2016-10-19kern-tools: make patches with shell-unsafe characters validBruce Ashfield
If a patch contains characters like ; or (), it can cause processing errors in the patch queue. We had previously fixed this issue by renaming the patches to not include invalid characters, but with this change to the kern tools that ensures patch names are wrapped in quotes, we avoid shell processing and hence they are valid.

2016-08-18kernel-yocto: streamline patch, configuration and audit phasesBruce Ashfield
We've been running with a set of kern-tools that were designed to work with build systems that knew nothing about git, trees, commits, etc. As such, there's been a set of shims/wrappers in place to work with within bitbake/oe-core. These were the *me scripts: createme, updateme, patchme and configme. With this commit, we strip that legacy code and use the tools directly. This means less complexity, fewer corner cases .. and no surprises when the tools are arunning. As another benefit, the tools consume much less time during a typical build and have no noticeable impact on the overall build time. Existing .scc files, features, and processing are not impacted as these tools are compatible with existing feature descriptions and kerne configuration fragments. The audit of kernel configuration fragments is now detached from the linux-yocto build structure and process. This means that they can eventually be tweaked to offer kernel audit to any type of kernel build and configuration process. Additionally, the kernel symbol audit phase can now resolve symbol dependencies and offer guidance when a symbol is missing: WARNING: linux-yocto-4.4.15+gitAUTOINC+b030d96c7b_f5e2c49d58-r0 do_kernel_configcheck: [kernel config]: specified values did not make it into the kernel's final configuration: ---------- CONFIG_BT_6LOWPAN ----------------- Config: CONFIG_BT_6LOWPAN From: /home/bruce/poky/build/tmp/work-shared/qemux86-64/kernel-source/.kernel-meta/configs/standard/features/bluetooth/bluetooth.cfg Requested value: CONFIG_BT_6LOWPAN=y Actual value: Config 'BT_6LOWPAN' has the following conditionals: BT_LE && 6LOWPAN (value: "n") Dependency values are: BT_LE [y] 6LOWPAN [n] Signed-off-by: Bruce Ashfield <bruce.ashfield@windriver.com> Signed-off-by: Ross Burton <ross.burton@intel.com>
2016-05-09kern-tools: handle directories with, or without, trailing /Bruce Ashfield
Robert P. J. Day reported that configuration fragments and kernel features were not being found when organized in a particular manner: linux - $BOARD - mm.patch - mm.scc - ssd_sil.cfg - ssd_sil.patch - ssd_sil.scc - uio.cfg .. etc There was a bug in the tools that did not handle the mix of subdirs properly and ended up leaving a trailing / on the elements *not* in the $BOARD subdir. As a result, the configuration fragments were not properly found when searching the include paths, and a configuration failure was triggered (due to missing files). This change tweaks the tools to always check a path with and without a trailing / when processing config fragments so they can be later found when processing the configuration of the kernel.

2015-10-24kern-tools: avoid duplicate .scc file processingBruce Ashfield
With the recent changes to improve patch processing times, the ability to skip already applied patches is not active by default. The automatic detection and resume was hiding issues with the include files generated by scripts like yocto-bsp. If a .scc file that contains a patch is included twice, the patch is applied twice, and the second appliation fails for obvious reasons. We can partially fix this by ensuring that already included configuration fragments are not forced into the meta-series. .scc files that are explicitly listed twice will continue to fail, and recipes must be modified to avoid this.

2015-10-01kern-tools: fix multi-layer patch applicationBruce Ashfield
Updating the kern-tools SRCREV to import the following fix: kgit-meta: resume after last applied patch When the auto-resume (resume point detection) was removed from the processing of a meta-series, it ignored the fact that a single patch series may in fact be processed a number of times. Two layers patching a kernel will generate two different runs on the same branch, which always start at patch one. This will obviously break with duplicate patches. To avoid this, we simply track the last patch applied, and explicitly tell the patch scripts where to start. This gets us resume functionality, without the overhead of resume point detection.

2015-09-19kern-tools: optimize patching peformanceBruce Ashfield
Updating the kern-tools SRCREV to integrat the following commit: patching: only validate user supplied patches by default Previously the patching tools would consider both system and user supplied patches in the same manner .. they are simply a series of patches to be applied to a branch, and that the scripts should determine where in the series to start (based on what is already on the branch). This detection was causing a few problems: - time consuming - starting in the middle of a series when intermediate patches were merged to a branch. To solve both the performance and start detection, we instead simply note the transition from system (i.e. already defined features and series) and user/recipe supplied patches. When the transition is noted, the system will start pushing ALL patches without doing autoresume detection. Control in keeping the series up to date is passed to the user, and consistent behaviour/performance is achieved.

2015-04-28kern-tools: unify meta directory detectionBruce Ashfield
It is possible that recipe specific tasks, or build processes drop files into the kernel source directory. These files can cause problems with the meta data detection in the kern-tools. With this change, we have a single unified meta data detection routine, that logs the result in a new file ".metadir", which subsequent scripts can find, and use, thereby avoid repeating the same check many times. We also enhance the check to look for a sentinel file in a proper meta directory, to avoid false positives when an unexpected kernel process leaves an uncommitted directory in the kernel dir.

2015-03-20kern-tools: fix iterative configuration runsBruce Ashfield
When fixing a kernel configuration warning, it is often necessary to modify the kernel's meta-data and re-run the tools to update and re-audit the config. This implies that the patch, config and audit steps are run multiple times. The tools had a bug that would incorrectly restore old meta-data versus using updated configuration.

2015-02-20linux-yocto: make kernel configuration audit user visibleBruce Ashfield
After a linux-yocto style kernel is configured, a kernel configuration audit is executed to detect common errors or issues with the config. This output used to be visible, but was made less obvious to not alarm users unnecessarily (since some configuration issues are acceptable). There are some classes of configuration issue that are worth being visible, and that is specified configuration values that do not make the final .config. These dropped options can result in any number of runtime failures, so flagging them at build time makes sense. The visibility of auditing is controlled by KCONF_AUDIT_LEVEL: 0: no reporting 1: report options that are specified, but not in the final config 2: report options that are not hardware related, but set by a BSP The default level is 1, with level 2 and above being for BSP development only. If these conditions are detected, warnings will be generated as follows: WARNING: [kernel config]: specified values did not make it into the kernel's final configuration: Value requested for CONFIG_SND_PCSP not in final ".config" Requested value: "CONFIG_SND_PCSP=y" Actual value set: "" or WARNING: [kernel config]: BSP specified non-hw configuration: CONFIG_BLOCK CONFIG_CFG80211_WEXT CONFIG_CORDIC CONFIG_CRC8 CONFIG_EFIVAR_FS CONFIG_EFI_PARTITION CONFIG_NET CONFIG_NETDEVICES CONFIG_PARTITION_ADVANCED CONFIG_WEXT_CORE CONFIG_WEXT_PROC CONFIG_WIRELESS At this point thse are only a warnings, since there needs to be time for layers and configuration fragments to be validated against this new check.

2014-10-01kern-tools: fix overly greedy path relocationsBruce Ashfield
During patch processing a consolidated set of configs, patches and directives is created under the kernel source tree being modified. During that processing, absolutely paths are converted to relative. It has been found that if directories are sufficiently similar, like so: /path/to/my-linux /path/to/my-linux-3.16 The processing will chop to much of some paths, resulting in invalid relative directories (like -3.16 in the above example).

2014-09-01kern-tools: allow meta branch and meta data directory to differBruce Ashfield
From the kern-tools commit: tools: allow meta directories that are not the same as the branch name With this change it is now possible to have a meta branch with meta data in a directory that is not the same name as the branch. The changes to three parts of the build are required to discover the name of the meta directory by relying on the fact that in a clean/proper build the meta directory is the only untracked, top level directory in the build. As such, we can restore a checkpoint and then examine the build directory to determine the meta directory name .. avoiding any new variables to indicate this to the scripts and build system.

2013-09-24kern-tools: fix multi patch application without headersBruce Ashfield
Updating the kern-tools SRCREV to import the following change: kgit-s2q: always update ORIG_HEAD after applying changes In situations where git am fails to apply patches, and git apply is used, we must update ORIG_HEAD as well as HEAD. This is required, since if the next patch in the queue also fails git am application, it will reset to ORIG_HEAD before using git apply. If we haven't updated ORIG_HEAD, we'll end up warping back to the top of the branch each time. This problem can only be seen in very specific situations, in particular if a generated BSP branches from qemuppc, and has a series of non git "am able" patches. We fail, since all of the qemuppc patches are not applied due to the branch head constantly being reset.

The same type of commit with kgit-s2q will prompt for a author ID, just as git-quilt-import does. In build system environment that leads to an infinite loop and the commit is never pushed. To fix this issue, we add an interactive flag (-i), that when passed the prompt based behaviour is used. When it isn't passed (the default), the following name and email will be used for the git author: GIT_AUTHOR_NAME="invalid_git config" GIT_AUTHOR_EMAIL="<unknown@unknown>" And a bare/incomplete header patch will be applied.

To do this, it first checks for an existing board description and generates one if required. It then searches for features and fragments to be applied for the tree. There were two problems: - A top level board description is detected via the presence of "define" directives that indicate the board name, the arch and kernel type. The test for define would match on patches or fragments with 'define' in their name, and would incorrectly use that file as the top level board description. This is fixed by ensuring that only defines at the start of a line, or preceded by whitepace match. - When searching for features that were indicated as 'addon' or 'optional', the search would find, and apply, any feature with the passed name as substring versus an exact match.

The location of the generated file is placed in the top_tgt file, which is used by subsequent stages. A relative path was being placed into top_tgt, which binds the build to a particular directory structure and working directory.

Additionally, the regex that detected flags passed to includes was not specific enough, and unfortunately named feature files would match.

2013-04-10kern-tools: fix excluded configuration processingBruce Ashfield
One of the features introduced early on in the 1.4 release cycle was the ability to include a kernel feature, but only get its patches and not configs (and vice versa). As it turns out, this only was exercised recently and once a single include with dropped configs was started, ALL configuration values following the commit were dropped. To fix the problem, the processing of kernel features has been split into two. Where the features are preprocessed and the assembled/complete file is used to generate the meta-series (which is later applied to the tree). The logic of the tools is the same, but the two phases of processing allows configuration values to be excluded properly and simply, while keeping the logic for modifying the tree in a separate step. All changes are invisible to the user, and are done within the existing scripts and build system bindings. Output series and manipulations to the tree are the same as they were before this change.

Updating the kern-tools SRCREV to import the following fixes: commit 7f91d198d32fc90260e52724ef4aac0b997c1e8b kconf_check: fix new Kconfig detection One of the functions of the kernel configuration audit is to notify the user if Kconfig* files have been removed from the kernel, and also to notify of new Kconfig files. New Kconfig files should be classified as hardware or non-hardware to allow BSP audits to notify if boards are setting values that they shouldn't, hence why notifying about new "buckets" is important. commit c4f26a3296e0e1c3dbdd5ec8e2947d5443a9ffc2 updateme/scc: allow config fragment exclusion It is common to need the features (patches, git operations) of a branch, but not want the kernel configuration fragments of a given branch. To allow this, we provide a new include flag "nocfg". When this flag is used, all of the configuration fragments included by the targetted feature will not be applied to the current build, with one exception, a base/critical fragment can force it's config values, since without them, the system would not be functional. Example: include ktypes/standard/standard.scc nocfg commit c7ec19d55aca6c4b17073c5362fce5be61a89d82 scc: wrap git merge To allow for parameter validation and sanity checking, wrap "git merge" as a dedicated "merge" command instead of using the raw git fallback.

2013-02-04kernel-yocto: allow multiple / shared kernel feature directoriesBruce Ashfield
To promote the reuse and sharing of configuration fragments this change allows any kernel-yocto based recipe to have multiple alternate git repositories which provide kernel feature directory trees listed on the SRC_URI. These feature directories are in addition to any in-tree kernel meta data branches that may be available (described via the KMETA variable in linux-yocto recipes). Features found within these directories can be used from recipes via the KERNEL_FEATURES variable. Features found within a feature directory are free to include any other features that are available in any directories. In both cases the path to a feature description (a .scc file) is relative to the root of a given feature directory (which is how existing .scc files work) The search order for features is determined by the order that repositories appear on the SRC_URI. Normal SRC_URI rules apply to any repository that is added as a kernel feature container. A SRCREV must be supplied and it must be unpacked to a unique directory, which is controlled via the "destsuffic" url parameter. In addition to these standard requirements, any kernel feature repository reference should identify itself via the "type=kmeta" url parameter. If type=kmeta is not supplied, the repository will not be processed for kernel features. As an example, the following in a linux-yocto bbappend makes two additional feature directories available to KERNEL_FEATURES and fragments. SRC_URI += "git://git.yoctoproject.org/yocto-kernel-cache;protocol=git;branch=master;type=kmeta;name=feat1;destsuffix=kernel-cache/" SRC_URI += "git://${KSRC_linux_yocto_3_4};protocol=file;branch=meta;name=feat2;type=kmeta;destsuffix=kernel-features-experimental/" SRCREV_feat1 = "${AUTOREV}" SRCREV_feat2 = "${AUTOREV}" Signed-off-by: Bruce Ashfield <bruce.ashfield@windriver.com> Signed-off-by: Saul Wold <sgw@linux.intel.com>

2012-11-19kern-tools: flexibility and usability enhancementsBruce Ashfield
Updating the SRCREV to import the following changes. [updateme: find the board description with the highest score] This removes the requirement that a custom linux-yocto .scc file have define KTYPE <foo>, where <foo> is typically "standard". The tools can now match on a .scc file that only matches the board, but will still chose one that matches the board and kernel type, if available. [updateme: allow for tabs or spaces in defines] define KMACHINE<tab>$MACHINE was missed by the regex. [scc/kgit-meta: detect and avoid duplicating patching] To allow feature description to be included multiple times, they were previously split into -enable and 'patch' descriptions. With this change the patches will be detected as already included, and skipped automatically. Removing the need to do this split. It also cleans up the ability to warn about multiple includes. [kconf_check: add "verify" configuration fragment type] This adds the ability for a BSP to have a kernel configuration fragment that lists options that must be present. If they are not present it is a hard error. "required" is a similar fragment, but it adds them to the build, and audits them at the end, but does not abort the build if they are present. This is a minor distinction, but one that is useful when creating flexible, shared kernel config structures. [kconf_check: improve kernel audit report formatting] [kconf_check: perform validity checks on non-hardware options] [kconf_check: cleanups and verbose flag] The existing output was verbose and not always useful to the reader. This change makes the output more compact, audits non-hardware options and gives information [invalid (54)]: meta/cfg/preempt-rt/common-pc/invalid.cfg This BSP sets config options that are not offered anywhere within this kernel Signed-off-by: Bruce Ashfield <bruce.ashfield@windriver.com>

Bumping the kern-tools SRCREV to pickup the following change: [ kconf_check: fix find warning When searching for all available Kconfig files, kconf_check was using $meta_dir instead of $META_DIR. This resulted in a truncated path and the following warning: find: warning: -path $oe-path/linux/ will not match anything because it ends with /.

2012-09-14kernel-yocto: fix kernel configuration audit for custom yocto kernelsBruce Ashfield
It was reported that the kernel configuration checks for custom yocto kernels had the following output: NOTE: validating kernel configuration grep: /meta-series: No such file or directory grep: /meta-series: No such file or directory WARNING: Can't find any BSP hardware or required configuration fragments. WARNING: Looked at //cfg///hdw_frags.txt and //cfg///required_frags.txt in directory: //cfg// NOTE: Tasks Summary: Attempted 375 tasks of which 367 didn't need to be rerun and all succeeded. which is not inspire confidence in the output of the process. Completely inhibiting the check is one option to remove the messages, but that removes the ability see output, which can help move users to a better or more fully configured linux-yocto based kernel. To fix this, we have to ensure that the path to the meta-series is always valid, and that the tools can deal with not all files existing in the audit directory. Since custom yocto kernels do not set KMETA (they don't have a meta branch), we ensure that a default of 'meta' is passed to the audit ('meta' is always valid), and that kconf_check itself can deal with an incomplete set of input audit files. The net result is output like this (using a defconfig with invalid options for the kernel being built): NOTE: validating kernel configuration This BSP sets 19 invalid/obsolete kernel options. These config options are not offered anywhere within this kernel. The full list can be found in your kernel src dir at: meta/cfg/standard/qemux86/invalid.cfg There were 1 instances of config fragment errors.

Importing the following tools SRCREV: kgit-meta: exclude explicit branches from name calculations kernel branches are constructed during patching of the tree by constructing a '/' based hierarchy of names as each branch directive is encountered. But if a "branch $name $branchpoint" is used, the entire branch name is supplied so no additions to the hierarchy should happen.

2012-09-04linux-yocto: fix unapplied patch error messageBruce Ashfield
When patches fail to apply, the status of all pending patches should be exported to the logs and to the user. Currently, a missing export of GUILT_BASE makes it look more like an internal error, than a 'normal' patch failure: | [ERROR] unable to complete push | pending patches are: | Patches directory doesn't exist, try guilt-init With this variable exported, we have this: | [INFO] validating against known patches (qemux86-standard-meta) | error: patch failed: Makefile:2 | error: Makefile: patch does not apply | To force apply this patch, use 'guilt push -f' | [ERROR] unable to complete push | pending patches are: | links/files/0002-makefile-patch.patch Signed-off-by: Bruce Ashfield <bruce.ashfield@windriver.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
2012-09-04kern-tools: fix forced branchingBruce Ashfield
commit 7a79f7412 [linux-yocto: make KBRANCH the exception and not the rule] ensures that a request branch is always built. The implementation of this guarantee is a branch switch before the build starts. But that switch may be before all patches are applied. If the proper routines are not called, no patches can be applied to the tree. Updating the SRCREV to pickup this fix: updateme: use branch command when forcing branch switches When forcing a branch switch to the desired branch we should be using the proper 'branch' command. Since without this call, the proper variables will not be set, and patches can't be applied to the tree.

2012-08-19linux-yocto: make KBRANCH the exception and not the ruleBruce Ashfield
The kernel branch is no longer required by the yocto-kern-tools to locate BSP feature descriptions (it is the MACHINE:KTYPE descriptor), so we no longer require that the BSP branch be explicitly set. If a kernel branch is explicitly set, it is now used to trigger a checks to ensure that the branch really is being built. Otherwise the branch that the machine description creates will be built (just as it always was). This further simplies the use and configuration of a linux-yocto based kernel recipe.

2012-06-08kern-tools: anchor KMACHINE testBruce Ashfield
Updating the kern-tools SRCREV to pick up the following fix: Out of tree feature descriptions (.scc files) take two forms: normal features and BSP descriptions. A normal feature is detected and added to the end of the current machine being processed. During tree processing, it's configuration and patches will be applied. A BSP description on the other hand must be matched based on three critera (which are in the .scc file via "define <foo>"): - machine - kernel type - architecture Since features that define machines are only explicitly added, they are removed from the list of features that should be automatically added. The criteria for removing them from the auto-add list is the definitions found in the .scc file. The existing check was simply for KMACHINE anywhere in the file. This meant that a conditional or even a comment containing that phrase would exclude a file. Properly anchoring the KMACHINE test to "^define.*KMACHINE" fixes the problem of overly agreesive exclusions.

Updating the kern-tools SRCREV to pick up fixes that remove unused code, transition code (tree format changes) and to remove assumptions about branch and directory naming. There are no user visible changes with this update, but the plumbing changes will be used in future updates for more generalized support. The commit details are below: Author: Bruce Ashfield <bruce.ashfield@windriver.com> Date: Fri May 11 12:13:12 2012 -0400 kgit-publish: remove --remote option The ability to publish and automatically push a repository was never used, and is error prone. The complexit isn't needed in the script, so removing it is the best option.

So the cleanup and removal of the old structure can be completed. The meta branch and directory are now controlled via command line, or via the KMETA environment variable. No testing and conditional processing of the tree are required. Additionally, the generate_cfg script is no longer used, or is the branch conditing code in createme. So they can be safely removed from the tools and repository.

With this set of changes, simply passing the meta branch name is enough to sanitize and restore the checkpoint. If no meta branch name is passed, the default of 'meta' is used for both the branch and meta data directory name.

2012-05-09kern-tools: fix do_patch errorsBruce Ashfield
The linux-yocto repository and scripts can support a mode of meta data management that merges a base meta branch to every BSP branch. In this case, the scripts don't have to restore a checkpoint for the meta data to be globally accessible. The decision to restore or not is made based on whether or not the meta branch is part of all branches or not. The linux-yocto recipes have a sanity check to determine if the requested SRCREV for meta data matches the head of the meta branch (via do_validate_branches). If the wrong commit is at the head, the meta branch is moved aside and the branch reset to the right commit. This creates two meta branches that contain the base meta data. The test for integrated meta data mistakes this for a globally merged set of meta data and doesn't restore the checkpoint, which leads to build failures. The immediate fix is to allow two branches to have the meta data. The long term fix is to make the detection only consider if the build branch contains the meta data.
