From the release notes:
This release of wolfSSL includes a fix for 1 security vulnerability.
Medium level fix for potential cache attack with a variant of
Bleichenbacher’s attack. Earlier versions of wolfSSL leaked PKCS #1 v1.5
padding information during private key decryption that could lead to a
potential padding oracle attack. It is recommended that users update to the
latest version of wolfSSL if they have RSA cipher suites enabled and have
the potential for malicious software to be ran on the same system that is
performing RSA operations. Users that have only ECC cipher suites enabled
and are not performing RSA PKCS #1 v1.5 Decryption operations are not
vulnerable. Also users with TLS 1.3 only connections are not vulnerable to
this attack. Thanks to Eyal Ronen (Weizmann Institute), Robert Gillham
(University of Adelaide), Daniel Genkin (University of Michigan), Adi Shamir
(Weizmann Institute), David Wong (NCC Group), and Yuval Yarom (University of
Adelaide and Data61) for the report.
The paper for further reading on the attack details can be found at
http://cat.eyalro.net/cat.pdf
Drop now upstreamed patch.

Enable hardware acceleration for ARMv8 targets.
When ARMv8 hardware acceleration is enabled on AArch64 without any
additional flags, the build fails with the following messages:

make[3]: *** [Makefile:3801: wolfcrypt/src/port/arm/src_libwolfssl_la-armv8-aes.lo] Error 1
This is because of some inline assembly in parts of the AES structure
using the "m" constraint.
So lets use the flag -mstrict-align to prevent this error.

[Thomas: restrict the -mstrict-align workaround to AArch64, as ARMv8-A
can also be used in an AArch32 build, and in this case, gcc doesn't
support the -mstrict-align flag]

wolfssl is a library, so it should be installed into staging so other
packages can find the header files / library.

Build on ARMV8 fails when hardware acceleration is enabled:
/tmp/ccmGP5RI.s: Assembler messages:
/tmp/ccmGP5RI.s:532: Error: invalid addressing mode at operand 2 -- `ld1 {v0.2d},[x0,256]'
/tmp/ccmGP5RI.s:568: Error: invalid addressing mode at operand 2 -- `st1 {v0.2d},[x0,256]'
/tmp/ccmGP5RI.s:581: Error: invalid addressing mode at operand 2 -- `ld1 {v0.2d},[x0,256]'
/tmp/ccmGP5RI.s:621: Error: invalid addressing mode at operand 2 -- `st1 {v0.2d},[x0,256]'
So let's disable ARMv8 hardware acceleration for now.

The wolfSSL embedded SSL library is a lightweight and portable
SSL/TLS library.
Tested on Beaglebone Black using a tool called testsuite that
comes with wolfssl source code inside the testsuite/ directory.
To build it, we have to pass --enable-examples in the configure,
and then manually copy the binary to the rootfs. Also, to use
this tool, you will we need to copy the certs/* directory to the
rootfs.
Build-tested with test-pkg script.
