Bence Szépkúti 44bfbe3b95 Update copyright notices to use Linux Foundation guidance
As a result, the copyright of contributors other than Arm is now
acknowledged, and the years of publishing are no longer tracked in the
source files.

Also remove the now-redundant lines declaring that the files are part of
MbedTLS.

Jaeden Amero 548ba2e190 timing: Remove redundant include file
There is no need to include winbase.h, as it will be pulled in by
windows.h as needed.

Fixes #2640

irwir 88eeb4f3f7 Implicit _endthread call: comment changed 2018-10-01 14:33:34 +01:00
irwir 5afc7ba8bf Added spaces after type casts
`(void) TimerContext;` seems more consistent with the current style than ((void) TimerContext);
No objections to changing this if necessary.

Manuel Pégourié-Gonnard 5405962954 Fix alarm(0) failure on mingw32
A new test for mbedtls_timing_alarm(0) was introduced in PR 1136, which also
fixed it on Unix. Apparently test results on MinGW were not checked at that
point, so we missed that this new test was also failing on this platform.

Gilles Peskine ada3ee8b9d Timing self test: shorten redundant tests
We don't need to test multiple delays in a self-test.
Save 5s of busy-wait.

Gilles Peskine 8873bcc4de Timing self test: increased duration
Increase the duration of the self test, otherwise it tends to fail on
a busy machine even with the recently upped tolerance. But run the
loop only once, it's enough for a simple smoke test.

Gilles Peskine 0f59b130a9 Timing self test: increased tolerance
mbedtls_timing_self_test fails annoyingly often when running on a busy
machine such as can be expected of a continous integration system.
Increase the tolerances in the delay test, to reduce the chance of
failures that are only due to missing a deadline on a busy machine.

Gilles Peskine 0827d5c07d Timing self test: print some diagnosis information
Print some not-very-nice-looking but helpful diagnosis information if
the timing selftest fails. Since the failures tend to be due to heavy
system load that's hard to reproduce, this information is necessary to
understand what's going on.

Gilles Peskine d92f0aa3be mbedtls_timing_get_timer: don't use uninitialized memory
mbedtls_timing_get_timer with reset=1 is called both to initialize a
timer object and to reset an already-initialized object. In an
initial call, the content of the data structure is indeterminate, so
the code should not read from it. This could crash if signed overflows
trap, for example.

As a consequence, on reset, we can't return the previously elapsed
time as was previously done on Windows. Return 0 as was done on Unix.

Gilles Peskine a0af95f052 Timing: fix mbedtls_set_alarm(0) on Unix/POSIX
The POSIX/Unix implementation of mbedtls_set_alarm did not set the
mbedtls_timing_alarmed flag when called with 0, which was inconsistent
with what the documentation implied and with the Windows behavior.

Manuel Pégourié-Gonnard 325ce093f9 Give better error messages for semi-portable parts
Previously it was failing with errors about headers not found, which is
suboptimal in terms of clarity. Now give a clean error with pointer to the
documentation.

Do the checks in the .c files rather than check_config.h as it keeps them
closer to the platform-specific implementations.

Manuel Pégourié-Gonnard 91bbfb6fb7 Make timing selftest less sensitive
- allow up to 12.5% security/error margin
- use larger delays
- this avoid the security/error margin being too low

The test used to fail about 1 out of 6 times on some buildbots VMs, but never
failed on the physical machines used for development.

Alfred Klomp b308dd72d9 timing.c: avoid referencing garbage value
Found with Clang's `scan-build` tool.

When get_timer() is called with `reset` set to 1, the value of
t->start.tv_sec is used as a rvalue without being initialized first.
This is relatively harmless because the result of get_timer() is not
used by the callers when called in "reset mode". However, scan-build
prints a warning.

Silence the warning by only calculating the delta on non-reset runs,
returning zero otherwise.
