- config_ip_stealth : Do not send RST in response to a connect() to closed port - Willy Tarreau - 2006/01/09
Ported MadCamel's CONFIG_IP_STEALTH patch from 2.2.18. It permits to drop connection
attempts to closed ports without sending an RST back, which proves useful as a first
protection barrier. The ICMP code has been removed from the patch since kernel 2.4
provides everything to block outgoing ICMP.
- epoll-lt : a very scalable event polling mechanism - Davide Libenzi
The epoll mechanism is a powerful replacement for poll() and select() because
it is not sensible to the number of file-descriptors. It can transparently
support tens of thousands of FDs without any measurable slow down. It has been
merged into 2.6, but this patch allows demanding applications to achieve very
high performance on 2.4 too.
