Subject: Why does CRYPTO_USER require CAP_NET_ADMIN?
Date: Sat, 05 Apr 2014 16:43:44 +0200	[thread overview]
Message-ID: <534016A0.6020702@mirix.org> (raw)

If I'm not mistaken, CRYPTO_USER requires CAP_NET_ADMIN for all
requests. Is there any reason for this requirement for read-only requests?

I think read-only requests should not require CAP_NET_ADMIN. An example
where this is important is important is AF_ALG. I'm working on AF_ALG
support for GnuTLS, encryption and decryption via AF_ALG does not
require special capabilities. However, retrieving the cipher priority to
determine whether the cipher is hardware accelerated does require
CAP_NET_ADMIN.

Regards,
Matthias-Christian
