nsenter: fix parsing of -t, -S and -G options2018-05-22T15:52:51+00:00Euan Harriseuan.harris@docker.com2018-05-04T15:18:47+00:00urn:sha1:d591256a5cf9c744b9d95f7b0055dce8528a63ca
-t, -S and -G each take mandatory integer arguments. getopt32long()'s
option string syntax for this type of argument is 'c:+', however nsenter's
opt_str uses 'c+', which specifies two options 'c' and '+' which do not
take arguments. This means that giving a target PID causes nsenter to
exit and print the usage string:
# nsenter -t1 sh
nsenter: unrecognized option: 1
BusyBox v1.27.2 (2017-12-12 10:41:50 GMT) multi-call binary.
...
The long form options are also broken:
# nsenter --setuid=1000 --setgid=1000 sh
BusyBox v1.29.0.git (2018-05-04 13:56:49 UTC) multi-call binary.
...
`nsenter --target=<pid> sh` parses correctly and appears to work, but
<pid> is ignored and set to 0. This doesn't raise an error unless one
of the namespace arguments is also given:
# ./busybox_unstripped nsenter --target=42 sh
# exit
# ./busybox_unstripped nsenter -n --target=42 sh
BusyBox v1.29.0.git (2018-05-04 13:56:49 UTC) multi-call binary.
...
This has caused problems in a couple of places:

nsenter: Rename --network option to --net2018-05-22T15:52:51+00:00Euan Harriseuan.harris@docker.com2018-05-03T12:34:46+00:00urn:sha1:adb69765e52ad32608e3b56e0dd70a0510ab1b7c
In nsenter from util-linux, the long version of the -n option is
--net=<path>. BusyBox's version expects --network=<path>, so scripts
and examples written for util-linux's version cause BusyBox's version
to exit with the usage message.
Confusingly, until commit 036585a911a5f, the usage message erroneously
claimed that the long option was indeed called --net; after that commit
long options are not listed at all.
