Peter Maydell 910d7692e5 target/arm: Add v8M stack checks for LDRD/STRD (imm)
Add the v8M stack checks for:
 * LDRD (immediate)
 * STRD (immediate)

Loads and stores are more complicated than ADD/SUB/MOV, because we
must ensure that memory accesses below the stack limit are not
performed, so we can't simply do the check when we actually update
SP.

For these instructions, if the stack limit check triggers
we must not:
 * perform any memory access below the SP limit
 * update PC, SP or the load/store base register
but it is IMPDEF whether we:
 * perform any accesses above or equal to the SP limit
 * update destination registers for loads

For QEMU we choose to always check the limit before doing any other
part of the load or store, so we won't update any registers or
perform any memory accesses.

It is UNKNOWN whether the limit check triggers for a load or store
where the initial SP value is below the limit and one of the stores
would be below the limit, but the writeback moves SP to above the
limit.  For QEMU we choose to trigger the check in this situation.

Note that limit checks happen only for loads and stores which update
SP via writeback; they do not happen for loads and stores which
simply use SP as a base register.

Peter Maydell 597610eb39 target/arm: Add v8M stack limit checks on NS function calls
Check the v8M stack limits when pushing the frame for a
non-secure function call via BLXNS.

In order to be able to generate the exception we need to
promote raise_exception() from being local to op_helper.c
so we can call it from helper.c.

Peter Maydell c32da7aa62 target/arm: Add v8M stack checks on exception entry
Add checks for breaches of the v8M stack limit when the
stack pointer is decremented to push the exception frame
for exception entry.

Note that the exception-entry case is unique in that the
stack pointer is updated to be the limit value if the limit
is hit (per rule R_ZLZG).

Peter Maydell 846690dee8 virt: Suppress external aborts on virt-2.10 and earlier
In commit c79c0a314c we enabled emulation of external aborts
when the guest attempts to access a physical address with no
mapped device. In commit 4672cbd7be we suppress this for
most legacy boards to prevent breakage of previously working
guests, but we didn't suppress it in the 'virt' board, with
the rationale "we know that guests won't try to prod devices
that we don't describe in the device tree or ACPI tables". This
is mostly true, but we've had a report of a Linux guest image
that this did break. The problem seems to be that the guest
is (incorrectly) configured with a DEBUG_UART_PHYS value that
tells it there is a uart at 0x10009000 (which is true for
vexpress but not for virt), so in early bootup the kernel
probes this bogus address.

This is a misconfigured guest, so we don't need to worry
about it too much, but we can arrange that guests that ran
on QEMU v2.10 (before c79c0a314c) will still run on
the "virt-2.10" board model, by suppressing external aborts
only for that version and earlier. This seems a reasonable
compromise: "virt-2.10" is supposed to behave the same way
that "virt" did in the 2.10 release, and making it do that
provides a usable workaround for guests with bugs like this.

Gavin Grant 93a972f854 slirp: Propagate host TCP RST packet to the guest after socket disconnected
Commit 27d92ebc5e handled the case where the TCP
connection is abruptly closed via a RST packet, by checking for the ECONNRESET
errno. However it does not consider the case where the connection has been
half-closed by the host (FIN/ACK), then the host socket is disconnected. For
example, if the host application calls close() on the socket, then the
application exits.

In this case, the socket still exists due to the file descriptor in SLIRP, but
it is disconnected. recv() does not indicate an error since an orderly socket
close has previously occurred. The socket will then be stuck in FIN_WAIT_2,
until the peer sends FIN/ACK or a timeout occurs. Instead we can send a RST
to the peer and transition to the CLOSED state.

Andrew Oates 3d090aefe2 slirp: fix ICMP handling on macOS hosts
On Linux, SOCK_DGRAM+IPPROTO_ICMP sockets give only the ICMP packet when
read from.  On macOS, however, the socket acts like a SOCK_RAW socket
and includes the IP header as well.

This change strips the extra IP header from the received packet on macOS
before sending it to the guest.  SOCK_DGRAM ICMP sockets aren't
supported on other BSDs, but we enable this behavior for them as well to
treat the sockets the same as raw sockets.

The ISA has a 128/64-bit division instruction, though it assumes the
low 64-bits of the numerator are 0, and so requires a bit more fixup
than a full 128-bit division insn.

Richard Henderson 5dfbc9e490 softfloat: Fix division
The __udiv_qrnnd primitive that we nicked from gmp requires its
inputs to be normalized.  We were not doing that.  Because the
inputs are nearly normalized already, finishing that is trivial.

Replace div128to64 with a "proper" udiv_qrnnd, so that this
remains a reusable primitive.

Thomas Huth 0019d5c3a1 softfloat: Replace countLeadingZeros32/64 with clz32/64
Our minimum required compiler for compiling QEMU is GCC 4.1 these days,
so we can drop the support for compilers which do not provide the
__builtin_clz*() functions yet. Since the countLeadingZeros32/64 are
then identical to the clz32/64 functions, and we do not have to sync
the softloat 2 codebase with upstream anymore (softloat 3 is a complete
rewrite) we can simply replace the functions with our QEMU versions.

- scalbn for fixed point
- muladd variants
