2017-01-24tls: add 2nd cipher_id, TLS_RSA_WITH_AES_128_CBC_SHA, so far it doesn't workDenys Vlasenko
Good news that TLS_RSA_WITH_AES_256_CBC_SHA256 still works with new code ;) This change adds inevitable extension to have different sized hashes and AES key sizes. In libbb, md5_end() and shaX_end() are extended to return result size instead of void - this helps *a lot* in tls (the cost is ~5 bytes per _end() function).

2016-11-24lineedit: fix handling of repeating Alt-b, Alt-f, Alt-d, Alt-BackspaceRostislav Skudnov
These key combinations should repeat correctly when the keys are pressed and held. Before this change, they do this erratically - many repeats are "eaten" because they are treated as unrecognized ESC seqs: ESC 0x7f is treated by Alt+baskspace, but ESC 0x7f ESC 0x7f ESC 0x7f is unrecognized. Escape sequences corresponding to these key combinations are moved from read_line_input to lineedit_read_key. Also, these key sequences are now enabled regardless of whether FEATURE_EDITING_VI is set, since Vim does not actually support these key combinations, but they are present in readline library. function old new delta static.esccmds 93 103 +10 read_line_input 3737 3687 -50 Signed-off-by: Rostislav Skudnov <rostislav@tuxera.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

2016-08-19hush: fix a bug in FEATURE_SH_STANDALONE=y config. Closes 9186Denys Vlasenko
Run this in a "sh SCRIPT": sha256sum /dev/null echo END sha256sum is a NOEXEC applet. It runs in a forked child. Then child exit()s. By this time, entire script is read, and buffered in a FILE object from fopen("SCRIPT"). But fgetc() did not consume entire input. exit() lseeks back by -9 bytes, from <eof> to 'e' in 'echo'. (this may be libc-specific). This change of fd position *is shared with the parent*! Now parent can read more, and it thinks there is another "echo END". End result: two "echo END"s are run. Fix this by _exit()ing instead. Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
