dffc6910b1 Three more -Wshadow fixes. 2016-07-28 11:24:03 -04:00
Nick Mathewson
9fe6fea1cc Fix a huge pile of -Wshadow warnings.
These appeared on some of the Jenkins platforms. Apparently some
GCCs care when you shadow globals, and some don't.

09c25697d7 Add a function to simplify a fraction.
Apparently remembering euclid's algorithm does pay off sooner or later.

fb7f90c181 Tweaks on 19435 fix:
* Raise limit: 16k isn't all that high.
   * Don't log when limit exceded; log later on.
   * Say "over" when we log more than we say we log.
   * Add target version to changes file

1135405c8c Fix a variable-shadowing bug in check_private_dir
We introduded a shadowed variable, thereby causing a log message to
be wrong. Fixes 19578. I believe the bug was introduced by
54d7d31cba in 0.2.2.29-beta.

Fix bug19483: avoid range checks when they are always true
Some compilers are smart enough to work out that comparisons to
LONG_MAX are a no-op on L64.

Improve overflow checks in tv_udiff and tv_mdiff
Validate that tv_usec inputs to tv_udiff and tv_mdiff are in range.

Do internal calculations in tv_udiff and tv_mdiff in 64-bit,
which makes the function less prone to integer overflow,
particularly on platforms where long and time_t are 32-bit,
but tv_sec is 64-bit, like some BSD configurations.

Check every addition and subtraction that could overflow.

Fix an integer overflow bug in the tv_mdiff range check
The temporary second used for rounding can cause overflow,
depending on the order the compiler performs the operations.

94762e37b9 Use the Autoconf macro AC_USE_SYSTEM_EXTENSIONS
The Autoconf macro AC_USE_SYSTEM_EXTENSIONS defines preprocessor macros
which turn on extensions to C and POSIX. The macro also makes it easier
for developers to use the extensions without needing (or forgetting) to
define them manually.

The macro can be safely used because it was introduced in Autoconf 2.60
and Tor requires Autoconf 2.63 and above.

e57f26c135 Have correct_tm set tm_wday as well.
The tm_wday field had been left uninitialized, which was causing
some assertions to fail on Windows unit tests.

a17537a238 Fix an fd leak in check_private_dir().
The fd would leak when the User wasn't recogniezed by
getpwnam(). Since we'd then go on to exit, this wasn't a terribad
leak, but it's still not as nice as no leak at all.

36ad65a7d1 When using open() to make sure we created a dir, close the fd afterwards
Found by coverity. Not in any released Tor. Fixes CID 1355640.

Also, don't check for fd correctness with assert(fd).  You need to
assert (fd >= 0).
