Rewrite write_image.sh in Python

2021-05-18T12:45:13+00:00

Enable out-of-order writes when writing whole disk images

Per documentation it improves performance when using -O host_device.

Add a call to "udevadm settle" in write_image.sh

2021-04-20T16:48:46+00:00

After GPT and MBR are destroyed systemd-udevd gets triggered
which may hold /dev/sda open preventing qemu-img from writting
its image.

Increase the memory limit for qemu-img

2021-03-02T11:38:57+00:00

We appear to be bumping up against this limit when deploying
RHCOS images(currently 977MB). Curiously the problem isn't
happening all the time but increasing the limit eliminates it.

This limit was intruduced to guard against a malicious image
allocating an arbitrary amount of memory. Nothing else runs
on hosts when IPA is running so we should be ok bumping up
the limit.

Clear GPT and MBR headers with dd to avoid sgdisk CRC errors

2018-08-08T16:40:22+00:00

This change adds a dd before the existing sgdisk -Z command to
workaround CRC verification errors.

Fix for fatal error when GPT was used and only MBR was cleaned

2018-05-17T10:51:55+00:00

You can generate this error if after having provisioned a node
using GPT partitioning, you clean its MBR using say
dd if=/dev/zero bs=1024 count=1 of=/dev/sda
and then cleanup all Ironic/Bifrost informations to get it
reprovisioned.
In this case sgdisk -Z returns an error and last_error field
in Ironic contains:
Error writing image to device: Writing image to device
        /dev/sda failed with exit code 2
Caution: invalid main GPT header, but valid backup;
        regenerating main header\nfrom backup!\n
        \nInvalid partition data!\

Limit memory usage when running qemu-img convert

2017-01-19T18:01:30+00:00

This patch is limiting the memory address space to 1 GiB when invoking
qemu-img convert. The qemu-img command can be exploited so we better
play on the safe side (See: bug #1449062).

Add bash scripts style checking for IPA

2016-11-09T22:14:40+00:00

Updated file tox.ini allows to check code style in all ".sh" files
included in Ironic Python Agent. Checking can be invoked by calling either
"tox" or "tox -e pep8".
