- Author: Karthikkumar V <kvaloor@altiostar.com>

-     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).

-

- 

-     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.

-

-     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.

- 

-     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.

-     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.

-     

-     (Rebased to 3.1.1)

-     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.

This updates linuxptp to a more recent snapshots, drops included patches, and adds a few more that FB is in the process of upstreaming. Also temporarily disable three tests (16-largewander 19-externalstep 31-leapsecond) while we figure out why they're failing.

@leoleovich tested the el8 build and confirmed it looks sane

Looks reasonable to me, modulo lack of documentation of patches.

I would respectfully request that someone someday decides to document them or at least make it a standard practice going forward for new patches. :)
