The number of stick-counter entries usable by track-sc rules is currently set at build time. There is no good value for this since the vast majority of users don't need any, most need only a few and rare users need more. Adding more counters for everyone increases memory and CPU usages for no reason. This patch moves the per-session and per-stream arrays to a pool of a size defined at boot time. This way it becomes possible to set the number of entries at boot time via a new global setting "tune.stick-counters" that sets the limit for the whole process. When not set, the MAX_SESS_STR_CTR value still applies, or 3 if not set, as before. It is also possible to lower the value to 0 to save a bit of memory if not used at all. Note that a few low-level sample-fetch functions had to be protected due to the ability to use sample-fetches in the global section to set some variables. |
