- Tolerate applications that pass a NULL pointer for the buffer and
claim that the capacity of the buffer is nonzero.
- If an application passes in a non-NULL buffer pointer and claims the
buffer has zero capacity, we should free (well, realloc) it
anyway. It could have been obtained from malloc(0), so failing to
free it would be a small memory leak.

The reason for this is only to make sure that even in case we would
overflow the MAX_BRANDS sized array, the native FreeBSD brandinfo
would still be there and the system would be operational.

needed 2 new RX buffer functions with "get-char-from-buf" separated
from "advance-buf-pointer" so that the pointer could be advanced

virtual address 0, limiting the ability to convert a kernel
NULL pointer dereference into a privilege escalation attack.
If the sysctl is set to 0 a newly started process will not be able
to map anything in the address range of the first page (0 to PAGE_SIZE).
This is the default. Already running processes are not affected by this.
You can either change the sysctl or the tunable from loader in case
you need to map at a virtual address of 0, for example when running
any of the extinct species of a set of a.out binaries, vm86 emulation, ..
In that case set security.bsd.map_at_zero="1".

this address alias has a prefix matching that of another address
configured on the same interface, then the ARP entry for the alias
is not deleted from the ARP table when that address alias is removed.
This patch fixes the aforementioned issue.

Due to the amount of code removed by this, it seems that allowing unmatched
quotes was a deliberate imitation of System V sh and real ksh. Most other
shells do not allow unmatched quotes (e.g. bash, zsh, pdksh, NetBSD /bin/sh,
dash).

specific routes. When the routing table changes, for example,
when a new route with a more specific prefix is inserted into the
routing table, the flow-table is not updated to reflect that change.
As such existing connections cannot take advantage of the new path.
In some cases the path is broken. This patch will update the affected
flow-table entries when a more specific route is added. The route
entry is properly marked when a route is deleted from the table.
In this case, when the flow-table performs a search, the stale
entry is updated automatically. Therefore this patch is not
necessary for route deletion.

The EHCI HW can use the qtd_next field instead of qtd_altnext when a short
packet is received. This contradicts what is stated in the EHCI datasheet.
Also the total-bytes field in the status field of the following TD gets
corrupted upon reception of a short packet! We work this around in software by
not queueing more than one job/TD at a time of up to 16Kbytes! The bug has been
seen on multiple INTEL based EHCI chips. Other vendors have not been tested
yet.
- Applications using /dev/usb/X.Y.Z, where Z is non-zero are affected, but not
applications using LibUSB v0.1, v1.2 and v2.0.
- Mass Storage (umass) is affected.
