lib/mpi/longlong.h: fix building with 32-bit x86

2019-07-17T02:23:21Z

The mpi library contains some rather old inline assembly statements that produce a lot of warnings for 32-bit x86, such as: lib/mpi/mpih-div.c:76:16: error: invalid use of a cast in a inline asm context requiring an l-value: remove the cast or build with -fheinous-gnu-extensions udiv_qrnnd(qp[i], n1, n1, np[i], d); ~~~~~~~~~~~^~~~~~~~~~~~~~~~~~~~~~~~ lib/mpi/longlong.h:423:20: note: expanded from macro 'udiv_qrnnd' : "=a" ((USItype)(q)), \ ~~~~~~~~~~^~ There is no point in doing a type cast for the output of an inline assembler statement, so just remove the cast here, as we have done for other architectures in the past.

lib/mpi: Fix karactx leak in mpi_powm

2019-07-03T14:11:55Z

Sometimes mpi_powm will leak karactx because a memory allocation failure causes a bail-out that skips the freeing of karactx. This patch moves the freeing of karactx to the end of the function like everything else so that it can't be skipped.

lib/mpi: Fix umul_ppmm() for MIPS64r6

2017-12-22T08:39:09Z

Current MIPS64r6 toolchains aren't able to generate efficient DMULU/DMUHU based code for the C implementation of umul_ppmm(), which performs an unsigned 64 x 64 bit multiply and returns the upper and lower 64-bit halves of the 128-bit result. Instead it widens the 64-bit inputs to 128-bits and emits a __multi3 intrinsic call to perform a 128 x 128 multiply. This is both inefficient, and it results in a link error since we don't include __multi3 in MIPS linux. For example commit 90a53e4432b1 ("cfg80211: implement regdb signature checking") merged in v4.15-rc1 recently broke the 64r6_defconfig and 64r6el_defconfig builds by indirectly selecting MPILIB. The same build errors can be reproduced on older kernels by enabling e.g. CRYPTO_RSA: lib/mpi/generic_mpih-mul1.o: In function `mpihelp_mul_1': lib/mpi/generic_mpih-mul1.c:50: undefined reference to `__multi3' lib/mpi/generic_mpih-mul2.o: In function `mpihelp_addmul_1': lib/mpi/generic_mpih-mul2.c:49: undefined reference to `__multi3' lib/mpi/generic_mpih-mul3.o: In function `mpihelp_submul_1': lib/mpi/generic_mpih-mul3.c:49: undefined reference to `__multi3' lib/mpi/mpih-div.o In function `mpihelp_divrem': lib/mpi/mpih-div.c:205: undefined reference to `__multi3' lib/mpi/mpih-div.c:142: undefined reference to `__multi3' Therefore add an efficient MIPS64r6 implementation of umul_ppmm() using inline assembly and the DMULU/DMUHU instructions, to prevent __multi3 calls being emitted.
