Add PLATFORM_SEPOLICY_VERSION. Create PLATFORM_SEPOLICY_VERSION, which is a version string to represent the platform sepolicy of the form "NN.m" where "NN" mirrors the PLATFORM_SDK_VERSION and "m" is a policy-based minor version that is incremented with every policy change that requires a new backward-compatible mapping file to be added to allow for future-proofing vendor policy against future platform policy. Bug: 36783775 Test: Device boots when sha256 doesn't match and compilation is forced. Change-Id: I4edb29824f2050a5a6e1bc078c100cf42e45c303

# PLATFORM_SEPOLICY_VERSION is a number of the form "NN.m" with "NN" mapping to
# PLATFORM_SDK_VERSION and "m" as a minor number which allows for SELinux
# changes independent of PLATFORM_SDK_VERSION. This value will be set to
# 10000.0 to represent tip-of-tree development that is inherently unstable and
# thus designed not to work with any shipping vendor policy. This is similar in
# spirit to how DEFAULT_APP_TARGET_SDK is set.
# The minor version ('m' component) must be updated every time a platform release
# is made which breaks compatibility with the previous platform sepolicy version,
# not just on every increase in PLATFORM_SDK_VERSION. The minor version should
# be reset to 0 on every bump of the PLATFORM_SDK_VERSION.

# SELinux policy version.
sepolicy: Drop BOARD_SEPOLICY_IGNORE/REPLACE support. With changes I431c1ab22fc53749f623937154b9ec43469d9645 and Ia54aa263f2245c7090f4b9d9703130c19f11bd28, it is no longer legitimate to use BOARD_SEPOLICY_IGNORE or REPLACE with any of the *_contexts files since the CTS requires the AOSP entries to be present in the device files. Further, these changes render BOARD_SEPOLICY_IGNORE unusable for most policy files since all domains and types referenced within any of the AOSP *_contexts entries must be defined in the kernel policy, so you cannot use BOARD_SEPOLICY_IGNORE to exclude any .te file that defines a type referenced in any of those *_contexts files. There does not seem to be a significant need for such a facility, as AOSP policy is small and only domains and types used by most devices should be defined in external/sepolicy. BOARD_SEPOLICY_REPLACE is commonly misused to eliminate neverallow rules from AOSP policy, which will only lead to CTS failures, especially since change Iefe508df265f62efa92f8eb74fc65542d39e3e74 introduced neverallow checking on the entire policy via sepolicy-analyze. The only remaining legitimate function of BOARD_SEPOLICY_REPLACE is to support overriding AOSP .te files with more restrictive rule sets. However, the need for this facility has been significantly reduced by the fact that AOSP policy is now fully confined + enforcing for all domains, and further restrictions beyond AOSP carry a compatibility risk. Builders of custom policies and custom ROMs still have the freedom to apply patches on top of external/sepolicy to tighten rule sets (which are likely more maintainable than maintaining a completely separate copy of the file via BOARD_SEPOLICY_REPLACE) and/or of using their own separate policy build system as exemplified by https://bitbucket.org/quarksecurity/build-policies Change-Id: I2611e983f7cbfa15f9d45ec3ea301e94132b06fa Signed-off-by: Stephen Smalley <sds@tycho.nsa.gov>

Add better per-device sepolicy support. This is a rewrite of the existing implementation. Three new variables are now needed to add/modify the exisitng base policy. They are, BOARD_SEPOLICY_REPLACE and BOARD_SEPOLICY_UNION which govern what files are replaced and concatenated, and BOARD_SEPOLICY_DIRS which lists the various directories that will contain the BOARD_SEPOLICY_REPLACE and BOARD_SEPOLICY_UNION policy files.

Drop BOARD_SEPOLICY_UNION. As suggested in the comments on https://android-review.googlesource.com/#/c/141560/ drop BOARD_SEPOLICY_UNION and simplify the build_policy logic. Union all files found under BOARD_SEPOLICY_DIRS. Unlike BOARD_SEPOLICY_REPLACE/IGNORE, on which we trigger an error to catch any lingering uses and force updating of the BoardConfig.mk files, we only warn on uses of BOARD_SEPOLICY_UNION to avoid breaking the build until all device BoardConfig*.mk files have been updated, and since they should be harmless - the files will be unioned regardless.

Split general policy into public and private components. Divide policy into public and private components. This is the first step in splitting the policy creation for platform and non-platform policies. The policy in the public directory will be exported for use in non-platform policy creation. Backwards compatibility with it will be achieved by converting the exported policy into attribute-based policy when included as part of the non-platform policy and a mapping file will be maintained to be included with the platform policy that maps exported attributes of previous versions to the current platform version. Eventually we would like to create a clear interface between the platform and non-platform device components so that the exported policy, and the need for attributes is minimal. For now, almost all types and avrules are left in public. Test: Tested by building policy and running on device. Change-Id: Idef796c9ec169259787c3f9d8f423edf4ce27f8c

# sepolicy is now divided into multiple portions:
# public - policy exported on which non-platform policy developers may write
# additional policy. types and attributes are versioned and included in
# delivered non-platform policy, which is to be combined with platform policy.
# private - platform-only policy required for platform functionality but which
# is not exported to vendor policy developers and as such may not be assumed
# to exist.
Device-agnostic policy for vendor image Default HAL implementations are built from the platform tree and get placed into the vendor image. The SELinux rules needed for these HAL implementations to operate thus need to reside on the vendor partition. Up to now, the only place to define such rules in the source tree was the system/sepolicy/public directory. These rules are placed into the vendor partition. Unfortunately, they are also placed into the system/root partition, which thus unnecessarily grants these rules to all HAL implementations of the specified service, default/in-process shims or not. This commit adds a new directory, system/sepolicy/vendor, whose rules are concatenated with the device-specific rules at build time. These rules are thus placed into the vendor partition and are not placed into the system/root partition. Test: No change to SELinux policy. Test: Rules placed into vendor directory end up in nonplat* artefacts, but not in plat* artefacts. Bug: 34715716 Change-Id: Iab14aa7a3311ed6d53afff673e5d112428941f1c

Fix build part 2. Always create platform_mapping_file. commit 552fb537129e9b446e79af53216c08d15e69144e fixed an undefined module error by removing the module when not defined (on non-treble devices), but the sepolicy build on non-treble devices was changed to rely on the split treble files, even though the split is not used. Change this so that the file is always present, to allow policy compilation. Test: policy fully builds. Change-Id: Ia0934c739336cea54228bbff8d6644aa3ae501e5

Split general policy into public and private components. Divide policy into public and private components. This is the first step in splitting the policy creation for platform and non-platform policies. The policy in the public directory will be exported for use in non-platform policy creation. Backwards compatibility with it will be achieved by converting the exported policy into attribute-based policy when included as part of the non-platform policy and a mapping file will be maintained to be included with the platform policy that maps exported attributes of previous versions to the current platform version. Eventually we would like to create a clear interface between the platform and non-platform device components so that the exported policy, and the need for attributes is minimal. For now, almost all types and avrules are left in public. Test: Tested by building policy and running on device. Change-Id: Idef796c9ec169259787c3f9d8f423edf4ce27f8c

# Builds paths for all policy files found in BOARD_SEPOLICY_DIRS.
# $(1): the set of policy name paths to build
Device-agnostic policy for vendor image Default HAL implementations are built from the platform tree and get placed into the vendor image. The SELinux rules needed for these HAL implementations to operate thus need to reside on the vendor partition. Up to now, the only place to define such rules in the source tree was the system/sepolicy/public directory. These rules are placed into the vendor partition. Unfortunately, they are also placed into the system/root partition, which thus unnecessarily grants these rules to all HAL implementations of the specified service, default/in-process shims or not. This commit adds a new directory, system/sepolicy/vendor, whose rules are concatenated with the device-specific rules at build time. These rules are thus placed into the vendor partition and are not placed into the system/root partition. Test: No change to SELinux policy. Test: Rules placed into vendor directory end up in nonplat* artefacts, but not in plat* artefacts. Bug: 34715716 Change-Id: Iab14aa7a3311ed6d53afff673e5d112428941f1c

Mark all clients of Allocator HAL This change associates all domains which are clients of Allocator HAL with hal_allocator_client and the, required for all HAL client domains, halclientdomain. This enables this commit to remove the now unnecessary hwallocator_use macro because its binder_call(..., hal_allocator_server) is covered by binder_call(hal_allocator_client, hal_allocator_server) added in this commit. Unfortunately apps, except isolated app, are clients of Allocator HAL as well. This makes it hard to use the hal_client_domain(..., hal_allocator) macro because it translates into "typeattribute" which currently does not support being provided with a set of types, such as { appdomain -isolated_app }. As a workaround, hopefully until typeattribute is improved, this commit expresses the necessary association operation in CIL. private/technical_debt.cil introduced by this commit is appended into the platform policy CIL file, thus ensuring that the hack has effect on the final monolithic policy. P. S. This change also removes Allocator HAL access from isolated_app. Isolated app shouldn't have access to this HAL anyway.

Change mapping file name to reflect its platform version. As the platform progresses in the split SELinux world, the platform will need to maintain mapping files back to previous platform versions to maintain backwards compatibility with vendor images which have SELinux policy written based on the older versions. This requires shipping multiple mapping files with the system image so that the right one can be selected. Change the name and location of the mapping file to reflect this. Also add a file to the vendor partition indicating which version is being targeted that the platform can use to determine which mapping file to choose.

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.

Remove BOARD_SEPOLICY_VERS_DIR build variable. The original purpose of BOARD_SEPOLICY_VERS_DIR was to allow the specification of an alternate platform public policy, primarily for testing purposes. This should not be a part of the released platform, since the only public policy and corresponding mapping file construction should be based on the current public platform policy, with compatibility with vendor policy targeting previous versions provided by static mapping files. Its continued presence muddles the generation of mapping files by potentially introducing a situation in which an incorrect mapping file is generated. Remove it.

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.

Split general policy into public and private components. Divide policy into public and private components. This is the first step in splitting the policy creation for platform and non-platform policies. The policy in the public directory will be exported for use in non-platform policy creation. Backwards compatibility with it will be achieved by converting the exported policy into attribute-based policy when included as part of the non-platform policy and a mapping file will be maintained to be included with the platform policy that maps exported attributes of previous versions to the current platform version. Eventually we would like to create a clear interface between the platform and non-platform device components so that the exported policy, and the need for attributes is minimal. For now, almost all types and avrules are left in public. Test: Tested by building policy and running on device. Change-Id: Idef796c9ec169259787c3f9d8f423edf4ce27f8c

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.

Split general policy into public and private components. Divide policy into public and private components. This is the first step in splitting the policy creation for platform and non-platform policies. The policy in the public directory will be exported for use in non-platform policy creation. Backwards compatibility with it will be achieved by converting the exported policy into attribute-based policy when included as part of the non-platform policy and a mapping file will be maintained to be included with the platform policy that maps exported attributes of previous versions to the current platform version. Eventually we would like to create a clear interface between the platform and non-platform device components so that the exported policy, and the need for attributes is minimal. For now, almost all types and avrules are left in public. Test: Tested by building policy and running on device. Change-Id: Idef796c9ec169259787c3f9d8f423edf4ce27f8c

Mark all clients of Allocator HAL This change associates all domains which are clients of Allocator HAL with hal_allocator_client and the, required for all HAL client domains, halclientdomain.

Unfortunately apps, except isolated app, are clients of Allocator HAL as well. This makes it hard to use the hal_client_domain(..., hal_allocator) macro because it translates into "typeattribute" which currently does not support being provided with a set of types, such as { appdomain -isolated_app }. As a workaround, hopefully until typeattribute is improved, this commit expresses the necessary association operation in CIL. private/technical_debt.cil introduced by this commit is appended into the platform policy CIL file, thus ensuring that the hack has effect on the final monolithic policy.

sepolicy: add version_policy tool and version non-platform policy. In order to support platform changes without simultaneous updates from non-platform components, the platform and non-platform policies must be split. In order to provide a guarantee that policy written for non-platform objects continues to provide the same access, all types exposed to non-platform policy are versioned by converting them and the policy using them into attributes. This change performs that split, the subsequent versioning and also generates a mapping file to glue the different policy components together. Test: Device boots and runs.

Test CIL policy when building it Prior to this commit, there was a bug in generated CIL where it wouldn't compile using secilc. The reason was that the build script was stripping out all lines containing "neverallow" from CIL files, accidentally removing lines which were not neverallow statements, such as lmx lines referencing app_neverallows.te. The commit fixes the build script's CIL neverallow filter to filter out only neverallow* statements, as originally intended. Moreover, to catch non-compiling CIL policy earlier in the future, this commit runs secilc on the policy at build time.

Move split sepolicy to correct locations This moves the CIL files comprising the split sepolicy to the directories/partitions based on whether the file is part of platform/system or non-platform/vendor. In particular: * plat_sepolicy.cil is moved to /system/etc/selinux, * nonplat_sepolicy.cil is moved to /vendor/etc/selinux, and * mapping_sepolicy.cil is moved to /vendor/etc/selinux. Test: Device boots, no additional denials. The test is performed both for a device without the CIL files and with the three CIL files.

Device-agnostic policy for vendor image Default HAL implementations are built from the platform tree and get placed into the vendor image. The SELinux rules needed for these HAL implementations to operate thus need to reside on the vendor partition. Up to now, the only place to define such rules in the source tree was the system/sepolicy/public directory. These rules are placed into the vendor partition. Unfortunately, they are also placed into the system/root partition, which thus unnecessarily grants these rules to all HAL implementations of the specified service, default/in-process shims or not. This commit adds a new directory, system/sepolicy/vendor, whose rules are concatenated with the device-specific rules at build time. These rules are thus placed into the vendor partition and are not placed into the system/root partition. Test: No change to SELinux policy. Test: Rules placed into vendor directory end up in nonplat* artefacts, but not in plat* artefacts. Bug: 34715716 Change-Id: Iab14aa7a3311ed6d53afff673e5d112428941f1c

# nonplat_policy.conf - A combination of the non-platform private, vendor and
# the exported platform policy associated with the version the non-platform
# policy targets. This needs attributization and to be combined with the
sepolicy: add version_policy tool and version non-platform policy. In order to support platform changes without simultaneous updates from non-platform components, the platform and non-platform policies must be split. In order to provide a guarantee that policy written for non-platform objects continues to provide the same access, all types exposed to non-platform policy are versioned by converting them and the policy using them into attributes. This change performs that split, the subsequent versioning and also generates a mapping file to glue the different policy components together. Test: Device boots and runs.

Remove BOARD_SEPOLICY_VERS_DIR build variable. The original purpose of BOARD_SEPOLICY_VERS_DIR was to allow the specification of an alternate platform public policy, primarily for testing purposes. This should not be a part of the released platform, since the only public policy and corresponding mapping file construction should be based on the current public platform policy, with compatibility with vendor policy targeting previous versions provided by static mapping files. Its continued presence muddles the generation of mapping files by potentially introducing a situation in which an incorrect mapping file is generated. Remove it.

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 CIL policy when building it Prior to this commit, there was a bug in generated CIL where it wouldn't compile using secilc. The reason was that the build script was stripping out all lines containing "neverallow" from CIL files, accidentally removing lines which were not neverallow statements, such as lmx lines referencing app_neverallows.te. The commit fixes the build script's CIL neverallow filter to filter out only neverallow* statements, as originally intended. Moreover, to catch non-compiling CIL policy earlier in the future, this commit runs secilc on the policy at build time. In particular, it tests that platform policy compiles on its own and that nonplatform + platform + mappig policy compiles as well.

Precompiled kernel policy for on-device use This adds build targets for outputing precompiled kernel policy usable on devices with policy split between system and vendor partitions. On such devices, precompiled policy must reside on the vendor partition. Because such devices support updating these partitions independently of each other, the precompiled policy must reference the system partition's policy against which it was compiled. This enables init to establish whether the precompiled policy is valid for the current combination of system and vendor partitions. The referencing is performed by both the system and vendor partitions including the SHA-256 digest of the system partition's policy (plat_sepolicy.cil).

Precompiled kernel policy for on-device use This adds build targets for outputing precompiled kernel policy usable on devices with policy split between system and vendor partitions. On such devices, precompiled policy must reside on the vendor partition. Because such devices support updating these partitions independently of each other, the precompiled policy must reference the system partition's policy against which it was compiled. This enables init to establish whether the precompiled policy is valid for the current combination of system and vendor partitions. The referencing is performed by both the system and vendor partitions including the SHA-256 digest of the system partition's policy (plat_sepolicy.cil). Only the when the digest is the same on both partitions can the precompiled policy be used. Test: plat_sepolicy.cil.sha256 contains exactly the hex form of the SHA-256 digest of plat_sepolicy.cil Test: plat_sepolicy.cil.sha256 is identical precompiled_sepolicy.plat.sha256.

Change recovery to static platform-only compilation. Recovery is not meant to be versioned in the treble model, but rather provided as part of the platform/framework component and self-sufficient. Simplify its compilation by removing the attribute versioning steps, but maintain device-specific policy, which is currently required for full functionality. Bug: 37240781 Bug: 36783775 Test: recovery boots and is able to select commands. Also tried: reboot system, boot to bootloader, factory reset, sideload, view logs, run graphics test, and power off.

Preserve treble-only flag for CTS neverallows CTS includes general_sepolicy.conf built from this project. CTS then tests this file's neverallow rules against the policy of the device under test. Prior to this commit, neverallow rules which must be enforced only for Treble devices we not included into general_sepolicy.conf. As a result, these rules were not enforced for Treble devices. This commit fixes the issue as follows. Because CTS includes only one policy, the policy now contains also the rules which are only for Treble devices. To enable CTS to distinguish rules needed for all devices from rules needed only on Treble devices, the latter rules are contained in sections delimited with BEGIN_TREBLE_ONLY and END_TREBLE_ONLY comments. This commit also removes the unnecessary sepolicy.general target. This target is not used anywhere and is causing trouble because it is verifying neverallows of the policy meant to be used by CTS. This policy can no longer be verified with checkpolicy without conditionally including or excluding Treble-only neverallows.

Split general policy into public and private components. Divide policy into public and private components. This is the first step in splitting the policy creation for platform and non-platform policies. The policy in the public directory will be exported for use in non-platform policy creation. Backwards compatibility with it will be achieved by converting the exported policy into attribute-based policy when included as part of the non-platform policy and a mapping file will be maintained to be included with the platform policy that maps exported attributes of previous versions to the current platform version. Eventually we would like to create a clear interface between the platform and non-platform device components so that the exported policy, and the need for attributes is minimal. For now, almost all types and avrules are left in public. Test: Tested by building policy and running on device. Change-Id: Idef796c9ec169259787c3f9d8f423edf4ce27f8c

Build the selinux_version file. The selinux_version file is used to perform policy versioning checks by libselinux and SELinuxMMAC. When loading policy a check is first performed to determine if the policy out in /data/security/current should be used to override the base policy shipped with the device. The selinux_version file is used to make that choice. The contents of the file simply contains the BUILD_FINGERPRINT that the policy was built against. A simple string comparison is then performed by libselinux and SELinuxMMAC. Change-Id: I69d9d071743cfd46bb247c98f94a193396f8ebbd Signed-off-by: rpcraig <rpcraig@tycho.ncsc.mil>

This is to make recoveryimage/bootimage targets depend on these artifacts explicitly, which reduces the element of surprise. Moreover, this enables us to move non-recovery artifacts around without affecting recovery artifacts. Test: Clean build, flash, device boots just fine, no new denials.

Build the selinux_version file. The selinux_version file is used to perform policy versioning checks by libselinux and SELinuxMMAC. When loading policy a check is first performed to determine if the policy out in /data/security/current should be used to override the base policy shipped with the device. The selinux_version file is used to make that choice. The contents of the file simply contains the BUILD_FINGERPRINT that the policy was built against. A simple string comparison is then performed by libselinux and SELinuxMMAC. Change-Id: I69d9d071743cfd46bb247c98f94a193396f8ebbd Signed-off-by: rpcraig <rpcraig@tycho.ncsc.mil>

Device-agnostic policy for vendor image Default HAL implementations are built from the platform tree and get placed into the vendor image. The SELinux rules needed for these HAL implementations to operate thus need to reside on the vendor partition. Up to now, the only place to define such rules in the source tree was the system/sepolicy/public directory. These rules are placed into the vendor partition. Unfortunately, they are also placed into the system/root partition, which thus unnecessarily grants these rules to all HAL implementations of the specified service, default/in-process shims or not. This commit adds a new directory, system/sepolicy/vendor, whose rules are concatenated with the device-specific rules at build time. These rules are thus placed into the vendor partition and are not placed into the system/root partition. Test: No change to SELinux policy. Test: Rules placed into vendor directory end up in nonplat* artefacts, but not in plat* artefacts. Bug: 34715716 Change-Id: Iab14aa7a3311ed6d53afff673e5d112428941f1c

Build the selinux_version file. The selinux_version file is used to perform policy versioning checks by libselinux and SELinuxMMAC. When loading policy a check is first performed to determine if the policy out in /data/security/current should be used to override the base policy shipped with the device. The selinux_version file is used to make that choice. The contents of the file simply contains the BUILD_FINGERPRINT that the policy was built against. A simple string comparison is then performed by libselinux and SELinuxMMAC. Change-Id: I69d9d071743cfd46bb247c98f94a193396f8ebbd Signed-off-by: rpcraig <rpcraig@tycho.ncsc.mil>

For other devices these files are placed under /, same as before. This change was previously reverted because it affected the location of property_contexts in recovery. Now that we have separate tagets for recovery (see ec78c377c006040d14d92f5b1a1a52da779f20aa), this change no longer affects is recovery.

Device-agnostic policy for vendor image Default HAL implementations are built from the platform tree and get placed into the vendor image. The SELinux rules needed for these HAL implementations to operate thus need to reside on the vendor partition. Up to now, the only place to define such rules in the source tree was the system/sepolicy/public directory. These rules are placed into the vendor partition. Unfortunately, they are also placed into the system/root partition, which thus unnecessarily grants these rules to all HAL implementations of the specified service, default/in-process shims or not. This commit adds a new directory, system/sepolicy/vendor, whose rules are concatenated with the device-specific rules at build time. These rules are thus placed into the vendor partition and are not placed into the system/root partition. Test: No change to SELinux policy. Test: Rules placed into vendor directory end up in nonplat* artefacts, but not in plat* artefacts. Bug: 34715716 Change-Id: Iab14aa7a3311ed6d53afff673e5d112428941f1c

Targets for artifacts needed by recovery This ensures that SELinux policy artifact needed by recovery at runtime have targets in this build script. This is to make recoveryimage/bootimage targets depend on these artifacts explicitly, which reduces the element of surprise. Moreover, this enables us to move non-recovery artifacts around without affecting recovery artifacts. Test: Clean build, flash, device boots just fine, no new denials. Reboot to recovery, recovery boots just fine, no denials. This was tested on bullhead (non A/B device) and sailfish (A/B device). Bug: 33642277 Change-Id: I3c494d9d7fec5c4f487d38964e572757fcf67f57

Device-agnostic policy for vendor image Default HAL implementations are built from the platform tree and get placed into the vendor image. The SELinux rules needed for these HAL implementations to operate thus need to reside on the vendor partition. Up to now, the only place to define such rules in the source tree was the system/sepolicy/public directory. These rules are placed into the vendor partition. Unfortunately, they are also placed into the system/root partition, which thus unnecessarily grants these rules to all HAL implementations of the specified service, default/in-process shims or not. This commit adds a new directory, system/sepolicy/vendor, whose rules are concatenated with the device-specific rules at build time. These rules are thus placed into the vendor partition and are not placed into the system/root partition. Test: No change to SELinux policy. Test: Rules placed into vendor directory end up in nonplat* artefacts, but not in plat* artefacts. Bug: 34715716 Change-Id: Iab14aa7a3311ed6d53afff673e5d112428941f1c

Make DEFAULT_SYSTEM_DEV_CERTIFICATE available in keys.conf In 9af6f1bd59ee2fb0622db8ff25c4806c5527a0b3, the -d option was dropped from insertkeys.py. This was done to allow an Android distribution to replace the default version of keys.conf distributed in external/sepolicy/keys.conf. keys.conf was modified to reference the publicly known test keys in build/target/product/security. Unfortunately, this broke Google's build of Android. Instead of incorporating our keys directory, we were using the default AOSP keys. As a result, apps were getting assigned to the wrong SELinux domain. (see "Steps to reproduce" below) This change continues to allow others to replace keys.conf, but makes DEFAULT_SYSTEM_DEV_CERTIFICATE available as an environment variable in case the customized version wants to make reference to it. This change also modifies the stock version of keys.conf to use DEFAULT_SYSTEM_DEV_CERTIFICATE, which should be appropriate for most Android distributions. It doesn't make any sense to force each OEM to have a copy of this file. Steps to reproduce. 1) Compile and boot Android. 2) Run the following command: "adb shell ps -Z | grep process.media" Expected: $ adb shell ps -Z | grep process.media u:r:media_app:s0 u0_a5 1332 202 android.process.media Actual: $ adb shell ps -Z | grep process.media u:r:untrusted_app:s0 u0_a5 3617 187 android.process.media Bug: 11327304 Change-Id: Ica24fb25c5f9c0e2f4d181718c757cf372467822

Device-agnostic policy for vendor image Default HAL implementations are built from the platform tree and get placed into the vendor image. The SELinux rules needed for these HAL implementations to operate thus need to reside on the vendor partition. Up to now, the only place to define such rules in the source tree was the system/sepolicy/public directory. These rules are placed into the vendor partition. Unfortunately, they are also placed into the system/root partition, which thus unnecessarily grants these rules to all HAL implementations of the specified service, default/in-process shims or not. This commit adds a new directory, system/sepolicy/vendor, whose rules are concatenated with the device-specific rules at build time. These rules are thus placed into the vendor partition and are not placed into the system/root partition. Test: No change to SELinux policy.

Build the selinux_version file. The selinux_version file is used to perform policy versioning checks by libselinux and SELinuxMMAC. When loading policy a check is first performed to determine if the policy out in /data/security/current should be used to override the base policy shipped with the device. The selinux_version file is used to make that choice. The contents of the file simply contains the BUILD_FINGERPRINT that the policy was built against. A simple string comparison is then performed by libselinux and SELinuxMMAC. Change-Id: I69d9d071743cfd46bb247c98f94a193396f8ebbd Signed-off-by: rpcraig <rpcraig@tycho.ncsc.mil>

Test CIL policy when building it Prior to this commit, there was a bug in generated CIL where it wouldn't compile using secilc. The reason was that the build script was stripping out all lines containing "neverallow" from CIL files, accidentally removing lines which were not neverallow statements, such as lmx lines referencing app_neverallows.te. The commit fixes the build script's CIL neverallow filter to filter out only neverallow* statements, as originally intended. Moreover, to catch non-compiling CIL policy earlier in the future, this commit runs secilc on the policy at build time. In particular, it tests that platform policy compiles on its own and that nonplatform + platform + mappig policy compiles as well.

Precompiled kernel policy for on-device use This adds build targets for outputing precompiled kernel policy usable on devices with policy split between system and vendor partitions. On such devices, precompiled policy must reside on the vendor partition. Because such devices support updating these partitions independently of each other, the precompiled policy must reference the system partition's policy against which it was compiled. This enables init to establish whether the precompiled policy is valid for the current combination of system and vendor partitions. The referencing is performed by both the system and vendor partitions including the SHA-256 digest of the system partition's policy (plat_sepolicy.cil). Only the when the digest is the same on both partitions can the precompiled policy be used. Test: plat_sepolicy.cil.sha256 contains exactly the hex form of the SHA-256 digest of plat_sepolicy.cil Test: plat_sepolicy.cil.sha256 is identical precompiled_sepolicy.plat.sha256.

Mark all clients of Allocator HAL This change associates all domains which are clients of Allocator HAL with hal_allocator_client and the, required for all HAL client domains, halclientdomain. This enables this commit to remove the now unnecessary hwallocator_use macro because its binder_call(..., hal_allocator_server) is covered by binder_call(hal_allocator_client, hal_allocator_server) added in this commit. Unfortunately apps, except isolated app, are clients of Allocator HAL as well. This makes it hard to use the hal_client_domain(..., hal_allocator) macro because it translates into "typeattribute" which currently does not support being provided with a set of types, such as { appdomain -isolated_app }. As a workaround, hopefully until typeattribute is improved, this commit expresses the necessary association operation in CIL. private/technical_debt.cil introduced by this commit is appended into the platform policy CIL file, thus ensuring that the hack has effect on the final monolithic policy. P. S. This change also removes Allocator HAL access from isolated_app. Isolated app shouldn't have access to this HAL anyway.
