migration: add static analysis tool to check vmstate compat
v3 cover migration: add static analysis tool to check vmstate compat
Hello,
v3:
- Python script returns an error code: 0 if no errors, positive for the number of errors identified.
v2:
- Tabs->spaces (Dave Gilbert)
- Several changes to the python script to make it more python-like (Vitaly Kuznetsov)
- Don't store the empty fields created by VMSTATE_VALIDATE in the json output
This series adds a static vmstate checker to check for breakage of live migration by analyzing the vmstate information between different QEMU versions.
In patch 1, QEMU is modified to add a -dump-vmstate commandline option, which takes a filename as the argument. When invoked, QEMU dumps the vmstate info in JSON format for the current machine type to the file. This patch is loosely based on a version from Andreas Färber.
This JSON file is then fed into the Python script introduced in patch
2. The script takes 'src' and 'dest' arguments, indicating the direction of migration. The script then performs a series of checks and spews out information on inconsistencies it finds in the data.
Two stripped-down versions of JSON dumps are included in this patchset (patch 3).
Patches 4 - 18 contain modifications to those dumps, to show the checks that are performed by the script. The result of running the script against the final version of those files is appended below.
The checks are to be performed for a particular machine type, and comparing different machine types is bound to turn up false-positives:
e.g.
(in a qemu 2.0 tree):
./x86_64-softmmu/qemu-system-x86_64 -dump-vmstate qemu-2.0.json
(in a qemu 2.2 tree:)
./x86_64-softmmu/qemu-system-x86_64 -dump-vmstate -M pc-i440fx-2.0 \
qemu-2.2-m2.0.json
./scripts/vmstate-static-checker.py -s qemu-2.0.json -d qemu-2.2-m2.0.json
should not show any output.
The idea is to include this script in 'make check', ensuring new commits don't break migration.
Later, this script can also be baked into the release process: vmstate dumps for released versions of qemu for various machine types can be stored in a directory in the tree. At the time of freezing the tree for releases, (like -rc2), the dump for the current release can be updated. A policy that says "No more live migration-breaking changes can be accepted post -rc2" can be put in place. Also, for checks for older machine types on the current tree with the saved dumps should not indicate any regressions.
I expect there to be a few false positives at the start (though there aren't any right now). The script will keep evolving, though, to include new scenarios, to make it more helpful.
A later project would be to also store other guest-visible information and use that output for more checks (including lspci output from inside guests).
As mentioned earlier, this is the result of running the script against the sample json data included in this patchset:
$ ./scripts/vmstate-static-checker.py --src ./tests/vmstate-static-checker-data/dump1.json --dest ./tests/vmstate-static-checker-data/dump2.json Section "usb-kbd" Description "usb-kbd" Field "kbd.keycodes" size mismatch: 4 , 2 Section "PIIX3-xen" Description "PIIX3": minimum version error: 1 < 2 Section "PIIX3-xen" Description "PIIX3": Entry "Subsections" missing Section "tpci200": Description "tpci200" missing, got "tpci2002" instead; skipping Section "megasas", Description "PCIDevice": expected field "irq_state", while dest has no further fields Section "SUNW,fdtwo" Description "fdc": version error: 2 > 1 Section "SUNW,fdtwo", Description "fdrive": Subsection "fdrive/media_rate" not found Section "fusbh200-ehci-usb" version error: 2 > 1 Section "fusbh200-ehci-usb", Description "ehci-core": expected field "usbsts", got "usbsts_pending"; skipping rest Section "intel-hda-generic", Description "intel-hda", Field "pci": missing description Section "cfi.pflash01": Entry "Description" missing Section "pci-serial-4x" Description "pci-serial-multi": Entry "Fields" missing Warning: checking incompatible machine types: "pc-i440fx-2.1", "pc-i440fx-2.2" Section "fw_cfg" does not exist in dest
$ echo $? 13

PATCH v3 1/18 migration: dump vmstate info as a json file for static analysis
This commit adds a new command, '-dump-vmstate', that takes a filename as a parameter. When executed, QEMU will dump the vmstate information for the machine type it's invoked with to the file, and quit.
The JSON-format output can then be used to compare the vmstate info for different QEMU versions, specifically to test whether live migration would break due to changes in the vmstate data.
A Python script that compares the output of such JSON dumps is included in the following commit.

PATCH v3 2/18 vmstate-static-checker: script to validate vmstate changes
In reply to Amit ShahThis script compares the vmstate dumps in JSON format as output by QEMU with the -dump-vmstate option.
It flags various errors, like version mismatch, sections going away, size mismatches, etc.
This script is tolerant of a few changes that do not change the on-wire format, like embedding a few fields within substructs.
The script takes -s/--src and -d/--dest parameters, to which filenames are given as arguments.

Hello,
v3:
- Python script returns an error code: 0 if no errors, positive for the number of errors identified.
Returning the error count as $? is unreliable - if you have exactly 256 errors, that gives the same status as if you had success. Does your code guarantee non-zero return in that case?

No; any good ideas for this, then? Just limit to 255, and never bump upwards?
I'm only introducing this so that future integration with 'make check' can be noticed by scripts.

Yes, saturating math (capping at 255) is sufficient; in the normal case, we won't have that many errors.

And for that, all we need is a non-zero status.
