[PATCH 0/5] exec: binfmt_misc: fix use-after-free, kill iname[BINPRM_BUF_SIZE]

[Oleg Nesterov]

Note: 5/5 depends on

        -extern int bprm_change_interp(char *interp, struct linux_binprm *bprm);
        +extern int bprm_change_interp(const char *interp, struct linux_binprm 
*bprm);

change in

        [PATCH] exec: load_script: kill the onstack interp[BINPRM_BUF_SIZE] 
array
        https://marc.info/?l=linux-kernel&m=150575251328591

I sent before.

Looks like this code was always wrong, then 948b701a607f ("binfmt_misc: add 
persistent
opened binary handler for containers") added more problems.

Oleg.
