2017-04-13MdeModulePkg/UsbBotPei: Fix undefined behavior in signed left shiftHao Wu
In function PeiUsbReadCapacity(), the following expression: LastBlock = (Data.LastLba3 << 24) | (Data.LastLba2 << 16) | (Data.LastLba1 << 8) | Data.LastLba0; (There is also a similar case in function PeiUsbReadFormattedCapacity().) will involve undefined behavior in signed left shift operations. Since Data.LastLbaX is of type UINT8, they will be promoted to int (32 bits, signed) first, and then perform the left shift operation. According to the C11 spec, Section 6.5.7: 4 The result of E1 << E2 is E1 left-shifted E2 bit positions; vacated bits are filled with zeros. If E1 has an unsigned type, the value of the result is E1 * 2^E2 , reduced modulo one more than the maximum value representable in the result type. If E1 has a signed type and nonnegative value, and E1 * 2^E2 is representable in the result type, then that is the resulting value; otherwise, the behavior is undefined. So if bit 7 of Data.LastLba3 is 1, (Data.LastLba3 << 24) will be out of the range within int type. The undefined behavior of the signed left shift might incur potential issues. This commit will add an explicit UINT32 type cast for Data.LastLba3 to refine the codes.

2017-03-21MdeModulePkg/NvmExpressDxe: Memory leak fix in async code flowSuman Prakash
For async commands, the buffer allocated for Prp list is not getting freed, which will cause memory leak for async read write command. For example testing async command flow with custom application to send multiple read write commands were resulting in decrease of available memory page in memmap, which eventually resulted in system hang. Hence freeing AsyncRequest->MapData, AsyncRequest->MapMeta, AsyncRequest->MapPrpList and AsyncRequest->PrpListHost when async command is completed.

2017-03-06MdeModulePkg: Refine casting expression result to bigger sizeHao Wu
There are cases that the operands of an expression are all with rank less than UINT64/INT64 and the result of the expression is explicitly cast to UINT64/INT64 to fit the target size. An example will be: UINT32 a,b; // a and b can be any unsigned int type with rank less than UINT64, like // UINT8, UINT16, etc. UINT64 c; c = (UINT64) (a + b); Some static code checkers may warn that the expression result might overflow within the rank of "int" (integer promotions) and the result is then cast to a bigger size. The commit refines codes by the following rules: 1). When the expression is possible to overflow the range of unsigned int/ int: c = (UINT64)a + b; 2). When the expression will not overflow within the rank of "int", remove the explicit type casts: c = a + b; 3). When the expression will be cast to pointer of possible greater size: UINT32 a,b; VOID *c; c = (VOID *)(UINTN)(a + b); --> c = (VOID *)((UINTN)a + b); 4). When one side of a comparison expression contains only operands with rank less than UINT32: UINT8 a; UINT16 b; UINTN c; if ((UINTN)(a + b) > c) {...} --> if (((UINT32)a + b) > c) {...} For rule 4), if we remove the 'UINTN' type cast like: if (a + b > c) {...} The VS compiler will complain with warning C4018 (signed/unsigned mismatch, level 3 warning) due to promoting 'a + b' to type 'int'.

2017-03-06MdeModulePkg: Refine type cast for pointer subtractionHao Wu
For pointer subtraction, the result is of type "ptrdiff_t". According to the C11 standard (Committee Draft - April 12, 2011): "When two pointers are subtracted, both shall point to elements of the same array object, or one past the last element of the array object; the result is the difference of the subscripts of the two array elements. The size of the result is implementation-defined, and its type (a signed integer type) is ptrdiff_t defined in the <stddef.h> header. If the result is not representable in an object of that type, the behavior is undefined." In our codes, there are cases that the pointer subtraction is not performed by pointers to elements of the same array object. This might lead to potential issues, since the behavior is undefined according to C11 standard. Also, since the size of type "ptrdiff_t" is implementation-defined. Some static code checkers may warn that the pointer subtraction might underflow first and then being cast to a bigger size. For example: UINT8 *Ptr1, *Ptr2; UINTN PtrDiff; ... PtrDiff = (UINTN) (Ptr1 - Ptr2); The commit will refine the pointer subtraction expressions by casting each pointer to UINTN first and then perform the subtraction: PtrDiff = (UINTN) Ptr1 - (UINTN) Ptr2; Contributed-under: TianoCore Contribution Agreement 1.0 Signed-off-by: Hao Wu <hao.a.wu@intel.com> Acked-by: Laszlo Ersek <lersek@redhat.com> Reviewed-by: Feng Tian <feng.tian@intel.com>

According to AHCI Spec 1.3 GHC.AE bit description: "The implementation of this bit is dependent upon the value of the CAP.SAM bit. If CAP.SAM is '0', then GHC.AE shall be read-write and shall have a reset value of '0'. If CAP.SAM is '1', then AE shall be read-only and shall have a reset value of '1'." Being in AhciMode, for proper operation it is required, that GHC.AE bit is always set, before any other AHCI registers are written to. Current AhciMode implementation, both in AhciReset() and AhciModeInitialization() functions, set GHC.AE bit only depending on 'CAP.SAM == 0' condition, assuming (according to the AHCI spec), that otherwise it has to be set anyway. It may however happen, that even if 'CAP.SAM == 1', GHC.AE requires updating by software. This patch enables in AhciMode setting GHC.AE in case its initial value is '0'. It fixes AHCI support for Marvell Armada 70x0 and 80x0 SoC families. The change is transparent to all other platforms.

According to USB spec, there should have a 10ms delay before this operation after resetting a given port. But in original code, there is a possible path which may have no such 10ms delay: UsbHubResetPort()->UsbHubSetPortFeature()->Stall(20)->UsbHubGetPortSt atus()->XhcPollPortStatusChange()->(if RESET_C bit is set)-> XhcInitializeDeviceSlot()->(if RESET_C bit is set)->Stall(10) So this patch is used to fix above issue.

2016-11-14MdeModulePkg/UsbMass: Revert changes of removing retry logicFeng Tian
This patch is used to revert changes done in commit 17f3e942 bc527fbd75068d2d5752b6af54917487 - "MdeModulePkg/UsbMass: Not retry if usb bot transfer execution fail" It's because Usb Floppy will report DEVICE_ERROR for the first several cmds when it need spin up. so retry logic makes sense.

2016-11-10MdeModulePkg/PciSioSerial: Fix a bug that wrongly produces 2 UARTsRuiyu Ni
When PciSioSerial is firstly started with a non-NULL remaining device path, the UART instance is created using the parameters specified in the remaining device path. Later when the driver is started again on the same UART controller with NULL remaining device path, the correct logic is to directly return SUCCESS instead of current buggy implementation which wrongly produces another UART using the default parameters. The bug causes two UARTs are created when the UART is configured in 57600 baud rate.

2016-11-09MdeModulePkg/Ufs: ensure the DBC field of UTP PRDT is dword-alignedFeng Tian
According to UFS Host Controller Spec(JESD223), the bits 1:0 of this DataByteCount field shall be 11b to indicate Dword granularity. But the size of UFS Request Sense Data Response defined in UFS Spec (JESD220C) is 18 which is not Dword aligned, we would have to round down to the multiple of 4 to fill the DBC field to avoid bring issue on some UFS HCs.
