This patch series brings together the base functionality
and new netlink APIs for flexible path management from userspace.
Further it extends the MPTCP self-testing framework to support the new
netlink APIs along with the ability to capture MPTCP netlink events
to aid in functional/behavioral validations. Lastly, it adds a
self-testing script with a suite of test cases covering the entire
range of the new userspace path management capabilities.
Note: This series depends on the prior patchset "mptcp: fixes and
enhancements related to path management".
v5:
-Primary change over v4 is the reliance on userspace
managed listener sockets for receiving MPJ requests.
-Addressed CI reported issues.
v6:
-Put all distinct userspace PM related code into a separate compilation
unit: pm_userspace.c.
-Made a few internal helpers non-static (now declared in protocol.h) to
facilitate the above change.
-Use the pm spinlock instead of mptcp_data_lock() to synchronize
access to the per-msk local_addr_list.
