Nick Kralevich c76698f24e VectorImpl.cpp: fix benign multiplication overflow
j is a ssize_t, which can go negative. If it goes negative,
the resulting multiplication of mItemSize*j doesn't make
any sense. Since the value is never used, just don't perform
the calculation if j < 0.

Nick Kralevich 1f28698998 libutils: cleanups for -fsanitize=integer
* Hashing functions rely on integer overflow behavior.
Mark those functions as safe.

* abort() if a passed in size_t value is greater than
UINT32_MAX. This can occur on 64 bit builds where size_t
is larger than uint32_t.

* Special case the index lookup for an empty sorted vector.
Without the special case, size() == 0, and size()-1 underflows.

Narayan Kamath 6832a7a4e0 Remove useless refCounting from FileMap.
Nobody ever called acquire() so release() was always
equivalent to delete. Just use delete instead so that
people can use unique_ptr directly (or shared_ptr if
they really want refcounts).

Narayan Kamath 5955a9f5e4 Remove reference to NOT_USING_KLIBC and cygwin.
The reference to NOT_USING_KLIBC appears to be the only one
in our codebase. This change also removes some cygwin specific
retry logic - all other supported platforms in this section
of the code should support mapping at an offset.

Note that i've reversed the sense of the check, we always sysconf
since that's recommended practice.

Elliott Hughes 9d1f515ed1 Fix the WriteStringToFile overload that takes mode/owner/group.
The actual bug is == instead of !=, but the real cause was me trying to be
too clever. This patch switches to much simpler code, and -- since the
intended use of this code is security anyway -- adds logging if anything
goes wrong.

Elliott Hughes f682b4786a Clean up reading and writing in init.
This isn't particularly useful in and of itself, but it does introduce the
first (trivial) unit test, improves the documentation (including details
about how to debug init crashes), and made me aware of how unpleasant the
existing parser is.

I also fixed a bug in passing --- unless you thought the "peboot" and "pm"
commands were features...

* commit '1c77bf4ce5059f3a770418cfa8afed39ee41ab24':
  Fix windows specific behavior of FileMap
2014-10-16 19:12:48 +00:00
Xavier Ducrohet 1a55aa5e34 Fix windows specific behavior of FileMap
The implementation of the FileMap destructor would
close the file, only on Windows, which did not match
the behavior on mac/linux.

This is because calling munmap does not close the file
descriptor. It must be closed separately, before or after
munmap.

On Windows, the file must also be closed manually,
before or after closing the mappingFile.

The change basically removes the closing file from
the windows-specific part of the destructor, to
make behavior more consistent on all platforms
where the caller to FileMap is responsible for closing
its own file (since FileMap receives an opened file).
