Why: Commit 3ee31a8d0 added shared named ratelimit support (ratelimit.name + ratelimitNewFromConfig) but only wired it into imtcp, imptcp, and imudp. Seven modules with existing ratelimit.interval/ratelimit.burst support were left without the ability to reference shared ratelimit() objects. Impact: Adds ratelimit.name parameter to omfwd, omelasticsearch, omhttp, imhttp, imjournal, imklog, and imuxsock. Existing configurations remain unchanged. Before: These seven modules could only use inline ratelimit.interval/ratelimit.burst parameters. After: All modules can now reference shared ratelimit() configuration objects via ratelimit.name. Technical Overview: For each module, the same pattern from the imudp reference implementation is applied: - Add uchar *pszRatelimitName to config struct - Add ratelimit.name to cnfparamdescr - Change interval/burst defaults to -1 (sentinel) - Parse ratelimit.name in config handler - Add mutual-exclusivity check (name vs interval/burst) - Branch ratelimiter creation on pszRatelimitName: if set, call ratelimitNewFromConfig(); else legacy path - Free pszRatelimitName in destructor imuxsock is the most complex: it supports both per-socket ratelimit.name and syssock.ratelimit.name, with the per-source hashtable ratelimiter path also updated. imklog uses legacy parameter names (ratelimitinterval, ratelimitburst) but the new parameter uses the dotted form (ratelimit.name) for consistency. Each module receives a parameter doc page, module doc update, and a config-validation test.
