TTL a packet must have when received on a socket. All packets with a
lower TTL are silently dropped. Works on already connected/connecting
and listening sockets for RAW/UDP/TCP.
This option is only really useful when set to 255 preventing packets
from outside the directly connected networks reaching local listeners
on sockets.
Allows userland implementation of 'The Generalized TTL Security Mechanism
(GTSM)' according to RFC3682. Examples of such use include the Cisco IOS
BGP implementation command "neighbor ttl-security".

Fixes the TCP issues raised in I-D draft-gont-icmp-payload-00.txt.
This aids in-the-wild debugging a lot and allows the receiver to do
more elaborate checks on the validity of the response.

The use of ~PDRMASK is problematic if the PDE has PG_NX set. Specifically,
the PG_NX bit will be included in the physical address if ~PDRMASK is used.

when if_ral.ko is loaded. This makes it possible to load if_ral w/o

to show in traceroutes the actual path a packet has taken instead of
the possibly different return path.

is a workaround for non-symetric teardown of the file systems at
shutdown with respect to the mount order at boot. The proper long term
fix is to properly detach devfs from the root mount before unmounting
each, and should be implemented, but since the problem is non-harmful,
this temporary band-aid will prevent false positive bug reports and
unnecessary error output for 6.0-RELEASE.

sizeof(struct g_eli_metadata) will return the exact number of bytes needed
for storing it on the disk.
Without this change GELI was unusable on amd64 (and probably other 64-bit
archs), because sizeof(struct g_eli_metadata) was greater than 512 bytes
and geli(8) was failing on assertion.
