Trace back related to nouveau with 6.8
by David G. Miller 05 Jun '16

05 Jun '16

Hi All - Ever since I upgraded to 6.8 I have usually been getting a trace back report for some bits related to Nouveau whenever the screensaver has been running and I get back into the system. Along the lines of: :Pid: 31, comm: events/4 Tainted: G W -- ------------ 2.6.32-642.el6.x86_64 #1 :Call Trace: :[<ffffffff8107c911>] ? warn_slowpath_common+0x91/0xe0 :[<ffffffff8107c97a>] ? warn_slowpath_null+0x1a/0x20 :[<ffffffffa00e35b6>] ? drm_helper_choose_crtc_dpms+0xa6/0xb0 [drm_kms_helper] :[<ffffffffa00e40d6>] ? drm_helper_connector_dpms+0xe6/0x1a0 [drm_kms_helper] :[<ffffffffa01e1e80>] ? nv50_crtc_dpms+0x0/0x10 [nouveau] :[<ffffffffa0134f01>] ? nvif_notify_init+0x121/0x160 [nouveau] :[<ffffffffa01dfe42>] ? nouveau_connector_hotplug+0x92/0xd0 [nouveau] :[<ffffffffa0134f40>] ? nvif_notify_work+0x0/0xc0 [nouveau] :[<ffffffffa0134f6e>] ? nvif_notify_work+0x2e/0xc0 [nouveau] :[<ffffffffa01ecf10>] ? nouveau_fence_work_handler+0x0/0x30 [nouveau] :[<ffffffff8109fdc0>] ? worker_thread+0x170/0x2a0 :[<ffffffff810a6ac0>] ? autoremove_wake_function+0x0/0x40 :[<ffffffff8109fc50>] ? worker_thread+0x0/0x2a0 :[<ffffffff810a662e>] ? kthread+0x9e/0xc0 :[<ffffffff8100c28a>] ? child_rip+0xa/0x20 :[<ffffffff810a6590>] ? kthread+0x0/0xc0 :[<ffffffff8100c280>] ? child_rip+0x0/0x20 PID 31 is: root 31 0.9 0.0 0 0 ? S Jun03 12:44 [events/4] It seems to be innocuous (everything seems to still work) but things that seem to be innocuous have a habit of coming back and biting me. Anyone else experiencing this? Anyone know how to fix it? Both kernel and xorg-x11-drv-nouveau are current as is the rest of the system. Not finding anything with Google. Cheers, Dave

by Alessandro Baggi 03 Jun '16

03 Jun '16

Hi list, I'm planning to buy a mobo (z170-K) that has Realtek 8111GR (nic). I've tried to search on google about support on C7 but can't fine anything. There is a way to check if supported? Is the Realtek 8111GR supported or I must change mobo? Thanks in advance.

I just had to browse to a printer... and with https-use-strict at a server higher up, firefox *would* *not* let me get there. I don't see the circa-2012 printer offering https. Luckily, there was konqueror, which *did* let me go to http://<printer> I just *adore* SmartSoftware that Won't Let You Endanger Yourself.... Reminds me of Jack Williamson's old novel, The Humanoids.

pam_sss fails to close cache files
by Anand Buddhdev 03 Jun '16

03 Jun '16

Dear folks, After updating some of our servers to CentOS 6.8, we've noticed that the ones using pam_sss.so for authentication, appear to be suffering from a leak of sorts. On these systems, the /var partition is running out of disk space, and we eventually noticed that it's because of deleted, but still open files like these: httpd 1081 apache 8r REG 253,2 6406312 6199 /var/lib/sss/mc/group (deleted) sshd 1609 root 3r REG 253,2 8406312 431 /var/lib/sss/mc/passwd (deleted) mysqld 2018 mysql 4r REG 253,2 10406312 436 /var/lib/sss/mc/initgroups (deleted) Each time any process uses pam in some way, it's opening these cache files in /var/lib/sss/mc, but not closing them, and they're accumulating. The reason they're accumulating is that the initgroups, group and password file are frequently refreshed (by sssd), and so each open() call to them looks at a new file. We traced the sshd process, and noticed this: open("/var/lib/sss/mc/passwd", O_RDONLY|O_CLOEXEC) = 3 But there is no matching "close(3)" call anywhere (all other files opened have a matching close() system call). Has anyone else seen this issue, and does anyone know a quick solution to this? Regards, Anand

Minimum RAM requirement for CentOS 6.x graphic installer?
by Nicolas Kovacs 02 Jun '16

02 Jun '16

Hi, The title says it all. What's the minimum RAM requirement for the CentOS 6.x graphic installer? In our public libraries we have some old hardware running CentOS 5, and I wonder if some of these machines can be upgraded to CentOS 6. Unfortunately RHEL 5.x' nifty text mode installer got seriously crippled with version 6.x.

Re: [CentOS] [exim] Exim not always logging Message-ID

Some of us, well at least 1, have written a simple PHP programme, run on Apache, which instantly searches the current log and the archived logs for anything in the logs. Tracing items in Exim could not be quicker or easier - all done from the comfort of a web page with no terminal CLI or GREP insight. -- Regards, Paul. England, EU.

Hi folks, I have a problem, shame on me I feel as newbie, I cannot open Firefox though ssh. ssh server is 7.2 and ssh client (running Xorg) is Fedora 23. Firefox does not open. I've tried a lot of methods, even adding xauth cookie, and for example: firefox --no-remote --no-xshm debug3: receive packet: type 90 debug1: client_input_channel_open: ctype x11 rchan 2 win 65536 max 16384 debug1: client_request_x11: request from 127.0.0.1 59181 debug2: fd 7 setting O_NONBLOCK debug3: fd 7 is O_NONBLOCK debug1: channel 1: new [x11] debug1: confirm x11 debug3: send packet: type 91 debug3: receive packet: type 90 debug1: client_input_channel_open: ctype x11 rchan 3 win 65536 max 16384 debug1: client_request_x11: request from 127.0.0.1 59183 debug2: fd 8 setting O_NONBLOCK debug3: fd 8 is O_NONBLOCK debug1: channel 2: new [x11] debug1: confirm x11 debug3: send packet: type 91 debug2: channel 2: rcvd adjust 39228 I need to open a browser, ok, I could install konqueror, but it pulls a bunch of apps that really I don't need. I'd want to install a browser from official repo... Could you help me? -- -- Sergio Belkin LPIC-2 Certified - http://www.lpi.org
