A do_vulnerability() which can run CVE tasks plugged by function variables
VULNFUNC_SCAN_CVE, VULNFUNC_JUDGE_CVE and VULNFUNC_REPORT_CVE.
Variable VULNFUNC_SCAN_CVE is used for the purpose of CVE search based on
CPE (Common Platform Enumeration).
A do_vulnerability() decides two CVE statements 'Patched' or 'Unpatched'
which are coming from the result of CVE patch searching.
However, do_vulnerability() allows VULNFUNC_JUDGE_CVE to change statements.
Then plugged function can check CVE statement moreover by using private
knowledge information. Now plugged functions are only called for 'Unpatched'.
Variable VULNFUNC_REPORT_CVE is used to generate each task's reports.
Here are also implemented following CVE functions.
cve_assemble_cpe()
Assemble CPE (Common Platform Enumeration) from recipe variables.
Assembled CPE list is tossed to functions in VULNFUNC_SCAN_CVE.
cve_number_sort()
Sort CVE with 11 digits CVE number (If shorter than 11, fill with zero).
This can be formatted reports with sorted CVE entries within per package.
cve_make_git_commitlist()
Track accumulated git repository commits from base revision to HEAD and
search CVE number in commit log to gather CVE corresponding commits.
Gathered commits are compared with CVE number found by VULNFUNC_SCAN_CVE
and judge 'Patched' or 'Unpatched'.
For example, Linux kernel 5.2 which has been introduced in "linux-yocto:
introduce 5.2 recipes" with commit IDs in SRCREV_machine_${MACHINE}s.
If set those SRCREV commit IDs to CVE_SRCREV_${MACHINE}s, this function
will search CVE kernel commit from CVE_SRCREV to HEAD.
cve_make_patchlist()
Find CVE patches from every layer SRC_URI directory.
Gathered patches are compared with CVE number found by VULNFUNC_SCAN_CVE
and judge 'Patched' or 'Unpatched'.
This function do the same things as get_patches_cves() which is implemented
at meta/cve-check.bbclass.
cve_trim_upon_dirs()
Trim upper directory path than layer directory to make formatted reports.
This is used to specify patch or git repository containing places.
Finally vulnerability task publishes per package "vulnerability.summary"
and "vulnerability.patchlist" reports.
First one is reporting CVE number list and their judgement, second one is
reporting only about 'Patched' with their patch or commit information to
be found out.

To: openembedded-core
A rootfs post command function vuln_cve_make_manifests() generates
some manifests about CVE_REPORTS list variable where files are generated
in per package task. A vuln_cve_make_manifests() gather these files about
installed packages in image from sstate directory to deploy manifest files
specified in CVE_MANIFEST to CVE_MANIFEST_DIR.
If CVE_MANIFEST_POPULATES is valid, vuln_cve_make_manifests() populate
manifest with "No vulnerability task support packages" which are installed
but not inherit vuln-cve and populate package contents with name, version
and installed package names.
And for the image recipe itself, prepare VULNFUNC_IMAGE_CLASS plugin which
may append summary header as image manifest such as CVE database freshness
which is inserted at the top of manifest files.
