Prevent transfer from being submitted twice or improperly canceled

This ensures that tpriv->urbs and tpriv->iso_urbs are always set to NULL
whenever a transfer is not submitted.  In this way, submit_*_transfer()
and cancel_*_transfer() can error check to ensure that the transfer is
in the correct state to be either submitted or canceled, preventing
potential memory leaks or double frees.

15 years agoLinux: Fix race condition in cancel_bulk_transfer()
David Moore [Thu, 8 Jan 2009 06:31:09 +0000 (22:31 -0800)]
Linux: Fix race condition in cancel_bulk_transfer()

This fixes a race condition in cancel_bulk_transfer().  In the old
version, awaiting_reap and awaiting_discard are incremented in
cancel_bulk_transfer() and decremented in handle_bulk_completion().
However, since these events may take place in two different threads,
these variables may reach zero before all URBs have been canceled,
triggered spurious callbacks and duplicate frees.

This changes the logic to use a single variable "num_retired" to replace
both awaiting_reap and awaiting_discard.  num_retired is incremented
only in handle_bulk_completion() and thus there is no race.  The handler
will know that all URBs have been canceled when num_retired becomes
equal to num_urbs.

This change also simplifies a great deal of the logic in both functions
and is a net reduction in the amount of code.

Note that some variables such as "reap_action" probably need to still be
protected by a mutex, and this patch does not address that issue.

Pause event handling while opening and closing devices

Ludovic Rousseau found that crashes often occur if you close a device
while another thread is doing event handling.

Fix this by adding an internal control pipe, which the close routines
use to interrupt the event handler and obtain the event handling lock,
ensuring that no other thread is handling events while the device is
closed. After the close completes, it signals all the event handlers
to start up again using the usual mechanism.

Also modified libusb_open() to do a similar thing, so that event
handlers are interrupted in order to realise that a new poll fd has
appeared.
