Bernhard Reutner-Fischer	86a7f18f21	*: Switch to POSIX utmpx API UTMP is SVID legacy, UTMPX is mandated by POSIX. Glibc and uClibc have identical layout of UTMP and UTMPX, both of these libc treat _PATH_UTMPX as _PATH_UTMP so from a user-perspective nothing changes except the names of the API entrypoints.

Kevin Wallace	782ee2aa0e	libbb/loop: don't try to re-use existing loop device loopinfo.lo_file_name is not enough to uniquely identify a file on a system with multiple mount namespaces. We could conceivably change this to dedup on (lo_rdevice, lo_inode), but, as the comment above the deleted code notes, this whole approach of reusing devices is racy anyway, so it seems better to stop doing it entirely.

Bartosz Golaszewski	8d75d794ea	libbb: use sendfile() to copy data between file descriptors Busybox already uses sendfile in httpd.

Denys Vlasenko	04c1417602	libbb: use ARG_MAX for bb_arg_max() only if it's 60k+ 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>	2014-11-26 15:17:59 +01:00
