crypto: iaa - Use kmemdup() instead of kzalloc() and memcpy()

2024-05-10T09:15:25Z

Fixes the following two Coccinelle/coccicheck warnings reported by memdup.cocci: iaa_crypto_main.c:350:19-26: WARNING opportunity for kmemdup iaa_crypto_main.c:358:18-25: WARNING opportunity for kmemdup Signed-off-by: Thorsten Blum Reviewed-by: Tom Zanussi Signed-off-by: Herbert Xu

crypto: iaa - Use cpumask_weight() when rebalancing

2024-04-12T07:07:52Z

If some cpus are offlined, or if the node mask is smaller than expected, the 'nonexistent cpu' warning in rebalance_wq_table() may be erroneously triggered. Use cpumask_weight() to make sure we only iterate over the exact number of cpus in the mask. Also use num_possible_cpus() instead of num_online_cpus() to make sure all slots in the wq table are initialized. Signed-off-by: Tom Zanussi Signed-off-by: Herbert Xu

crypto: iaa - Change iaa statistics to atomic64_t

2024-04-02T02:49:38Z

Change all the iaa statistics to use atomic64_t instead of the current u64, to avoid potentially inconsistent counts. Signed-off-by: Tom Zanussi Signed-off-by: Herbert Xu

crypto: iaa - Add global_stats file and remove individual stat files

2024-04-02T02:49:38Z

Currently, the wq_stats output also includes the global stats, while the individual global stats are also available as separate debugfs files. Since these are all read-only, there's really no reason to have them as separate files, especially since we already display them as global stats in the wq_stats. It makes more sense to just add a separate global_stats file to display those, and remove them from the wq_stats, as well as removing the individual stats files.

crypto: iaa - Remove comp/decomp delay statistics

2024-04-02T02:49:38Z

As part of the simplification/cleanup of the iaa statistics, remove the comp/decomp delay statistics. They're actually not really useful and can be/are being more flexibly generated using standard kernel tracing infrastructure. Signed-off-by: Tom Zanussi Signed-off-by: Herbert Xu

crypto: iaa - fix decomp_bytes_in stats

2024-04-02T02:49:38Z

Decomp stats should use slen, not dlen. Change both the global and per-wq stats to use the correct value. Signed-off-by: Tom Zanussi Signed-off-by: Herbert Xu

crypto: iaa - Fix nr_cpus < nr_iaa case

2024-03-22T11:42:20Z

If nr_cpus < nr_iaa, the calculated cpus_per_iaa will be 0, which causes a divide-by-0 in rebalance_wq_table(). Make sure cpus_per_iaa is 1 in that case, and also in the nr_iaa == 0 case, even though cpus_per_iaa is never used if nr_iaa == 0, for paranoia.

crypto: iaa - fix the missing CRYPTO_ALG_ASYNC in cra_flags

2024-03-08T11:23:25Z

Add the missing CRYPTO_ALG_ASYNC flag since intel iaa driver works asynchronously. Signed-off-by: Barry Song Acked-by: Tom Zanussi Signed-off-by: Herbert Xu

crypto: iaa - Fix comp/decomp delay statistics

2024-03-01T10:35:40Z

The comp/decomp delay statistics currently have no callers; somehow they were dropped during refactoring. There originally were also two sets, one for the async algorithm, the other for the synchronous version. Because the synchronous algorithm was dropped, one set should be removed. To keep it consistent with the rest of the stats, and since there's no ambiguity, remove the acomp/adecomp versions. Also add back the callers.

crypto: iaa - Fix async_disable descriptor leak

2024-03-01T10:35:40Z

The disable_async paths of iaa_compress/decompress() don't free idxd descriptors in the async_disable case. Currently this only happens in the testcases where req->dst is set to null. Add a test to free them in those paths. Signed-off-by: Tom Zanussi Signed-off-by: Herbert Xu
