Security Fixes:
- rndc "" could trigger an assertion failure in named. This flaw is
disclosed in (CVE-2017-3138). [RT #44924]
- Some chaining (i.e., type CNAME or DNAME) responses to upstream
queries could trigger assertion failures. This flaw is disclosed in
CVE-2017-3137. [RT #44734]
- dns64 with break-dnssec yes; can result in an assertion failure. This
flaw is disclosed in CVE-2017-3136. [RT #44653]
- If a server is configured with a response policy zone (RPZ) that
rewrites an answer with local data, and is also configured for DNS64
address mapping, a NULL pointer can be read triggering a server
crash. This flaw is disclosed in CVE-2017-3135. [RT #44434]
- A coding error in the nxdomain-redirect feature could lead to an
assertion failure if the redirection namespace was served from a
local authoritative data source such as a local zone or a DLZ instead
of via recursive lookup. This flaw is disclosed in CVE-2016-9778.
[RT #43837]
- named could mishandle authority sections with missing RRSIGs,
triggering an assertion failure. This flaw is disclosed in
CVE-2016-9444. [RT #43632]
- named mishandled some responses where covering RRSIG records were
returned without the requested data, resulting in an assertion
failure. This flaw is disclosed in CVE-2016-9147. [RT #43548]
- named incorrectly tried to cache TKEY records which could trigger an
assertion failure when there was a class mismatch. This flaw is
disclosed in CVE-2016-9131. [RT #43522]
- It was possible to trigger assertions when processing responses
containing answers of type DNAME. This flaw is disclosed in
CVE-2016-8864. [RT #43465]

Since a while, the semantic of BR2_PREFER_STATIC_LIB has been changed
from "prefer static libraries when possible" to "use only static
libraries". The former semantic didn't make much sense, since the user
had absolutely no control/idea of which package would use static
libraries, and which packages would not. Therefore, for quite some
time, we have been starting to enforce that BR2_PREFER_STATIC_LIB
should really build everything with static libraries.
As a consequence, this patch renames BR2_PREFER_STATIC_LIB to
BR2_STATIC_LIBS, and adjust the Config.in option accordingly.
This also helps preparing the addition of other options to select
shared, shared+static or just static.
Note that we have verified that this commit can be reproduced by
simply doing a global rename of BR2_PREFER_STATIC_LIB to
BR2_STATIC_LIBS plus adding BR2_PREFER_STATIC_LIB to Config.in.legacy.

Remove --localstatedir=/var from all autotools packages where it is no longer
needed.
Also remove --localstatedir=/var/lib/dhcp from package dhcp. localstatedir is
used by dhcp to set the default directory for the leases files. This can also
be done by setting --with-*-lease-file=/var/lib/dhcp/*, which is done in
dhcp.mk.
A custom --localstatedir is left in:
* proftpd.mk
* mysql.mk
This is safe to do:
One of the good thing with autoconf is that if you pass:
--localstatedir=/var ... --localstatedir=/var/something
Then /var/something will be used. So, we can set --localstatedir=/var
by default in the infrastructure, and still have certain packages doing
weird things override it. [Thanks to Thomas Petazzoni]

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.
