* commit '823cff847b3b202b235ddd84650338f07bc61511':
  Implement setjmp cookies on AArch64.
  Implement setjmp cookies on ARM.

7fda8d2aa4 Implement setjmp cookies on ARM. 
Reuse the top bits of _JB_SIGFLAG field previously used to store a
boolean to store a cookie that's validated by [sig]longjmp to make it
harder to use as a ROP gadget. Additionally, encrypt saved registers
with the cookie so that an attacker can't modify a register's value to
a specific value without knowing the cookie.

* commit 'cbd0a15be881abb8ce1feb5b389da2f517a9a4c6':
  Fix the way to get main thread stack start address.
 2015-09-17 02:42:52 +00:00
Mor-sarid, Nitzan
569333293a Fix the way to get main thread stack start address. 
For previous way to get the stack using the [stack] string from
/proc/self/task/<pid>/maps is not enough. On x86/x86_64, if an
alternative signal stack is used while a task switch happens,
the [stack] indicator may no longer be correct.

Instead, stack_start from /proc/self/stat which is always inside
the main stack, is used to find the main stack in /proc/self/maps.

edfc9f63a2 linker: don't pass dlextinfo to dependent loads 
Don't pass the parent load's dlextinfo to dependent loads, since this
causes the linker to try to load the dependencies using the same
addresses/relro/fds/etc as the main library, which is never going to
work. This was how it worked before ae69a95 which broke this.

 2015-08-27 23:24:33 +00:00
Elliott Hughes
adf5c7237d Fix regoff_t for LP32 and _FILE_OFFSET_BITS=64. 
bionic is built without _FILE_OFFSET_BITS=64, so internally regoff_t
was 32-bit on LP32, but code compiled with _FILE_OFFSET_BITS would
expect rm_so and rm_eo in struct regmatch_t to be 64-bit, leading to
confusion.

afdd15456a add fortified implementations of write/pwrite{,64} 
These are just based on the read/pread{,64} implementations with the
function calls and error messages adjusted as appropriate. The only
difference is that the buffer parameters are const.

fed2659869 add fortified implementations of fread/fwrite 
A __size_mul_overflow utility is used to take advantage of the checked
overflow intrinsics in Clang and GCC (>= 5). The fallback for older
compilers is the optimized but less than ideal overflow checking pattern
used in OpenBSD.
