89b1e287f7 find_user() in process.c does an unbounded copy into a destination 
buffer that is smaller in size than the source buffer.

also, there is no guarantee that any of the string components of
the request packet are null terminated.

in some cases, not all elements of the response buffer are
explicitly set. specifically pad and addr. a talk client can spy to
see which host is talking to which host by sending out regular
packets, to which talkd responds without clearing the addr element.

9754fa4d8e Make immediate binding work again by actually implementing 
_rtld_relocate_plt_objects(). Note that this is for i386 only;
any efforts to make it work on other platforms are left to
those who are using them...

60330f4a69 The sense of the SHN_ABS test has always been reversed. Fortunately nobody

8f7fa0cfde Put back the lazy binding. For some bizarre reason, the linker occasionally 
does not create a PLT entry for a symbol, so we test st_value!=0 to see
whether we can do a PLT fixup.

a18c524897 Figure out obj->pltrel(a) after the dynamic section is parsed, so the relative 
order of DT_PLTREL and DT_JMPREL is irrelevant.  Removes the need for yet
another weird #ifdef.
Also, be slightly more careful with the rel(a)lim trimming.

a05a73b5b6 revert previous. wtmp{,x} entries need not be \0-terminated, so 
strncpy is more proper.
