%p will leak kernel pointers, so let's not expose the information on dmesg and instead use %pK. %pK will only show the actual addresses if explicitly enabled under /proc/sys/kernel/kptr_restrict.
Signed-off-by: Felipe Balbi <[email protected]> --- Inspired by a recent patch Greg posted. Note that I've kept tracepoints with %p because you already need admin rights to mount tracefs and/or debugfs. If folks think tracepoints should be changed to %pK too, let me know and I'll change the patch. drivers/usb/dwc3/dwc3-st.c | 2 +- drivers/usb/dwc3/gadget.c | 9 +++------ 2 files changed, 4 insertions(+), 7 deletions(-) diff --git a/drivers/usb/dwc3/dwc3-st.c b/drivers/usb/dwc3/dwc3-st.c index dfbf464eb88c..505676fd3ba4 100644 --- a/drivers/usb/dwc3/dwc3-st.c +++ b/drivers/usb/dwc3/dwc3-st.c @@ -230,7 +230,7 @@ static int st_dwc3_probe(struct platform_device *pdev) dwc3_data->syscfg_reg_off = res->start; - dev_vdbg(&pdev->dev, "glue-logic addr 0x%p, syscfg-reg offset 0x%x\n", + dev_vdbg(&pdev->dev, "glue-logic addr 0x%pK, syscfg-reg offset 0x%x\n", dwc3_data->glue_base, dwc3_data->syscfg_reg_off); dwc3_data->rstc_pwrdn = diff --git a/drivers/usb/dwc3/gadget.c b/drivers/usb/dwc3/gadget.c index 750364eb11e1..011ac3ccfbe7 100644 --- a/drivers/usb/dwc3/gadget.c +++ b/drivers/usb/dwc3/gadget.c @@ -1224,12 +1224,9 @@ static int __dwc3_gadget_ep_queue(struct dwc3_ep *dep, struct dwc3_request *req) return -ESHUTDOWN; } - if (WARN(req->dep != dep, "request %p belongs to '%s'\n", - &req->request, req->dep->name)) { - dev_err(dwc->dev, "%s: request %p belongs to '%s'\n", - dep->name, &req->request, req->dep->name); + if (WARN(req->dep != dep, "request %pK belongs to '%s'\n", + &req->request, req->dep->name)) return -EINVAL; - } pm_runtime_get(dwc->dev); @@ -1387,7 +1384,7 @@ static int dwc3_gadget_ep_dequeue(struct usb_ep *ep, } goto out1; } - dev_err(dwc->dev, "request %p was not queued to %s\n", + dev_err(dwc->dev, "request %pK was not queued to %s\n", request, ep->name); ret = -EINVAL; goto out0; -- 2.11.0.295.gd7dffce1ce -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
