df53ae0fdd Remove portsnap(8)
Rather than having a tool in the FreeBSD base system for obtaining

and then `git clone https://git.FreeBSD.org/ports.git /usr/ports`.

The portsnap servers will continue operating until FreeBSD 13 reaches
its End-of-Life, and portsnap is available from the ports tree as
ports-mgmt/portsnap.

d862b165a6 bridge: Add support for emulated netmap mode
if_bridge receives packets via a special interface, if_bridge_input,
rather than by if_input.  Thus, netmap's usual hooking of ifnet routines
does not work as expected.  Instead, modify bridge_input() to pass
packets directly to netmap when it is enabled.  This applies to both
locally delivered packets and forwarded packets.

When a netmap application transmits a packet by writing it to the host
TX ring, the mbuf chain is passed to if_input, which ordinarily points
to ether_input().  However, when transmitting via if_bridge,
bridge_input() needs to see the packet again in order to decide whether
to deliver or forward.  Thus, introduce a new protocol flag,
M_BRIDGE_INJECT, which 1) causes the packet to be passed to
bridge_input() again after Ethernet processing, and 2) avoids passing
the packet back to netmap.  The source MAC address of the packet is used
to determine the original "receiving" interface.

cab1056105 kdb: Modify securelevel policy
Currently, sysctls which enable KDB in some way are flagged with
CTLFLAG_SECURE, meaning that you can't modify them if securelevel > 0.
This is so that KDB cannot be used to lower a running system's
securelevel, see commit 3d7618d8bf.  However, the newer mac_ddb(4)
restricts DDB operations which could be abused to lower securelevel
while retaining some ability to gather useful debugging information.

To enable the use of KDB (specifically, DDB) on systems with a raised
securelevel, change the KDB sysctl policy: rather than relying on
CTLFLAG_SECURE, add a check of the current securelevel to kdb_trap().
If the securelevel is raised, only pass control to the backend if MAC
specifically grants access; otherwise simply check to see if mac_ddb
vetoes the request, as before.

Add a new secure sysctl, debug.kdb.enter_securelevel, to override this
behaviour.  That is, the sysctl lets one enter a KDB backend even with a
raised securelevel, so long as it is set before the securelevel is
raised.
