[PATCH v16 0/4] MR6423: Implement NtQuerySystemEnvironmentValueEx, NtQuerySystemInformation SystemBootEnvironmentInformation, GetFirmwareType, GetFirmwareEnvironmentVariable*
ntdll: - `NtQuerySystemInformation` `SystemBootEnvironmentInformation` - `NtQuerySystemEnvironmentValueEx`
kernel32: - `GetFirmwareType` - `GetFirmwareEnvironmentVariableExA` - `GetFirmwareEnvironmentVariableExW` - `GetFirmwareEnvironmentVariableA` - `GetFirmwareEnvironmentVariableW`.
The code is needed to check SecureBoot status, security systems and for example to check the licenses of software that can use efi variables. The behavior matches the behavior of Windows 11. And the output is no different on wine and Windows 11.
Example:
```C #include <stdint.h> #include <stdio.h> #include <stdlib.h> #include <string.h> #include <windows.h> #include <winnt.h> #include <winternl.h> #include <winbase.h> #include <shlwapi.h> #include <securitybaseapi.h>

Hi,
It looks like your patch introduced the new failures shown below. Please investigate and fix them before resubmitting your patch. If they are not new, fixing them anyway would help a lot. Otherwise please ask for the known failures list to be updated.
The tests also ran into some preexisting test failures. If you know how to fix them that would be helpful. See the TestBot job for the details:
The full results can be found at: https://testbot.winehq.org/JobDetails.pl?Key=148283

Allocation size is a caller argument, so you'll need to check for allocation failure. Note that now you assume that multibyte size does not exceed twice the character length of a W string. For example for environment strings we use multiplier of 3. Second argument to ntdll_wcstoumbs() is incorrect.

This could use stricter == -1.

I'd rather returned error instead of retrying.

Could you use some existing function for that?

It's possible you can get rid of ret_size.

Again, this should use some existing function.
This could use some basic tests, as already mentioned.

@nsivov This is exactly the correct behavior, in case of interruption by the kernel or blocking of the file, we try to read it again. It is unlikely that we will get stuck in an infinite blocking. I would prefer to keep the current behavior.

@nsivov there is no such thing, here just a 32-bit string is parsed, guid has a different format.

EAGAIN only related to nonblocking reads and file read is not interruptable. You might also look at other usages of read on the Unix side, we certainly don't make a loop for each file read() and don't have to.

@nsivov yes, it can be done, I didn't notice, thanks. I did it automatically because NtQuerySystemEnvironmentValueEx in Windows requires specifying ret_size, otherwise it will return nothing and it works as IN - buffer size and OUT - return data size.

There is already a discussion of this above.

@gofman but I read with `O_RDONLY | O_NONBLOCK`. If it would be better, I can remove O_NONBLOCK and just return an error.

Yes, O_NONBLOCK is not needed and should be removed (even if does nothing for /proc or /sys filesystems).
