Experiment with uselessd as a systemd replacement on openSUSE 13.1

an invention by dsterba

The base version for uselessd is systemd-208, which is the version used in 13.1. Let's try if a direct substitution of the binaries works and watch out for the problems.

sysvinit-base

a project by wiederda

Package a basic, stripped down version of sysvinit for emergency cases, so you can repair a failed system without interference. My goal is not to replace systemd with sysvinit again, but to provide a sysvinit-base package that does not have any dependencies at all and can just be installed on any system. sysvinit will only be used in exception situations by specifying the kernel parameter "init=/sbin/init" or something like that. The package will come with the binary, a minimal inittab and a basic boot script that does only the really needed stuff.

Kernel oops decoder

a project by benjamin_poirier

Read in a crash or oops-style backtrace and access DWARF information to output the current content of the stack and registers in term of symbols, and the the crash commands to dump/pretty print them. In other words, when looking at a crash dump, answer the questions "Which variable is currently stored in $rax? What is the structure of the stack? Which variable is stored at $rsp+16?"

Integrate e1000e into the Linux Kernel Backports project

a project by benjamin_poirier

The current approach to having new hardware support and features in SLE kernels it to integrate changes to individual drivers from the mainline kernel back into the SLE kernel. The Linux Kernel Backports project (https://backports.wiki.kernel.org/) in comparison has an approach which consists in adding a shim layer between unmodified mainline drivers and older kernel interfaces. This project has its roots in wireless drivers. It currently supports only a handful of old ethernet adapters.

gdb - better disassembly

The binding with source code lines is weird (even crash, which does use gdb beneath, does that better), I don't see the jump targets; furthermore, there's a lot more informations hidden in the DWARF2 which may be of some interest - like which code is inlined, or which register/stack address should contain some variable.

One way to see them is reading them from a kernel crashump.

Git stochastic bisection

a project by jankara

Bisection is a well known method of localizing which commit caused a regression in a code repository. git-bisect is a particularly used tool for this problem in git repositories. However it is often the case that the failure is probabilistic in nature - either because we don't have a reliable reproducer of the failure and thus not reproducing a problem on a particular commit does not mean the problem is not still present there, or because of inherent variability of e.g. performance regressions. Bisection for such failures is problematic as it takes only one false result for the bisection to end up in an unrelated part of code history. So in these cases we usually have to heavily extend runtime of a reproducer or do multiple test runs or multiple bisection runs to minimize a chance of error.
