libs/wolfssl: disable hardening check in `settings.h` This seems to cause a false-positive warning/error while building `libwebsockets-cyassl`. ``` make[6]: Leaving directory '/home/sandu/work/lede/build_dir/target-x86_64_musl/libwebsockets-cyassl/libwebsockets-2.2.1' make[6]: Entering directory '/home/sandu/work/lede/build_dir/target-x86_64_musl/libwebsockets-cyassl/libwebsockets-2.2.1' [ 2%] Building C object CMakeFiles/websockets.dir/lib/base64-decode.c.o In file included from /home/sandu/work/lede/staging_dir/target-x86_64_musl/usr/include/wolfssl/ssl.h:31:0, from /home/sandu/work/lede/staging_dir/target-x86_64_musl/usr/include/cyassl/ssl.h:33, from /home/sandu/work/lede/staging_dir/target-x86_64_musl/usr/include/cyassl/openssl/ssl.h:30, from /home/sandu/work/lede/build_dir/target-x86_64_musl/libwebsockets-cyassl/libwebsockets-2.2.1/lib/private-libwebsockets.h:256, from /home/sandu/work/lede/build_dir/target-x86_64_musl/libwebsockets-cyassl/libwebsockets-2.2.1/lib/base64-decode.c:43: /home/sandu/work/lede/staging_dir/target-x86_64_musl/usr/include/wolfssl/wolfcrypt/settings.h:1642:14: error: #warning "For timing resistance / side-channel attack prevention consider using harden options" [-Werror=cpp] #warning "For timing resistance / side-channel attack prevention consider using harden options" ``` 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.

wolfssl: bump to 4.1.0-stable 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. Signed-off-by: Eneas U de Queiroz <cotequeiroz@gmail.com>

wolfssl: update to 3.15.7, fix Makefile This includes a fix for a medium-level potential cache attack with a variant of Bleichenbacher’s attack. Patches were refreshed. Increased FP_MAX_BITS to allow 4096-bit RSA keys. Fixed poly1305 build option, and some Makefile updates. Signed-off-by: Eneas U de Queiroz <cotequeiroz@gmail.com>
