@ceolin - feel like a re-review? This is mostly the same as the previous PR, just rebased. |

This PR now includes a commit from #77104, to mitigate false-positive Coding Guideline checks. That PR should preferably be merged before this. |

Newlib requires an alias for the getpid() function. There was a Kconfig already present for doing so, but the actual alias was missing. So this is technically a bugfix. Signed-off-by: Chris Friedt <[email protected]>
Since Zephyr itself does not currently support processes, but conformant applications should still be able to link, add stubs for the remaining POSIX functions in the POSIX_SIGNALS Option Group. The POSIX_SIGNALS Option Group is required for PSE51, PSE52, PSE53, PSE54, and likely many other POSIX Subprofiles. Signed-off-by: Chris Friedt <[email protected]>
Add tests for the presence of items in the POSIX SIGNALS Option Group. Signed-off-by: Chris Friedt <[email protected]>
Mark the POSIX_SIGNALS Option Group as supported to the extent possible under Zephyr, as Zephyr does not yet support processes. Signed-off-by: Chris Friedt <[email protected]>

This is a resubmission of #74436.
There seems to have been an oversight in #75244 in that these commits (belonging neither to #73978 nor #74096) were reverted. No justification was made for PR #74436 to be reverted, so presumably it was an accident.
Indeed, all testing passed with this PR in
mainas well as against thev3.7.0tag. Also ran through CI successfully with the expanded testing in #76377.Since Zephyr itself does not currently support processes, but conformant applications should still be able to link, add stubs for the remaining POSIX functions in the
