gh-114572: Fix locking in cert_store_stats and get_ca_certs by davidben · Pull Request #114573 · python/cpython

davidben · 2024-01-25T23:04:35Z

cert_store_stats and get_ca_certs query the SSLContext's X509_STORE with X509_STORE_get0_objects, but reading the result requires a lock. See openssl/openssl#23224 for details.

Instead, use X509_STORE_get1_objects, newly added in that PR. X509_STORE_get1_objects does not exist in current OpenSSLs, but we can polyfill it with X509_STORE_lock and X509_STORE_unlock.

Thanks for submitting this David!

This change feels newsworthy, can we get a news entry for this change using blurb?

I've reviewed the approach and I'm happy with it but will need a core developers' review before it can be merged.

Noting this is a faithful backport of openssl/openssl@08cecb4

From looking at all the OpenSSL docs this appears to be correct? I'm less versed with the OpenSSL API than the submitter :)

sethmlarson · 2024-01-26T21:22:10Z

Also noting that this PR can't be directly backported, some of the functions it relies on are only in OpenSSL 1.1.0+ (specifically the locking functions).

Done.

This will be needed for python/cpython#114573. Along the way, document the various functions that expose "query from X509_STORE". Most of them unfortunately leak the weird caching thing that hash_dir does, as well as OpenSSL's generally poor handling of issuers with the same name and CRL lookup, but I don't think it's really worth trying to unexport these APIs.

Anything left to do on my end on this one?

@sethmlarson This LGTM, wasn't sure if there was anything you wanted to verify before merging.

@alex I think this is good to go! Thank you :)

gcc 9.5 has a bug https://gcc.gnu.org/bugzilla/show_bug.cgi?id=95189 that has not been backported. Essentially, the compiler will falsely reason that it's comparing a string and optimise out everything behind a null-character. Dropping static const removes optimisation options for the compiler. In my tests, gcc 9.5 now emits a direct memcmp instead of attempting any optimisations. Add X509_STORE_get1_objects This will be needed for python/cpython#114573. Along the way, document the various functions that expose "query from X509_STORE". Most of them unfortunately leak the weird caching thing that hash_dir does, as well as OpenSSL's generally poor handling of issuers with the same name and CRL lookup, but I don't think it's really worth trying to unexport these APIs.
