2014-12-24image.bbclass: avoid boot error on read-only systemd imageChen Qi
New version of systemd implements a new feature of updating /etc or /var when needed at boot. For details, please see link below. Opointer.de/blog/projects/stateless.html For now, at boot time, the systemd-sysusers.service would update user database files (/etc/passwd, /etc/group, etc.) according to the configuration files under /usr/lib/sysusers.d. This step is necessary for other systemd services to work correctly. Examples of such services are systemd-resolved and systemd-tmpfiles-setup. The problem is that on a read-only file system, that is, if /etc is read-only, the user database files could not be updated, causing failures of services. This patch fixes this problem by adding users/groups at rootfs time. Signed-off-by: Chen Qi <Qi.Chen@windriver.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>

2014-12-21classes/externalsrc: set do_compile as nostampPaul Eggleton
Most of the time what you want when using this class is for do_compile to execute more than just once - every time the source changes would be ideal, but that's a little tricky to accomplish. Thus, set do_compile as nostamp to get something close. Note that in order to be effective this also requires the change to bitbake that causes nostamp task signatures to change on each execution.

2014-12-21kernel: Fix non linux-yocto buildsRichard Purdie
After the recent kernel changes, non linux-yocto builds stopped working properly for two reasons: a) ${S} was being reset to ${WORKDIR}/git for example and STAGING_KERNEL_DIR did not contain the source b) Most builds were using ${B} == ${S} This patch adds a fixup to the unpack function to handle the case where ${S} != ${STAGING_KERNEL_DIR} and also set up the infrastrcture so that B != S for kernel builds from now on. The kernel build system is one of the best for supporting this and there is no good reason not to take advantage of it. Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
2014-12-20kernelsrc.bbclass: Ensure fetch/unpack/patch tasks don't runRichard Purdie

2014-12-20kernel: Clean ${S} before unpackRichard Purdie
Currently unpack just forces sources over the current files. This change ensures ${S} is cleaned out before sources are unpacked.

Ultimately, this should probably move to base.bbclass but one step at a time, this solves an immediate problem blocking the other patches from merging.

2014-12-20kernel-yocto: make sure git tags get dereferenced properly in do_patch()Jeff Wang
Commit 92c1ece6c347030d48995a36f4c67861356e59d3 causes the test in do_patch() in kernel-yocto.bbclass to fail if ${machine_srcrev} is an annotated tag. The check is meant to ensure that ${machine_srcrev} is an ancestor of HEAD, but if ${machine_srcrev} is a tag, then "$(git rev-parse --verify ${machine_srcrev})" evaluates to the SHA of the tag instead of what it's pointing to. Replacing "$(git rev-parse --verify ${machine_srcrev})" with "$(git rev-parse --verify ${machine_srcrev}~0)" fixed the problem by finding the object pointed to by the tag, and not the tag itself. This also works for commit IDs that are not tags, hence is safe in a scenarios. Jeff Wang <jeffrey.wang@ll.mit.edu> Signed-off-by: Bruce Ashfield <bruce.ashfield@windriver.com>
2014-12-20kernel-yocto: fix non-git buildsBruce Ashfield
The ability to build non-git repositories was broken by two changes: - The existence of an empty 'patches' directory created during the unpack phase. This dir was incorrectly identified as a valid meta directory and broke the build. By ensuring that it is removed before creating the empty repository, it will no longer be found instead of the real meta directory. - The attempt to reset the git repository to a specific SRCREV when no SRCREV was provided. By checking for a SRCREV of 'INVALID', we avoid any processing and failed git operations. Signed-off-by: Bruce Ashfield <bruce.ashfield@windriver.com>
2014-12-20kernel: fix out of tree module buildsBruce Ashfield

2014-12-20kernel: Rearrange for 1.8Richard Purdie
In 1.8 we want to streamline the kernel build process. Basically we currently have multiple copies of the kernel source floating around and the copying/compression/decompression is painful. Lets assume we have a kernel source per machine since in most cases this is true (and we have a sysroot per machine anyway). Basically, instead of extracting a source into WORKDIR, then copying to a sysroot, we now set S to point straight at STAGING_DIR_KERNEL. Anything using kernel source can then just point at it and use: do_configure[depends] += "virtual/kernel:do_patch" to depend on the kernel source being present. Note this is different behaviour to DEPENDS += "virtual/kernel" which equates to do_configure[depends] += "virtual/kernel:do_populate_sysroot". Once we do this, we no longer need the copy operation in do_populate_sysroot, in fact there is nothing to do there (yay). The remaining part of the challenge is to kill off the horrible do_install. This patch splits it off to a different class, the idea here is to have a separate recipe which depends on the virtual/kernel:do_patch and just installs and packages the source needed to build modules on target into a specific package. Right now this code is proof of concept. It builds kernels and kernel modules. perf blows up in do_package with issues on finding the kernel version which can probably be fixed by adding back the right bit of do_install, and adding a dependency of do_package[depends] += "virtual/kernel:do_install" to perf. The whole thing needs a good write up, the corner cases testing and probably a good dose of cleanup to the remaining code. Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
2014-12-20image: Avoid race over directory creationRichard Purdie

2014-12-19package.bbclass: do variable fixups even when FILES was setPeter Seebach
A number of settings (DESCRIPTION, SUMMARY, postinst, postrm, and appends to RDEPENDS) were made only if FILES_foo was not set for a given package. If you had a modified glibc packaging setup that was defining FILES_glibc-gconv-somelocale, this would prevent the automatic append of glibc-gconv as a dependency, because extra_depends was ignored. I think the assumption may have been that if FILES_foo was set, DESCRIPTION_foo and SUMMARY_foo would also be set, but it seems to me that the right answer is probably to set them if they aren't already set, and leave them alone if they are.

2014-11-25useradd.bbclass: set PSEUDO_PASSWD consistent with root directoryPeter A. Bigot
When installing into a sysroot this class examines $D/etc/passwd for content, then invokes useradd to make changes. Under pseudo useradd attempts to look up user information in directories specified by $PSEUDO_PASSWD. For opkg multilib installs $D is not always the same as $IMAGE_ROOT, and the user might already be in the IMAGE_ROOT files, causing a failure during rootfs population. Fix this by ensuring the files pseudo looks at when doing useradd stuff are the same ones that useradd.bbclass will be manipulating. Signed-off-by: Peter A. Bigot <pab@pabigot.com>

Fall back to the ${STAGING_DIR_NATIVE} version of those files until the rootfs versions are available.
