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.

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 :)

You are in 'detached HEAD' state. You can look around, make experimental
changes and commit them, and you can discard any commits you make in this
state without impacting any branches by switching back to a branch.

If you want to create a new branch to retain commits you create, you may
do so (now or later) by using -c with the switch command. Example:

  git switch -c <new-branch-name>

Or undo this operation with:

  git switch -

Turn off this advice by setting config variable advice.detachedHead to false

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.

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.

…thon#114573) * pythongh-114572: Fix locking in cert_store_stats and get_ca_certs 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. * Work around const-correctness problem * Add missing X509_STORE_get1_objects failure check * Add blurb
