Fixes denial of service attack and buffer overflow against TLS 1.3
servers using session ticket resumption. When built with
--enable-session-ticket and making use of TLS 1.3 server code in
wolfSSL, there is the possibility of a malicious client to craft a
malformed second ClientHello packet that causes the server to crash.
This issue is limited to when using both --enable-session-ticket and TLS
1.3 on the server side. Users with TLS 1.3 servers, and having
--enable-session-ticket, should update to the latest version of wolfSSL.
Thanks to Max at Trail of Bits for the report and "LORIA, INRIA, France"
for research on tlspuffin.

Rename libwolfssl-cpu-crypto to libwolfsslcpu-crypto so that the
regular libwolfssl version comes first when running:
opkg install libwolfssl
Normally, if the package name matches the opkg parameter, that package
is preferred. However, for libraries, the ABI version string is
appended to the package official name, and the short name won't match.
Failing a name match, the candidate packages are sorted in alphabetical
order, and a dash will come before any number. So in order to prefer
the original library, the dash should be removed from the alternative
library.

libwolfssl-cpu-crypto is a variant of libwolfssl with support for
cryptographic CPU instructions on x86_64 and aarch64.
On aarch64, wolfSSL does not perform run-time detection, so the library
will crash when the AES functions are called. A preinst script attempts
to check for support by querying /proc/cpuinfo, if installed in a
running system. When building an image, the script will check the
DISTRIB_TARGET value in /etc/openwrt_release, and will abort
installation if target is bcm27xx.

Disable the usage of target specific CPU crypto instructions by default
to allow the package being shared again. Since WolfSSL does not offer
a stable ABI or a long term support version suitable for OpenWrt release
timeframes, we're forced to frequently update it which is greatly
complicated by the package being nonshared.
People who want or need CPU crypto instruction support can enable it in
menuconfig while building custom images for the few platforms that support
them.

The armvirt target is also used to run OpenWrt in lxc on other targets
like a Raspberry Pi. If we set WOLFSSL_HAS_CPU_CRYPTO by default the
wolfssl binray is only working when the CPU supports the hardware crypto
extension.
Some targets like the Raspberry Pi do not support the ARM CPU crypto
extension, compile wolfssl without it by default. It is still possible
to activate it in custom builds.

Openvpn forces CONFIG_WOLFSSL_HAS_OPENVPN=y. When the phase1 bots build
the now non-shared package, openvpn will not be selected, and WolfSSL
will be built without it. Then phase2 bots have CONFIG_ALL=y, which
will select openvpn and force CONFIG_WOLFSSL_HAS_OPENVPN=y. This
changes the version hash, causing dependency failures, as shared
packages expect the phase2 hash.

libwolfssl-benchmark should NOT be compiled as nonshared but
currently there is a bug where, on buildbot stage2, the package
is recompiled to build libwolfssl-benchmark and the dependency
change to the new libwolfssl version.
Each dependant package will now depend on the new wolfssl package
instead of the one previously on stage1 that has a different package
HASH.

and eventually fixed.

This enables AES & SHA CPU instructions for compatible armv8, and x86_64
architectures. Add this to the hardware acceleration choice, since they
can't be enabled at the same time.
The package was marked non-shared, since the arm CPUs may or may not
have crypto extensions enabled based on licensing; bcm27xx does not
enable them. There is no run-time detection of this for arm.
NOTE:
Should this be backported to a release branch, it must be done shortly
before a new minor release, because the change to nonshared will remove
libwolfssl from the shared packages, but the nonshared are only built in
a subsequent release!

"Alternate certification chains, as oppossed to requiring full chain
validataion. Certificate validation behavior is relaxed, similar to
openssl and browsers. Only the peer certificate must validate to a trusted

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.
