[S] Change in ...nfs-ganesha[next]: Normalize IPv4 addresses in hash_sockaddr() to match IPv4-mapped IPv6...

Suhas Athani has uploaded this change for review. ( https://review.gerrithub.io/c/ffilz/nfs-ganesha/+/1243948?usp=email ) Change subject: Normalize IPv4 addresses in hash_sockaddr() to match IPv4-mapped IPv6 form ...................................................................... Normalize IPv4 addresses in hash_sockaddr() to match IPv4-mapped IPv6 form `hash_sockaddr()` produces different hashes for the same IPv4 address depending on whether it's stored as `AF_INET` or IPv4-mapped IPv6 (`::ffff:a.b.c.d`). This breaks consistency in the client_mgr cache: NFS inserts using the mapped form, but RemoveClient clears using the plain IPv4 form, leaving a stale pointer after free. Problem: - `sockaddr_cmp()` treats both forms as equal (canonicalization on compare) - `hash_sockaddr()` did not normalize them the same way on little-endian hosts - RemoveClient cache invalidation misses, leaving freed entry accessible - Subsequent remount hits stale cache → use-after-free or crash in `sockaddr_cmp()` Solution: 1. Normalize `AF_INET` to IPv4-mapped IPv6 before hashing in `hash_sockaddr()` so both forms produce the same hash. 2. Use the stored client address hash in `remove_gsh_client()` for cache invalidation (defensive; now redundant but future-proof).

[S] Change in ...nfs-ganesha[next]: CEPH: Support ceph client pool for increased performance

Sachin Punadikar has uploaded this change for review. ( https://review.gerrithub.io/c/ffilz/nfs-ganesha/+/1243865?usp=email ) Change subject: CEPH: Support ceph client pool for increased performance ...................................................................... CEPH: Support ceph client pool for increased performance Currently Ganesha makes use single ceph client to interact with Ceph cluster. There is known limitation in libcephfs, which restrict performance of Ganesha. To overcome this, one can make use of multiple ceph clients. Attaching additional ceph clients can lead to more resource utilization. To limit such resource consumption, one can work with set of ceph clients. This change supports such ceph client pool, and it helps when you have more exports to serve.

SAL: restore NLM state owner refcount pairing commit-id: dc03cb3 removed inc/dec_state_owner_ref on state_t create/destroy. After NLM4_SHARE, the RPC drops its temporary owner ref while share state_t and share lists remain, freeing the owner and leaving a dangling state->state_owner (UAF on FREE_ALL/SM_NOTIFY cleanup). Restore inc_state_owner_ref() in state_nlm_share() and dec_state_owner_ref() in remove_nlm_share() so the owner lives for the lifetime of the state_t.
