21df7f90d2 Fix handling of HS msgs in mbedtls_ssl_read if renegotiation unused
Previously, if `MBEDTLS_SSL_RENEGOTIATION` was disabled, incoming handshake
messages in `mbedtls_ssl_read` (expecting application data) lead to the
connection being closed. This commit fixes this, restricting the
`MBEDTLS_SSL_RENEGOTIATION`-guard to the code-paths responsible for accepting
renegotiation requests and aborting renegotiation attempts after too many
unexpected records have been received.

b0f148c0ab Renegotiation: Add tests for SigAlg ext parsing
This commit adds regression tests for the bug when we didn't parse the
Signature Algorithm extension when renegotiating. (By nature, this bug
affected only the server)

The tests check for the fallback hash (SHA1) in the server log to detect
that the Signature Algorithm extension hasn't been parsed at least in
one of the handshakes.

A more direct way of testing is not possible with the current test
framework, since the Signature Algorithm extension is parsed in the
first handshake and any corresponding debug message is present in the
logs.

73a381772b Parse Signature Algorithm ext when renegotiating
Signature algorithm extension was skipped when renegotiation was in
progress, causing the signature algorithm not to be known when
renegotiating, and failing the handshake. Fix removes the renegotiation
step check before parsing the extension.

d98e9e8577 config.pl get: be better behaved
When printing an option's value, print a newline at the end.

When the requested option is missing, fail with status 1 (the usual
convention for "not found") rather than -1 (which has a
system-dependent effect).

01f57e351c config.pl get: don't rewrite config.h; detect write errors
scripts/config.pl would always rewrite config.h if it was reading it.
This commit changes it to not modify the file when only reading is
required, i.e. for the get command.

Also, die if writing config.h fails (e.g. disk full).

of macros with an empty expansion. Support all cases.

efa14e8b0c Reduce number of MPI's used in pk_parse_key_pkcs1_der
As the optional RSA parameters DP, DQ and QP are effectively discarded (they are only considered for their length to
ensure that the key fills the entire buffer), it is not necessary to read them into separate MPI's.

e167fe6a53 Correct pkparse test case to lead to failure for MBEDTLS_RSA_NO_CRT
The test case parses an RSA private key with N=P=Q=D=E=1 and expects a failure from the PK layer. With the weakened
semantics of `mbedtls_rsa_complete`, the latter won't throw an error on that key in case if MBEDTLS_RSA_NO_CRT is
set. This commit modifies the test case to use N=2 which is rejected by `mbedtls_rsa_complete` regardless of whether
MBEDTLS_RSA_NO_CRT is set or not.

7643d4e30c Fix number of loop iterations in mbedtls_deduce_primes
The number of loop iterations per candidate in `mbedtls_deduce_primes` was off
by one. This commit corrects this and removes a toy non-example from the RSA
test suite, as it seems difficult to have the function fail on small values of N
even if D,E are corrupted.

a565f54c4c Introduce new files rsa_internal.[ch] for RSA helper functions
This commit splits off the RSA helper functions into separate headers and
compilation units to have a clearer separation of the public RSA interface,
intended to be used by end-users, and the helper functions which are publicly
provided only for the benefit of designers of alternative RSA implementations.
