Changelog: https://gitlab.isc.org/isc-projects/bind9/-/blob/v9_18_8/CHANGES --- 9.18.7 released --- 5962. [security] Fix memory leak in EdDSA verify processing. (CVE-2022-38178) [GL #3487] 5960. [security] Fix serve-stale crash that could happen when stale-answer-client-timeout was set to 0 and there was a stale CNAME in the cache for an incoming query. (CVE-2022-3080) [GL #3517] 5959. [security] Fix memory leaks in the DH code when using OpenSSL 3.0.0 and later versions. The openssldh_compare(), openssldh_paramcompare(), and openssldh_todns() functions were affected. (CVE-2022-2906) [GL #3491] 5958. [security] When an HTTP connection was reused to get statistics from the stats channel, and zlib compression was in use, each successive response sent larger and larger blocks of memory, potentially reading past the end of the allocated buffer. (CVE-2022-2881) [GL #3493] 5957. [security] Prevent excessive resource use while processing large delegations. (CVE-2022-2795) [GL #3394] 5956. [func] Make RRL code treat all QNAMEs that are subject to wildcard processing within a given zone as the same name. [GL #3459] 5955. [port] The libxml2 library has deprecated the usage of xmlInitThreads() and xmlCleanupThreads() functions. Use xmlInitParser() and xmlCleanupParser() instead. [GL #3518] 5954. [func] Fallback to IDNA2003 processing in dig when IDNA2008 conversion fails. [GL #3485] 5953. [bug] Fix a crash on shutdown in delete_trace_entry(). Add mctx attach/detach pair to make sure that the memory context used by a memory pool is not destroyed before the memory pool itself. [GL #3515] 5952. [bug] Use quotes around address strings in YAML output. [GL #3511] 5951. [bug] In some cases, the dnstap query_message field was erroneously set when logging response messages. [GL #3501] 5948. [bug] Fix nsec3.c:dns_nsec3_activex() function, add a missing dns_db_detachnode() call. [GL #3500] 5947. [func] Change dnssec-policy to allow graceful transition from an NSEC only zone to NSEC3. [GL #3486] 5946. [bug] Fix statistics channel's handling of multiple HTTP requests in a single connection which have non-empty request bodies. [GL #3463] 5945. [bug] If parsing /etc/bind.key failed, delv could assert when trying to parse the built in trust anchors as the parser hadn't been reset. [GL !6468] 5944. [bug] Fix +http-plain-get and +http-plain-post options support in dig. Thanks to Marco Davids at SIDN for reporting the problem. [GL !6672] 5942. [bug] Fix tkey.c:buildquery() function's error handling by adding the missing cleanup code. [GL #3492] 5941. [func] Zones with dnssec-policy now require dynamic DNS or inline-siging to be configured explicitly. [GL #3381] 5938. [bug] An integer type overflow could cause an assertion failure when freeing memory. [GL #3483] 5936. [bug] Don't enable serve-stale for lookups that error because it is a duplicate query or a query that would be dropped. [GL #2982] 5935. [bug] Fix DiG lookup reference counting bug, which could be observed in NSSEARCH mode.

Poky
Poky is an integration of various components to form a pre-packaged build system and development environment which is used as a development and validation tool by the Yocto Project. It features support for building customised embedded style device images and custom containers. There are reference demo images ranging from X11/GTK+ to Weston, commandline and more. The system supports cross-architecture application development using QEMU emulation and a standalone toolchain and SDK suitable for IDE integration.
Additional information on the specifics of hardware that Poky supports is available in README.hardware. Further hardware support can easily be added in the form of BSP layers which extend the systems capabilities in a modular way. Many layers are available and can be found through the layer index.
As an integration layer Poky consists of several upstream projects such as BitBake, OpenEmbedded-Core, Yocto documentation, the 'meta-yocto' layer which has configuration and hardware support components. These components are all part of the Yocto Project and OpenEmbedded ecosystems.
The Yocto Project has extensive documentation about the system including a reference manual which can be found at https://docs.yoctoproject.org/
OpenEmbedded is the build architecture used by Poky and the Yocto project. For information about OpenEmbedded, see the OpenEmbedded website.
Contribution Guidelines
The project works using a mailing list patch submission process. Patches should be sent to the mailing list for the repository the components originate from (see below). Throughout the Yocto Project, the README files in the component in question should detail where to send patches, who the maintainers are and where bugs should be reported.
A guide to submitting patches to OpenEmbedded is available at:
https://www.openembedded.org/wiki/How_to_submit_a_patch_to_OpenEmbedded
There is good documentation on how to write/format patches at:
https://www.openembedded.org/wiki/Commit_Patch_Message_Guidelines
Where to Send Patches
As Poky is an integration repository (built using a tool called combo-layer), patches against the various components should be sent to their respective upstreams:
OpenEmbedded-Core (files in meta/, meta-selftest/, meta-skeleton/, scripts/):
- Git repository: https://git.openembedded.org/openembedded-core/
- Mailing list: openembedded-core@lists.openembedded.org
BitBake (files in bitbake/):
- Git repository: https://git.openembedded.org/bitbake/
- Mailing list: bitbake-devel@lists.openembedded.org
Documentation (files in documentation/):
- Git repository: https://git.yoctoproject.org/cgit/cgit.cgi/yocto-docs/
- Mailing list: docs@lists.yoctoproject.org
meta-yocto (files in meta-poky/, meta-yocto-bsp/):
- Git repository: https://git.yoctoproject.org/cgit/cgit.cgi/meta-yocto
- Mailing list: poky@lists.yoctoproject.org
If in doubt, check the openembedded-core git repository for the content you intend to modify as most files are from there unless clearly one of the above categories. Before sending, be sure the patches apply cleanly to the current git repository branch in question.
