Pull smb client fixes from Paulo Alcantara:
 "A batch of bug fixes for the smb client:

   - Fix multiple out-of-bounds reads and use-after-frees in the SMB2/3
     receive path that are reachable from a malicious or compromised
     server: a stale next_buffer pointer and an integer overflow in
     compound encrypted frame handling, missing minimum-PDU-size and
     per-sub-PDU length validation before parsing command-specific
     response fields, missing bounds checks in DFS referral, server
     interface list, EA list, POSIX SID, snapshot enumeration and SMB1
     reparse point parsing

   - Fix use-after-frees and races in multichannel and connection
     teardown, including an interface freed while still in use when
     adding channels, a server used after its channel reference was
     dropped, a reconnect work item left queued after the server is
     freed and an uninitialized reconnect list node

   - Fix a heap overflow in the native symlink parser: an absolute
     target without an NT drive prefix caused out-of-bounds writes and a
     u16 length underflow leading to a 64K memcpy into a small buffer,
     triggerable by a user with write access to a mounted share under
     default settings

   - Fix WSL reparse point parsing: use unaligned accessors for the
     packed extended-attribute payload to avoid alignment faults on some
     architectures and stop leaving partially mutated fattr fields on
     parse failure

   - Fix lease break ACKs being sent through the wrong session on
     multiuser mounts, which caused read failures (e.g. on NetApp
     ONTAP/Azure Files) when copying files

   - Fix an smbd_connection leak when cifs_get_tcp_session() fails after
     an RDMA connection was already established"
