crypto: ccp - Fix incorrect payload size calculation in psp_poulate_hsti()

2025-09-13T04:11:05Z

payload_size field of the request header is incorrectly calculated using sizeof(req). Since 'req' is a pointer (struct hsti_request *), sizeof(req) returns the size of the pointer itself (e.g., 8 bytes on a 64-bit system), rather than the size of the structure it points to. This leads to an incorrect payload size being sent to the Platform Security Processor (PSP), potentially causing the HSTI query command to fail. Fix this by using sizeof(*req) to correctly calculate the size of the struct hsti_request. Signed-off-by: Yunseong Kim Reviewed-by: Mario Limonciello (AMD) > --- Signed-off-by: Herbert Xu

crypto: ccp - Fix typo in psp_populate_hsti function name

2025-08-22T09:28:44Z

The function "psp_poulate_hsti" was misspelled. This patch corrects the typo to "psp_populate_hsti" in both the function definition and its call site within psp_init_hsti(). Signed-off-by: Yunseong Kim Reviewed-by: Mario Limonciello > --- Signed-off-by: Herbert Xu

crypto: ccp - Remove redundant __GFP_ZERO

2025-08-16T09:24:31Z

Remove the redundant __GFP_ZERO flag from kzalloc() since kzalloc() inherently zeroes memory. Signed-off-by: Qianfeng Rong Reviewed-by: Mario Limonciello Signed-off-by: Herbert Xu

crypto: ccp - Move message about TSME being enabled later in init

2024-06-07T11:46:39Z

Some of the security attributes data is now populated from an HSTI command on some processors, so show the message after it has been populated. Signed-off-by: Mario Limonciello Acked-by: Tom Lendacky Signed-off-by: Herbert Xu

crypto: ccp - Add support for getting security attributes on some older systems

2024-06-07T11:46:39Z

Older systems will not populate the security attributes in the capabilities register. The PSP on these systems, however, does have a command to get the security attributes. Use this command during ccp startup to populate the attributes if they're missing.

crypto: ccp - Move security attributes to their own file

To prepare for other code that will manipulate security attributes move the handling code out of sp-pci.c. No intended functional changes. Signed-off-by: Mario Limonciello Acked-by: Tom Lendacky Signed-off-by: Herbert Xu
