F30 logwatch gets selinux error
by Robert Moskowitz 21 Aug '19

21 Aug '19

I get this error every few days. Is this some permission I have not set or a bug to report: SELinux is preventing mkdir from using the dac_override capability. ***** Plugin dac_override (91.4 confidence) suggests ********************** If you want to help identify if domain needs this access or you have a file with the wrong permissions on your system Then turn on full auditing to get path information about the offending file and generate the error again. Do Turn on full auditing # auditctl -w /etc/shadow -p w Try to recreate AVC. Then execute # ausearch -m avc -ts recent If you see PATH record check ownership/permissions on file, and fix it, otherwise report as a bugzilla. ***** Plugin catchall (9.59 confidence) suggests ************************** If you believe that mkdir should have the dac_override capability by default. Then you should report this as a bug. You can generate a local policy module to allow this access.

kswapd?
by Tom Horsley 21 Aug '19

21 Aug '19

I have vast amounts of free memory, yet I keep catching kswapd running at 100% every so often. Top also says I'm using a tiny bit of swap (for no reason I can fathom): MiB Mem : 15976.1 total, 979.6 free, 723.4 used, 14273.1 buff/cache MiB Swap: 32767.0 total, 32680.5 free, 86.5 used. 14920.2 avail Mem This is with kernel 5.2.8-200.fc30.x86_64 I never noticed this before. Anyone know what is going on?

List all packages which have a build requirement on package foo
by Stefan Schulze Frielinghaus 19 Aug '19

19 Aug '19

Hi all, How can I list all packages which have a *build* requirement on package foo? AFAIK build requirements are not stored as meta data in RPM files. Thus, repoquery won't help. The only option I am aware of would be to download all SPEC files and search for build requirements manually. Any other ideas? If not, is there a central repository of all SPEC files? The use case is that I would like to find out which package depends on package foo. The "normal" / runtime dependencies, i.e., Requires: foo can be queried via repoquery. However, it is unclear to me how to list packages which have a build requirement, i.e., BuildRequires: foo on package foo. Cheers, Stefan

Error starting domain: Requested operation is not valid: network 'default' is not active
by Patrick O'Callaghan 19 Aug '19

The above only happens when SElinux is Enabled. When Disabled, everything works. The same happens on both my VMs (Fedora and Windows). Looking at https://wiki.libvirt.org/page/Networking I tried: # virsh net-list --all Name State Autostart Persistent ---------------------------------------------- default inactive yes yes # virsh net-start default error: Failed to start network default error: internal error: Child process (VIR_BRIDGE_NAME=virbr0 /usr/sbin/dnsmasq --conf-file=/var/lib/libvirt/dnsmasq/default.conf --leasefile-ro --dhcp-script=/usr/libexec/libvirt_leaseshelper) unexpected exit status 11: dnsmasq: lease-init script returned exit code 1 I run my own dnsmasq (and QEMU/KVM runs its own dnsmasq separately) but this has not been an issue recently. # cat /var/lib/libvirt/dnsmasq/default.conf ##WARNING: THIS IS AN AUTO-GENERATED FILE.

Question on missing file from syslinux rpm?
by Michael D. Setzer II 19 Aug '19

19 Aug '19

I use syslinux in the g4l project I've maintained since 2004, and noticed that Fedora 30 includes the later 6.04 version versus the latest full released 6.03 version. Did a test, and noted that all the files except display.c32 are included with the fedora 30? Note sure if it was left out for a reason, or by accident? Sent emails to the two email address that were in the info I found on the rpm at fedora project, but haven't gotten an answer from either yet? Doesn't greatly effect project, since booting works, but if user wants to drop to boot prompt, it was the only option to be able to examine text files.

about dnf install with multi arch
by Changqing Li 18 Aug '19

18 Aug '19

Hi, Hopefully this is the right place to ask this, if not, please kind to tell me. I want to know does archs in /etc/dnf/vars/arch have same priority? Here is problem I met: under the repo, there are packageA.arch1.rpm which provide C and others, also have packageB.arch2.rpm also provide C 1. if etc/dnf/vars/arch configed as arch1:arch2:arch3:arch4 dnf install packageA packageB will success, seems arch1 is high priority than arch2, so packageA is installed, packageB is skipped 2. if etc/dnf/vars/arch configed as arch2:arch3:arch1:arch4 dnf install packageA packageB will fail with below error: packageA.arch1 conflicts with C provided by packageB.arch2 conflict request I am confused, if the first arch with highest priority, why in condition 2 conflict request is reported? Not package B is installed and PackageB is skipped? Is it related with the content of package A/B? Can anyone explain how the conflict is detected? Thanks in advance. -- BRs Sandy(Li Changqing)

Loopback mount in fstab fails
by Patrick O'Callaghan 17 Aug '19

17 Aug '19

I'm trying to rationalise space by moving my /var directory from its own partition to /, as currently there's a lot of wastage. I've copied /var to /newvar with rsync, and now want to mount /newvar as /var on reboot by creating an entry in /etc/fstab. This is it (using /var-tst for testing): /newvar /var-tst ext4 loop 0 0 but I'm getting: mount: /var-tst: failed to setup loop device for /newvar. /var-tst exists, so that's the problem? The man page for mount states that it will create the necessary /dev loopback device if it isn't specified. Currently there are no loopback devices in the system, and the loop kernel module is loaded. poc PS Suggestions on how to move /var without all this jiggery-pokery are also welcome.

F30 not using extra battery on Lenovo T470s
by Chris Bredesen 17 Aug '19

17 Aug '19

I'm seeing some new behavior recently where my laptop shuts down hard, with no warning, at about 50% battery. After the third time it happened I took a look at the battery levels (after plugging in and restarting) and found that the main battery was at 1% and charging, while the extra battery was at 100% and fully charged. So it would seem that my system is ignoring the extra battery or somehow not tapping into it at runtime. I don't recall this ever happening in the past and I'm not sure if this is an OS issue or something lower level. Anyone seen or know how to diagnose this? Thanks! -CB

amd card resets itself
by Łukasz Posadowski 17 Aug '19

17 Aug '19

Hello everyone. Recently I bought and AMD Radeon 570 card and was eager to test built in Linux drivers on Fedora 30. While they work, card is behaving really strange. As soon as it hits around 100% GPU usage, even for a brief moment (which is exactly the moment gdm starts), it resets itself and display artifacts on the screen. System works and I can ssh into it without any problem, or switch into local text console. The only way to keep it from those resets is echo 'low' > /sys/class/drm/card0/device/power_dpm_force_performance_level in text mode before isolate graphical target. Default value is "auto". It's not preventing the crashes, they happens from time to time, but the screen goes black immediately, so I thinks it's unrelated problem. The card is not overheating, it's max around 50 degrees Celsius and both fans are spinning fine. Anyone of You have heard of resetting AMD cards? They could be easily identified by the line in journald: amdgpu 0000:01:00.0: GPU reset begin! but the reset is never completed successfully. It can be easily misinterpreted as hard system crash, because nothing happens on the display, but it's not. Only something related to the GPU in broken. I asked AMD support, but they suggested checking it on Windows 10, which I don't have. I really want to debug this for Linux, but I don't know where to look. If You have Radeon 570, or know someone who has it, please let me know if You have, or have not any problems. As far as I know for now, my card may be physically broken. thanks in advance -- Łukasz Posadowski

Volume/mute/brightness keys stopped working
by Ian Pilcher 17 Aug '19

17 Aug '19

I have a Dell Precision 5520 laptop (basically an XPS 15). The volume, mute, and brightness "function" keys have always just worked on this laptop with no additional configuration required ... until now. Something has changed in the last week or two, and the keys no longer have any effect (except that the brightness increase key now toggles the maximized state of terminal windows). Anyone else seen this recently? Assuming no, anyone have any hints on how to debug this? I'm not really sure how these function keys work (i.e. are they keypresses, ACPI events, something else?). Any thoughts appreciated. Thanks! -- ======================================================================== Ian Pilcher arequipeno(a)gmail.com -------- "I grew up before Mark Zuckerberg invented friendship" -------- ========================================================================
