Janos Follath 7c3be6b97e Removing 'if' branch from the fix.
This new error shouldn't be distinguishable from other padding errors.
Updating 'bad' instead of adding a new 'if' branch.

Janos Follath f1225eaffc Add tests for the bug IOTSSL-619.
The main goal with these tests is to test the bug in question and
they are not meant to test the entire PKCS#1 v1.5 behaviour. To
achieve full test coverage, further test cases are needed.

Simon Butcher a91d85e331 Fix for net_usleep() timing selftest on mingw
In mingw32, net_usleep() was failing to sleep for the given period, and was
sleeping in microseconds, not milliseconds. Fix backported from mbed TLS 2.x of
using the Win32 Sleep() API call rather than using the timeout of select().

Manuel Pégourié-Gonnard 20715dc73b Make ar invocation more portable
armar doesn't understand the syntax without dash. OTOH, the syntax with dash
is the only one specified by POSIX, and it's accepted by GNU ar, BSD ar (as
bundled with OS X) and armar, so it looks like the most portable syntax.

Manuel Pégourié-Gonnard cf16b79238 Avoid seemingly-possible overflow
By looking just at that test, it looks like 2 + dn_size could overflow. In
fact that can't happen as that would mean we've read a CA cert of size is too
big to be represented by a size_t.

However, it's best for code to be more obviously free of overflow without
having to reason about the bigger picture.

Manuel Pégourié-Gonnard c05014459e Fix wrong length limit in GCM
See for example page 8 of
http://csrc.nist.gov/publications/nistpubs/800-38D/SP-800-38D.pdf

The previous constant probably came from a typo as it was 2^26 - 2^5 instead
of 2^36 - 2^5. Clearly the intention was to allow for a constant bigger than
2^32 as the ull suffix and cast to uint64_t show.

Manuel Pégourié-Gonnard c4a47e3483 Fix bug checking pathlen on first intermediate
Remove check on the pathLenConstraint value when looking for a parent to the
EE cert, as the constraint is on the number of intermediate certs below the
parent, and that number is always 0 at that point, so the constraint is always
satisfied.

The check was actually off-by-one, which caused valid chains to be rejected
under the following conditions:
- the parent certificate is not a trusted root, and
- it has pathLenConstraint == 0 (max_pathlen == 1 in our representation)

fixes #280

Jonathan Leroy 2744df4f7a cert_write : fix "Destination buffer is too small" error
This commit fixes the `Destination buffer is too small` error returned
by `mbedtls_cert_write` command when the values of `subject_name` or
`issuer_name` parameters exceed 128 characters.

I have increased the size of these varaibles from 128 to 256 characters,
but I don't know if it's the best way to solve this issue...

Fixes #315.

Jonathan Leroy b76e43651e Fix boolean values according to DER specs
In BER encoding, any boolean with a non-zero value is considered as
TRUE. However, DER encoding require a value of 255 (0xFF) for TRUE.

This commit makes `mbedtls_asn1_write_bool` function uses `255` instead
of `1` for BOOLEAN values.

With this fix, boolean values are now reconized by OS X keychain (tested
on OS X 10.11).

Fixes #318.

Manuel Pégourié-Gonnard 5ca3640fa7 Fix other int casts in bounds checking
Not a security issue as here we know the buffer is large enough (unless
something else if badly wrong in the code), and the value cast to int is less
than 2^16 (again, unless issues elsewhere).

Still changing to a more correct check as a matter of principle
