crypto: user - make NETLINK_CRYPTO work inside netns
Currently, NETLINK_CRYPTO works only in the init network namespace. It doesn't make much sense to cut it out of the other network namespaces, so do the minor plumbing work necessary to make it work in any network namespace. Code inspired by net/core/sock_diag.c. Tested using kcapi-dgst from libkcapi [1]: Before: # unshare -n kcapi-dgst -c sha256 </dev/null | wc -c libkcapi - Error: Netlink error: sendmsg failed libkcapi - Error: Netlink error: sendmsg failed libkcapi - Error: NETLINK_CRYPTO: cannot obtain cipher information for hmac(sha512) (is required crypto_user.c patch missing? see documentation) 0 After: # unshare -n kcapi-dgst -c sha256 </dev/null | wc -c 32 [1] https://github.com/smuellerDD/libkcapi Signed-off-by: Ondrej Mosnacek <omosnace@redhat.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
