2014-12-21udhcpc: account for script run timeDenys Vlasenko
Based on the following user report: I ran into an issue where I was seeing a long delay in the scripts called in udhcp_run_script. I was using an old version of OpenWrt (kamikaze) and a satellite modem. An NTP script was being called and the modem would sometimes take a long time to respond to the DNS lookup when it was offline. This delay started affecting my lease time. The lease that I would get from my satellite modem before it was online would be short: only 60 seconds. The delay with NTP and the modem would typically be about 18 seconds. This would cause the first DHCP renew request from dhcpc to be a little late. Under certain circumstances, I could even see the first DHCP renew to occur after the lease had expired! function old new delta udhcpc_main 2816 2837 +21 Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

In vi-mode lineedit tries to detect some escape sequences. After the ESC it reads the next character to check for certain values.

The performance and number of processes for a "depmod -a" with gzipped modules was abysmal. This patch adds a code path without fork, benefiting all users of xmalloc_open_zipped_read_close. "modinfo radeon.ko.gz", a single-file reader, got 30% faster. "depmod -a", which used to fork over 800 times, got 20% faster.

2014-11-27libbb: use sendfile() to copy data between file descriptorsBartosz Golaszewski
Busybox already uses sendfile in httpd. This patch proposes to use it globally to copy data between file descriptors.

2014-11-26libbb: use ARG_MAX for bb_arg_max() only if it's 60k+Denys Vlasenko
Sometimes ARG_MAX is small (like 32k) yet sysconf(_SC_ARG_MAX) is big, and people prefer using the bigger value. OTOH, with sufficiently large ARG_MAX, further wins from sysconf(_SC_ARG_MAX) being bigger are exponentially smaller: you can see 4 times fewer fork+execs when you run find, but when each execed process already takes a thousand parameters it's likely execution time is dominated by what that process does with each parameter. Thus, with this change ARG_MAX is used if it's sufficiently big, otherwise sysconf(_SC_ARG_MAX) is used. Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
