9fb48ac257 libc_init_static: apply relro earlier. 
The dynamic linker applies relro before the preinit and init
arrays are executed, so we should be consistent for statically
linked executables.

fdd6dfa863 am 2c5153b0: libc: add getauxval()

2c5153b043 libc: add getauxval() 
Add support for getauxval().  This method allows a program an easy way
to retrieve information from the kernel auxiliary vector, and will
hopefully replace other clumsy ways of accessing this same information.

This particular function was also added to glibc in glibc 2.16.
See the following URLs for more details.

  * http://lwn.net/Articles/519085/
  * http://www.gnu.org/software/libc/manual/html_node/Auxiliary-Vector.html

This change is a prerequisite for bug 7959813.

07564f2d3a add factory property file definition 
This property file is used for properties which are set at device
provisioning time or in the factory. They are never touched by
a software update or factory data reset and typically contain
data specific to the particular unit.

And the only reason I hadn't done that in bionic is because I wanted to behave
the same as glibc.

 2013-01-10 13:30:16 -08:00

a4b2dc016f Add signalfd call to bionic 
Add signalfd() call to bionic.

Adding the signalfd call was done in 3 steps:
- add signalfd4 system call (function name and syscall
  number) to libc/SYSCALLS.TXT
- generate all necessary headers by calling
  libc/tools/gensyscalls.py. This patch is adding
  the generated files since the build system
  does not call gensyscalls.py.
- create the signalfd wrapper in signalfd.cpp and add
  the function prototype to sys/signalfd.h

(cherry-pick of 0c11611c11f4dc1b6d43587b72c3ccbe8c51a51c, modified to
work with older versions of GCC still in use on some branches.)

fb5e5cbdd4 Fix an off-by-one error in the sigset_t function error handling. 
Spotted while running the tests on MIPS, where sigset_t is
actually large enough. The bits in sigset_t are used such that
signal 1 is represented by bit 0, so the range of signals is
actually [1, 8*sizeof(sigset_t)]; it seems clearer to reword
the code in terms of valid bit offsets [0, 8*sizeof(sigset_t)),
which leads to the usual bounds checking idiom.

4fa35d8ae8 Fix <endian.h> and <sys/endian.h>. 
Previously we'd been relying on getting the machine-specific <endian.h>
instead of the top-level <endian.h>, and <sys/endian.h> was basically broken.
Now, with this patch and the previous patch we should have <endian.h>
and <sys/endian.h> behaving the same. This is basically how NetBSD's endian.h
works, and was probably how ours was originally intended to work.

da73f655fc Add argument checking to sigemptyset(3) and friends. 
You could argue that this is hurting people smart enough to have manually
allocated a large-enough sigset_t, but those people are smart enough to
implement their own sigset functions too.

I wonder whether our least unpleasant way out of our self-inflicted 32-bit
cesspool is to have equivalents of _FILE_OFFSET_BITS such as _SIGSET_T_BITS,
so calling code could opt in? You'd have to be careful passing sigset_t
arguments between code compiled with different options.
