This should reflect what we actually support, while still being a superset
of what native drivers actually support.
Native driver support varies, but, as the comments document, native drivers
(at least as of windows 10) support only RGB -> RGB, YUV -> RGB, and BC -> RGB
conversions. The actual formats supported are a more limited subset than exposed
(despite that the video cards should be perfectly capable of supporting more
conversions) but erring on the side of overreporting seems …

This MR adds support for creating file mapping objects backed by large pages on Linux, by making the following changes:
## wineserver
* On Linux, `create_temp_file` will first attempt to use memfds as the backing fd. If it fails, it'll return to the current codepath, creating a temporary file in either the server or config directory.
* The created memfd will be sealed against writes, if the caller requesting the appropriate page protection flags.
* This removes the requirement that FDs be …
[View More]only created on filesystems/directories that aren't `noexec`.
* In the server method `create_mapping` , if large pages have been requested by the caller, hold that the calling thread's token holds `SeLockMemoryPrivilege` .
* Additionally, add `SeLockMemoryPrivilege` to the list of privileges enabled for the Administrator.
## `ntdll`
* Add `virtual_get_min_large_page_size` and its exported wrapper `wine_unix_get_min_large_page_size`.
* On Linux, the minimum page size is determined by going through `/sys/kernel/mm/hugepages`. If hugepage support was not detected, `STATUS_NOT_SUPPORTED` is returned instead. On other platforms, the older hard-coded value of 2\*1024\*1024 is returned instead.
* `NtCreateSection` will validate certain parameters if large pages are requested. Specifically, it will return STATUS_INVALID_PARAMETER if the requested mapping is not anonymous/unnamed, or the size is not a multiple of the minimum supported page size.
## `kernelbase`
* `GetLargePageMinimum` will use `wine_unix_get_min_large_page_size`.
## `kernel32/tests`
* Add new test test_large_page_file_mapping, which validates privilege enforcements and parameter validation while creating large pages backed file mapping obejcts. The tests are skipped if `GetLargePageMinimum` returns 0.

I see, if you look at it that way it makes sense to use IID, yeah (I was
thinking of the functions as complete separate entities rather than
interface implementations).
I still think it's slightly better to just pass/store func_info_t as a
container though—it's not just the args but everywhere else we need to
store it (like in ProxyFunction as I mentioned), now it's one less field
to worry about. And besides, if we ever do need to change it at some
point later, it will be much easier without affecting call sites.

Would this proposal be only for `read_more_data` or in the broader scope of any call to `NETCON_set_timeout`?
If it is for the latter, it could be tracked in `netconn_t`. I can add that into a separate merge.

If we can assume that `vtbl->SetOption` is guaranteed to handle its own implementation of each timeout (or fallback to `INET_SetOption`), I could see dropping these cases from `InternetSetOptionW`.

Well, I expect them to behave like JS functions. If it were a JS
function, it would check to see if the object type matches, and then do
its thing. If you think of it like this, it wouldn't make much sense for
it to use another object type's function.
As for Wine prefix, we typically have that already for our own custom
interfaces in mshtml, and even though it's all Wine code, it makes it
clearer for someone unfamiliar to understand that the interface is not
something from Windows—so they can find its documentation/code in Wine
code with grep instead of a Google search, and can freely change them
around, etc.

BTW, is there a reason you renamed `IWineJSDispatchHost` to just `IJSDispatchHost` when it's Wine's own interface? I thought it's better to avoid ambiguity with a native interface, especially if we're to extend it (obviously we can't touch native interfaces), makes it a lot more …
[View More]obvious.
And to add to what I said above, what I meant with "retrieving a potentially different function" is mostly theoretical, because as you said current mshtml likely has only one struct layout per interface. **But** if we were to assume this is not the case (addressing the original concern), then two objects could have same IID but different struct layouts and different functions. In such case, instead of failing, it would call the other function that was looked up, since it matches in IID and DISPID. It won't crash, but I don't think it would be quite correct, either. And it still makes the code simpler anyway.

Actually you don't even need to query IID anymore. Just look up the function by dispid, and then check if it's same func_info_t, that's enough.

Yeah, I forgot to validate it in my branch. In BuiltinFuncCall,
something like this would work:
```c
if(func->hook) {
hres =
IWineJSDispatchHost_QueryInterface(&This->IWineJSDispatchHost_iface,
tid_ids[func->tid], (void**)&unk);
if(FAILED(hres))
return hres;
IUnknown_Release(unk);
hres = func->hook(This, setter ? DISPATCH_PROPERTYPUT :
DISPATCH_PROPERTYGET, dp, ret, ei, caller);
if(hres != S_FALSE)
return hres;
}
```
Alternatively, we can pass around `func_info_t` instead of dispid and
tid, but still look it up like in your branch. We can obtain the dispid
and tid from `func_info_t` so that's all that's needed. I'm not sure if
that's an improvement over my approach, but I think it's definitely a
simplification over yours. What do you think?
BTW for `zoom`, the assignment should fail as it does on native (as the
test does), are you sure it's supposed to be using
`IHTMLCSSStyleDeclaration` which doesn't fail? I mean the test will
simply start failing if it picks `IHTMLCSSStyleDeclaration` because the
assignment does not throw exception anymore (when it should be!).

Exceptions
OverflowException
In a 64-bit process, the value of this instance is too large or too small
to represent as a 32-bit signed integer.
MSDN also has a reference to ToInt32() source:
https://github.com/dotnet/runtime/blob/5535e31a712343a63f5d7d796cd874e563e5…
public int ToInt32()
{
#if TARGET_64BIT
return checked((int)_value);
#else
return (int)_value;
#endif
}
It's not clear why a sign extension may lead to an overflow exception.
This patch fixes the problem, and provides a test case that confirms that
entry.Generation field of a GDI32 object is limited by 127 on a 64-bit
platform, while 32-bit Windows doesn't have such a limitation.

This is an early draft of an implementation of key auto-repeat in wineserver to get some feedback. Some open questions:
1. queue_keyboard_message requires a `current` thread, but we don't get one in timeout callbacks. At the moment I am manually setting `current` to the foreground thread, but I am wondering if that's acceptable or we should explore other ways forward (also see TODO in code).

Also, I would hope that opening and caching the `HKCU\Control Panel\Keyboard` hkey would remove most of the cost of performing this operation (if that's even a concern at all).

Setting the timeout on the socket is quite expensive (requires a wineserver call). Maybe we could store the last set timeout separate from configure timeout and update socket timeout only when they don't match?

It looks better, thanks. In addition to minor comments, please split it. Additional `NETCON_set_timeout` fix is a separate fix from setting/getting options. Maybe also separate `NETCON_set_timeout` for send and receive.

[View More]get_dispex_from_this` is one thing, going through the interface take cares of that. For that part, you could just replace the argument in my branch.
But we should also somehow make sure that the hook is safe to call. By binding function info to the exact object instance, we guarantee that it's safe to call `impl_from_*` from hooks. If you accept any function info as an input, you need to somehow validate that it's safe to call it. Something like moving QI earlier would only partially mitigate that. I'm open to other approaches, but unless I'm missing something, there is no such validation in your current branch.
It seems to me that things like 1ffeaa446613 come from some variation of solution to that problem. Maybe it was needed in earlier version, but it shouldn't be needed with "this" being resolved on jscript side. It's no longer arbitrary when it's used for a `IJSDispatchHost` call. I would suggest to try removing it.

Well yes, a pair does work, but I wasn't passing the IID, only the
DISPID after making sure the object implements the required IID, since I
was delegating to the standard InvokeEx (well, almost), which only has
DISPID. But it was still ambiguous as I explained.
But since we pass the mshtml-internal tid (called iid in args) which is
opaque to jscript, I don't really see why this is better than passing
the `func_info_t` directly? Well IMO passing the pair is already more
complex and requires more lookups, more args, etc, but that's just me.
I haven't analyzed the rest yet, I'll look tomorrow as I have to go now,
but `get_dispex_from_this` is primarily useful for jscript proxies since
they can have arbitrary "this" passed. I was using it here (for legacy
function.call) mostly to introduce it earlier and have less to add on
the proxy patch which was already big enough as it is, but it's not its
main purpose. It was just a "split" attempt.
Are you sure you can get rid of it with your method?

I don't know what you mean by that, a pair like (dispid, iid) uniquely defines a function identity. There is nothing special about dispid except that we already need its lookup implemented, so that seems convenient.

The `ok(ptrold + cntold == file->_ptr + file->_cnt, ...);` test is redundant. You're testing `ptrold` and `cntold` values in earlier tests.
