Subject: [PATCH 11/47] phc2sys: extract PMC functionality into a smaller
struct pmc_node
This creates a smaller structure within phc2sys_private, which embeds
all properties related to the PMC. This structure is called "pmc_node",
which is somewhat reminiscent of the old name of phc2sys_private (struct
node). But the advantage is that struct pmc_node can be reused by other
modules.
The phc2sys code that is executed upon a subscription update,
recv_subscribed, is now refactored into a function pointer callback. It
is imaginable that other programs might to do other things in it.
Note that putting this function pointer in struct pmc_node is, long
term, maybe not the best of choices. It is only needed from the
run_pmc_events() code path, and could be therefore passed as a more
local callback to that function only. However, for that, further
refactoring is needed inside the common run_pmc() function, so that is
being left for another time.

Subject: [PATCH 12/47] phc2sys: make PMC functions non-static
In preparation of a trivial movement of code to pmc_common.c, remove the
"static" keyword from the functions that will end up there, since they
will be still called from phc2sys.c for now.

Subject: [PATCH 13/47] phc2sys: break out pmc code into pmc_common.c
The code through which phc2sys sends various PTP management messages to
ptp4l via pmc can be reused.
This patch is a trivial movement of that code to a separate translation
module, outside of phc2sys. This makes it available to other programs
that want to subscribe to port state change events too, such as ts2phc.

From c00e75286b2ad882cf8e89549ea58e438c877f95 Mon Sep 17 00:00:00 2001
From: Andre Mauricio Zelak <andre.zelak@windriver.com>
Date: Mon, 12 Jun 2023 14:40:59 -0300
Subject: [PATCH 14/47] Introduce the PMC agent module.
The logic for placing PTP management queries migrated out of phc2sys into
pmc_common in order to be shared with other programs in the future. This
logic uses pmc_common rather than extending it, and so it should live in
its own module stacked on top of pmc_common.
This patch moves the code into its own file verbatim without making any
other changes.

From f6d7bb0a62f15fcca0343c42891f7e056f502949 Mon Sep 17 00:00:00 2001
From: Andre Mauricio Zelak <andre.zelak@windriver.com>
Date: Mon, 12 Jun 2023 14:55:29 -0300
Subject: [PATCH 16/47] pmc_agent: Hide the implementation.
The PMC agent's implementation should not be exposed to its users. This
patch hides the details and provides a method to create an instance. In
addition, the signature of the receive callback is made generic, removing
the container_of pattern meant for sub-classing modules.
Signed-off-by: Richard Cochran <richardcochran@gmail.com>

Subject: [PATCH 19/47] Introduce error codes for the run_pmc method.
The run_pmc function is used by several of the PMC agent methods, but it
breaks the pattern of returning zero on success. However, the user facing
PMC agent methods will need to conform to the return code convention used
throughout the stack.
In order to migrate to proper return codes, this patch replaces the hard
coded result values with macros so that the interface methods can translate
them to the required semantics of zero on success.

Subject: [PATCH 21/47] pmc_agent: Simplify the update method.
The main method that causes the PMC agent to update its status takes a flag
that results in different behavior when push notifications are active.
This patch simplifies the interface by letting the agent remember whether
or not the caller subscribed to the notifications in the first place.

If the pmc pointer is not set, then there is no need to read the time only

Subject: [PATCH 23/47] pmc_agent: Remove bogus comparison between last update
and now.
The monotonic clock can never go backwards. If you take T1 and later T2
from that clock, then (T2 > T1) is always true.
This patch removes the useless test.
[ This test evolved over the years. Originally the time stamp in question
came from a PHC. ]

Subject: [PATCH 26/47] phc2sys: Fix null pointer de-reference in manual mode.
If both the -w and -O command line options are specified (or when
using -w when both source and destination clocks are PHCs), then
pointer to the PMC agent will be incorrectly freed.
Fix the segfault by introducing a method to "disable" the agent as was
done before the PMC agent code was introduced.
Unfortunately the resulting PMC agent API now has both create/destroy
and init/disable methods. This clunky arrangement can be cleaned up
later on, but it entails re-factoring the phc2sys program even more.

From 3e6dd047083625ca03df9b4bbdc781e7dd079ff2 Mon Sep 17 00:00:00 2001

Subject: [PATCH 29/47] pmc_agent: Generalize the method that queries the local
clock identity.
When started in automatic mode, the phc2sys program first queries the
local clock identification and then the number of ports immediately
afterwords. However, both of those values come from the default data
set. Make code both simpler and more efficient by caching the entire
data set inside of the agent.
A subsequent patch will fix the run_pmc_get_number_ports() method to
return the cached result.
The active word in the function's name is "query" rather that "get" in
order to distinguish methods that send and receive over the network
from those that merely return a cached value.

Subject: [PATCH 32/47] phc2sys: Fix regression in the automatic mode.
Commit ac7d69bbc476 ("pmc_agent: Convert the method that queries the
port properties.") had the well meant intention of the cleaning up the
error code semantics of the port properties query function. However,
that commit mixed up the normal, external semantics of zero meaning
success with the internal semantics where zero is an error. Correct
the issue by replacing the hard coded number with the proper macro.

Subject: [PATCH 34/47] 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.

Subject: [PATCH 35/47] 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.

From 2a6ddfe1b9700ce8e0c62da8a7a4f2edcd4e1cad Mon Sep 17 00:00:00 2001
From: Andre Mauricio Zelak <andre.zelak@windriver.com>
Date: Sun, 18 Jun 2023 20:58:34 -0300
Subject: [PATCH 37/47] Enhance phc2sys to accept multiple ptp4l inputs
A new configuration option called ha_enabled was created. When it is set 1
multiple ptp4l inputs are accepted and the high availability algorithms
are enabled.
In addition to ha_enabled 1 a set of interfaces must also be provided.
Each interface is one-to-one mapped to a clock source, and must be
associated to an unique ptp4l instance using the ha_uds_address
configuration option.
For example:
ha_enabled 1
[ens1f1]
ha_uds_address /var/run/ptp4l-ptp-inst1
[ens1f2]
ha_uds_address /var/run/ptp4l-ptp-inst2
A maximum of 128 interfaces is supported.
Regression: verify non HA phc2sys configuration
PASS: Verify auto configuration is still accepted.
PASS: Verify manual configuration with a single clock is still accepted.
PASS: Verify mix of manual and auto configuration is denied.
PASS: Verify manual configuration with zero clock sources is denied.
Test Plan: verify HA configuration
PASS: Verify HA is disabled by default.
PASS: Verify HA configuration with 1 or more clock source is accepted.
PASS: Verify ha_uds_address default value.

From 142b30b1f996a5bd48f0edc9b5fb0f51af0b97fd Mon Sep 17 00:00:00 2001

Subject: [PATCH 38/47] Best source selection algorithm
An algorithm to select the best available clock and use it
as clock source.
A new set of configuration options was introduced to control
the clock requirements. The clock which fails to match the
requirements is discarded.
If a single clock matches the requirements, it is selected
as source.
If one or more clock match requirements, the clock with the highest
priority is selected. In case of tie, the 1st configured clock is
selected.
And if no clock match requirements, the clock with the best local
clock class is selected.
The ha_priority option is an interface setting used to configure
the clock priority. The lowest priority is 0 and the highest is 254,
and the default value is 0.
The ha_min_local_clockClass option is a global setting for the minimal
local clock class requirement. It ranges from 6 to 255 and its default
is 135.
The ha_min_clockAccuracy option is a global setting for the minimal
clock accuracy requirement. It ranges from 0x00 to 0xff and its default
is 0xfe.
The ha_min_offsetScaledLogVariance is a global setting for the minimal
offset scaled log variance. It ranges from 0 to 65535 and its default
is 65535.
The ha_timeTraceable is a global setting to enable or disable
the time traceable verification. When it's set the clock
which time is not traceable is discarded.
The ha_frequencyTraceable is a global setting to enable or disable
the frequency traceable verification. When it's set the clock
which frequency is not traceable is discarded.
The ha_min_gm_ClockClass is a global setting for the minimal
GM clock class requirement. It ranges from 6 to 255 and its
default is 135.
Test Plan: clock selection algorithm
PASS: Verify clock is discarded when local clock class doesn't match
requirements.
PASS: Verify clock is discarded when local clock accuracy doesn't match
requirements.
PASS: Verify clock is discarded when local offset scaled log variance doesn't
match requirements.
PASS: Verify clock is discarded when time traceable verification is set 1 and
the clock hasn't time traceable flag set.
PASS: Verify clock is discarded when frequency traceable verification is set 1
and the clock hasn't frequency traceable flag set.
PASS: Verify clock is discarded when GM clock class doesn't match requirements.
PASS: Verify clock is accepted when time traceable verification is set 0 even
when clock hasn't time traceable flag set.
PASS: Verify clock is accepted when frequency traceable verification is set 0
even when clock hasn't frequency traceable flag set.
PASS: Verify the highest priority clock is selected when one or more clock
match the requirements.
PASS: Verify the 1st configured clock is selected when one or more clock of the
same priority match the requirements.
PASS: Verify the clock with highest local clock class is selected when no clock
match the requirements.

Subject: [PATCH 40/47] Forced lock a clock source in configuration
To help on maintenance and debuging tasks was implemented a configuration
to forced lock to a single clock. It disables the automatic clock
selection algorithm and lock to a source interface.
When an interface is configured with maximum ha_priority (254)
the source selection is locked to it, regardless of its clock
status.
When more than one source clock is configured with ha_priority 254
selects the 1st interface in the configuration file.
Test plan: forced lock by configuration
PASS: Verify the clock source is forced lock to an interface, regardless
its state.
PASS: Verify the clock source remains locked event after change the clock
state.
PASS: Verify the 1st configured interface with priority 254 is selected
when multiple interfaces has the same priority.

From fce993dd36e481aace337a62ff81331cd2411bec Mon Sep 17 00:00:00 2001

Subject: [PATCH 41/47] HA phc2sys com socket
A new communication path was created to retrieve status and to control
the high availability algorithm.
The ha_phc2sys_com_socket option is a global setting to configure
the socket path. Its default value is /var/run/phc2sys.
The command 'status' was created to retrieve the current HA clock status.
The answer is a table of configured clocks and its status.
act interface priority clockClass clockAcc offset time freq gm.
* ens2f1 200 248 0xfe 0xffff no no 6
ens1f2 100 248 0xfe 0xffff no no 6
Source forced? no
The * sign marks the active source clock.
The - sign marks the active candidate source clock, which will be set active
after the stability timer expiration.
The x sign marks the disabled interfaces (see 'disable source' command).
The 'Source forced?' field shows if the active source is forced lock or not.
The 'clock source' command can be used to retrive the active
clock source. It returns the interface name of the active
clock source or "None" when there is no one select.
The 'forced lock' command can be used to retrieve if the active
clock source is forced lock, and the clock source selection
algorithm is disabled. It returns "True" when is forced lock
and "False" otherwise.
Test plan: socket path configuration
PASS Verify the socket using the default path.
PASS Verify the socket using a given socket path.
Test plan: status command
PASS: Verify the 'status' command after start up.
PASS: Verify the 'status' command while stability timer is running.
PASS: Verify the 'status' command with a forced lock interface by
configuring ha_priority 254.
Test plan: clock source command
PASS: Verify the 'clock source' command response is the highest priority
interface after start up.
PASS: Verify the 'clock source' command response is the active interface
after the primary has degraded.
PASS: Verify the 'clock source' command response is the forced lock
interface, when ha_priority 254 is configured in one of them.
Test plan: forced lock command
PASS: Verify the 'forced lock' command response is 'False' when no
interface is configured with ha_priority 254.
PASS: Verify the 'forced lock' command response is 'True' when one
interface is configured with ha_priority 254.

interface of the clock source must be specified in the
command. For example:
'enable lock <interface-name>'
It returns "Success" or an error message. The error message
"Error: Usage 'enable lock <interface>'" is returned when
no interface was provided in the command. The error message
"Error: Interface not found!" is returned when the interface
provided is not found in the phc2sys configuration.
The command 'disable lock' is used to unlock the clock source
and re-enable the HA clock selection algorithm. It returns
"Success" even when the clock source was not locked.
Test plan: enable lock and disable lock commands
PASS: Verify the enable lock changes the clock source to the given
interface.
PASS: Verify that regardless the interface state, the clock source
remains locked.
PASS: Verify that disable lock command makes the better available
clock to be selected again.

From 27b5c6afff470053b30ade14537be43f1c1c376d Mon Sep 17 00:00:00 2001
From: Andre Mauricio Zelak <andre.zelak@windriver.com>
Date: Fri, 4 Aug 2023 19:01:57 -0300
Subject: [PATCH 43/47] Commands 'enable source' and 'disable source'.
These commands controls the list of clocks available to clock
selection algorithm.
At startup all sources are enabled and can be selected as clock
source. The 'disable source' command removes a given interface
from the available list and it can't be selected any more. The
'enable source' command re-enables the interface.
The last interface can't be disable. The disable command fails and
returns an error indicating the given interface is the last one.
If the active clock source interface is disabled than a new one
will be selected.
Every time the enable command is executed the clock selection
algorithm is executed and the best available clock is selected.
The enable and disable source commands won't affect the active
clock if one interface is forced lock as active.
The disabled interface is market with 'x' sign in the status
command.
Test plan: enable source and disable source commands
PASS: Verify a new interface is selected when the active one
is disabled.
PASS: Verify the primary interface is re-selected active after
it is enabled back.
PASS: Verify the disable source command fails when attempt to
disable the last enabled interface.
PASS: Verify the active interface don't change while one of them
are forced lock as active.
PASS: Verify the active interface dont't change after enabling
an interface while in forced lock mode.

From f480fb54182da36baeb35bac90154abafcaf854a Mon Sep 17 00:00:00 2001

Subject: [PATCH 46/47] Robustness improvements to phc2sys socket
When phc2sys abnormally exits the socket file might remain created.
To avoid error when phc2sys is relaunched, the exixting file is
deleted before recriating the socket.
If the peer application closes the socket before sending the
response completely, it will cause a broken pipe error. The
send function generates a SIGPIPE on broken pipe errors,
killing the phc2sys process unless MSG_NOSIGNAL flag is set.
Test plan: socket file
PASS: Verify that phc2sys can restart normally after killing it.
Test plan: SIGPIPE
PASS: Verify the phc2sys application don't exit when client socket
is closed before the respose is sent.

Subject: [PATCH 47/47] phc2sys without -w option.
Fix bad clock and pmc initialization when -w command argument
is not provided.
The pmc agent must be created and mapped to a clock source even
in cases the -w (wait for ptp4l) option is not used.
Test plan:
PASS: Verify phc2sys initializes without -w argument.
PASS: Verify phc2sys initializes with two ptp4l interfaces
configured.
