check_curl fix: populate the dns cache when hostname gets resolved locally (#2280)

2026-06-17T21:26:04Z

* check_curl fix: populate the dns cache when hostname gets resolved locally due to a previous refactor, it would populate it when hostname wasnt getting resolved locally hostname_gets_resolved locally now assumes that resolving is local if proxy was unknown. previously was returning 0 instead of true, contradicting what it says fix a memory leak. server_address_clean was being assigned to another strndup result before being freed fix another memory leak, one path to return in hostname_gets_resolved_locally was not freeing up two variables improve logs and comments around hostname_gets_resolved_locally clang-format is applied * check_curl: fix typo in comment --------- Co-authored-by: Ahmet Oeztuerk

Check ntp time delay (#2277)

2026-06-11T00:40:07Z

* check_ntp_time: add polling delay NTP server can have rate limiting which might be triggered by check_ntp_time due to many requests in a short time span. This patch adds a default delay (of 0.5s) between requests to each server and a command line option (--poll-delay) to make this delay configurable. Co-authored-by: Lorenz Kästle * check_ntp_time: verify whether socket path fits into address struct check_ntp_time could be give a too long (>108 bytes) socket path to work with, which would potentially crash the program. This patch validates to length beforehand and stops execution in that case. Co-authored-by: Lorenz Kästle --------- Co-authored-by: Paul Crawford Co-authored-by: Lorenz Kästle
