* package/ifupdown-scripts: new packageYann E. MORIN2017-07-044-21/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | The ifupdown scripts can be used independently of the init system, be it sysv, busybox or systemd; they could even be used when there is no init system (i.e. the user is providing his own). Currently, those ifupdown scripts are bundled in the skeleton. But we soon will have a skeleton specific to systemd, so we would be missing those scripts (when systemd-networkd is not enabled). So, move those scripts to their own package. To keep the current behaviour (before it is changed in future commits), we make that package default to y, but depend on the default skeleton. Instead of being a target-finalize hook, the scripts are installed as any other package are, with a package install-target command. Signed-off-by: "Yann E.

* system: introduce BR2_SYSTEM_ENABLE_NLSThomas Petazzoni2017-07-041-0/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Until now, the option BR2_ENABLE_LOCALE was more-or-less controlling whether NLS support was enabled in packages. More precisely, if BR2_ENABLE_LOCALE=y, we were not doing anything (so some packages could have NLS support enabled, some not). And only when BR2_ENABLE_LOCALE was disabled we were explicitly passing --disable-nls to packages. This doesn't make much sense, and there is no reason to tie NLS support to locale support. You may want locale support, but not necessarily NLS support. Therefore, this commit introduces BR2_SYSTEM_ENABLE_NLS, which allows to enable/disable NLS support globally. When this option is enabled, we pass --enable-nls to packages, otherwise we pass --disable-nls. In addition, when this option is enabled and the C library doesn't provide a full-blown implementation of gettext, we select the gettext package, which will provide the full blown implementation. It is worth mentioning that this commit has a visible impact for users: - Prior to this commit, as soon as BR2_ENABLE_LOCALE=y, packages *could* provide NLS support. It was up to each package to decide whether they wanted to provide NLS support or not (we were not passing --enable-nls nor --disable-nls). - After this commit, it's BR2_SYSTEM_ENABLE_NLS that controls whether NLS is enabled or disabled, and this option is disabled by default. Bottom line: with the default of BR2_SYSTEM_ENABLE_NLS disabled, some packages may lose NLS support that they used to provide. But we believe it's a reasonable default behavior for Buildroot, where generally NLS support is not necessary.

* system: require a timezone to be setYann E. MORIN2017-07-041-3/+1
| | | | | | | | | | | | | | | | | | | | | | | Even though no timezone implicitly means UTC, systemd is not all that happy when it does not have a timezone set. This is all fine on a RW filesystem because systemd will create a symlink on its own (to Etc/UTC), but not so much on a RO filesystem, causing all kind of issues at boot time (up to the point that the system is unusable). We fix that by requiring that the timezone is actually set. The check is done by verifying that the timezone file is an actual file; if not set, the test would find a directory and would thus fail. Update the help entry accordingly. Also fix indentation in tzdata. Signed-off-by: "Yann E.

* system: do not overwrite /bin/sh Busybox symlinkThomas Petazzoni2017-03-291-1/+0
| | | | | | | | | | | | | | | | | | | | | | The BR2_SYSTEM_BIN_SH hidden option defines to what binary the /bin/sh symlinks should point to. If busybox is chosen, then /bin/sh is created to point to /bin/busybox. This works fine with the default installation mode of Busybox, but it fails with the upcoming "individual binaries" mode, in which each applet is installed as its own binary, and /bin/busybox doesn't exist: we get /bin/sh as a broken symlink to /bin/busybox. Since Busybox already installs its own /bin/sh symlink, properly pointing to /bin/ash or /bin/hush depending on the selected shell, it doesn't make sense for the BR2_SYSTEM_BIN_SH logic to override this. Just let Busybox install its own /bin/sh by making BR2_SYSTEM_BIN_SH empty when Busybox shell is selected as /bin/sh.

* skeleton: fix permissions on /dev/pts/ptmxJan Kundrát2017-03-181-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Without this patch, it is not possible to allocate PTYs when a generated rootfs image with a recent glibc and systemd is launched as a container on an RHEL7 system via machinectl/systemd-nspawn. The container boots, but `machinectl login mycontainer` fails. The culprit is /dev/pts/ptmx with 0000 perms. On a typical system, there are two `ptmx` devices. One is provided by the devpts at /dev/pts/ptmx and it is typically not directly accessed from userspace. The other one which actually *is* opened by processes is /dev/ptmx. Kernel's documentation says these days that /dev/ptmx should be either a symlink, or a bind mount of the /dev/pts/ptmx from devpts. When a container is launched via machinectl/machined/systemd-nspawn, the container manager prepares a root filesystem so that the container can live in an appropriate namespace (this is similar to what initramfs is doing on x86 desktops). During these preparations, systemd-nspawn mounts a devpts instance using a correct ptmxmode=0666 within the container-to-be's /dev/pts, and it adds a compatibility symlink at /dev/ptmx. However, once systemd takes over as an init in the container, /lib/systemd/systemd-remount-fs applies mount options from /etc/fstab to all fileystems. Because the buildroot's template used to not include the ptmxmode=... option, a default value of 0000 was taking an effect which in turn led to not being able to allocate any pseudo-terminals. The relevant kernel option was introduced upstream in commit 1f8f1e29 back in 2009. The oldest linux-headers referenced from buildroot's config is 3.0, and that version definitely has that commit. Mount options that are not understood by the system are anyway ignored, so backward compatibility is preserved.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As recently discussed on lwn.net: https://lwn.net/Articles/695478/ The kernel has special behaviour for uid/gid 65534: 1. The kernel maps UIDs > 65535 to it when some subsystem/API/fs only supports 16bit UIDs, but a 32bit UID is passed to it. 2. it's used by the kernel's user namespacing as the internal UID that external UIDs are mapped to that don't have any local mapping. 3. It's used by NFS for all user IDs that cannot be mapped locally if UID mapping is enabled. Most distributions already map (or are in the progress of changing) nobody/nogroup to the 65534 uid/gid, so lets do so as well.

* Makefile: drop ldconfig handlingThomas Petazzoni2016-01-031-0/+0
| | | | | | | | | | | | | | | | | | | | | | | | | The ldconfig handling in the main Makefile is utterly broken, as it calls the build machine ldconfig to generate the ld.so.cache of the target. Unfortunately, the format of the ld.so.cache is architecture specific, and therefore the build machine ldconfig cannot be used as-is. This patch therefore simply drops using ldconfig entirely, and removes /etc/ld.so.conf.d/ from the target skeleton. The idea is that all libraries that should be loaded by the dynamic linker must be installed in paths where the dynamic linker searches them by default (typically /lib or /usr/lib). This might potentially break a few packages, but the only way to know is to actually stop handling ldconfig. In order to be notified of such cases, we add a check in target-finalize to verify that there is no /etc/ld.so.conf file as well as no /etc/ld.so.conf.d directory.

* skeleton: optionally wait for network interfaces to appearJérôme Pouiller2015-11-021-0/+21
| | | | | | | | | | | | | | | | | | | | | | This patch has same purpose than 49964858f45d2243c513e6d362e992ad89ec7a45: On some machines, the network interface is slow to appear. For example, on the Raspberry Pi, the network interface eth0 is an ethernet-over-USB, and our standard boot process is too fast, so our network startup script is called before the USB bus is compeltely enumerated, thus it can't configure eth0. Closes #8116. However, wait-delay hook is enabled only if wait-delay property appears in /etc/network/interfaces. This patch enable it automaticaly when interface is configured through DHCP at bootup. But, if user choose to write /etc/network/interface himself, he have to explicitly set wait-delay.

* system: add options for /bin /sbin and /lib to be symlinks into /usrYann E. MORIN2015-10-144-0/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | systemd is increasingly expecting things to live in /usr/bin, /usr/sbin or /usr/lib nad not in /bin, /sbin or /lib. It has inherited those expectations from a Fedora change: https://fedoraproject.org/wiki/Features/UsrMove Note however, that systemd does support /usr being on a separate filesystem; it just expects an initramfs to mount it before the final switchroot over to the actual rootfs. But the traditional use-case for Buildroot is not to boot with an initramfs; although that is totally feasible, that's probably not what is commonly done in the vast majority of cases. However, a lot of packages still install stuff directly into /bin, /sbin or /lib, which systemd may need early-on in the boot process, even before it may have a chance to mount /usr. Even though we can tell systemd, at configure-time, where it should expect programs to be at runtime, it does not make sense to go head-first against an upstream wa^Hill. Add an option so that /bin, /sbin and /lib be symlinks to /usr/bin and /usr/sbin. That option is forcibly enabled when the init system is systemd. Note: we need not handle /lib32 or /lib64, as they already are symlinks to /lib, which means they will automatically be redirected to /usr/lib, as /usr/lib32 and /usr/lib64 already are. Furthermore, this means we're no longer supporting a split-usr setup, so the corresponding configure options have been removed as well for systemd and, when using a merged /usr, for eudev as well. In Buildroot, we decided (with this patch) not to support a split-usr when systemd is used as an init system. This is a design decision, not a systemd issue. Thus the select is with BR2_INIT_SYSTEMD rather than with BR2_PACKAGE_SYSTEMD. Signed-off-by: "Yann E.

| | | | | | | | | | | | | | | | | | | | | | | | | /dev/shm is needed for systems using shared memory. On init-based systems this directory is usually created in the inittab along with /dev/pts, by the lines: package/busybox/inittab: ::sysinit:/bin/mkdir -p /dev/pts ::sysinit:/bin/mkdir -p /dev/shm package/sysvinit/inittab: si2::sysinit:/bin/mkdir -p /dev/pts si3::sysinit:/bin/mkdir -p /dev/shm However this is broken when static /dev management is selected and the root filesystem is read-only, showing during boot the error: mkdir: can't create directory '/dev/shm': Read-only file system Fix it by creating the empty /dev/shm directory, just like /dev/pts.

The 'dirs' target, will create the $(TARGET_DIR). The file 'output/target/.root' doesn't exists anymore, as there's no Make rule to statisfy. The infrastructure are modified to filter host-skeleton. It's needed becauses the host-dependencies are derived from the dependencies of the target package where 'host-' is preprended to the depedency name. In the pkg-generic we add skeleton as a dependency to every package. The whole system/system.mk is now removed at the profit of package/skeleton/skeleton.mk [Thomas: - rebase on top of master and fix some minor conflicts - remove the 'select BR2_PACKAGE_SKELETON' in BR2_ROOTFS_SKELETON_DEFAULT and BR2_ROOTFS_SKELETON_CUSTOM, since anyway the skeleton package is always enabled. - fixup a few mistakes in the getty handling due to misnamed variables.] Signed-off-by: Maxime Hadjinlian <maxime.hadjinlian@gmail.com> Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>
