status: handle ds not defined in status.json (#1876)
Handles any situation where `status.json` does not yet contain
datasource information, by gracefully fulfilling a
`datasource=None` in `StatusDetails`.
net: skip duplicate mac check for netvsc nic and its VF (#1853)
When accelerated network is enabled on Azure, the host presents
two network interfaces with the same mac address to the VM:
a synthetic nic (netvsc) and a VF nic, which is enslaved to the synthetic
nic.
The net module is already excluding slave nics when enumerating
interfaces. However, if cloud-init starts enumerating after the kernel
makes the VF visible to userspace, but before the enslaving has finished,
cloud-init will see two nics with duplicate mac.
This change will skip the duplicate mac error if one of the two nics
with duplicate mac is a netvsc nic
The manpages for mkfs.ext4, mkfs.xfs, and mkswap all indicate that
options should be passed *before* the device name but cc_disk_setup
passed them after the device name - in the case of mkfx.ext4 a
"fs-size" can be passed after the device and that is what the
"-L disk3-fs2" option is being misintepreted as.
This PR ensures that the device name is passed last. The underlying
issue appears to be due to a different in behaviour between glibc and
musl where glibc "helps" applications by re-ordered command-line
parameters by musl does not[1] as it sticks to POSIX spec.
This PR also modifies 2 testcases to cater for this change in the code,
adds a note to disk_setup to clarify that when creating a swap partition
a fs_entry also needs to be specified so that mkswap is run, adds to the
examples how to specify a non-default partition type (i.e. for swap),
and modifies the description for disk_setup to clarify this.
