Previously, test/relaxng/ambig_name-class2.xml would fail to validate
against test/relaxng/ambig_name-class2.rng:

Previously, test/relaxng/ambig_name-class.xml would fail to validate
for a simple reason -- interleave within "open-name-class" context
is supposed to be fine with whatever else is pending the consumption,
since effectively, it's unrelated from a higher parsing perspective.

Consolidate code paths evaluating XPath predicates and filters.
Don't push context node on stack when evaluating predicates. I have no
idea why this was done. It seems completely useless and trying to pop
the context node from a corrupted stack has already caused security
issues.
Filter nodesets in-place and don't create node sets with NULL gaps which
allows to simplify merging a great deal. Simply move matched nodes
backward and create a compact node set.
Merge xmlXPathCompOpEvalPositionalPredicate into
xmlXPathCompOpEvalPredicate.
Rewrite conversion of double to int in xmlXPathSubstringFunction, adding
range checks to avoid undefined behavior. Make sure to add start and
length as floating-point numbers before converting to int. Fix a bug
when rounding negative start indices.
Remove unneeded calls to xmlXPathIs{Inf,NaN} and rely on IEEE math
instead. Avoid computing the string length. xmlUTF8Strsub works as
expected if the length of the requested substring exceeds the input.
Found with libFuzzer and UBSan.
When including a grammar from another grammar, we need to make sure that any
redefines of starts and includes that that grammar does inside any of its
include elements are also removed.
The pattern nameClass allows for nested choice elements, for example
<name>
<choice>
<choice>
<name>a</name>
<name>b</name>
</choice>
<name>c</name>
</choice>
</name>
which is semantically equivalent to
<name>
<choice>
<name>a</name>
<name>b</name>
<name>c</name>
</choice>
</name>
The old code didn’t handle this correctly, as it never expected a choice inside
another choice. This patch fixes this by flattening any nested choices.
This pattern of nested choice elements comes up in RELAX NG simplification,
where all choice elements are rewritten in this nested manner, see section 4.12
of the RELAX NG specification.
RELAX NG allows for div elements inside of include elements. We need to look
inside those div elements for start and define elements that may be redefining
start and define elements in the included grammar.
Fix two bugs in xmlXPathNodeValHash which could lead to errors when
comparing nodesets to strings:
- Only use contents of text nodes to compute the hash for element nodes.
Comments, PIs, and other node types don't affect the string-value and
must be ignored.
- Reset `string` to NULL for node types other than text.

https://mail.gnome.org/archives/xml/2017-September/msg00016.html
This reverts commit 79c8a6b which caused a serious regression in
streaming mode.
Also reverts part of commit 52ceced "Fix infinite loops with push
parser in recovery mode".
Fixes bug 786554.
When expanding a parameter entity in a DTD, infinite recursion could
lead to an infinite loop or memory exhaustion.
Thanks to Wei Lei for the first of many reports.
Fixes bug 759579.
Make sure to finish all entities in the internal subset. Nevertheless,
readd a sanity check in xmlParseStartTag2 that was lost in my previous
commit. Also add a sanity check in xmlPopInput. Popping an input
unexpectedly was the source of many recent memory bugs. The check
doesn't mitigate such issues but helps with diagnosis.
Always base entity boundary checks on the input ID, not the input
pointer. The pointer could have been reallocated to the old address.
Always throw a well-formedness error if a boundary check fails. In a
few places, a validity error was thrown.
Fix a few error codes and improve indentation.
test/HTML/758518-entity.html exposed a bug in pushParseTest() in
runtest.c which assumed that an input file was at least 4 bytes long.
That test case is only 3 bytes, so we now take the minimum of 4 bytes
or the length of the test input. We also now use 'chunkSize' in place
of the hard-coded value '1024' later in the function.
Before, truncated UTF-8 sequences at the end of a file were treated as
EOF. Create an error message containing the offending bytes.
xmlStringCurrentChar would also print characters from the input stream,
not the string it's working on.
xmlSnprintfElementContent failed to correctly check the available
buffer space in two locations.
Fixes bug 781333 (CVE-2017-9047) and bug 781701 (CVE-2017-9048).
Thanks to Marcel Böhme and Thuan Pham for the report.
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.
Don't count leading zeros towards the fraction size limit. This allows
to parse numbers like
0.0000000000000000000000000000000000000000000000000000000001
which is the only standard-conformant way to represent such numbers, as
scientific notation isn't allowed in XPath 1.0. (It is allowed in XPath
2.0 and in libxml2 as an extension, though.)
Overall accuracy is still bad, see bug 783238.
Use the C library's floor and ceil functions. The old code was overly
complicated for no apparent reason and could result in undefined
behavior when handling NaNs (found with afl-fuzz and UBSan).
Fix wrong comment in xmlXPathRoundFunction. The implementation was
already following the spec and rounding half up.
When traversing the "preceding" axis from an attribute node, we must
first go up to the attribute's containing element. Otherwise, text
children of other attributes could be returned. This made it possible
to hit a code path in xmlXPathNextAncestor which contained another bug:
The attribute node was initialized with the context node instead of the
current node. Normally, this code path is only hit via
xmlXPathNextAncestorOrSelf in which case the current and context node
are the same.
The combination of the two bugs could result in an infinite loop, found
with libFuzzer.
Traversing the "following" and the "preceding" axis from namespace nodes
should be handled similarly. This wasn't supported at all previously.
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.

Make sure that xmlXPathNodeSetAddNs is called for namespace nodes when
matched with a namespace::node() step. This correctly sets the parent
of namespace nodes. Note that xmlXPathNodeSetAddNs must only be called
if working on the namespace axis. Otherwise, the context node is not
the parent of the namespace node and the standard XP_TEST_HIT macro
must be invoked. This explains the errors in the C14N tests that the
old TODO comment mentioned.

When hitting the end of the current input buffer while parsing
a name we could end up loosing the beginning of the name, which
led to various issues.
For https://bugzilla.gnome.org/show_bug.cgi?id=737840
the fix for 724903 introduced a regression on external entities carrying
IDs, revert that patch in part and add a specific test to avoid readding it
If the context node is an attribute, the attribute itself is on the
descendant-or-self axis. The principal node type of this axis is element,
so the only node test that can return the attribute is "node()". In other
words, "@attr/descendant-or-self::node()" is equivalent to "@attr".
This matches the behavior of Saxon-CE.
https://bugzilla.gnome.org/show_bug.cgi?id=698550
Somehow the behaviour of the internal parser routine changed
