There are 3 timers described in rfc8899#section-5.1.1: PROBE_TIMER, PMTU_RAISE_TIMER, CONFIRMATION_TIMER This patches adds a 'probe_timer' in transport, and it works as either PROBE_TIMER or PMTU_RAISE_TIMER. At most time, it works as PROBE_TIMER and expires every a 'probe_interval' time to send the HB probe packet. When transport pl enters COMPLETE state, it works as PMTU_RAISE_TIMER and expires in 'probe_interval * 30' time to go back to SEARCH state and do searching again. SCTP HB is an acknowledged packet, CONFIRMATION_TIMER is not needed. The timer will start when transport pl enters BASE state and stop when it enters DISABLED state.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
