Un-deprecated __system_property_find_nth.

__system_property_find_nth has been available since the beginning of time,
__system_property_foreach only appeared in 16. So anyone who wants to run
on pre-JellyBean devices would want to use __system_property_find_nth.

George Burgess IV [Wed, 5 Apr 2017 00:34:02 +0000 (17:34 -0700)]
libc: add const-correct string.h overloads

libcxx provides const-correct overloads for a few string.h functions.
These overloads use clang's enable_if attribute, so they're preferred
over our FORTIFY'ed equivalents.

This weakens _FORTIFY_SOURCE=2 when used with some of these functions,
since clang needs to see __pass_object_size in order to pass an accurate
result for __builtin_object_size(s, 1) at a callsite. Since those
functions don't have __pass_object_size on their params, clang can't do
that. This makes LLVM lower the __builtin_object_size calls, which means
we get the same result as __builtin_object_size(s, 0).

We have to provide all of the overloads in Bionic, since enable_if is
only used to disambiguate overloads with (otherwise) the same type. In
other words:

// overload 1
char *strchr(const char *, int s) __attribute__((enable_if(1, "")));
// overload 2
char *strchr(char *, int s);

void foo() {
  char cs[1] = {};
  strchr(static_cast<const char *>(cs), '\0'); // calls overload #1.
  strchr(cs, '\0'); // calls overload #2.
}

Cleanup ANDROID_DNS_MODE and BIONIC_DNSCACHE

For security reasons, when a binary is executed which causes a security
transition (eg, a setuid binary, setgid binary, filesystem capabilities,
or SELinux domain transition), the AT_SECURE flag is set. This causes
certain blacklisted environment variables to be stripped before the
process is executed. The list of blacklisted environment variables is
stored in UNSAFE_VARIABLE_NAMES. Generally speaking, most environment
variables used internally by libc show up in this list.

Add ANDROID_DNS_MODE to the list of unsafe variables.
Similar to RESOLV_HOST_CONF and RES_OPTIONS (which are already
blacklisted), this variable controls how name resolution requests are
handled. Allowing ANDROID_DNS_MODE to be set across a security
boundary could induce resolution failures or otherwise impact
name resolution.

Remove BIONIC_DNSCACHE. This does not appear to be used, and setting
this variable across a security boundary could cause name resolution
problems.

Test: Android compiles and runs with no obvious problems.

Addition of a new system file for time zone data

This file is to replace the time_zones_by_country.xml
file from frameworks/base/core/res/res/xml/

This new file is intended to be updated outside of
an OTA, unlike time_zones_by_country.xml.

The tzlookup.xml file is read by code in libcore, not
frameworks/base.

The format of the file is slightly different from
time_zones_by_country.xml but the information is the
same as the current version. It was generated using
a sed transform and manual coallescing of the
<country> elements / comments:

sed 's/<timezones>$/<timezones>\n  <countryzones>/' frameworks/base/core/res/res/xml/time_zones_by_country.xml \
    | sed 's/<\/timezones>/  <\/countryzones>\n<\/timezones>/' \
    | sed 's/<timezone\( code=\"..\">\)/<country\1\n      <id>/g' \
    | sed 's/<\/timezone>/<\/id>\n    <\/country>/g'

The time_zones_by_country.xml file will be deleted
in a follow up change when the new code is wired into
the code that uses this data.

Test: See associated libcore change that will ensure the file
      is kept in sync with tzdata when applying IANA rules
      changes.

7 years agoRefactor sanitized library on-disk layout - bionic.

Refactor sanitized library on-disk layout - bionic.

This CL changes the linker to point to the newly refactored location
of ASAN-ified libraries on disk.

This supports changes made by the following CLs -
https://android-review.googlesource.com/#/c/359087/
https://android-review.googlesource.com/#/c/359389/

Which refactor the on-disk location as follows:
/data/lib* --> /data/asan/system/lib*
/data/vendor/* --> /data/asan/vendor/*

There are a couple of advantages to this, including better isolation
from other components, and more transparent linker renaming and
SELinux policies.

Bug: 36674745
Test: m -j40 && SANITIZE_TARGET="address" m -j40 and the device
boots. All sanitized libraries are correctly located in /data/asan/*.
