[arch-general] most efficient way to get linux kernel statistics
by Andre Schmidt 08 Mar '16

08 Mar '16

hello archers, thought i ask here first, before i try some kernel mailing list. i'm writing (for fun) a tiny daemon that sends linux usage (cpu, mem, net, etc.) statistics as efficiently as possible to another machine, repeatedly, to get "live" data. at the moment i'm simply sending /proc files, but they sometimes have too much data. so was wondering if there is a more efficient way to get (only parts of) the data thats available in /proc? for example, /proc/meminfo has all this info: MemTotal: 8051660 kB MemFree: 6046020 kB MemAvailable: 6843080 kB Buffers: 109116 kB Cached: 708336 kB SwapCached: 0 kB Active: 1332416 kB Inactive: 455428 kB Active(anon): 971040 kB Inactive(anon): 22340 kB Active(file): 361376 kB Inactive(file): 433088 kB Unevictable: 16 kB Mlocked: 16 kB SwapTotal: 1048572 kB SwapFree: 1048572 kB Dirty: 16 kB Writeback: 0 kB AnonPages: 970412 kB Mapped: 323384 kB Shmem: 23008 kB Slab: 71760 kB SReclaimable: 44860 kB SUnreclaim: 26900 kB KernelStack: 6544 kB PageTables: 22924 kB NFS_Unstable: 0 kB Bounce: 0 kB WritebackTmp: 0 kB CommitLimit: 5074400 kB Committed_AS: 3487604 kB VmallocTotal: 34359738367 kB VmallocUsed: 0 kB VmallocChunk: 0 kB HardwareCorrupted: 0 kB AnonHugePages: 413696 kB HugePages_Total: 0 HugePages_Free: 0 HugePages_Rsvd: 0 HugePages_Surp: 0 Hugepagesize: 2048 kB DirectMap4k: 168600 kB DirectMap2M: 8091648 kB but i only need: MemTotal: 8051660 kB MemAvailable: 6843080 kB Cached: 708336 kB event better would be if kernel would only tell me: 8051660 6843080 708336 if /proc is the only way to get this info, i wonder if creating a kernel module for this would be more efficient, or even possible?

Re: [arch-general] Missing Dependency virtualbox-host-dkms

Would it be possible to depend on a "Provides" that all the different kernel header packages share? Similar to how nvidia-libgl, catalyst-libgl, and mesa-libgl all provide the "libgl" dependency. That would solve the presumably-very-common case where users initially installed virtualbox without any host headers at all, and are now landing in a broken state by default. (Or would that mean that the different header packages conflict where they didn't before?) - Jack

If I use the browser's find option to search "remove", I don't find information about removing old modules using 'dkms remove' here: https://wiki.archlinux.org/index.php/VirtualBox I'm aware the 'rm -r' and 'unlink' could be used either, it's just a surprise that 'dkms remove' doesn't work. Perhaps I'm mistaken and I used 'dkms remove' in the past before I upgraded. Regards, Ralf

[arch-general] JasPer vulnerabilities
by Harrison Wells 07 Mar '16

07 Mar '16

Is the package JasPer in extra repo vulnerable to CVE-2016-1577, CVE-2016-2089 and CVE-2016-2116? I noticed that the version number of JasPer is same in Debian, Ubuntu and Arch, i.e. 1.900.1. Debian and Ubuntu seem to have updated/patched it, is Arch not vulnerable to it? With regards, Harrison Wells

[arch-general] Missing Dependency virtualbox-host-dkms
by Chr1s 06 Mar '16

06 Mar '16

Cheers Replacing the `virtualbox-host-modules' with the `virtualbox-host-dkms' package causes a "modprobe: FATAL: Module vboxdrv not found in directory /lib/modules/4.4.3-1-ARCH". The whole misc (/lib/modules/4.4.3-1-ARCH/kernel/misc/) directory is missing. You need to install the `linux-headers' package for a working dkms. DKMS than can make the modules and creates the misc folder with all virtualbox *ko files. Is it possible to add the `linux-headers' package as a dependency for the `virtualbox-host-dkms' package or miss I something? Thanks Kind regards Chris

[arch-general] Wifi disconnects every few minutes
by Fulcrum 06 Mar '16

06 Mar '16

Hi everybody, I have an Alfa AWUS036H USB Wifi adapter (Ralink Technology, Corp. RT2870/RT3070 Wireless Adapter). It's using rt2800usb driver. I use netctl to connect to wifi.Here is my netctl profile: Description='Mine' Interface=wlp0s18f2u4 Connection=wireless Security=none ESSID=ncepu-student IP=static Address='10.110.7.7/24' Gateway='10.110.7.254' DNS=("8.8.8.8";"8.8.4.4") The problem is that 'ip addr show' says that I'm still connected to my wifi AP. I can see my IP and everything but I can't access internet. I can't even ping google or any other server. When I try to curl a local LAN web server, it says 'there is no route to xxx.xxx.xxx.xxx', where xxx.xxx.xxx.xxx is my local router. So I have to disconnect and reconnect every few minutes to use internet. Here are ping results to a local server (while still connected to wifi, as per 'ip addr'): PING yyy.yyy.yyy.yyy (yyy.yyy.yyy.yyy) 56(84) bytes of data. From 10.110.7.7 icmp_seq=1 Destination Host Unreachable From 10.110.7.7 icmp_seq=2 Destination Host Unreachable From 10.110.7.7 icmp_seq=3 Destination Host Unreachable From 10.110.7.7 icmp_seq=4 Destination Host Unreachable From 10.110.7.7 icmp_seq=5 Destination Host Unreachable From 10.110.7.7 icmp_seq=6 Destination Host Unreachable ^C --- yyy,yyy.yyy.yyy ping statistics --- 6 packets transmitted, 0 received, +6 errors, 100% packet loss, time 5008ms Where yyy.yyy.yyy.yyy is a server that is always available to all PCs connected to local LAN or wifi. I read somewhere that netctl and dhcp don't work well together so I changed DHCP to static IP*. I even tried changing the wifi access points (There are multiple APs around me). In all cases, I am able to connect to the AP and use internet, but only for a few minutes. For debugging, I removed the usb cable, and reattached the wifi adapter.Here are some entries from dmesg showing the plugging in of the adapter and subsequent connection trials. Note that I disconnected and reconnected the AP around [21713.142829].

[arch-general] libvirt and VirtualBox

Hello On an up-to-date Arch x86-64 system, I fail to manage VirtualBox VMs with libvirt virsh: $ virsh -c vbox:///session error: failed to connect to the hypervisor error: internal error: unable to initialize VirtualBox driver API Is this supposed to work out of the box? Both VirtualBox (5.0.14-1) and libvirt (1.3.2-1) are installed from the community repository, and VirtualBox support seems to be compiled in: $ virsh -V Virsh command line tool of libvirt 1.3.2 [...] Compiled with support for: Hypervisors: QEMU/KVM LXC UML OpenVZ VMware PHYP VirtualBox ESX Test [...] Furthermore, both VirtualBox alone (i.e. when managed by VBoxManage or similar) and libvirt when used to manage QEMU/KVM sessions work fine. Any hints about what I'm missing? TIA & cheers, Jukka -- This email fills a much-needed gap in the archives.

[arch-general] Heads up: If you are using SSLv2 turn it off immediately
by P. A. López-Valencia 03 Mar '16

03 Mar '16

If you are have a web server facing the public internet, turn off SSLv2 immediately. OpenSSL 1.0.2g has the fix but it will take a while to drip down to the repos as it brings with it an ABI change. The vulnerability is so bad[1], it doesn't only have a CVE number, CVE-2016-0800[4], but a name and its own website: HTTPS DROWN[1][2][3]. One third of all public web servers are open to attack[2][3] and OpenSSL may not be the only crypto library affected[1][4].
