kqueue tests: Add file and line info to some test failure output

2022-06-08T00:42:18Z

This brings us slightly closer to upstream and is useful when debugging test failures. Sponsored by: The FreeBSD Foundation (cherry picked from commit c728c56c870abe230e45cee5c477f0d890ebacef)

Make whitespace more consistent in libkqueue tests.

2018-11-27T15:12:34Z

After r337820, which "corrected" some spaces-instead-of-tab whitespace issues in the libkqueue tests, jmg@ pointed out that these files were originally space-based, not tab-spaced, and so the correction should have been to get rid of the tabs that had been introduced in previous changes, not the spaces. This change does that. This is a whitespace only change; no functional change is intended. Reported by: jmg@ MFC after: 3 days Sponsored by: Dell EMC Isilon

A follow-up to r337812 to catch a couple more memory leaks that should have been included in that change. Reported by: Coverity CID: 1296064, 1296067 (for real this time) MFC after: 3 days X-MFC-with: r337812 Sponsored by: Dell EMC

Fix several memory leaks.

2018-08-14T19:12:45Z

The libkqueue tests have several places that leak memory by using an idiom like: puts(kevent_to_str(kevp)); Rework to save the pointer returned from kevent_to_str() and then free() it after it has been used.

Allow a EVFILT_TIMER kevent to be updated.

2018-07-27T13:49:17Z

If a timer is updated (re-added) with a different time period (specified in the .data field of the kevent), the new time period has no effect; the timer will not expire until the original time has elapsed. This violates the documented behavior as the kqueue(2) man page says (in part) "Re-adding an existing event will modify the parameters of the original event, and not result in a duplicate entry." This modification, adapted from a patch submitted by cem@ to PR214987, fixes the kqueue system to allow updating a timer entry. The kevent timer behavior is changed to: * When a timer is re-added, update the timer parameters to and re-start the timer using the new parameters. * Allow updating both active and already expired timers. * When the timer has already expired, dequeue any undelivered events and clear the count of expirations. All of these changes address the original PR and also bring the FreeBSD and macOS kevent timer behaviors into agreement. A few other changes were made along the way: * Update the kqueue(2) man page to reflect the new timer behavior. * Fix man page style issues in kqueue(2) diagnosed by igor. * Update the timer libkqueue system test to test for the updated timer behavior. * Fix the (test) libkqueue common.h file so that it includes config.h which defines various HAVE_* feature defines, before the #if tests for such variables in common.h. This enables the use of the actual err(3) family of functions. * Fix the usages of the err(3) functions in the tests for incorrect type of variables. Those were formerly undiagnosed due to the disablement of the err(3) functions (see previous bullet point).

Add abstime kqueue(2) timers and expand struct kevent members.

2017-06-17T00:57:26Z

This change implements NOTE_ABSTIME flag for EVFILT_TIMER, which specifies that the data field contains absolute time to fire the event. To make this useful, data member of the struct kevent must be extended to 64bit. Using the opportunity, I also added ext members. This changes struct kevent almost to Apple struct kevent64, except I did not changed type of ident and udata, the later would cause serious API incompatibilities. The type of ident was kept uintptr_t since EVFILT_AIO returns a pointer in this field, and e.g. CHERI is sensitive to the type (discussed with brooks, jhb). Unlike Apple kevent64, symbol versioning allows us to claim ABI compatibility and still name the new syscall kevent(2). Compat shims are provided for both host native and compat32.
