For devices that use a programmable clock for the AVB reference clock,
the driver may need to enable them. Add code to find the optional clock
and enable it when available.

The AVB driver assumes there is an external crystal, but it could
be clocked by other means. In order to enable a programmable
clock, it needs to be added to the clocks list and enabled in the
driver. Since there currently only one clock, there is no
clock-names list either.
Update bindings to add the additional optional clock, and explicitly
name both of them.

enetc: support PTP Sync packet one-step timestamping
This patch-set is to add support for PTP Sync packet one-step timestamping.
Since ENETC single-step register has to be configured dynamically per
packet for correctionField offeset and UDP checksum update, current
one-step timestamping packet has to be sent only when the last one
completes transmitting on hardware. So, on the TX, this patch handles
one-step timestamping packet as below:
- Trasmit packet immediately if no other one in transfer, or queue to
skb queue if there is already one in transfer.
The test_and_set_bit_lock() is used here to lock and check state.
- Start a work when complete transfer on hardware, to release the bit
lock and to send one skb in skb queue if has.
Changes for v2:
- Rebased.
- Fixed issues from patchwork checks.
- netif_tx_lock for one-step timestamping packet sending.
Changes for v3:
- Used system workqueue.
- Set bit lock when transmitted one-step packet, and scheduled
work when completed. The worker cleared the bit lock, and
transmitted one skb in skb queue if has, instead of a loop.

And the configuration for one-step timestamping on ENETC before
transmitting is,
- Set one-step timestamping flag in extension BD.
- Write 30 bits current timestamp in tstamp field of extension BD.
- Update PTP Sync packet originTimestamp field with current timestamp.
- Configure single-step register for correctionField offeset and UDP
checksum update.

Mark TX timestamp type per skb on skb->cb[0], instead of
global variable for all skbs. This is a preparation for
one step timestamp support.
For one-step timestamping enablement, there will be both
one-step and two-step PTP messages to transfer. And a skb
queue is needed for one-step PTP messages making sure
start to send current message only after the last one
completed on hardware. (ENETC single-step register has to
be dynamically configured per message.) So, marking TX
timestamp type per skb is required.

====================
Ensuring net sysctl isolation
This patchset is the result of an audit of /proc/sys/net to prove that
it is safe to be mouted read-write in a container when a net namespace
is in use. See [1].
The first commit adds code to detect sysctls which are not netns-safe,
and can "leak" changes to other net namespaces.
My manual audit found, and the above feature confirmed, that there are
two nf_conntrack sysctls which are in fact not netns-safe.
I considered sending the latter to netfilter-devel, but I think it's
better to have both together on net-next: Adding only the former causes
undesirable warnings in the kernel log.
[1]: https://github.com/opencontainers/runc/issues/2826
====================
Signed-off-by: David S. Miller <davem@davemloft.net>
These sysctls point to global variables:
- NF_SYSCTL_CT_MAX (&nf_conntrack_max)
- NF_SYSCTL_CT_EXPECT_MAX (&nf_ct_expect_max)
- NF_SYSCTL_CT_BUCKETS (&nf_conntrack_htable_size_user)
Because their data pointers are not updated to point to per-netns
structures, they must be marked read-only in a non-init_net ns.
Otherwise, changes in any net namespace are reflected in (leaked into)
all other net namespaces. This problem has existed since the
introduction of net namespaces.
The current logic marks them read-only only if the net namespace is
owned by an unprivileged user (other than init_user_ns).
Commit d0febd81ae ("netfilter: conntrack: re-visit sysctls in
unprivileged namespaces") "exposes all sysctls even if the namespace is
unpriviliged." Since we need to mark them readonly in any case, we can
forego the unprivileged user check altogether.

This adds an ensure_safe_net_sysctl() check during register_net_sysctl()
to validate that sysctl table entries for a non-init_net netns are
sufficiently isolated. To be netns-safe, an entry must adhere to at
least (and usually exactly) one of these rules:
1. It is marked read-only inside the netns.
2. Its data pointer does not point to kernel/module global data.
An entry which fails both of these checks is indicative of a bug,
whereby a child netns can affect global net sysctl values.
If such an entry is found, this code will issue a warning to the kernel
log, and force the entry to be read-only to prevent a leak.
To test, simply create a new netns:
$ sudo ip netns add dummy
As it sits now, this patch will WARN for two sysctls which will be
addressed in a subsequent patch:
- /proc/sys/net/netfilter/nf_conntrack_max
- /proc/sys/net/netfilter/nf_conntrack_expect_max
