2017-03-20MdeModulePkg/RamDiskDxe: fix C string literal catenation in info messagesLaszlo Ersek
RamDiskDxe installs the RamDiskAcpiCheck() Ready To Boot callback function. If EFI_ACPI_TABLE_PROTOCOL and/or EFI_ACPI_SDT_PROTOCOL are not found, then informational messages are logged, and the RAM disks are not published to the (nonexistent) NFIT table. The logic is fine, but the info messages are not concatenated correctly from multiple string literals -- the second parts are passed as (unused) arguments to DEBUG(). Fix the typos.

2016-05-10MdeModulePkg RamDiskDxe: Fix wrong HII behavior for more than 8 RAM disksHao Wu
The RamDiskDxe driver originally uses a variable-length HII varstore to retrieve the HII checkbox status of each registered RAM disk. However, HII does not support the variable-length varstore feature. Therefore, only the checkbox status for the first 8 RAM disks are tracked for the following definition of HII varstore structure considering the alignment: typedef struct { UINT64 Size; UINT8 RamDiskList[0]; } RAM_DISK_CONFIGURATION; This commit uses the private data of each registered RAM disks to track the HII checkbox status instead to resolve the issue.

There are scenario when the BindingStop service of PartitionDxe driver be re-entered. An example will be ejecting a DVD from a SATA DVDROM and then run "reconnect -r" under shell. In this specific case, part of the calling stack will be: PartitionDriverBindingStop() (PartitionDxe) -> Stop first child handle (PartitionDxe) -> ScsiDiskFlushBlocksEx() (ScsiDiskDxe) -> A media change is detected (ScsiDiskDxe) -> Reinstall of BlockIO(2) protocols (ScsiDiskDxe) -> Entering PartitionDriverBindingStop() again (PartitionDxe) -> Potential risk of referencing already stopped child handle (PartitionDxe) ... The current code has potential issue of referencing of already stopped child handle. This commit adds re-entry handling logic to resolve such issue.

2016-03-29MdeModulePkg DiskIoDxe: Media status check not be done at DiskIo levelHao Wu
Found an issue that file system cannot be started on a DVD when doing the following process: Boot to shell with a DVD inside a SATA DVDROM. Eject the DVD and run "reconnect -r". Put the DVD inside again and run "reconnect -r". The cause is that after executing the second reconnect action, DiskIo immediately returns EFI_NO_MEDIA in function DiskIo2ReadWriteDisk() when checking the media information. However, at this time, the media information does not get updated by the ScsiDisk driver. Therefore, DiskIo driver should left the no media check to ScsiDisk driver. Generally, the media changed and media write protect check should also be left to lower-level device driver. Thus, these two checks in function DiskIo2ReadWriteDisk() are also removed.

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.

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.
