[Linux-stable-mirror] Patch "e1000e: Fix e1000_check_for_copper_link_ich8lan return value." has been added to the 3.18-stable tree

by gregkh＠linuxfoundation.org

This is a note to let you know that I've just added the patch titled e1000e: Fix e1000_check_for_copper_link_ich8lan return value. to the 3.18-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=sum… The filename of the patch is: e1000e-fix-e1000_check_for_copper_link_ich8lan-return-value.patch and it can be found in the queue-3.18 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable(a)vger.kernel.org> know about it. >From 4110e02eb45ea447ec6f5459c9934de0a273fb91 Mon Sep 17 00:00:00 2001 From: Benjamin Poirier <bpoirier(a)suse.com> Date: Mon, 11 Dec 2017 16:26:40 +0900 Subject: e1000e: Fix e1000_check_for_copper_link_ich8lan return value. From: Benjamin Poirier <bpoirier(a)suse.com> commit 4110e02eb45ea447ec6f5459c9934de0a273fb91 upstream. e1000e_check_for_copper_link() and e1000_check_for_copper_link_ich8lan() are the two functions that may be assigned to mac.ops.check_for_link when phy.media_type == e1000_media_type_copper. Commit 19110cfbb34d ("e1000e: Separate signaling for link check/link up") changed the meaning of the return value of check_for_link for copper media but only adjusted the first function. This patch adjusts the second function likewise.

[Linux-stable-mirror] Patch "Bluetooth: Prevent stack info leak from the EFS element." has been added to the 3.18-stable tree

From: Ben Seri <ben(a)armis.com> commit 06e7e776ca4d36547e503279aeff996cbb292c16 upstream. In the function l2cap_parse_conf_rsp and in the function l2cap_parse_conf_req the following variable is declared without initialization: struct l2cap_conf_efs efs; In addition, when parsing input configuration parameters in both of these functions, the switch case for handling EFS elements may skip the memcpy call that will write to the efs variable: ... case L2CAP_CONF_EFS: if (olen == sizeof(efs)) memcpy(&efs, (void *)val, olen); ... The olen in the above if is attacker controlled, and regardless of that if, in both of these functions the efs variable would eventually be added to the outgoing configuration request that is being built: l2cap_add_conf_opt(&ptr, L2CAP_CONF_EFS, sizeof(efs), (unsigned long) &efs); So by sending a configuration request, or response, that contains an L2CAP_CONF_EFS element, but with an element length that is not sizeof(efs) - the memcpy to the uninitialized efs variable can be avoided, and the uninitialized variable would be returned to the attacker (16 bytes).

When using a GPIO which is high by default, and initialize the driver in USB Hub mode, initialization fails with: [ 111.757794] usb3503 0-0008: SP_ILOCK failed (-5) The reason seems to be that the chip is not properly reset. Probe does initialize reset low, however some lines later the code already set it back high, which is not long enouth. Make sure reset is asserted for at least 100us by inserting a delay after initializing the reset pin during probe.
