When updating and potentially removing event subscribers, the code uses
the simple list traversal macro. As a result, the list will become
corrupted whenever a subscriber is removed. This patch fixes the issue
by using the appropriate macro.
Fixes: 5104e3e56b59 ("Event subscribing")
Unfortunately the SNMP code still has issues like not passing the
valgrind test, and no one is able to finish this up right now. This
patch removes the SNMP program so that the upcoming release does not
contain unfinished work, potentially misleading end users about the
scope and completeness of
Currently there is a method to convert a timespec into a tmv_t, but
not the other way round. This patch adds the missing function in
anticipation of a new feature that will need this conversion.

The one user of the function, posix_clock_open(), simply open codes
the closing call to phc_close(). This patch provides a method to
balance closing and opening of a posix clock. In addition, the
phc_ctl program never explicitly closed the opened clock, and so this
patch adds the missing call.
Upcoming functionality will need to configure the input and output pins of
PHC devices. However, this requires fairly recent kernel support. This
patch adds the needed definitions for compiling with older kernel headers.
In addition, kernel v5.4 introduced a second set of ioctls for the
I have been preparing Balint Ferencz's ts2phc program for review on
this list. The present series presents a mixture of fixes and new
code in support of the upcoming GrandMaster features.
Patches 1-3 are random fixes found along the way.
Patches 4-6 add new helper code, preparing for GM support.
In anticipation of support for external time stamping in PHC devices, this
patch adds wrapper functions around the pin functionality.
