* init: fix write_file checkreqprot logic errorNick Kralevich2015-04-252-8/+10
| | | | | | | | | write_file() returned -errno on error, not -1. Callers who check for -1 would falsely believe that the write was successful when it wasn't. Fixup write_file so that it return -1 on error consistent with other functions. Change-Id: Ic51aaf8678d8d97b2606bd171f11b3b11f642e39
* init: remove mkdir /dev /proc /sysNick Kralevich2015-04-251-4/+0
| | | | | | | These directories are already present in the initial ramdisk, and these mkdir calls are no-ops. Change-Id: I528f9e96a3471de904845a2f9e09c1b6ff83a708
* Switch init to epoll.Elliott Hughes2015-04-248-87/+60
| | | | | | | | | | | Not just because it's what the cool kids are doing --- it also lets us simplify the inner loop and decouple it from whatever systems want to be woken to perform some activity if there's data to be read on some fd. Currently this is just used to clean up the existing signal handling, keychord, and property service code. Change-Id: I4d7541a2c4386957ad877df69e3be08b96a7dec5
* Clean up property service initialization.Elliott Hughes2015-04-242-43/+27
| | | | | | | | | | | All the code that was being delayed does is create a socket. We can do that straight away, avoid the overhead, and simplify our main loop. The keychord fd, on the other hand, seems a little tricky. It looks like /dev/keychord isn't immediately available, at least not on N9; we have to wait for ueventd to set us up the bomb.

* Clean up init signal handling a little.Elliott Hughes2015-04-242-50/+46
| | | | | | | We can set it up earlier, and error reporting like this helped me find the SELinux problem with the last change to this code. Change-Id: If0f38bc5ff0465c4030e2d39d34f31f49b2d8487

| * Setup signal handler before any exec commandJohan Redestig2015-04-181-1/+3
| | | | | | | | | | | | | | | | | | | | | | Fixes init deadlock when an exec command was called in an on-init section. The exec command handling relies on that the signal handler mechanism is working to know when to continue executing commands. Change-Id: Ib0ce75ffad7cf3bf926c93d0506b2fe3e5a92630
* | Revert "Revert "Remove now-unusable 'setcon' command.""Elliott Hughes2015-04-244-17/+0

* | Revert "Revert "Make init re-exec itself for its SELinux domain transition.""Elliott Hughes2015-04-241-14/+45
| | | | | | | | | | | | | | | | | | | | | | | | | | This reverts commit 4217374611ada50f33aee544f015f6f9dfbf7ced. It turns out that the kernel passes any unrecognized arguments on to init, and (at least) N6 and N9 have such arguments. My lazy check of argc was thus insufficient to recognize what stage of init we were in, so we'd skip to stage 2 and not set up SELinux. And apparently you can get a very long way with SELinux off... We'll fix that in a later change. Bug: 19702273 Change-Id: I43b3fb722fed35dd217cb529cbcac9a29aff4e4b
* | init: consider all platform devices for find_platform_deviceTom Cherry2015-04-231-10/+0
|/ | | | | | | | | | | | | | | | | | | | | | | Certain platforms list their platform devices with a path other than the current /devices or /devices/platform. Additionally, sometimes these paths are a platform device themselves. An example are devices with a path /devices/soc.0/... where /devices/soc.0 is also a platform devices. Instead of continuing to special case these path prefixes, we can consider the entire path, given that no mmc or usb devices create platform devices as subdevices, which they should not by their very nature. This keeps the symlinks for block devices named identically for current platform devices and places them in /dev/block/<full path to device> for devices in locations other than /devices or /devices/platform, eg /dev/block/platform/soc.0/7824900.sdhci This keeps the symlinks for character deviced named identically for all cases.

* Log more timing information from init.Elliott Hughes2015-03-2814-215/+251
| | | | | | | | | | | | | | | | | Also make important events in init's life NOTICE rather than INFO, and ensure that NOTICE events actually make it to the kernel log. Also fix the logging so that if you have a printf format string error, the compiler now catches it. Also give messages from init, ueventd, and watchdogd distinct tags. (Previously they'd all call themselves "init", and dmesg doesn't include pids, so you couldn't untangle them.) Also include the tag in SELinux messages.
