[UDFS] Revert recent commits and apply PR #360 geometry fixes by Copilot · Pull Request #342 · Zero3K20/reactos

Copilot · 2026-05-01T05:07:35Z

Inspect current UDFS geometry-detection logic in drivers/filesystems/udfs/Include/phys_lib.c and identify HDD vs CD-ROM path differences
Update HDD LastLBA path to use the old HDD-style calculation pattern with DiskGeometry (not CD-ROM logic)
Rebuild to verify no regressions in the modified code path
Run final validation checks

@copilot What about applying PR #312 ?

Applied in commit 7cffc5c9. The changes from PR #312 include:

udffs.h: added //#define BRUTE commented-out toggle
udf_dbg.h: replaced all {NOTHING;} and {} no-op macros with ((void)0) (C-safe, warning-free)
Include/mem_tools.c: same {NOTHING;}/{} → ((void)0) cleanup
udf_info/alloc.c: word-at-a-time bitmap verification in UDFCheckSpaceAllocation_ (32 blocks checked per instruction), advance SearchStart past the just-allocated fragment to avoid re-scanning

The UDFSetBits/UDFClrBits macro rewrite from PR #312 was superseded by the existing UDFChunkedSetBitRange/UDFChunkedClrBitRange implementation already present from PR #283, which uses chunked bitmaps and is more complete. Similarly, the UDFMarkBadSpaceAsUsed bounds-check variant from PR #312 was superseded by the UDFChunkedOrMemory-based implementation from PR #283.

D:\reactos\drivers\filesystems\udfs\udf_info/udf_rel.h(247): error C2061: syntax

...

Fixed in commit c13c99c8. The build errors were all C typedef forward-declaration issues introduced by the C++ → C conversion (PR #304):

struct.h: Added struct FCB; typedef struct FCB FCB; before #include "udf_info/udf_rel.h" so that FCB* is a valid pointer type in C when _UDF_DATALOC_INFO is parsed inside udf_rel.h. The typedef struct FCB FCB; that was already in struct.h arrived too late (after the include).
ecma_167.h: Added missing typedef aliases for ImpUseVolDesc, PartitionDesc, LogicalVolDesc, GenericPartitionMap, LogicalVolIntegrityDesc, and LogicalVolHeaderDesc — fixing the struct.h(662) LogicalVolIntegrityDesc error and pre-empting similar errors in mount.c.
osta_misc.h: Added missing typedef aliases for LogicalVolIntegrityDescImpUse, ImpUseVolDescImpUse, UdfPartitionMap2, VirtualAllocationTable15, VirtualAllocationTable20, and FidADImpUse — fixing equivalent errors in mount.c and udf_info.c.

All other errors in the log (Sys_spec_lib.h, udf_info.h, struct.h lines 680–813) were cascades from the FCB* issue and will disappear with the primary fix.

...

Fixed in commit 6d1a8092. Two categories of errors:

udf_dbg.h(54): warning C4028 — The local DbgPrint forward-declaration used PCH Format (non-const char*), but the SDK declares it with PCSTR Format (const char*). Changed to PCSTR Format to match.
C++ default parameter values — UDFFlushFile__, UDFFlushAFile, UDFFlushADirectory, UDFFlushVolume, UDFFlushIsBreaking, and UDFGetRegParameter all had = 0 default arguments in their declarations, which is not valid C. Removed = 0 from all declarations in udf_info/udf_info.h and protos.h, and updated all 17 call sites across strucsup.c, cleanup.c, create.c, shutdown.c, flush.c, write.c, fscntrl.c, udf_info/mount.c, udf_info/udf_info.c, and udf_info/phys_eject.c to pass an explicit 0.

Fixed in commit 54da39bc. Two issues:

GenericPartitionMap1/GenericDesc undeclared — ecma_167.h was missing typedef aliases for GenericPartitionMap1, GenericPartitionMap2, TerminatingDesc, and GenericDesc. Added them alongside the existing aliases at the end of the header.
relPrevExt, prevExt = NULL (C4047) — This was a C++ comma-expression that only assigned NULL to prevExt (leaving relPrevExt uninitialized) while producing a pointer-vs-integer type warning. Replaced with relPrevExt = 0; prevExt = 0;.

@copilot Vcb->LastLBA = (uint32)(PartitionInfo.PartitionLength.QuadPart >> Vcb->SectorShift)/* + Vcb->FirstLBA*/ - 1; is causing slowdown and the drive isn't being mounted after the commit did the change from what it was before to what I mentioned. Please change the line to use DiskGeometry.

Updated in commit 47d60ea4. I changed the disk-path Vcb->LastLBA calculation in UDFGetBlockSize to use DiskGeometry instead of PartitionInfo.PartitionLength, with explicit 64-bit multiplication and bounds checks before assigning to uint32.

@copilot The current DiskGeometry code being used for HDD mounting should be modified to be like how it was before the changes but with the Ex variant changed to the regular one.

@copilot The current DiskGeometry code being used for HDD mounting should be modified to be like how it was before the changes but with the Ex variant changed to the regular one.

Implemented in commit 1ca061f5. I changed the HDD mount LastLBA block back to the prior style while keeping the EX-to-regular geometry conversion (IOCTL_DISK_GET_DRIVE_GEOMETRY/DISK_GEOMETRY), with only minimal safety handling retained.

Zero3K20 · 2026-05-14T23:01:56Z

@copilot I meant the old line that is as follows:

Vcb->LastLBA = (uint32)(DiskGeometryEx.DiskSize.QuadPart >> Vcb->SectorShift)/* + Vcb->FirstLBA*/ - 1;

It was in phys_lib.cpp at line 837. It should be reverted to that/those line(s) and modified to use DiskGeometry instead of DiskGeometryEx.

Applied in commit 8f703cf6. I reverted the HDD LastLBA calculation to the old (... >> Vcb->SectorShift) - 1 style and adapted it to regular DiskGeometry fields (instead of DiskGeometryEx) in phys_lib.c.
