      lib:fix possible returning EINVAL when evl_attach* called by SCHED_RR threads · f20f616f
      lio authored 
      

When evl_attach_thread() was called,  a local stack variable *attrs* will copy-
from-user to linux-evl. The problem is that *attrs* initializes only two of its
members:attrs.sched_policy and attrs.sched_priority, but none of the other
members are initialized.

These uninitialized may be "zero" or any other random values, for example:
attrs->sched_rr_quantum may be some none-zero value when the threads under
discussion is a SCHED_RR task.
In this case, *attrs* copyed to linux-evl in *thread_common_ioctl()*, and
attrs->sched_rr_quantum is none-zero value; then fllowed call *set_time_slice*
will lead to a -EINVAL return for meet *quantum <= evl_get_clock_gravity()*.

This patch will initialize all members of *attrs* to zero.

      benchmarks/latmus: latmon: fix retrieval of histogram data · 1377720f
      Philippe Gerum authored 
      This is a general fix addressing several issues in the retrieval of
histogram data from latmon, which reverts #6b2425d8

 in the same move:

- use a safe socket send loop in order to cope with partial writes on
  the latmon side.

- drop the very notion of warmup time, the system must be ready to
  respond with no delay or preparation, and the average figures won't
  be affected over long enough runs anyway.

      lib: convert to HM diagnostic messages · 3fef97c6
      Philippe Gerum authored 
      

Since ABI 23, the core is able to channel T_WOSS, T_WOLI and T_WOSX
error notifications through the offender's observable component if
present.

Convert all SIGDEBUG_xxx cause codes to the new EVL_HMDIAG_xxx naming,
so that we have a single nomenclature for these errors regardless of
whether threads are notified via SIGDEBUG or their observable
component.

The API rev. is bumped to #17 as a result of these changes.

      lib: introduce the interface to observables · f27fc993
      Philippe Gerum authored 
      

Since ABI 23, the core provides the new observable element, which
enables the observer design pattern. Any EVL thread is in and of
itself an observable which can be monitored for events too.

As a by-product, the poll interface can now be given a user-defined
opaque data when subscribing file descriptors to poll elements, which
the core passes back on return to evl_poll().
