Firmware update: Asuswrt-Merlin 380.57

Asus uses Tomato-derived firmware called Asuswrt for its newer routers, such as the RT-AC66U and RT-AC87U. This firmware is, with the exception of a few drivers, open source, whereby the closed binaries are included. Asuswrt-merlin, in turn, is a modified version of the original firmware from Asus. It includes bug fixes and minor improvements, but still tries to stay close to the original, so that it remains possible to add new features that Asus introduces to the code. Version 380.57 has been released and the following changes and improvements have been made to it:

New:

• Merged with 380_1031 GPL
• Added RT-AC3100 and RT-AC5300 support
• Added RT-AC68U HW Revision C1 support
• Backup/Restore of the content of the JFFS partition (under Administration Restore/Save Settings)
• Added DNSSEC support. Can be enabled under LAN -> DHCP.
• Added custom/postconf support for igmpproxy.conf.

Changed:

• Increased user account limit from 16 to 32 on the VPN server pages.
• Updated e2fsprogs to 1.42.13
• Increased maximum entries in Parental Control (time scheduler) to 32.
• Updated miniupnpd to 1.9.20151119.
• Updated Openssl to 1.0.2e.
• Downgraded Dropbear to 2014.66, too many issues in the newer releases.
• Improvements to VPN Status page

Fixed:

• CTF not automatically disabled when enabling IPTraffic.
• Openvpn clients 3 through 5 were all run on the first CPU core. They are now properly alternated like the first two (odd on CPU1, even on CPU0)
• smb.log generated by networkmap could fill up RAM
• upnpc_xml.log generated by miniupnpc could fill up RAM
• Inconsistent names used on IPTraffic and Sysinfo page. Now, we give priority to any description manually entered on the networkmap, followed by static hostname, then any current (lease) hostname.
• MAC queries sent to the OUI database were broken due to changes on the IEEE website
• Applying changes to OpenVPN client page would start the client even if it was disabled/stopped.
