A new roadmap is on the web… Solaris 11.5 as Solaris.next and new Sparc M8+ chips are planned for 2020/21…
Good new for the best operating system on the world 😉
Oh… I am really looking forward to getting more information about that new Solaris 11.4 dashboard and internal stats command. Just a quick view with:
# svcadm enable webui/server
gives you a nice BUI to click around at https://<IP:6787> with some drilldowns and nice graphs… (btw; that the old sun management console port 🙂 )
not there what fishwork’s ZFSSA BUI can do, but I hope some of that analytic drilldowns will also be possible on native Solaris soon.
Quick screener from my installation, but well… right now the ldom does nothing…
This might be a good “single pane of glass” view to get a health report without any additional frameworks like nagios or similar external tools. I am really interested how this will look and feel on a production server…
On the first look, you could do a lot… but I need a server who is doing something to really click around… will have to find some testing stuff 🙂
A lot to customize if you want that…
If you missed it; great news in the last days around Solaris 11.next… a public BETA for 11.4 is out:
I am ready to install it on my demo boxes… great features to test… will post some outcomes soon 🙂
In the last couple of weeks the whole IT was shocked getting news about security issues based on basic CPU architecture design covering “all” processor vendors… Spectre (CVE-2017-5753 and CVE-2017-5715) and Meltdown (CVE-2017-5754) vulnerabilities affected XEONs, AMD, POWER and ARM chips, but also SPARC uses similar features like all others. Spectre and Meltdown are different variants of the same fundamental underlying vulnerability, if exploited, allow attackers to get access to data previously considered completely protected. That affects chips manufactured in the last 20 years. Speculative execution to predict the future and out of order execution were implemented by Sun on their SPARC T3 chips (eg.: T3-1; GA November 2010, LOD September 2012).
Solaris never had kernel pages mapped in user context on SPARC. That’s the reason why I do not think Meltdown affects SPARC at all. Also Oracle mentioned “Oracle believes that Oracle Solaris versions running on SPARCv9 hardware are not impacted by the Meltdown”. But it could happen on Solaris x86 as far as I understood.
Well, starting with T3 (S3 core) Oracle introduced speculative and out-of-order execution in the S3 pipeline. Prediction algorithms and deepness of the prediction buffers differs not only between vendors but across CPU generations. So it might be tricky but still possible to attack SPARC systems. Right now there is no public known attack for Solaris SPARC. Oracle says “Oracle believes that certain versions of Oracle Solaris on SPARCv9 are affected by the Spectre vulnerabilities.”
There are no public patches from Oracle at the moment to fix that issue, but an own MOS document for SPARC:
Oracle Support Document 2349278.1 (Oracle Solaris on SPARC and Spectre (CVE-2017-5753 and CVE-2017-5715) and Meltdown (CVE-2017-5754)) can be found at: https://support.oracle.com/epmos/faces/DocumentDisplay?id=2349278.1
All other Oracle products could be found at:
Oracle Support Document 2347948.1 (Addendum to the January 2018 CPU Advisory for Spectre and Meltdown) can be found at: https://support.oracle.com/epmos/faces/DocumentDisplay?id=2347948.1
Let’s see what will happen in the next days… stay tuned….
After a default Linux (in my case Oracle Linux 7.4) installation you won’t see anything after grub finished with “start /HOST/console”
