main/pmos-base-ui: use dnsane for DNS

Fixes #1430 by basically filtering DNS queries to remove any with addresses
that might cause traffic to go over a lower priority interface. See that issue
for a more detailed explanation of the problem.

It does this by:
        1) configuring NetworkManager to send DNS config to resolvconf, instead
           of writing to resolv.conf directly. In my (limited) testing, this
           seems to be necessary to get NM to trigger resolvconf which is
           needed for...
        2) configuring resolvconf to ignore any DNS it receives and use
           localhost, when writing resolv.conf

openresolv is used because the alternative of modifying resolv.conf
manually gets messy, specifically with apk where it may not replace
/etc/resolv.conf if the user / something else has modified it...

Note that there's still some possibilities for apps that have hardcoded DNS
nameservers to bypass dnsane. It's not trivial to catch this. The most straight
forward way is to use a firewall rule to redirect all outbound DNS to dnsane.
But this would break mmsd and any other apps that actually need to query
specific nameservers to function properly.

I used a SIM that had a mobile data connection, but traffic was dropped by the
carrier outside of the phone. In other words, my phone was often in the exact
situation described in #1430. When connected to wifi, I could very easily
notice when traffic was being routed incorrectly because anything destined for
mobile data would fail (pages stopped loading, etc). After some amount of
casual testing while using the phone "normally", I haven't noticed any failures
yet from that problem.

+Subject: [PATCH] Revert "PR25882, .gnu.attributes are not checked for shared
+ libraries"
+
+This revert is needed to avoid wrongly tagging objects with the incompatible
+IBM long double ABI, which is not supported by musl and will result in
+linking errors if used.
+
+This reverts commit a8acd6eeb6dc2cc5460ece90f90ebe36b56b20ba.

+MIME-Version: 1.0

-This patch allows using gcc-go with libucontext. For this purpose,
-it unconditionally links gcc-go against -lucontext. Furthermore,
-it undefines SETCONTEXT_CLOBBERS_TLS in proc.c to prevent usage
-of makecontext/swapcontext feature that are not support by libucontext.
+Patch from Sören Tempel.

+Subject: [PATCH] syscall, runtime: always call XSI strerror_r
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
 
-glibc provides two version of strerror_r() depending on a feature test
-macro. The first is the XSI-compliant version which returns an int, the
-second is GNU-specific and returns a char pointer.
+This does the right thing for either glibc or musl on GNU/Linux.
 
-Similarity, gcc's libgo provides two implementations of Errstr() both of
-which use strerror_r(). On Linux, it is assumed that the GNU-specific
-strerror_r version is used. However, musl only provides the
-XSI-compliant version of strerror_r. This patch enables the generic
-Errstr() implementation which also uses the XSI-compliant version of
-strerror_r.
+Based on patch by Sören Tempel.

+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
 
-On glibc-based systems, off_t is a 32-bit type on 32-bit systems and a
-64-bit type on 64-bit systems by default. However, on systems using musl
-libc off_t is unconditionally a 64-bit type. As such, it is insufficient
-to use a uintptr type for the mmap offset parameter.
+The last argument to the C mmap function is type off_t, not uintptr.
+On some 32-bit systems, off_t is larger than uintptr.
 
-Presently, the (incorrect) mmap declaration causes a libgo run-time
-failure on 32-bit musl systems (fatal error: runtime: cannot allocate
-memory). This commit fixes this run-time error.
+Based on patch by Sören Tempel.

+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
 
-This patch allows using gcc-go with libucontext. For this purpose,
-it unconditionally links gcc-go against -lucontext. Furthermore,
-it undefines SETCONTEXT_CLOBBERS_TLS in proc.c to prevent usage
-of makecontext/swapcontext feature that are not support by libucontext.

-Subject: [PATCH] Use generic errstr.go implementation on musl

+Subject: [PATCH] syscall, runtime: always call XSI strerror_r
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
 
-glibc provides two version of strerror_r() depending on a feature test
-macro. The first is the XSI-compliant version which returns an int, the
-second is GNU-specific and returns a char pointer.
+This does the right thing for either glibc or musl on GNU/Linux.
 
-Similarity, gcc's libgo provides two implementations of Errstr() both of
-which use strerror_r(). On Linux, it is assumed that the GNU-specific
-strerror_r version is used. However, musl only provides the
-XSI-compliant version of strerror_r. This patch enables the generic
-Errstr() implementation which also uses the XSI-compliant version of
-strerror_r.
+Based on patch by Sören Tempel.

+Subject: [PATCH] runtime: use _libgo_off_t_type when calling C mmap
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
 
-On glibc-based systems, off_t is a 32-bit type on 32-bit systems and a
-64-bit type on 64-bit systems by default. However, on systems using musl
-libc off_t is unconditionally a 64-bit type. As such, it is insufficient
-to use a uintptr type for the mmap offset parameter.
+The last argument to the C mmap function is type off_t, not uintptr.
+On some 32-bit systems, off_t is larger than uintptr.
 
-Presently, the (incorrect) mmap declaration causes a libgo run-time
-failure on 32-bit musl systems (fatal error: runtime: cannot allocate
-memory). This commit fixes this run-time error.
+Based on patch by Sören Tempel.

+Subject: [PATCH] syscall, runtime: always call XSI strerror_r
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
 
-glibc provides two version of strerror_r() depending on a feature test
-macro. The first is the XSI-compliant version which returns an int, the
-second is GNU-specific and returns a char pointer.
+This does the right thing for either glibc or musl on GNU/Linux.
 
-Similarity, gcc's libgo provides two implementations of Errstr() both of
-which use strerror_r(). On Linux, it is assumed that the GNU-specific
-strerror_r version is used. However, musl only provides the
-XSI-compliant version of strerror_r. This patch enables the generic
-Errstr() implementation which also uses the XSI-compliant version of
-strerror_r.
+Based on patch by Sören Tempel.

+Subject: [PATCH] runtime: use _libgo_off_t_type when calling C mmap
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
 
-On glibc-based systems, off_t is a 32-bit type on 32-bit systems and a
-64-bit type on 64-bit systems by default. However, on systems using musl
-libc off_t is unconditionally a 64-bit type. As such, it is insufficient
-to use a uintptr type for the mmap offset parameter.
+The last argument to the C mmap function is type off_t, not uintptr.
+On some 32-bit systems, off_t is larger than uintptr.
 
-Presently, the (incorrect) mmap declaration causes a libgo run-time
-failure on 32-bit musl systems (fatal error: runtime: cannot allocate
-memory). This commit fixes this run-time error.
+Based on patch by Sören Tempel.

+Subject: [PATCH] gcc: poison-system-directories
+
+Add /sw/include and /opt/include based on the original
+zecke-no-host-includes.patch patch.  The original patch checked for
+/usr/include, /sw/include and /opt/include and then triggered a failure and
+aborted.
+
+Instead, we add the two missing items to the current scan.  If the user
+wants this to be a failure, they can add "-Werror=poison-system-directories".

+Subject: [PATCH] Ensure that msgfmt doesn't encounter problems during gcc
+ bootstrapping.
+
+Solves error messages like the following:
+
+msgfmt: /var/tmp/portage/sys-devel/gcc-4.1.2/work/build/./gcc/libgcc_s.so.1: version `GCC_4.2.0' not found (required by /usr/lib/gcc/x86_64-pc-linux-gnu/4.5.3/libstdc++.so.6)
+
+The libgcc_s.so used during build doesn't satisfy the needs of the
+libstdc++.so that msgfmt is linked against. On the other hand, msgfmt
+is used as a stand-alone application here, and what library it uses
+behind the scenes is of no concern to the gcc build process.
+Therefore, simply invoking it "as usual", i.e. without any special
+library path, will make it work as expected here.

+Subject: [PATCH] riscv: disable multilib support
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+From the musl wiki [1]:
+
+	musl does not support sharing an include directory between archs
+	[…], and thus is not compatible with GCC-style multilib. It is
+	recommended that distributions build GCC with multilib disabled,
+	and use library directories named lib, not lib64 or lib32.
+
+For this reason, we patch existing GCC configuration files (gcc/config)
+to pin MULTILIB_OSDIRNAMES to lib, there is also a corresponding GCC
+upstream bug about this issue [2]. Avoiding the use of lib64 and lib32
+directories is a bit more difficult on the RISC-V architecture. This is
+due to the fact that the default RISC-V configuration does not only use
+the lib64 and lib32 directories but also subdirectories within these
+directories for different RISC-V ABIs (e.g. lp64d, lp64, …) [3].
+
+This patch aligns the RISC-V configuration with other architectures by
+pinning MULTILIB_OSDIRNAMES to lib for rv64gc (our default RISC-V
+-march). Furthermore, this patch removes the ABI-specific startfile
+prefix spec. Since both of these impact the default LIBRARY_PATH [4]
+this patch thereby aligns the default RISC-V LIBRARY_PATH with that from
+other Alpine architectures and thereby fixes #13369 [5].
+
+Incidentally, this also fixes gccgo on riscv64, as without this patch
+gccgo is otherwise not able to find the *.gox files for the Go standard
+library.
