Subject: [PATCH 0/5] smb:client: fix possible use after free problems
Date: Mon,  4 Aug 2025 14:10:11 +0200	[thread overview]
Message-ID: <cover.1754308712.git.metze@samba.org> (raw)

While refactoring the client and server smbdirect code I
noticed a few problems where we might hit use after free
style problems.

In order to allow backports I decided to fix the problems
before trying to move things to common code.

The server has similar problems, I'll send a separate
patchset for the server as they are independed.

Stefan Metzmacher (5):
  smb: client: let send_done() cleanup before calling
    smbd_disconnect_rdma_connection()
  smb: client: remove separate empty_packet_queue
  smb: client: make sure we call ib_dma_unmap_single() only if we called
    ib_dma_map_single already
  smb: client: let recv_done() cleanup before notifying the callers.
  smb: client: let recv_done() avoid touching data_transfer after
    cleanup/move
