speidy 8effc09ab7 common: ssl_calls: check if SSL object created right after its creation. 2018-03-21 08:16:12 +02:00

common: temporarily disable DHE
until make it possible to use generated DH parameters per installation.

common: obey coding style, remove trailing space 2018-03-01 12:11:52 +09:00
Enrico Tagliavini 70b5adb396 add support for DHE ciphers via compiled in dhparam
make it possible to use regular (non EC) EDH ciphers. To make this
possible a Diffie-Hellman parameter must be passed to the openssl
library. There are a few options possible as described in the manuals at
[1] and [2]. Simplest approach is to generate a DH parameter using
openssl dhparam -C <lenght> and include the code into the application.
The lenght used for this commit is 2236 bits long, which is the longest
possible without risking backward incompatibilities with old systems as
stated in [1]. Newer systems should use ECDH anyway, so it makes sense
to keep this method as compatible with older system as possible.
Paramters longer than 2048 should still be secure enough at the time of
writing.

Enrico Tagliavini 6cdc0f31b0 enable automatic ECDH when possible (openssl 1.0.2)
Openssl 1.1.0 and later are enabling ECDH automatically, but for older
version it must be enabled explicitly or all Perfect Forward Secrecy
ciphers will be silently ignored. See also [1]. This commit applies the
same fix as found in CnetOS 7 httpd package to enable automatic ECDH as
found in [2].

common: quit using `!` as comment out symbol in config files
It is not used anywhere in default config. Some config like
`tls_ciphers` might contain `!` like this:

    tls_ciphers=FIPS:!aNULL:!eNULL

Fixes #1033.

Koichiro IWAO d0c27a2904 common: suppress log when closing log files
because if xrdp is running 'fork=yes' mode, the log message
'shutting down log subsystem...' is logged everytime when the child
process is exitting. In other words, everytime when clients are
disconnecting.  This is a little bit too vebose.

Koichiro IWAO 65c1fe87d7 Log user-friendly message when certificate/privkey is inaccessible
We shouldn't assume that xrdp daemon is running under root privilege.
In many cases, root privilege is not really needed for xrdp daemon.
xrdp may fail to load certificate/privkey due to lack of permissions
when running under user privilege. Checking existence of files is not
enough and xrdp should output user-friendly log in such case.
