CVE-2017-8779: rpcbind through 0.2.4, LIBTIRPC through 1.0.1 and 1.0.2-rc
through 1.0.2-rc3, and NTIRPC through 1.4.3 do not consider the maximum RPC
data size during memory allocation for XDR strings, which allows remote
attackers to cause a denial of service (memory consumption with no
subsequent free) via a crafted UDP packet to port 111, aka rpcbomb.
For more details, see:

Backport upstream fix to version 0.2.3 and unconditionally include syslog.h
to fix a build issue when RPCBIND_DEBUG is disabled (which it is in
Buildroot).

The check-package script when ran gives warnings on ordering issues
on all of these Config files. This patch cleans up all warnings
related to the ordering in the Config files for packages starting with
the letter r in the package directory.
The appropriate ordering is: type, default, depends on, select, help
See http://nightly.buildroot.org/#_config_files for more information.

rpcbind uses the __P() macro defined in sys/cdefs.h but does not
includes it explicitly, relying on the glibc behaviour to include it
from its own headers.
But this macro does nothing but expands as its argument. In the past,
it did provide support for pre-ANSI compilers that did not support
function prototypes. Those are now gone, and glibc provides this macro
for legacy code.
Patch out the use of __P() altogether.

rpcbind depends on libtirpc, which used to depend on
host-pkgconf. However, since commit
aee57627b0, the dependency of libtirpc
on host-pkgconf has been removed, because libtirpc no longer uses
PKG_CHECK_MODULES().
However, rpcbind does use PKG_CHECK_MODULES(). It used to work because
host-pkgconf was brought into the build by the dependency on libtirpc,
but that's no longer the case. Bottom line: we need to make rpcbind
depend on host-pkgconf, which is exactly what this commit does.

Since SourceForge sometimes serves us faulty tarballs, we can tons of
autobuild failures:
http://autobuild.buildroot.org/results/9fb/9fba5bf086a4e7a29e5f7156ec43847db7aacfc4/http://autobuild.buildroot.org/results/6c8/6c837b244c45ac3b3a887734a371cd6d226cf216/
...
Fix that by adding hash files for all SourceForge-hosted packages (thos
etht did not already have it).
We normally prefer to use hashes published by upstream, but hunting them
all one by one is a tedious task, so those hashes were all locally
computed with a script that searched for SF-hosted packages, downloades
the associated tarball, computed the hash, and stored it in the
corresponding .hash file.
Also, SF publishes sha1 hashes, while I used the stronger sha256, since
sha1 is now considered to be relatively weak.

As discussed, users should use a rootfs overlay or a post-build script
instead of a custom skeleton to override files installed by Buildroot,
so there is no point in having conditions when installing init scripts

The Buildroot coding style defines one space around make assignments and
does not align the assignment symbols.
This patch does a bulk fix of offending packages. The package
infrastructures (or more in general assignments to calculated variable
names, like $(2)_FOO) are not touched.
Alignment of line continuation characters (\) is kept as-is.
The sed command used to do this replacement is:
find * -name "*.mk" | xargs sed -i \
-e 's#^\([A-Z0-9a-z_]\+\)\s*\([?:+]\?=\)\s*$#\1 \2#'
-e 's#^\([A-Z0-9a-z_]\+\)\s*\([?:+]\?=\)\s*\([^\\]\+\)$#\1 \2 \3#'
-e 's#^\([A-Z0-9a-z_]\+\)\s*\([?:+]\?=\)\s*\([^\\ \t]\+\s*\\\)\s*$#\1 \2 \3#'
-e 's#^\([A-Z0-9a-z_]\+\)\s*\([?:+]\?=\)\(\s*\\\)#\1 \2\3#'
Brief explanation of this command:
^\([A-Z0-9a-z_]\+\) a regular variable at the beginning of the line
\([?:+]\?=\) any assignment character =, :=, ?=, +=
\([^\\]\+\) any string not containing a line continuation
\([^\\ \t]\+\s*\\\) string, optional whitespace, followed by a
line continuation character
\(\s*\\\) optional whitespace, followed by a line
continuation character
Hence, the first subexpression handles empty assignments, the second
handles regular assignments, the third handles regular assignments with
line continuation, and the fourth empty assignments with line
continuation.
This expression was tested on following test text: (initial tab not
included)
FOO = spaces before
FOO = spaces before and after
FOO = tab before
FOO = tab and spaces before
FOO = tab after
FOO = tab and spaces after
FOO = spaces and tab after
FOO = \
FOO = bar \
FOO = bar space \
FOO = \
GENIMAGE_DEPENDENCIES = host-pkgconf libconfuse
FOO += spaces before
FOO ?= spaces before and after
FOO :=
FOO =
FOO =
FOO =
FOO =
$(MAKE1) CROSS_COMPILE=$(TARGET_CROSS) -C
AT91BOOTSTRAP3_DEFCONFIG = \
AXEL_DISABLE_I18N=--i18n=0
After this bulk change, following manual fixups were done:
- fix line continuation alignment in cegui06 and spice (the sed
expression leaves the number of whitespace between the value and line
continuation character intact, but the whitespace before that could have
changed, causing misalignment.
- qt5base was reverted, as this package uses extensive alignment which
actually makes the code more readable.
Finally, the end result was manually reviewed.

When a package A depends on config option B and toolchain option C, then
the comment that is given when C is not fulfilled should also depend on B.
For example:
config BR2_PACKAGE_A
depends on BR2_B
depends on BR2_LARGEFILE
depends on BR2_WCHAR
comment "A needs a toolchain w/ largefile, wchar"
depends on !BR2_LARGEFILE || !BR2_WCHAR
This comment should actually be:
comment "A needs a toolchain w/ largefile, wchar"
depends on BR2_B
depends on !BR2_LARGEFILE || !BR2_WCHAR
or if possible (typically when B is a package config option declared in that
same Config.in file):
if BR2_B
comment "A needs a toolchain w/ largefile, wchar"
depends on !BR2_LARGEFILE || !BR2_WCHAR
[other config options depending on B]
endif
Otherwise, the comment would be visible even though the other dependencies
are not met.
This patch adds such missing dependencies, and changes existing such
dependencies from
depends on BR2_BASE_DEP && !BR2_TOOLCHAIN_USES_GLIBC
to
depends on BR2_BASE_DEP
depends on !BR2_TOOLCHAIN_USES_GLIBC
so that (positive) base dependencies are separate from the (negative)
toolchain dependencies. This strategy makes it easier to write such comments
(because one can simply copy the base dependency from the actual package
config option), but also avoids complex and long boolean expressions.

libtirpc fails to build with the Blackfin external toolchains provided
by Analog Devices, because their uClibc configuration doesn't include
AI_ADDRCONFIG. In order to prevent such build failures to happen, we
simply prevent libtirpc from being selected when such toolchains are
used. This is not a big problem, since they provide native RPC
support.
Also, since they provide native RPC, we don't have to propagate this
new dependency to the reverse dependencies of libtirpc, because they
all use native RPC when available. The exception to this rule is the
rpcbind package, which can only use the libtirpc implementation of
RPCs, and not the native one of C libraries. Therefore, the dependency
is propagated to the rpcbind package.
