Backporting following fixes:
a72457b61df0 libubus: increase stack depth for processing obj msgs
ef038488edc3 libubus: process pending messages in data handler if stack depth is 0
2099bb3ad997 libubus: use list_empty/list_first_entry in ubus_process_pending_msg
where at least commit 2099bb3ad997 ("libubus: use
list_empty/list_first_entry in ubus_process_pending_msg") fixes UAF
issue I've introduced in commit c5f2053dfcfd ("workaround possibly false
positive uses of memory after it is freed") while fixing another false
positive UAF reported[1] by clang's static analyzer.
Those fixes are being used in master/21.02 for about 6 months, so should
be tested enough and considered for backporting. I've runtested those
fixes on mvebu/turris-omnia and ipq40xx/glinet-b1300 devices.

-----------------------------------------------------
This is the buildsystem for the OpenWrt Linux distribution.
To build your own firmware you need a Linux, BSD or MacOSX system (case
sensitive filesystem required). Cygwin is unsupported because of the lack
of a case sensitive file system.
You need gcc, binutils, bzip2, flex, python, perl, make, find, grep, diff,
unzip, gawk, getopt, subversion, libz-dev and libc headers installed.
1. Run "./scripts/feeds update -a" to obtain all the latest package definitions
defined in feeds.conf / feeds.conf.default
2. Run "./scripts/feeds install -a" to install symlinks for all obtained
packages into package/feeds/
3. Run "make menuconfig" to select your preferred configuration for the
toolchain, target system & firmware packages.
4. Run "make" to build your firmware. This will download all sources, build
the cross-compile toolchain and then cross-compile the Linux kernel & all
chosen applications for your target system.
Sunshine!
