2018-01-10ash: make ${v:N:M} more robust for very large M by clamping to MIN/MAX_INTDenys Vlasenko
Before this patch, "${v:2:0x100000001}" = "${v:2:1}", and similarly, constructs like "${v:2:9999999999}" may give wrong result due to int overflows. function old new delta substr_atoi - 43 +43 Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

2017-10-31grep: skip grepping symlinks to directoriesJames Clarke
When grep is passed -r, recursive_action will treat any symlinks to directories not in the root as normal files, since it lstat's them and is therefore told they are not directories. However, file_action_grep will still try to fopen and read from them to see whether they match, which varies in behaviour across platforms. Linux will give EISDIR and thus grep will not find any matching lines, but FreeBSD will give the raw contents of the directory itself, which may match the given pattern. Also, if grep is passed -c, it will even print a count for these symlinks, even on Linux. Since this recursive_action behaviour is required for the correct functioning of other applets, such as tar, grep should handle this special case and skip any such symlinks. function old new delta file_action_grep 80 161 +81 Signed-off-by: James Clarke <jrtc27@jrtc27.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

2017-10-30udp_io, traceroute: Standardise IPv6 PKTINFO handling to be portableJames Clarke
The current standard (RFC 3542) is for IPV6_RECVPKTINFO to be given to setsockopt, and IPV6_PKTINFO to be used as the packet type. Previously, RFC 2292 required IPV6_PKTINFO to be used for both, but RFC 3542 re-purposed IPV6_PKTINFO when given to setsockopt. The special Linux-specific IPV6_2292PKTINFO has the same semantics as IPV6_PKTINFO in RFC 2292, but was introduced at the same time as IPV6_RECVPKTINFO. Therefore, if we have IPV6_RECVPKTINFO available, we can use the RFC 3542 style, and if not, we assume that only the RFC 2292 API is available, using IPV6_PKTINFO for both.

2017-10-30df: Use statvfs instead of non-standard statfsJames Clarke
Platforms differ on what their implementations of statfs include. Importantly, FreeBSD's does not include a f_frsize member inside struct statfs. However, statvfs is specified by POSIX and includes everything we need, so we can just use that instead.
