d957e96b58 Extend MemtagNoteTest.
Calling free() during system property init results in premature
allocator initialization. This has been fixed with a Scudo change in
https://r.android.com/2853684. This patch extends MemtagNoteTest to
verify that there are no stray PROT_MTE mappings when MTE is not
enabled in the binary.

c10d064b5c Introduce hwasan mode for linker
This mode instructs the linker to search for libraries in hwasan
subdirectories of all library search paths. This is set up to contain a
hwasan-enabled copy of libc, which is needed for HWASan programs to
operate. There are two ways this mode can be enabled:

* for native binaries, by using the linker_hwasan64 symlink as its
  interpreter
* for apps: by setting the LD_HWASAN environment variable in wrap.sh

9705aac89a Fix mte tests to allow auto-upgrade.
The kernel MTE mode auto-upgrade feature (see mte_tcf_preferred) allows
silent auto-upgrade of Async MTE mode to Asymm or Sync depending on the
OS settings. Relax the tests to allow either Sync or Async faults when
requesting Async mode, and only Sync faults when requesting Sync.

Also tighten the MTENote test to check that both system allocator and
prctl are off when MTE is disabled.

badcb38d3c Convert bionic dlext test zips to Android.bp
Use cc_genrules to create the dlext test zips needed by the bionic
tests.  The genrules aren't visible to Make, and so don't work with
the `required` property.  Move all of the dependencies to `data_bins`,
`data_libs` or `data` for helper binaries, shared libraries or
genrule zip files respectively.  The `data*` properties copy the
files into the same directory as a test, respecting the
`bionic-loader-test-libs` relative path specified by each, but
does not put each helper binary in its own subdirectory, so update
the paths in each of the tests.

058eb8fa4e Ensure same order of global group members in all NS's
During "step 1" of find_libraries, the linker finds the transitive
closure of dependencies, in BFS order. As it finds each library, it
adds the library to its primary namespace (so that, if some other
library also depends on it, find_loaded_library_by_soname can find the
library in the process of being loaded).

LD_PRELOAD libraries are automatically marked DF_1_GLOBAL, and any
DF_1_GLOBAL library is added to every linker namespace. Previously,
this secondary namespace registration happened after step 1. The result
is that across different namespaces, the order of libraries could vary.
In general, a namespace's primary members will all appear before
secondary members. This is undesirable for libsigchain.so, which we
want to have appear before any other non-preloaded library.

Instead, when an soinfo is added to its primary namespace, immediately
add it to all the other namespaces, too. This ensures that the order of
soinfo objects is the same across namespaces.

Expand the dl.exec_with_ld_config_file_with_ld_preload and
dl.exec_with_ld_config_file tests to cover the new behavior. Mark
lib1.so DF_1_GLOBAL and use a "foo" symbol to mimic the behavior of a
signal API interposed by (e.g.) libsigchain.so and a ASAN preload.

8035caa311 Enable coverage for libc.
Bug: http://b/157081822

- Disable coverage for libtest_check_rtld_next_from_library to make
dlfcn.rtld_next_from_library to pass.
- The coverage runtime sets an environment variable to prevent
clobbering of the coverage data on disk.  Include that variable as well
when checking `printenv` output.  This is done at runtime by checking
for LLVM_PROFILE_FILE environment variable.
- dl.preinit_system_calls still fails after this change.

Test: bionic tests with libc coverage turned on.

071416b700 Use PROT_NONE on the unused parts of CFI shadow.

This change degrades CFI diagnostics for wild jumps and casts (i.e. when
the target of a CFI check is outside of any known library bounds). This
is acceptable, because CFI does not have much to tell about those cases
anyway. Such bugs will show up as SEGV_ACCERR crashes inside
__cfi_slowpath in libdl.so from now on.

XOM is no longer supported by the build system, so remove these
properties.

6a65ccdf52 Remove mips test workarounds.
The mips/mips64 targets were never able to pass these tests, and the
supported architectures don't need any of these workarounds.

22fa3dde07 Ignore symbols of imported libs' dependencies
When a library is present in a namespace via the secondary_namespaces
list (i.e. the executable, LD_PRELOAD, DF_1_GLOBAL, or
android_create_namespace inheritance), then we want to search that
library's symbols, but not the symbols of its dependencies. Otherwise,
we want to search the dependencies to handle cross-NS dependency.

6dd1f587c8 Test all four supported relocation encodings.
Test (a) that we can load the library, but also (b) that readelf thinks
it contains the relocation encoding we were expecting. Do this for all
four of RELR, ANDROID_RELR, relocation packer, and the original ELF
relocation encoding.

6663f5525d Modernize SHT_RELR support.
Until now we've only supported RELR with our own OS-private-use
constants. Add support for the official numbers (while maintaining
support for the historical numbers).

Add tests to ensure we continue to support both indefinitely.

We can't yet flip the build system over to using the official constants
because the old GNU binutils objcopy we still use in most cases (for the
mini-debug section) only supports the historical constants.
