We have a situation where the userspace client is writing to the sysfs to update the power and since the callback function exists the client receives the return value as count and considers the operation to be successful. That is correct as the write to the sysfs was successful. But there is no way to know if the actual operation was done or not. backlight_update_status() returns the error code if it fails. Pass that to the userspace client who is trying to update the power so that the client knows that the operation failed.

Patch "arp: honour gratuitous ARP _replies_" has been added to the 4.9-stable tree

by gregkh＠linuxfoundation.org

This is a note to let you know that I've just added the patch titled arp: honour gratuitous ARP _replies_ to the 4.9-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: arp-honour-gratuitous-arp-_replies_.patch and it can be found in the queue-4.9 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 foo@baz Mon Apr 9 17:09:24 CEST 2018 From: Ihar Hrachyshka <ihrachys(a)redhat.com> Date: Tue, 16 May 2017 07:53:43 -0700 Subject: arp: honour gratuitous ARP _replies_ From: Ihar Hrachyshka <ihrachys(a)redhat.com> [ Upstream commit 23d268eb240954e6e78f7cfab04f2b1e79f84489 ] When arp_accept is 1, gratuitous ARPs are supposed to override matching entries irrespective of whether they arrive during locktime. This was implemented in commit 56022a8fdd87 ("ipv4: arp: update neighbour address when a gratuitous arp is received and arp_accept is set") There is a glitch in the patch though. RFC 2002, section 4.6, "ARP, Proxy ARP, and Gratuitous ARP", defines gratuitous ARPs so that they can be either of Request or Reply type. Those Reply gratuitous ARPs can be triggered with standard tooling, for example, arping -A option does just that. This patch fixes the glitch, making both Request and Reply flavours of gratuitous ARPs to behave identically. As per RFC, if gratuitous ARPs are of Reply type, their Target Hardware Address field should also be set to the link-layer address to which this cache entry should be updated. The field is present in ARP over Ethernet but not in IEEE 1394. In this patch, I don't consider any broadcasted ARP replies as gratuitous if the field is not present, to conform the standard. It's not clear whether there is such a thing for IEEE 1394 as a gratuitous ARP reply; until it's cleared up, we will ignore such broadcasts. Note that they will still update existing ARP cache entries, assuming they arrive out of locktime time interval. Signed-off-by: Ihar Hrachyshka <ihrachys(a)redhat.com> Signed-off-by: David S.
