This is a clean move. The content of netd.c is not changed. The object
name is still netd.o. But the module name is renamed to netd.o_mainline
to avoid name collision in sc-mainline-prod branch.
Modified Android.bp according to the file location. The sub_dir is
newly specified. The object file will be compiled to:
- apex/com.android.tethering/etc/bpf/net_shared/netd.o
The extracted programs and maps will be in:
- sys/fs/bpf/net_shared/
The netd.o will not be loaded in pre-T because the bpfloader before T
does not load objects from paths other than:
- apex/com.android.tethering/etc/bpf/
- /system/etc/bpf/

- Add a default to framework-connectivity-tiramisu for disabling
T-only build rules.
- Separate the tiramisu hidden apis from hiddenapi txt files, so
that the framework-connectivity-tiramisu file can avoid being
referenced by the APEX when the JAR is not part of it.

This change only apply to the device after T.
Use new bluetooth API to change bluetooth tethering settings and the
new API provide the callback to to notify Tethering when bluetooth
interface is ready. Tethering doesn't use bluetooth interface status
change event from netlink to add/remove IpServer anymore.

`service-connectivity` is a jar that system_server loads dynamically.
Such jars can be dexopted now. This CL adds `service-connectivity` to a
`systemserverclasspath_fragment`, which does not actually add the jar to
the classpath, but tells the build system to dexopt it.
NOTE: The corresponding `exported_systemserverclasspath_fragments` needs
to be added to the `prebuilt_apex` once a new prebuilt is dropped.

see kernel/private/wembley/+/refs/heads/tm-4.19/include/uapi/linux/if_arp.h
which has #define ARPHRD_PUREIP 520 (and is a Mediatek based device)
or Qualcomm based Pixel 3 and older kernels (<=4.9) which #define ARPHRD_RAWIP 530
(unlike Pixel 4/5 which are 4.14/4.19 and use the upstream ARPHRD_RAWIP of 519)
We stop supporting 520/530 starting with 5.11+ since those as GKI 2.0 only kernels
cannot be using non-upstream-ed constants (btw. this is probably true for 5.10-S
as well, but let's play it safe). For pre-5.11 we're lucky because even now
(with 5.15 released) upstream has yet to define an ARPHRD_* for either one of
520 or 530, so there's no harm in 'squatting' on this unused space.
This approach also means there's absolutely no change in behaviour on
pre-launch-T devices, since they all are at most running 5.10 kernels.
We'll be able to get rid of this code in the far future once we stop shipping
mainline tethering updates to pre-5.10 Mediatek or pre-4.14 Qualcomm devices.
This will likely be many years.

The defaults can be used to enable/disable connectivity next targets
depending on the branch, while minimizing merge conflicts.
The "next" target may use unstable APIs. It need to be disabled in the
branch which only have the last stable SDK available.
Also correct TetheringTestsLatestSdkLib which should use stable API.

The folder is currently used by tether offload only. Because we will
move netd.c and clatd.c to it, the folder should be moved to the upper
tier.
Also, rename bpf_tethering_headers to bpf_connectivity_headers so that
other connectivity code besides to tethering are justified to use it.

Note: due to the release version of the Connectivity/Tethering mainline
module being built from sc-mainline-prod, this won't actually take effect
until system/bpf bpfloader at version 0.6+ is merged in to that tree.
This doesn't really matter, since currently things default to v0.0+.
But there is no mainline module updatable pre-v0.2 supported OS
anyway. BpfLoader v0.2 is what shipped in Android S Beta 4 through
Android S Final.
Before S there simply was no bpfloader support for mainline updatable
ebpf code, while S Beta 3 and earlier shipped v0.0 which is badly
incompatible with even the current version of the mainline module.
Additionally v0.0 doesn't even parse this field, while v0.1 which
does was very short lived [~3 days] and can thus be utterly ignored.
As such this change is effectively a no-op, and even post merge
of bpfloader v0.6+ into sc-mainline-prod will still be effectively
a no-op.
So why do it? I want to explicitly document that these programs are S+,
so that I can change the default in the future to be T+.

With the network selection rewrite in S, rematching a single request can
now easily be done; this can be used as an optimization in
handleRegisterNetworkRequests to avoid rematching all requests when
registering a new one.
This can be disabled by a flag that is unset by default,

Define interfaces that match the signature of the existing
EthernetManager.TetheredInterfaceRequest and TetheredInterfaceCallback
classes and make EthernetManager.TetheredInterfaceRequest and
TetheredInterfaceCallback implement/subinterface these interfaces. The
new bluetooth API could also implement these interfaces to make API surface
consistent.
Test: TH would test the existing tests that use the subclass.

To avoid much code diverge between aosp and its downstream, we need to
separate the build target which build with latest stable sdk in release
branch and build with unfreeze sdk in dev branch. So we could use new
API with APIshim in dev branch without impacting release branch.
BYPASS_INCLUSIVE_LANGUAGE_REASON=the wording is the file name of
