We are pleased to announce a new release of Valgrind, version 3.23.0, available from https://valgrind.org/downloads/current.html. 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, AMD64/FreeBSD and ARM64/FreeBSD There is also preliminary support for X86/macOS 10.13, AMD64/macOS 10.13 and nanoMIPS/Linux. * ==================== CORE CHANGES =================== * --track-fds=yes will now also warn about double closing of file descriptors. Printing the context where the file descriptor was originally opened and where it was previously closed. * --track-fds=yes also produces "real" errors now which can be suppressed and work with --error-exitcode. When combined with --xml the xml-output now also includes FdBadClose and FdNotClosed error kinds (see docs/internals/xml-output-protocol5.txt). * The option --show-error-list=no|yes now accepts a new value all. This indicates to also print the suppressed errors. This is useful to analyse which errors are suppressed by which suppression entries. The valgrind monitor command 'v.info all_errors' similarly now accepts a new optional argument 'also_suppressed' to show all errors including the suppressed errors. * ================== PLATFORM CHANGES ================= * Added ARM64 support for FreeBSD. * ARM64 now supports dotprod instructions (sdot/udot). * AMD64 better supports code build with -march=x86-64-v3. fused-multiple-add instructions (fma) are now emulated more accurately. And memcheck now handles __builtin_strcmp using 128/256 bit vectors with sse4.1, avx/avx2. * S390X added support for NNPA (neural network processing assist) facility vector instructions VCNF, VCLFNH, VCFN, VCLFNL, VCRNF and NNPA (z16/arch14). * X86 recognizes new binutils-2.42 nop patterns. * ==================== TOOL CHANGES =================== * The none tool now also supports xml output. * ==================== 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. 283429 ARM leak checking needs CLEAR_CALLER_SAVED_REGS 281059 Cannot connect to Oracle using valgrind 328563 make track-fds support xml output 362680 --error-exitcode not honored when file descriptor leaks are found 369723 __builtin_longjmp not supported in clang/llvm on Android arm64 target 390269 unhandled amd64-darwin syscall: unix:464 (openat_nocancel) 401284 False positive "Source and destination overlap in strncat" 428364 Signals inside io_uring_enter not handled 437790 valgrind reports "Conditional jump or move depends on uninitialised value" in memchr of macOS 10.12-10.15 460616 disInstr(arm64): unhandled instruction 0x4E819402 (dotprod/ASIMDDP) 463458 memcheck/tests/vcpu_fnfns fails when glibc is built for x86-64-v3 463463 none/tests/amd64/fma fails when executed on a x86-64-v3 system 466762 Add redirs for C23 free_sized() and free_aligned_sized() 466884 Missing writev uninit padding suppression for _XSend 471036 disInstr_AMD64: disInstr miscalculated next %rip on RORX imm8, m32/64, r32/6 471222 support tracking of file descriptors being double closed 474160 If errors-for-leak-kinds is specified, exit-on-first-error should only exit on one of the listed errors. 475498 Add reallocarray wrapper 476025 Vbit expected test results for Iop_CmpGT64Ux2 are wrong 476320 Build failure with GCC 476331 clean up generated/distributed filter scripts 476535 Difference in allocation size for massif/tests/overloaded-new between clang++/libc++ and g++/libstdc++ 476548 valgrind 3.22.0 fails on assertion when loading debuginfo file produced by mold 476708 valgrind-monitor.py regular expressions should use raw strings 476780 Extend strlcat and strlcpy wrappers to GNU libc 476787 Build of Valgrind 3.21.0 fails when SOLARIS_PT_SUNDWTRACE_THRP is defined 476887 WARNING: unhandled amd64-freebsd syscall: 578 477198 Add fchmodat2 syscall on linux 477628 Add mremap support for Solaris 477630 Include ucontext.h rather than sys/ucontext.h in Solaris sources 477719 vgdb incorrectly replies to qRcmd packet 478211 Redundant code for vgdb.c and Valgrind core tools 478624 Valgrind incompatibility with binutils-2.42 on x86 with new nop patterns (unhandled instruction bytes: 0x2E 0x8D 0xB4 0x26 478837 valgrind fails to read debug info for rust binaries 479041 Executables without RW sections do not trigger debuginfo reading 480052 WARNING: unhandled amd64-freebsd syscall: 580 480126 Build failure on Raspberry Pi 5 / OS 6.1.0-rpi7-rpi-v8 480405 valgrind 3.22.0 "m_debuginfo/image.c:586 (set_CEnt): Assertion '!sr_isError(sr)' failed." 480488 Add support for FreeBSD 13.3 480706 Unhandled syscall 325 (mlock2) 481127 amd64: Implement VFMADD213 for Iop_MAddF32 481131 [PATCH] x86 regtest: fix clobber lists in generated asm statements 481676 Build failure on Raspberry Pi 5 Ubuntu 23.10 with clang 481874 Add arm64 support for FreeBSD 483786 Incorrect parameter indexing in FreeBSD clock_nanosleep syscall wrapper 484002 Add suppression for invalid read in glibc's __wcpncpy_avx2() via wcsxfrm() 484426 aarch64: 0.5 gets rounded to 0 484480 False positives when using sem_trywait 484935 [patch] Valgrind reports false "Conditional jump or move depends on uninitialised value" errors for aarch64 signal handlers 485148 vfmadd213ss instruction is instrumented incorrectly (the remaining part of the register is cleared instead of kept unmodified) 485487 glibc built with -march=x86-64-v3 does not work due to ld.so strcmp 485778 Crash with --track-fds=all and --gen-suppressions=all n-i-bz Add redirect for memccpy 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.
