[libnbd PATCH v3 00/22] NBD 64-bit extensions (libnbd portion)
by Eric Blake
v2 was here:
https://listman.redhat.com/archives/libguestfs/2022-November/030292.html
For v3, there are now approved specs to code to:
https://listman.redhat.com/archives/libguestfs/2023-April/031251.html
visible on an upstream branch at
https://github.com/NetworkBlockDevice/nbd/blob/extension-ext-header/doc/p...
(upstream leaves extensions in a branch state until there are multiple
implementations that comply with that extension)
as well as interoperability with counterpart qemu patches:
https://lists.gnu.org/archive/html/qemu-devel/2023-05/msg03607.html
also available at
https://repo.or.cz/qemu/ericb.git/shortlog/refs/tags/exthdr-v3
I'm still working on adding extended header support into nbdkit, which
will involve adding a v3 protocol for plugins; that work is probably
much further out.

022/22:[0004] [FC] 'api: Add nbd_[aio_]block_status_filter()'
The changes are mostly fallout from rebasing on top of style cleanups
that Laszlo has been working on, but also deal with some changes with
the spec compared to how it was proposed in v2 (for example, upstream
decided that for NBD_CMD_BLOCK_STATUS, the server should always use
64-bit replies, rather than making the client support both 32- and
64-bit replies).

[PATCH v3 00/14] qemu patches for 64-bit NBD extensions
by Eric Blake
v2 was here:
https://lists.gnu.org/archive/html/qemu-devel/2022-11/msg02340.html
Since then:
- upstream NBD has accepted the extension on a branch; once multiple
implementations interoperate based on that spec, it will be promoted
to mainline (my plan: qemu with this series, libnbd nearly ready to
go, nbdkit a bit further out)
- rebase to block changes in meantime
- drop RFC patches for 64-bit NBD_CMD_READ (NBD spec did not take them)
- per upstream spec decision, extended headers now mandates use of
NBD_REPLY_TYPE_BLOCK_STATUS_EXT rather than server choice based on
reply size, which in turn required rearranging server patches a bit
- other changes that I noticed while testing with parallel changes
being added to libnbd (link to those patches to follow in the next
week or so)
Eric Blake (14):
nbd/client: Use smarter assert
nbd/client: Add safety check on chunk payload length
nbd/server: Prepare for alternate-size headers
nbd: Prepare for 64-bit request effect lengths
nbd: Add types for extended headers
nbd/server: Refactor handling of request payload
nbd/server: Refactor to pass full request around
nbd/server: Support 64-bit block status
nbd/server: Initial support for extended headers
nbd/client: Initial support for extended headers
nbd/client: Accept 64-bit block status chunks
nbd/client: Request extended headers during negotiation
nbd/server: Prepare for per-request filtering of BLOCK_STATUS
nbd/server: Add FLAG_PAYLOAD support to CMD_BLOCK_STATUS

[libnbd PATCH] internal: Tweak use of attribute packed in union sbuf
by Eric Blake
While analyzing 'union sbuf' in preparation to add more members to the
union, I noticed several things related to __attribute__((packed))
that can be improved. It helps to note that that the bulk of the
members of 'union sbuf' are already marked packed structures from
nbd-protocol.h, where we don't need to repeat that annotation in
internal.h but where it does factor into sbuf alignment.
First, rather than open-coding the attribute name in internal.h (in
some places with inconsistent whitespace), we can reuse
NBD_ATTRIBUTE_PACKED already present from nbd-protocol.h.
Second, note that two of the union members are themselves substructs
with two parts: both sbuf.or and sbuf.sr need distinct storage for a
header (a packed structure) and a payload (a union of various items;
currently each member of both of those unions are already packed),
where the choice of union branch and overall size of the payload to be
read (if any) is determined by information in the header. Later
states then refer to information from both the header and payload, so
we need to keep the sub-structs (rather than hoisting the two parts of
the sub-struct into being directly-overlapping top-level members of
union sbuf proper). But because we don't know the payload size until
after the header is read, the state machine uses separate recv() calls
into the two parts of sbuf.or and sbuf.sr; and there is no specific
reason that the two reads need to occur into adjacent memory. Thus,
these two packed annotations buy us nothing at this layer and can be
safely elided.
Finally, there are benefits to naturally aligning uint64_t members,
whether or not hardware supports unaligned access. Even though we are
using attribute packed to match wire format (and some NBD messages do
not have any natural alignment), the judicious use of a non-packed
uint64_t member to various unions gives the compiler permission to
insert padding that is otherwise not possible when a packed struct
occurs immediately before a union containing only packed members. In
particular, with structured replies, it is worth ensuring that
sbuf.sr.payload.offset_data.offset falls on a 64-bit alignment.
Note that sbuf.or does not need this latter treatment (currently,
(sbuf.or.payload.export.exportsize is the only uint64_t in that
particular payload union, but does not occur at a natural alignment to
begin with); but it is also worth remembering that option negotiation
is not in the hot path the way sbuf.sr is.
Actually testing the alignment change from adding align_ members is
harder to do, especially without C11's <stdalign.h>, in part because
on 32-bit platforms where uint64_t is only 4-byte aligned (without gcc
-malign-double), there is no change to layout. But in my
investigation under gdb on x86_64, inserting the otherwise-unused
align_* members changed both offsetof(struct nbd_handle, sbuf) % 8 and
(offsetof(struct nbd_handle, sbuf.sr.payload) - offsetof(struct
nbd_handle, sbuf)) % 8 from 4 to 0, which is what I wanted.
Not touched here: gcc's -Wpacked says several (but not all) of our
structures in that file are already naturally aligned, where adding a
packed notation can actually cause slower code when embedding that
type in a larger structure (exactly what we're doing when combining
those structs into sbuf), when the compiler has to prepare for
unaligned access even if the struct would otherwise be aligned.

[libnbd PATCH] internal: s/handle/cookie/ to match NBD spec
by Eric Blake
Externally, we have been exposing the 64-bit opaque marker for each
NBD packet as the "cookie", because it was less confusing when
contrasted with our 'struct nbd_handle *' holding all libnbd state.
It also avoids confusion between the noun 'handle' as a way to
identify a packet and the verb 'handle' for reacting to things like
signals. Upstream NBD changed their spec to favor the name "cookie"
based on our recommendations[1], and so now we can get rid of our last
uses of the old name.

[libnbd PATCH] maint: Drop useless casts
by Eric Blake
While reviewing the previous whitespace-only patch, I noticed several
casts that are semantically unnecessary in C:
- converting pointers to and from void* does not need a cast except
for function pointers or when also casting away const (different
from C++ where casts to or from void* are required for type safety);
includes cases like python PyCapsule code which uses void*
- casting away const on a string literal (in C, string literals are
typed 'char *', different from C++ where they are 'const char *';
that said, C says it is still undefined behavior to modify their
contents, so string literals should generally be only assigned to
'const char *' variables or passed to functions that promise not to
modify contents); includes cases like ocaml's struct
custom_operations using 'const char *' as its member type (where
casting away const just to re-add it is pointless)
- casts used to document what would otherwise be implicit type
conversions when assigning to integers of a different type or
passing function parameters not through varargs. While this can be
useful for documentation purposes, it can also mask bugs when the
cast uses the wrong intermediate type only to be implicitly
converted back to the destination type, and it is often easier to
use optional compiler warning flags to catch instances of unintended
truncation or sign extension by implicit conversions.
Minimizing semantically unneeded casts lets the remaining casts stand
out for why they are necessary: casting aways const, casts between
pointer aliases (such as struct sockaddr*, char* vs unsigned char*,
...), and scalars passed through vargs in printf-like functions.

[libnbd PATCH] maint: pick consistent spacing style for casts
by Eric Blake
We are inconsistent on whether a cast operator should be separated
from its argument by a space. As a unary prefix operator, casts bind
with relatively tight precedence, where only postfix operations
(including function calls) come higher. We generally don't use a
space after other prefix operators (*, &, ~, and unary - tend to not
be followed by space; we are less consistent on !, but that would be a
separate patch).
Furthermore, we've already decided (in commit b5101fbc) that we prefer
spaces before function invocations. At the time, discussion on the
list[1] pointed out that thanks to the complexity of C with its
context-sensitive parsing needing to know whether an identifier is a
type name, you would be able to tell the difference between a
2-argument function call with two parameters through a function
pointer (or intentional function-like macro suppression):
(foo) (bar, baz)
from the (admittedly rare) application of a cast operator to the
results of a comma operator:
(foo)(bar, baz)
if we consistently avoid spaces after casts.
Determining cast operators is not always trivial, but the regex used
below seems to have a pretty low false positive rate (lines it selects
usually are casts and not in a comment line), and can be modified by
removing the space to see where we already had casts without a
space. (Obviously, I can't tell how many false negatives there are of
casts I missed out on). While this changes more lines than would be
done by instead always using a space in a cast, it is still manageable
to do a bulk change.
$ git grep '\(_t\|int\|long\|signed\|char\|\*\)) [a-zA-Z0-9&"]' -- \
'**/*.[hc]' '**/*.ml' | grep -v '^ */\?\*'
'git show -w' shows that this change is whitespace only.
