I recall that before "Code Red" (anyone remember that?) there was no antivirus worth talking about and no concern about security as such. The Shellshock exploit probably does two things. Firstly it raises awareness of many admins as regards security of Linux systems and it encourages hackers because they realise that there is now (and actually always has been) a target in Linux systems. It may be Linux's "Code Red". There are definitely more exploits out there. Not all Linux admins are security aware, just as many are not backup aware. Many think that Linux systems are secure by default. Many will "get around to security" some time.

[CentOS] Conduct on the CentOS List
-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 The recent anti-social content on the list including threats and support of harassment needs to stop immediately. The CentOS Board will work with the list admins to enforce moderation and if needed removal and bans from the list should people continue this behaviour. This is a large, diverse, and respected community and none of us should need to tolerate any form of uncivilised behaviour, such as harassment and threats. The topic of harassment and online threats has been at the top of mind lately, and in light of the conversation we would like to make it clear that the CentOS Project is not a place for abuse or hostility. There is no excuse for this behaviour, no matter what the intention. Discouraging and banning anti-social behaviour in the CentOS Project has been part of an ongoing effort for a while, and now we feel it's time to come forward with a clear statement. As with any open community, we have disagreements on technical matters. It's part of the natural exchanges needed for a vibrant community, but we must keep the discussions civil. Have consideration and respect for other people. The power of an open source project is in the community. If the community gets broken, the project loses its fundamental reason-for-being. Code alone does not make open source, and community is made through people treating each other with respect. * Do not make personal attacks * Do not threaten people * Do not harass people * Do debate ideas on the merits of the idea alone * Do help each other keep a civil tone while remaining civil * Do treat others with respect In your communication on CentOS Project forums such as IRC, mailing lists, Web forums, or any other medium, we will not tolerate personal attacks, threats, or harassment of any individual or group. We reserve the right to moderate or ban anyone who violates our guidelines without notice or discussion. Thank you for your attention to this important matter. - -- Karanbir Singh, CentOS Project Leader on behalf of the CentOS Project Board -BEGIN PGP SIGNATURE- Version: GnuPG v2.0.14 (GNU/Linux) iQEcBAEBAgAGBQJUNxUDAAoJEI3Oi2Mx7xbtDnsH/0UqAu2xN8M6pxkkx+oS8geX 8rFJpsHt2tYB06lVrBXrXUsUx7LzGcBe78C3ZnTUBVjG9H7kLEnKjXTDk4JObiH6 e2FMTEgBc62tiLFrCZEYIFgYrfcRSg8PciZQbr4DQ9kd/Q3TbQvzcs6yAU8xZn75 yJ1tRadRbXNZzz2dwgNMVfcRpVBTWSogivRvYtYzx1mB0EPiFzCrTQ8Cw9CqFilx DADtJFiIBuuUhfhNV3iOVIgmgSBBnoaPqUsru0PSs6UZlxKLT0R37oiE/ZTPCLCY 2GHELWMJ3R9UMvL+oQvP0dhOtgLUv+sX592aCaHAruGUGIfBCI7TO2aR0At2hYQ= =3AX4 -END PGP SIGNATURE- ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

I was going to post about this earlier, but got distracted ... Add-ons are totally broken on C5/ff31. All of them download, some of them continue to install (without the installation progress bar showing any signs of it), and for most add-ons, nothing happens after that. Sometimes, the add-on will install when the manual installation option is selected and the downloaded /tmp/xxx.xpi file chosen, but most of the time this does not work either. This also prevents updating of add-ons. What does seem to work is to log into a C6 box to install add-ons, no such problems there. ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

"human factor" means it is extra work for someone who was already using a linux distribution because it did what they wanted - which doesn't seem good to me either.

ZFS snapshots can however be run on a per second basis which is quite neat! What ever you choose to do you would probably want to use mysql binary replication anyway so having a completely sync filesystem replica is probably not too much of a problem.

Not that simple. Smaller things none of which on its own make you make fundamental decision just accumulate, so after some critical mass you are there, the decision is made. I probably will not remember all of them, and definitely not in the order of their arrival. 1. SELinux (it doesn't not pass _my_ "security has been enhanced" estimate. It can be turned off on the fly, therefore it is as if it doesn't exist. It adds tens of thousands of lines of code to the kernel, thus increasing chance of bugs and deteriorating security. And once my estimate was confirmed: "critical security update of SELinux"...) 2. The need to reboot linux box often (on average every 45 days in my observation...). I know, there are workarounds to patch on the fly... 3. Firewalld. I'm tempted to say: the philosophy it's based on is flawed. Hey, this is our institutional internal network which is behind strict firewall, so we consider it "safe" zone... Nope. Wherever is the machine that _you_ do not administer, you better do not consider it "safe" or "secure". It uses the same iptables kernel module, right? And you can switch to using iptables instead if it, right? Only one day you end up running distro with stripped this, stripped that... Small thing in itself as I said. 4. Systemd. ("If it ain't broke, don't fix it"). I don't want to start flames again... And things add up gradually till you realize this. If I were willing to run M$ Windows I would pay for it, and will curse it legitimately as I paid for it and my money entitles me to curse it. Now I run free open source system courtesy of uncounted number of generous developers. I should be grateful to them and tolerate new routes they take - which is usually their only reward for their work... So, when I can not tolerate it any more (... accumulated above critical mass), I just go to another also open source system, thank goodness, they still do exist...

Well, the upstream patch, at least as it is written now, would require them to back out their patches to apply. But regardless if whether or not they fix the segfault issue, that is NOT a security issue or exploitable. It might possibly be a Denial of Service mechanism, I guess. The place to address this is on the bugzilla entry though.

I wonder why personal implications are communicated without explained reasons (because all are screaming doesn't mean its valid). "Changes" have inherent implications by it self - it doesn't matter what was the change.
