Yum updates not respecting excludes, if excludes have wildcards.

[sharkannon]

It seems that according to the docs, the "Exclude" function on yum_updates should be the same as
yum update -x <package> or yum update --exclude <package>, however both those syntax support wildcards. When I try to use wildcards in our excludes, the excludes are ignored and the packages we're trying to exclude are updated. If I put in the specific package name, things are ignored as expected, however this is not always the best scenario, as some packages have version numbers (of dependency packages) embedded in their name, so a wildcard is required to properly exclude them.

Examples

Yum update (no excludes)

Yum update to exclude google-cloud-sdk

yum update -x google-*
Loaded plugins: fastestmirror
Loading mirror speeds from cached hostfile
No packages marked for update

yum update --exclude google-*
Loaded plugins: fastestmirror
Loading mirror speeds from cached hostfile
No packages marked for update

That's how it should work, but when I add google-* to the excludes in OSPatch Management, google-cloud-sdk gets updated.

Output of log:

Running in dryrun mode, not updating 1 packages: ["google-cloud-sdk x86_64 395.0.0-1"]

The above output indicates that the package would be updated if it wasn't in dryrun.
