The problem is that the statfs(2) system call used to determine the relevant
mount point returns path within real root in the f_mntonname, causing
nmount(2) system call to fail with ENOENT.
Use a bit of heuristics to skip over few starting path elements when it
happens until we hit an actual mount point.
For this to work properly the whole mount should be accessible within the
chroot, it's going to still fail if chroot only has access to a part of the
mounted fs.

The module is designed for modification of a packets of any protocols.
For now it implements only TCP MSS modification. It adds the external
action handler for "tcp-setmss" action.
A rule with tcp-setmss action does additional check for protocol and
TCP flags. If SYN flag is present, it parses TCP options and modifies
MSS option if its value is greater than configured value in the rule.
Then it adjustes TCP checksum if needed. After handling the search
continues with the next rule.

This opcode can be used to attach some data to external action opcode.
And unlike to O_EXTERNAL_INSTANCE opcode, this opcode does not require
creating of named instance to pass configuration arguments to external
action handler. The data is coming just next to O_EXTERNAL_ACTION opcode.
The userlevel part currenly supports formatting for opcode with ipfw_insn
size, by default it expects u16 numeric value in the arg1.

Also make sure that the renewal is never more than 1/2 * expiry and
rebind never more than 7/4 * renewal (the default values in the spec).
This should allow adjusting high values from the server as well as
making sure the values from the server make sense.
Renewal and rebind times will be adjusted down if the expiry time is set
very high in a server, not the other way around. This change just makes
sure the values keep making sense.

With the following in /etc/fstab:

swap will not be enabled, with `swapon -aL' complaining:
swapon: Invalid option: late
This happens because swap_on_geli_args() which parses geli arguments
out of all mount options does not expect late or noauto among them.
Fix this by explicitly allowing these arguments.

Currently are defined three scopes: global, ifnet, and pcb.
Generic security policies that IKE daemon can add via PF_KEY interface
or an administrator creates with setkey(8) utility have GLOBAL scope.
Such policies can be applied by the kernel to outgoing packets and checked
agains inbound packets after IPsec processing.
Security policies created by if_ipsec(4) interfaces have IFNET scope.
Such policies are applied to packets that are passed through if_ipsec(4)
interface.
And security policies created by application using setsockopt()
IP_IPSEC_POLICY option have PCB scope. Such policies are applied to
packets related to specific socket. Currently there is no way to list
PCB policies via setkey(8) utility.
Modify setkey(8) and libipsec(3) to be able distinguish the scope of
security policies in the `setkey -DP` listing. Add two optional flags:
'-t' to list only policies related to virtual *tunneling* interfaces,
i.e. policies with IFNET scope, and '-g' to list only policies with GLOBAL
scope. By default policies from all scopes are listed.
To implement this PF_KEY's sadb_x_policy structure was modified.
sadb_x_policy_reserved field is used to pass the policy scope from the
kernel to userland. SADB_SPDDUMP message extended to support filtering
by scope: sadb_msg_satype field is used to specify bit mask of requested
scopes.
For IFNET policies the sadb_x_policy_priority field of struct sadb_x_policy
is used to pass if_ipsec's interface if_index to the userland. For GLOBAL
policies sadb_x_policy_priority is used only to manage order of security
policies in the SPDB. For IFNET policies it is not used, so it can be used
to keep if_index.
After this change the output of `setkey -DP` now looks like:
# setkey -DPt
0.0.0.0/0[any] 0.0.0.0/0[any] any
