reassign 1119972 valgrind affects 1119972 libntruprime thanks The problem appears reproducible:
https://ci.debian.net/packages/libn/libntruprime/testing/riscv64/65746038/#S11 I'm reassigning this to valgrind to get the attention of valgrind folks, I see that riscv64 was added as a valgrind target just recently. I recall something about valgrind learned to ignore libc optimization as false positives on other archs, is that what is missing for riscv64 here? /Simon Simon Josefsson <[email protected]> writes: > Package: libntruprime > Version: 0~20241021-3 > X-Debbugs-CC: Jan Mojžíš <[email protected]> > > librandombytes testing migration triggered a valgrind complaints in > libntruprime on riscv64: > > https://ci.debian.net/packages/libn/libntruprime/testing/riscv64/65744862/ > > Looks like a glibc or valgrind issue to me, and I'm guessing related to > an optimized implementation of bcmp. > > The autopkgtest run of libntruprime 0~20241021-4 is still pending, we > should know soon if this is reproducible or flaky. > > /Simon > > 5939s autopkgtest [05:04:02]: test valgrind-test-kem-sntrup1277: > [----------------------- > 5941s ntruprime version 20241021 > 5941s ntruprime arch riscv64 > 5941s cpuid 00000000 00000000 00000000 00000000 00000000 00000000 > 00000000 00000000 00000000 00000000 00000000 00000000 00000000 > 00000000 00000000 00000000 00000000 00000000 00000000 00000000 > 00000000 00000000 00000000 00000000 00000000 00000000 00000000 > 00000000 00000000 00000000 00000000 00000000 > 5941s valgrind 1 declassify 0 (expect false positives) > 5941s kem_sntrup1277 offset 0 > 5941s kem_sntrup1277 selected implementation factored compiler gcc > -Wall -fPIC -fwrapv -O3; cc (Debian 14.2.0-19) 14.2.0; Copyright (C) > 2024 Free Software Foundation, Inc.; This is free software; see the > source for copying conditions.
