net: ptp: introduce common defines for PTP message types

2020-11-23T21:43:07Z

Using PTP wide defines will obsolete different driver internal defines and uses of magic numbers. Signed-off-by: Christian Eggers Cc: Kurt Kanzenbach Reviewed-by: Vladimir Oltean Reviewed-by: Richard Cochran Signed-off-by: Jakub Kicinski

ptp: add stub function for ptp_get_msgtype()

2020-09-27T20:29:49Z

Added the missing stub function for ptp_get_msgtype(). Fixes: 036c508ba95e ("ptp: Add generic ptp message type function") Reported-by: Randy Dunlap Signed-off-by: Yangbo Lu Acked-by: Randy Dunlap # build-tested Signed-off-by: David S. Miller

ptp: Add generic ptp message type function

2020-08-19T23:07:49Z

The message type is located at different offsets within the ptp header depending on the ptp version (v1 or v2). Therefore, drivers which also deal with ptp v1 have some code for it. Extract this into a helper function for drivers to be used. Signed-off-by: Kurt Kanzenbach Reviewed-by: Richard Cochran Reviewed-by: Florian Fainelli Signed-off-by: David S. Miller

ptp: Add generic ptp v2 header parsing function

2020-08-19T23:07:49Z

Reason: A lot of the ptp drivers - which implement hardware time stamping - need specific fields such as the sequence id from the ptp v2 header. Currently all drivers implement that themselves. Introduce a generic function to retrieve a pointer to the start of the ptp v2 header.

ptp: Change ptp_class to a proper bitmask

2015-11-03T16:08:22Z

Change the definition of PTP_CLASS_L2 to not have any bits overlapping with the other defined protocol values, allowing the PTP_CLASS_* definitions to be for simple filtering on packet type. Signed-off-by: Stefan Sørensen Signed-off-by: David S. Miller

net: ptp: move PTP classifier in its own file

2014-04-01T20:43:18Z

This commit fixes a build error reported by Fengguang, that is triggered when CONFIG_NETWORK_PHY_TIMESTAMPING is not set: ERROR: "ptp_classify_raw" [drivers/net/ethernet/oki-semi/pch_gbe/pch_gbe.ko] undefined! The fix is to introduce its own file for the PTP BPF classifier, so that PTP_1588_CLOCK and/or NETWORK_PHY_TIMESTAMPING can select it independently from each other. IXP4xx driver on ARM needs to select it as well since it does not seem to select PTP_1588_CLOCK or similar that would pull it in automatically. This also allows for hiding all of the internals of the BPF PTP program inside that file, and only exporting relevant API bits to drivers. This patch also adds a kdoc documentation of ptp_classify_raw() API to make it clear that it can return PTP_CLASS_* defines. Also, the BPF program has been translated into bpf_asm code, so that it can be more easily read and altered (extensively documented in [1]). In the kernel tree under tools/net/ we have bpf_asm and bpf_dbg tools, so the commented program can simply be translated via `./bpf_asm -c prog` where prog is a file that contains the commented code. This makes it easily readable/verifiable and when there's a need to change something, jump offsets etc do not need to be replaced manually which can be very error prone. Instead, a newly translated version via bpf_asm can simply replace the old code. I have checked opcode diffs before/after and it's the very same filter.
