Herbert,
I have compile issues with crypto_shash interfaces, no such issues
with crypto_hash_ APIs,
everything works fine.
When I have code like this, I have errors and warning and when I cast
them as (char *), module
oopses.
struct session_key {
unsigned int len;
union {
char ntlm[CIFS_SESS_KEY_SIZE + 16];
char krb5[CIFS_SESS_KEY_SIZE + 16]; /* BB: length correct? */
struct {
char key[16];
struct ntlmv2_resp resp;
} ntlmv2;
} data;
};
if (server->secType == RawNTLMSSP)
crypto_shash_update(&desc, server->session_key.data.ntlmv2.key,
CIFS_NTLMV2_SESSKEY_SIZE);
else
crypto_shash_update(&desc, server->session_key.data,
<----
server->session_key.len);
And
len = cifs_strtoUCS((__le16 *)user, ses->userName, len, nls_cp);
UniStrupr(user);
crypto_shash_update(&desc, user, 2 * len);
<----
No such issues and oops with crypto_hash_APIs.
