      vfs: Undo an overly zealous MS_RDONLY -> SB_RDONLY conversion · a9e5b732
      David Howells authored
      In do_mount() when the MS_* flags are being converted to MNT_* flags,
      MS_RDONLY got accidentally convered to SB_RDONLY.
      
      Undo this change.
      
      Fixes: e462ec50 ("VFS: Differentiate mount flags (MS_*) from internal superblock flags")

      afs: Fix server record deletion · 66062592
      David Howells authored
      AFS server records get removed from the net->fs_servers tree when
      they're deleted, but not from the net->fs_addresses{4,6} lists, which
      can lead to an oops in afs_find_server() when a server record has been
      removed, for instance during rmmod.
      
      Fix this by deleting the record from the by-address lists before posting
      it for RCU destruction.
      
      The reason this hasn't been noticed before is that the fileserver keeps
      probing the local cache manager, thereby keeping the service record
      alive, so the oops would only happen when a fileserver eventually gets
      bored and stops pinging or if the module gets rmmod'd and a call comes
      in from the fileserver during the window between the server records
      being destroyed and the socket being closed.
      
      The oops looks something like:
      
        BUG: unable to handle kernel NULL pointer dereference at 000000000000001c
        ...
        Workqueue: kafsd afs_process_async_call [kafs]

      We want it only for the stuff created by SB_KERNMOUNT mounts, *not* for
      their copies.  As it is, creating a deep stack of bindings of /proc/*/ns/*
      somewhere in a new namespace and exiting yields a stack overflow.
