Perfect, thanks for confirming, I am OK with the patch. For my case sll_halen = 0x6 but only first 4 byte of the sll_addr was the valid, so it was not the issue of size of sll_addr being 8, anyway it was quick dirty app, something should be wrong, I believe not need to dig it more. > > Igor > > On Fri, Apr 12, 2019 at 8:15 PM Ferruh Yigit wrote: > >> On 4/12/2019 6:12 PM, Igor Ryzhov wrote: >>> Hi Ferruh, >>> >>> I didn't test it with any special application, but FRR's ISIS works for >> me after >>> the patch, and it didn't work before. >> >> That is good enough, and by work you mean that you are able to get correct >> value >> on 'sll_addr', right? >> >>> >>> Igor >>> >>> On Fri, Apr 12, 2019 at 5:53 PM Ferruh Yigit >> > wrote: >>> >>> On 4/12/2019 3:52 PM, Ferruh Yigit wrote: >>> > On 4/10/2019 11:30 AM, Igor Ryzhov wrote: >>> >> It allows applications running packet sockets over KNI interfaces >> to get >>> >> source Ethernet addresses of packets received using recvfrom >> function. >>> >> >>> >> Signed-off-by: Igor Ryzhov > iryzhov@nfware.com>> >>> > >>> > Acked-by: Ferruh Yigit >> > >>> > >>> > >>> > Hi Igor, >>> > >>> > I tested this with a quick application on top of kni interfaces, >> that >>> reads and >>> > prints the 'sll_halen', but the last two bytes of the mac address >> are always >>> >>> I mean 'sll_addr', 'sll_halen' is right (6). >>> >>> > zero, it is quite possible that something is not right in the test >> app, but >>> > before spending any time on it, can you please confirm this is >> working >>> fine for you? >>> > >>> >> >>
