Hi, all
If some message went into bus->wqueue, and failed to run
ioctl(KDBUS_CMD_SEND) and returned r < 0,
I found that this message will remain in the bus->wqueue. If the peer is
killed for some reason, this message will fail to be sent and remain in the
wqueu for ever.
Because in dispatch_wqueue() , when bus_write_message() return r <0,
dispatch_wqueue() will simply return this "r " into the caller.
And the wqueue is invisible to user application, so user application also
cannot remove this message to handle this error case.
I wonder whether this is a problem, and if yes, should we remove this message
in dispatch_wqueue() when r < 0 ?
Thanks a lot !
Li Cheng
