2025-09-19CryptoPkg/BaseCryptLib: Remove tolower() for unit testsMichael D Kinney1-26/+0
tolower() is always provided by the standard C library. Remove the implementation of tolower() from UnitTestHostCrtWrapper.c that is only used when building host based unit tests. PR https://github.com/tianocore/edk2/pull/11217 attempted to resolve this issue by renaming tolower() to avoid duplicate symbols. This change removes this workaround as well.

2024-11-05CryptoPkg: Increase ScratchMemory buffer for openssl 3.0.15Jorge Ramirez-Ortiz1-1/+1
Openssl 3.0.15 has a larger memory footprint. Updating from EDK 2022.2 (openssl 1.1.j) to 2024.2 (openssl 3.0.15) causes our EFI provisioning application[1] to fail due to an out of memory condition. On inspection, at the time of that fault, 2022.2 had an additional 900 pages. This is why this patch proposes the increase of the ScratchMemory buffer by that same ammount.

2024-06-07CryptoPkg: Fix BaseCryptLib CrtWrapper strncpy and strcatSebastian Witt1-1/+40
Following https://bugzilla.tianocore.org/show_bug.cgi?id=2817 this bug could also apply to strncpy and strcat. For strncpy use count+1 if smaller than MAX_STRING_SIZE. This still restricts the destination size to MAX_STRING_SIZE as before but allows a strncpy when the source is close after destination without triggering the InternalSafeStringNoAsciiStrOverlap check in AsciiStrnCpyS. For strcat use the destination string length + the size of the source string including the terminator as destination size if smaller than MAX_STRING_SIZE. Also move both functions to CrtWrapper.c as they do not return the correct return value. AsciiStrnCpyS and AsciiStrCatS return RETURN_VALUE instead of a char * to the destination buffer.

2024-06-07CryptoPkg: Fix BaseCryptLib CrtWrapper strcpySebastian Witt1-1/+1
strcpy fails when strSource is closer than 4096 bytes after strDest. This is caused by an overlap check in AsciiStrCpyS: // // 5. Copying shall not take place between objects that overlap. // SAFE_STRING_CONSTRAINT_CHECK (InternalSafeStringNoAsciiStrOverlap (Destination, DestMax, (CHAR8 *)Source, SourceLen + 1), RETURN_ACCESS_DENIED); Since DestMax is MAX_STRING_SIZE (0x1000) and with a Source that is in this area behind Destination, AsciiStrCpyS will fail and strcpy will do nothing. When called by CRYPTO_strdup in openssl this leads to uninitialzed memory that gets accessed instead of the copied string.

If the expression passed for "str" has side effects, the behavior may be undefined. In a later patch in this series, we're going to resurrect "inet_pton.c" (originally from the StdLib package), which calls strchr() just like that: strchr((xdigits = xdigits_l), ch) strchr((xdigits = xdigits_u), ch) To enable this kind of function call, turn strchr() into a function.

2017-03-06CryptoPkg: Refine type cast for pointer subtractionHao Wu1-3/+3
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: Qin Long <qin.long@intel.com>

2016-01-26CryptoPkg: Fix function qsort for non 32-bit machinesKaryne Mayer1-2/+2
Although the function qsort receives as an argument a "compare" function which returns an "int", QuickSortWorker (the function used internally by qsort to do its job) receives as an argument a "CompareFunction" which returns an "INTN". In a 32-bit machine, "INTN" is defined as "INT32", which is defined as "int" and everything works well. However, when qsort is compiled for a 64-bit machine, "INTN" is defined as "INT64" and the return values of the compare functions become incompatible ("int" for qsort and "INT64" for QuickSortWorker), causing malfunction. For example, let's assume qsort is being compiled for a 64-bit machine. As stated before, the "compare" function will be returning an "int", and "CompareFunction" will be returning an "INT64". When, for example, the "compare" function (which was passed as an argument to qsort and, then, re-passed as an argument to QuickSortWorker) returns -1 (or 0xffffffff, in a 32-bit integer, its original return type) from inside a call to QuickSortWorker, its return value is interpreted as being an "INT64" value - which turns out to be 4294967295 (or 0x00000000ffffffff, in a 64-bit integer) -, making the function QuickSortWorker to behave unexpectedly. Note that this unexpected (or incorrect) conversion does not happen when casting an "INT32" to an "INT64" directly, but does happen when casting function types. The issue is fixed by changing the return type of SORT_COMPARE (the type of "CompareFunction", used by QuickSortWorker) from "INTN" to "int". This way, both qsort and QuickSortWorker use compatible definitions for their compare functions.

2015-12-07CryptoPkg/BaseCryptLib: make mVirtualAddressChangeEvent STATICArd Biesheuvel1-1/+1
Make mVirtualAddressChangeEvent STATIC to prevent it from conflicting with other variables of the same name that may be defined in other libraries (e.g., MdeModulePkg/Universal/Variable/RuntimeDxe) This also removes the risk of mVirtualAddressChangeEvent being merged with other uninitialized variables with external linkage by toolchains that perform COMMON allocation.

while MonthNo is the month of the year, so tm_mon should be MonthNo-1. Similarly, tm_mday is the day of the month, and DayNo is the number of days since the first day of the month.

To work-around this, we use a function pointer, along with a cast to force the code to think that a 'noreturn' function is being called.
