Since commit 6467de5a8840 ("Randomize z ordinates in scalar
mult when timing resistant") wolfssl requires a RNG for an EC
key when the hardened built option is selected.
wc_ecc_set_rng is only available when built hardened, so there
is no safe way to install the RNG to the key regardless whether
or not wolfssl is compiled hardened.
Always export wc_ecc_set_rng so tools such as hostapd can install
RNG regardless of the built settings for wolfssl.

Biggest fix for this version is CVE-2021-3336, which has already been
applied here. There are a couple of low severity security bug fixes as
well.
Three patches are no longer needed, and were removed; the one remaining
was refreshed.
This tool shows no ABI changes:

This should fix CVE-2021-3336:
DoTls13CertificateVerify in tls13.c in wolfSSL through 4.6.0 does not
cease processing for certain anomalous peer behavior (sending an
ED22519, ED448, ECC, or RSA signature without the corresponding
certificate).
The patch is backported from the upstream wolfssl development branch.

This version fixes a large number of bugs, although no security
vulnerabilities are listed.
Full changelog at:
https://www.wolfssl.com/docs/wolfssl-changelog/
or, as part of the version's README.md:
https://github.com/wolfSSL/wolfssl/blob/v4.6.0-stable/README.md
Due a number of API additions, size increases from 374.7K to 408.8K for
arm_cortex_a9_vfpv3-d16. The ABI does not change from previous version.
Backported patches were removed; remaining patch was refreshed.

This fixes the following security problems:
* In earlier versions of wolfSSL there exists a potential man in the
middle attack on TLS 1.3 clients.
* Denial of service attack on TLS 1.3 servers from repetitively sending
ChangeCipherSpecs messages. (CVE-2020-12457)
* Potential cache timing attacks on public key operations in builds that
are not using SP (single precision). (CVE-2020-15309)
* When using SGX with EC scalar multiplication the possibility of side-
channel attacks are present.
* Leak of private key in the case that PEM format private keys are
bundled in with PEM certificates into a single file.
* During the handshake, clear application_data messages in epoch 0 are
processed and returned to the application.

Many bugs were fixed--2 patches removed here.
This release of wolfSSL includes fixes for 5 security vulnerabilities,
including two CVEs with high/critical base scores:
- potential invalid read with TLS 1.3 PSK, including session tickets
- potential hang with ocspstaping2 (always enabled in openwrt)
- CVE-2019-15651: 1-byte overread when decoding certificate extensions
- CVE-2019-16748: 1-byte overread when checking certificate signatures
- DSA attack to recover DSA private keys

Always build AES-GCM support.
Unnecessary patches were removed.
This includes two vulnerability fixes:
CVE-2019-11873: a potential buffer overflow case with the TLSv1.3 PSK
extension parsing.
CVE-2019-13628 (currently assigned-only): potential leak of nonce sizes
when performing ECDSA signing operations. The leak is considered to be
difficult to exploit but it could potentially be used maliciously to
perform a lattice based timing attack.

Removed options that can't be turned off because we're building with
--enable-stunnel, some of which affect hostapd's Config.in.
Adjusted the title of OCSP option, as OCSP itself can't be turned off,
only the stapling part is selectable.
Mark options turned on when wpad support is selected.
Add building options for TLS 1.0, and TLS 1.3.
Add hardware crypto support, which due to a bug, only works when CCM
support is turned off.
Reorganized option conditionals in Makefile.
Add Eneas U de Queiroz as maintainer.

The AX_AM_JOBSERVER macro shipped with m4/ax_am_jobserver.m4 is broken on
plain POSIX shells due to the use of `let`.
Shells lacking `let` will fail to run the generated m4sh code and end up
invoking "make" with "-jyes" as argument, fialing the build.
Since there is no reason in the first place for some random package to
muck with the make job server settings and since we do not want it to
randomly override "-j" either, simply remove references to this defunct
macro to let the build succeed on platforms which not happen to use bash
as default shell.

This seems to cause a false-positive warning/error

Hardening is enabled by default in libwolfssl at build-time.
However, the `settings.h` header is exported (along with other headers)
for build (via Build/InstallDev).
This looks like a small bug/issue with wolfssl.

This is to eliminate any ambiguity about the cyassl/wolfssl lib.
The rename happened some time ago (~3+ years).
As time goes by, people will start to forget cyassl and
start to get confused about the wolfSSL vs cyassl thing.
It's a good idea to keep up with the times (moving forward).
