This is the same mode used by openssh for private keys. This does not
change the mode of an existing file, so users who need something
different can pre-create the file with their designed permissions or
change them after the fact, and running another process that writes to
the key log will not change it back.
By default, programs built in debug mode that open a https connection
will append secrets to the file specified in the SSLKEYLOGFILE
environment variable to allow protocol debugging by external programs.
This was preventing TLSv1.2 from working in some cases, because servers
are allowed to send multiple handshake messages in the first handshake
record, whereas this inital loop was assuming that it only contained a
server hello.
This is mostly nfc cleanup as I was bisecting the client hello to find
the problematic part, and the only bug fix ended up being
key_share.x25519_kp.public_key ++
key_share.ml_kem768_kp.public_key.toBytes()
to
key_share.ml_kem768_kp.public_key.toBytes() ++
key_share.x25519_kp.public_key)
and the same swap in `KeyShare.exchange` as per some random blog that
says "a hybrid keyshare, constructed by concatenating the public KEM key
with the public X25519 key". I also note that based on the same blog
post, there was a draft version of this method that indeed had these
values swapped, and that used to be supported by this code, but it was
not properly fixed up when this code was updated from the draft spec.
Closes#21747
Note that the removed `error.TlsIllegalParameter` case is still caught
below when it is compared to a fixed-length string, but after checking
the proper protocol version requirement first.
The former prevents recognizing code patterns and turning them into libcalls,
which is what we want for compiler-rt. The latter is meant to be used on call
sites to prevent them from being turned into intrinsics.

* Make it work for thumb and aarch64.
* Clean up std.os.windows.teb() a bit.
I also updated stage1/zig.h since the changes are backwards-compatible and are
necessary due to the std.os.windows changes that call the newly-added functions.
The -lldmingw option affects a lot of logic throughout LLD. We need to pass it
for *-windows-gnu even when we're not actually linking MinGW since we're still
using the MinGW ABI with all that that entails. (One particular problem we would
run into is missing handling of stdcall-decorated symbols for 32-bit x86.) Also,
various other LLD options are sensitive to this option, so it's best to pass it
as early as possible.
Closes#11817.
