- 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).

-
- When the best port is changed, but the ID of the best clock doesn't
- change (e.g. a passive port is activated on link failure), reset the
- current delay and other master/link-specific state to avoid the switch
- throwing the clock off.

- clock: Reset clock check on best clock/port change.
-
- Reset the clock check when the best clock or port changes, together with
- the other state like current estimated delay and frequency. This avoids
- false positives if the clock is controlled by an external process when
- not synchronized by PTP (e.g. phc2sys -rr).

- port: Don't renew raw transport.
-
- Renewing of the transport on announce/sync timeout is needed in the
- client-only mode to avoid getting stuck with a broken multicast socket
- when the link goes down.
-
- This shouldn't be necessary with the raw transport. Closing and binding
- of raw sockets can apparently be so slow that it triggers a false
- positive in the clock check.

- 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).

- phc2sys: move read_phc into clock_adj.c
-
- The read_phc function implemented in phc2sys.c is used to perform clock
- comparison between two arbitrary clocks using clock_gettime.
-
- This support is used to allow phc2sys to work on any pair of clocks and
- is implemented in a very similar manner as the kernel PTP_SYS_OFFSET
- ioctls.
-
- Make this function easier to re-use by moving it out of phc2sys.c and
- into a more accessible location. clockadj.c seems like a reasonable
- location as this file has many functions which deal with clockid_t
- values, and this functionality is tangentially related to adjusting
- clocks.
-
- Moving this function will allow using it in the phc_ctl program in a
- future change.
-
- Notice that read_phc returned 0 on failure and 1 on success. This is
- fairly non-standard, so lets update clockadj_compare to return 0 on
- success and -1 on failure. Fix the call sites to check correctly and
- report an error.

-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.

-Author: Miroslav Lichvar <mlichvar@redhat.com>
-Date: Tue Mar 8 11:47:00 2022 +0100
-
- Add support for binding sockets to virtual clocks.
-
- With the latest kernels it is possible to create virtual PHCs on top of
- a free-running physical PHC. In order for the application to get
- timestamps captured by the clock which it is controlling, it needs to
- bind its sockets to the clock using a new field in the SO_TIMESTAMPING
- option.
-
- Extend the interface structure with the vclock index and modify the
- transport code to pass it to sk_timestamping_init() to bind the sockets
- to the clock.

-
- tlv: Add PORT_HWCLOCK_NP.
-
- Add a new command to get the PHC index associated with the port. This
- will be needed for phc2sys -a to use the correct PHC for synchronization
- if ptp4l is using a virtual clock.
-
- The TLV also contains a flag indicating a virtual clock.
-
- To follow the PORT_PROPERTIES_NP access policy, PORT_HWCLOCK_NP is
- limited to the UDS-RW port.
-
- (Rebased to 3.1.1)

- phc2sys: Use PHC index from PORT_HWCLOCK_NP.
-
- When running in the automatic mode, get the PHC index of the port
- from PORT_HWCLOCK_NP instead of calling sk_get_ts_info(). This allows
- phc2sys -a to synchronize (to) a virtual clock.

- timemaster: Add support for virtual clocks.
-
- Add "use_vclocks" option to enable synchronization with virtual clocks.
- This enables multiple ptp4l instances sharing an interface to use
- hardware timestamping. By default, vclocks are enabled if running on
- Linux 5.18 or later, which should have all features to make them work as
- well as physical clocks.
-
- When preparing the script, count how many vclocks are needed for each
- physical clock. Add a placeholder option in the form of "--phc_index
- %PHC0-0%" to the generated ptp4l commands that need hardware clock. The
- index of the virtual clock is unknown at this point.
-
- When running the script (not just printing), create the required number
- of virtual clocks by writing to /sys/.../n_vclocks and fix the
- --phc_index options to refer to the indices of the created vclocks. On
- exit, remove the virtual clocks to restore the original state.

- sk: Don't return error for zero-length messages.
-
- 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.").
