-Subject: [PATCH] curl: allow overriding default CA certificate file
-
-Similar to curl, --cacert can now be used in cve-check-tool and
-cve-check-update to override the default CA certificate file. Useful
-in cases where the system default is unsuitable (for example,
-out-dated) or broken (as in OE's current native libcurl, which embeds
-a path string from one build host and then uses it on another although
-the right path may have become something different).
-
-Upstream-Status: Submitted [https://github.com/ikeydoherty/cve-check-tool/pull/45]
-
-Signed-off-by: Patrick Ohly <patrick.ohly@intel.com>
-
-
-Took Patrick Ohlys original patch from meta-security-isafw, rebased
-on top of other patches.

-Subject: [PATCH] update: Compare computed vs expected sha256 digit string
- ignoring case
-
-We produce sha256 digest string using %x snprintf()
-qualifier for each byte of digest which uses alphabetic
-characters from "a" to "f" in lower case to represent
-integer values from 10 to 15.
-
-Previously all of the NVD META files supply sha256
-digest string for corresponding XML file in lower case.
-
-However due to some reason this changed recently to
-provide digest digits in upper case causing fetched
-data consistency checks to fail. This prevents database
-from being updated periodically.
-
-While commit c4f6e94 (update: Do not treat sha256 failure
-as fatal if requested) adds useful option to skip
-digest validation at all and thus provides workaround for
-this situation, it might be unacceptable for some
-deployments where we need to ensure that downloaded
-data is consistent before start parsing it and update
-SQLite database.
-
-Use strcasecmp() to compare two digest strings case
-insensitively and addressing this case.

-
-malloc_trim is gnu specific and not all libc
-implement it, threfore write a configure check
-to poke for it first and use the define to

-Helps in compiling on musl based systems
