+Subject: mac80211: Send EAPOL frames at lowest rate
+
+From: Jouni Malinen <jouni@qca.qualcomm.com>
+
+commit 9c1c98a3bb7b7593b60264b9a07e001e68b46697 upstream.
+
+The current minstrel_ht rate control behavior is somewhat optimistic in
+trying to find optimum TX rate. While this is usually fine for normal
+Data frames, there are cases where a more conservative set of retry
+parameters would be beneficial to make the connection more robust.
+
+EAPOL frames are critical to the authentication and especially the
+EAPOL-Key message 4/4 (the last message in the 4-way handshake) is
+important to get through to the AP. If that message is lost, the only
+recovery mechanism in many cases is to reassociate with the AP and start
+from scratch. This can often be avoided by trying to send the frame with
+more conservative rate and/or with more link layer retries.
+
+In most cases, minstrel_ht is currently using the initial EAPOL-Key
+frames for probing higher rates and this results in only five link layer
+transmission attempts (one at high(ish) MCS and four at MCS0). While
+this works with most APs, it looks like there are some deployed APs that
+may have issues with the EAPOL frames using HT MCS immediately after
+association. Similarly, there may be issues in cases where the signal
+strength or radio environment is not good enough to be able to get
+frames through even at couple of MCS 0 tries.
+
+The best approach for this would likely to be to reduce the TX rate for
+the last rate (3rd rate parameter in the set) to a low basic rate (say,
+6 Mbps on 5 GHz and 2 or 5.5 Mbps on 2.4 GHz), but doing that cleanly
+requires some more effort. For now, we can start with a simple one-liner
+that forces the minimum rate to be used for EAPOL frames similarly how
+the TX rate is selected for the IEEE 802.11 Management frames. This does
+result in a small extra latency added to the cases where the AP would be
+able to receive the higher rate, but taken into account how small number
+of EAPOL frames are used, this is likely to be insignificant. A future
+optimization in the minstrel_ht design can also allow this patch to be
+reverted to get back to the more optimized initial TX rate.
+
+It should also be noted that many drivers that do not use minstrel as
+the rate control algorithm are already doing similar workarounds by
+forcing the lowest TX rate to be used for EAPOL frames.

+
+From: Johan Hovold <johan@kernel.org>
+
+commit 2c3fbe3cf28fbd7001545a92a83b4f8acfd9fa36 upstream.
+
+In case an infinite timeout (0) is requested, the irda wait_until_sent
+implementation would use a zero poll timeout rather than the default
+200ms.
+
+Note that wait_until_sent is currently never called with a 0-timeout
+argument due to a bug in tty_wait_until_sent.

+Subject: TTY: fix tty_wait_until_sent on 64-bit machines
+
+From: Johan Hovold <johan@kernel.org>
+
+commit 79fbf4a550ed6a22e1ae1516113e6c7fa5d56a53 upstream.
+
+Fix overflow bug in tty_wait_until_sent on 64-bit machines, where an
+infinite timeout (0) would be passed to the underlying tty-driver's
+wait_until_sent-operation as a negative timeout (-1), causing it to
+return immediately.
+
+This manifests itself for example as tcdrain() returning immediately,
+drivers not honouring the drain flags when setting terminal attributes,
+or even dropped data on close as a requested infinite closing-wait
+timeout would be ignored.
+
+The first symptom was reported by Asier LLANO who noted that tcdrain()
+returned prematurely when using the ftdi_sio usb-serial driver.
+
+Fix this by passing 0 rather than MAX_SCHEDULE_TIMEOUT (LONG_MAX) to the
+underlying tty driver.
+
+Note that the serial-core wait_until_sent-implementation is not affected
+by this bug due to a lucky chance (comparison to an unsigned maximum
+timeout), and neither is the cyclades one that had an explicit check for
+negative timeouts, but all other tty drivers appear to be affected.

+
+commit 96e5d31244c5542f5b2ea81d76f14ba4b8a7d440 upstream.
+
+In the wrapper the IRQ disable should be done by writing 1's to the
+IRQ*_CLR register. Existing code is broken because it instead writes
+zeros to IRQ*_SET register.
+
+Fix this by adding functions dwc3_omap_write_irqmisc_clr() and
+dwc3_omap_write_irq0_clr() which do the right thing.

+From: Max Mansfield <max.m.mansfield@gmail.com>
+
+commit c7d373c3f0da2b2b78c4b1ce5ae41485b3ef848c upstream.
+
+This patch integrates Cyber Cortex AV boards with the existing
+ftdi_jtag_quirk in order to use serial port 0 with JTAG which is
+required by the manufacturers' software.
+
+Steps: 2
+
+[ftdi_sio_ids.h]
+1. Defined the device PID
+
+[ftdi_sio.c]
+2. Added a macro declaration to the ids array, in order to enable the
+jtag quirk for the device.

+Make sure to handle an infinite timeout (0).
+
+Note that wait_until_sent is currently never called with a 0-timeout

+
+From: Johan Hovold <johan@kernel.org>
+
+commit 07fdfc5e9f1c966be8722e8fa927e5ea140df5ce upstream.
+
+Fix return value in probe error path, which could end up returning
+success (0) on errors. This could in turn lead to use-after-free or
+double free (e.g. in port_remove) when the port device is removed.

+commit ca4383a3947a83286bc9b9c598a1f55e867871d7 upstream.
+
+Add missing error handling when registering the tty device at port

+when the port device is removed.

+Subject: USB: usbfs: don't leak kernel data in siginfo
+
+From: Alan Stern <stern@rowland.harvard.edu>
+
+commit f0c2b68198589249afd2b1f2c4e8de8c03e19c16 upstream.
+
+When a signal is delivered, the information in the siginfo structure
+is copied to userspace. Good security practice dicatates that the
+unused fields in this structure should be initialized to 0 so that
+random kernel stack data isn't exposed to the user. This patch adds
+such an initialization to the two places where usbfs raises signals.

+Subject: xhci: Allocate correct amount of scratchpad buffers
+
+From: Mathias Nyman <mathias.nyman@linux.intel.com>
+
+commit 6596a926b0b6c80b730a1dd2fa91908e0a539c37 upstream.
+
+Include the high order bit fields for Max scratchpad buffers when
+calculating how many scratchpad buffers are needed.
+
+I'm suprised this hasn't caused more issues, we never allocated more than
+32 buffers even if xhci needed more. Either we got lucky and xhci never
+really used past that area, or then we got enough zeroed dma memory anyway.
+
+Should be backported as far back as possible

+Subject: xhci: fix reporting of 0-sized URBs in control endpoint
+
+From: Aleksander Morgado <aleksander@aleksander.es>
+
+commit 45ba2154d12fc43b70312198ec47085f10be801a upstream.
+
+When a control transfer has a short data stage, the xHCI controller generates
+two transfer events: a COMP_SHORT_TX event that specifies the untransferred
+amount, and a COMP_SUCCESS event. But when the data stage is not short, only the
+COMP_SUCCESS event occurs. Therefore, xhci-hcd must set urb->actual_length to
+urb->transfer_buffer_length while processing the COMP_SUCCESS event, unless
+urb->actual_length was set already by a previous COMP_SHORT_TX event.
+
+The driver checks this by seeing whether urb->actual_length == 0, but this alone
+is the wrong test, as it is entirely possible for a short transfer to have an
+urb->actual_length = 0.
+
+This patch changes the xhci driver to rely on a new td->urb_length_set flag,
+which is set to true when a COMP_SHORT_TX event is received and the URB length
+updated at that stage.
+
+This fixes a bug which affected the HSO plugin, which relies on URBs with
+urb->actual_length == 0 to halt re-submitting the RX URB in the control
+endpoint.
