I've created a libnet-ssleay-perl package from version 18.6_6 but it
still hangs.
If someone wants to review my work it's here:
On the other hand, I hacked around in file
/usr/share/perl5/LWP/Protocol/http.pm. And, things seems to be working
better/ok when I move the
"if (defined($wbits) && $wbits =~ /[^\0]/) {...}
block before the
"if (defined($rbits) && $rbits =~ /[^\0]/) {...}
block around line 368: LWP::UserAgent->new->post returns the same
$response in the debuger when called with or without 'ssl_opts => {
SSL_version => "TLSv1_2"}' (though it doesn't return exactly the same
output on the terminal).
Here's the logs of y debug sessions:
