Thanks to elichai2 who noted that the literal '1' is a signed integer, and that shifting a signed 32-bit integer by 31 bits causes an overflow and yields undefined behaviour. While 'scalar_low_impl''s 'secp256k1_scalar_cadd_bit' is only used for testing purposes and currently the 'bit' parameter is only 0 or 1, it is better to avoid undefined behaviour in case the used domain of 'secp256k1_scalar_cadd_bit' expands. 94ae7cb Moved a dereference so the null check will be before the dereferencing 2cb73b1 scalar_impl.h: fix includes fa33017 Merge dashpay#634: Add a descriptive comment for secp256k1_ecmult_const. ee9e68c Add a descriptive comment for secp256k1_ecmult_const. d0d738d Merge dashpay#631: typo in comment for secp256k1_ec_pubkey_tweak_mul () 6914c25 typo in comment for secp256k1_ec_pubkey_tweak_mul () e541a90 Merge dashpay#629: Avoid calling _is_zero when _set_b32 fails. f34b0c3 Merge dashpay#630: Note intention of timing sidechannel freeness. 8d1563b Note intention of timing sidechannel freeness. 1669bb2 Merge dashpay#628: Fix ability to compile tests without -DVERIFY. ecc94ab Merge dashpay#627: Guard memcmp in tests against mixed size inputs. 544435f Merge dashpay#578: Avoid implementation-defined and undefined behavior when dealing with sizes 143dc6e Merge dashpay#595: Allow to use external default callbacks e49f799 Add missing #(un)defines to base-config.h 77defd2 Add secp256k1_ prefix to default callback functions 908bdce Include stdio.h and stdlib.h explicitly in secp256k1.c 5db782e Allow usage of external default callbacks 6095a86 Replace CHECKs for no_precomp ctx by ARG_CHECKs without a return cd473e0 Avoid calling secp256k1_*_is_zero when secp256k1_*_set_b32 fails. 6c36de7 Merge dashpay#600: scratch space: use single allocation 98836b1 scratch: replace frames with "checkpoint" system 7623cf2 scratch: save a couple bytes of unnecessarily-allocated memory a7a164f scratch: rename `max_size` to `size`, document that extra will actually be allocated 5a4bc0b scratch: unify allocations c2b028a scratch space: thread `error_callback` into all scratch space functions 0be1a4a scratch: add magic bytes to beginning of structure 92a48a7 scratch space: use single allocation 40839e2 Merge dashpay#592: Use trivial algorithm in ecmult_multi if scratch space is small dcf3920 Fix ability to compile tests without -DVERIFY. a484e00 Merge dashpay#566: Enable context creation in preallocated memory 0522caa Explain caller's obligations for preallocated memory 238305f Move _preallocated functions to separate header 695feb6 Export _preallocated functions 814cc78 Add tests for contexts in preallocated memory ba12dd0 Check arguments of _preallocated functions 5feadde Support cloning a context into preallocated memory c4fd5da Switch to a single malloc call ef020de Add size constants for preallocated memory 1bf7c05 Prepare for manual memory management in preallocated memory 248bffb Guard memcmp in tests against mixed size inputs. 36698dc Merge dashpay#596: Make WINDOW_G configurable a61a93f Clean up ./configure help strings 2842dc5 Make WINDOW_G configurable 1a02d6c Merge dashpay#626: Revert "Merge dashpay#620: Install headers automatically" 662918c Revert "Merge dashpay#620: Install headers automatically" 14c7dbd Simplify control flow in DER parsing ec8f20b Avoid out-of-bound pointers and integer overflows in size comparisons 01ee1b3 Parse DER-enconded length into a size_t instead of an int 912680e Merge dashpay#561: Respect LDFLAGS and #undef STATIC_PRECOMPUTATION if using basic config 91fae3a Merge dashpay#620: Install headers automatically 5df77a0 Merge dashpay#533: Make sure we're not using an uninitialized variable in secp256k1_wnaf_const(...) 975e51e Merge dashpay#617: Pass scalar by reference in secp256k1_wnaf_const() 735fbde Merge dashpay#619: Clear a copied secret key after negation 16e8615 Install headers automatically 069870d Clear a copied secret key after negation 8979ec0 Pass scalar by reference in secp256k1_wnaf_const() 84a8085 Merge dashpay#612: Allow field_10x26_arm.s to compile for ARMv7 architecture d4d270a Allow field_10x26_arm.s to compile for ARMv7 architecture 248f046 Make sure we're not using an uninitialized variable in secp256k1_wnaf_const(...) 9ab96f7 Use trivial algorithm in ecmult_multi if scratch space is small dbed75d Undefine `STATIC_PRECOMPUTATION` if using the basic config 310111e Keep LDFLAGS if `--coverage` 74e2dbd JNI: fix use sig array 3cb057f Fix possible integer overflow in DER parsing git-subtree-dir: src/secp256k1 git-subtree-split: 2ed54da
