tools: hv: lsvmbus: change shebang to use python3

2024-08-03T00:01:55+00:00

In many modern Linux distros, running `lsvmbus` returns the error:
```
/usr/bin/env: 'python': No such file or directory
```
because 'python' doesn't point anywhere.

Now that python2 has reached EOL as of January 1, 2020 and is no longer
maintained[1], these distros have python3 instead.

Also, the script isn't executable by default because the permissions are
set to mode 644.

Fix this by updating the shebang in the `lsvmbus` to use python3 instead
of python. Also fix the permissions to be 755 so that is executable by
default, which matches other similar scripts in `tools/hv`.

The script is also tested and verified that is compatible with
python3.

tools: hv: suppress the invalid warning for packed member alignment

2024-05-28T05:27:35+00:00

Packed struct vmbus_bufring is 4096 byte aligned and the reporting
warning is for the first member of that struct which shouldn't add
any offset to create alignment issue.

Suppress the warning by adding -Wno-address-of-packed-member flag to
gcc.

hv/hv_kvp_daemon: Handle IPv4 and Ipv6 combination for keyfile format

2024-04-10T21:25:40+00:00

If the network configuration strings are passed as a combination of IPv4
and IPv6 addresses, the current KVP daemon does not handle processing for
the keyfile configuration format.
With these changes, the keyfile config generation logic scans through the
list twice to generate IPv4 and IPv6 sections for the configuration files
to handle this support.

Testcases ran:Rhel 9, Hyper-V VMs
              (IPv4 only, IPv6 only, IPv4 and IPv6 combination)

hv/hv_kvp_daemon: Some small fixes for handling NM keyfiles

2023-11-10T23:27:46+00:00

Some small fixes:
 - lets make sure we are not adding ipv4 addresses in ipv6 section in
   keyfile and vice versa.
 - ADDR_FAMILY_IPV6 is a bit in addr_family. Test that bit instead of
   checking the whole value of addr_family.
 - Some trivial fixes in hv_set_ifconfig.sh.

These fixes are proposed after doing some internal testing at Red Hat.
