2015-07-07MdeModulePkg/PartitionDxe: Fix media probeRonald Cron
The call in ProbeMediaStatus() to the ReadDisk() function of the EFI_DISK_IO_PROTOCOL interface implemented in DiskIoDxe/DiskIo.c crashed in DiskIo2ReadWriteDisk() because of the NULL value of the destination buffer pointer. Pass the address of a buffer in the stack instead of a NULL pointer. In addition to avoiding the crash, that way, the media probe does not depend anymore on the way the EFI_DISK_IO_PROTOCOL implementation deals with a NULL value of the destination buffer pointer as the UEFI specification does not specify the expected behaviour.

2015-01-12MdeModulePkg/PartitionDxe: Fixed El Torito support when the medium is not a ↵Olivier Martin
CDROM El Torito format can be used on different media (eg: USB). A ISO image can be dumped onto a USB mass-storage. These media might not have the same block size as the CDROM media (ie: 2KB). The El Torito code and the specification assumes a LBA 2KB. In addition, the specification says in "12.3.4.4 CD-ROM and DVD-ROM": UEFI code does not assume a fixed block size. I was able to dupliacte the issue by copying a debian ISO on a USB driver.

2013-08-26MdeModulePkg/DiskIoDxe: fix source/destination pointer of overrun transferLaszlo Ersek
DiskIoCreateSubtaskList() may split the transfer into three segments: - a leading segment, called underrun, which is the fractional, trailing subset of the first underlying block, - a middle segment, which is an integral multiple of underlying blocks, - a trailing segment, called overrun, which is the fractional, leading subset of the last underlying block. This is an example read from the /EFI/BOOT/BOOTX64.EFI file, on the RHEL-6.4 installation ISO (debug log enabled with EFI_D_BLKIO). The underlying block size is 2048 bytes (IDE CD-ROM). DiskIo: Create subtasks for task: Offset/BufferSize/Buffer = 0000000000004600/00002000/BD890018 R:Lba/Offset/Length/WorkingBuffer/Buffer = 0000000000000008/00000600/00000200/BD90D000/BD890018 R:Lba/Offset/Length/WorkingBuffer/Buffer = 000000000000000C/00000000/00000600/BD90D000/BD890218 R:Lba/Offset/Length/WorkingBuffer/Buffer = 0000000000000009/00000000/00001800/00000000/BD890218 The first line corresponds to the underrun. The second line corresponds to the overrun. The third line corresponds to the middle segment. In decimal: - task: read 8192 bytes from offset 17920, storing it at BD890018 - underrun: - read block 8 [16384..18432) into the transfer area, - copy 512 bytes from offset 1536 of the transfer area to BD890018 (target buffer offset 0, running total: 512) - middle segment: - read blocks 9, 10, 11 [18432..24576) into the transfer area, - copy 6144 bytes from offset 0 of the transfer area to BD890218 (target buffer offset 512, running total: 6656) - overrun: - read block 12 [24576..26624) into the transfer area, - copy 1536 bytes from offset 0 of the transfer area to BD890218 (!!!) (target buffer offset 512 (!!!), running total 8192) The values marked with (!!!) constitute the bug -- DiskIoCreateSubtaskList() doesn't take the size of the middle segment into account when it calculates the destination (for reads) or source (for writes) pointer for the overrun. This leads to data corruption. When reading, data is copied form the transfer area to the target buffer with CopyMem (Subtask->Buffer, Subtask->WorkingBuffer + Subtask->Offset, Subtask->Length); calls in DiskIo2OnReadWriteComplete() for nonblocking reads, and in DiskIo2ReadWriteDisk() for blocking reads. Therefore it's enough to adjust Subtask->Buffer when it is initialized. (See BD891A18 below.) DiskIo: Create subtasks for task: Offset/BufferSize/Buffer = 0000000000004600/00002000/BD890018 R:Lba/Offset/Length/WorkingBuffer/Buffer = 0000000000000008/00000600/00000200/BD90D000/BD890018 R:Lba/Offset/Length/WorkingBuffer/Buffer = 000000000000000C/00000000/00000600/BD90D000/BD891A18 R:Lba/Offset/Length/WorkingBuffer/Buffer = 0000000000000009/00000000/00001800/00000000/BD890218 The patched call to DiskIoCreateSubtask() is also executed for write requests. The changed Subtask->Buffer initialization fixes the "overrun half writes" in DiskIo2ReadWriteDisk() too: // // A sub task before this one should be a block read operation, causing // the WorkingBuffer filled with the entire one block data. // CopyMem (Subtask->WorkingBuffer + Subtask->Offset, Subtask->Buffer, Subtask->Length); This code doubles for underrun and overrun half-writes. The patch doesn't modify the underrun case. If we're storing the overrun at the beginning of the pre-read last block (which we're going to write out as a full block), then - Subtask->Offset == 0, - Subtask->Length == OverRun, - the first byte *not* accessed in the source area is ((Buffer + UnderRunLength) + BufferSize) + OverRun.

first call to Start()" not to create any child handle if RemainingDeviepath is the End of Device Path Node, per UEFI 2.3. The others changes include: a. Check RemainingDevicePath at beginning of Supported(), make sure it has been verified before Start() is called. b. Check IO protocol firstly rather than EfiDevicePathProtocolGuid, reduce the times entering into Start() function because EfiDevicePathProtocolGuid existed on most of handle. 2. roll back serial drivers not to create child device, if the device speicifed by remainingdevicepath cannot find in the created devices list. git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@9267 6f19259b-4bc3-4df7-8a09-765794883524

2009-07-24Roll back the change in Partition driver. currently we enhance the EHCI ↵eric_tian
driver to guarantee that the EHCI controller get attached to the EHCI controller before the UHCI driver attaches to the UHCI controller. This way can avoid the case happen that UHCI sees the disconnect and EHCI sees the connect event due to the control transfer in shared port. It may cause Partition.Start to be interrupted by Partition.Stop. git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@8991 6f19259b-4bc3-4df7-8a09-765794883524
2009-07-22if Usb mass storage interface returns EFI_DEVICE_ERROR, we should jump out ↵eric_tian
the loop which is used to determine if the current block device supports GPT/Torito/MBR in Partition driver. This way can avoid Partition.start is interrupted by itself Partition.stop(). git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@8977 6f19259b-4bc3-4df7-8a09-765794883524
