      toolchain: Rework external toolchain libc selection · c8e68150
      Florian Fainelli authored 
      
Make it a choice menu which offers the 3 C libraries we know about: glibc,
uClibc and musl. While at it, make it possible for the external toolchain libc
to select USE_GLIBC, USE_UCLIBC or USE_MUSL which is used by several packages
to conditionally include specific CFLAGS (e.g: iproute2).

Because USE_GLIBC et al. can now be selected by external toolchains, we need to
restrict the per-libc menus to check on !EXTERNAL_TOOLCHAIN.

While at it, make musl the default C library for external toolchain to match
the internal toolchain.

      toolchain/uClibc: enable UCLIBC_HAS_OBSOLETE_BSD_SIGNAL · 336ad4c9
      Hauke Mehrtens authored 
      This is required to build net-snmp.

If that options is disabled in uClibc then net-snmp doesn't
detect sighold support on its configuration stage and so
defines HAVE_SIGHOLD as 0. That in its turn causes compilation of
the following branch of timerPause() in apps/snmpnetstat:
------------------>8----------------
    int             oldmask;
    oldmask = sigblock(sigmask(SIGALRM));
    if (!signalled) {
        sigpause(0);
    }
    sigsetmask(oldmask);
------------------>8----------------

Now in uClibc all 3 sigblock(), sigmask() and sigsetmask()
were removed back in 2005, see:
https://git.busybox.net/uClibc/commit/?id=5aa7aa7fa7ec2a0fe567ac0b2595b46add6f3594



And all that causes net-snmp linkage to fail this way:
------------------>8----------------
.libs/if.o: In function `intpr':
if.c:(.text+0x908): undefined reference to `sigmask'
if.c:(.text+0x90e): undefined reference to `sigblock'
if.c:(.text+0x924): undefined reference to `sigsetmask'
------------------>8----------------

If we enable UCLIBC_HAS_OBSOLETE_BSD_SIGNAL in uClibc then
branch with sighold is used in timerPause() and everything builds as
expected.

      toolchain: add support of ARCv2 architecture · 7b821a5a
      John Crispin authored 
      
This change adds support of ARC ISAv2 processors in
OpenWRT toolchain.

In general gcc for ARC may compile code for both ISA versions
simultaneously but libgcc will be built only for default
architecture that's why it's necessary to specify --with-cpu
on gcc configuration.

As for uClibc we need to use different configurations for
different ARC ISAs.

      toolchain: add support of ARC architecture · 8b5d644b
      Felix Fietkau authored 
      This includes binutils, gcc, gdb and uClibc-ng.

Latest release of ARC gcc (as of today it is "arc-2015.06")
is based on upstream gcc 4.8.4.

Sources are available on GitHub, see:
https://github.com/foss-for-synopsys-dwc-arc-processors/gcc

Latest release of ARC binutils (as of today it is "arc-2015.06")
is based on upstream binutils 2.23.

Sources are available on GitHub, see:
https://github.com/foss-for-synopsys-dwc-arc-processors/binutils-gdb/releases/tag/arc-2015.06

Latest release of ARC GDB (as of today this is "arc-2015.06-gdb")
is based on upstream gdb 7.9.1.

Sources are available on GitHub, see:
https://github.com/foss-for-synopsys-dwc-arc-processors/binutils-gdb/releases/tag/arc-2015.06-gdb



Note that for binutils and gdb that come from unified git repository
(which is the case for upstream binutils/gdb today) we need to disable
building of gdb in binutils and binutils in gdb hence in binutils:
------>8------
--disable-sim
--disable-gdb
------>8------

and in gdb:
------>8------
--disable-binutils
--disable-ld
--disable-gas
------>8------

Also in gdb we disable sim because if the following breakage while
building with it:
------------>8------------
/usr/bin/env bash ./../common/genmloop.sh -shell /usr/bin/env bash \
        -mono -fast -pbb -switch sem5-switch.c \
        -cpu a5f -infile ./mloop5.in \

      uclibc-ng: bump version from 1.0.6 to 1.0.8 · 02df774b
      Felix Fietkau authored 
      
2 new architectures were added in between 1.0.6 and 1.0.8 in uClibc-ng,
these are:
 * lm32
 * or1k

Even thought both are not yet supported in OpenWRT it's important to
disable them both in default config file otherwise user prompt will
appear during uClibc configuration asking to select desired
architecture.

      toolchain/uClibc: add support of uClibc-ng · 57a70e8a
      Felix Fietkau authored 
      uClibc-ng is a spin-off of original uClibc, see http://www.uclibc-ng.org/



We try to regularly add changes from uClibc to uClibc-ng.
We even sent patches and bug reports to the uClibc mailing list.
The config file is compatible between uClibc-ng 1.0 and uClibc git master.
This might change in the future.

Our main goal is to provide regularly a stable and tested release
to make embedded system developers happy.

The main advantage of uClibc-ng over olde good uClibc is regular releases
so there's no need to keep tons of patches on top of years old
0.9.33.2

Build-tested for
 [1] ARM: Sunxi generic
 [2] MIPS: Netgear WNDR3600/3700/3800

Run-tested for [yet out of the tree] Synopsys Designware ARC AXS101.

      uClibc: add signal info for seccomp related SIGSYS · 6ab2bcfe
      John Crispin authored 
      
uClibc doesn't define signal info for the SIGSYS signal which is issued
in case of hitting a syscall prohibited by seccomp.
This is sad as it makes debugging seccomp filter policies impossible on
some architectures (at least ARM and PowerPC, maybe also others) which
do not coincidentally set si_value.sival_int as the syscall number.

To fix this, import the definitions and macros needed from glibc.

      Support for building an hardened OpenWRT · 491f3fc0
      John Crispin authored 
      
Introduce configuration options to build an "hardened" OpenWRT.

Options to enable Stack-Smashing Protection, FORTIFY_SOURCE and RELRO
have been introduced.

uClibc makefile now automatically detects if SSP support is necessary.

hostapd makefile has been fixed to use "^" as sed separator since
using a comma was problematic when using "-Wl,-z,now" and the like in
TARGET_CFLAGS.

Currently enabling SSP on user space depends on enabling SSP kernel
side, this is due to the fact that TARGET_CFLAGS are used to build
kernel modules (at least). Suggestions on how to avoid this are welcome.
Using "select" instead of "depends on" doesn't seem to work with choice
entries.

Tested with a lantiq (WBMR) router, GCC 4.8, uClibc and a subset of
the available packages.
Needs to be tested with GCC 4.9 and the remaining packages.
PIE not currently included.

This seems to also depend on the host system used, e.g. running a fresh
checkout on a Debian 7.6 system triggered this error, while running the
very same stuff on an Ubuntu 12.10 Quantal Quetzal does not trigger it.

This is the configuration I used:

-snip-
buildbot@buildbot:~/openwrt-nls.git$ scripts/diffconfig.sh
CONFIG_TARGET_ar71xx=y
CONFIG_TARGET_ar71xx_generic=y
CONFIG_TARGET_ar71xx_generic_Default=y
CONFIG_DEVEL=y
CONFIG_BUILD_NLS=y
CONFIG_DOWNLOAD_FOLDER="/srv/downloads/downloads"
-snap-

In the ticket mentioned above, a patch is referenced which solves this issue.

Note, that this issue is also present on 14.07.
