[pve-devel] [PATCH pve-storage/pve-manager v3 0/4] fix #623: show isos/vztmpl/snippets in subdirs

[Noel Ullreich]

This patch fixes #623, allowing isos/vztmpl/snippets in subdirectories.
This feature is opt-in and can be set from the API, web interface or
with `pvesm`.

I addressed the security concerns raised by Fabian, now parent
directories in the path (i.e. `/my/path/../somewhere/`) are forbidded.
I have kept the permission to use symlinks, however, if this is a
security issue, symlinks can easily be forbidden as well. This,
however, would be a breaking change.

parts of the tests as well as the regex for checking, if a `/../` is in
the path have been taken and/or adapted from an older patch that was
never merged:
https://lists.proxmox.com/pipermail/pve-devel/2020-May/043622.html

This is a complete rework from v1, so I don't see a point in writing
what the differences are. It's all different.

----
changes from v2:
* rebased so that applying with new structure in pve-storage works 
(/PVE was moved to /src/PVE/)
* fixed the path of the volid for snippets in Pluggin.pm (thanks @Markus)
