2019-04-29gprof: define original mcount APIs inserted by compilerSumit Garg
Simplify gprof implementation via defining original mcount APIs: _mcount (for aarch64) and __gnu_mcount_nc (for arm) inserted by compiler instead of providing them via __utee_mcount API. Also remove weak definitions of mcount API that were earlier mandated by linker script via PROVIDE().

2019-03-15libutee: lessen dependency on mbedtls internalsJens Wiklander
Until now tee_api_arith_mpi.c assumed that for instance TEE_BigIntConvertFromOctetString() wouldn't do a mbedtls_mpi_free(mpi); mbedtls_mpi_init(mpi); sequence on the supplied mpi argument. Doing so replaces the special allocation type MBEDTLS_MPI_ALLOC_TYPE_STATIC with MBEDTLS_MPI_ALLOC_TYPE_MALLOC. This results in the value of the mpi argument isn't propagated further to the dest argument of TEE_BigIntConvertFromOctetString(). With this patch we're instead explicitly copying the value of mbedtls_mpi to a TEE_BigInt when the value should be returned. This patch is also needed when upgrading to mbedtls-2.16 or there will be errors.

2019-03-06core: ignore deprecated TA flags EXEC_DDR and USER_MODEJerome Forissier
Commit 387b0ee39b1b ("core: deprecate TA property flags EXEC_DDR and USER_MODE") removes the requirement for user TAs to set the flags TA_FLAG_EXEC_DDR (bit 0) and TA_FLAG_USER_MODE (bit 1), the rationale being that they are meaningless in the current implementation. The macros are re-defined to be zero to reflect the fact that they have no use. But, instead of ignoring the previous values, the TEE core now requires that bits 0 and 1 must *not* be set. This is a problem because it needlessly breaks backward compatibility. A TA built against OP-TEE 3.0.0 will not work with 3.1.0 or later: E/TC:? 0 tee_ta_init_user_ta_session:1040 Invalid TA flag(s) 0x3 This commit changes the acceptable flags mask (TA_FLAGS_MASK) to include the previous EXEC_DDR and USER_MODE bits, thus restoring backward compatibility.

2019-02-25libutee: TEE_MemCompare(): use constant time algorithmJerome Forissier
TEE_MemCompare() currently calls memcmp() which returns as soon as a difference is found in the compared buffers. The fact that the comparison is not constant time for a given buffer size can reveal information on the buffer content and lead to side-channel attacks. Although the GlobalPlatform TEE Internal Core API specification says nothing about this timing aspect, it is unsafe not to propose a constant time implementation to TAs. A member of the GP specification working group confirmed in an informal discussion. Therefore, replace memcmp() with consttime_memcmp() for constant time comparison. If a TA needs the fastest possible buffer comparison it can call the C library function memcmp() (from <string.h>), which we provide in libutils.

Prior to this patch was _TEE_MathAPI_Init() in lib/libutee/tee_api_arith_mpi.c supplying a data buffer which was only 4 byte aligned while mempool_alloc_pool() requires the alignment of long. This will work in 32-bit mode, but could lead to alignment problem in 64-bit mode. The same problem can happen with lib/libutee/tee_api_arith_mpa.c, but so far it has remained hidden.

2019-01-18mbedtls: TEE_BigIntMul(): use temporaryJerome Forissier
mbedtls_mpi_mul_mpi() checks the allocated size of the output number before starting to multiply the numbers. It makes a conservative guess by requiring the result to be at least as large as the sum of the sizes of the input numbers. For instance, if A fits in one "limb" and B fits in two, then the result is expected to have nblimbs = 3 at least. This is sometimes too restrictive. Consider A = 1 (can be represented with nblimbs == 1 32-bit words) and B = 0x0FFFFFFFFFFFFFFF (fits in a bignum with nblimbs == 2 32-bit words). A * B is equal to B and fits in 2 limbs, but the current code requires 3. This patch fixes the problem by allocating a big enough temporary result.
