/usr permissions changing for converted packages?

I've just noticed that the permissions on my /usr folder are not owned by root....

However if i grep /usr/bin , i notice these permissions are only set from packages converted with rpm2tgz / deb2tgz, and they somehow changed the permissions of the top level folders. How can i stop the permissions on /usr from messing up in the future when installing packages like this?

Code:

[ricky][2][darkstar|/usr/bin]

$ ls -l | grep ricky

-rwxr-xr-x  1 ricky  users      5504 Oct 25 23:50 kodi

-rwxr-xr-x  1 ricky  users      1830 Oct 25 23:50 kodi-standalone

-rwxr-xr-x  1 ricky  users        322 Sep 22 15:39 skypeforlinux



[ricky][2][darkstar|/usr/bin]

Should be safe to just chown the entire /usr recursively back to root:root ?

Okay i think i messed something up doing "chown root:root -R /usr"...

Code:

[ricky][3][darkstar|~]

$ sudo

sudo: /usr/bin/sudo must be owned by uid 0 and have the setuid bit set

Fixed that one by logging in as root with "su" and then reinstalling sudo, but is there anything else obvious which could be broken after resetting permissions to root?

Every SUID or SGID binary and everything not owned by root:root.

The obvious solution would be to not use those programs since there's no guarantee that an rpm or deb package will work on Slackware. kodi is available on SBo as is skypeforlinux. kodi does require compilation and dependencies, so it is a bit more work to get it, but then it is built against libraries on your computer. skypeforlinux is a simple repackaging of the deb package, but it has been verified to work on Slackware and won't jack up your ownership.

The other option would be to try running those conversion scripts as root, but I don't think it is normally required, so it might've been some option you passed when you ran them that adjusted the ownership of the files (I'm not really familiar with either since I refuse to use them -- I'd much rather repackage it by hand or develop a SlackBuild for it rather than use those).

As for me stupidly chowning my entire /usr, this shouldn't break my system should it?
So far i've only found "sudo" to be a problem so far.

Yes there could be, especially for suid programs.

Below is a Q&D list of files under /usr/ on my system that are not chown root:root ( I also excluded stuff that may not affect your operation ).

Your list will vary because we've installed different packages and I don't have a pure-D Slackware64 14.2 System up-and-running at this minute, but it is a start.

The ones to fix are the ones with one-or more 's' bits set in the permissions column.

HTH.

Alright thanks... i just restarted the xserver, and it failed to load, so i just went and reinstalled xorg* packages, this fixed that.
Rebooted, everything seems fine, except for networkmanager not working. I had to use wpa_supplicant/dhcpcd manually to get online.

I think i'm just going to do this:

Code:

rsync -avP rsync://ftp.osuosl.org/slackware/slackware64-current/ .

And then reinstall/upgrade every package from there. This should fix all of these problems right?

coralfang --

Yep, that outta do it :)

-- kjh

Ok, lesson learned:
DO NOT RECURSIVELY CHOWN TOP LEVEL DIRECTORIES UNDER /

Took a while, but after reinstalling every package set to be safe, everything is back working as it should.
In case anyone reads this, having the same problem, you'll want to basically reinstall every package to get back the correct permissions. Seems to be the simplest way to go about doing this, as opposed to looking up each files individual permissions.

Solved i guess, and i'll probably stop installing converted deb/rpm packages in future to avoid this happening again.

Feel free to create a new post on this, because I haven't had any issues with building kodi, although, I'm not running -current. If there is an issue in -current, I'm sure ponce would be happy to incorporate changes to the kodi SlackBuild in his repo.

I built kodi in -current from slackbuilds about year ago without issue, worked fine.
