[libnbd PATCH v2 0/3] Improve type-safety of ocaml/golang getters
by Eric Blake
Well, the golang changes (patch 1 and 2/3 of v1) were already
committed, all that was left was the OCaml changes. I'm a lot happier
with how things turned out with an UNKNOWN constructor in the OCaml
variants.

[PATCH nbdkit NOT WORKING 0/2] vddk: Relax threading model.
by Richard W.M. Jones
I believe this roughly implements Nir's proposal here:
https://www.redhat.com/archives/libguestfs/2020-August/msg00028.html
Unfortunately it doesn't work for me. It actually slows things down
quite a lot, for reasons I don't understand. Note the adjustment of
the pool-max parameter and how it affects the total time. The results
are quite reproducible.

I'm still investigating this. Could be a simple coding error somewhere.

[libnbd PATCH 0/3] Improve type-safety of ocaml/golang getters
by Eric Blake
Natural fallout after my recent testsuite additions that fixed a
couple of ocaml bugs in the setters. However, on at least the OCaml
code, I'm not sure what we should do if a newer libnbd ever returns a
bit that an older NBD.mli was not expecting at the time the OCaml
compiler ran (see below). I'm also not sure if there is a more
efficient way to avoid outputting Val_FOO() converters for types not
referenced in REnum/RFlags than my hack of __attribute__((unused)).
Hence I'll wait for a review on these.
Now, for the future compatibility lesson, promised above.
nbd_get_handshake_flags is documented as potentially returning
additional bits from a newer libnbd than what the current client code
was compiled against. How? Let's say a future NBD protocol addition
adds LIBNBD_HANDSHAKE_FLAG_64BIT (as that one might actually be a way
that we implement 64-bit requests...). Presumably, once the NBD
protocol defines it and future libnbd implements it, then future
libnbd will default to setting that bit during nbd_create(). An older
C client that did:
flags = nbd_get_handshake_flags (nbd) & ~LIBNBD_HANDSHAKE_FLAG_NO_ZEROES;
nbd_set_handshake_flags (nbd, flags);
will still run (even though flags contains a bit that was not known at
the time the C app was compiled, the libnbd call that checks that all
input bits are known is from the newer libnbd that recognizes
LIBNBD_HANDSHAKE_FLAG_64BIT as valid). But an OCaml client compiled
against the older interface has no OCaml value to represent the new
bit from the getter, nor any way to specify that new bit to the setter
that is expecting a list of only the old variant type. Maybe we want
the generator to produce a full list of 31 variants per 'flags' type,
using placeholders for all bits not currently in use, to make it
easier to receive an unknown bit from the getter and turn around to
re-supply it to the setter? In such a setup, libnbd would still be
rejecting input of out-of-range bits in relation to what libnbd knew
at its compilation time.

libnbd completion callback question
by Eric Blake
I noticed while reading the code that we have a documentation hole that
may cause memory leaks for clients that are unaware, in relation to
completion callbacks.
The situation arises as follows: for all commands with a completion
callback, I checked that the code has clean semantics: either
nbd_aio_FOO() returns -1 and we never call the callback cleanup, or
nbd_aio_FOO() returns a cookie and we call the callback cleanup when the
command is retired. And since completion callbacks can only ever be
passed to nbd_aio_FOO() functions, it is simple enough to document that
when nbd_aio_FOO() fails (possible when calling them while the state
machine is in the wrong state, or with invalid flags, or a command that
the server is unwilling to accept - all things we can check client-side
without traffic to the server), then the callback function was NOT
registered, and the user must clean any resources then and there to
avoid a leak. Only when nbd_aio_FOO() succeeds will the responsibility
for cleanup be handled by the callback.
But for nbd_block_status and nbd_pread_structured, we have a second
callback. And _these_ callbacks have a problem: we can return -1 for
two different reasons, either because the command was never attempted
(nbd_aio_FOO failed) and so the callback will never be cleaned, or
because the command got sent to the server and the server failed it (the
callback WILL be cleaned). As this is ambiguous, it risks being a
memory leak. So I think we have a bug in our code, and need to
strengthen our promise of whether the cleanup callback will be called,
regardless of success or failure, while still minimizing any incompat
changes that might cause a double-free for existing clients.

[RFC libnbd PATCH 0/2] Add knobs for client- vs. server-side validation
by Eric Blake
We have been inconsistent on how much we reject client-side without
even consulting the server, vs. how much we depend on the server to
detect failure (even if our request can be deemed undefined per NBD
protocol). I'd like to change it so that by default, we reject as
much as we can client-side for less traffic, but where the user can
also change things on the fly for server-side integration testing.
My remaining question, then, is how many knobs to expose initially?
As written, I've only given two knobs, but make the case in each patch
how it could easily be split into four knobs if we think the finer
granularity is worthwhile.
A future knob for block-size validation would also make sense,
especially given the recent addition of support for querying server
minimum block size constraints (although I'd like to finish my work on
getting nbdkit to advertise block constraints to make that easier to
test...).

Weird results from g.sh()
by Sam Eiderman
Hi,
I'm using libguestfs 1.42,
When I run the following python3 commands on a rhel7.8:
print(g.ls('/sys'))
print(g.sh('ls /sys'))
I get:
[]
block
bus
class
dev
devices
firmware
fs
hypervisor
kernel
module
power
It seems that g.ls('/sys') is chrooted correctly.
But g.sh('ls /sys') isn't.
I came across this behavior when I used g.command(['grub2-mkconfig', '-o',
'....']) on rhel7.8 and it didn't produce the correct linuxefi/initrdefi
entries in grub, since in rhel7.8 the uefi detection algorithm is checking
in bash '[ -d /sys/firmware/efi ]'.
https://src.fedoraproject.org/rpms/grub2/blob/71e0fb4ea646071ec86e4a65bb2...
I thought I could simply g.mkdir_p('/sys/firmware/efi') - but that created
a fake dir in my chrooted environment, where grub2-mkconfig somehow was
inspecting the real /sys as demonstrated in the above 'ls' example.
Any ideas on why sh jailbreaks the chroot? is /sys set through some
environment variable?
Thanks!

[PATCH v2v] v2v: Allow output to block devices (RHBZ#1868690).
by Richard W.M. Jones
We previously implicitly supported writing to block devices instead of
local files, but there were several problems:
* Block devices could be deleted, especially if virt-v2v failed during
a conversion.
* Block devices could be overwritten by a file with the same name,
although I believe this is just an observed consequence of the
previous point, or at least I was not able to reproduce this until
virt-v2v failed for another reason and then I noticed that because
the block device was deleted, the next run overwrote it with a file.
* It was not documented anywhere how to do it.
This commit makes the small code change needed to allow virt-v2v to
write to a block device, only for existing outputs which write to
local files (ie. using TargetFile). Also it avoids deleting block
devices accidentally on failure.
Note this commit intentionally does not prevent you from writing qcow2
to a block device. RHV uses this so it is a thing that people do.
