* commit '98f7659d7e3a7d75c68a41299f6ee55d7d35c27b':
  Don't fail to run DT_INIT and DT_INIT_ARRAY constructors if a shared library has DT_PREINIT_ARRAY constructors.

Elliott Hughes
8147d3c284 Don't fail to run DT_INIT and DT_INIT_ARRAY constructors if a shared library has DT_PREINIT_ARRAY constructors. 
The GNU dynamic linker silently ignores a DT_PREINIT_ARRAY section
in a shared library. We had ineffectual code that tried to report
an error, which I tried to fix but got wrong --- my version still
wouldn't report the error to the caller, but would prevent us from
continuing to call constructors.

* commit '5f28fde8aeee047a70e344c9da937695dc51a3ba':
  linker: only re-open std* for setuid programs.
 2013-04-25 17:01:41 -07:00
Nick Kralevich
8d3e91d4f8 linker: only re-open std* for setuid programs. 
get_AT_SECURE() was getting called before linker_env_init() had
been called, and returning the default value ("true"). This was
causing us to reopen closed stdin, stdout, and stderr for ALL
processes, not just privileged (setuid) processes.

Calling path:
  - __linker_init
    - soinfo_link_image
      - get_AT_SECURE
    - __linker_init_post_relocation
      - linker_env_init

This change restores the intended behavior of only re-opening
stdin, stdout, and stderr for privileged processes.

* commit '240fb8623b1fe027d0d33a9d4c41d99ceb385b58':

Elliott Hughes
0d787c1fa1 Make abort messages available to debuggerd. 
This adds __libc_fatal, cleans up the internal logging code a bit more,
and switches suitable callers over to __libc_fatal. In addition to logging,
__libc_fatal stashes the message somewhere that the debuggerd signal handler
can find it before calling abort.

In the debuggerd signal handler, we pass this address to debuggerd so that
it can come back with ptrace to read the message and present it to the user.

8f2a5a0b40 Clean up internal libc logging. 
We only need one logging API, and I prefer the one that does no
allocation and is thus safe to use in any context.

Also use O_CLOEXEC when opening the /dev/log files.

Move everything logging-related into one header file.

ca0c11bd82 Use more types than just 'unsigned' in the linker. 
Still chipping away at the situation where every variable in the
linker was of type 'unsigned'. This patch switches counts over to
being size_t and adds an explicit type for init/fini function pointers
and arrays of function pointers.

Also improve logging from CallArray.

Also remove trailing "\n"s from log messages.

42b2c6a5ee Clean up the argc/argv/envp/auxv handling. 
There's now only one place where we deal with this stuff, it only needs to
be parsed once by the dynamic linker (rather than by each recipient), and it's
now easier for us to get hold of auxv data early on.
