Hi all, while investigating ways to access the auxillary vector, I found that we currently don't deal correctly with struct ps_strings in 32bit compat. This structure is placed by the kernel into the initial stack and referenced in userland by __ps_strings. It is used by setproctitle(3) and therefore e.g. by programs that want to include a status report in the ps(1) output. This naturally works only by chance, if at all in compat32. How do we want to deal with it?
Variant 1: Leave it as broken. It should be said that having reliable ps_strings could speed up ld.elf_so a bit. Variant 2: Introduce two methods for obtaining and setting ps_strings of a specific process and hook those into the normal exec mechanism. This would in theory allow emulations pretty arbitrary data structures. Other options that are better? Joerg
