for x86 platforms. Unfortunately, this seems like it is required
if we are going to support ffmpeg. The ffmpeg team decreed that they
require text relocations for x86 (only) and that they would not
fix the fact that android 6.0 makes ffmpeg unusable on x86:

Fix __cxa_atexit run-time regression with many registrations

When an array element is added or removed, make only the relevant page
writable, rather than the entire array. The entire array is still made
writable during recompaction and expansion.

This change fixes most of a large regression in __cxa_atexit runtime
(blueline, taskset 10, performance governor, 100000 registrations,
times are in seconds)

async_safe: don't call libc's socket.

Remove stack address check in cfi_basic test.

This is not actually a property that is guaranteed by the bionic
implementation of CFI shadow. Since the gaps between libraries are not
completely inaccessible, it is possible for a stack mapping to sneak in,
which would cause the callback to register in the test library.

This is not a correctness issue in CFI as the actual __cfi_check
callback will reject such address anyway, at a small CPU cost.

Fix OOB read in DNS resolver

The remote server specifies resplen, the length of the response it
intends to send. anssiz represents the size of the destination buffer.
If the reported resplen is larger than the anssiz, the code correctly
only reads up to anssiz bytes, but returns resplen. so later functions
will access far out of bounds.

The fix ensures that the length of send_vc return does not exceed the
buffer size.

Resolve interface flags using SIOCGIFFLAGS ioctl

Normally, getifaddrs() gets its information about interface flags from
RTM_NEWLINK messages. With the ability for non-system apps to send
RTM_GETLINK messages going away, resolve these flags by performing a
SIOCGIFFLAGS ioctl call instead.

This fixes a bug where the flags were erroneously copied over from an
ifaddrmsg's ifa_flags.

Bug: 161869825
Test: atest bionic-unit-tests-static
Test: Connect to wireless network.
Test: Call getifaddrs() from a non-system app targeting API R+, verify
that the interface flags are correct.
