get_sched_policy uses the cpuset policy as fallback if the cpu cgroup
is not recognized. Pixel is currently not using the cpu cgroup for
background policy due to b/208895940.

Resolves a pair of TODO's, and makes a pair of error return
code paths not return null function pointers.
Note that:
system/netd/client/NetdClient.cpp
implements this as:
int checkSocket(int socketFd) {
if (socketFd < 0) {
return -EBADF;
}
int family;
socklen_t familyLen = sizeof(family);
if (getsockopt(socketFd, SOL_SOCKET, SO_DOMAIN, &family, &familyLen) == -1) {
return -errno;
}
if (!FwmarkClient::shouldSetFwmark(family)) {
return -EAFNOSUPPORT;
}
return 0;
}
$define CHECK_SOCKET_IS_MARKABLE(sock) \
do { \
int err = checkSocket(sock); \
if (err) return err; \
} while (false)
extern "C" int tagSocket(int socketFd, uint32_t tag, uid_t uid) {
CHECK_SOCKET_IS_MARKABLE(socketFd);
FwmarkCommand command = {FwmarkCommand::TAG_SOCKET, 0, uid, tag};
return FwmarkClient().send(&command, socketFd, nullptr);
}
extern "C" int untagSocket(int socketFd) {
CHECK_SOCKET_IS_MARKABLE(socketFd);
FwmarkCommand command = {FwmarkCommand::UNTAG_SOCKET, 0, 0, 0};
return FwmarkClient().send(&command, socketFd, nullptr);
}
which means it *already* verifies that the passed in sockfd
is >= 0 and a socket via getsockopt(SOL_SOCKET, SO_DOMAIN),
as such the 'fcntl(sockfd, F_GETFD)' check is spurious.

Also adjust permissions on /dev/hw_random to allow prng_seeder group
read access.
Manual testing protocol:
* Verify prng_seeder daemon is running and has the
correct label and uid/gid.
* Verify prng_seeder socket present and has correct
label and permissions
* Verify no SELinux denials
* strace a libcrypto process and verify it reads seeding
data from prng_seeder (e.g. strace bssl rand -hex 1024)
* strace seeder daemon to observe incoming connections
(e.g. strace -f -p `pgrep prng_seeder`)
* Kill daemon, observe that init restarts it
* strace again and observe clients now seed from new instance

It's useful to have a group that shares a numeric id with Linux and
macOS. "root" doesn't count because group 0 is actually called "wheel"
on the BSDs, and macOS has "daemon" and "kmem" as its groups 1 and 2.
This lets us have toybox tar tests that have the same results on all
supported OSes without special handling.

Every app will now have a corresponding supplemental process associated
with it. We need an utility method to map one to the other.
Implementation details: supplemental process uid will be between range
20k-30k. As such, it will be a 10k offset from app id. See ag/16621743.

Previously, each file/dir in a filesystem had to have exactly one
matching entry in the canned fs_config file. With this change, the
config file can have multiple entries for the same path. e.g.
/lib/libfoo.so 1000 1000 0644
/lib/libfoo.so 1000 2000 0644 capabilities=0x30
In this case, the last matching entry is chosen and used. This is to
make it possible to customize system-provided (and thus generic)
fs_config file with a user-provided (and thus context-specific) one.
