The TurboSHAKE paper just got published:
https://eprint.iacr.org/2023/342.pdf
and unlike the previous K12 paper, suggests 0x1F instead of 0x01
as the default value for "D".
* Fix SHA3 with streaming
Leftover bytes should be added to the buffer, not to the state.
(or, always to the state; we can and probably should eventually get
rid of the buffer)
Fixes#14851
* Add a test for SHA-3 with streaming
It is becoming increasingly common for distributions to want to enable
PIE for all binaries and zig currently does not provide any way to do
so aside from patching the build.zig.
Man page for posix lists EMFILE, man page for linux ENFILE.
Also posix says "The mmap() function adds an extra reference to the file
associated with the file descriptor fildes which is not removed by a
subsequent close() on that file descriptor. This reference is removed
when there are no more mappings to the file."
It sounds counter-intuitive, that a process limit but no system limit can
be exceeeded.
As far as I understand, fildes is only used for file descriptor backed mmaps.
With this change, `break` and `break :blk` will fill the result location
with `.void_value`, ensuring that the value will be type checked.
The same will happen for a for loop that contains no `break`s in it's body.
Closes https://github.com/ziglang/zig/issues/14686.
Multiple processes can sit waiting for the exclusive lock at the same
time, so we want to recheck whether it needs to be updated whenever
we get an exclusive lock.
This also fixes a race condition between one process truncating the
cache file and another process reading it without atomic locking.
In Linux when interacting with the virtual file system when writing
in invalid value to a file the OS will return errno 22 (INVAL).
Instead of triggering an unreachable, this change now returns a
newly introduced error.InvalidArgument.
In Linux when writing to various files in the virtual file system,
for example /sys/fs/cgroup, if you write an invalid value to a file
you'll get errno 16.
This change allows for these specific cases to be caught instead of
being lumped together in UnexpectedError.
