C7 and mdadm
by mark 23 Jan '19

23 Jan '19

A user's system had a hard drive failure over the weekend. Linux RAID 6. I identified the drive, brought the system down (8 drives, and I didn't know the s/n of the bad one. why it was there in the box, rather than where I started looking...) Brought it up, RAID not working. I finally found that I had to do an mdadm --stop /dev/md0, then I could do an assemble, then I could add the new drive. But: it's now cat /proc/mdstat Personalities : [raid6] [raid5] [raid4] md0 : active (auto-read-only) raid5 sdg1[8](S) sdh1[7] sdf1[4] sde1[3] sdd1[2] sdc1[1] 23441313792 blocks super 1.2 level 5, 512k chunk, algorithm 2 [7/5] [_UUUU_U] bitmap: 0/30 pages [0KB], 65536KB chunk unused devices: <none> and I can't mount it (it's xfs, btw). *Should* I make it readwrite, or is there something else I should do? mark

Yum refuses to install kmod-8188eu from elrepo
by Marko Vojinovic 23 Jan '19

23 Jan '19

I am having trouble using the realtek wifi chip in my new tp-link usb wifi dongle. Upon plugging it, the device gets registered by the kernel (in /var/log/messages), but that's about it, no network device is being created (iwconfig does not see it, nothing else works). A few google searches later I found out that this realtek chip is not supported by the kernel and requires a driver, and that the driver is packaged for C7 as kmod-8188eu in elrepo. However, yum install kmod-8188eu refuses to install it (full yum output is here: https://pastebin.com/raw/vvak6FCU ), complaining that the following dependencies cannot be met: --> Processing Dependency: kernel(wireless_send_event) = 0xa02e7e03 for package: kmod-8188eu-4.1.4_6773.20130222-4.el7_5.elrepo.x86_64 --> Processing Dependency: kernel(usb_submit_urb) = 0x74c6ac58 for package: kmod-8188eu-4.1.4_6773.20130222-4.el7_5.elrepo.x86_64 --> Processing Dependency: kernel(usb_reset_device) = 0xddd0084e for package: kmod-8188eu-4.1.4_6773.20130222-4.el7_5.elrepo.x86_64 --> Processing Dependency: kernel(usb_put_dev) = 0xf709107c for package: kmod-8188eu-4.1.4_6773.20130222-4.el7_5.elrepo.x86_64 --> Processing Dependency: kernel(usb_kill_urb) = 0xa55bf715 for package: kmod-8188eu-4.1.4_6773.20130222-4.el7_5.elrepo.x86_64 --> Processing Dependency: kernel(usb_get_dev) = 0x372a41af for package: kmod-8188eu-4.1.4_6773.20130222-4.el7_5.elrepo.x86_64 --> Processing Dependency: kernel(usb_free_urb) = 0x739aecf4 for package: kmod-8188eu-4.1.4_6773.20130222-4.el7_5.elrepo.x86_64 --> Processing Dependency: kernel(usb_control_msg) = 0xd04e3a9e for package: kmod-8188eu-4.1.4_6773.20130222-4.el7_5.elrepo.x86_64 --> Processing Dependency: kernel(usb_alloc_urb) = 0x12a4948e for package: kmod-8188eu-4.1.4_6773.20130222-4.el7_5.elrepo.x86_64 I've never seen such output from yum before --- I'm guessing it is asking for a kernel with specific "properties", and failing to find one. What is the best way to resolve this? Is there some kernel package somewhere that matches these properties, or is there some other package that provides these features to an existing kernel, or something else? Or should I just ditch the kmod, and compile the 8188eu driver from source? I'd prefer to avoid this if possible, since I am not a fan of recompiling it every time the kernel is updated in C7. And I might need to use the wifi dongle on multiple machines, anyway. I'd appreciate any suggestions! TIA, :-) Marko

Dear team I am running a centos guest VM which freezes for every few days . The qemu-kvm on shows 100% cpu utilization. Ping to the guest might work or may not work .Please can you tell me what approach can i take to debug it . using "virsh dump" I can dump the core of the guest vm but I am not sure how to analyse it .

Does someone have a link to a how-to-do-it with firewalld, not "disable firewalld and use iptables"? mark

Re: [CentOS] SElinux AVC signull
by Sean 18 Jan '19

Hi Leon, I don't have access to a CentOS 6.10 system handy, but it looks like a policy issue. If I take you're ausearch output and pipe it to audit2allow on my CentOS 7.6 system, I get the following: #============= httpd_t ============== #!!!! This avc is allowed in the current policy allow httpd_t httpd_sys_script_t:process signull; Noting that on my 7.6 system with selinux enforcing with selinux policy packages at version 3.13.1-229, it notes that your denial would not happen. If you don't have it installed policycoreutils-python provides the audit2allow and audit2why binaries which can help you generate a policy to avoid this denial if you want. Also, I often find that to truly diagnose the issue, I need to run the following: # semodule --disable_dontaudit --build # setenforce permissive # tail -f /var/log/audit/audit.log | grep denied | tee ~/denials.out ... then reproduce the problem, and kill the tail. The resulting denials.out file will have a lot of unrelated denials, but if you run audit2allow against the entire file, you'll be able to determine which ones are not relevant by the comments produced (much like above where it told us the "avc is allowed"). You can also use this to generate a custom policy module for your system. Sometimes there are denials that are not audited which are relevant to the problem, which seems problematic to me...that there is a default set of things that get denied but do not appear in the audit logs. That's a different conversation though. Anyway, after the data is collected for the denials.out file you can reset to your normal operating stance... # semodule --build # setenforce enforcing From: Leon Fauster <leonfauster(a)googlemail.com> To: CentOS mailing list <centos(a)centos.org> Cc: Bcc: Date: Thu, 17 Jan 2019 18:35:23 +0100 Subject: [CentOS] SElinux AVC signull I have some perl scripts running via CGI to print some monitoring informations out. # cat /etc/redhat-release CentOS release 6.10 (Final) # getenforce Enforcing # LANG=C ausearch -m avc --start today type=SYSCALL msg=audit(1547733474.941:28): arch=c000003e syscall=62 success=no exit=-13 a0=641 a1=0 a2=7f33500079b0 a3=31372f656d6f7268 items=0 ppid=1399 pid=1439 auid=4294967295 uid=48 gid=48 euid=48 suid=48 fsuid=48 egid=48 sgid=48 fsgid=48 tty=(none) ses=4294967295 comm="httpd" exe="/opt/rh/httpd24/root/usr/sbin/httpd" subj=system_u:system_r:httpd_t:s0 key=(null) type=AVC msg=audit(1547733474.941:28): avc: denied { signull } for pid=1439 comm="httpd" scontext=system_u:system_r:httpd_t:s0 tcontext=system_u:system_r:httpd_sys_script_t:s0 tclass=process I see a lot of such entries but I don't see any service misbehaviour.

Hi, folks, Got a user that's recently(? been having odd things with her workstation video. This morning, in the logs, long before she got in, I saw a ton of errors Jan 18 08:06:50 <workstation> kernel: VM fault (0x04, vmid 1) at page 10, write from CP (48) Jan 18 08:06:50 <workstation> kernel: radeon 0000:01:00.0: GPU fault detected: 146 0x01433014 Jan 18 08:06:50 <workstation> kernel: radeon 0000:01:00.0: VM_CONTEXT1_PROTECTION_FAULT_ADDR 0x0000000A Jan 18 08:06:50 <workstation> kernel: radeon 0000:01:00.0: VM_CONTEXT1_PROTECTION_FAULT_STATUS 0x03030014 I see that radeon.ko is part of the kernel, and there's no updates. She running kernel 3.10.0-957.1.3.el7.x86_64. I see no errors in Xorg.0.log. Anyone got a clue, or see this error? mark

Inconsistent NIS Client Behavior w/ Centos 7.6
by Capehart, William J 16 Jan '19

16 Jan '19

Hi All. I am working on bringing back a number of Centos 7 rigs in our student computer lab back online. No change was made to the existing server machine [running Scientific Linux 6] Right now there is one remaining thing to resolve: an inconsistency with the rigs' NIS Clients. I have configured rcpbind and ypbind following guidance from Server World ( https://www.server-world.info/en/note?os=CentOS_7&p=nis&f=2 ) identically on all of the client machines. I have done this before with previous installs before this. The last time was this summer. Three are behaving as they are supposed to do. Five, however, are not. In this process I have repeatedly checked that support files .. /etc/sysconfig/network /etc/yp.conf /etc/pam.d/system-auth-ac /etc/pam.d/system-auth /etc/login.defs /etc/sysconfig/authconfig They are identical. IP addresses, Netmasks, Gateways, DNS, etc. are correct and all rigs (Server and Clients) do not conflict on any of the machines or /etc/host files. Disabling firewalls don’t impact the problem. NFS and other services work fine. All other aspects of networking is fine. You can ssh and access the Server rig from the Client rigs and for locally installed accounts on the clients go the other way. Accounts that leverage NIS cannot log into the Client from the Server or any other remote system. rpcbind shows that the ypbind/ypserv services are up and Clients and Server, respectfully (and it works on some of the machines). The rigs that are not working exhibit the following (satisfactory) behavior. * yptest -u [valid nis username] works with no errors. * yppasswd will change a password on the NIS server with no errors and other commands like ypchfn will work as well. * ypwhich, ypcat, ypmap, etc. give the same values we'd see on the NIS server. ...BUT... * You cannot console-login, ssh, or su into the rigs with valid NIS accounts. * (The local ypbind -d "debug mode" shows no response to a login, the "secure" log responds to a valid NIS account login with an "invalid user" a the [preauth] phase) * uids of valid NIS users are not recognized. * With ls -l, we see the uid of a file’s owner and not the username. (gids are explicitly declared locally on all rigs so they’ll match anyway.) * The id command for any valid nis user fails with "no such user" * cd ~[Valid NIS User] responds with "no such directory" even if the home directory exists (and the uid matches the uid on the NIS server). I am totally at a loss here. I cannot see the difference in what I did on the machines that work and the machines that do not work. Is there any test that I am missing or are there any files or setting where the culprit(s) on the errant machines may be? Cheers and Thanks --------------------------------------------------------------------------------------- Dr. Bill Capehart <William.Capehart(a)sdsmt.edu<mailto:William.Capehart@sdsmt.edu>> Director, Atmospheric and Environmental Sciences Program Department of Civil and Environmental Engineering 201 Mineral Industries Building (MWRF) 123 Civil Mechanical Building (T) South Dakota School of Mines and Technology 501 East St Joseph Street Rapid City, SD 57701-3995 USA Ph: +1-605-394-1994 Mobile: +1-605-484-5692
