Backported commit f774703cb1eee058a346aec3341fee0be329bd6d
Author: Karthikkumar V <kvaloor@altiostar.com>
Date: Fri Feb 26 06:54:07 2021 +0000
Clock Class Threshold Feature addition for PTP4L
This code changes brings in the ability to program the acceptable
clockClass threshold beyond which device will move to holdover/free-run.
Default clockClass threshold is 248.
Example Use-Case:
This is needed in the cases where T-SC/T-BC Slave might want to listen
only on PRC clockCLass and anything beyond that might not be acceptible
and would want to go to holdover (with SyncE backup or internal oscillator).

From 4b05d4b5d70c1ba76d95f94f1f4821c4b715fefe Mon Sep 17 00:00:00 2001
From: Richard Cochran <richardcochran@gmail.com>
Date: Sat, 17 Apr 2021 15:15:18 -0700
Subject: [PATCH 2/2] Validate the messageLength field of incoming messages.
The PTP messageLength field is redundant because the length of a PTP
message is precisely determined by the message type and the appended
TLVs. The current implementation validates the sizes of both the main
message (according to the fixed header length and fixed length by
type) and the TLVs (by using the 'L' of the TLV).
However, when forwarding a message, the messageLength field is used.
If a message arrives with a messageLength field larger than the actual
message size, the code will read and possibly write data beyond the
allocated buffer.
Fix the issue by validating the field on ingress. This prevents
reading and sending data past the message buffer when forwarding a
management message or other messages when operating as a transparent
clock, and it also prevents a memory corruption in msg_post_recv()
after forwarding a management message.

commit 1a2dfe9b00b79a59acf905476bbc33c74d5770a3
Author: Jacob Keller <jacob.e.keller@intel.com>
Date: Thu Jul 8 12:59:30 2021 -0700
Increase the default tx_timestamp_timeout to 10
The tx_timestamp_timeout configuration defines the number of
milliseconds to wait for a Tx timestamp from the kernel stack. This
delay is necessary as Tx timestamps are captured after a packet is sent
and reported back via the socket error queue.
The current default is to poll for up to 1 millisecond. In practice, it
turns out that this is not always enough time for hardware and software
to capture the timestamp and report it back. Some hardware designs
require reading timestamps over registers or other slow mechanisms.
This extra delay results in the timestamp not being sent back to
userspace within the default 1 millisecond polling time. If that occurs
the following can be seen from ptp4l:
ptp4l[4756.840]: timed out while polling for tx timestamp
ptp4l[4756.840]: increasing tx_timestamp_timeout may correct this issue,
but it is likely caused by a driver bug
ptp4l[4756.840]: port 1 (p2p1): send sync failed
ptp4l[4756.840]: port 1 (p2p1): MASTER to FAULTY on FAULT_DETECTED
(FT_UNSPECIFIED)
This can confuse users because it implies this is a bug, when the
correct solution in many cases is to just increase the timeout to
a slightly higher value.
Since we know this is a problem for many drivers and hardware designs,
lets increase the default timeout.
Note that a longer timeout should not affect setups which return the
timestamp quickly. On modern kernels, the poll() call will return once
the timestamp is reported back to the socket error queue. (On old
kernels around the 3.x era the poll will sleep for the full duration
before reporting the timestamp, but this is now quite an old kernel
release).

Log optimization for ptp4l in jbod and client only mode (clientOnly=1 and boundary_clock_jbod=1)
The LISTENING port prints continuously
"selected best master clock 000000.0000.000003
updating UTC offset to 37"
We limited the log such that now it prints only when there is a
change in the best-master clock.

Log optimization for ptp4l in jbod and client only mode (clientOnly=1 and boundary_clock_jbod=1)
The port other than SLAVE (LISTENING port) prints an error
"port 1: master state recommended in slave only mode
ptp4l[1205469.356]: port 1: defaultDS.priority1 probably misconfigured"
for every ANNOUNCE RECEIPT Timeout.
This log is printed when the event EV_RS_MASTER is thrown
in clientOnly mode. But single port clientOnly mode will never
hit this event instead EV_RS_GRAND_MASTER will be hit.
EV_RS_MASTER is thrown when clientOnly=1 and boundary_clock_jbod=1
which results in continuous printing. So EV_RS_MASTER check when
clientOnly=1 to print this error can be avoided.

sysoff: Add support for PTP_SYS_OFFSET_PRECISE ioctl.
This ioctl uses cross timestamping for a more accurate measurement of
the offset. It is supported on some onboard Intel NICs using the e1000e

two clocks. Negate the offset and switch the timestamp before passing
them to the servo.
This makes the synchronization between PHC and system clock symmetric.

phc2sys: Fix frequency estimation when synchronizing a PHC to the system clock.
When synchronizing a PHC to the Linux system clock (CLOCK_REALTIME),
the phc2sys uses the sysoff method, reversing the master and slave
roles.
The offset between a master clock and a slave clock is given by
offset = slave_ts - master_ts,
and the call to sysoff_measure() provides the 'offset' and 'slave_ts'
values. The needed local time stamp on the 'master' is given by
master_ts = slave_ts - offset,
but the code calcuates
master_ts = slave_ts + offset.
When passed to the servo, the local time stamp is used to estimate the
frequency offset between the two clocks before starting the main
synchronization loop. The effect of the bug may be seen with a simple
test. Here is a sample output with the existing code.
$ sudo testptp -d /dev/ptp1 -f 62400000
frequency adjustment okay
$ sudo ./phc2sys -m -q -c eth6 -s CLOCK_REALTIME -O0

rtnl: add team activebackup support
This patch add team interface activebackup mode support. As linux team use
genl netlink message, when we get a rtnl link change notify, we have to setup
a new genl socket and request the current active port.
v2: check nlmsg_len before copy rta_data
v3: a) Do not make rtnl_buf global as it may be freed by calling rtnl_close()
while we are using it in rtnl_link_status()
b) Reorder declarations of variables as reversed Christmas tree for
function rtnl_link_status()
c) remove rtnl_len
v4: Remove the first !rtnl_buf check in rtnl_link_status as it's alway true
v5: a) Re-order {nl, rtnl}_open and add function nl_close()
b) revert the v3_{a,c}, v4 changes, use nl_close to close genl fd
c) do not use len in get_team_active_iface() as it may mislead reader
v6: Return index at the end to fix fd leak in get_team_active_iface()

port: should check the new phc_index before switching
In logic, when we want to switch phc, we should check if the new phc
index is valid instead of checking the previous one.
In reality, if we use linux team interface with activebackup mode. As
teamd is a userspace tool, it sets the new slave as active port after
receiving link change message. If we set current active port down and
another slave up. There is a race that we receive the new slave's link
up message while active port(ts_index) is still the old one. This means
we may use a link down interface as ts_index and get phc_index with -1.
If we update the p->phc_index to -1, there will be no possibility to
change it back to other value as we swith phc only when p->phc_index >= 0.
With this fix, we will not switch phc_index until receiving the real
active port(p->iface->ts_info.phc_index >= 0) update message.

clock: Rename UDS variables to read-write.
In preparation for a new read-only UDS port, rename variables of the
current UDS port to make it clear it is read-write, as opposed to
read-only.

commit 1f74a16502b55ce8eaed3d7488542e5469ac8263
Author: Miroslav Lichvar <mlichvar@redhat.com>
Date: Thu Feb 11 16:47:11 2021 +0100
clock: Add read-only UDS port for monitoring.
Add a second UDS port to allow untrusted applications to monitor ptp4l.
On this "read-only" UDS port disable non-GET actions and forwarding.
The path can be configured with the uds_ro_address option (default is
/var/run/ptp4lro).
Forwarding is disabled to limit the access to the local ptp4l instance.
Subscriptions are not enabled to prevent the applications from making a
large number of subscriptions or interfere with applications that have
access to the read-write UDS port.

commit 9633ab52460f58c92c6daa35e9d24e4ce9c5ab1c
Author: Miroslav Lichvar <mlichvar@redhat.com>

Avoid fault when receiving zero length packets
sk: Don't return error for zero-length messages.
The manpage for recvmsg says -1 will be returned on error, Zero indicates an
"orderly shutdown", presumably only in case of stream sockets.
Further, UNIX Network Programming, Vol 1 says ".. a return value of 0 from
recvfrom is acceptable for a datagram protocol"
The recvmsg() call can return zero for a zero-length UDP message, which
should be handled as a bad message and not a fault of the port. This was
addressed in commit 6b61ba29c78e ("Avoid fault when receiving zero
length packets"), but later regressed in commit a6e0b83bd503
("sk: Convey transmit path errors to the caller.").
Such packets have been observed in the wild, aimed at PTP's multicast
address and port, possibly related to malformed management queries.
Patch to properly check return from recvmesg and not trigger the fault
codepath. Instead, such packets are treated as "Bad Message" the same as
non-zero but still too-short UDP payloads.
