OpenVPN is an open source VPN daemon
8353ae8075
By default OpenSSL 1.1+ only allows signatures and ecdh/ecdhx from the
default list of X25519:secp256r1:X448:secp521r1:secp384r1. In
TLS1.3 key exchange is independent from the signature/key of the
certificates, so allowing all groups per default is not a sensible
choice anymore and instead a shorter list is reasonable.
However, when using certificates with exotic curves that are not on
the group list, the signatures of these certificates will no longer
be accepted.
The tls-groups option allows to modify the group list to account
for these corner cases.
Patch V2: Uses local gc_arena instead of malloc/free, reword commit
message. Fix other typos/clarify messages
Patch V3: Style fixes, adjust code to changes from mbedTLS session
fix
Patch V5: Fix compilation with OpenSSL 1.0.2
Patch V6: Redo the 'while((token = strsep(&tmp_groups, ":"))' change
which accidentally got lost.
