…y()` kind of "private". 'ipa_subdomains_server.c' still uses those, but ideally should be reworked to use `sss_child_start()` instead.
Issue spotted by 'o3' LLM: ``` sss_child_start builds a pipe pair, marks non-blocking using sss_fd_nonblocking but no error check of that helper. ```
Issue spotted by 'o3' LLM: ``` buf is allocated exactly PASSKEY_CHILD_MSG_CHUNK bytes; if the child writes a full 1024-byte, the string may miss a terminating NUL (read does not append one). Previously had the same flaw, but still worth fixing (allocate +1 or ensure NUL). ```
as it suits better.

Hi,
thank you very much for this long overdue effort. Codewise I'm fine and I run a couple of test with different child processes without issues. Some of them I run many times and checked for memory leaks without success. ACK.
bye,
Sumit

A set of patches with the main goal of getting rid of tons of code duplication around
fork() + exec(), setting up SIGCHLD and timeout handlers, etc.There are two (clearly marked) patches generated by LLM under strict supervision (multiple iterations for both patches) and two patches written as a result of review by LLM (also clearly marked).
There is further potential for improvements, most notably replacing direct
exec*()inipa_subdomains_server.candproxy_auth.c, but also unifying some typical callbacks (like timeout handler that usually simply ends tevent req). But this is already pretty large and I'd like to have it reviewed.
