Quebracabezas! Magic words for silo/string-table corruption

Hi!
I love this bug (it has cost me so much time and is so bizarre!). I was investigating some extremely odd AppStream behavior which I thought was a bug in my token processing code. Ultimately though it turned out that if you put in a bunch of magic words, the silo gets a corrupted string table and creates a completely weird DOM that kind of looks like memory was read at random.

I really hope others can reproduce this too!
The quickest way to reproduce this issue is to add these lines:

xb_builder_node_add_token (id, "paciencia");
xb_builder_node_add_token (id, "posta");
xb_builder_node_add_token (id, "prasentation");
xb_builder_node_add_token (id, "proyectos");
xb_builder_node_add_token (id, "puntuació");
xb_builder_node_add_token (id, "puzl");

xb_builder_node_add_token (id, "quebracabezas");
xb_builder_node_add_token (id, "raspakovnj");
xb_builder_node_add_token (id, "riječ");
xb_builder_node_add_token (id, "ripador");
xb_builder_node_add_token (id, "riverbero");

xb_builder_node_add_token (id, "sécurisé");
xb_builder_node_add_token (id, "seguretat");
xb_builder_node_add_token (id, "skanowani");
xb_builder_node_add_token (id, "slika");
xb_builder_node_add_token (id, "slika");
xb_builder_node_add_token (id, "slika");
xb_builder_node_add_token (id, "songtek");
xb_builder_node_add_token (id, "strategická");
xb_builder_node_add_token (id, "tahak");

xb_builder_node_add_token (id, "tallennin");
xb_builder_node_add_token (id, "teleporti");
xb_builder_node_add_token (id, "testu");
xb_builder_node_add_token (id, "torlő");
xb_builder_node_add_token (id, "traçar");
xb_builder_node_add_token (id, "udelat");
xb_builder_node_add_token (id, "vídeo");
xb_builder_node_add_token (id, "wiedergab");
xb_builder_node_add_token (id, "wtyczki");
xb_builder_node_add_token (id, "zvuk");

to line 2100 in the self test: https://github.com/hughsie/libxmlb/blob/main/src/xb-self-test.c#L2100

The test should then suddenly be unable to read the generated silo, failing with:

ERROR:../src/xb-self-test.c:2186:xb_builder_node_func: assertion failed ("<components origin=\"lvfs\">" "<component type=\"desktop\">" "<id>gimp.desktop</id>" "<icon type=\"stock\">dave</icon>" "<description>hello <em>world!</em>" "</description>" "</component>" "</components>" == xml):
("<components origin=\"lvfs\"><component type=\"desktop\"><id>gimp.desktop</id><icon type=\"stock\">dave</icon><description>hello <em>world!</em></description></component></components>" == "<onents in=\"\"><onent =\"top\"><con>.desktop</con>< =\"k\"></><ription>o <rigin>d!</rigin></ription></onent></onents>")

The weirdest thing is that if you remove some of these words, the test will suddenly pass again... I tried to remove as many terms as possible, and that's the smallest list that I could come up with.
@hughsie Do you have any idea what could be going on here? I suspect some unicode or integer overflow fun, but the former seems unlikely as even Japanese characters are processed just fine, and the latter just doesn't make much sense either.

XbSilo xb_builder_node_unlink: assertion 'XB_IS_BUILDER_NODE (self)' failed

Hello,

On debian unstable (libxmlb 0.1.15) I get the following GLIB critical coming from libxmlb:

xb_builder_node_unlink: assertion 'XB_IS_BUILDER_NODE (self)' failed

This can be easily reproduce with the following commands:

$ appstreamcli convert /var/lib/app-info/yaml/ftp.be.debian.org_debian_dists_sid_main_dep11_Components-amd64.yml.gz /tmp/Components-amd64.xml
$ /usr/lib/x86_64-linux-gnu/xb-tool compile /tmp/Components-amd64.xmlb /tmp/Components-amd64.xml
(xb-tool:1900889): XbSilo-CRITICAL **: 19:03:14.826: xb_builder_node_unlink: assertion 'XB_IS_BUILDER_NODE (self)' failed
[...]

If somebody want to test and is not running a debian the yaml file can be downloaded at: http://ftp.debian.org/debian/dists/sid/main/dep11/Components-amd64.yml.gz

The original bug has been opened on the gnome-shell project, but the problem seems to be in libxmlb in the end.

xb_string_search() is UTF8 unfriendly

This is tricky to fix as xb_string_search is in the fast path and we don't want to allocate memory.

[Feature Request] making lzma optional

with the recent xz CVE would it be possible to make lzma optional aswell in meson options? without knowing much of the source code it is perhaps to tightly integrated? but never hurts to ask.

Please install xb-tool into bin instead of libexec

I am curious why xb-tool is installed to libexec instead of bin, as README.md suggests it should be callable by the user and thus available in PATH, but typically libexec is not included in PATH, and arguably it shouldn't be. from https://refspecs.linuxfoundation.org/FHS_3.0/fhs/ch04s07.html:

/usr/libexec includes internal binaries that are not intended to be executed directly by users or shell scripts.

Thanks!

xb-self-test intermittently hang

The autopkgtests for libxmlb in Ubuntu failed a couple of times recently on amd64, and I managed to reproduce the failure by running the test in an infinite loop.

I'm attaching a full log. The test always appears to hang after ok 14 /libxmlb/builder{ensure}, and it prints Executing: libxmlb/libxmlb.test every 5 seconds until it times out after 5 minutes.

This is on Ubuntu groovy (amd64).

Converters don't nest - can't handle .yml.gz

libxmlb assumes the result of a gzipped file is XML, instead of checking the MIME type of the decompressed data. This means that .yml.gz files can't be handled by the converter.

Test failure

Hi,

I’m trying to build libxmlb in order to update fwupd to 1.2.0, but I have a failure in tests: https://paste.xinu.at/oWV40/

Any hint?

XbBuilder could work without explicit xb_builder_add_locale() calls

Currently one must call xb_builder_add_locale() on an XbBuilder object to add system locales before using xb_builder_compile(), at least if one is using XB_BUILDER_COMPILE_FLAG_SINGLE_LANG. @pwithnall proposed an alternative way for it to work here:

Seems a bit odd that most instances of XbBuilder have to have this loop called on them, using the results of g_get_language_names(), before they will work properly.
Looking at the implementation, it basically checks any node which has an xml:lang attribute set. If the attribute value is not in the set of locales, that node is ignored.
Seems like it would be faster and more convenient to have an XbBuilder:use-system-locales property, which tells XbBuilder to check for set inclusion against g_get_language_names() internally. Then you don’t need to set it up, or copy a list of strings.

Export XML node without children in "collapsed" form?

I'm using xb_node_export() for a node that I know doesn't have any children, and the XML built is in the following format:

<node attr1="val1" attr2="val2"></node>

Is there any way to export the node so that it looks like this instead?

<node attr1="val1" attr2="val2" />

None of the XbNodeExportFlags seem to support this?

For some context, I'm using libxmlb to parse and generate XML transferred from/to the bootloader/programmer of a wwan device and it looks like the embedded XML parser is not very robust...

Errors compiling on Windows

Hi, I am trying to build libxmlb on Windows so that I can build AppStream and upgrade libadwaita to version 1.4. I have zstd, docs, and introspection turned off for the build.

Mention build arguments to decrease dependencies

Please mention meson build -Dintrospection=false -Dgtkdoc=false -Dcli=false prominently in the README, because they significantly decrease the dependencies needed.

Thanks!

Tag a new release

Would you mind tagging a new release? I'd like to get 04e88ac into Debian/Ubuntu to unblock https://bugs.launchpad.net/ubuntu/+source/gnome-software/+bug/1817223 but rather not just cherry-pick the the fix if possible.

Add a way to return an empty resultset without using G_IO_ERROR_NOT_FOUND

Currently, libxmlb queries will set the error G_IO_ERROR_NOT_FOUND if they find no matching elements. A lot of queries will often return no results (that’s just the way XML is), so this code path is hit often. If a lot of queries are run quickly (for example, when loading gnome-software), the cost of allocating a GError to indicate an empty resultset becomes measurable.

It would be nice if libxmlb would provide an alternate codepath which indicates an empty resultset some other way, without needing an allocation.

This might be possible without any new API: the documentation for the xb_silo_query() functions already says they return NULL if unfound, so callers should already be handling that. If that’s acceptable, we could just basically remove the g_set_error (G_IO_ERROR_NOT_FOUND) calls.

See https://gitlab.gnome.org/GNOME/gnome-software/-/merge_requests/1749 for some more context.

Tag mismatch errors in some special XML with comments

Hey! Looks like libxmlb is failing to process an XML file that contains some initial comments in the following format:

<?xml version="1.0" ?>
<data>
  <!--NOTE: This is an ** Autogenerated file **-->
  <!--BlockSize = 256 KB-->
  <!--PageSize  = 4 KB-->
  <!--NUM_PARTITION_SECTORS  = 131072-->
  <program />
</data>

Not sure if this is because the XML comments are malformed, or because the parser cannot process them correctly.
I'm attaching here a simple tester program attempting to process the previous XML contents, which gves this output:

$ ./test-xmlb test.xml 
** Message: 22:57:24.135: loading bytes in builder source
** (process:261125): WARNING **: 23:03:13.864: builder compile failed: failed to compile 635684fc0f341ab67d8aee0176bea5d9d9104dc2: Mismatched XML

Support the XPath `and` operator

In an AppStream query I was writing today, it would have been useful to have support for the XPath and operator. Is that likely to be added?

The query was:

custom/value[@key='SomeKey' and text()='true']

Hidden files also monitored when using XB_BUILDER_SOURCE_FLAG_WATCH_DIRECTORY

While debugging GNOME Software and doing upgrades of packages in alpine linux, I get (lots of) repeated debug messages of invalidation of hidden files. Similar to those below:

XbSilo /usr/share/applications/.mimeinfo.cache.DLPXG1 changed, invalidating
XbSilo /usr/share/metainfo/.apk.$long_hash changed, invalidating

Looks like alpine's package manager, apk, is creating temporary files during upgrades. Looking at the MR that introduced the flag and the corresponding one in Software, it looks like that was never the intention.

The small snippet below would probably fix it, but I am not sure if this is something desirable, or if the current behavior is the intended. So I thought I would open an issue before creating a MR.

Strange behavior when searching for tokens

Hi!

I was debugging some strange behavior in AppStream which may actually be an issue with libxmlb (or at the very least I need some guidance on what the correct approach is here).

AppStream performs its own stemming, so a term like strategy is stemmed to strategi (making it no longer a fulltext search match). AppStream adds the stemmed terms to a node using xb_builder_node_add_token ();.
I have verified that the tokens are actually added, they show up in xb-tool dump output in the correct places.

Now, I first perform a query to get all component nodes in the XML, like this: cpt_nodes = xb_silo_query (csec->silo, "components/component", 0, &tmp_error);

A new query is constructed like this:

query = xb_query_new (csec->silo,
			queries[j].xpath,
			&error_query);

With XPath summary[text()~=?]

Then I iterate over all component nodes cpt_node with search term term (a single, stemmed word):

g_auto(XbQueryContext) context = XB_QUERY_CONTEXT_INIT ();

xb_value_bindings_bind_str (xb_query_context_get_bindings (&context),
			        0,
			        term,
			        NULL);
n = xb_node_query_with_context (cpt_node, query, &context, NULL);

So, the stemmed strategi does not show up in the full text of summary, "A strategy game", it has however been added to the node as token before. So I would expect this code to find the node and yield a result. This is not what happens though.

In XbSilo's xb_silo_machine_func_search_cb, only op2 has XB_OPCODE_FLAG_TOKENIZED set, so we do not perform the fast TOKEN/TOKEN search: https://github.com/hughsie/libxmlb/blob/main/src/xb-silo.c#L1520

Instead, the code always falls back to the slower full-text search below, which in this case does not yield any result.

Why does op1 (containing the "strategi" string) not have that one as token, and why does this inevitably always fall back to the slower search path? Am I supposed to bind the query value differently? Dirty hacks like just adding the string as a token as well to the opcode do not seem to work, so I think I am missing something here / do not understand how tokens relate to text search in libxmlb in concept.

I'm glad for any help :-)

Second predicate doesn’t filter results of first

If I run the two queries:

languages/lang[(text()='en_GB.UTF-8') and (@percentage>50)]|languages/lang[(text()='en_GB') and (@percentage>50)]|languages/lang[(text()='en.UTF-8') and (@percentage>50)]|languages/lang[(text()='en') and (@percentage>50)]

languages/lang[text()='en_GB.UTF-8'][@percentage>50]|languages/lang[text()='en_GB'][@percentage>50]|languages/lang[text()='en.UTF-8'][@percentage>50]|languages/lang[text()='en'][@percentage>50]

on the XML below, they should return the same results. In the second query, the second predicate should filter the results of the first. However, they don’t: the first query returns no results, whereas the second returns the <lang percentage="100">es</lang> element.

I suspect the unions above and most of the XML in the reproducer below are irrelevant, but I’m filing this quickly while working on something else, so haven’t taken the time to trim the reproducer down.

The straightforward workaround is to combine the predicates (as in query 1), and that’s what I’ll do in gnome-software, so I apologise but I don’t plan to come back to this issue. There should be enough information here for someone else to pick it up at some point though.

generated xb data not usable in some locales

I'm partly upstreaming this from a gnome-software bug:
https://gitlab.gnome.org/GNOME/gnome-software/-/issues/2443

This is on Fedora 39 with libxmlb 0.3.15-1. Downgrade to the 0.3.14-1 doesn't seem to change anything.

where the user doesn't see Flatpak apps when runs gnome-software in some locales, while they are shown with for example en_US.utf8 locale.

We did some investigation in the bug and the xb-tool is able to reproduce the problem with failed queries, even though the query itself does not contain anything locale-specific.

You can fast-forward to this comment, though it would be good to read the whole bug, maybe. The user did not change the locale in the system, thus the things should just work, right?

Do you think there is a reason why the queries can fail, depending with which locale the gnome-software generates the xmlb blobs/files?

Fix function doc for xb_builder_source_add_simple_adapter()

The documentation is exactly the same as xb_builder_source_add_adapter()

 * @self: a #XbBuilderSource
 * @content_types: mimetypes, e.g. `application/x-desktop,application/gzip`
 * @func: a callback, or %NULL
 * @user_data: user pointer to pass to @func, or %NULL
 * @user_data_free: a function which gets called to free @user_data, or %NULL
 *
 * Adds a function that can be used to convert streams loaded with
 * xb_builder_source_load_xml().

Now that they differ in a flag arg (is_simple), both descriptions should be updated to reflect this.

Non-reproducible GUID in compressed XML files

Hello Richard Hughes,

While working on the “reproducible builds” effort 1, I have noticed that the content of the GUID field of the converted, compressed XML files cannot be recreated in any way.

The function xb_builder_import_node (which is called by as_cache_components_to_internal_xb in appstream) uses the address of a pointer for the creation of the GUID field 2.
See the currents tests 3 for Debian, and the investigations I previously did 4.

Steps to reproduce:

Run appstreamcli refresh-cache
Notice that the content of /var/cache/app-info/cache/C-os-catalog.xb changes only in the GUID field (using xb-tool)
If the file C-local-metainfo.xb is deleted before running appstreamcli refresh-cache, it will also differ only in the GUID field.

The tool xb-tool does not call xb_builder_import_node, so I cannot give an example that only uses libxmlb.

My goal:

Create a live image that can be reproduced bit-by-bit.

Proposal:

For a drop-in-replacement of the GUID field (128 bits) I see several easy alternatives:
1. Zero-out the field and not use it (which is probably not desired)
1. Calculate the MD5 checksum (which is also 128 bits) of the compressed bitstream before writing to disk
1. Generate a truly random UUID, with uuid_generate_random from libuuid (which I can de-randomize using my LD_PRELOAD-hack)
Alternatively (but that requires more bits), something similar to GNU_BUILD_ID can be used
If you are interested, I can provide you with a patch.

With kind regards,
Roland Clobus

why disable msvc?

Hi,

I'm trying to build this project in Windows, with MSVC, but the code disabled it.

libxmlb/meson.build

Lines 89 to 91 in 4393955

 if cc.get_id() == 'msvc' 

 error('MSVC is not supported as it does not support __attribute__((cleanup))') 

 endif

I checked the code and found that __attribute__((cleanup)) is not used in the source code, so why disable msvc?

XbSilo-CRITICAL **: strtab+offset is outside the data range for 12

I do not know what I've missing here, but I surely do something miss here. When I:

mkdir -p /tmp/share/app-info/xmls
cp /usr/share/app-info/xmls/fedora-popular.xml /tmp/share/app-info/xmls
compile the attached xml-parser.c.txt (the first line contains a command to compile & run it) and run it, then I get:

process:66515): XbSilo-CRITICAL **: 18:03:12.609: strtab+offset is outside the data range for 12

** (process:66515): WARNING **: 18:03:12.609: Failed to compile data: strtab_ntags incorrect

I do not know why it does that, but when I comment out the "RemoveNonMergeComponents" fixup (beginning at line 142), then it is happy.

This is with the current sources, at commit 3f25c84.

When I keep the /tmp/share/app-info/xmls empty, then I get a crash:

Program received signal SIGSEGV, Segmentation fault.
0x00007ffff7fa952a in xb_silo_get_node_element (self=0x4178e0, n=0x0) at ../src/xb-silo.c:438

An interesting observation, when I change the path, like to /tmp/xxx, then the runtime warning has a different number.

For the code itself: I want to read all components, which have the merge attribute and discard (ignore) everything else. I want also the opposite, read only components without the merge attribute. Maybe I do something wrong, or the XB_BUILDER_NODE_FLAG_IGNORE flag misbehaves, or anything else.

reserved identifier violation

I would like to point out that identifiers like “__LIBXMLB_H_INSIDE__” and “_XbBuilderClass” do eventually not fit to the expected naming convention of the C language standard.

Include build documentation

As reported in fwupd/fwupd#914 it isn't obvious that the steps to build are:

# meson build
# ninja -C build
# ninja -C build install
# ldconfig

These should be included in README.md to make it clearer when installing from a non-packaged version how to use this project.

Possibly inline a number of internals

It looks like LTO isn't doing such a great job of interning a number of things that I think are worth seeing inlined. Not because these functions themselves show up on profiles a whole lot (but they do show up) but instead that the reduce the amount of optimization that can surround them in tight loops.

These aren't any panacea or anything, but it does help ensure that the compiler knows what is going on across the function call and perhaps reorder things a bit more.

Hoist a bunch of xb-opcode.c into xb-opcode-private.h
Hoist a bunch (all) of xb-silo-node.c into xb-silo-node-private.h

And of course bunch of that can be const and G_GNUC_PURE in the process.

The structures here are already exposed in the private headers and so static inlineing the helpers that are used everywhere makes sense to me.

While I'm here, I also wondered about perhaps changing how xb_machine does GError. Turns out we hit the failure path in xb_machine_check_two_args() quite a bit. Is it essential to propagate opcode level error tracking?

Anyway, wanted to get your thoughts before I spend too much time on it.

fwupd conflict with `gwyddion` package

A downstream bug report in Ubuntu indicated that silos were failing to compile. After debugging the issue it came down to the user installing the gwyddion package.

fwupd[920251]: 11:13:34:0743 FuQuirks failed to build silo: failed to compile /usr/share/fwupd/quirks.d/tpm.quirk:ctime=1601481168.750206: cannot process content type application/x-stmprg-spm

This package, gwyddion installs a mime type specifically:

<!-- From module stmprg.c -->
