This was introduced on accident in r165243, when return sites were unified
to add a lock around LibAliasProxyRule().

inet_ntoa() cannot be used safely in a multithreaded environment
because it uses a static local buffer. Instead, use inet_ntoa_r()
with a buffer on the caller's stack.

- Remove locking, since all module(9) events are running under &Giant.
- Use TAILQ for protocol handlers and fix a bug which led to
infinite cycle. Bug found in VirtualBox [1]
- Simplify code everywhere.
- Fix documentation.

and that can drive someone crazy. While m_get2() is young and not
documented yet, change its order of arguments to match m_getm2().
Sorry for churn, but better now than later.
The SYSCTL_NODE macro defines a list that stores all child-elements of
that node. If there's no SYSCTL_DECL macro anywhere else, there's no
reason why it shouldn't be static.
- While here, remove a paragraph about userspace operation that
has been outdated for some time. [2]

alias address needs to be specified.
Add inbound handler to the alias_ftp module. It helps handle active
FTP transfer mode for the case with external clients and FTP server behind
NAT. Fix passive FTP transfer case for server behind NAT using redirect with
external IP address different from NAT ip address.

"globalport" option for multiple NAT instances.
If ipfw rule contains "global" keyword instead of nat_number, then
for each outgoing packet ipfw_nat looks up translation state in all
configured nat instances. If an entry is found, packet aliased
according to that entry, otherwise packet is passed unchanged.
User can specify "skip_global" option in NAT configuration to exclude
an instance from the lookup in global mode.

error), toss the packet.
longer do we require SCTP to be in the kernel for the
lib to be able to handle SCTP. We do this by moving
the CRC32c checksum into libkern/crc32.c and then adjusting
all routines to use the common methods. Note that this
will improve the performance of iSCSI since they were
using the old single 256 bit table lookup versus the
slicing 8 algorithm (which gives a 4x speed up in
CRC32c calculation :-D)
