Do the first step in removing lukemftpd from the base system. Disconnect it from the build. If you are using the FTP daemon, please consider using the port ftp/tnftpd which is the same FTP server, but newer and might have more/better functionality. This results in us providing only one ftp daemon by default. Reviewed by: bz Approved by: imp (mentor, implicit) MFC after: 3 days Silence from: obrien Approved by: re (kib), imp (mentor, implicit)

Second attempt at eliminating .text relocations in shared libraries

compiled with stack protector. Use libssp_nonshared library to pull __stack_chk_fail_local symbol into each library that needs it instead of pulling it from libc. GCC generates local calls to this function which result in absolute relocations put into position-independent code segment, making dynamic loader do extra work every time given shared library is being relocated and making affected text pages non-shareable.

Back out previous revision until better tested fix is ready.
