* fbdev: zero-fill colormap in fbcmap.cPhillip Potter2021-04-101-4/+4
| | | | | | | | | | | | | | | | Use kzalloc() rather than kmalloc() for the dynamically allocated parts of the colormap in fb_alloc_cmap_gfp, to prevent a leak of random kernel data to userspace under certain circumstances. Fixes a KMSAN-found infoleak bug reported by syzbot at: https://syzkaller.appspot.com/bug?id=741578659feabd108ad9e06696f0c1f2e69c4b6e Reported-by: syzbot+47fa9c9c648b765305b9@syzkaller.appspotmail.com Cc: stable <stable@vger.kernel.org> Reviewed-by: Geert Uytterhoeven <geert+renesas@glider.be> Signed-off-by: Phillip Potter <phil@philpotter.co.uk> Link: https://lore.kernel.org/r/20210331220719.1499743-1-phil@philpotter.co.uk Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

* binder: tell userspace to dump current backtrace when detected oneway spammingHang Lu2021-04-105-8/+56
| | | | | | | | | | | | | | | | | | | | | When async binder buffer got exhausted, some normal oneway transactions will also be discarded and may cause system or application failures. By that time, the binder debug information we dump may not be relevant to the root cause. And this issue is difficult to debug if without the backtrace of the thread sending spam. This change will send BR_ONEWAY_SPAM_SUSPECT to userspace when oneway spamming is detected, request to dump current backtrace. Oneway spamming will be reported only once when exceeding the threshold (target process dips below 80% of its oneway space, and current process is responsible for either more than 50 transactions, or more than 50% of the oneway space). And the detection will restart when the async buffer has returned to a healthy state.

It can be used to safely handling the AXI traffic on a Reconfigurable Partition when it is undergoing dynamic reconfiguration and there by preventing system deadlock that may occur if AXI transactions are interrupted during reconfiguration. PR-Decoupler and AXI shutdown manager are completely different IPs. But both the IP registers are compatible and also both belong to the same sub-system (fpga-bridge).So using same driver for both IP's.

However this change is not backwards compatible, placing additional requirements onto qcom,sc7180-qmp-usb3-phy and qcom,sdm845-qmp-usb3-phy device nodes (to include separate DP part, etc). However the aforementioned nodes do not inclue DP part, they strictly follow the schema defined in the qcom,qmp-phy.yaml file. Move those compatibles, leaving qcom,qmp-usb3-dp-phy.yaml to describe only real "combo" USB3+DP device nodes.
