The one in this file requires libbinder and cannot be used when
libbinder is not present (e.g., when compiling against the NDK).
This allows users of this code not to link against libbinder, and
have the resulting binary not depend on it:
$ m CtsNativeNetPlatformTestCases netd_integration_test
$ objdump -p out/target/product/vsoc_x86_64/testcases/netd_integration_test/x86_64/netd_integration_test64 | grep NEEDED | grep libbinder

While at it enforce a min/max of 4 kiB and 256 MiB.
A bpf ringbuffer must be an integer multiple of page size
(which is at least 4kiB), so 4kB is forced.
256 MiB upper limit is probably higher than it should be,
but it's really only here to avoid the u32/s32 conversion
mess that happens for 2+ GiB.

called when Os.read is blocked and waiting for the input.
Ignore such events.

Change this constant to public so that the implementation of other
type of DNS record, such as SVCB record, can reuse this constant
instead of defining a duplicate one.

Also maintain the case with ThrowingRunnable by overloading.

destroyLiveTcpSockets APIs are replacement of socketDestroy in
NetdNativeService which has logging for target uids and duration.
Logging them would be useful in debug.
So adding equivalent logging to destroyLiveTcpSockets APIs.

This `as? T` instruction warns that this is an unchecked cast.
It's unchecked in the literal sense : the compiler actually
doesn't check that the var is of that type. Accordingly, this
will only fail if `it` is null, which never happens.
Concretely what that means is that Java code calling this
method like
expect(AVAILABLE, network)
...will actually pass for *any* callback matching the network,
because the class is not checked.
Thankfully this code is recent and there doesn't seem to be a
lot of tests that got accepted by this bug when they should
have been rejected.

new test in this patch that fails before but succeeds after
Change-Id: I2e48dae28ff92045f002cfb2798d383c9c19d5ed
x86 has 2 obvious ABIs:
32-bit registers/pointers/system calls (i386/i486/i586/i686)
64-bit registers/pointers/system calls (amd64 / x86_64)
but there also exists a third:
the memory optimizing hybrid 'x32' which uses 64-bit registers,
with 32-bit pointers, and 64-bit system calls (with minor tweaks).
(there is also technically an aarch64/arm64-ilp32 ABI mirroring x32)
Note: It would probably be trivial to add support if we wanted to.

Consumer pos is only written to by userspace (except for
initialization), so reading from it does not require a memory barrier.
This change also moves producer pos to be acquired before anything else
and marks start_ptr as volatile, so it is only read once.

This change adds support for 32 bit kernels by capping mProducerPos to
4 bytes. mConsumerPos (which is written to by userspace) continues to
use 8 bytes. (This can be done because an entire page is allocated for
mConsumerPos to control access permissions). In a 32 bit kernel, that
means that the top order bits are just ignored. In addition, comparisons
in userspace only use the bottom 4 bytes to be bitness agnostic.
Test: atest BpfRingbufTest
Change-Id: I7fe6d9000a151512785f1aa2a53fa97d31967d19
Both consumer and producer position are wrapped in an std::atomic and
extended to uint64_t to enforce atomic access.
See resulting assembly instructions for aosp_cf_x86_phone-userdebug:
frameworks/libs/net/common/native/bpf_headers/include/bpf/BpfRingbuf.h:212
2d: 8b 41 18 mov 0x18(%ecx),%eax
external/libcxx/include/atomic:926 (discriminator 4)
30: f3 0f 7e 00 movq (%eax),%xmm0
This will not work on a 32 bit kernel (so we might want to explicitly
check for that in the test).
