Kernel for Galaxy S24, rebased on CLO sources (WIP)
Enabling CONFIG_NETFILTER_FAMILY_BRIDGE causes the new element, hooks_bridge[] to be added to netns_nf. Since the KMI is frozen this could not be added. The only instantiation of struct netns_nf is as an embedded field of struct net. So instead of adding the field to struct netns_nf, a new "struct ext_net" is added that contains struct net and the new hooks_bridge[] field. An accessor function, get_nf_hooks_bridge() is added to get a pointer to the new field. There is a global init_net of type struct net which must be special cased since it is not a member of a struct ext_net. All other instances of struct net are allocated via net_alloc() which now allocates a struct ext_net. Since CONFIG_NETFILTER_FAMILY_BRIDGE is a hidden config that is needed for vendor modules, it is enabled via init/Kconfig.gki.

How do I submit patches to Android Common Kernels
-
BEST: Make all of your changes to upstream Linux. If appropriate, backport to the stable releases. These patches will be merged automatically in the corresponding common kernels. If the patch is already in upstream Linux, post a backport of the patch that conforms to the patch requirements below.
- Do not send patches upstream that contain only symbol exports. To be considered for upstream Linux,
additions of
EXPORT_SYMBOL_GPL()
require an in-tree modular driver that uses the symbol -- so include the new driver or changes to an existing driver in the same patchset as the export. - When sending patches upstream, the commit message must contain a clear case for why the patch is needed and beneficial to the community. Enabling out-of-tree drivers or functionality is not not a persuasive case.
- Do not send patches upstream that contain only symbol exports. To be considered for upstream Linux,
additions of
-
LESS GOOD: Develop your patches out-of-tree (from an upstream Linux point-of-view). Unless these are fixing an Android-specific bug, these are very unlikely to be accepted unless they have been coordinated with kernel-team@android.com. If you want to proceed, post a patch that conforms to the patch requirements below.
Common Kernel patch requirements
- All patches must conform to the Linux kernel coding standards and pass
scripts/checkpatch.pl
- Patches shall not break gki_defconfig or allmodconfig builds for arm, arm64, x86, x86_64 architectures (see https://source.android.com/setup/build/building-kernels)
- If the patch is not merged from an upstream branch, the subject must be tagged with the type of patch:
UPSTREAM:
,BACKPORT:
,FROMGIT:
,FROMLIST:
, orANDROID:
. - All patches must have a
Change-Id:
tag (see https://gerrit-review.googlesource.com/Documentation/user-changeid.html) - If an Android bug has been assigned, there must be a
Bug:
tag. - All patches must have a
Signed-off-by:
tag by the author and the submitter
Additional requirements are listed below based on patch type
Requirements for backports from mainline Linux: UPSTREAM:
, BACKPORT:
- If the patch is a cherry-pick from Linux mainline with no changes at all
- tag the patch subject with
UPSTREAM:
. - add upstream commit information with a
(cherry picked from commit ...)
line - Example:
- if the upstream commit message is
- tag the patch subject with
important patch from upstream
This is the detailed description of the important patch

- then Joe Smith would upload the patch for the common kernel as

- If the patch requires any changes from the upstream version, tag the patch with
BACKPORT:
instead ofUPSTREAM:
.- use the same tags as
UPSTREAM:
- add comments about the changes under the

been merged into Linux mainline
- tag the patch subject with

. This must be a stable maintainer branch (not rebased, so don't uselinux-next
for example). - if changes were required, use
