| * ueventd fixup_sys_perms: fixup SELinux labels unconditionallyNick Kralevich2014-07-071-13/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | Currently, the fixup code in fixup_sys_perms() scans through all entries in uevent*.rc. If it finds a match, then it performs a fixup. If there's no match in that file, no fixup is performed. SELinux file labels are independently stored in /file_contexts, with no relationship to the files in /ueventd.rc. Even when no entries exist in ueventd.rc, we still want to fixup the SELinux file label in /sys when a uevent message occurs. Change-Id: I0ccb5395ec0be9282095b844a5022e8c0d8903ac

* init/ueventd: adds wildcard matching for ueventd rulesDaniel Leung2014-06-201-1/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The sysfs nodes can change from devices to devices for a particular class of peripheral. Some of them even change after suspend/resume, e.g. rfkill for USB bluetooth adapters. This patch adds to the way how ueventd rules with wildcard are handled. In addition to matching the prefix with a trailing wildcard, now rules can have wildcard anywhere in the rule. The wildcard matching is implemented using fnmatch(), where its matching is simliar to shell pathname expansion. It suits this particular usage model well. To avoid abuse, the number of slashes has to match between path name and the rule. For example, instead of creating a rule to match: /sys/devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.3/2-1.3:1.0/bluetooth/hci0/rfkill* , this would suffice: /sys/devices/pci0000:00/0000:00:1d.0/*/*/*/*/bluetooth/hci0/rfkill* The prefix matching behavior is retained, such that those rules do not have to pay for processing penalty with fnmatch().

* Extend ueventd to use the label-by-symlink support in libselinux.Stephen Smalley2014-06-161-3/+4
| | | | | | | | | | | | | | When ueventd creates a device node, it may also create one or more symlinks to the device node. These symlinks may be the only stable name for the device, e.g. if the partition is dynamically assigned. A corresponding change with the same Change-Id to external/libselinux introduces selabel_lookup_best_match() to support looking up the "best match" for a device node based on its real path (key) and any links to it (aliases). This change updates ueventd to use this new interface to find the best match for the device node when creating it.

* ueventd: support by-name symlinks for PCI block devicesAndrew Boie2014-05-131-6/+44
| | | | | | | | | | | | | | | | | To ensure that well-crafted removable media can't spoof the internal partitions, for platform devices the controller id is inside the generated path. We now do the same for PCI devices. The generated path has two levels; the PCI domain/bus, and then the peripheral ID. This lets us get by-name symlinks for PCI media, such as the SATA controllers on PC-like hardware. The symlinks will be created under /dev/block/pci/. For example: /dev/block/pci/pci0000:00/0000:00:1f.2/by-name/ Change-Id: Icee3e86bef5569c2bbd94c26bc00d49028345e3b Signed-off-by: Andrew Boie <andrew.p.boie@intel.com>

* init: add subsystem rules to ueventd.rcGreg Hackmann2013-11-261-29/+58
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | By default ueventd creates device nodes under /dev based on the ueventd DEVPATH. Several subsystems have special rules which are hardcoded in devices.c. Moving forward these special rules should go in ueventd.rc. Special rules have the syntax: subsystem <s> devname (uevent_devname|uevent_devpath) [dirname <dir>] Devices matching SUBSYSTEM=<s> will be populated under <dir>. dirname is optional and defaults to /dev. If dirname is provided, <dir> must start with "/". If devname is uevent_devname, ueventd will create the device node as <dir>/DEVNAME. DEVNAME may include intermediate subdirectories, which ueventd will automatically create. If devname is uevent_devpath, ueventd will use the legacy behavior of computing DEVPATH_BASE=basepath(DEVPATH), and creating the device node as <dir>/DEVPATH_BASE. The new parsing code is based on init_parser.c, with small tweaks to handle commands which don't fall under a section header.

* ueventd: Increase uevent buffer sizeAndrew Boie2013-01-041-2/+2
| | | | | | | | | | | | | As it turns out, no, 64K is not enough. A device provisioning tool was generating many uevents as it manipulated the GPT, causing events near the end of the process (including events as a result of the final BLKRRPART ioctl()) to get lost. It's not clear what the best value for this should be, but increasing to 256K fixed the problem in this case.

This can be triggered by setting the selinux.loadpolicy property to 1, whether from init.rc after mounting /data or from the system_server (e.g. upon invocation of a new device admin API for provisioning policy). ueventd and installd are restarted upon policy reloads to pick up the new policy configurations relevant to their operation.
