9c8e94bc0a ash: fail if 'shift' operand is out of range
If the numeric argument passed to ash's 'shift' built-in is greater than
'$#' the command performs no operation and exits successfully. It should
return a non-zero exit code instead:

This is consistent with bash and hush.

c6f213ade4 unzip: fix content listing and filtering when -j is used
Original Info-ZIP's unzip uses unstripped filenames
while doing content listing and filtering, i.e.
 - in content listing mode -j is ignored completely
 - filtering is applied to non-stripped names, -j
   takes effect first while extracting the files

997ad2c64a strips path
components a little bit too early resulting in behavior
deviations.

Fix it by doing stripping after listing/filtering.

p.s. Info-ZIP's unzip behavior is the same as
     that of tar in --strip-components=NUM mode

6bcc2c0f6c grep: skip grepping symlinks to directories
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.

518fb3ba19 udp_io, traceroute: Standardise IPv6 PKTINFO handling to be portable
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.

d1535216ca df: Use statvfs instead of non-standard statfs
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.

ecce3a1999 iproute/iprule: support toolchains without RTA_TABLE routing attribute
iproute.c: In function 'print_route':
 iproute.c:85:9: error: 'RTA_TABLE' undeclared (first use in this function)
 iproute.c:85:9: note: each undeclared identifier is reported only once for each function it appears in
 iproute.c: In function 'iproute_modify':
 iproute.c:467:36: error: 'RTA_TABLE' undeclared (first use in this function)

Fix it by partially #ifdef'ing the code added in b42107f215

0402cb32df bunzip2: fix runCnt overflow from bug 10431
This particular corrupted file can be dealth with by using "unsigned".
If there will be cases where it genuinely overflows, there is a disabled
code to deal with that too.
