To prevent from leaking the seed data.
|
|
|
|
|
| |
Expanding less random data with MT is not needed when it
succeeded.

|
|
|
|
|

The role of this is a so-called "salt" but not "seed", rename to
get rid of confusion with other "seed" of PRNG.

Saves comitters' daily life by avoid #include-ing everything from
internal.h to make each file do so instead. This would significantly
speed up incremental builds.
We take the following inclusion order in this changeset:
1. "ruby/config.h", where _GNU_SOURCE is defined (must be the very
first thing among everything).
2. RUBY_EXTCONF_H if any.
3. Standard C headers, sorted alphabetically.
4. Other system headers, maybe guarded by #ifdef
5. Everything else, sorted alphabetically.
Exceptions are those win32-related headers, which tend not be self-
containing (headers have inclusion order dependencies).

With these macros implemented we can write codes just like we can assume
the compiler being clang. MSC_VERSION_SINCE is defined to implement
those macros, but turned out to be handy for other places. The -fdeclspec
compiler flag is necessary for clang to properly handle __has_declspec().

We can check the function pointer passed to
rb_define_singleton_method like how we do so in rb_define_method.
Doing so revealed many arity mismatches.

* random.c: renamed random_data_type as random_mt_type, and append
"MT" to `wrap_struct_name`, respecting the implementation.

Integer overflow for unsigned types are fully defined in C. They
are not always problematic (but not always OK). These functions
in this changeset intentionally utilizes that behaviour.
Blacklist from UBSAN checks for better output.

An instruction is leaf if it has no rb_funcall inside. In order to
check this property, we introduce stack canary which is a random
number collected at runtime. Stack top is always filled with this
number and checked for stack smashing operations, when VM_CHECK_MODE.

Random.urandom. A quick search seems there are no practical use
of this method than securerandom.rb so I think it's OK to rename
but if there are users of it, this hunk is subject to revert.
* test/ruby/test_rand.rb (TestRand#test_urandom): test for it.
* lib/securerandom.rb (SecureRandom.gen_random): Prefer OS-
provided CSPRNG if available. Otherwise falls back to OpenSSL.
Current preference is:
1. CSPRNG routine that the OS has; one of
- getrandom(2),
- arc4random(3), or
- CryptGenRandom()
2. /dev/urandom device
3. OpenSSL's RAND_bytes(3)
If none of above random number generators are available, you
cannot use this module. An exception is raised that case.

glibc still does not define the SYS_getrandom alias for
__NR_getrandom in the Linux kernel. However, installing
up-to-date Linux kernel headers (linux-libc-dev >= 3.17 package
on Debian) will get the __NR_getrandom syscall number defined
properly without relying on glibc.
This allows users with a modern kernel+headers to use the getrandom
syscall without waiting on glibc support.
