check-pacman-mtree check pacman db missmatch size/md5/sha256/symlink

AUR package https://aur.archlinux.org/packages/check-pacman-mtree/
last version 0.7 (can check for symlink also)

This script should help to locate the files that changed (size/md5/sha256/symlink) , right now pacman -Qkk can not verify md5/sha256. For example to see if are hacked or if your hdd is borked.

NOTE : this will work *ONLY* for packages having mtree file (/var/lib/pacman/local/$pkg/mtree)

NOTE2: need testing for 32bit (tested only on x86_64) , also for prelink users.

DIFF means filesystem and pacman db is not the same
EXTRA_MTREE = item missing from filesystem
FAIL = script can not open mtree file for respective pkg or open file/symlink to check
NOTE: script is not checking folders/sockets/etc ,also is not check for uid/gid/mtime/perms missmatch

Examples of usage

[root@archlinux-build ~]# check-pacman-mtree.lua
usage: /usr/bin/check-pacman-mtree.lua [ -a | pkg1 pkg2...] [-v | -vv] )
-a  = all pkgs
-v  = verbose(include size/md5/sha256)
-vv = even more verbose(show PKG= lines)

check all packages:

[root@archlinux-build ~]# check-pacman-mtree.lua -a
DIFF pkg=lighttpd-1.4.35-1 file=etc/lighttpd/lighttpd.conf
DIFF pkg=syslog-ng-3.6.1-1 file=etc/syslog-ng/syslog-ng.conf
DIFF pkg=glibc-2.20-6 file=etc/locale.gen
EXTRA_MTREE pkg=systemd-211-1 file=usr/lib/systemd/system/console-getty.service
EXTRA_MTREE pkg=systemd-211-1 file=usr/lib/systemd/system/getty.target
EXTRA_MTREE pkg=systemd-211-1 file=usr/lib/systemd/system/getty@.service
...

Re: check-pacman-mtree check pacman db missmatch size/md5/sha256/symlink

A pacman -Qkk that identifies which files have been modified? This is something I find useful. It looks like a more specialized tool to do what I wanted some time ago.

NOTE : this will work *ONLY* for packages having mtree file (/var/lib/pacman/local/$pkg/mtree)

Are there any packages that don't have this file?

I did a quick:

pacman -Q | wc -l

and

 ls /var/lib/pacman/local/*/mtree | wc -l

And got the same numbers, which indicate that all packages I have installed have this file.

Not in the official repos, as far as I can tell: https://www.archlinux.org/todo/mtree-rebuilds/

Some third-party repos may still have mtree-less packages, and any unsupported (AUR) packages built prior to pacman-4.1 will not have one.

Re: check-pacman-mtree check pacman db missmatch size/md5/sha256/symlink

some old packages may not have mtree file, if you got same numbers then it means is good
Also the script will say if some pkg do not have MTREE file
version 0.5 of the script will tell if some pkg do not have mtree file

[root@silver ~]# check-pacman-mtree.luajit -av
...
FAIL_MTREE_FILE pkg=xpdf-3.04-2 gzopen /var/lib/pacman/local/xpdf-3.04-2/mtree: No such file or directory
[root@silver ~]#

My testing was done only on x86_64. whoever and willing to test is on 32bit pls provide script feedback
Also those that use prelink .
