* usb: replace %p with %pKManu Gautam2018-11-271-6/+6
| | | | | | | | | | | | | | | Format specifier %p can leak kernel addresses while not valuing the kptr_restrict system settings. When kptr_restrict is set to (1), kernel pointers printed using the %pK format specifier will be replaced with 0's. Debugging Note : &pK prints only Zeros as address. If you need actual address information, write 0 to kptr_restrict. echo 0 > /proc/sys/kernel/kptr_restrict CRs-fixed: 1052849 Change-Id: I0e98145730380ea983fa8f46a28d15dd6c2c31df Signed-off-by: Manu Gautam <mgautam@codeaurora.org> Signed-off-by: Yasir Malik <ymalik@codeaurora.org> Signed-off-by: Kevin F.

* usb: dwc3: gadget: delay unmap of bounced requestsJanusz Dziedzic2017-07-041-4/+17
| | | | | | | | | | | | | commit de288e36fe33f7e06fa272bc8e2f85aa386d99aa upstream. In the case of bounced ep0 requests, we must delay DMA operation until after ->complete() otherwise we might overwrite contents of req->buf. This caused problems with RNDIS gadget.

* usb: dwc3: gadget: always unmap EP0 requestsFelipe Balbi2017-06-171-4/+4
| | | | | | | | | | | | | | | | | | | | commit d62145929992f331fdde924d5963ab49588ccc7d upstream. commit 0416e494ce7d ("usb: dwc3: ep0: correct cache sync issue in case of ep0_bounced") introduced a bug where we would leak DMA resources which would cause us to starve the system of them resulting in failing DMA transfers. Fix the bug by making sure that we always unmap EP0 requests since those are *always* mapped.

* usb: dwc3: gadget: increment request->actual onceFelipe Balbi2017-04-111-8/+11
| | | | | | | | | | | | | | | | commit c7de573471832dff7d31f0c13b0f143d6f017799 upstream. When using SG lists, we would end up setting request->actual to: num_mapped_sgs * (request->length - count) Let's fix that up by incrementing request->actual only once.
