From 506ada89629ec7059b96ecfb0dc7d33ece0103ca Mon Sep 17 00:00:00 2001 From: Eduard Zingerman Date: Fri, 4 Sep 2026 17:05:56 -0700 Subject: bpf: mark a NULL kfunc argument precise check_kfunc_arg() allows bpf_register_is_null() for nullable arguments w/o marking the underlying scalar register precise. Hence a checkpoint created on such a path would prune against arbitrary scalar value. Fixes: 3bda08b63670 ("bpf: Allow NULL buffers in bpf_dynptr_slice(_rw)") Signed-off-by: Eduard Zingerman Link: https://lore.kernel.org/r/20260904-register-is-null-precise-fixes-v1-5-0f5a360ff15d@gmail.com Signed-off-by: Alexei Starovoitov --- Documentation/usb/usb-help.rst | 17 +++++++++++++++++ 1 file changed, 17 insertions(+) create mode 100644 Documentation/usb/usb-help.rst (limited to 'Documentation/usb/usb-help.rst') diff --git a/Documentation/usb/usb-help.rst b/Documentation/usb/usb-help.rst new file mode 100644 index 000000000..dc23ecd4d --- /dev/null +++ b/Documentation/usb/usb-help.rst @@ -0,0 +1,17 @@ +============== +USB references +============== + +2008-Mar-7 + +For USB help other than the readme files that are located in +`Documentation/usb/*`, see the following: + +- Linux-USB project: http://www.linux-usb.org + mirrors at http://usb.in.tum.de/linux-usb/ + and http://it.linux-usb.org +- Linux USB Guide: http://linux-usb.sourceforge.net +- Linux-USB device overview (working devices and drivers): + http://www.qbik.ch/usb/devices/ + +The Linux-USB mailing list is at linux-usb@vger.kernel.org -- cgit v1.3.1
