SafeSquid for Linux SWG safesquid-2017.1115.1800.3-swg-concept released

Improvements

1. Optimized TCP congestion control algorithm.
   Ensured implementation of TCP RENO for outgoing connections and TCP CUBIC for incoming connections.
2. Improvement in the data transfer speed.
   SafeSquid can now handle 10-15% more transactions per second. CPU and RAM utilization also decreased by almost 50%.
3. Logging improved to report the actual speed of data transfer.
   Example> debug: network: net_filebuf_read: speed: swgupdates2.safesquid.net 7082 bytes in 6.1520 ms [ 1.1512 MBps ]
   debug: network: net_transfer: speed: 192.168.0.12 downloaded from 1.client-channel.google.com 487 bytes in 116.0000 us [ 4.1983 MBps ]
4. Rationalization in logs.
5. Optimization done in HTTPS. Initial SSL connect will be faster now.
6. Optimization in memory utilization.
7. Optimization in SafeSquid init script and TCP tuning script.

 

BugFixes

1. Fix for Captive Portal feature.
   It was observed a conflict and broken web-security client implementation via Captive Portal.
   Identified the flaw and fixed it.
2. Fix for TCP tuning script.
   It was observed that tcp_tune.sh script was passing wrong variables to init script which then resulted in SafeSquid crashing immediately at start.
   Identified the flaw and fixed it.
