Vendor domains must not use Binder On PRODUCT_FULL_TREBLE devices, non-vendor domains (except vendor apps) are not permitted to use Binder. This commit thus: * groups non-vendor domains using the new "coredomain" attribute, * adds neverallow rules restricting Binder use to coredomain and appdomain only, and * temporarily exempts the domains which are currently violating this rule from this restriction. These domains are grouped using the new "binder_in_vendor_violators" attribute. The attribute is needed because the types corresponding to violators are not exposed to the public policy where the neverallow rules are. Test: mmm system/sepolicy Test: Device boots, no new denials Test: In Chrome, navigate to ip6.me, play a YouTube video Test: YouTube: play a video Test: Netflix: play a movie Test: Google Camera: take a photo, take an HDR+ photo, record video with sound, record slow motion video with sound. Confirm videos play back fine and with sound. Bug: 35870313 Change-Id: I0cd1a80b60bcbde358ce0f7a47b90f4435a45c95 2017-03-23 22:27:32 +01:00			`typeattribute modprobe coredomain;`
Minimize public policy Ideally, public should only contain APIs (types / attributes) for vendor. The other statements like allow/neverallow/typeattributes are regarded as implementation detail for platform and should be in private. Bug: 232023812 Test: m selinux_policy Test: diff <(git diff --staged \| grep "^-" \| cut -b2- \| sort) \ <(git diff --staged \| grep "^+" \| cut -b2- \| sort) Test: remove comments on plat_sepolicy.cil, replace base_typeattr_* to base_typeattr and then compare old and new plat_sepolicy.cil Change-Id: I5e7d2da4465ab0216de6bacdf03077d37f6ffe12 2024-03-27 09:18:41 +01:00
