[FASTFAT] When dealing with attributes on IRP_MJ_CREATE, filter user input to ensure we have only attributes we can handle.
This applies to files newly created, or for files overwritten where attributes are reset/modified.

[FASTFAT] When overwriting a file with FILE_OVERWRITE*, don't erase previous file attributes, only update them.
Keep erasing them in case the file gets overwritten with FILE_SUPERSEDE.

[FASTFAT] On file overwrite, deny it if file as HIDDEN/SYSTEM flag and caller doesn't set them.

[FASTFAT] Revert bd1e7bf: our VPB swapout implementation in FastFAT is buggy and
leaves volumes in half-(dis)mounted state and thus they get remounted while not
completely dismounted.
This can lead to major breakage and data corruption.
This requires deeper fixes (let's just drop that driver!).

[FASFAT] Enable FAT volume dismount using VPB swapout 2017-12-17 23:29:33 +01:00

[FASTFAT] Add a comment (and an ASSERT) in VfatCreateFile() that shows that my stats code is broken... 2017-12-17 18:25:43 +01:00

[FASTFAT] While closing FCBs on dismount, release from tail to head and not the contrary.
It fixes assertion failure in vfatDestroyFCB() where we would have release parent before child.
This is still not perfect, but less bug prone...

With this commits (and ENABLE_SWAPOUT defined), ReactOS seems to unmount FAT volumes quite nice! :-)
(Tried with fsutil volume dismount X:)

[FASTFAT] Fix FastFAT not returning short name for FAT volumes in FileBothDirectoryInformation case
This is likely due to a copy paste error where long name was copied twice and short never.
Fun fact: this was not affecting FATX volumes
Fun fact2: this was defeating a buffer overflow check and thus was allowing buffer overflow!

[FASTFAT] Finally drop the FileNameInformation class for directories.
It makes no sense for them and shouldn't be implemented.
It's an addendum to 9f3c801.

[FASTFAT] Don't mix FileNameInformation and FileNamesInformation (and support the later).
This commit fixes weird behavior in our FastFAT implementation. It was mixing two classes:
FileNameInformation and FileNamesInformation. It was handling FileNameInformation like
FileNamesInformation and was filling buffer with FILE_NAMES_INFORMATION structure instead
of FILE_NAME_INFORMATION structure (how many things did that break?!).
Also, it wasn't implementing the FileNamesInformation class at all. This is required by
ntdll_winetest:directory which doesn't expect it to fail and thus, attempts to read
never filled in memory.

This commit fixes the winetest crash, and may fix other weird FS behavior.

[FASTFAT] Allow partial returns on directory info query for first entry.
This mimics what MS FastFAT does and fixes (a bit) ntdll_winetest:directory.
It still crashes, but go farther.
