ae7c0700dc sh: Fix break/continue/return sometimes not skipping the rest of dot script.
In our implementation and most others, a break or continue in a dot script
can break or continue a loop outside the dot script. This should cause all
further commands in the dot script to be skipped. However, cmdloop() did not
know about this and continued to parse and execute commands from the dot
script.

As described in the man page, a return in a dot script in a function returns
from the function, not only from the dot script. There was a similar issue
as with break and continue. In various other shells, the return appears to
return from the dot script, but POSIX seems not very clear about this.

b6fbd4d50d no-op commit to note that the example given in the previous commit is
a very bad one, since the shift does not actually overflow.  This is
a better example (assuming uint64_t = unsigned long long):

  ~0LLU >> 9             =   0x7fffffffffffffLLU
  ~0LLU >> 9 << 10       = 0xfffffffffffffc00LLU
  ~0LLU >> 9 << 10 >> 10 =   0x3fffffffffffffLLU

 ((uint64_t)1 << 53) << 10 = 0x8000000000000000

e4e9266071 Fix the interaction between 'ICMP fragmentation needed' MTU updates,
path MTU discovery and the tcp_minmss limiter for very small MTU's.

When the MTU suggested by the gateway via ICMP, or if there isn't
any the next smaller step from ip_next_mtu(), is lower than the
floor enforced by net.inet.tcp.minmss (default 216) the value is
ignored and the default MSS (512) is used instead.  However the
DF flag in the IP header is still set in tcp_output() preventing
fragmentation by the gateway.

Fix this by using tcp_minmss as the MSS and clear the DF flag if
the suggested MTU is too low.  This turns off path MTU dissovery
for the remainder of the session and allows fragmentation to be
done by the gateway.

Only MTU's smaller than 256 are affected.  The smallest official
MTU specified is for AX.25 packet radio at 256 octets.

2d8084397f Given the lag between introducing the options-compat and fixing the
bug in the config file was long, and merged to stable, we have to bump
the version here so that stable/8 kernels can have their required
version number bumped to make sure the right config is used.

e21944b6bd Turns out that it is a bad idea to have a missing compat option be a
fatal condition.  While it works out really well for diagnosing the
case where you want it, but don't have it, it works really badly for
the case where you don't have it and don't want it.  Remove the printf
and exit pair.  Replate it with simple return to silently ignore this
condition.

This is needed to fix the COMPAT_IA32 being required in options.* in
stable, but we need to run this change through -current first...

153e5b57af When using TSO and sending more than TCP_MAXWIN sendalot is set
and we loop back to 'again'.  If the remainder is less or equal
to one full segment, the TSO flag was not cleared even though
it isn't necessary anymore.  Enabling the TSO flag on a segment
that doesn't require any offloaded segmentation by the NIC may
cause confusion in the driver or hardware.

Reset the internal tso flag in tcp_output() on every iteration
of sendalot.

bee4e5afa9 Disable TCP inflight limiter by default.
It was experimental and interferes with the normal congestion control
algorithms by instating a separate, possibly lower, ceiling for the
amount of data that is in flight to the remote host.  With high speed
internet connections the inflight limit frequently has been estimated
too low due to the noisy nature of the RTT measurements.

This code gives way for the upcoming pluggable congestion control
framework.  It is the task of the congestion control algorithm to
set the congestion window and amount of inflight data without external
interference.

bbb2703b4f Simplify expand_number() by combining the (unrolled) loop with the
switch.  Since expand_number() does not accept negative numbers, switch

8c09aa57d9 In rip6_input(), in case of multicast, we might skip the normal processing
and go to the next iteration early if multicast filtering would decide that
this socket shall not receive the data.
Unlock the pcb in that case or we leak the read lock and next time trying
to get a write lock, would hang forever.

0405a5efe7 Reset switchtime to zero rather than the current CPU ticker (TSC) value.
It is more appropriate in this context because TSC MSR is reset to zero

to where it was before r211202.  It does not make a difference any more.
