Ran into this when using a program that uses CreateFileMapping and then trying to call `std.fs.createFile` on the mapped file. More info can be found here:
https://stackoverflow.com/questions/41844842/when-error-1224-error-user-mapped-file-occurs
Before:
```
error.Unexpected NTSTATUS=0xc0000243
C:\Users\Ryan\Programming\Zig\zig\lib\std\os\windows.zig:138:40: 0x7ff74e957466 in OpenFile (test.exe.obj)
else => return unexpectedStatus(rc),
^
```
After:
```
FAIL (AccessDenied)
C:\Users\Ryan\Programming\Zig\zig\lib\std\os\windows.zig:137:30: 0x7ff7f5b776ea in OpenFile (test.exe.obj)
.USER_MAPPED_FILE => return error.AccessDenied,
^
```
Test coverage was lacking for chdir() on WASI, allowing this to
regress.
This change makes os.chdir() compile again, and improves the test
logic to use our standard CWD support for WASI.
If a parse node is reserved but never set the node remains
uninitialized and can crash tools doing a linear scan of the nodes
(like ZLS) when switching on the tag.
While it is already mentioned on the `items` attributes of the structs, it is
interesting to comment in every method potentially invalidating pointers to items
that they may do so.
- the meaning of packed structs changed in zig 0.10. adjust accordingly.
Use "extern struct" for the cases that directly map to C structs.
- Add new type info kinds, like enum64 and DeclTag
- change the Type enum to use the canonical names from libbpf.
This is more predictable when comparing with external BPF
documentation (than invented synonyms that need to be guessed)
* crypto.core.aes: process 6 block in parallel instead of 8 on aarch64
At least on Apple Silicon, this is slightly faster than 8 blocks.
* AES: add parallel blocks for tigerlake, rocketlake, alderlake, zen3
...instead of hard-coding it to 20.
- This is consistent with the ChaCha implementation
- NaCl and libsodium, that this API is designed to interop with,
also support 8 and 12 round variants. The 12 round variant, in
particular, provides the same security level as the 20 round variant,
but is obviously faster.
- scrypt currently uses its own non optimized version of Salsa, just
because it use 8 rounds instead of 20. This will help remove code
duplication.
No behavior nor public API changes. The Salsa20 and XSalsa20 still
represent the 20-round variant.
If the noise parameter was null, we didn't use any noise at all.
We unconditionally generated random noise (`noise2`) but didn't use it.
Spotted by @cryptocode, thanks!
When a number of bytes to be allocated is so great that alignForward()
is not possible, return `error.OutOfMemory`.
Companion commit to 3f3003097cbf5a6ad9e0dfc29b2cafbe2e35dded.
Instead of making the memory alignment functions more complicated, I
added more API documentation for their existing semantics.

* std.os.uefi: integer backed structs, add tests to catch regressions
device_path_protocol now uses extern structs with align(1) fields because
the transition to integer backed packed struct broke alignment
added comptime asserts that device_path_protocol structs do not violate
alignment and size specifications
Make the test use the minimum length and set MAX_NAME_BYTES to the maximum so that:
- the test will work on any host platform
- *and* the MAX_NAME_BYTES will be able to hold the max file name component on any host platform
