net: xfrm: Amend XFRMA_SEC_CTX nla_policy structure
[ Upstream commit d1e0e61d617ba17aa516db707aa871387566bbf7 ]
According to all consumers code of attrs[XFRMA_SEC_CTX], like
* verify_sec_ctx_len(), convert to xfrm_user_sec_ctx*
* xfrm_state_construct(), call security_xfrm_state_alloc whose prototype
is int security_xfrm_state_alloc(.., struct xfrm_user_sec_ctx *sec_ctx);
* copy_from_user_sec_ctx(), convert to xfrm_user_sec_ctx *
...
It seems that the expected parsing result for XFRMA_SEC_CTX should be
structure xfrm_user_sec_ctx, and the current xfrm_sec_ctx is confusing
and misleading (Luckily, they happen to have same size 8 bytes).
This commit amend the policy structure to xfrm_user_sec_ctx to avoid
ambiguity.
