tbordaz commented 4 months ago @firstyear I like this change to use slapi_pblock_set_flag_operation_notes but it is a different change from checking the attribute against the schema. IMHO it makes review more complex and I would prefer a separate ticket. In addition I think it is a wrong use here. slapi_pblock_set does set the value while slapi_pblock_set_flag_operation_notes do a OR. Better to check the others places where you used slapi_pblock_set_flag_operation_notes that the OR was intended
tbordaz commented 4 months ago Just realized that you also created slapi_pblock_set_operation_notes that can be used here

Bug Description: 389 Should assert that all attributes in a filter
are present and valid in schema. If there are attributes in a filter
that are not in schema, this can lead to DOS due to fall-back to
un-indexed scans, and it also can mask and cover-up application and
development issues with queries. For example, the referenced case was
caused by IPA mistakenly searching an attribute that can never be
satisfied by ACI/filter. If we warned or rejected filters in this case
we would have quickly communicated to the developer that they had caused
a mistake - feedback, being a vital component of psychology and usability
theory.

This should optionally be allowed to be disabled, due to some sites that
use things like extensibleObject that by nature, bypass and violate schema
checks.

Fix Description: TODO

This is currently only a partial start to implement the test framework to
demonstrate that we have a working filter check with our schema.

@spichugi yes that's expected, @tbordaz has answered my question (This code is not in a mergeable state yet).

@tbordaz As a follow up, can you check this to see if my approach to checking if the filter attributes are in schema seems reasonable and correct? I've tried to make this a cmocka test so that we can be more confident in the code compare to just a lib389 test - it's also a bit easier to debug too. Would like to know your thoughts on if this seems reasonable so far. :)

Why not using attr_syntax_get_by_name_locking_optional(name, FALSE, 0)

I have a bit concern about locking the syntax tables here. I could increase contention on it.
Do we really need the lock for a lookup ?
