abrt-watch-log -F BUG: WARNING: at WARNING: CPU: INFO: possible recursive locking detected
by Michael H 15 Feb '16

15 Feb '16

Hi All, I've been tuning a server recently and just today this has started to appear in my top/htop output. [root@db1 ~]# ps -aux | grep kernel root 1011 0.0 0.0 212048 4532 ? Ss 13:34 0:00 /usr/bin/abrt-watch-log -F BUG: WARNING: at WARNING: CPU: INFO: possible recursive locking detected ernel BUG at list_del corruption list_add corruption do_IRQ: stack overflow: ear stack overflow (cur: eneral protection fault nable to handle kernel ouble fault: RTNL: assertion failed eek! page_mapcount(page) went negative! adness at NETDEV WATCHDOG ysctl table check failed : nobody cared IRQ handler type mismatch Machine Check Exception: Machine check events logged divide error: bounds: coprocessor segment overrun: invalid TSS: segment not present: invalid opcode: alignment check: stack segment: fpu exception: simd exception: iret exception: /var/log/messages -- /usr/bin/abrt-dump-oops -xtD I had made a few changes to sysctl.conf which I have now reverted and the error still exists. my sysctl.conf contained; vm.swappiness=0 vm.overcommit_memory=2 vm.overcommit_ratio=90 - this was only added this morning because of an 'out of memory' error in postgresql. kernel.shmmax=35433480192 kernel.shmall=2214592512 which I have now removed. Can anyone shine any light on this? A little search on Google mentions faulty memory, I will install memtest today and see what the output is like. Thanks Michael

A repo with latest httpd for http2?
by SternData 13 Feb '16

13 Feb '16

Is there a well-run package repo that has httpd-2.4.17 or mod_http2 (or mod_h2)? I'd like to try out http2 without having to compile my own httpd. -- -- Steve

ananconda update.img creation fails: generated but with wrong python version in /usr/sbin/anaconda contained
by David Copperfield 11 Feb '16

11 Feb '16

Hi all, I've created an anaconda update.img file per instructions at https://fedoraproject.org/wiki/Anaconda/Updates for Centos 7.2. The problem is that the update.img file contains references to python3 (say, file /usr/sbin/anaconda), and so the all installation fails immediately. My question is: what are the steps to create an anaconda update image appropriate for a particular centos release? Thanks a lot. The steps I have performed (to create an update.img) are listed below: 1) find the version of ananconda that centos 7.2 installation media: 21.48.22.56-1. 2) follow the instructions at the above wiki page, and wiki https://fedoraproject.org/wiki/Anaconda. Run the following command (to generate update.img): 2.1 yum -y install git 2.2 git clone https://fedoraproject.org/wiki/Anaconda 2.3 cd anaconda 2.4 scripts/makeupdates -t anaconda-21.48.22.56-1 3) save the generated image to place under .../images directory. >From what I see, all PXE clients did download the new update.img file and merge the changes contained. But because the updated anaconda pointed to python3 instead of python 2.7.5 (the version comes with installation media), the installation process failed immediately. Thanks. Best,David

OpenSwan Drop Out Issue
by John Cenile 11 Feb '16

11 Feb '16

Hello, I'm cross posting this from the OpenSwan mailing list, in case someone here can help. We have two sites connected via OpenSwan 2.6.32-9 on CentOS 5, sharing 6 /24 subnets each (so 12 in total). The problem we're having is completely randomly, be it in the middle of the day, or in the middle of the night (so I don't believe it's traffic related), certain (and sometimes all) routes will drop. They usually recover after a few minutes, but it's still long enough for our monitoring to detect downtime. The configuration we have on each device is: conn site-a keyingtries=0 keylife=1h ikelifetime=8h left=1.1.1.1 right=2.2.2.2 leftsubnets={x.x.x.x/24,x.x.x.x/24,x.x.x.x/24,x.x.x.x/24,x.x.x.x/24,x.x.x.x/24} rightsubnets={x.x.x.x/24,x.x.x.x/24,x.x.x.x/24,x.x.x.x/24,x.x.x.x/24,x.x.x.x/24} pfs=yes auto=start authby=secret dpddelay=30 dpdtimeout=120 dpdaction=hold phase2alg=aes256-sha1;modp1536 phase2=esp ike=aes256-sha1;modp1536 It's mirrored exactly the same on the other side. I have tried changing the dead peer detection timeout to something high (5 minutes), and removing it completely (which I believe defaults it to 30 seconds), neither of which made any difference. I can't see any very obvious errors in the logs, however the most recent drop out produced the following message around the same time: Feb 10 00:53:09 site-b-vpn pluto[30584]: "site-a/5x5" #39: max number of retransmissions (2) reached STATE_QUICK_I1 Feb 10 00:53:09 site-b-vpn pluto[30584]: "site-a/5x5" #39: starting keying attempt 2 of an unlimited number Feb 10 00:53:09 site-b-vpn pluto[30584]: "site-a/5x5" #95: initiating Quick Mode PSK+ENCRYPT+TUNNEL+PFS+UP+IKEv2ALLOW+SAREFTRACK to replace #39 {using isakmp#52 msgid:119495de proposal=AES(12)_256-SHA1(2)_160 pfsgroup=OAKLEY_GROUP_MODP1536} and also Feb 10 00:52:25 site-a-vpn pluto[2414]: "site-b/6x6" #1: ignoring Delete SA payload: PROTO_IPSEC_ESP SA(0xde58eea3) not found (maybe expired) Feb 10 00:52:25 site-a-vpn pluto[2414]: "site-b/6x6" #1: received and ignored informational message Feb 10 00:52:25 site-a-vpn pluto[2414]: "site-b/6x6" #1: ignoring Delete SA payload: PROTO_IPSEC_ESP SA(0xa5298d7d) not found (maybe expired) Feb 10 00:52:25 site-a-vpn pluto[2414]: "site-b/6x6" #1: received and ignored informational message Before we move to another solution, does anyone have any suggestions on what the problem might be? Running a constant ping between the two hosts doesn't drop *any* packets (even when the IPSec connection itself drops out). Thanks in advance.

This repository has begun triggering alerts in my enterprises trend micro solution this morning. centos.firehosted.com/7.2.1511/updates/x86_64/repodata/repomd.xml Any tips on ensuring this repository is never queried by my systems ? It seems to keep getting picked up on freshly deployed vagrants for development at this time. Thanks, Corey Erickson

Measuring memory bandwidth utilization
by Benjamin Smith 10 Feb '16

10 Feb '16

I'd like to know what the cause of a particular DB server's slowdown might be. We've ruled out IOPs for the disks (~ 20%) and raw CPU load (top shows perhaps 1/2 of cores busy, but the system slows to a crawl. We're suspecting that we're simply running out of memory bandwidth but have no way to confirm this suspicion. Is there a way to test for this? Think: iostat but for memory bandwidth instead of disk IO. So far, searching has found intel-cmt-cat-master which isn't supported on our CPU and oprofile which *sounds* like it does what I want from their website but I can't seem to get output that, in any way, tells me what the bandwidth usage is. Any idea?

See: http://www.techrepublic.com/article/erasing-ssds-security-is-an-issue/ The CSE requires physical destruction of these devices through pulverisation or incineration. See: https://cse-cst.gc.ca/en/system/files/pdf_documents/itsg06-eng.pdf The USDOD leaves disposal protocols to the individual commands. Essentially, due to the way data is stored on SSDs, it is impossible to access every memory cell during a software driven wipe; no matter how many passes are made. The possibility of significant fragments of residual data remaining is always greater than zero. However, if you entirely encrypt an SSD, BEFORE adding any confidential material, then secure destruction is assured by 'forgetting' the key. But encrypting an SSD after the material is put on it is not sufficient. -- *** e-Mail is NOT a SECURE channel *** Do NOT transmit sensitive data via e-Mail James B.

Re: [CentOS] C7 AD server

Il 07/02/2016 15:59, Miguel Medalha ha scritto: >>> How I can assing permission on this share? > > You can easily do it by following the instructions on the Samba Wiki: > > https://wiki.samba.org/index.php/User_Documentation > Hi Miguel, I've followed the wiki how to but, I want configure a share on same machine where is hosted DC and seems that this is not possible. I've configured AD DC on C7 using ServNet packages. Now after provisioning, I've tried to join a win7 host and all works. After this, I've tried to add a share on AD server for all client, but when I try to assign permission on dir, I can't because my local system can't see domain user. If I run wbinfo -u I can see user domain. If I run getent passwd, I can't see user domain, and so I can't give permission on share for this user but only using 777 on share directory (and this is not what I want). Now, If I put a new samba4 machine and configure it as domain member, and join the domain, I can assign on this machine permission for user as explained from samba wiki. But this is not my case. I need to configure DC and share on same machine, but I can't figure out why I can't see domain user in my local system. Where is the problem? Thanks in advance
