Vladimir Sementsov-Ogievskiy 1d17922a28 nbd/server: structurize option reply sending

Eric Blake 894e02804c nbd/server: Add helper functions for parsing option payload
Rather than making every callsite perform length sanity checks
and error reporting, add the helper functions nbd_opt_read()
and nbd_opt_drop() that use the length stored in the client
struct; also add an assertion that optlen is 0 before any
option (ie. any previous option was fully handled), complementing
the assertion added in an earlier patch that optlen is 0 after
all negotiation completes.

Note that the call in nbd_negotiate_handle_export_name() does
not use the new helper (in part because the server cannot
reply to NBD_OPT_EXPORT_NAME - it either succeeds or the
connection drops).

Based on patches by Vladimir Sementsov-Ogievskiy.

Eric Blake 32f158a635 nbd/server: Better error for NBD_OPT_EXPORT_NAME failure
When a client abruptly disconnects before we've finished reading
the name sent with NBD_OPT_EXPORT_NAME, we are better off logging
the failure as EIO (we can't communicate with the client), rather
than EINVAL (the client sent bogus data).

Vladimir Sementsov-Ogievskiy 0cfae925d2 nbd/server: refactor negotiation functions parameters
Instead of passing currently negotiating option and its length to
many of negotiation functions let's just store them on NBDClient
struct to be state-variables of negotiation phase.

This unifies semantics of negotiation functions and allows
tracking changes of remaining option length in future patches.

Asssert that optlen is back to 0 after negotiation (including
old-style connections which don't negotiate), although we need
more patches before we can assert optlen is 0 between options
during negotiation.

Dr. David Alan Gilbert aa777e297c cpu_physical_memory_sync_dirty_bitmap: Another alignment fix
This code has an optimised, word aligned version, and a boring
unaligned version. My commit f70d345 fixed one alignment issue, but
there's another.

The optimised version operates on 'longs' dealing with (typically) 64
pages at a time, replacing the whole long by a 0 and counting the bits.
If the Ramblock is less than 64bits in length that long can contain bits
representing two different RAMBlocks, but the code will update the
bmap belinging to the 1st RAMBlock only while having updated the total
dirty page count for both.

This probably didn't matter prior to 6b6712ef which split the dirty
bitmap by RAMBlock, but now they're separate RAMBlocks we end up
with a count that doesn't match the state in the bitmaps.

Symptom:
  Migration showing a few dirty pages left to be sent constantly
  Seen on aarch64 and x86 with x86+ovmf

Eric Blake f4bdc13e49 checkpatch: Enforce proper do/while (0) style
Use of a loop construct for code that is not intended to repeat
does not make much idiomatic sense, except in one place: it is a
common usage in macros in order to wrap arbitrary code with
single-statement semantics.  But when used in a macro, it is more
typical for the caller to supply the trailing ';' when calling
the macro.

Although qemu coding style frowns on bare:
  if (cond)
    statement1;
  else
    statement2;
where extra semicolons actually cause syntax errors, we still
want our macro styles to be easily copied to other projects.
Thus, declare it an error if we encounter any form of 'while (0)'
with a semicolon in the same line.

Eric Blake 2562755ee7 maint: Fix macros with broken 'do/while(0); ' usage
The point of writing a macro embedded in a 'do { ... } while (0)'
loop (particularly if the macro has multiple statements or would
otherwise end with an 'if' statement) is so that the macro can be
used as a drop-in statement with the caller supplying the
trailing ';'.  Although our coding style frowns on brace-less 'if':
  if (cond)
    statement;
  else
    something else;
that is the classic case where failure to use do/while(0) wrapping
would cause the 'else' to pair with any embedded 'if' in the macro
rather than the intended outer 'if'.  But conversely, if the macro
includes an embedded ';', then the same brace-less coding style
would now have two statements, making the 'else' a syntax error
rather than pairing with the outer 'if'.  Thus, even though our
coding style with required braces is not impacted, ending a macro
with ';' makes our code harder to port to projects that use
brace-less styles.

The change should have no semantic impact.  I was not able to
fully compile-test all of the changes (as some of them are
examples of the ugly bit-rotting debug print statements that are
completely elided by default, and I didn't want to recompile
with the necessary -D witnesses - cleaning those up is left as a
bite-sized task for another day); I did, however, audit that for
all files touched, all callers of the changed macros DID supply
a trailing ';' at the callsite, and did not appear to be used
as part of a brace-less conditional.

Found mechanically via: $ git grep -B1 'while (0);' | grep -A1 \\\\

Eric Blake 241187c118 tests: Avoid 'do/while(false); ' in vhost-user-bridge
Use of a do/while(0) loop as a way to allow break statements in
the middle of execute-once code is unusual.  More typical is
the use of goto for early exits, with a label at the end of
the execute-once code, rather than nesting code in a scope;
however, the comment at the end of the existing code makes this
alternative a bit unpractical.

So, to avoid false positives from a future syntax check about
'while (false);', and to keep the loop form (in case someone
ever does add DONTWAIT support, where they can just as easily
manipulate the initial loop condition or add an if around the
final 'break'), I opted to use the form of a while(1) loop (the
break as an early exit is more idiomatic there), coupled with
a final break preserving the original comment.

Eric Blake 19a4d43ef0 chardev: Use goto/label instead of do/break/while(0)
Use of a do/while(0) control flow in order to permit an early break
is an unusual paradigm, and triggers a false positive with a planned
future syntax check against 'while (0);'.  Rewrite the code to use a
goto instead.  This patch temporarily keeps an extra level of
indentation to highlight the change; the next patch cleans it up.

Eric Blake 1b4c0a0436 net: Drop unusual use of do { } while (0);
For a couple of macros in pcnet.c, we have to provide a new scope
to avoid compiler warnings about declarations in the middle of a
switch statement that aren't in a sub-scope.  But use of
'do { ... } while (0);' merely to provide that new scope is arcane
overkill, compared to just using '{ ... }'.

Paolo Bonzini db08b687cd cpus: unify qemu_*_wait_io_event
Except for round-robin TCG, every other accelerator is using more or
less the same code around qemu_wait_io_event_common.  The exception
is HAX, which also has to eat the dummy APC that is queued by
qemu_cpu_kick_thread.

We can add the SleepEx call to qemu_wait_io_event under "if
(!tcg_enabled())", since that is the condition that is used in
qemu_cpu_kick_thread, and unify the function for KVM, HAX, HVF and
multi-threaded TCG.  Single-threaded TCG code can also be simplified
since it is only used in the round-robin, sleep-if-all-CPUs-idle case.

scsi_write_same_complete() can retry the write if the request was
unaligned.  Make sure to release the AioContext when that code path is
taken!

This patch fixes a hang when QEMU terminates after an unaligned WRITE
SAME request has been processed with dataplane.  The hang occurs because
iothread_stop_all() cannot acquire the AioContext lock that was leaked
by the IOThread in scsi_write_same_complete().

It looks like the rest of the code copes with ndata being larger than
sizeof(sector), so limit the memcpy() range.
