kib 2009-10-10 15:27:10 UTC FreeBSD src repository Modified files: libexec/rtld-elf rtld.c Log: SVN rev 197931 on 2009-10-10 15:27:10Z by kib Calculate relocation base for the main object, and apply the relocation adjustment for all virtual addresses encoded into the ELF structures of it. PIE binary could and should be loaded at non-zero mapbase. For sym_zero pseudosymbol used as a return value from find_symdef() for undefined weak symbols, st_value also should be adjusted, since _rtld_bind corrects symbol values by relocbase.
