2018-06-05MdePkg/UefiRuntimeLib: Do not allow to be linked by DXE driverRuiyu Ni1-2/+2
When UefiRuntimeLib links to a DXE driver, its constructor still registers a Virtual Address Change event. The event callback will get called when RT.SetVirtualAddressMap() is called from OS. But when the driver is a DXE driver, the memory occupied by the callback function might be zeroed or used by OS since the BS type memory is free memory when entering to RT phase. The patch reverts commit 97511979b4fdd84cf7cd51e43c22dc03e79bd4f3 "MdePkg/UefiRuntimeLib: Support more module types." It makes sure that DXE driver cannot link to this library.

2018-05-21MdePkg/SmmPeriodicSmiLib: Get Periodic SMI Context More RobustlyRuiyu Ni1-23/+15
The PeriodicSmiDispatchFunction() in SmmPeriodicSmiLib may assert with "Bad CR signature". Currently, the SetActivePeriodicSmiLibraryHandler() function (invoked at the beginning of the PeriodicSmiDispatchFunction() function) attempts to locate the PERIODIC_SMI_LIBRARY_HANDLER_CONTEXT structure pointer for the current periodic SMI from a given EFI_SMM_PERIODIC_TIMER_REGISTER_CONTEXT (RegiserContext) structure pointer (using the CR macro). The RegisterContext structure pointer passed to the PeriodicSmiDispatchFunction() is assumed to point to the same RegisterContext structure address given to the SmmPeriodicTimerDispatch2 protocol Register() API in PeriodicSmiEnable(). However, certain SmmPeriodicTimerDispatch2 implementation may copy the RegisterContext to a local buffer and pass that address as the context to PeriodicSmiDispatchFunction() in which case usage of the CR macro to find the parent structure base fails. The patch uses the LookupPeriodicSmiLibraryHandler() function to find the PERIODIC_SMI_LIBRARY_HANDLER_CONTEXT structure pointer. This works even in this scenario since the DispatchHandle returned from the SmmPeriodicTimerDispatch2 Register() function uniquely identifies that registration.

2018-02-21MdePkg/BaseSafeIntLib: fix undefined behavior in SafeInt64Mult()Laszlo Ersek1-0/+2
If we have to negate UnsignedResult (due to exactly one of Multiplicand and Multiplier being negative), and UnsignedResult is exactly MIN_INT64_MAGNITUDE (value 2^63), then the statement *Result = - ((INT64)UnsignedResult); invokes both implementation-defined behavior and undefined behavior. First, MIN_INT64_MAGNITUDE is not representable as INT64, therefore the result of the (inner) conversion (INT64)MIN_INT64_MAGNITUDE is implementation-defined, or an implementation-defined signal is raised, according to ISO C99 6.3.1.3p3. Second, if we assume that the C language implementation defines the conversion to INT64 simply as reinterpreting the bit pattern 0x8000_0000_0000_0000 as a signed integer in two's complement representation, then the conversion immediately produces the negative value MIN_INT64 (value -(2^63)). In turn, the (outer) negation -(MIN_INT64) invokes undefined behavior, because the mathematical result of the negation, namely 2^63, cannot be represented in an INT64 object. (Not even mentioning the fact that the mathematical result would be incorrect.) In practice, the undefined negation of MIN_INT64 happens to produce an unchanged, valid-looking result on x86, i.e. (-(MIN_INT64)) == MIN_INT64. We can summarize this as the undefined -- effectless -- negation canceling out the botched -- auto-negating -- implementation-defined conversion. Instead of relying on such behavior, dedicate a branch to this situation: assign MIN_INT64 directly. The branch can be triggered e.g. by multiplying (2^62) by (-2).

2018-02-06MdePkg/SafeString: Fix potential out-of-bound memory accessRuiyu Ni1-9/+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.
