We are pleased to announce a new release of Valgrind, version 3.19.0, available from https://valgrind.org/downloads/current.html.
3.19.0 fixes a number of bugs and was tested against glibc-2.35, gcc-12 (pre-release) and linux 5.17.1 on GNU/Linux systems and tested on various FreeBSD systems. See the release notes below for details of changes. Our thanks to all those who contribute to Valgrind's development. This release represents a great deal of time, energy and effort on the part of many people. Happy and productive debugging and profiling, -- The Valgrind Developers ~~~~~~~~~~~~~~~~~~~~~~~~~~~~ This release supports X86/Linux, AMD64/Linux, ARM32/Linux, ARM64/Linux, PPC32/Linux, PPC64BE/Linux, PPC64LE/Linux, S390X/Linux, MIPS32/Linux, MIPS64/Linux, ARM/Android, ARM64/Android, MIPS32/Android, X86/Android, X86/Solaris, AMD64/Solaris, AMD64/MacOSX 10.12, X86/FreeBSD and AMD64/FreeBSD. There is also preliminary support for X86/macOS 10.13, AMD64/macOS 10.13 and nanoMIPS/Linux. * ==================== CORE CHANGES =================== * Fix Rust v0 name demangling. * The Linux rseq syscall is now implemented as (silently) returning ENOSYS. * Add FreeBSD syscall wrappers for __specialfd and __realpathat. * Remove FreeBSD dependencies on COMPAT10, which fixes compatibility with HardenedBSD * ================== PLATFORM CHANGES ================= * arm64: - ignore the "v8.x" architecture levels, only look at actual CPU features present. Fixes mismatch detected between RDMA and atomics features preventing startup on some QEMU configurations. - Implement LD{,A}XP and ST{,L}XP - Fix incorrect code emitted for doubleword CAS. * s390: - Fix sys_ipc semtimedop syscall - Fix VFLRX and WFLRX instructions - Fix EXRL instruction with negative offset * ppc64: - Reimplement the vbpermq instruction support to generate less Iops and avoid overflowing internal buffers. - Fix checking for scv support to avoid "Facility 'SCV' unavailable (12), exception" messages in dmsg. - Fix setting condition code for Vector Compare quad word instructions. - Fix fix lxsibzx, lxsihzx and lxsihzx instructions so they only load their respective sized data. - Fix the prefixed stq instruction in PC relative mode. * ==================== TOOL CHANGES =================== * Memcheck: - Speed up --track-origins=yes for large (in the range of hundreds to thousands of megabytes) mmap/munmaps. * DRD/Helgrind: - Several fixes for new versions of libstd++ using new posix try_lock functions * ==================== FIXED BUGS ==================== The following bugs have been fixed or resolved. Note that "n-i-bz" stands for "not in bugzilla" -- that is, a bug that was reported to us but never got a bugzilla entry. We encourage you to file bugs in bugzilla (https://bugs.kde.org/enter_bug.cgi?product=valgrind) rather than mailing the developers (or mailing lists) directly -- bugs that are not entered into bugzilla tend to get forgotten about or ignored. 403802 leak_cpp_interior fails with some reachable blocks different than expected 435732 memcheck/tests/leak_cpp_interior fails with gcc11 444242 s390x: Valgrind crashes on EXRL with negative offset 444399 arm64: unhandled instruction 0xC87F2D89 (LD{,A}XP and ST{,L}XP). == 434283 444481 gdb_server test failures on s390x 444495 dhat/tests/copy fails on s390x 444552 memcheck/tests/sem fails on s390x with glibc 2.34 444571 PPC, fix the lxsibzx and lxsihzx so they only load their respective sized data. 444836 PPC, pstq instruction for R=1 is not storing to the correct address. 444925 fexecve syscall wrapper not properly implemented 445032 valgrind/memcheck crash with SIGSEGV when SIGVTALRM timer used and libthr.so associated 445211 Fix out of tree builds 445300 [PATCH] Fix building tests with Musl 445011 SIGCHLD is sent when valgrind uses debuginfod-find 445354 arm64 backend: incorrect code emitted for doubleword CAS 445415 arm64 front end: alignment checks missing for atomic instructions 445504 Using C++ condition_variable results in bogus "mutex is locked simultaneously by two threads" warning 445607 Unhandled amd64-freebsd syscall: 247 445668 Inline stack frame generation is broken for Rust binaries 445916 Demangle Rust v0 symbols with .llvm suffix 446139 DRD/Helgrind with std::shared_timed_mutex::try_lock_until and try_lock_shared_until false positives 446138 DRD/Helgrind with std::timed_mutex::try_lock_until false positives 446281 Add a DRD suppression for fwrite 446103 Memcheck: `--track-origins=yes` causes extreme slowdowns for large mmap/munmap 446139 DRD/Helgrind with std::shared_timed_mutex::try_lock_until and try_lock_shared_until false 446251 TARGET_SIGNAL_THR added to enum target_signal 446823 FreeBSD - missing syscalls when using libzm4 447991 s390x: Valgrind indicates illegal instruction on wflrx 447995 Valgrind segfault on power10 due to hwcap checking code 449483 Powerpc: vcmpgtsq., vcmpgtuq,, vcmpequq. instructions not setting the condition code correctly. 449672 ppc64 --track-origins=yes failures because of bad cmov addHRegUse 449838 sigsegv liburing the 'impossible' happened for io_uring_setup 450025 Powerc: ACC file not implemented as a logical overlay of the VSR registers. 450437 Warn for execve syscall with argv or argv[0] being NULL 450536 Powerpc: valgrind throws 'facility scv unavailable exception' 451626 Syscall param bpf(attr->raw_tracepoint.name) points to unaddressable byte(s) 451827 [ppc64le] VEX temporary storage exhausted with several vbpermq instructions 451843 valgrind fails to start on a FreeBSD system which enforces W^X To see details of a given bug, visit https://bugs.kde.org/show_bug.cgi?id=XXXXXX where XXXXXX is the bug number as listed above.
