[pve-devel] [PATCH http-server/manager/pmg-api/docs 0/10] expose more TLS knobs

[pve-devel] [PATCH http-server/manager/pmg-api/docs 0/10] expose more TLS knobs

[Fabian Grünbichler]

this series adds the following options to /etc/default/$proxy, and
corresponding handling in pveproxy/pmgproxy/api-server:

- TLS 1.3 ciphersuites (these are different to < 1.3 cipher lists)
- disable TLS 1.2 / disable TLS 1.3 option (rest are disabled by default
  anyway)
- alternative location for pveproxy-ssl.key outside of /etc/pve (PVE
  only)

while not strictly required, it probably makes sense to add a/bump the
versioned dep from pve-manager/pmg-api to patched
libpve-http-server-perl - nothing should break, but the new options are
only handled if both packages are updated.

[pve-devel] [PATCH http-server 1/3] fix #3790: allow setting TLS 1.3 cipher suites

[Fabian Grünbichler]

like the TLS <= 1.2 cipher list, but needs a different option since the
format and values are incompatible. AnyEvent doesn't yet handle this
directly like the cipher list, so set it directly on the context.

requires corresponding patch in pve-manager (which reads the config, and
passes relevant parts back to the API server).

Re: [pve-devel] [PATCH http-server 1/3] fix #3790: allow setting TLS 1.3 cipher suites

[Stoiko Ivanov]

Thanks for tackling this!
gave it a spin - works as advertised

one thing I think could be improved - is that currently nothing is logged
when CIPHERSUITES is set to an invalid setting.
(tested with "garbage TLS_CHACHA20_POLY1305_SHA256")

with TLS1.2 CIPHERS the log gets filled with:
'garbage' was not accepted as a valid cipher list by AnyEvent::TLS at /usr/share/perl5/PVE/APIServer/AnyEvent.pm line 1913.

The handling of openssl seems kinda sane[0] (fallback to the default list
if the provided one is not recognized) - so I think simply a 
syslog('warn', - might help as feedback to users
(quickly tested it - Net::SSLeay::CTX_set_ciphersuites returns '0' if it
did not set the list).

[Fabian Grünbichler]

SSL 2 and 3 are already disabled by default by us, and TLS 1.1 and below
are disabled by default on Debian systems.

requires corresponding patch in pve-manager to have an effect.
