Feature added by: Adrian Schröter (adrianSuSE) Feature #317762, revision 1 Title: git mirror integration Buildservice: New Milestone: 2.7 Priority Requester: Mandatory Requested by: Adrian Schröter (adriansuse) Partner organization: openSUSE.org Description: OBS can already roll tar balls from git (or other SCM systems) on code change, however, this has two disadvantages: * source server needs to store new tar ball for each change * using files as build descriptions is only working via workarounds. A full git (and only git, not svn,..) support would allow to mirror an entire git tree on the source server and fetch only updates. This means we need to * build tar balls at build time (since package systems like rpm rely on it) * ensure that a rewritten git history can not drop sources of former builds. * allow mirroring of either * * package sources only * * entirely on package level, including .spec files -- openSUSE Feature: https://features.opensuse.org/317762

[New: openFATE 316517] 32bit version of padsp in 64bit openSUSE
by fate_noreply＠suse.de 27 Jun '16

27 Jun '16

Feature added by: Mircea Kitsune (MirceaKitsune) Feature #316517, revision 1 Title: 32bit version of padsp in 64bit openSUSE openSUSE Distribution: Unconfirmed Priority Requester: Desirable Requested by: Mircea Kitsune (mirceakitsune) Partner organization: openSUSE.org Description: I've been trying to fix a Linux game for which sound wasn't working. After some searching, I found that I must run it with the "padsp" command. However, the game is 32 bit and I run 64 bit openSUSE, so "padsp ./game_binary" wouldn't work. I searched for a padsp32 command and even tried to replicate the padsp script, but the library for the x32 version doesn't exist in the x64 repositories. Eventually I got it working by extracting libpulsedsp.so from the x32 openSUSE repos, and manually launching the binary with a LD_PRELOAD pointing to it. This is a workaround and maintaining it can become problematic. The existing library can be found in /usr/lib64/pulseaudio/libpulsedsp.so and the script in /usr/bin/padsp. Basically, I'm asking for x32 bit versions of these in the x64 variant of openSUSE, so any 32bit program can benefit from them too. Business case (Partner benefit): openSUSE.org: Only the 64bit version of padsp is included. Therefore, only 64bit programs can make use of it. Including the 32bit variant in the 32bit pulseaudio package for 64bit openSUSE would solve this problem. -- openSUSE Feature: https://features.opensuse.org/316517

[New: openFATE 315140] Kernel: CONFIG_TCP_MD5SIG needed for quagga
by fate_noreply＠suse.de 15 Jun '16

15 Jun '16

Feature added by: Marc Langer (marclanger) Feature #315140, revision 1 Title: Kernel: CONFIG_TCP_MD5SIG needed for quagga openSUSE Distribution: Unconfirmed Priority Requester: Important Requested by: Marc Langer (marclanger) Partner organization: openSUSE.org Description: Quagga bgpd allows the configuration of MD5 protected BGP sessions, but the kernel does not have this activated. Business case (Partner benefit): openSUSE.org: Our BGP peers require MD5 but the SuSE Kernel is compiled without CONFIG_TCP_MD5SIG. It takes a long time to find this issue because in the default configuration quagga is not logging properly that this option is missing in the kernel. Each time we have to compile an own kernel. Please activate this in future versions. -- openSUSE Feature: https://features.opensuse.org/315140

[New: openFATE 320894] osc should download files from linked repositories only once
by fate_noreply＠suse.de 21 May '16

21 May '16

Feature added by: Stefan Brüns (StefanBruens) Feature #320894, revision 1 Title: osc should download files from linked repositories only once Buildservice: Unconfirmed Priority Requester: Desirable Requested by: Stefan Brüns (stefanbruens) Partner organization: openSUSE.org Description: Typically all or most files in linked repositories are identical. By default osc downloads linked repositories in expanded state, downloading the same files again and again. The project meta data already contains the md5sums and file sizes of the source files. Business case (Partner benefit): openSUSE.org: Duplicate downloads waste bandwidth on the build service and developer time on checkouts. -- openSUSE Feature: https://features.opensuse.org/320894

[openFATE 320868] gcc multiverse support
by fate_noreply＠suse.de 13 May '16

13 May '16

Feature changed by: Michael Matz (matz2) Feature #320868, revision 2 Title: gcc multiverse support Requested by: Luis Rodriguez (mcgrof) + Partner organization: openSUSE.org Description: One of the task involved in FATE#315712 ("XEN: Use the PVOPS kernel") was to develop a solution to address dead-code concerns. This is being developed through a linker-table solution documented as part of a generic kernel-sandboxing strategy (http://kernelnewbies.org/KernelProjects/kernel-sandboxing) . This work is ongoing, and has broad uses outside of the scope of the Linux kernel. Long term, the Linux kernel solution may end up re-using some of the existing infrastructure to free __init code to free code when needed, and may extend this functionality to also alternatively do other things with region of unused code, one option for instance may be to make certain code not present to trigger page faults upon access. These solutions are very Linux specific and generalizing this may prove hard in other projects of interest to SUSE. In review with Alexander Graf, he has proposed an alternative mechanism which would be much more appropriate as a generic solution, this requires extending gcc. Support for this feature and public traction of this feature is being documented on the kernel newbies compiler-multiverse wiki (http://kernelnewbies.org/KernelProjects/compiler-multiverse) . gcc could be extended to generalize the binary patching technique used in the Linux kernel for use for any application. What this provides is variable optimized run time multiverse support. Technical feasibility Its known in theory this should technically be possible given that: * variable attributes exist, this would be used * functions can be cloned, even with special variable settings Example Let's consider the simple case of using a bool which only has two possible values: * true * false Code that would want to make use of this would annotate that the bool can be optimized for binary patching using a special attribute, for instance: >static __attribute__((multiverse)) bool some_value; int foo(void) { if (some_value) { do_a(); } else { do_b(); } } int main(int argc, char **argv) { if (argc > 1) some_value = true; gcc_runtime_optimize_variable(&some_value); } In this example when gcc would see some_value has the multiverse annotation, it would clone the foo() function twice, for two different possible universes , one where some_val is true, and one where some_val is false. The references to the some_val locations in code are also stored for later use (generic some_val use, where some_val = true, some_val = false) in a special section to allow for run time patching. Applications get to hint during run time when a variable is deemed stable, this means that the variable value will not change for either: * a very long time * forever If an application, or the kernel, determines that a configuration variable is now deemed "stable", it can enable the application to put itself into an application specific safe state (for instance perhaps disallow concurrent threads, disable preemption, perhaps machine_stop() in the kernel). After this application specific safe-state call, a generic function would be called that would run time patch either the first few bytes of some generic functions or all invocations of the generic functions with the specialized variant for the current value of some_val. Benefits Benefits once this happens: * code executes and performs runs as efficienbtly as if some_val would have just been a const bool, or as if some_val would never had needed to be runtime determined * no register clobbering * no [id]cache pollution * ability to identify and compartmentalize dead-code * ability to decide how to handle dead-code at run time: * freeing unused code after variable stable state is reached * ability to enable debugging phase to ensure code that should not runs does not run, for instance by marking dead-code as not present Negative effects Expected negative effects to consider: * function cloning would increase the final size of a binary * due to size impact, use of this functionality should be limited Use Case: Potential uses Expected potential uses: * Linux's UP/SMP patching * Linux's pv-ops * Linux's alternative patching based on cpu features * QEMU's kvm_enabled(), xen_enabled(), etc * user space JIT with runtime cpu feature detection * anything that wants to optimize for cpu features * dpdk network filter features Business case (Partner benefit): - An evaluation of business impact is not yet done, this work is being - considered due to the parallels in gains accepted that is known to - exist for qemu as with the work that is being done to address dead-code - for Xen due to the switch to pvops to support Xen on Linux. A business - evaluation of impact of the gains of this can be assessed once tools - are written to help evaluate the amount of dead-code in a project at - run time. At least one public evaluation (https://www.internetsociety.org/sites/default/files/Presentation03_2.pdf) + openSUSE.org: An evaluation of business impact is not yet done, this + work is being considered due to the parallels in gains accepted that is + known to exist for qemu as with the work that is being done to address + dead-code for Xen due to the switch to pvops to support Xen on Linux.

At least one public evaluation (https://www.internetsociety.org/sites/default/files/Presentation03_2.pdf) has been done already to quantify the amount of dead-code, evaluated as exposed code attack surface, this evaluation concludes that at least on the Linux kernel a tailored kernel which removes not needed or unused kernel configuration and therefore access to run time code, reduces the attack surface by 85%. -- openSUSE Feature: https://features.opensuse.org/320868

[New: openFATE 312491] Explicit IPv6 support for YaST printer module
by fate_noreply＠suse.de 11 May '16

11 May '16

Feature added by: Johannes Meixner (jsmeix) Feature #312491, revision 1 Title: Explicit IPv6 support for YaST printer module openSUSE Distribution: Unconfirmed Priority Requester: Mandatory Requested by: Johannes Meixner (jsmeix) Partner organization: openSUSE.org Description: Currently there is not any kind of special IPv6 support in yast2-printer. Currently IPv6 works only where it is compatible to IPv4 but there are cases where IPv6 needs special handling: For example the tests whether or not a remote host is accessible run "ping <IP-address or hostname>" which fails if IP-address is an IPv6 address because for IPv6 ping6 must be used. See https://bugzilla.novell.com/show_bug.cgi?id=697833 Unfortunately ping6 cannot be used for IPv4 addresses so that yast2-printer needs to implement special distinction of cases in particular if a hostname is given depending on whether or not this hostname has an IPv4 or IPv6 address or both. Probably there are some more special distinction of cases needed to distinguish between IPv4 and IPv6 stuff. -- openSUSE Feature: https://features.opensuse.org/312491
