Add SNI support to redbean and improve SSL perf This change makes SSL virtual hosting possible. You can now load multiple certificates for multiple domains and redbean will just figure out which one to use, even if you only have 1 ip address. You can also use a jumbo certificate that lists all your domains in the the subject alternative names. This change also makes performance improvements to MbedTLS. Here are some benchmarks vs. cc1920749eb81f346badaf55fbf79620cb718a55 BEFORE AFTER (microsecs) suite_ssl.com 2512881 191738 13.11x faster suite_pkparse.com 36291 3295 11.01x faster suite_x509parse.com 854669 120293 7.10x faster suite_pkwrite.com 6549 1265 5.18x faster suite_ecdsa.com 53347 18778 2.84x faster suite_pk.com 49051 18717 2.62x faster suite_ecdh.com 19535 9502 2.06x faster suite_shax.com 15848 7965 1.99x faster suite_rsa.com 353257 184828 1.91x faster suite_x509write.com 162646 85733 1.90x faster suite_ecp.com 20503 11050 1.86x faster suite_hmac_drbg.no_reseed.com 19528 11417 1.71x faster suite_hmac_drbg.nopr.com 12460 8010 1.56x faster suite_mpi.com 687124 442661 1.55x faster suite_hmac_drbg.pr.com 11890 7752 1.53x faster There aren't any special tricks to the performance imporvements.

Make C memory safe like Rust This change enables Address Sanitizer systemically w/ `make MODE=dbg`. Our version of Rust's `unsafe` keyword is named `noasan` which is used for two functions that do aligned memory chunking, like `strcpy.c` and we need to fix the tiny DEFLATE code, but that's it everything else is fabulous you can have all the fischer price security blankets you need Best of all is we're now able to use the ASAN data in Blinkenlights to colorize the memory dumps. See the screenshot below of a test program: https://justine.lol/blinkenlights/asan.png Which is operating on float arrays stored on the stack, with red areas indicating poisoned memory, and the green areas indicate valid memory.

Remove garbage collector macro from header (#114) We can put this back the moment someone requests it. Pain-free garbage collection for the C language is pretty cool. All it does is overwrite the return address with a trampoline that calls free(). It's not clear what it should be named if it's made a public API.

Add automatic TMPDIR setup/teardown to GNU Make We now guarantee TMPDIR will be defined on a per build rule basis. It'll be an absolute path. It'll be secure and unique. It'll be rm -rf'd after the last shell script line in your build rule is executed. If $TMPDIR is already defined, then it'll be created as a subdirectory of your $TMPDIR and then replace the variable with the new definition. The Landlock Make repository will be updated with examples shortly after this change which shall be known as Landlock Make 1.1.1. See #530

Make C memory safe like Rust This change enables Address Sanitizer systemically w/ `make MODE=dbg`. Our version of Rust's `unsafe` keyword is named `noasan` which is used for two functions that do aligned memory chunking, like `strcpy.c` and we need to fix the tiny DEFLATE code, but that's it everything else is fabulous you can have all the fischer price security blankets you need Best of all is we're now able to use the ASAN data in Blinkenlights to colorize the memory dumps. See the screenshot below of a test program: https://justine.lol/blinkenlights/asan.png Which is operating on float arrays stored on the stack, with red areas indicating poisoned memory, and the green areas indicate valid memory.

Add SNI support to redbean and improve SSL perf This change makes SSL virtual hosting possible. You can now load multiple certificates for multiple domains and redbean will just figure out which one to use, even if you only have 1 ip address. You can also use a jumbo certificate that lists all your domains in the the subject alternative names. This change also makes performance improvements to MbedTLS.
