Hi, I have found with netlink we can miss a ack message when exchanging large buffers. I came across this "bug ?" when doing some tests on the NFC subsytem by trying to send extended APDU to a secure element (up to 65K) or when sending specific device firmware data (up to 8K) (NFC_ATTR_SE_APDU & NFC_ATTR_VENDOR_DATA).
After some search on the web, i found this topic was already threated by Jiri Benc in November 2013: - http://patchwork.ozlabs.org/patch/290976/ - http://www.spinics.net/lists/netdev/msg256938.html I haven't found any update or any fix in recent kernel. I liked the netlink message cap approach. Do you have any update ? Do you think a netlink message cap in netlink_ack in case of an error is an acceptable approach ?
