Current syntax of the fstab in device tree (fstab_dt) assumes the
node name is the mount point, which doesn't allow subdir:
vendor { <== using "vendor/abc" leads to syntax error in device tree
compatible = "android,vendor";
dev = "/dev/block/platform/soc.0/f9824900.sdhci/by-name/vendor";
type = "ext4";
mnt_flags = "ro,barrier=1,inode_readahead_blks=8";
fsmgr_flags = "wait";
};
This CL adds a new field "mnt_point" in the fstab_dt configuration:
vendor_abc {
compatible = "android,vendor_abc";
dev = "/dev/block/platform/soc.0/f9824900.sdhci/by-name/abc";
type = "ext4";
mnt_flags = "ro,barrier=1,inode_readahead_blks=8";
mnt_point = "/vendor/abc"; <== new field
fsmgr_flags = "wait";
};
The new field is optional and will fallback to using node name as mount
point if it is absent.
Note that this CL also sorts fstab_dt by mount point, because
/vendor needs to be mounted first, which contains a directory
/vendor/abc, before /vendor/abc can be mounted.

Currently, we only check if the name of a given node in the trie is a
prefix match and the prefix matches array of the final node. This is
incorrect however, as the prefix matches array of intermediate nodes
may contain the prefix for a given property. This change adds that
check and test cases for this case.

The interface lib has been in VNDK-SP because
android.hardware.graphics.mapper@1.0 was using it. However, since the
dependency has gone [1], there is no need keep it in VNDK-SP. The
VNDK-SP set should be kept as small as possible because libs in VNDK-SP
are subject to double-loading.

When ro.vndk.version has a specific VNDK version in it, use the
llndk.libraries.txt and vndksp.libraries.txt files with the version
suffix in the file names.
If ro.vndk.version is "current" or not set, the version suffix will
not be added.
This is to use a proper VNDK snapshot version configuration for a
vendor patition.

Instead of requiring each process to parse the property contexts files
in libc initialization, this change has property_service parse these
files one into a serialized trie, which the property code in libc can
then directly interpret for mapping property names to their associated
SELinux context.

Currently, whenever a new program starts, libc initializes two data
structures related to properties from the raw property_context files.
There are two problems here,
1) This takes roughly 1.2ms on a trivial program to generate contents
that could otherwise be cached.
2) One of the data structures is a descending list of prefixes, each
of which needs to be checked, whereas a trie would be more
efficient.
This change introduces two libraries,
1) libpropertycontextserializer meant to be used by property_service
to create a serialized trie containing all of the property
contexts.
2) libpropertycontextparser meant to be used by libc's property
functions to parse this serialized trie during property lookup.
This new trie also contains the ability to have exact matches instead
of prefix matches for properties, which was not possible before.

Currently, libBacktraceOffline doesn't try .ARM.exidx if a function
appears in .debug_frame. This make it can't unwind through functions
appear in both .debug_frame and .ARM.exidx, but having dwarf instructions
not accepted by libunwind.
This patch fixes this by trying first .debug_frame then .ARM.exidx on arm.

This still doesn't work yet because libusb doesn't support hotplug on

The process_vm_read function is much faster than ptrace, but sometimes
that will not work on a remote process. Modify the libunwindstack
MemoryRemote object to figure out which one it can use.
Wrote new unit test to verify this checking behavior.

using the default ptrace calls.
Add some benchmarks to libbacktrace to compare the two different methods.
