Pierre recommended this workaround for 0.4.8rls before.
Avoids "GetVolumeInformation now fails on NFS volume"
This workaround was recurrently applied for all releases
0.4.8, 0.4.9, 0.4.10, 0.4.11, 0.4.12, 0.4.13.
I never got any reply in the regression-ticket and recurrently
applying this over and over again is a waste of time.
So I decided to commit to master today, but will leave
the ticket unresolved, so when a proper fix will arrive in the future,
the existing ticket will remind us to undo this workaround.
Please note that I replaced #if 0 with #if 1
as discussed with Pierre. That's different to the patch in ticket.
which implements the required functionality.
ntdll and ntoskrnl now have a wrapper for this, with SEH.
This protects the function against malformed / bad images,
whilst still being able to use the code in freeldr et al.
Idea from Thomas.
CORE-14857
The code is mostly unchanged. This includes the following changes:
* Move all wine code to crt/wine to keep it separated from our own code
* Add a minimal winternl.h
* Remove the asm macros from wine/config.h
* Include wine/asm.h where required
* Fix the names of the exported functions (GCC uses thiscall now and no wrappers are used anymore)
The autogenerated name has the format:
"ATL:<hexadecimal_digits_of_pointer><NULL-terminator>"
and the number of hex digits in 0xABCD1234 (for 32-bit == 4-byte)
pointers (without the '0x') is 8 == 4*2, and for 64-bit == 8-byte
pointers (e.g. 0xABCDEF0123456789) is 16 == 8*2.
Dynamically check for sys/types.h and pid_t in wine config.h
Use TARGET_xxx defines instead of _X86_ as this is undefined by GCC
Add some sense in include directories management by using interface
libraries
This adds an evil hack to persuade libstdc++, which tries to import __acrt_iob_func from a DLL.
This can only be solved cleanly by adding a GCC-compatible C++ standard library to our tree later.
This fixes the crashes in HvpGetCellMapped on Windows Server 2003 when booting from Freeloader, as mentioned in maharmstone/btrfs#16.
When the bootloader loads the system hive, it cleans the data pertaining to any volatile keys. The Windows bootloader does this by setting SubKeyCounts[Volatile] to 0. After boot, the kernel marks any cell where this is 0 but SubKeyLists[Volatile] isn't HCELL_NIL as dirty, meaning that the sanitized version will then get flushed to the disk.
Because Freeloader sets SubKeyLists[Volatile] to HCELL_NIL straightaway, Windows thinks the cell is clean, and can unload it without flushing. If it then reads it from the disk, it will crash in HvpGetCellMapped due to the stale volatile pointers.
If you break on nt!CmpInitializeSystemHive on Windows and "gu" to the let the function run, you'll see that DirtyVector of the HHIVE has only the first 8 bits set. If you run it using the official bootloader, it'll have a lot more than that.
