15 handle
16 [in] cipher handle
17
18 iniov
19 [in] head of scatter-gather list array holding the plaintext
20
21 outiov
22 [out] head of scatter-gather list of the destination buffers filled
23 with ciphertext
24
25 iovlen
26 [in] number of scatter-gather list entries
27
28 access
29 [in] kernel access type (KCAPI_ACCESS_HEURISTIC - use internal
30 heuristic for fastest kernel access; KCAPI_ACCESS_VMSPLICE - use
31 vmsplice access; KCAPI_ACCESS_SENDMSG - sendmsg access)
32
34 The individual scatter-gather list entries are processed with separate
35 invocations of the the given cipher.
36
37 The memory should be aligned at the page boundary using
38 posix_memalign(sysconf(_SC_PAGESIZE)), If it is not aligned at the page
39 boundary, the vmsplice call may not send all data to the kernel.
40
41 return number of bytes verify upon success; a negative errno-style
42 error code if an error occurred
