fsck: fix incorrect handling of child exit
In commit
c4fb8c6a - fsck: do not use statics
not only statics were changed but also a couple of
statics-unrelated changes were made.
This included the handling of the child termination status
as follows:
- if (WIFEXITED(status))
- status = WEXITSTATUS(status);
- else if (WIFSIGNALED(status)) {
+ status = WEXITSTATUS(status);
+ if (WIFSIGNALED(status)) {
This is wrong, should have used a different variable to hold exit code.

nsenter: fix parsing of -t, -S and -G options
-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

In nsenter from util-linux, the long version of the -n option is

Confusingly, until commit

expand: Fix buffer overflow in expandmeta
The native version of expandmeta allocates a buffer that may be
overrun for two reasons. First of all the size is 1 byte too small
but this is normally hidden because the minimum size is rounded
up to 2048 bytes. Secondly, if the directory level is deep enough,
any buffer can be overrun.
This patch fixes both problems by calling realloc when necessary.

If applets/applet_tables is created first during applets_dir then it will

As a result include/applet_tables.h is created again. This time while other
