    This patch fixes the issue by sanitising all environment variable names
    upon entry into the shell.

    [EVAL] Avoid using undefined handler

    setjmp with the possible "goto *done", where savehandler is used.

60ca834358 ash: [MEMALLOC] Add pushstackmark
Upstream commit:

    Author: Herbert Xu <herbert@gondor.apana.org.au>
    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:

    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.

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.

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.

The "homegrown" glob code is retained (ifdef'ed out).

92d98f0612 ifupdown: when flushing addresses with "ip", add label %label%
User report:

or our board we setup eth0:0 on a 10.10.10.x/29 netwrok.

The problem is ip addr flush dev eth0:0 removes all ip addresses from
eth0.  You can see this if you run
ip -stat -stat addr flush dev eth0:0

2: eth0    inet 172.27.105.10/22 brd 172.27.107.255 scope global eth0
       valid_lft forever preferred_lft forever
2: eth0    inet 10.10.10.9/29 scope global eth0:0
       valid_lft forever preferred_lft forever
2: eth0    inet6 fe80::a2f6:fdff:fe18:2b13/64 scope link
       valid_lft forever preferred_lft forever

*** Round 1, deleting 3 addresses ***
*** Flush is complete after 1 round ***

4ff86df861 libnetlink: fix alignment of netlink messages
A padding to align a message should not only be added between
different attributes of a netlink message, but also at the end of the
message to pad it to the correct size.

Without this patch the following command does not work and returns an
error code:
ip link add type nlmon

Without this ip from busybox sends this:

sendmsg(3, {msg_name={sa_family=AF_NETLINK, nl_pid=0, nl_groups=00000000},
	msg_namelen=12, msg_iov=[{iov_base={{len=45, ...},
		"\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\20\0\22\0\t\0\1nlmon"}, iov_len=45}],
	msg_iovlen=1, msg_controllen=0, msg_flags=0}, 0) = 45
return value: 2

The normal ip utile from iproute2 sends this:

sendmsg(3, {msg_name={sa_family=AF_NETLINK, nl_pid=0, nl_groups=00000000},
	msg_namelen=12, msg_iov=[{iov_base={{len=48, ...},
		"\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\20\0\22\0\t\0\1nlmon\0\0\0"}, iov_len=48}],
	msg_iovlen=1, msg_controllen=0, msg_flags=0}, 0) = 48
return value: 0

With this patch ip from busybox sends this:

sendmsg(3, {msg_name={sa_family=AF_NETLINK, nl_pid=0, nl_groups=00000000},
	msg_namelen=12, msg_iov=[{iov_base={{len=48, ...},
		"\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\20\0\22\0\t\0\1nlmon\0\0\0"}, iov_len=48}],

When "set -e" option is on, shell must exit when any command fails,
including compound commands of the form (compound-list) executed in a
subshell. Bash and dash shells have this behaviour.

Also add a corresponding testcase.

d2c5de0130 svlogd: strip leading '!' from processor lines
When using svlogd's processor functionality to run arbitrary commands
on log rotation, the line in the config is executed verbatim, i.e. the
exclamation mark is included.

For example, if the config file contains:

    s100
    !cat

then when it's time to rotate the log files after each 100 bytes, sh -c
"!cat" will be run, instead of sh -c "cat" as intended. The result is
svlogd logging

    /bin/bash: !cat: command not found
    svlogd: warning: processor failed, restart: /tmp/svlogd/

over and over again as it keeps attempting to execute the processor and
failing (unless you happen to have a "!cat" binary around :)).

Skipping the exclamation mark when performing the wstrdup() fixes the
issue.
