2016-10-24ash: return exit status of nofork appletsRon Yorston
The commit 'ash: eval: Return status in eval functions' changed how exit status is handled in eval functions. The case of nofork applets was missed, resulting in the incorrect status potentially being returned for nofork applets when FEATURE_SH_NOFORK is enabled.

2016-10-13telnetd: ifdef out a buggy error handling code pathDenys Vlasenko
Here, not handling the error is would just eat one input 0xff char. Correct handling would need even more corner case handling, as-is buggy handling corrupts the buffer. Since we just been told by kernel that pty is ready, EAGAIN should not be happening here anyway. function old new delta telnetd_main 1798 1785 -13 Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

2016-10-12telnetd: fix handling of short writes to ptyDenys Vlasenko
If a write to pty is short, remove_iacs() can be run on a buffer repeatedly. This, for example, can eat 0xff chars (IACs, in telnet terms). Rework the logic to handle IACs in a special "write to pty" function. function old new delta telnetd_main 1662 1750 +88 Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

2016-10-07ash: all blocks in function node copying must be SHELL_ALIGNedDenys Vlasenko
Previous commit probably introduced a bug: non-matching size calculation in size counting and actual copying caused by SHELL_ALIGN being applied differently! This won't bite if string sizes are also SHELL_ALIGNed. Thus fixing. Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

2016-10-02ash: undo "tokname hack"Denys Vlasenko
dash has tokendlist[] array to decide which tokens end lists. We store it as first byte of each tokname_array[i]. Switch to bit array, name it like dash (tokendlist), drop special 1st byte of tokname_array[i]. This brings us closer to dash, and shrinks the binary, because many more string aliasing opportunities are now open: function old new delta pstrcmp1 - 16 +16 readtoken1 2852 2858 +6 list 326 327 +1 pstrcmp 16 15 -1 tokname 45 42 -3 ------------------------------------------------------------------------------ (add/remove: 1/0 grow/shrink: 2/2 up/down: 23/-4) Total: 19 bytes text data bss dec hex filename 943556 916 14292 958764 ea12c busybox_old 943463 916 14292 958671 ea0cf busybox_unstripped ^^^^^^^ note this!
