* fs/common.mk: make sure that static devices from packages are createdThomas Petazzoni2018-12-041-1/+1
| | | | | | | | | | | | | | | | | | | The static devices defined by packages are currently added to the full device table when two conditions are met: (1) ROOTFS_DEVICE_TABLES is non-empty (2) BR2_ROOTFS_DEVICE_CREATION_STATIC=y (2) is obviously correct. However, depending on (1) is not correct: if the user doesn't provide any custom permission table and custom device table, then ROOTFS_DEVICE_TABLES will be empty. So instead, move the addition of the package-defined static devices outside of condition (1), and have it only under condition (2). Reported-by: "Yann E.

* fs/common.mk: rename FULL_DEVICE_TABLE to ROOTFS_FULL_DEVICES_TABLEThomas Petazzoni2018-12-041-5/+5
| | | | | | | | | | | | | | | | In commit 6b50f988ad0a6044530b30344d52139da2994237 ("fs/common.mk: rename internal variable"), USERS_TABLE was renamed to ROOTFS_FULL_USERS_TABLE. This commit follows the same direction by renaming the FULL_DEVICE_TABLE variable to ROOTFS_FULL_DEVICE_TABLE. In addition, for consistency, the file itself is renamed full_device_table.txt.

| * Makefile: rework main directory creation logicThomas Petazzoni2018-11-261-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In the current code, the creation of the main output directories (BUILD_DIR, STAGING_DIR, HOST_DIR, TARGET_DIR, etc.) is done by a global "dirs" target. While this works fine in the current situation, it doesn't work well in a context where per-package host and target directories are used. For example, with the current code and per-package host directories, the output/staging symbolic link ends up being created as a link to the per-package package sysroot directory of the first package being built, instead of the global sysroot. This commit reworks the creation of those directories by having the package/pkg-generic.mk code ensure that the build directory, target directory, host directory, staging directory and binaries directory exist before they are needed. Two new targets, host-finalize and staging-finalize are added in the main Makefile to create the compatibility symlinks for host and staging directories. They will be extended later with additional logic for per-package directories. Thanks to those changes, the global "dirs" target is entirely removed.

* | fs/tar: add support for xattrs (thus capabilties)Yann E. MORIN2018-11-201-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | By default, tar will not include any extended attribute (xattr) when creating archives, and thus will not store capabilties either (as they are stored in the xattr 'security.capability'). Using option --xattrs is enough to create a tarball with all the xattrs attached to a file. However, extracting all xattrs from a tarball requires that --xattrs-include='*' be used. This is not symetric (but on purpose, as per the documentation), and so is confusing to some. So, we use --xattrs-include='*' to create the archive, so as to be explicit that we want all xattrs to be stored. Signed-off-by: "Yann E.

* | fs: don't use an intermediate tarballYann E. MORIN2018-11-131-41/+18
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since 118534fe54b (fs: use a common tarball as base for the other filesystems), the filesystem creation is split in two steps, using an intermediate tarball to carry the generic, common finalisations to the per-filesystem finalisation and image creation. However, this intermediate tarball causes an issue with capabilities: they are entirely missing in the generated filesystems. Capabilities are stored in the extended attribute security.capability, which tar by default will not store/restore, unless explicitly told to, e.g. with --xattrs-include='*', which we don't pass. Now, passing this option when creating and extracting the intermediate tarball, both done under fakeroot, will cause fakeroot to report an invalid filetype for files with capabilities. mksquashfs would report such unknown files as a warning, while mkfs.ext2 would fail (with a similar error message), e.g.: File [...]/usr/sbin/getcap has unrecognised filetype 0, ignoring This is due to a poor interaction between tar and fakeroot; running as root the exact same commands we run under fakeroot, works as expected. Unfortunately, short of fixing fakeroot (which would first require understanding the problem in there), we don't have much options. The intermediate tarball was made to avoid redoing the same actions over and over again for each filesystem to build. However, most of the time, only one or two such filesystems would be enabled [0], and those actions are usually pretty lightweight. So, using an intermediate tarball does not provide a big optimisation. The main reason to introduce the intermediate tarball, however, is that it allows to postpone per-filesystem finalisations to be applied only for the corresponding filesystem, not for all of them. So, we get rid of the intermediate tarball, and simply move all of the code to run under fakeroot to the per-filesystem fakeroot script. Instead of extracting the intermediate tarball, we just rsync the original target/ directory, and apply the filesystem finalisations on that copy. The only thing still done in the rootfs-common step is to generate the intermediate files (users file, devices file) that are used in the fakeroot script. Fixes: https://bugs.busybox.net/show_bug.cgi?id=11216 Note: an alternate solution would have been to keep the intermediate tarball to keep most of the common finalisations, and move only the permissions to each filesystem, but that was getting a bit more complex and changed the ordering of permissions and post-fakeroot scripts. Once we bite the bullet of having some common finalisation done in each filesystem, it's easier to just move all of them. [0] Most probsably, users would enable the real filesystem to put on their device, plus the 'tar' filesystem, to be able to easily inspect the content on their development machine.

* fs/common: always depend on build host-tar if neededYann E. MORIN2018-11-011-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, the filesystems do not depend on building host-tar when it is needed, even though all of them have to extract the intermediate tarball. However, in degenerate (but legally valid) configurations with no user-selectable package selected, host-tar would not be built, so the rootfs images would use whatever improper tar the system has. Add the conditional dependency to host-tar to the rootfs-common intermediate image. Since this is the internal step that all real rootfs generators depend on, they now properly depend on host-tar when needed. In practice, when host-tar is needed, it will always be built before the rootfs images, because it is a dependency of all packages (except a very few, like the skeleton), of which host-fakeroot, which is a mandatory dependency of rootfs-comon anyway. But for consistency sake, let's explicitly add host-tar as a dependency to rootfs-common too. Note that rootfs-tar already had that dependency, and we leave it as-is because it is semantically correct, even if superfluous. Signed-off-by: "Yann E.

* fs/common: allow custom user table to override package-defined usersMatt Weber2018-10-201-1/+2
| | | | | | | | | | | | | | | | | | | | | Currently, when a custom user table and a package define the same user, the settings from the package takes precedence over the ones from the custom user table. However, it makes sense to allow the settings from the custom user table take precedence. For example, it would allow redirecting the user's home directory to an alternate location (e.g. away from tmp and into a partition that is persistent). The support/scripts/mkusers script will only retain settings from the latest definition it finds. Thus, by passing the custom user table after the package defined users, it is possible to override the package provided user definitions. Acked-by: "Yann E.

* fs: run packages' filesystem hooks in a copy of target/Yann E. MORIN2018-03-311-2/+5
| | | | | | | | | | | | | | | | | | | | Currently, some packages may register hooks to be run just before and just after the generic tarball image is generated, because they need to prepare the filesystem for read-only or read-write operation. However, this means that, if any of the hooks or the image generation fails, the target directory is left in a dangling, inconsistent state. We fix that by doing a copy of target/, run the hooks on that copy, generate the generic tarball image out of that, and get rid of the copy. This way, we can guarantee consistency of the target directory, and we can even ditch support for post-fs hooks (those that restore target/). Signed-off-by: "Yann E.

* fs: use a common tarball as base for the other filesystemsYann E. MORIN2018-03-311-28/+47
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, some filesystems may want to tweak the content of the target directory, create special device nodes etc... This all means that: - the content of the target directory for a specific filesystems may depend on whether another filesystem is enabled or not; for example, cpio will create a /init script or symlink and a /dev/console node; - the filesystems can not be built in parallel, because they may change the content of the target directory while another is being assembled. Furthermore, the same fakeroot script is executed over-and-over-again for each filesystem, to create the device nodes, the users and their homes and files, and setting permissions... We introduce an intermediate tarball, for which we do the full fakeroot shebang. That tarball then serves as the base for the other filesystems, with a very simple fakeroot script that untars the common tarball, and calls the actual filesystem image generator on that. Note that we use a very simple tar command to generate the intermediate tarball, because we are not concerned with reproducibility of the archive itself (only of the archived files).

* fs: set per-rootfs variable nameYann E. MORIN2018-03-311-0/+1
| | | | | | | | | | | | | | | | | | | | Like we do for packages with the PKG variable, set ROOTFS to contain the upper-case name of the rootfs currently being generated. This will be useful in later patches, when we need more per-rootfs variables, like a per-rootfs TARGET_DIR for example. In Makefiles, per-rule variables trickle down the dependency chain, to all dependencies of that rule, so we have to stop ROOTFS as soon as we're not in a rootfs. This means we have to stop it at target-finalize (which is a dependency of all filesystems), and for each package individually, since some packages (host or target) can be direct dependencies of filesystems as well.

* fs/cpio: don't extend packages' permissions tableYann E. MORIN2018-03-311-2/+4
| | | | | | | | | | | | | | | | | | | | | | | Currently, when we build a cpio filesystem without static devices, we shoehorn the /dev/console node as if it were specified by a package. This means that this device is added for all filesystems as well, not just the cpio. But if we disable cpio, that device is not created for other filesystems. This is not very clean, and may break expectations. Instead, use an explicit mknod as part of the _CMD, as we know it's going to run under fakeroot. This is still visible to all filesystems built after cpio, and not to those built before it, though. [Peter: ensure /dev exists, simplify comment] Signed-off-by: "Yann E.

* fs: run filesystem hooks under fakerootYann E. MORIN2018-03-311-1/+2
| | | | | | | | | | | | | | | | | | Currently, the pre-gen hooks of the various filesystems are run before we enter the fakeroot. However, this precludes those hooks from doing actions that require root, like creating a pseudo-device or the likes. So, move those pre-gen hooks under fakeroot. This has currently no side-effect, as they are still called before everything else in the fakeroot script, even the system-wide chown call. Signed-off-by: "Yann E.

* package/pkg-generic: handle host-tar as an extract dependencyThomas Petazzoni2018-03-251-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | This moves the host-tar dependency handling from DEPENDENCY_HOST_PREREQ to an extract dependency. To achieve that, check-host-tar.mk fills in the BR2_TAR_HOST_DEPENDENCY variable with host-tar if building a host-tar is needed. The name BR2_TAR_HOST_DEPENDENCY has been chosen because it matches the name BR2_CMAKE_HOST_DEPENDENCY already used in check-host-cmake.mk. The BR2_TAR_HOST_DEPENDENCY is added to all packages, except host-tar itself (obviously) and host-skeleton, because we depend on host-skeleton to install host-tar properly in HOST_DIR. In addition, we modify tar.mk to explicitly build host-tar without ccache: since ccache source code is available as a tarball, ccache will obviously depend on host-tar if the system tar is insufficient. Finally, to make things really clean, we also add $(BR2_TAR_HOST_DEPENDENCY) to the dependencies of the tar filesystem format, since it requires tar, so we'd better make sure we have a suitable tar.
