2017-03-16mount: create loop devices with LO_FLAGS_AUTOCLEAR flagDenys Vlasenko
The "autolooped" mount (mount [-oloop] IMAGE /DIR/DIR) always creates AUTOCLEARed loopdevs, so that umounting drops them (and this does not require any code in the umount userspace). This happens since circa linux-2.6.25: commit 96c5865559cee0f9cbc5173f3c949f6ce3525581 Date: Wed Feb 6 01:36:27 2008 -0800 Subject: Allow auto-destruction of loop devices IOW: in this case, umount does not have to use -d to drop the loopdev. The explicit loop mount (mount /dev/loopN /DIR/DIR) does not do this. In this case, umount without -d should not drop loopdev. Unfortunately, bbox umount currently always implies -d, this probably needs fixing. function old new delta set_loop 537 597 +60 singlemount 1101 1138 +37 losetup_main 419 432 +13 ------------------------------------------------------------------------------ (add/remove: 0/0 grow/shrink: 3/0 up/down: 110/0) Total: 110 bytes Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

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).

2017-01-23separate TLS code into a library, use in in wgetDenys Vlasenko
A new applet, ssl_client, is the TLS debug thing now. It doubles as wget's NOMMU helper. In MMU mode, wget still forks, but then directly calls TLS code, without execing. This can also be applied to sendmail/popmail (SMTPS / SMTP+starttls support) and nc --ssl (ncat, nmap's nc clone, has such option). function old new delta tls_handshake - 1691 +1691 tls_run_copy_loop - 443 +443 ssl_client_main - 128 +128 packed_usage 30978 31007 +29 wget_main 2508 2535 +27 applet_names 2553 2560 +7 ... xwrite_encrypted 360 342 -18 tls_main 2127 - -2127 ------------------------------------------------------------------------------ (add/remove: 4/1 grow/shrink: 13/8 up/down: 2351/-2195) Total: 156 bytes Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

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>

2016-02-01Fix compiling with musl's utmp stubsKylie McClain
This patch fixes compiling busybox with FEATURE_UTMP and _WTMP enabled. musl, while not really support utmp/wtmp, provides stub functions, as well as variables such as _PATH_UTMP, so that programs using utmp or wtmp can still compile fine. My reasoning for this patch is that on Exherbo, I'm currently trying to get us to be able to use the same busybox config file for both glibc and musl systems, using utmp/wtmp on systems that support it, and using the stubs on musl without needing two different configs. As of latest musl git, it provides all utmp functions needed; 1.1.12 doesn't, but I sent a patch to Rich to add the utmp{,x}name functions expected to exist, which was merged into musl upstream.
