[libnbd PATCH v2 0/3] Improve type-safety of ocaml/golang getters
by Eric Blake 08 Sep '20

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 08 Sep '20

08 Sep '20

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. $ ./nbdkit -r -U - vddk libdir=~/tmp/vddk-7.0.0/vmware-vix-disklib-distrib user=root password=*** server=*** thumbprint=*** vm=moref=3 file='[datastore1] Fedora 28/Fedora 28.vmdk' pool-max=1 --run 'time qemu-img convert -p -W -m 16 $nbd /var/tmp/out' (100.00/100%) real 1m8.031s user 0m0.112s sys 0m1.560s $ ./nbdkit -r -U - vddk libdir=~/tmp/vddk-7.0.0/vmware-vix-disklib-distrib user=root password=*** server=*** thumbprint=*** vm=moref=3 file='[datastore1] Fedora 28/Fedora 28.vmdk' pool-max=8 --run 'time qemu-img convert -p -W -m 16 $nbd /var/tmp/out' (100.00/100%) real 1m27.790s user 0m0.099s sys 0m1.625s I'm still investigating this.

[libnbd PATCH 0/3] Improve type-safety of ocaml/golang getters
by Eric Blake 07 Sep '20

07 Sep '20

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 07 Sep '20

07 Sep '20

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. -- Eric Blake, Principal Software Engineer Red Hat, Inc. +1-919-301-3226 Virtualization: qemu.org | libvirt.org

[RFC libnbd PATCH 0/2] Add knobs for client- vs. server-side validation
by Eric Blake 07 Sep '20

07 Sep '20

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 06 Sep '20

06 Sep '20

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/71e0fb4ea646071ec86e4a65bb242… 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 03 Sep '20

03 Sep '20

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. --- docs/virt-v2v.pod | 32 +++++++++++++++++++++++++++++ v2v/v2v.ml | 51 ++++++++++++++++++++++++++++------------------- 2 files changed, 62 insertions(+), 21 deletions(-) diff --git a/docs/virt-v2v.pod b/docs/virt-v2v.pod index a00fa8afa..fd0833492 100644 --- a/docs/virt-v2v.pod +++ b/docs/virt-v2v.pod @@ -1412,8 +1412,40 @@ require either a special user and/or for you to source a script that sets authentication environment variables.
