Implement sk_find manually. glibc inlines bsearch, so CFI does observe the function pointer mishap. Binary search is easy enough, aside from thinking through the edge case at the end, so just implement it by hand. As a bonus, it actually gives O(lg N) behavior. sk_*_find needs to return the *first* match, while bsearch does not promise a particular one. sk_find thus performs a fixup step to find the first one, but this is linear in the number of matching elements. Instead, the binary search should take this into account. This still leaves qsort, but it's not inlined, so hopefully we can leave it alone.

BoringSSL is a fork of OpenSSL that is designed to meet Google's needs.
Although BoringSSL is an open source project, it is not intended for general use, as OpenSSL is. We don't recommend that third parties depend upon it. Doing so is likely to be frustrating because there are no guarantees of API or ABI stability.
Programs ship their own copies of BoringSSL when they use it and we update everything as needed when deciding to make API changes. This allows us to mostly avoid compromises in the name of compatibility. It works for us, but it may not work for you.
BoringSSL arose because Google used OpenSSL for many years in various ways and, over time, built up a large number of patches that were maintained while tracking upstream OpenSSL. As Google's product portfolio became more complex, more copies of OpenSSL sprung up and the effort involved in maintaining all these patches in multiple places was growing steadily.
Currently BoringSSL is the SSL library in Chrome/Chromium, Android (but it's not part of the NDK) and a number of other apps/programs.
