ash,hush: ">&10" redirects to script/tty fds should not work The fact that shell has open fds to tty and/or scripts should be unobservable, if possible. In particular, if redirect tries to dup one of them via ">&script_fd", it's better to pretend that script_fd is closed, and thus redirect fails with EBADF. Fixes these two testcase failures: ash-redir/redir_to_bad_fd.tests hush-redir/redir_to_bad_fd3.tests function old new delta redirect 1018 1129 +111 setup_redirects 250 359 +109 readtoken1 2651 2655 +4 cmdloop 185 187 +2 changepath 194 195 +1 save_fd_on_redirect 203 194 -9 evaltree 501 484 -17 ------------------------------------------------------------------------------ (add/remove: 0/0 grow/shrink: 5/2 up/down: 227/-26) Total: 201 bytes text data bss dec hex filename 914553 485 6848 921886 e111e busybox_old 914754 485 6848 922087 e11e7 busybox_unstripped Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
