mod_measure_process: Report the enforced limit The soft limit is what the kernel actually enforces, while the hard limit is is how far you can change the soft limit without privileges. Unless the process dynamically adjusts the soft limit, knowing the hard limit is not as useful as knowing the soft limit. Reporting the soft limit and the number of in-use FDs allows placing alerts on expressions like 'process_open_fds / process_max_fds >= 0.95'

summary: Fingerprint based s2s authentication

Introduction
============

This module allows you to manually pin certificate fingerprints of
remote servers.

Details
=======

Servers not listed in the configuration are not affected.

Configuration
=============

After installing and enabling this module, you can put fingerprints of
remote servers in your config like this:

``` {.lua}
s2s_auth_fingerprint_digest = "sha1" -- This is the default. Other options are "sha256" and "sha512"
s2s_trusted_fingerprints = {
    ["jabber.org"] = "11:C2:3D:87:3F:95:F8:13:F8:CA:81:33:71:36:A7:00:E0:01:95:ED";
    ["matthewwild.co.uk"] = {
        "FD:7F:B2:B9:4C:C4:CB:E2:E7:48:FB:0D:98:11:C7:D8:4D:2A:62:AA";
        "CF:F3:EC:43:A9:D5:D1:4D:D4:57:09:55:52:BC:5D:73:06:1A:A1:A0";
    };
}

-- If you don't want to fall back to dialback, you can list the domains s2s_secure_domains too
s2s_secure_domains = {
    "jabber.org";
}
```
