coreutils/coreutils-bnc#697897-setsid.patch
Bernhard Voelker 26558dd009 - Avoid segmentation fault in "uniq" with long line input (bnc#796243, VUL-1)
* src/cut.c: Instead of usig unreliable alloca() stack allocation,
    use heap allocation via xmalloc()+free().
    (coreutils-i18n.patch)
- Fix test-suite errors (bnc#798261).
  * tests/cp/fiemap-FMR: Fix path to src directory and declare
    require_valgrind_ function.
    (coreutils-cp-corrupt-fragmented-sparse.patch)
  * tests/misc/cut:
    Fix src/cut.c to properly pass output-delimiter tests.
    Synchronize cut.c related part of the i18n patch with Fedora's.
    Merge coreutils-i18n-infloop.patch into coreutils-i18n.patch.
    Merge coreutils-i18n-uninit.patch into coreutils-i18n.patch.
    In tests/misc/cut, do not replace the non-i18n error messages.
    (coreutils-i18n.patch)
  * tests/rm/ext3-perf:
    This test failed due to heavy parallel CPU and/or disk load because it
    is based on timeouts. Do not run the test-suite with 'make -jN.
    (coreutils.spec, coreutils-testsuite.spec)
  * Further spec changes:
    Run more tests: also run "very expensive" tests; add acl, python-pyinotify,
    strace and valgrind to the build requirements.
    Remove patch5 and patch6 as they are now merged into coreutils-i18n.patch
    (see above).
    (coreutils.spec, coreutils-testsuite.spec)
- Maintenance changes:
  (coreutils.spec, coreutils-testsuite.spec)
  * Add perl and texinfo to the build requirements as they are needed to
    re-generate the man pages and the texinfo documentation.
  * Remove already-active "-Wall" compiler option from CFLAGS variable.
  * Install the compressed test-suite.log into the documentation directory
    of the coreutils-testsuite package (section %check and %files).
  * Properly guard the spec sections for the coreutils and the
    coreutils-testsuite package.
  * Update patches to reflect new line numbers.
