We are pleased to announce a new release of Valgrind, version 3.25.0, available from https://valgrind.org/downloads/current.html.
This release adds initial support for RISCV64/Linux, the GDB remote packet 'x', zstd compressed debug sections, Linux Test Project testsuite integration, numerous fixes for Illumos, FreeBSD atexit filters and getrlimitusage syscall support, Linux syscall support for landlock*, io_pgetevents, open_tree, move_mount, fsopen, fsconfig, fsmount, fspick, userfaultfd, s390x BPP, BPRP, PPA and NIAI instruction support, --track-fds=yes improvements and a new --modify-fds=high option, and an helgrind --check-cond-signal-mutex=yes|no option. See the release notes below for details of the 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 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Release 3.25.0 (25 Apr 2025) ~~~~~~~~~~~~~~~~~~~~~~~~~~~~ This release supports X86/Linux, AMD64/Linux, ARM32/Linux, ARM64/Linux, PPC32/Linux, PPC64BE/Linux, PPC64LE/Linux, S390X/Linux, MIPS32/Linux, MIPS64/Linux, RISCV64/Linux, ARM/Android, ARM64/Android, MIPS32/Android, X86/Android, X86/Solaris, AMD64/Solaris, AMD64/MacOSX 10.12, X86/FreeBSD, AMD64/FreeBSD and ARM64/FreeBSD There is also preliminary support for X86/macOS 10.13, AMD64/macOS 10.13 and nanoMIPS/Linux. * ==================== CORE CHANGES =================== * The valgrind gdbserver now supports the GDB remote protocol packet 'x addr,len' (available in GDB release >= 16). The x packet can reduce the time taken by GDB to read memory from valgrind. * Valgrind now supports zstd compressed debug sections. * The Linux Test Project (ltp) is integrated in the testsuite try 'make ltpchecks' (this will take a while and will point out various missing syscalls and valgrind crashes!) * ================== PLATFORM CHANGES ================= * Added RISCV64 support for Linux. Specifically for the RV64GC instruction set. * Numerous bug fixes for Illumos, in particular fixed a Valgrind crash whenever a signal handler was called. * On FreeBSD, a change to the libc code that runs atexit handlers was causing Helgrind to produce an extra error about exiting threads still holding locks for. This applied to every multithreaded application. The extra error is now filtered out. A syscall wrapper had been added for getrlimitusage. * On Linux various new syscalls are supported (landlock*, io_pgetevents, open_tree, move_mount, fsopen, fsconfig, fsmount, fspick, userfaultfd). * s390x has support for various new instructions (BPP, BPRP, PPA and NIAI). * ==================== TOOL CHANGES =================== * The --track-fds=yes and --track-fds=all options now treat all inherited file descriptors the same as 0, 1, 2 (stdin/out/err). And when the stdin/out/err descriptors are reassigned they are now treated as normal (non-inherited) file descriptors. * A new option --modify-fds=high can be used together with --track-fds=yes to create new file descriptors with the highest possible number (and then decreasing) instead of always using the lowest possible number (which is required by POSIX). This will help catch issues where a file descriptor number might normally be reused between a close and another open call. * Helgrind: There is a change to warnings about calls to pthread_cond_signal and pthread_cond_broadcast when the associated mutex is unlocked. Previously Helgrind would always warn about this. Now this error is controlled by a command line option, --check-cond-signal-mutex=yes|no. The default is no. This change has been made because some C and C++ standard libraries use pthread_cond_signal/pthread_cond_broadcast in this way. Users are obliged to use suppressions if they wish to avoid this noise. * ==================== 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. 290061 pie elf always loaded at 0x108000 396415 Valgrind is not looking up $ORIGIN rpath of shebang programs 420682 io_pgetevents is not supported 468575 Add support for RISC-V 469782 Valgrind does not support zstd-compressed debug sections 487296 --track-fds=yes and --track-fds=all report erroneous information when fds 0, 1, or 2 are used as non-std 489913 WARNING: unhandled amd64-linux syscall: 444 (landlock_create_ruleset) 493433 Add --modify-fds=[no|high] option 494246 syscall fsopen not wrapped 494327 Crash when running Helgrind built with #define TRACE_PTH_FNS 1 494337 All threaded applications cause still holding lock errors 495488 Add FreeBSD getrlimitusage syscall wrapper 495816 s390x: Fix disassembler segfault for C[G]RT and CL[G]RT 495817 s390x: Disassembly to match objdump -d output 496370 Illumos: signal handling is broken 496571 False positive for null key passed to bpf_map_get_next_key syscall. 496950 s390x: Fix hardware capabilities and EmFail codes 497130 Recognize new DWARF5 DW_LANG constants 497455 Update drd/scripts/download-and-build-gcc 497723 Enabling Ada demangling breaks callgrind differentiation between overloaded functions and procedures 498037 s390x: Add disassembly checker 498143 False positive on EVIOCGRAB ioctl 498317 FdBadUse is not a valid CoreError type in a suppression even though it's generated by --gen-suppressions=yes 498421 s390x: support BPP, BPRP and NIAI insns 498422 s390x: Fix VLRL and VSTRL insns 498492 none/tests/amd64/lzcnt64 crashes on FreeBSD compiled with clang 498629 s390x: Fix S[L]HHHR and S[L]HHLR insns 498632 s390x: Fix LNGFR insn 498942 s390x: Rework s390_disasm interface 499183 FreeBSD: differences in avx-vmovq output 499212 mmap() with MAP_ALIGNED() returns unaligned pointer 501119 memcheck/tests/pointer-trace fails when run on NFS filesystem 501194 Fix ML_(check_macho_and_get_rw_loads) so that it is correct for any number of segment commands 501348 glibc built with -march=x86-64-v3 does not work due to ld.so memcmp 501479 Illumos DRD pthread_mutex_init wrapper errors 501365 syscall userfaultfd not wrapped 501846 Add x86 Linux shm wrappers 501850 FreeBSD syscall arguments 7 and 8 incorrect. 501893 Missing suppression for __wcscat_avx2 (strcat-strlen-avx2.h.S:68)? 502126 glibc 2.41 extra syscall_cancel frames 502288 s390x: Memcheck false positives with NNPA last tensor dimension 502324 s390x: Memcheck false positives with TMxx and TM/TMY 502679 Use LTP for testing valgrind 502871 Make Helgrind "pthread_cond_{signal,broadcast}: dubious: associated lock is not held by any thread" optional 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.
