Affected Products:

  * Development Tools Module 15-SP7
  * SUSE Linux Enterprise Desktop 15 SP7
  * SUSE Linux Enterprise Real Time 15 SP7
  * SUSE Linux Enterprise Server 15 SP7
  * SUSE Linux Enterprise Server for SAP Applications 15 SP7

  
  
An update that contains two features can now be installed.

## Description:

This update for valgrind fixes the following issues:

  * update to 3.27.1 (jsc#PED-15483):
    * valgrind 3.27 "\--fair-sched=yes" does not work
    * Valgrind incorrectly unpacks the result of sys_port (port_getn)
    * on error, leading to a ~60s wallclock time delay on every call
    * n-i-bz Update vg-lifespan (copyright) years
    * n-i-bz Use SSizeT for VG_(readlink) result in VG_(realpath)
  * update to 3.27.0:
    * VALGRIND_REPLACES_MALLOC Returns 1 if the tool replaces malloc.
    * VALGRIND_GET_TOOLNAME Get the running tool name as a string. Takes two arguments, an input buffer pointer and the length of that buffer.
    * linux lightweight guard pages (madvise MADV_GUARD_INSTALL) supported
    * glibc 2.42+ (with linux 6.13+) uses MADV_GUARD_INSTALL to setup stack guard pages. These lightweight guard pages are now supported under valgrind. 
    * If --max-guard-pages is not set explicitly, then it will default to the --max-threads setting.
    * \--num-callers now has a minimum value of 2.
    * x86: Support for SSE4.1 instructions has been ported from AMD64 to (32bit) x86.
    * s390x: Machine models older than z196 are no longer supported.
    * s390x: Support new z/Architecture features from the 15th edition.
  * remove 32bit for all SLES 16 based products (jsc#PED-15782)
  * update to 3.26.0:
    * Upgrade to the GNU General Public License version 3.
    * Control building documentation. When using make dist set the Makefile BUILD_DOCS to none, all or html. none, does not build any documentation.
    * New VEX API function LibVEX_set_VexControl
    * The deprecated IROps: Iop_Clz32/64 and Iop_Ctz32/64 have been removed
    * The Linux Test Project (LTP) integration has been updated to v20250930.
    * \--modify-fds=yes has been added. It acts like --modify-fds=high (the highest available file descriptor is returned first) except when when the lowers stdin/stdout/stderr (file descriptors 0, 1, 2) are available.
    * With --xml=yes log output protocol 6 is now always used.
    * Add "bad" option for --track-fds. When --track-fds=bad is specified, do not produce errors about unclosed file descriptors at program exit.
    * vgdb will now handle the qExecAndArgs packet.
    * DWARF inlined subroutine handling has been rewritten to work cross compile units.
  * updated keyring from https://www.klomp.org/mark/gnupg-pub.txt
