Windows: Fix possible false error message during device enumeration

During early phases of enumeration, it is possible for a device to be
enumerated before its parent. When this occurs, the device assigned as
the parent will actually be a grandparent. During later phases of

This commit deals with this by trying to reap as many transfers as possible
on disconnect on USBFS_CAP_REAP_AFTER_DISCONNECT capable kernels and then
calling usbi_handle_disconnect(handle) to deal with any remaining ones.

Chris Dickens [Mon, 26 Oct 2015 13:18:33 +0000 (14:18 +0100)]
core: Refactor code related to transfer flags and timeout handling

Commit a886bb02 sped up the library a bit by removing the serialization
of transfer submission with respect to the flying_transfers list, but
it introduced two separate issues.

1) A deadlock scenario is possible given the following sequence:

   - Thread A submits transfer with very short timeout (say 1ms)
     -> takes transfer->lock
     -> adds transfer to flying_transfers list and arms timerfd
     -> actually calls backend to submit transfer, but it fails
   <context switch>
   - Thread B is doing event handling and sees the timerfd trigger
     -> takes ctx->flying_transfers_lock
     -> finds the transfer above on the list
     -> calls libusb_cancel_transfer() for this transfer
       --> takes transfer->lock
   <context switch>
   - Thread A sees the transfer failed to submit
     -> removes transfer from flying_transfers list
       --> takes ctx->flying_transfers_lock (still holding transfer->lock)
   ** DEADLOCK **

2) The transfer state flags (e.g. submitting, in-flight) were protected
    by transfer->flags_lock, but the timeout-related flags were OR'ed in
    during timeout handling operations outside of the lock. This leads to
    the possibility that transfer state might get overwritten.

This change corrects these issues and simplifies the transfer submission
code a bit by separating the state and timeout flags into their own flag
variables. The state flags are protected by the transfer lock. The timeout
flags are protected by the flying_transfers_lock.

The transfer submission code sheds some weight because it no longer needs
to worry about the timing of events that modify the transfer state flags.
These flags are always viewed and modified under the protection of the
transfer lock. Since libusb_submit_transfer() holds the transfer lock for
the entire duration of the operation, the other code paths that would
possibly touch the transfer (e.g. usbi_handle_disconnect() and
usbi_handle_transfer_completion()) have to wait for transfer submission
to fully complete. This eliminates any possible race conditions.

core: Change event handling lock to traditional (non-recursive) type

called by a thread that is handling events (e.g. from within a
transfer or hotplug callback). With commit 960a6e75, it is possible to

Steinar H. Gunderson [Sat, 20 Feb 2016 11:26:12 +0000 (12:26 +0100)]
Add support for persistent device memory.

Add a function to allocate memory belonging to a specific device,
so that the operating system can DMA straight into it for zerocopy,
and also avoid some clearing. Also, this allows up-front memory
allocation in the kernel at program startup; memory allocation is
otherwise done per-transfer, which can fail in a system where memory has become
fragmented over time).

This mirrors new functionality going into Linux' USB stack (recently
reviewed and acked upstream); only Linux is supported as a backend
currently.

[Chris Dickens] Modified to fix doxygen documentation, correct parameter
naming, reposition function declarations, and address a missing request
during the patch review process.

reference leak but introduced a false warning message that occurs

In addition, the condition variable timed-wait function has been modified
to accept the relative time passed in via libusb_wait_for_event(). This
allows the implementation-specific code to handle conversion to absolute
time as necessary, rather than forcing this to occur.
