This part is false.
Tested with:
- server: centos 6.5, rudder 4.3.10 (system open ssl: 1.0.1e-fips)
- agent: centos 7.6, rudder 5.0.15-nightly, (embedded openssl 1.1.1 and 1.1.0 (???), system openssl 1.0.2k-fips)
For the embeded version, not sure how to get it. ldd links to our own lib (/opt/rudder/bin/libssl.so.1.1), but strings say:
OPENSSL_1_1_0
OPENSSL_1_1_0d
OPENSSL_1_1_1
OPENSSL_1_1_1a
OPENSSL_1_1_0i
OPENSSL_1_1_0f

/opt/rudder/bin/openssl version gives the embedded version number

Closing this one as the problem is not present in any rudder supported version anymore - we have better things to do than loose time on it. Still, it's very sad that we were not able to make that documentation straight when the need was present for our users. |
