* procd: fix invalid JSON filter expression in procd_running()Jo-Philipp Wich2019-09-191-1/+1
| | | | | | | | | | Since service and instance names may contain characters which are not allowed in JSON path labels, such as dashes or spaces, change the filter expression to array square bracket notation to properly match these cases as well. Fixes: 2c3dd70741 ("procd: add procd_running() helper for checking running state") Signed-off-by: Jo-Philipp Wich <jo@mein.io> (cherry picked from commit c933b6d22478c1113629ef549beea6337f978d62)

* procd: allow passing optional group instance parameterMichael Heimpold2019-05-021-2/+3
| | | | | | | | | Sometimes is desirable to run a process with a specific group id instead of the default one which is derived from passwd entry. This can be achived now by using procd_set_param group $mygroup. Signed-off-by: Michael Heimpold <mhei@heimpold.de> Signed-off-by: Hans Dedecker <dedeckeh@gmail.com> [PKG_SOURCE_VERSION update]

* base-files/hotplug: fix dedicated group for tty devicesMichael Heimpold2019-04-041-0/+4
| | | | | | | | | | | | | | | | | Commit 124ab1dc0a and 5523ee3459 introduced the assignment of the group "tty" to /dev/tty* devices in order to support unprivileged user access to serial devices. However, due to an improperly rebased commit this feature broke. This patch restores the lost hunk in hotplug.json file to re-introduce this feature and also renames the existing "tty" group to "dialout" as this is the more typical name for such a group on desktop systems. Fixes: 5209cfa534 ("procd: fix hotplug.json syntax") Signed-off-by: Michael Heimpold <mhei@heimpold.de> Acked-by: Jo-Philipp Wich <jo@mein.io>
* procd: Add wrapper for uci_validate_section()Jeffery To2019-01-221-0/+17
| | | | | | | | | | | | | | | | | This adds a wrapper (uci_load_validate) for uci_validate_section() that allows callers (through a callback function) to access the values set by uci_validate_section(), without having to manually declare a (potentially long) list of local variables. The callback function receives two arguments when called, the config section name and the return value of uci_validate_section(). If no callback function is given, then the wrapper exits with the value returned by uci_validate_section(). This also updates several init scripts to use the new wrapper function.

* procd: remove procd-nand packageMatthias Schiffer2017-05-292-397/+0
| | | | | | | | | | | We always want to support staged upgrades now, so it's better to include upgraded into the main package. /lib/upgrade/nand.sh is moved to base-files.

* procd: fix default timeout for reload trigger actionsDenis Osvald2017-02-151-5/+2
| | | | | | | | | | | | | Default trigger action timeout was added to procd.sh in commit f88e3a4c0 (procd: add default timeout for reload trigger actions) However, the timeout value was not placed under the correct JSON-script array nesting level and thus did not apply. To fix this and make the timeout actually apply to the reload triggers, we place it in the correct scope, that is the per-trigger array.

* procd: update procd.sh to disallow signal-numbers, enforce signal-namesBastian Bittorf2017-01-261-1/+4
| | | | | | | | | | | | A given signal-name is now converted to the corresonding number. In general it's good style to use names (readability) and it's more portable: signal numbers can be architecture-dependent, so we are more safe giving names. A real world example is signal 10, which is BUS on ramips and USR1 on PPC. All users of 'procd_send_signal' must change their code to reflect this. Signed-off-by: Bastian Bittorf <bb@npl.de>

* sysupgrade: unmount filesystems before rebootMathias Kresin2016-08-041-0/+2
| | | | | | | | | | | | | | | sysupgrade immediately reboots after flashing an image and doesn't allow to unmount filesystems. At least in case the image used for sysupgrade is stored on a FAT formatted usb flash drive, the following warning is printed during the next mount of the flash drive: FAT-fs (sda1): Volume was not properly unmounted. Some data may be corrupt. Please run fsck. Although a data corruption during read operations is unlikely, there is no need to scare the users. Signed-off-by: Mathias Kresin <dev@kresin.me>

* procd: Set /dev/kmsg to 600neheb2016-07-021-4/+0
| | | | | | | | | | | Small cleanup. I initially though /dev/kmsg was used for dmsg(and journald on desktops) but this seems not to be the case. dmsg is still accessible as non-root(gives output) which begs the question what does this do? Some googling reveals that permissions are set to 600 for some embedded systems while 644 for others. I can't find any justification for the latter. Might as well err on the side of caution.

* procd: adjust /dev entries to desktop distro defaultsneheb2016-06-301-14/+4
| | | | | | | | | | | This changes the default permissions for /dev entries to be more similar to a desktop distro. Taken from the defaults of Arch Linux and Ubuntu. Also changed some that were nonsensical. For example, all 660 permissions on desktop distros were of the form root:x where x is something other than root. As such, 660 is useless for LEDE where the specific group is missing. audio seems to be the only group that isn't. Signed-off by: Rosen Penev <rosenp@gmail.com>
