Gleb Smirnoff cb8d7c44d6 tcp_syncache: add net.inet.tcp.syncache.see_other sysctl 
A security feature from c06f087ccb appeared to be a huge bottleneck
under SYN flood. To mitigate that add a sysctl that would make
syncache(4) globally visible, ignoring UID/GID, jail(2) and mac(4)
checks. When turned on, we won't need to call crhold() on the listening
socket credential for every incoming SYN packet.

FreeBSD Source:

This is the top level of the FreeBSD source directory.

FreeBSD is an operating system used to power modern servers, desktops, and embedded platforms. A large community has continually developed it for more than thirty years. Its advanced networking, security, and storage features have made FreeBSD the platform of choice for many of the busiest web sites and most pervasive embedded networking and storage devices.

For copyright information, please see the file COPYRIGHT in this directory. Additional copyright information also exists for some sources in this tree - please see the specific source directories for more information.

The Makefile in this directory supports a number of targets for building components (or all) of the FreeBSD source tree. See build(7), config(8), FreeBSD handbook on building userland, and Handbook for kernels for more information, including setting make(1) variables.
