0dd8e45d42 ash: [EXPAND] Optimise nulonly away and just use quoted as before
Upstream commit:

    Date: Wed, 8 Oct 2014 20:09:56 +0800
    [EXPAND] Optimise nulonly away and just use quoted as before

    This patch makes a small optimisation by using the same value for
    quoted between evalvar and varvalue by eliminating nulonly and
    passing along quoted instead.

    [BUILTIN] Allow return in loop conditional to set exit status

    https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=332954

    When return is used in a loop conditional the exit status will
    be lost because we always set the exit status at the end of the
    loop to that of the last command executed in the body.

    This is counterintuitive and contrary to what most other shells do.

    This patch fixes this by always preserving the exit status of
    return when it is used in a loop conditional.

    The patch was originally written by Gerrit Pape <pape@smarden.org>.

4d12e944ea ash: [ERROR] Set exitstatus in onint
Partially backported this commit:

    Date: Thu, 2 Oct 2014 21:07:55 +0800
    [ERROR] Set exitstatus in onint

    Currently the exit status when we receive SIGINT is set in evalcommand
    which means that it doesn't always get set.  For example, if you press
    CTRL-C at the prompt of an interactive dash, the exit status is not
    set to 130 as it is in many other Bourne shells.

    This patch fixes this by moving the setting of the exit status into
    onint which also simplifies evalcommand.

7b3fa1e441 ash: [EVAL] Pass EV_TESTED into evalcmd
Upstream commit:

    Date:   Tue Aug 11 20:48:15 2009 +1000
    [EVAL] Pass EV_TESTED into evalcmd

    This patch fixes the case where the eval command is used with
    set -e and as part of a construct that should not cause the
    shell to abort, e.g., as part of the condition of an if statement.

    This is achieved by propagating the EV_TESTED flag into the
    evalstring function through evalcmd.  As this alters the prototype
    of evalcmd it is now invoked explicitly by evalbltin.  The built-in
    infrastructure has been changed to accomodate this special case.

    In order to ensure that the EXIT trap is properly executed this
    patch clears evalskip in exitshell.  This wasn't needed before
    because of the broken way evalstring worked where it always clears
    evalskip when called by minusc.

Upstream commit:

    Date: Sat, 9 Jul 2011 22:05:22 +0800
    [BUILTIN] Merge SKIPFUNC/SKIPFILE and only clear SKIPFUNC when leaving dotcmd

    Currently upon leaving a dotcmd the evalskip state is reset so
    if a continue/break statement is used within a dot script it would
    have no effect outside of the dot script.

    This is inconsistent with other shells.

    This patch is based on one by Jilles Tjoelker and only clears
    SKIPFUNC when leaving a dot script.  As a result continue/break
    will remain in effect.

    It also merges SKIPFUNC/SKIPFILE as they have no practical difference.

    Date:   Sat Oct 6 00:45:52 2007 +0800

    [MEMALLOC] Add pushstackmark

    This patch gets rid of the stack mark tracking hack by allocating a little
    bit of stack memory if we're at risk of planting a stack mark which may be
    grown later.  To do this a new function pushstackmark is added which lets
    the user pick a bigger amount to allocate since some users do that anyway
    after setting a stack mark.

3b4d04b77e ash: input: Allow two consecutive calls to pungetc
Upstream commit:

    input: Allow two consecutive calls to pungetc

    The commit ef91d3d6a4c39421fd3a391e02cd82f9f3aee4a8 ([PARSER]
    Handle backslash newlines properly after dollar sign) created
    cases where we make two consecutive calls to pungetc.  As we
    don't explicitly support that there are corner cases where you
    end up with garbage input leading to undefined behaviour.

    This patch adds explicit support for two consecutive calls to
    pungetc.

46a45ce02f ash: jobs: Don't attempt to access job table for job %0
Upstream commit:

    jobs: Don't attempt to access job table for job %0

    If job %0 is (mistakenly) specified, an out-of-bounds access to the
    jobtab occurs in function getjob() if num = 0:

            jp = jobtab + 0 - 1

    Fix this by checking that the job number is larger than 0 before
    accessing the jobtab.

8e2bc47d62 ash: [EVAL] Fix use-after-free in dotrap/evalstring
From upstream:

    [EVAL] Fix use-after-free in dotrap/evalstring

    The function dotrap calls evalstring using the stored trap string.
    If evalstring then unsets that exact trap string then we will end
    up using freed memory.

    This patch fixes it by making evalstring always duplicate the string
    before using it.

7ee7c6fc20 ash: Remove unused EV_BACKCMD flag
The original ash defered forking commands in backquotes so builtins
    could be run in the same context as the shell.  This behavior was
    controlled using the EV_BACKCMD to evaltree.

    Unfortunately, as Matthias Scheler noticed in 1999 (NetBSD PR/7814),
    the result was counterintuitive; for example, echo "`cd /`" would
    change the cwd.  So ash 0.3.5 left out that optimization.

eb17b6f6c9 ash: eval: Return status in eval functions
Backported from dash:

    eval: Return status in eval functions

    The exit status is currently clobbered too early for case statements
    and loops.  This patch fixes it by making the eval functions return
    the current exit status and setting them in one place -- evaltree.

    Harald van Dijk pointed out a number of bugs in the original patch.

source routing is not used in real world.

Tested that "traceroute -n ::1 100" and "traceroute -n 127.0.0.1 100"
both send 100 byte IP packets (this matches what traceroute on Fedora
Rawhide is doing).

61fcc8c781 vi: fix '' command (goto to prev context)
The '' command in vi doesn't currently work because after the first
apostrophe is read, the next character is converted to an integer
between 0 and 25 inclusive (for indexing the array of marks). The
comparison of the converted character with an apostrophe therefore never
succeeds, meaning that '' doesn't do anything.
