kcapi_kpp_keygen_aio3
Generate a public key (asynchronous one shot)
Usage
ssize_t kcapi_kpp_keygen_aio(struct kcapi_handle * handle, struct iovec * outiov, size_t iovlen, int access);
Arguments
handle
[in] cipher handle
outiov
[out] head of scatter-gather list of the destination buffers filled with the generated public key
iovlen
[in] number of scatter-gather list entries
access
[in] kernel access type (KCAPI_ACCESS_HEURISTIC - use internal heuristic for fastest kernel access; KCAPI_ACCESS_VMSPLICE - use vmsplice access; KCAPI_ACCESS_SENDMSG - sendmsg access)
Overview
The individual scatter-gather list entries are processed with separate invocations of the the given cipher.
The memory should be aligned at the page boundary using posix_memalign(sysconf(_SC_PAGESIZE)), If it is not aligned at the page boundary, the vmsplice call may not send all data to the kernel.
return number of bytes verify upon success; a negative errno-style error code if an error occurred
