This cannot be handled using symbol versioning alone. We have to resort to the same technique used by stat. I.e.: - assign a non-default version to [gs]etcontext so that you cannot link against it anymore (see atexit for how to do this) - create new __x[sg]etcontent interfaces which take the usual interfaces plus a version number - add new [sg]etcontext interfaces into libc_nonshared.a which call the __x[sg]etcontent interfaces with the appropriate version argument This still isn't solving the problem completely. Is there some padding space in the old structure? If yes, use it for a version number. If there is no room, add such a field to the new structure somewhere. The code then must be changed to check for this value so that references are not passed incorrectly. -- What |Removed |Added ---------------------------------------------------------------------------- Status|NEW |WAITING http://sourceware.org/bugzilla/show_bug.cgi?id=6816 ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.
