Function definitions in headers are usually marked as 'static inline'.
Since 'inline' is missing for crypto_reportstat(), if it were not
referenced from a .c file that includes this header, it would produce
a warning.
Also, 'struct crypto_user_alg' is not declared in this header.
I included <linux/crytouser.h> instead of adding the forward declaration
as suggested [1].
Detected by compile-testing this header as a standalone unit:
./include/crypto/internal/cryptouser.h:6:44: warning: ‘struct crypto_user_alg’ declared inside parameter list will not be visible outside of this definition or declaration
struct crypto_alg *crypto_alg_match(struct crypto_user_alg *p, int exact);
^~~~~~~~~~~~~~~
./include/crypto/internal/cryptouser.h:11:12: warning: ‘crypto_reportstat’ defined but not used [-Wunused-function]
static int crypto_reportstat(struct sk_buff *in_skb, struct nlmsghdr *in_nlh, struct nlattr **attrs)

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

Move the declaration of crypto_nlsk into internal/cryptouser.h. This
fixes the following sparse warning:
crypto/crypto_user_base.c:41:13: warning: symbol 'crypto_nlsk' was not declared. Should it be static?

This patch removes unused dump functions for crypto_user_stats.
There are remains of the copy/paste of crypto_user_base to
crypto_user_stat and I forgot to remove them.

Even if CRYPTO_STATS is set to n, some part of CRYPTO_STATS are
compiled.
This patch made all part of crypto_user_stat uncompiled in that case.

This patch implement a generic way to get statistics about all crypto
usages.
