Is there a good description of ELF shared library symbol versioning best practices somewhere? In particular, under what conditions do you need to create a new section in the versioning file given to the linker's --version-script option when new symbols are added? And what do you do if you've done it wrong? For example, in libkeyutils, I added a couple of symbols to KEYUTILS_1.4 when I should perhaps have created KEYUTILS_1.5 and added them there: http://git.kernel.org/cgit/linux/kernel/git/dhowells/keyutils.git/commit/?id=49249ce7d84a967fcdc06fbe6bf1d0cf89ac5215 I have been given a patch to move these symbols to KEYUTILS_1.5, but checking the keyctl program with "readelf -s", I see: 47: 0000000000000000 0 FUNC GLOBAL DEFAULT UND recursive_session_key_sca@KEYUTILS_1.4 (7) so I would guess applying this patch would break anything that uses this. I assumed that adding them to KEYUTILS_1.4 would be okay because nothing would've tried to use them previously because they didn't exist in any version.
