2015-07-24jail: fix jail root folder permissionsEtienne CHAMPETIER
We need a+x rights on the path to the root of the jails so we can use users other than root (like nobody) This partly fixes jailed dnsmasq Signed-off-by: Etienne CHAMPETIER <champetier.etienne@gmail.com>
2015-07-07service: if logging start app with LD_PRELOAD & lib for line bufferingRafał Miłecki
Using pipe automatically switches service to block buffering which kind of breaks our logging. We won't get anything from stdout FD until the buffer gets filled fully or the service exits. This makes log messages appear with an unwanted delay. This change adds a tiny libsetlbf.so switching stdout to line buffering and uses this lib for every logging-enabled service started by procd. We don't need any extra change for stderr as it's unbuffered by default. Signed-off-by: Rafał Miłecki <zajec5@gmail.com> Modified to use no buffering to align with stderr. Several cleanups.

2015-07-06Attempt to deal gracefully with allocation failures.Juliusz Chroboczek
These should probably not happen in practice, but having an explicit error message may make debugging out-of-memory situations easier.

2015-06-14hotplug: support for interval commandsRafał Miłecki
This allows executing code with a given interval. As every command, it can be assign to any uevent. Intervals may be useful for counting elapsed time since some action. It allows e.g. indicating that button has been pressed for some time. This is useful to let user know he can already release the button. Signed-off-by: Rafał Miłecki <zajec5@gmail.com>

2015-05-14jail: respect byte order when setting AUDIT_ARCHDaniel Golle
AUDIT_ARCH on ARM and MIPS differs depending on the byte order. Thus set AUDIT_ARCH to the respective endian-specific variants. Signed-off-by: Daniel Golle <daniel@makrotopia.org>
2015-05-14jail: add support for ARM architectureDaniel Golle
SECCOMP_FILTER isn't supported on ARM OABI. Thus enable seccomp support in jail only for EABI. thumb might work as well as it apparently implies EABI, but yet doesn't set __ARM_EABI__. The REG_SYSCALL macro seems to be an unused left-over. However, it's defined for other architectures as well. Signed-off-by: Daniel Golle <daniel@makrotopia.org>

2015-05-05instance: handle setgid() before setuid()Jo-Philipp Wich
When attempting to run a service with an unprivileged user and group id procd, the following error might occur: procd: failed to set uid:1000, gid:1000 This is due to the fact that procd first performs the setuid(), then the setgid() call. Usually there no sufficient permissions after a setuid() anymore to change the effective group id of the process. Refactor the code to: * Swap the invocations (first gid, then uid) * Don't set user or group id if it is 0 * Handle errors independently and make them more verbose Signed-off-by: Jo-Philipp Wich <jow@openwrt.org>

2014-11-04procd: Make askconsole work again when no tty is specified in inittabMichel Stam
Consider: ::askconsole:/bin/ash --login askconsole( ) checks for the existance of the tty, but if none is specified it will skip the remainder of the function. This means fork_worker( ) is never called and no process is spawned. This would leave routers without an initial console. Signed-off-by: Michel Stam <m.stam@fugro.nl>
