| H A D | Kconfig | 357b41ca Sat Feb 15 08:45:56 CST 2020 Matthieu Baerts <matthieu.baerts@tessares.net> mptcp: select CRYPTO
Without this modification and if CRYPTO is not selected, we have this
warning:
WARNING: unmet direct dependencies detected for CRYPTO_LIB_SHA256
Depends on [n]: CRYPTO [=n]
Selected by [y]:
- MPTCP [=y] && NET [=y] && INET [=y]
MPTCP selects CRYPTO_LIB_SHA256 which seems to depend on CRYPTO. CRYPTO
is now selected to avoid this issue.
Even though the config system prints that warning, it looks like
sha256.c is compiled and linked even without CONFIG_CRYPTO. Since MPTCP
will end up needing CONFIG_CRYPTO anyway in future commits -- currently
in preparation for net-next -- we propose to add it now to fix the
warning.
The dependency in the config system comes from the fact that
CRYPTO_LIB_SHA256 is defined in "lib/crypto/Kconfig" which is sourced
from "crypto/Kconfig" only if CRYPTO is selected.
Fixes: 65492c5a6ab5 (mptcp: move from sha1 (v0) to sha256 (v1))
