2021-04-21crypto: ccp: Use the stack for small SEV command buffersSean Christopherson1-73/+44
For commands with small input/output buffers, use the local stack to "allocate" the structures used to communicate with the PSP. Now that __sev_do_cmd_locked() gracefully handles vmalloc'd buffers, there's no reason to avoid using the stack, e.g. CONFIG_VMAP_STACK=y will just work.

2021-04-21crypto: ccp: Play nice with vmalloc'd memory for SEV command structsSean Christopherson2-5/+25
Copy the incoming @data comman to an internal buffer so that callers can put SEV command buffers on the stack without running afoul of CONFIG_VMAP_STACK=y, i.e. without bombing on vmalloc'd pointers. As of today, the largest supported command takes a 68 byte buffer, i.e. pretty much every command can be put on the stack. Because sev_cmd_mutex is held for the entirety of a transaction, only a single bounce buffer is required. Use the internal buffer unconditionally, as the majority of in-kernel users will soon switch to using the stack. At that point, checking virt_addr_valid() becomes (negligible) overhead in most cases, and supporting both paths slightly increases complexity. Since the commands are all quite small, the cost of the copies is insignificant compared to the latency of communicating with the PSP. Allocate a full page for the buffer as opportunistic preparation for SEV-SNP, which requires the command buffer to be in firmware state for commands that trigger memory writes from the PSP firmware. Using a full page now will allow SEV-SNP support to simply transition the page as needed.

2021-04-21crypto: ccp: Reject SEV commands with mismatching command bufferSean Christopherson1-2/+7
WARN on and reject SEV commands that provide a valid data pointer, but do not have a known, non-zero length. And conversely, reject commands that take a command buffer but none is provided (data is null). Aside from sanity checking input, disallowing a non-null pointer without a non-zero size will allow a future patch to cleanly handle vmalloc'd data by copying the data to an internal __pa() friendly buffer. Note, this also effectively prevents callers from using commands that have a non-zero length and are not known to the kernel. This is not an explicit goal, but arguably the side effect is a good thing from the kernel's perspective.

2021-04-21crypto: ccp: Detect and reject "invalid" addresses destined for PSPSean Christopherson1-0/+3
Explicitly reject using pointers that are not virt_to_phys() friendly as the source for SEV commands that are sent to the PSP. The PSP works with physical addresses, and __pa()/virt_to_phys() will not return the correct address in these cases, e.g. for a vmalloc'd pointer. At best, the bogus address will cause the command to fail, and at worst lead to system instability. While it's unlikely that callers will deliberately use a bad pointer for SEV buffers, a caller can easily use a vmalloc'd pointer unknowingly when running with CONFIG_VMAP_STACK=y as it's not obvious that putting the command buffers on the stack would be bad. The command buffers are relative small and easily fit on the stack, and the APIs to do not document that the incoming pointer must be a physically contiguous, __pa() friendly pointer.

2021-04-16crypto: qat - enable detection of accelerators hangWojciech Ziemba9-1/+99
Enable the detection of hangs by setting watchdog timers (WDTs) on generations that supports that feature. The default timeout value comes from HW specs. WTDs are reset each time an accelerator wins arbitration and is able to send/read a command to/from an accelerator. The value has added significant margin to make sure there are no spurious timeouts. The scope of watchdog is per QAT device. If a timeout is detected, the firmware resets the accelerator and returns a response descriptor with an appropriate error code.
