<p>An update that contains two features can now be installed.</p>
<h2>Description:</h2>
<p>This update for valgrind fixes the following issues:</p>
<ul>
<li>update to 3.27.1 (jsc#PED-15483):<ul>
<li>valgrind 3.27 "--fair-sched=yes" does not work</li>
<li>Valgrind incorrectly unpacks the result of sys_port (port_getn)</li>
<li>on error, leading to a ~60s wallclock time delay on every call</li>
<li>n-i-bz Update vg-lifespan (copyright) years</li>
<li>n-i-bz Use SSizeT for VG_(readlink) result in VG_(realpath)</li>
</ul>
</li>
<li>update to 3.27.0:<ul>
<li>VALGRIND_REPLACES_MALLOC Returns 1 if the tool replaces malloc.</li>
<li>VALGRIND_GET_TOOLNAME Get the running tool name as a string.
Takes two arguments, an input buffer pointer and the length of that buffer.</li>
<li>linux lightweight guard pages (madvise MADV_GUARD_INSTALL) supported</li>
<li>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. </li>
<li>If --max-guard-pages is not set explicitly,
then it will default to the --max-threads setting.</li>
<li>--num-callers now has a minimum value of 2.</li>
<li>x86: Support for SSE4.1 instructions has been ported from AMD64 to (32bit) x86.</li>
<li>s390x: Machine models older than z196 are no longer supported.</li>
<li>s390x: Support new z/Architecture features from the 15th edition.</li>
</ul>
</li>
<li>remove 32bit for all SLES 16 based products (jsc#PED-15782)</li>
<li>update to 3.26.0:<ul>
<li>Upgrade to the GNU General Public License version 3.</li>
<li>Control building documentation. When using make dist set the
Makefile BUILD_DOCS to none, all or html. none, does not build any documentation.</li>
<li>New VEX API function LibVEX_set_VexControl</li>
<li>The deprecated IROps: Iop_Clz32/64 and Iop_Ctz32/64 have been removed</li>
<li>The Linux Test Project (LTP) integration has been updated to v20250930.</li>
<li>--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.</li>
<li>With --xml=yes log output protocol 6 is now always used.</li>
<li>Add "bad" option for --track-fds. When --track-fds=bad is specified,
do not produce errors about unclosed file descriptors at program exit.</li>
<li>vgdb will now handle the qExecAndArgs packet.</li>
<li>DWARF inlined subroutine handling has been rewritten to work cross compile units.</li>
</ul>
</li>
<li>updated keyring from https://www.klomp.org/mark/gnupg-pub.txt</li>
</ul>
