I am not sure I understand this. If someone has the default mkinitcpio.conf it won't boot? In my case I set it to lz4 over a year ago for speed.

[arch-general] About package guidelines
by Óscar García Amor 21 Feb '21

21 Feb '21

Hi, When a user submit a package to AUR must follow package guidelines. There is an interesting point that says that in the top of PKGBUILD you must respect the previous contributors [1] and credit them (if any). I'm surprised that this is not respected by the trusted users when they pick an arbitrary package that is maintained in AUR and upload it to the community repository without crediting anyone of past maintainers. I saw this course of acting in several packages and don't like to me. It seems to me a total lack of respect towards the person or people who have been keeping the package so far. If users of the AUR are required to have a minimum of netiquette, more should be required of TUs. Greetings.

[arch-general] fail2ban archlinux
by Maykel Franco 18 Feb '21

18 Feb '21

Hi, I've configured fail2ban with action, filter for my php application. My app output log like this: unknown user foo (192.x.x.x) My jail conf: [php-app-login] enabled = true port = 80 protocol = tcp filter = php-app-login logpath = /var/www/php-app-login/var/logs/dev.log findtime = 3600 bantime = 86400 maxretry = 3 ignoreip = 127.0.0.1/8 My filter definition: [Definition] failregex = unknown user .* $<HOST>$ ignoreregex = It works well, but I like fail2ban add comment in iptables rule when add ban IP. For example: iptables -A INPUT -p tcp --dport 80 -m comment --comment "Ban foo" -j DROP iptables -L -n -v Chain INPUT (policy ACCEPT 94 packets, 23457 bytes) pkts bytes target prot opt in out source destination 0 0 DROP tcp -- * * 0.0.0.0/0 0.0.0.0/0 tcp dpt:80 /* Ban foo */ I've googled and I think something needs to be changed in action but I can't find how to pass the user variable to that action.

[arch-general] [RFC] Potentially deprecating primus, bumblebee, virtualGL and primus_vk
by Emil Velikov 16 Feb '21

16 Feb '21

Hello all, As some of you may know, I have been an Arch user for over 5 years and a Linux graphics developer working on the whole stack from the kernel DRM all the way up-to Mesa and X. I would like to propose, partially deprecating and potentially removing some of the said packages in light of the development that has been happening over the last few years. tl;dr: these solutions have been partially or completely obsolete, for a while now ## OpenGL/GLX/etc # Background As you know, in the early days we would have both Mesa and vendors provide their own libGL.so.1 and in some cases libglx.so (xorg module). Alongside that drivers lacked dynPM, allowing you to powering off the GPU, when it's not used. To address those primus and bumblebee came about. Note: dynPM is mentioned for completeness, it won't be covered any more. # Since then Nvidia and open source drivers support client - Mesa drivers - since v17.2.0 (at least), packaged 7 Sep 2017 - Nvidia drivers - since v390.25 (at least), packaged 29 Jan 2018 ... and server-side glvnd: - xorg-xserver - since v1.20.6, packaged 23 Nov 2019 - Nvidia drivers - since v435.21, packaged 30 Aug 2019 ## Vulkan # Background On the Vulkan side the drivers are clearly separated from the start - libvulkan_$vendor.so. Yet very few applications would bother selecting the GPU, plus server-side (when using WSI_X11) wasn't complete. GL Vulkan interop was also tricky, with libGL.so.1 being provided by vendors. This resulted in primus_vk. # Since then - Mesa drivers - since 20.1.0, packaged 28 May 2020 Driver selection layer was added, falling back to DRI_PRIME [1] - Nvidia drivers - since v390.25 (at least), packaged 29 Jan 2018 Vulkan implicit layer was added - see [2] ## My proposal: Cleanup the packages, as outlined below and update the wiki. Please check out the Extra notes below. I will be more than happy to tackle this although maintainers will have to push/rebuild the packages for obvious reasons. - primus: replace with a simple compat script primusrun, which a) finds the ID_PATH_TAG for the Nvidia GPU and sets DRI_PRIME=$tag $@ - bumblebee: optirun - replace with script calling primusrun xorg config - should not be needed, double-check and drop bumblebeed - (optionally) remove no longer applicable code, config etc bumblebee - remove no longer applicable group - virtual GL: move to AUR, since it has no more users - primus_vk: replace with a simple compat script pvkrun akin to primusrun, making use of [1] and [2] ## Extra notes: - primus/bumblebee - seemingly been abandoned upstream for 4+ years. Arch maintainers having to carry fixes locally. - primus/virtualgl/primus_vk performance is worse than natively - compat primusrun/optirun/pvkrun are to minimise breakage - some legacy Nvidia drivers may lack support - those drivers live in the AUR, thus a solution for them should also be packaged there. ## Feedback I would love to hear the input from the respective maintainers and the overall Arch developer base as a whole. Is there a particular use-case that I've missed? How would you like this handled - as mentioned above, I'm happy to submit patches be that via Flyspray, email, MR or otherwise. Looking forward to your input -Emil [1] https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/1766 [2] http://download.nvidia.com/XFree86/Linux-x86_64/435.17/README/primerenderof…

[arch-general] Mounted ext4 filesystem without journal
by Alexander Kapshuk 08 Feb '21

08 Feb '21

Most probably due to a buggy custom kernel, fsck on /dev/sda2, i.e the root partition, failed with a rootfs prompt and an invitation to run fsck on /dev/sda2 presented. On having done that and rebooted, when performing fsck on /dev/sda2, the system reported that: /dev/sda2 had not been cleanly unmounted 0.4% non-contiguous blocks mounting /dev/sda2 on real root EXT4-fs (sda2) mounted filesystem without journal Root device mounted successfully, but /sbin/init does not exist. The wiki article on fsck troubleshooting, https://wiki.archlinux.org/index.php/Fsck#Troubleshooting, suggests using tune2fs to write a new journal to /dev/sda2. But it doesn't seem to be available when in rootfs. Booting into the Arch Linux installation CD and mounting /dev/sda2 over /mnt reveals lost+found as the sole contents of the directory. As an experiment, mounting /dev/sda1 over /mnt confirms the presence of all the files there are on my boot partition. Any pointers on how to proceed with this would be much appreciated.

[arch-general] Arch Linux OVH end of support

Hi, Seems that Arch Linux will be unsupported in OVH [1] maybe a big warning should be added on the wiki [2], especially considering that the contract with OVH is usually signed for one year.

[arch-general] Change how cross compilers are packaged
by Christer Solskogen 08 Feb '21

08 Feb '21

I've been using the aarch64 cross compiler packages for some time, lately I've also taken a look at how that PKGBUILD looks and how it relates to Cross-compiling tools package guidelines. The situation now is that aarch64-linux-gnu-glibc installs into a sysroot in /usr/aarch64-linux-gnu. Where also aarch64-linux-gnu-binutils installs some files into. This is bad because the sysroot is a directory thats supposed to be reserved for the target system. This is fine on bare-metal systems, but not for linux/mingw targets. What do you think of having /usr/sysroot/$target as sysroots instead for targets that are supposed to be configured that way? Only a small hand full of packages needs to be rewritten (aarch64, mingw-w64 and riscv64) - and I can fix that I (the package maintainers still need to review my changes, as I don't have git access) One other option would be to follow gcc's defaults, which is $prefix/$target/sys-root But before I do that, I'd like some comments if you think this is needed. I don't want to waste time :-) At the same time, I would remove some of the old/deprecated options for binutils, glibc and gcc that are present in the current PKGBUILDs. -- chs
