2016-08-26udhcpc: Unconditionally call deconfig script, not only if lease is activePeter Korsgaard
The udhcpc script may be used to setup fallback configuration (E.G. IPv4LL, fixed IP address, ..) that also needs to be cleaned up on release (E.G. when SIGUSR2 is called or on shutdown with -R), so unconditionally call deconfig.

2016-08-20hush: do not leak script fds into NOEXEC childrenDenys Vlasenko
We set all opened script fds to CLOEXEC, thus making then go away after fork+exec. Unfortunately, CLOFORK does not exist. NOEXEC children will still see those fds open. For one, "ls" applet is NOEXEC. Therefore running "ls -l /proc/self/fd" in a script from standalone shell shows this: lrwx------ 1 root root 64 Aug 20 15:17 0 -> /dev/pts/3 lrwx------ 1 root root 64 Aug 20 15:17 1 -> /dev/pts/3 lrwx------ 1 root root 64 Aug 20 15:17 2 -> /dev/pts/3 lr-x------ 1 root root 64 Aug 20 15:17 3 -> /path/to/top/level/script lr-x------ 1 root root 64 Aug 20 15:17 4 -> /path/to/sourced/SCRIPT1 ... with as many open fds as there are ". SCRIPTn" nest levels. Fix it by closing these fds after fork (only for NOEXEC children). 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>

2016-08-15gzip: fix compression level bug. Closes 9131Natanael Copa
fix broken logic to get the gzip_level_config value from options -1 to -9. This fixes an off-by-one bug that caused gzip -9 output bigger files than the other compression levels. It fixes so that compression level 1 to 3 are actually mapped to level 4 as comments say. It also fixes that levels -4 to -9 is mapped to correct level and avoids out-of-bounds access.

2016-08-01ntpd: respond only to client and symmetric active packetsMiroslav Lichvar
The busybox NTP implementation doesn't check the NTP mode of packets received on the server port and responds to any packet with the right size. This includes responses from another NTP server. An attacker can send a packet with a spoofed source address in order to create an infinite loop of responses between two busybox NTP servers. Adding more packets to the loop increases the traffic between the servers until one of them has a fully loaded CPU and/or network.
