applets/install: don't try to install nothing
Commit
952d5a6024e7 (applets/install: accept more than one install
option) changed the way we handle install options: before that commit, a
missing install type would mean to install nothing; after, we would
iterate over options, so we would never notice there was a mising
option.
Fix that by introducing an explicit --none option to specify to install
nothing.

Upstream commit:
Date: Sun, 25 Mar 2018 16:38:00 +0800
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.

build system: fix parallel building issue
The files generated by the include/config/MARKER target are in the

If applets/applet_tables is created first during applets_dir then it will
be created again later as part of $(busybox-dirs).
As a result include/applet_tables.h is created again. This time while other

Let applets_dir depend on include/config/MARKER to avoid this particular

parser: Fix parameter expansion inside inner double quotes
The parsing of parameter expansion inside inner double quotes
breaks because we never look for ENDVAR while innerdq is true.

This patch fixes it by pushing the syntax stack if innerdq is
true and we enter a new parameter expansion.
This patch also fixes a corner case where a bad substitution error

parser: Fix single-quoted patterns in here-documents
The script
x=*
cat <<- EOF
${x#'*'}
EOF
prints * instead of nothing as it should. The problem is that
when we're in sqsyntax context in a here-document, we won't add
CTLESC as we should. This patch fixes it:

ash: parser: Add syntax stack for recursive parsing
This closes 10821.
Upstream patch:

parser: Add syntax stack for recursive parsing
Without a stack of syntaxes we cannot correctly these two cases
together:
"${a#'$$'}"
"${a#"${b-'$$'}"}"
A recursive parser also helps in some other corner cases such
as nested arithmetic expansion with paratheses.
This patch adds a syntax stack allocated from the stack using
alloca. As a side-effect this allows us to remove the naked
backslashes for patterns within double-quotes, which means that
EXP_QPAT also has to go.
This patch also fixes removes any backslashes that precede right
braces when they are present within a parameter expansion context,
and backslashes that precede double quotes within inner double
quotes inside a parameter expansion in a here-document context.
The idea of a recursive parser is based on a patch by Harald van
Dijk.

sed: prevent overflow of length from bb_get_chunk_from_file
This fragment did not work right:
temp = bb_get_chunk_from_file(fp, &len);
if (temp) {
/* len > 0 here, it's ok to do temp[len-1] */
char c = temp[len-1];
With "int len" _sign-extending_, temp[len-1] can refer to a wrong location
if len > 0x7fffffff.
