from the incoming SYN handling section of tcp_input().
Enforcement of the accept queue limits is done by sonewconn() after the
3WHS is completed. It is not necessary to have an earlier check before a
connection request enters the SYN cache awaiting the full handshake. It
rather limits the effectiveness of the syncache by preventing legit and
illegit connections from entering it and having them shaken out before we
hit the real limit which may have vanished by then.
Change return value of syncache_add() to void. No status communication
is required.
when the ACK is invalid and doesn't belong to any registered connection,
either in syncache or through SYN cookies. True but a NULL struct socket
is returned when the 3WHS completed but the socket could not be created
due to insufficient resources or limits reached.
For both cases an RST is sent back in tcp_input().
A logic error leading to a panic is fixed where syncache_expand() would
free the mbuf on socket allocation failure but tcp_input() later supplies
it to tcp_dropwithreset() to issue a RST to the peer.

get exact overhead from user-level, but I have not done it to keep

* Break out the boot0 loader selection into a variable - NANO_BOOTLOADER -
so people like me with VGA consoles can override the default (which is
to use boot0sio)
* Put the boot0 configuration options in NANO_BOOT0CFG in case you want
to override the defaults.
* Modify nanobsd.8 to reflect the changes and hint the console default is
serial.

This fixes infinite restart in the following case:

Unlike GNU make, BSD make considers "Makefile" node as remade even
if "foo" is up-to-date and was not actually rebuilt.
GNU make does not consider nodes without commands as remade if child nodes
were not actually rebuilt.
Most probably, more proper fix would be to bring BSD make behaviour in-line
with GNU make but this would be more intrusive change.

Work around this problem by replacing the tv_sec == 0 check with a
<= 3600 check. It's doubtful anyone will be booting within an hour of the
Epoch, let alone care about a few seconds worth of nonzero timestamps. It's
a hackish work around, but it does work and I have not experienced any
negatives in my testing.

and new SCBs were allocated on demand later if needed. This has two
problems. First, allocating SCBs involves allocating contiguous memory,
and if memory is exhausted then the VM will try to page out to satisfy
the request, leading to recursion and deadlock. The second problem is
that it can cause lock order reversals due to parts of the VM still being
under Giant.
Fix the problem be allocating the full pool at driver attach, when it is
safe to do so.
1. CMSG_NXTHDR(mhdr, cmsg) is supposed to dereference cmsg and return
the next header in the chain. If cmsg is NULL it should return
the first header, behaving essentially like CMSG_FIRSTHDR().
2. inet6_rth_(space|init|add) should do basic checking on their input
to verify that the number of headers (segments) is
between 0 and 127 inclusive.

1. The static buffer that ping6(8) uses to hold the control data
it gets from recvmsg(2) is too small in some cases.
2. When it prints the extra header information it doesn't do
any checking to make sure the data it's printing is within
the bounds of the supplied buffer.
Fix this by:
o Increasing the buffer to hold extra headers to 10240 bytes (the minimum
according to RFC3542 sec. 20.1) and allocate it dynamically.
o In verbose mode, specify a warning if any control data from recvmsg(2)
was truncated because the buffer was too small.
o When printing the extra headers make sure not to overrun the buffer
boundaries.
