[opensuse-buildservice] Compiler Cache (Ccache) support in Open Build Service

by Sumit Jamgade

Hello, Long running compilation can now leverage ccache[1] to speed up the build process. This feature can be enabled per package in the project config: BuildFlags: useccahe:<packagename> example: https://build.opensuse.org/projects/home:sjamgade:branches:science:machinel… Once enabled per package, it will be enabled for all architectures and repositories. https://openbuildservice.org/help/manuals/obs-user-guide/cha.obs.prjconfig.… (grep ccache) --- The ccache tar file is collected only on *successful builds with changed result*. It is extracted for every build at /.ccache/ if enabled. This build artifact is not versioned and only the latest tar is stored. It can be downloaded from the webui or osc. https://build.opensuse.org/package/binaries/home:sjamgade:branches:science:… osc getbinaries --ccache -M standard home:sjamgade:branches:science:machinelearning tensorflow openSUSE_Tumbleweed x86_64 _ccache.tar osc getbinaries --ccache $prj $pkg $repo $arch _ccache.tar This archive can be further used for local builds too. osc build --pkg-ccache /full/path/to/_ccache. (please use the latest osc) --- Ccache config file is stored in /.ccache/ccache.conf and is writable by the build user. So, it could also be disabled (or configured as per package requirements) echo "disable = true" >> /.ccache/ccache.conf For possible build time comparisons: https://build.opensuse.org/packages/tensorflow:standard/job_history/home:sj… https://w3.nue.suse.com/~sjamgade/ccachereport.html Thank you, Sumit Jamgade and OBS Team [1] - https://ccache.dev/ PS: Some packages (eg: tensorflow) need extra plumbing in spec file to enable access to /.ccache and use of ccache cmd: export CC_PREFIX=ccache; ln -s /.ccache/ ~/.ccache -- To unsubscribe, e-mail: opensuse-buildservice+unsubscribe(a)opensuse.org To contact the owner, e-mail: opensuse-buildservice+owner(a)opensuse.org

[opensuse-buildservice] Short OBS downtime this Saturday

by Michael Schroeder

Hi OBS users, we need to do a little database maintenance on Saturday at 21:00 UTC. The buildservice will not be available for about 30 minutes. The build service will still schedule and finish builds in that time, but the API and the Web UI will not be available. Thanks for your understanding and have a nice weekend, Michael. -- Michael Schroeder SUSE Software Solutions Germany GmbH mls(a)suse.de GF: Felix Imendoerffer HRB 36809, AG Nuernberg main(_){while(_=~getchar())putchar(~_-1/(~(_|32)/13*2-11)*13);} -- To unsubscribe, e-mail: opensuse-buildservice+unsubscribe(a)opensuse.org To contact the owner, e-mail: opensuse-buildservice+owner(a)opensuse.org

[opensuse-buildservice] Issue with RSA signing in openSUSE:Factory:RISCV

by Andreas Schwab

At least since 2020-08-09 RSA signing of kernel modules is broken in openSUSE:Factory:RISCV, producing bad signatures that cannot be verified against the included certificate: $ modsign-verify -v -v --cert-dir etc/uefi/certs sunrpc.ko Signature type: pkcs#7 Signed by: cn=openSUSE Secure Boot CA,serial=1 Hash algorithm: sha256 Trying etc/uefi/certs/188EA6FA.crt Found matching certificate etc/uefi/certs/188EA6FA.crt RSA operation error 140060768991040:error:0407008A:rsa routines:RSA_padding_check_PKCS1_type_1:invalid padding:crypto/rsa/rsa_pk1.c:67: 140060768991040:error:04067072:rsa routines:rsa_ossl_public_decrypt:padding check failed:crypto/rsa/rsa_ossl.c:648: sunrpc.ko: signature validation failed for etc/uefi/certs/188EA6FA.crt sunrpc.ko: bad signature IIUC the signature appears to be created with a private key that doesn't match the public key in etc/uefi/certs/188EA6FA.crt. Since the problem does not occur if the same kernel is built in a different project, there is no fundamental problem with signature creation or verification. The last working kernel was built on 2020-08-01 in o:F:RISCV (which verifies properly using the same certificate). I note that the certificate has a serial number of 1. Isn't that serial number supposed to be unique?

[opensuse-buildservice] SCTP support

by Pau Espin Pedrol

Hi all, I noticed a few minutes ago that buildhosts seem to be unable to create SCTP sockets. For instance, a call to something like this would fail: fd = socket(AF_INET, SOCK_STREAM, IPPROTO_SCTP); So the socket call is returning -1 and strerror(errno) shows: "Protocol not supported" Which to me means the kernel in use doesn't seem to have sctp built-in or the host is somehow configured to prevent loading it. So now the question is, am I correct with my understanding? And if that's the case, is there any good reason to disable support for SCTP? Having no SCTP support in the kernel means I need to disable some unit tests of the package I'm building (libosmocore), which verify that APIs work well on different distributions (versions) and architectures.

[opensuse-buildservice] Problems with the aarch64 workers?

[opensuse-buildservice] best practices

by rinigus

Hi, I would like to push the maps apps that I develop to OpenSUSE OBS and would like to ask someone to review and give feedback regarding the approach. In the longer term, I am planning to build Nemo Mobile on the basis of OpenSUSE or Fedora / ARM as well. So, it would be great to get an approach checked before a larger number of packages will be converted from Sailfish OBS. As for my background, maps stack was developed originally for Sailfish and later ported to Linux desktop. All has been compiled and maintained on Sailfish OBS, which has a somewhat different setup and source services. In particular, I am interested in _service and rpm spec's. As an example, please consider https://build.opensuse.org/package/show/home:rinigus:scratchbox/rrdtool . This is just a small example which is used for learning and will be removed later. In my case, all or most of the packages are in git and contain RPM spec's. In the case of that example, it is a separate repo with the packaged code as a submodule - practice used for many Sailfish packages. The current _service is failing for me and I am not sure it is possible to get what I want: <services> <service name="obs_scm"> <param name="url">https://github.com/rinigus/pkg-rrdtool.git</param> <param name="scm">git</param> <param name="revision">suse</param> <param name="extract">rpm/*</param> <param name="filename">rrdtool</param> <param name="version">_none_</param> </service> <service mode="buildtime" name="tar" /> <service mode="buildtime" name="recompress"> <param name="file">*.tar</param> <param name="compression">xz</param> </service> </services> I would like source service to 1. pull sources from git (this works) 2. extract SPEC from pulled sources (this works) 3. not to mingle with the version and use version from SPEC 4. on build, create tar in format filename-version.tar.xz 5. unpack and use the same setup as was done before: %setup -q -n %{name}-%{version}/rrdtool in this case. I know that I can skip source packing into tar and then use "%setup -q -n %_sourcedir/%{name}/rrdtool -T -D" in SPEC as well specify _service as a source. Ideally, I would keep spec as it is and prepare through services. Is it possible? If it is, what should I change?

[opensuse-buildservice] What happened to my account?

by Eugen Block

Hi, I'm not sure if my message will already get through but I'll try anyway. I haven't logged into OBS for a while but I used to have an account. Now my login doesn't work anymore, is this related to the whole restructuring of SUSE in the last year? I get redirected to https://idp-portal.suse.com/univention/self-service/#page=passwordreset and apparently my username is not known to the system anymore. I'd appreciate if anyone could explain where my account is and how to enable it again. Or do I need to create a new account? I already have several and would like to avoid that if possible.

[opensuse-buildservice] KVM-based OBS workers

by Phil King

Are there more complete instructions for creating a KVM-based OBS worker? I am aiming for OBS workers based off of a minimal openSUSE base install (either the openSUSE Leap cloud image or NET .iso). I can get this to work with a VM install of the OBS appliance (I have both of the .iso and the .qcow2 installs working, as VMs. I do not have the .iso working as a bare metal install, which is confounding…). I would prefer my OBS workers are not full appliance installs. The best instructions I can find are via the code (dist/obsworker and dist/sysconfig.obs-server), namely: to ensure the qemu-kvm package is installed, and that virtualization is available (this requires the correct BIOS settings, and nested virtualization, in the case of a VM). elif [ -e /dev/kvm -a -x /usr/bin/qemu-kvm ] ; then Further, dist/sysconfig.obs-server offers this: # for KVM, you have to create with (example for openSUSE 11.2): # # export rootfstype="ext4" # mkinitrd -d /dev/null -m "ext4 binfmt_misc virtio_pci virtio_blk" -k #vmlinuz-2.6.31.12-0.2-default -i initrd-2.6.31.12-0.2-default-obs_worker # # a working initrd file which includes virtio and binfmt_misc for OBS in order #to work fine This is not proving sufficient. On the base openSUSE cloud images, qemu-kvm fires up, and then just hangs there, and eventually times out. There is very little in the way of error messaging or logs here. Digging further, on an existing OBS appliance install, I find a more complete list of kernel modules here (/etc/dracut.conf.d/03-my-obs.conf), but "zypper wp ..." ("what provides") on that file does not reveal anything. Also, this file does not seem to be in the open-build-service git repo. force_drivers+="loop dm-mod dm-snapshot binfmt-misc fuse kqemu squashfs ext2 ext3 ext4 reiserfs nf_conntrack_ipv6 binfmt_misc virtio_pci virtio_mmio virtio_blk virtio-rng fat vfat nls_cp437 nls_iso8859-1 ibmvscsi ibmvscsic" This longer list indicates that there might be more complete instructions floating around that I can not find. Can someone clarify what additional packages are needed on top of an openSUSE base install in order to get KVM-based OBS workers? (If documentation for this does not exist, if someone could guide me here, I would be happy to write a draft of that documentation. --- Phil King phil(a)cpanel.net -- To unsubscribe, e-mail: opensuse-buildservice+unsubscribe(a)opensuse.org To contact the owner, e-mail: opensuse-buildservice+owner(a)opensuse.org

[opensuse-buildservice] Add external source to a package?
