[arch-general] Arch branded ODP slide for presentation
by Steve Ovens 22 Aug '18

22 Aug '18

Good day mailing list, I am giving an all day work shop at Ohio Linux Fest ( https://ohiolinux.org/olfi-training-2018/automation-with-bash-shell/). I want to give a vendor agnostic presentation and am hunting around for some decent Arch branded ODP template slides to include. My question is: 1) Is there someone I need to seek permission from to use Arch branding? 2) Does anyone have any good slide templates they can share? I appreciate your time. Regards -- Steve Ovens Consultant, RHCA DevOps Red Hat Canada Cell: 519-709-5775

[arch-general] Changes to jack/jack2 and realtime privileges
by David Runge 21 Aug '18

21 Aug '18

Hi all, as announced before [1], recent changes to the jack and jack2{,-dbus} packages (now in [extra] and [community] respectively) have made the previously shipped configurations obsolete and decoupled the audio group from acquiring realtime privileges by default when installing jack. The package realtime-privileges [2] has been created to serve as the new way of achieving this by the means of a dedicated 'realtime' group, to which users, that need the settings, must be added. It is now an optional dependency to jack and jack2{,-dbus} and can of course also be dependend upon from other packages if needed. In theory, this change shouldn't mean much of a difference to users, that need realtime (just install realtime-priviliges and add your user to the realtime group: `gpasswd -a <user> realtime`), while it doesn't have any consequences for users that have no use for it to begin with. Best, David [1] https://lists.archlinux.org/pipermail/arch-proaudio/2018-July/000163.html [2] https://www.archlinux.org/packages/community/any/realtime-privileges/ -- https://sleepmap.de

[arch-general] blueman authentication problem

Good evening, for approx the last 2 days I noticed that the blueman applet and rfkill state request me to enter my password when logging in Gnome Shell.

[arch-general] How to upgrade a postgresql database?
by Peter Nabbefeld 17 Aug '18

17 Aug '18

Hello, I'm trying to upgrade a postgresql database, but it doesn't work. I've also found this: https://wiki.archlinux.org/index.php/PostgreSQL#Upgrading_PostgreSQL This doesn't work for me, because there isn't any folder /opt/pgsql-9.6/bin anymore - all the binaries are in /usr/bin. This implies, there're no two versions of the binaries available, nor any oldir or newdir (for -b / -B parameters). It seems, I have to downgrade postgresql first, dump the database, and restore it after upgrading again. Is there any easier method available (i.e. some script which could do this automatically)? Kind regards Peter

[arch-general] i3stats depends on wireless_tools, causing "firmware load for regulatory.db failed" w/o wireless-regdb
by David C. Rankin 16 Aug '18

16 Aug '18

Archdevs, There seems to be a funny depends (or missing depends) issue for *some* systems without wireless that have i3status installed. This appears to be because i3stats depends on wireless_tools, which during boot triggers an attempt to load /var/lib/regulatory.db -- which fails because the file doesn't exist with the following: [ 11.924427] cfg80211: Loading compiled-in X.509 certificates for regulatory database [ 11.928144] cfg80211: Loaded X.509 cert 'sforshee: 00b28ddf47aef9cea7' [ 11.928215] platform regulatory.0: Direct firmware load for regulatory.db failed with error -2 [ 11.928219] cfg80211: failed to load regulatory.db This issue was touched on from a different angle in: https://bbs.archlinux.org/viewtopic.php?id=234568 The /var/lib/regulatory.db file is provided by wireless-regdb (a dependency of crda), but neither are a dependency wireless_tools. I don't know exactly what hardware triggers the attempt to load on systems without wireless. I have 2 SuperMicro boards that do throw the error, but similar setups on MSI and Gigabyte that don't. The error appears harmless, so I don't know if it is something that should even be addressed, but I thought I'd pass it along and let you devs make the call. -- David C. Rankin, J.D.,P.E.

[arch-general] Booting EFISTUB Kernel: Tianocore Wants *.efi.
by Ralph Corderoy 12 Aug '18

12 Aug '18

Hi, I've an Asus C200M Chromebook with coreboot and TianoCore UEFI newly flashed. Today was spent working through the wiki to have it EFISTUB boot a kernel in ESP. The disk has a ESP partition, and a root partition that's LUKS dmcrypt'd. (All this is new to me.) I used efibootmgr(8) to add a boot menu item, and I changed the order so it was second after USB. https://wiki.archlinux.org/index.php/EFISTUB#Using_UEFI_directly On finishing the installation and rebooting, I ended up EFI shell without any visible errors. Poking about, I could see ESP had `\vmlinuz-linux', in EFI terms, and the two initrds. Explicitly running the kernel, e.g. `fs0:\vmlinuz-linux' either did nothing, or said it wasn't the right kind of thing. I forget. On a hunch I used EFI's `cp' to copy it to `\vmlinuz-linux.efi'. `ls' then shows it in a different colour to its source and it booted with `\vmlinuz-linux.efi'. Where along the line do I arrange for the kernel to end with `.efi'? -- Cheers, Ralph. https://plus.google.com/+RalphCorderoy

[arch-general] valgrind error -- the 'impossible' happened?? (fully updated Arch system)

After update to current (as of now linux 4.17.14, and I just tested with 4.17.13 and the error is there too), valgrind fails with an 'impossible' error: ===== error start $ valgrind ./bin/opendir_readdir_dyn_char_basic ==1196== Memcheck, a memory error detector ==1196== Copyright (C) 2002-2017, and GNU GPL'd, by Julian Seward et al. ==1196== Using Valgrind-3.13.0 and LibVEX; rerun with -h for copyright info ==1196== Command: ./bin/opendir_readdir_dyn_char_basic ==1196== valgrind: the 'impossible' happened: Unsupported arch_prctl option host stacktrace: ==1196== at 0x580441BA: show_sched_status_wrk (m_libcassert.c:355) ==1196== by 0x580442D4: report_and_quit (m_libcassert.c:426) ==1196== by 0x58044517: panic (m_libcassert.c:502) ==1196== by 0x58044517: vgPlain_core_panic_at (m_libcassert.c:507) ==1196== by 0x5804454A: vgPlain_core_panic (m_libcassert.c:512) ==1196== by 0x580DAE22: vgSysWrap_amd64_linux_sys_arch_prctl_before (syswrap-amd64-linux.c:286) ==1196== by 0x580A0C23: vgPlain_client_syscall (syswrap-main.c:1857) ==1196== by 0x5809D48A: handle_syscall (scheduler.c:1126) ==1196== by 0x5809EBB6: vgPlain_scheduler (scheduler.c:1443) ==1196== by 0x580AED50: thread_wrapper (syswrap-linux.c:103) ==1196== by 0x580AED50: run_a_thread_NORETURN (syswrap-linux.c:156) sched status: running_tid=1 Thread 1: status = VgTs_Runnable (lwpid 1196) ==1196== at 0x401A1C5: ???

Thanks. ===== error end My question is does this look like an arch issue or is it just a kde upstream issue? I was answering a question on SO with a simple opendir/readdir of names into a dynamically allocated pointer-to-pointer-to-char and was showing how to test with valgrind. To my surprise valgrind croaked on Arch, but ran fine on SuSE and an old Arch box, so there is something wrong in the current valgrind on Arch. test source file at https://stackoverflow.com/questions/51804567/c-writing-readdir-to-char-arra… (it just reads the contents of the directory given as the first argument ('.' default) and qsorts and outputs the stored names before freeing the names and pointers. -- David C.
