* MdePkg/SafeString: Fix potential out-of-bound memory accessRuiyu Ni2018-02-061-9/+9
| | | | | | | | | | | | | | | | | | | | | | | Today's implementation of [Ascii]StrnCpyS/[Ascii]StrnCatS calls StrnLenS () to get the length of source string but supplies the destination buffer size as max size. It's a bug that may cause out-of-bound memory access. For example: StrnCpyS (Dest[10], 10, "hello", 6) -> StrnLenS ("hello", 10) //< cause out-of bound memory access In a pool guard enabled environment, when using shell to edit an existing file which contains empty line, the page fault is met. The patch fixes the four library functions to avoid such out-of-bound memory access.

* MdePkg/BasePrintLib: Fix incomplete print outputWang, Jian J2018-01-041-2/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is caused by previous patch which tried to fix string over-read, which breaks UEFI menu rendering: the following /------------------------------------------------------------------------------\ | Device Manager | \------------------------------------------------------------------------------/ is rendered as /\ | Device Manager | \/.0 2.00 GHz (the spurious digits are SMBIOS data from the home screen) The problem appears to be that the CHAR16 value of BOXDRAW_HORIZONTAL equals 0x2500, which means that testing ArgumentString[] != '\0' (which tests the low byte only) will yield FALSE and terminate the loop prematurely.

* MdePkg/PrintLib: Fix possible negative value left shiftHao Wu2017-09-291-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | REF: https://bugzilla.tianocore.org/show_bug.cgi?id=702 Within function InternalPrintLibSPrintMarker(), possible left shift of a negative value is found in: "(*(ArgumentString + 1) << 8)" which involves undefined behavior. Since '*(ArgumentString + 1)' is of type CONST CHAR8 (signed), it will be promoted to type int (signed) during the left shift operation. If '*(ArgumentString + 1)' is a negative value, the behavior will be undefined. 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. This commit explicitly cast '*(ArgumentString + 1)' with UINT8 to resolve this issue.

* MdePkg/BaseIoLibIntrinsic: fix SEV (=unrolled) variants of IoWriteFifoXX()Laszlo Ersek2017-09-112-6/+6
| | | | | | | | | | | | | | | | | | | | | | | | | In commit b6d11d7c4678 ("MdePkg: BaseIoLibIntrinsic (IoLib class) library", 2017-04-12), the MOV instructions in the write loops were probably copied from the read loops. However, the operand order was not adjusted. As a result, the IoWriteFifoXX() routines, when invoked in SEV guests, now overwrite the source buffer with value 0x01 / 0x0001 / 0x00000001 -- the SevNoRepIo() function returns value 1 in EAX, in SEV guests --, and write the same value to the target IO port. Fix this by putting the target operand (AL / AX / EAX) first, and the source operand (BYTE / WORD / DWORD [ESI/RSI]) second.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 1) Replace InternalBaseLibIsNodeInList() with InternalBaseLibIsListValid(). - The verification whether Node is within the doubly-linked List is now done by IsNodeInList(). - Whether the list is valid is returned. 2) The comments within InsertHeadList() and InsertTailList() stated that it is checked whether Entry is not part of the doubly-linked list. This was not done as argument 3 of InternalBaseLibIsNodeInList() indicated whether the check is done, not whether to check if the node is or is not in the list. This has been fixed by using IsNodeInList() for the ASSERTs. V2: - Fix IsListEmpty() to ASSERT when the passed list is invalid. - Introduce the VERIFY_IS_NODE_IN_LIST() macro to only verify whether the passed node is part of the list when PcdVerifyNodeInList is TRUE. V3: - Introduce the ASSERT_VERIFY_NODE_IN_VALID_LIST() macro which, depending on the value of PcdVerifyNodeInList, verifies whether SecondEntry is or is not part of the same doubly-linked list as FirstEntry and unconditionally verifies whether the doubly-linked list FirstEntry is part of is valid. This prevents InternalBaseLibIsListValid() from being called twice when a function ASSERTs via the result of IsNodeInList(), as it calls InternalBaseLibIsListValid() already. - Remove the VERIFY_IS_NODE_IN_LIST() macro in favor of ASSERT_VERIFY_NODE_IN_VALID_LIST().

* MdePkg/UefiDevicePathLib: Refine the DevPathFromTextiSCSI protocol parsingJiaxin Wu2017-03-301-1/+8
| | | | | | | | | | | | | | | | | | | | | | For current iSCSI protocol parsing, UINT16 truncation may be happened. Since the Spec already have declaimed that 0 is TCP Protocol and 1+ is reserved, the parsing can be refined as below: if (StrCmp (ProtocolStr, L"TCP") == 0) { ISCSIDevPath->NetworkProtocol = 0; } else { // // Undefined and reserved. // ISCSIDevPath->NetworkProtocol = 1; } Cc: Warner Losh <imp@bsdimp.com> Cc: Ye Ting <ting.ye@intel.com> Cc: Fu Siyuan <siyuan.fu@intel.com> Contributed-under: TianoCore Contribution Agreement 1.0 Signed-off-by: Wu Jiaxin <jiaxin.wu@intel.com> Reviewed-by: Warner Losh <imp@bsdimp.com>
* MdePkg/DevicePathLib: Fix FromText bug for multi-instance devicepathRuiyu Ni2017-03-231-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | UefiDevicePathLibConvertTextToDevicePath correctly detects when it has hit a ',' splicing together multiple paths. However, the code that tries to cope with it: {code} if (IsInstanceEnd) { DeviceNode = (EFI_DEVICE_PATH_PROTOCOL *) AllocatePool ( END_DEVICE_PATH_LENGTH); ASSERT (DeviceNode != NULL); SetDevicePathEndNode (DeviceNode); NewDevicePath = AppendDevicePathNode (DevicePath, DeviceNode); FreePool (DevicePath); FreePool (DeviceNode); DevicePath = NewDevicePath; } {code} causes a problem. The END node that's appended it the node for the entire list. So when the node is appended in AppendDevicePathNode, it winds up disappearing. This leads to the path 'PciRoot(0x0),PciRoot(0x0)' parsing as if 'PciRoot(0x0)/PciRoot(0x0)' were specified. These are two very different things.

* MdePkg/UefiDevicePathLib: Fix the wrong MAC address lengthJiaxin Wu2017-03-151-0/+4
| | | | | | | | | | | | | | | | | | Network interface type should be checked before the conversion between text device path node and MAC device path. Otherwise, the MAC text string can't be converted to the representation of a device node, which leads to the series failure of network HII configuration(e.g. IP, VLAN, HTTP Boot configuration in Network Device List).

* MdePkg: Refine casting expression result to bigger sizeHao Wu2017-03-065-15/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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'.
