Thinking aloud: does anyone ever use symbol overriding for anything other than glibc?
Yes. It is particularly useful for "spear fishing" debugging of lower-level interfaces in large, complex multi-process applications.
That only seems to need shallow interposition, though. In most cases, I doubt you are interested in API calls from the library self because those are probably unproblematic.
One actual case: why exp(600.0) ? Yes, the first use of overriding was shallow and libm (part of glibc). But the caller was deep within a scientific library, and the second overriding was not shallow at all. _______________________________________________ devel mailing list -- devel@lists.fedoraproject.org To unsubscribe send an email to devel-le...@lists.fedoraproject.org Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/devel@lists.fedoraproject.org
