It is used only by `mbedtls_sha512_process()`, and in case `MBEDTLS_SHA512_PROCESS_ALT` is defined, it still cannot be reused because of `static` declaration.
On x32, pointers are only 4-bytes wide and need to be loaded using the "movl"
instruction instead of "movq" to avoid loading garbage into the register.
The MULADDC routines for x86-64 are adjusted to work on x32 as well by getting
gcc to load all the registers for us in advance (and storing them later) by
using better register constraints. The b, c, D and S constraints correspond to
the rbx, rcx, rdi and rsi registers respectively.
On x32 systems, pointers are 4-bytes wide and are therefore stored in %e?x
registers (instead of %r?x registers). These registers must be accessed using
"addl" instead of "addq", however the GNU assembler will acccept the generic
"add" instruction and determine the correct opcode based on the registers
passed to it.
For a start, they don't even compile with Visual Studio due to strcasecmp
being missing. Secondly, on Windows Perl scripts aren't executable and have
to be run using the Perl interpreter directly; thankfully CMake is able to
find cygwin Perl straight away without problems.
The server code parses the client hello extensions even when the
protocol is SSLv3 and this behaviour is non compliant with rfc6101.
Also the server sends extensions in the server hello and omitting
them may prevent interoperability problems.
Running valgrind on: "DTLS client reconnect from same port: reconnect,
nbio" results in timeouts.
New version added that runs only under valgrind. Original only runs when
valgrind is not used
The glibc package recently enabled compressed debug symbols but valgrind doesn't
support them yet.
Results in messages like:
--14923-- WARNING: Serious error when reading debug info
--14923-- When reading debug info from /lib/x86_64-linux-gnu/ld-2.21.so:
--14923-- Ignoring non-Dwarf2/3/4 block in .debug_info
First line has 'error' in it which triggers some of the ssl-opt tests
Commit daf534d from PR #457 breaks the build. This may reintroduce a
clang-analyse warning, but this is the wrong fix for that.
The fix removed a call to mbedtls_ecp_curve_info_from_grp_id() to find
the curve info. This fix adds that back in.
The configuration MBEDTLS_MEMORY_BACKTRACE is intended for debug and
is not necessary for test coverage. Because it causes timing problems
in some tests the configuration has been removed as it's not present in
equivalent tests in the all.sh test script.
In order to reduce debugging time, allows you to only run interesting
tests (by number) from the commandline.
e.g. the command 'tests/ssl-opt.sh -n 246,258' will only run test 246
and 258 (as per the number in the log file names)
