GCC and Clang are able to check the format arguments given to a
function and warn the user if there is a error in the format arguments
or if there is a potential uncontrolled format string security problem
in the code. GCC does this automatically for some functions like
printf(), but it is also possible to annotate other functions in a way
that it will check them too. This feature is used by glibc for many
functions. This patch adds the attribute to the some functions of musl
expect for these functions where gcc automatically adds it.
GCC automatically adds checks for these functions: printf, fprintf,
sprintf, scanf, fscanf, sscanf, strftime, vprintf, vfprintf and
vsprintf.
The documentation from gcc is here:
https://gcc.gnu.org/onlinedocs/gcc/Common-Function-Attributes.html
The documentation from Clang is here:
http://clang.llvm.org/docs/AttributeReference.html#format-gnu-format

vdso support is available on mips starting with kernel 4.4, see kernel
commit a7f4df4e21 "MIPS: VDSO: Add implementations of gettimeofday()
and clock_gettime()" for details.
These are my micro benchmark results for 1.000.000 calls to
clock_gettime(CLOCK_MONOTONIC, &tp)
without vdso:
root@OpenWrt:/# time ./vdso-test
real 0m 0.95s
user 0m 0.24s
sys 0m 0.70s
with vdso:
root@OpenWrt:/# time /usr/bin/vdso-test
real 0m 0.35s
user 0m 0.34s
sys 0m 0.00s

This reverts commit r48335
The workaround is incomplete and cannot cover all possible cases. The
only real solution to this problem is to disable this feature on
ARM11MPcore entirely.

This reverts commit r48276.
This can overwrite the caldata_backup partition, so the layout needs to
be changed in a different way.
Thanks to Arjen de Korte for spotting the issue.

This adds IPv6 support to qos-scripts for both tc/qdisc and the
iptables classification rules. The tc/qdisc part is accomplished
by removing "protocol ip" from the tc command line, causing the
rule to be applied to all protocols. The iptables part is
accomplished by adding each rule using both iptables and ip6tables.
This patch is based on previous work by Ilkka Ollakka and
Dominique Martinet.

This adds a "srciface" option that can be used on classification
rules in /etc/config/qos. This is useful to allow prioritization
based on the local network from which the traffic originates, for
example to deprioritize traffic from a guest network.
