Since commit 2ca34b5087 ("staging: axis-fifo: Correct handling of
tx_fifo_depth for size validation"), write() operations with packets
larger than 'tx_fifo_depth - 4' words are no longer rejected with -EINVAL.
Fortunately, the packets are not actually getting transmitted to hardware,
otherwise they would be raising a 'Transmit Packet Overrun Error'
interrupt, which requires a reset of the TX circuit to recover from.
Instead, the request times out inside wait_event_interruptible_timeout()
and always returns -EAGAIN, since the wake up condition can never be true
for these packets. But still, they unnecessarily block other tasks from
writing to the FIFO and the EAGAIN return code signals userspace to retry
the write() call, even though it will always fail and time out.
According to the AXI4-Stream FIFO reference manual (PG080), the maximum
valid packet length is 'tx_fifo_depth - 4' words, so attempting to send
larger packets is invalid and should not be happening in the first place:
> The maximum packet that can be transmitted is limited by the size of
> the FIFO, which is (C_TX_FIFO_DEPTH–4)*(data interface width/8) bytes.
Therefore, bring back the old behavior and outright reject packets larger
than 'tx_fifo_depth - 4' with -EINVAL. Add a comment to explain why the
check is necessary. The dev_err() message was removed to avoid cluttering
the dmesg log if an invalid packet is received from userspace.

As long as "sym" doesn't contain any odd characters, no quoting is
required for its use with .quad / .long. In fact the quotation gets in
the way with gas 2.25; it's only from 2.26 onwards that quoted symbols
are half-way properly supported.
However, assembly being different from C anyway, drop
__ADDRESSABLE_ASM_STR() and its helper macro altogether. A simple
.global directive will suffice to get the symbol "declared", i.e. into
the symbol table. While there also stop open-coding STATIC_CALL_TRAMP()

Now that FRED provides C-code entry points for handling IRQs, use the
FRED infrastructure for forwarding IRQs even if FRED is fully
disabled, e.g. isn't supported in hardware. Avoiding the non-FRED
assembly trampolines into the IDT handlers for IRQs eliminates the
associated non-CFI indirect call (KVM performs a CALL by doing a
lookup on the IDT using the IRQ vector).
Keep NMIs on the legacy IDT path, as the FRED NMI entry code relies on
FRED's architectural behavior with respect to NMI blocking, i.e. doesn't
jump through the myriad hoops needed to deal with IRET "unexpectedly"
unmasking NMIs. KVM's NMI path already makes a direct CALL to C-code,
i.e. isn't problematic for CFI. KVM does make a short detour through
assembly code to build the stack frame, but the "FRED entry from KVM"
path does the same.
Force FRED for 64-bit kernels if KVM_INTEL is enabled, as the benefits of
eliminating the IRQ trampoline usage far outwieghts the code overhead for
FRED.

Modify asm_fred_entry_from_kvm() to allow it to be invoked by KVM even
when FRED isn't fully enabled, e.g. when running with
CONFIG_X86_FRED=y on non-FRED hardware. This will allow forcing KVM
to always use the FRED entry points for 64-bit kernels, which in turn
will eliminate a rather gross non-CFI indirect call that KVM uses to
trampoline IRQs by doing IDT lookups.
The point of asm_fred_entry_from_kvm() is to bridge between C
(vmx:handle_external_interrupt_irqoff()) and more C
(__fred_entry_from_kvm()) while changing the calling context to appear
like an interrupt (pt_regs). Making the whole thing bound by C ABI.
All that remains for non-FRED hardware is to restore RSP (to undo the
redzone and alignment). However the trivial change would result in
code like:
push %rbp
mov %rsp, %rbp
sub $REDZONE, %rsp
and $MASK, %rsp
PUSH_AND_CLEAR_REGS
push %rbp
POP_REGS
pop %rbp <-- *objtool fail*
mov %rbp, %rsp
pop %rbp
ret
And this will confuse objtool something wicked -- it gets confused by
the extra pop %rbp, not realizing the push and pop preserve the value.
Rather than trying to each objtool about this, recognise that since
the code is bound by C ABI on both ends and interrupts are not allowed
to change pt_regs (only exceptions are) it is sufficient to PUSH_REGS
in order to create pt_regs, but there is no reason to POP_REGS --
provided the callee-saved registers are preserved.
So avoid clearing callee-saved regs and skip POP_REGS.

What used to be a simple few instructions has turned into a giant mess
(for x86_64). Not only does it use static_branch wrong, it mixes it
with dynamic branches for no apparent reason.
Notably it uses static_branch through an out-of-line function call,
which completely defeats the purpose, since instead of a simple
JMP/NOP site, you get a CALL+RET+TEST+Jcc sequence in return, which is
absolutely idiotic.
Add to that a dynamic test of hyperv_paravisor_present, something

Replace fastops with C based stubs. There are a bunch of problems with
the current fastop infrastructure, most all related to their special
calling convention, which bypasses the normal C-ABI.
There are two immediate problems with this at present:
- it relies on RET preserving EFLAGS; whereas C-ABI does not.
- it circumvents compiler based control-flow-integrity checking
because its all asm magic.
The first is a problem for some mitigations where the
x86_indirect_return_thunk needs to include non-trivial work that
clobbers EFLAGS (eg. the Skylake call depth tracking thing).
The second is a problem because it presents a 'naked' indirect call on
kCFI builds, making it a prime target for control flow hijacking.
Additionally, given that a large chunk of virtual machine performance
relies on absolutely avoiding vmexit these days, this emulation stuff
just isn't that critical for performance anymore.
As such, replace the fastop calls with normal C functions using the
'execute' member.
As noted by Paolo: this code was performance critical for pre-Westmere
(2010) and only when running big real mode code.
