-Subject: [PATCH] bin/automake: escape '{' in regexp pattern
-
-Based on perlre(1) documentation:
-.. in Perl v5.26, literal uses of a curly bracket will be required
-to be escaped, say by preceding them with a backslash ("\{" ) or
-enclosing them within square brackets ("[{]") ..
-
-References:
-https://bugzilla.redhat.com/1239379
-
-* bin/automake.in (substitute_ac_subst_variables): Escape the
-occurrence of '{' character.

-      * tests/misc/cut-huge-range.sh: On some systems returns_ may
-      use more memory, so incorporate that in the determination
-      of the ulimit value to use.  Noticed on ARMv7 with bash-4.4.12,

-
-When using the "DELAYBIND" feature, it turns out that .eqproc can be called with
-parameters that are not both procedures. In this case, it turns out, the
-expectation is for the operator to return 'false', rather than throw an error.

+Subject: [PATCH] Fix test failing on new GLib versions.
+
+This test fails on newer GLib version, because GLib exports a new public marshaller.
+The additional symbol making the test fail is:
+g_cclosure_marshal_BOOLEAN__BOXED_BOXED
+
+The fix makes the test ignore non-gtk related abi.
+This ensures if future marshallers are added to glib those will not pose a problem.
+
+The fix also ensures that the test still checks the gtk abi for identity, and
+that the library provides a superset of the required abi.
+
+Upstream reponse to this problem was:
+
+GLib added a new marshaller in its public API
+And the `abicheck.sh`in GTK+ 2.24 hasn't been updated because GTK+ 2.24 is in deep
+maintenance mode and very few people test it against newer versions of GLib

+ 
+ The normal approach to updating harfbuzz, therefore, is to pull the latest HB
+ source into a scratch directory and do a local build; then copy the original
+ sources AND the generated header mentioned above from the build directory into
+ the mozilla tree.
+ 
+ If the collection of source files changes, manual updates to moz.build may be
+ needed, as we don't use the upstream makefiles.
++
++The in-tree copy may be omitted during build by --with-system-harfbuzz.
++Make sure to keep pkg-config version check within old-configure.in in sync
++with checkout version or increment latest tag by one if it's not based
++on upstream release.

-* libtiff/tif_dirinfo.c, tif_dirread.c: add _TIFFCheckFieldIsValidForCodec(),
-and use it in TIFFReadDirectory() so as to ignore fields whose tag is a
-codec-specified tag but this codec is not enabled. This avoids TIFFGetField()
-to behave differently depending on whether the codec is enabled or not, and
-thus can avoid stack based buffer overflows in a number of TIFF utilities
-such as tiffsplit, tiffcmp, thumbnail, etc.

-Subject: [PATCH] Disallow namespace nodes in XPointer ranges
-
-Namespace nodes must be copied to avoid use-after-free errors.
-But they don't necessarily have a physical representation in a
-document, so simply disallow them in XPointer ranges.
-
-Found with afl-fuzz.
-
-Fixes CVE-2016-4658.

-Subject: [PATCH] Fix XPointer paths beginning with range-to
-
-The old code would invoke the broken xmlXPtrRangeToFunction. range-to
-isn't really a function but a special kind of location step. Remove
-this function and always handle range-to in the XPath code.
-
-The old xmlXPtrRangeToFunction could also be abused to trigger a
-use-after-free error with the potential for remote code execution.
-
-Found with afl-fuzz.
-
-Fixes CVE-2016-5131.

-Subject: [PATCH] Fix handling of parameter-entity references
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-There were two bugs where parameter-entity references could lead to an
-unexpected change of the input buffer in xmlParseNameComplex and
-xmlDictLookup being called with an invalid pointer.
-
-Percent sign in DTD Names
-=========================
-
-The NEXTL macro used to call xmlParserHandlePEReference. When parsing
-"complex" names inside the DTD, this could result in entity expansion
-which created a new input buffer. The fix is to simply remove the call
-to xmlParserHandlePEReference from the NEXTL macro. This is safe because
-no users of the macro require expansion of parameter entities.
-
-- xmlParseNameComplex
-- xmlParseNCNameComplex
-- xmlParseNmtoken
-
-The percent sign is not allowed in names, which are grammatical tokens.
-
-- xmlParseEntityValue
-
-Parameter-entity references in entity values are expanded but this
-happens in a separate step in this function.
-
-- xmlParseSystemLiteral
-
-Parameter-entity references are ignored in the system literal.
-
-- xmlParseAttValueComplex
-- xmlParseCharDataComplex
-- xmlParseCommentComplex
-- xmlParsePI
-- xmlParseCDSect
-
-Parameter-entity references are ignored outside the DTD.
-
-- xmlLoadEntityContent
-
-This function is only called from xmlStringLenDecodeEntities and
-entities are replaced in a separate step immediately after the function
-call.
-
-This bug could also be triggered with an internal subset and double
-entity expansion.
-
-This fixes bug 766956 initially reported by Wei Lei and independently by
-Chromium's ClusterFuzz, Hanno Böck, and Marco Grassi. Thanks to everyone
-involved.
-
-xmlParseNameComplex with XML_PARSE_OLD10
-========================================
-
-When parsing Names inside an expanded parameter entity with the
-XML_PARSE_OLD10 option, xmlParseNameComplex would call xmlGROW via the
-GROW macro if the input buffer was exhausted. At the end of the
-parameter entity's replacement text, this function would then call
-xmlPopInput which invalidated the input buffer.
-
-There should be no need to invoke GROW in this situation because the
-buffer is grown periodically every XML_PARSER_CHUNK_SIZE characters and,
-at least for UTF-8, in xmlCurrentChar. This also matches the code path
-executed when XML_PARSE_OLD10 is not set.
-
-This fixes bugs 781205 (CVE-2017-9049) and 781361 (CVE-2017-9050).
-Thanks to Marcel Böhme and Thuan Pham for the report.
-
-Additional hardening
-====================
-
-A separate check was added in xmlParseNameComplex to validate the
-buffer size.

-Subject: [PATCH] Fix heap overread in xsltFormatNumberConversion
-
-An empty decimal-separator could cause a heap overread. This can be
-exploited to leak a couple of bytes after the buffer that holds the
-pattern string.
-
-Found with afl-fuzz and ASan.

-Subject: [PATCH] Check for integer overflow in xsltAddTextString

-Limit buffer size in xsltAddTextString to INT_MAX. The issue can be

-
-ftp://invisible-island.net/ncurses/6.0/ncurses-6.0-20170701.patch.gz
-
-Excerpt from patch release announcement:
-
- + add/improve checks in tic's parser to address invalid input
-   (Redhat #1464684, #1464685, #1464686, #1464691).
-   + alloc_entry.c, add a check for a null-pointer.
-   + parse_entry.c, add several checks for valid pointers as well as
-     one check to ensure that a single character on a line is not
-     treated as the 2-character termcap short-name.
- + the fixes for Redhat #1464685 obscured a problem subsequently
-   reported in Redhat #1464687; the given test-case was no longer
-   reproducible.  Testing without the fixes for the earlier reports
-   showed a problem with buffer overflow in dump_entry.c, which is
-   addressed by reducing the use of a fixed-size buffer.

-Issue #29188: Support glibc 2.24 on Linux: don't use getentropy() function but
-read from /dev/urandom to get random bytes, for example in os.urandom().  On
-Linux, getentropy() is implemented which getrandom() is blocking mode, whereas
-os.urandom() should not block.

-Issue #29157: Prefer getrandom() over getentropy()
-
-Copy and then adapt Python/random.c from default branch. Difference between 3.5
-and default branches:
-
-* Python 3.5 only uses getrandom() in non-blocking mode: flags=GRND_NONBLOCK
-* If getrandom() fails with EAGAIN: py_getrandom() immediately fails and
-  remembers that getrandom() doesn't work.
-* Python 3.5 has no _PyOS_URandomNonblock() function: _PyOS_URandom()
-  works in non-blocking mode on Python 3.5

+Subject: [PATCH] herd: 'herd status' now sorts the result.
+
+Partly fixes <https://bugs.gnu.org/30299>.
+Reported by Mark H Weaver <mhw@netris.org>.
+
+Previously 'tests/basic.sh' could occasionally fail on:
+
+  test "`$herd status`" == "$pristine_status"
+
+because the order of stopped services were not always the same.  Indeed,
+those services come from 'service-list' on the shepherd side, which uses
+'hash-fold' to traverse the service hash table, and the traversal order
+of 'hash-fold' is undefined.
+
+* modules/shepherd/scripts/herd.scm (display-status-summary)[service<?]:
+New procedure.
+[display-services]: Call 'sort' and use the above.
