[LTP] [PATCH v3 1/2] doc: generate CVE catalog documentation

[LTP] [PATCH v3 1/2] doc: generate CVE catalog documentation

[Sachin Sant]

Add a Sphinx builder hook to parse runtest/cve and generate a
comprehensive CVE catalog in a single documentation file.

The implementation:
- Parses runtest/cve to extract CVE IDs, test names, and options
- Generates a single CVE catalog file (_static/cves.rst) containing:
  * Total CVE count
  * All CVEs sorted in descending order (newest first)
  * For each CVE:
    - Links to CVE MITRE database
    - Cross-references to test catalog entries
    - Test command details and options
    - Vulnerability description
- Integrates CVE catalog into main documentation index

Closes: https://github.com/linux-test-project/ltp/issues/1254

V3 changes:
- CVEs sorted in descending order
- append test name to CVE id : CVE (Test Name)
- Separate page for CVE catalog
- Link cve testcases to Test catalog entry
- v2 link https://lore.kernel.org/ltp/0df5f75d-eb8f-428e-9888-bb7a90a6b1a4@linux.ibm.com/

V2 changes:
- Replace Fixes tag by Closes
- V1 link https://lore.kernel.org/ltp/20260423105304.59788-1-sachinp@linux.ibm.com/T/#u

[LTP] [PATCH 2/2] doc: Rename statistics page to 'Supported syscalls'

[Sachin Sant]

Rename the documentation page from 'Statistics' to 'Supported syscalls'
to better reflect its content, which focuses on syscall coverage.

- Renamed doc/users/stats.rst to doc/users/supported_syscalls.rst
- Updated page title and description
- Updated references in doc/index.rst
- Updated spelling exclusion pattern in doc/conf.py
- Renamed function definition from generate_syscalls_stats to
  generate_supported_syscalls
- Updated app.connect() call to use the new function name

Hi Sachin,

Both patches look good to me.

One minor note for future reference: the suppress_warnings entry added
in patch 1 silences all autosectionlabel warnings globally, not just
those from kernel-doc content as the comment implies. This is pre-existing
context and does not block this series.

The idea is good, a few comments on the implementation tho:

Please use just 'cve.rst' instead of 'cves.rst'. The plural is not
providing any info here.

Do we need a regexp for this? The runtest file is well defining the
following structure:

  <cve-id> <binary> <arg0> <arg1> ..

We only need to split lines which are not starting with # char,
considering space as separator.

All this text is redundant and occupying space for no reason.
Also I'm not sure about this approach, now we have tests list duplication
inside the documentation.

What about generating only a simple reference table? There are only 3
information we need: CVE ID, test binary, year.

| ID | Test name | Year |
-------------------------
| .. |    ..     |  ..  |

etc..

There's no need to have a direct link to the CVE, since we already pointing
CVE to the Test catalog anyway.

Do we need year in a column at all? If we like separating by year, we can make
more tables each being just for a particular year.

OTOH it would not harm (people interested at CVE will have look mostly on this
page, that would save them one click.

Kind regards,
Petr

Sure, will change the name.

Okay. Do we need year in the column since the CVE name also has year.
For cve.rst, I implemented the same logic as tests.rst.

A separate entry for CVE catalog.
Once a user clicks on this option it will expand with a list of 
individual CVE pages
in the left pane. Each entry follows the following format

<CVE ID> ( <Test Name> )

Based on review comments how should the page look like?

A separate entry for CVE catalog.
Once a user clicks on this option it will display the CVE list in 
tabular format
sorted by year. The table will follow (assuming Year to be retained)

| ID | Test name | Year |
-------------------------
| .. |    ..     |  ..  |


Test name will point to an entry in Test catalog.
No individual pages required for each CVE.

Can you confirm?
> There's no need to have a direct link to the CVE, since we already pointing
Okay. I can make this change. I followed the earlier

Thanks for the review.

No we dont need the year as Petr mentioned.
