Currently, vhost-user does not implement any means for notifying the
backend about guest endianess. This commit introduces a new message
called VHOST_USER_SET_VRING_ENDIAN which is analogous to the ioctl()
called VHOST_SET_VRING_ENDIAN used for kernel vhost backends. Such
message is necessary for backends supporting legacy (pre-1.0) virtio
devices running in big-endian guests.

Code that checks dstate is unaware of SystemTap and LTTng UST dstate, so
the following trace event will not fire when solely enabled by SystemTap
or LTTng UST:
if (trace_event_get_state(TRACE_MY_EVENT)) {
str = g_strdup_printf("Expensive string to generate ...",
...);
trace_my_event(str);
g_free(str);
}
Add trace_event_get_state_backends() to fetch backend dstate. Those
backends that use QEMU dstate fetch it as part of
generate_h_backend_dstate().
Update existing trace_event_get_state() callers to use
trace_event_get_state_backends() instead.

This patch documents (including their QMP invocations) all the four
major kinds of live block operations:
- `block-stream`
- `block-commit`
- `drive-mirror` (& `blockdev-mirror`)
- `drive-backup` (& `blockdev-backup`)
Things considered while writing this document:
- Use reStructuredText as markup language (with the goal of generating
the HTML output using the Sphinx Documentation Generator). It is
gentler on the eye, and can be trivially converted to different
formats. (Another reason: upstream QEMU is considering to switch to
Sphinx, which uses reStructuredText as its markup language.)
- Raw QMP JSON output vs. 'qmp-shell'. I debated with myself whether
to only show raw QMP JSON output (as that is the canonical
representation), or use 'qmp-shell', which takes key-value pairs. I
settled on the approach of: for the first occurrence of a command,
use raw JSON; for subsequent occurrences, use 'qmp-shell', with an
occasional exception.
- Usage of `-blockdev` command-line.
- Usage of 'node-name' vs. file path to refer to disks. While we have
`blockdev-{mirror, backup}` as 'node-name'-alternatives for
`drive-{mirror, backup}`, the `block-commit` command still operates
on file names for parameters 'base' and 'top'. So I added a caveat
at the beginning to that effect.
Refer this related thread that I started (where I learnt
`block-stream` was recently reworked to accept 'node-name' for 'top'
and 'base' parameters):
https://lists.nongnu.org/archive/html/qemu-devel/2017-05/msg06466.html
"[RFC] Making 'block-stream', and 'block-commit' accept node-name"
All commands showed in this document were tested while documenting.
Thanks: Eric Blake for the section: "A note on points-in-time vs file
names". This useful bit was originally articulated by Eric in his
KVMForum 2015 presentation, so I included that specific bit in this
document.

We traditionally mark optional members #optional in the doc comment.
Before commit 3313b61, this was entirely manual.
Commit 3313b61 added some automation because its qapi2texi.py relied
on #optional to determine whether a member is optional. This is no
longer the case since the previous commit: the only thing qapi2texi.py
still does with #optional is stripping it out. We still reject bogus
qapi-schema.json and six places for qga/qapi-schema.json.
Thus, you can't actually rely on #optional to see whether something is
optional. Yet we still make people add it manually. That's just
busy-work.
Drop the code to check, fix up and strip out #optional, along with all
instances of #optional. To keep it out, add code to reject it, to be
dropped again once the dust settles.
No change to generated documentation.

Since we added the documentation generator in commit 3313b61, doc
comments are mandatory. That's a very good idea for a schema that
needs to be documented, but has proven to be annoying for testing.
Make doc comments optional again, but add a new directive
{ 'pragma': { 'doc-required': true } }
to let a QAPI schema require them.
Add test cases for the new pragma directive. While there, plug a
minor hole in includ directive test coverage.
Require documentation in the schemas we actually want documented:
qapi-schema.json and qga/qapi-schema.json.

documentation, but for now, simply make it refuse to run unless the

More precisely, the "x-file-slots" count is bumped for all machine types
that:
(a) use fw_cfg, and
(b) are not versioned (hence migration is not expected to work for them
across QEMU releases anyway), or have version 2.9.
This affects machine types implemented in the following source files:
- "hw/arm/virt.c". The "virt-*" machine type is versioned, and the <= 2.8
versions already depend on HW_COMPAT_2_8 (see commit e353aac51b).
Therefore adding the "x-file-slots" compat values to HW_COMPAT_2_8
suffices.
- "hw/i386/pc.c". The "pc-i440fx-*" (including "pc-*") and "pc-q35-*"
machine types are versioned. Modifying HW_COMPAT_2_8 is sufficient here
too (see commit "pc: Add 2.9 machine-types"). The "isapc" machtype is
not versioned. The "xenfv" machine type, which uses fw_cfg for direct
kernel booting, is also not versioned.
- "hw/ppc/mac_newworld.c". The "mac99" machine type is not versioned.
- "hw/ppc/mac_oldworld.c". The "g3beige" machine type is not versioned.
- "hw/sparc/sun4m.c". None of the 9 machine types defined in this file
appear versioned.
- "hw/sparc64/sun4u.c". None of the 3 machine types defined in this file
appear versioned.

We'd like to raise the value of FW_CFG_FILE_SLOTS. Doing it naively could
lead to problems with backward migration: a more recent QEMU (running an
older machine type) would allow the guest, in fw_cfg_select(), to select a
high key value that is unavailable in the same machine type implemented by
the older (target) QEMU. On the target host, fw_cfg_data_read() for
example could dereference nonexistent entries.
As first step, size the FWCfgState.entries[*] and FWCfgState.entry_order
arrays dynamically. All three array sizes will be influenced by the new
field FWCfgState.file_slots (and matching device property).
Make the following changes:
- Replace the FW_CFG_FILE_SLOTS macro with FW_CFG_FILE_SLOTS_MIN (minimum
count of fw_cfg file slots) in the header file. The value remains 0x10.
- Replace all uses of FW_CFG_FILE_SLOTS with a helper function called
fw_cfg_file_slots(), returning the new property.
- Eliminate the macro FW_CFG_MAX_ENTRY, and replace all its uses with a
helper function called fw_cfg_max_entry().
- In the MMIO- and IO-mapped realize functions both, allocate all three
arrays dynamically, based on the new property.
- The new property defaults to FW_CFG_FILE_SLOTS_MIN. This is going to be
customized in the following patches.

A QemuLockCnt comprises a counter and a mutex, with primitives
to increment and decrement the counter, and to take and release the
mutex. It can be used to do lock-free visits to a data structure
whenever mutexes would be too heavy-weight and the critical section
is too long for RCU.
This could be implemented simply by protecting the counter with the
mutex, but QemuLockCnt is harder to misuse and more efficient.

As the name suggests, the qapi2texi script converts JSON QAPI
description into a texi file suitable for different target
formats (info/man/txt/pdf/html...).
It parses the following kind of blocks:
Free-form:
##
# = Section
# == Subsection
#
# Some text foo with *emphasis*
# 1. with a list
# 2. like that
#
# And some code:
# | $ echo foo
# | -> do this
# | <- get that
#
##
Symbol description:
##
# @symbol:
#
# Symbol body ditto ergo sum. Foo bar
# baz ding.
#
# @param1: the frob to frobnicate
# @param2: #optional how hard to frobnicate
#
# Returns: the frobnicated frob.
# If frob isn't frobnicatable, GenericError.
#
# Since: version
# Notes: notes, comments can have
# - itemized list
# - like this
#
# Example:
#
# -> { "execute": "quit" }
# <- { "return": {} }
#
##
That's roughly following the following EBNF grammar:
api_comment = "##\n" comment "##\n"
comment = freeform_comment | symbol_comment
freeform_comment = { "# " text "\n" | "#\n" }
symbol_comment = "# @" name ":\n" { member | tag_section | freeform_comment }
member = "# @" name ':' [ text ] "\n" freeform_comment
tag_section = "# " ( "Returns:", "Since:", "Note:", "Notes:", "Example:", "Examples:" ) [ text ] "\n" freeform_comment
text = free text with markup
Note that the grammar is ambiguous: a line "# @foo:\n" can be parsed
both as freeform_comment and as symbol_comment. The actual parser
recognizes symbol_comment.
See docs/qapi-code-gen.txt for more details.
Deficiencies and limitations:
- the generated QMP documentation includes internal types
- union type support is lacking
- type information is lacking in generated documentation
- doc comment error message positions are imprecise, they point
to the beginning of the comment.
- a few minor issues, all marked TODO/FIXME in the code

This patch adds support of recording and replaying network packets in
irount rr mode.
Record and replay for network interactions is performed with the network filter.
Each backend must have its own instance of the replay filter as follows:
-netdev user,id=net1 -device rtl8139,netdev=net1
-object filter-replay,id=replay,netdev=net1
Replay network filter is used to record and replay network packets. While
recording the virtual machine this filter puts all packets coming from
the outer world into the log. In replay mode packets from the log are
injected into the network device. All interactions with network backend
in replay mode are disabled.

Because TFTP does not support byte ranges, it was never usable with our
curl block driver. Since apparently nobody has ever complained loudly
enough for someone to take care of the issue until now, it seems
reasonable to assume that nobody has ever actually used it.
Therefore, it should be safe to just drop it from curl's protocol list.
[Jeff Cody: Below is additional summary pulled, with some rewording,
from followup emails between Max and Markus, to explain what
worked and what didn't]
TFTP would sometimes work, to a limited extent, for images <= the curl
"readahead" size, so long as reads started at offset zero. By default,
that readahead size is 256KB.
Reads starting at a non-zero offset would also have returned data from a
zero offset. It can become more complicated still, with mixed reads at
zero offset and non-zero offsets, due to data buffering.
In short, TFTP could only have worked before in very specific scenarios
with unrealistic expectations and constraints.
