing file data on dm-1-8 | Aborting journal on device dm-1-8. | EXT4-fs error : ext4_journal_check_start:56: Detected aborted journal | EXT4-fs (dm-1): Remounting filesystem read-only | EXT4-fs : ext4_writepages: jbd2_start: 2048 pages, inode 498...; err -30 (This did cause corruptions due to failed writes) To fix this mess, the crypto4xx driver needs to notifiy the user to slow down. This can be achieved by returning -EBUSY on requests, once the crypto hardware was falling behind. Note: -EBUSY has two different meanings. Setting the flag CRYPTO_TFM_REQ_MAY_BACKLOG implies that the request was successfully queued, by the crypto driver. To achieve this requirement, the implementation introduces a threshold check and adds logic to the completion routines in much the same way as AMD's Cryptographic Coprocessor (CCP) driver do. Note2: Tests showed that dm-crypt starved ipsec traffic. Under load, ipsec links dropped to 0 Kbits/s. This is because dm-crypt's callback would instantly queue the next request. In order to not starve ipsec, the driver reserves a small portion of the available crypto contexts for this purpose. Signed-off-by:

If crypto4xx is used in conjunction with dm-crypt, the available ring buffer elements are not enough to handle the load properly. On an aes-cbc-essiv:sha256 encrypted swap partition the read performance is abyssal: (tested with hdparm -t) /dev/mapper/swap_crypt: Timing buffered disk reads: 14 MB in 3.68 seconds = 3.81 MB/sec The patch increases both PPC4XX_NUM_SD and PPC4XX_NUM_PD to 256. This improves the performance considerably: /dev/mapper/swap_crypt: Timing buffered disk reads: 104 MB in 3.03 seconds = 34.31 MB/sec Furthermore, PPC4XX_LAST_SD, PPC4XX_LAST_GD and PPC4XX_LAST_PD can be easily calculated from their respective PPC4XX_NUM_* constant.

The code is simplified by using two __be64 values for the operation instead of using two arrays of u8. This allows to get rid of the memory alignment code. In addition, the crypto_xor can be replaced with a native XOR operation. Finally, the definition of the variables is re-arranged such that the data structures come before simple variables to potentially reduce memory space. Signed-off-by:

If the algorithm we're parallelizing is asynchronous we might change CPUs between padata_do_parallel() and padata_do_serial(). However, we don't expect this to happen as we need to enqueue the padata object into the per-cpu reorder queue we took it from, i.e. the same-cpu's parallel queue. Ensure we're not switching CPUs for a given padata object by tracking the CPU within the padata object. If the serial callback gets called on the wrong CPU, defer invoking padata_reorder() via a kernel worker on the CPU we're expected to run on. Signed-off-by:

The reorder timer function runs on the CPU where the timer interrupt was handled which is not necessarily one of the CPUs of the 'pcpu' CPU mask set. Ensure the padata_reorder() callback runs on the correct CPU, which is one in the 'pcpu' CPU mask set and, preferrably, the next expected one. Do so by comparing the current CPU with the expected target CPU. If they match, call padata_reorder() right away. If they differ, schedule a work item on the target CPU that does the padata_reorder() call for us. Signed-off-by:

The parallel queue per-cpu data structure gets initialized only for CPUs in the 'pcpu' CPU mask set. This is not sufficient as the reorder timer may run on a different CPU and might wrongly decide it's the target CPU for the next reorder item as per-cpu memory gets memset(0) and we might be waiting for the first CPU in cpumask.pcpu, i.e. cpu_index 0. Make the '__this_cpu_read(pd->pqueue->cpu_index) == next_queue->cpu_index' compare in padata_get_next() fail in this case by initializing the cpu_index member of all per-cpu parallel queues. Use -1 for unused ones. Signed-off-by:

In 32-bit mode, the x86 architecture can hold full 32-bit pointers. Therefore, the code that copies the current address to the %ecx register and uses %ecx-relative addressing is useless, we could just use absolute addressing. The processors have a stack of return addresses for branch prediction. If we use a call instruction and pop the return address, it desynchronizes the return stack and causes branch prediction misses. This patch also moves the data to the .rodata section. Signed-off-by:

Add support to explicity ACK mailbox message because after sending message we can know the send status via error attribute of brcm_message. This is needed to support "txdone_ack" supported in mailbox controller driver. Fixes: 9d12ba86 ("crypto: brcm - Add Broadcom SPU driver") Signed-off-by:
