I’m not a complete newb, but I’m no expert either, but please don’t think I’m being critical…I’ve just come across something I’m not used to (I used Ubuntu for years but only as a set top box & laptop, never an always on server so I never thought to, or even knew if it was possible to, validate a checksum post-install)…& I found some FUD on youtube when googling for answers.
Anyway, I know some, if not most/all, of these files likely get modified during normal use (changing user name, adding a user or group, etc), but the fact that things like shell, pam, pamac, & (especially) that the raspi firmware & manjaro rpi modules are listed as altered with mismatched hashes has me curious & a little concerned. So could someone please take a glance at the list below (relevant output of pacman -Qkk) & tell me if I should be worried or not?
Plus, those mirrors with mismatched checksums seems to add a touch of credibility (at least to the uninitiated) to that youtube video I found. It draws attention to (or makes allegations of) recent security related faux pas (ssl expiry, shipping packages prior to release by upstream-ie openssl vulnerability, etc) by Manjaro Gmbh-corp (the ytber didn’t blame the dev team, but speculated the root cause likely fell from above). Whatever, anyway, sorry, too long…
Also, and this is probably my inexperience with selinux, but…that and iptables (which I am more familiar with), will not persist through a reboot (warnings or disabled in dmesg)…& may not ever even initialize (not seen in htop), but I realized this just now so I haven’t done much digging…prolly something I’m doing unless the issue above is real & impacting this.
TLDR; will someone with more experience than me tell me if what is pasted below is any cause for concern
