  ksmbd: return complete and aligned stream information (2026-10-28
17:57:07 +0900)

----------------------------------------------------------------
 - Fix compound CREATE response buffer sizing and reserve space for final
   response padding to prevent buffer overflows and out-of-bounds reads.

 - Allocate sufficient space for UTF-16 directory-name conversion,
   including the terminating NUL.

 - Fix an RDMA transfer length underflow that can cause out-of-bounds
   reads or writes when processing multiple remote buffer descriptors.

 - Fix use-after-free bugs during failed durable reconnect cleanup and
   AppInstanceId supersede racing with session teardown.

 - Keep retry timeout clamp bounds constant to fix a MIPS build
   failure with CONFIG_HZ=1024.

 - Fix a session reference leak in compounded SESSION_SETUP and reject
   compounded session binding to avoid mixing session and tree state
   after a failed binding.

 - Serialize operations on each named pipe and preserve unread RPC reply
   data for subsequent READ requests when the client's output buffer is
   too small.

 - Return complete, eight-byte-aligned stream information entries and
   report insufficient output space correctly.

 - Use the resolved share root path so shares rooted at mount points
   list their contents correctly with crossmnt disabled.

 - Ignore network-device events outside the initial network namespace,
   preventing container interfaces from affecting ksmbd listeners.
