ueventd: let scripts provide firmware directories Since some vendors will have firmware in mount points in /mnt/vendor/..., we extend the ueventd script language to allow specifying the firmware directories. Also, move the existing 4 directories to ueventd.rc as a primary user of this mechanism. Bug: 111337229 Test: boot sailfish; firmwares load Change-Id: I0854b0b786ad761e40d2332312c637610432fce2

firmware_directories /etc/firmware/ /odm/firmware/ /vendor/firmware/ /firmware/image/
ueventd: allow configuring SO_RCVBUF(FORCE) for the ueventd socket Some configurations won't allow ueventd to have CAP_NET_ADMIN, so the new default size of 16M is not possible for those. Those configurations also won't need such a large buffer size, so this change allows devices to customize the SO_RCVBUF(FORCE) size for the uevent socket. This is done by adding the line 'uevent_socket_rcvbuf_size <size>' to your device's ueventd.rc file. <size> is specified as a byte count, for example '16M' is 16MiB. The last parsed uevent_socket_rcvbuf_size line is the one that is used. Bug: 120485624 Test: boot sailfish Test: ueventd unit tests Change-Id: If8123b92ca8a9b089ad50318caada2f21bc94707

Permissions for /dev/uinput Currently /dev/uinput is owned by system/bluetooth. But that's inconsistent with some of the sepolicies for uhid_device. This also means that the new native tests for inputflinger aren't able to execute properly, because they require the ability to register a new input device via uinput.
