9cddb482b4 Revert "Revert "Implement getifaddrs(3)/freeifaddrs(3).""
This reverts commit 76814a8250.

This differs from the original in fixing the GCC -Werror build:

  bionic/libc/bionic/ifaddrs.cpp: In function 'void __handle_netlink_response(ifaddrs**, nlmsghdr*)':
  bionic/libc/bionic/ifaddrs.cpp:113:62: error: use of old-style cast [-Werror=old-style-cast]
       ifinfomsg* ifi = reinterpret_cast<ifinfomsg*>(NLMSG_DATA(hdr));

This appears to be a GCC bug; the GCC command-line correctly uses -isystem,
and manually adding #pragma GCC system_header doesn't help. So just turn the
warning off for GCC for now. We won't need to worry about building with GCC
soon anyway.

7331fe18d7 linker: implement shared namespaces
Shared namespaces clone the list of loaded native
libraries from the caller namespace. This allows
classloaders for bundled apps to share already loaded
libraries with default namespace.

0945ed5cc5 Implement getifaddrs(3)/freeifaddrs(3).
Time to dust off the old libcore implementation from gingerbread and add it
to bionic. Unlike the original, this actually looks at both RTM_NEWLINK and
RTM_NEWADDR.

0b13f29b2c Fix missing parentheses.
The BIONIC_ROUND_UP_POWER_OF_2 macro did not have parentheses around
the whole expression. This lead to the wrong value being computed when
used as part of a mathematical expression such as this:

  value = BIONIC_ROUND_UP_POWER_OF_2(value) - 1;

This only happens on 64 bit abis.

dd586f2ebd sem_timedwait with a null timeout doesn't mean "forever".
It actually means "crash immediately". Well, it's an error. And callers are
much more likely to realize their mistake if we crash immediately rather
than return EINVAL. Historically, glibc has crashed and bionic -- before
the recent changes -- returned EINVAL, so this is a behavior change.

ad33ebead8 Fix bug in dlmalloc's version of calloc.
Under some circumstances, doing a calloc will make sure that the memory
returned will be zero up to the size of the requested size. However, if
there is more usable size than the requested size, that extra part
of the allocation will not be zeroed. This change fixes it so that the
entire usable memory is always zeroed.

585e959849 Generate libc version-script for brillo
Brillo doesn't use the ndk cruft, so we need

tag to mark such symbols in *.map.txt files.

Lazar Trsic
61cf963efe Fix personality test for mips32r6
When personality syscall is executed on mips64, for a 32bit process,
sys_32_personality() is called, which converts PER_LINUX32 -> PER_LINUX.
Change expected value when mips32 is a second architecture.

31951b7f0d Don't verify version scripts on 32-bit Brillo
Brillo doesn't use the ndk cruft, so the same version scripts do not
apply. Until we have brillo-specific version scripts, just disable the
version script check.

b417169d80 Reset access to system properties on reinitialization
Treat subsequent calls to __system_properties_init() as a
reinitialization of system properties and revoke access to prop files
that have been previously mapped but that the process's current context
does not have access to.  Additionally reset the no_access_ flag in
case permissions have loosened and previously unaccessible files can now
be accessed.

This is meant to work around an issue that setcon() does not revoke
mmap() mappings, so we must manually revoke them after a successful
setcon() call.

46e2eadad2 Do not set properties in bionic_systrace
Currently, if the debug.atrace.tags.enableflags property is not found,
it is set to a safe value such that a pointer to this property can be
stored for later access.  This may result in selinux denials because not
all processes write permissions for this property or permission to
connect to the property write socket at all.

Change I6d953c0c281fd72ad3eba8a479fd258023579b5b writes this property to
a safe value upon boot, which greatly decreases the cases in which this
property will not be accessible and removes the need to write it here.
This commit removes this write.
