Create a script for comparing tcrypt speed test logs. The script will systematically analyze differences item by item and provide a summary (average). This tool is useful for evaluating the stability of cryptographic module algorithms and assisting with performance optimization. Please note that for such a comparison, stability depends on whether we allow frequency to float or pin the frequency. The script produces comparisons in two scenes: 1. For operations in seconds ================================================================================ rfc4106(gcm(aes)) (pcrypt(rfc4106(gcm_base(ctr(aes-generic),ghash-generic)))) encryption -------------------------------------------------------------------------------- bit key | byte blocks | base ops | new ops | differ(%) 160 | 16 | 66439 | 63063 | -5.08 160 | 64 | 62220 | 57439 | -7.68 ... 288 | 4096 | 15059 | 16278 | 8.09 288 | 8192 | 9043 | 9526 | 5.34 -------------------------------------------------------------------------------- average differ(%s) | total_differ(%) -------------------------------------------------------------------------------- 5.70 | -4.49 ================================================================================ 2.

Provide an option in Inline IPsec configure mailbox to configure the CPT_AF_LFX_CTL:CTX_ILEN for inline CPT LF attached to CPT RVU PF. This is needed to set the ctx ilen to size of inbound SA for HW errata IPBUCPT-38756. Not setting this would lead to new context's not being fetched. Also set FLR_FLUSH in CPT_LF_CTX_CTL for CPT LF's as workaround for same errata. Signed-off-by:

On CN10KA B0/CN10KB, CPT scatter gather format has modified to support multi-seg in inline IPsec. Due to this CPT requires new firmware and doesn't work with CN10KA0/A1 firmware. To make HW works in backward compatibility mode or works with CN10KA0/A1 firmware, a bit(T106_MODE) is introduced in HW CSR. This patch adds devlink parameter for configuring T106_MODE. This patch also documents the devlink parameter under Documentation/crypto/device_drivers. Signed-off-by:

smatch warnings: drivers/crypto/stm32/stm32-crc32.c:108 stm32_crc_get_next_crc() warn: can 'crc' even be NULL? Use list_first_entry_or_null instead of list_first_entry to retrieve the first device registered. The function list_first_entry always return a non NULL pointer even if the list is empty. Hence checking if the pointer returned is NULL does not tell if the list is empty or not. Reported-by:

When moved, functions and defines have been renamed from 4XXX to GEN4. Code specific to the device is moved to the file adf_gen4_hw_data.c.

When the mpi_ec_ctx structure is initialized, some fields are not cleared, causing a crash when referencing the field when the structure was released. Initially, this issue was ignored because memory for mpi_ec_ctx is allocated with the __GFP_ZERO flag. For example, this error will be triggered when calculating the Za value for SM2 separately.

The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is ignored (apart from emitting a warning) and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new(), which already returns void. Eventually after all drivers are converted, .remove_new() will be renamed to .remove(). Trivially convert this driver from always returning zero in the remove callback to the void returning variant. Signed-off-by:
