[Linuxptp-devel] [PATCH RFC 0/3] Fix UTC offset issue

This patch series addresses the jumping UTC offset issue that occurs when the default TAI-UTC offset is out of date, but a then GM master appears providing the correct offset, only to disappear again. Review and comments are most welcome. Thanks, Richard Richard Cochran (3): Simplify UTC

[Linuxptp-devel] [PATCH RFC 2/3] Latch the UTC offset.

When acting as a slave, we accept the foreign master's advertised TAI-UTC offset for as long as that master is present. However, when the master disappears, we fall back to the initial offset value. As a result of this behavior, when starting with an out of date initial offset, losing a foreign

[Linuxptp-devel] [PATCH RFC 3/3] Remove redundant test on the UTC flags.

Now that we test the UTC flags in clock_update_slave(), the similar code in clock_utc_correct() is redundant. Signed-off-by: Richard Cochran --- clock.c | 8 +--- 1 file changed, 1 insertion(+), 7 deletions(-) diff --git a/clock.c b/clock.c index da1fcc4..9d224c9

[Linuxptp-devel] [PATCH] ptp4l: Add IPoIB interface support for ptp4l

The current implementation of ptp4l always assumes 6 octets MAC address, which is correct for Ethernet interfaces but not for IPoIB interfaces (that have 20 octets MAC), therefore running ptp4l over IPoIB interface does not function correctly. In Infiniband, every interface has three identifiers:
