[M] Change in ...nfs-ganesha[next]: Idmapper: Limit max user-groups cache entries, and add a fifo queue

by Dipit Grover (GerritHub)

Dipit Grover has uploaded this change for review. ( https://review.gerrithub.io/c/ffilz/nfs-ganesha/+/1177651?usp=email ) Change subject: Idmapper: Limit max user-groups cache entries, and add a fifo queue ...................................................................... Idmapper: Limit max user-groups cache entries, and add a fifo queue This change limits the max number of user-groups entries in the uid2grp cache. The limit is configurable through the DIRECTORY_SERVICES section in Ganesha config. The cache eviction strategy is determined using the fifo queue. The fifo queue order mimics the order of expiration time of the cache entries, since expiration time is a linear function of the insertion time -- expiration_time = insertion_time + cache_validity (constant) The head of the queue therefore contains the entry with least time-validity, and the tail of the queue contains the entry with most time-validity. The eviction happens from the head, and insertion happens at the tail.

[L] Change in ...nfs-ganesha[next]: Idmapper: Introduce negative cache for group entries

by Dipit Grover (GerritHub)

Dipit Grover has uploaded this change for review.

Idmapper: Introduce negative cache for group entries This change introduces a negative cache for storing group entries that failed idmapping. The validity and max-count of such entries is derived from the DIRECTORY_SERVICES section of the Ganesha config. This cache is maintained separately from positive cache, to allow for independent operation, configuration and maintenance. To avoid code duplication, this CL generalises the existing code for negative user cache and adapts it for both negative user and negative group entities.

[M] Change in ...nfs-ganesha[next]: Idmapper: Introduce reaper to remove expired user, group cache entries

by Dipit Grover (GerritHub)

Dipit Grover has uploaded this change for review. ( https://review.gerrithub.io/c/ffilz/nfs-ganesha/+/1177643?usp=email ) Change subject: Idmapper: Introduce reaper to remove expired user, group cache entries ...................................................................... Idmapper: Introduce reaper to remove expired user, group cache entries This change adds cache reaper functionality for the user and group caches. The reaper runs periodically and removes the expired cache entries. The reaper execution interval is configurable through the Ganesha config. Note that the default value of this execution interval is currently set to about ten years, which basically means that the reaper is disabled. It will be enabled in the future based on the cache performance in production.
