(I think I sent this to linux-net-owner instead of to the list... if not, then please forgive the duplicatation.) Ok...I'm using the generic PPP layer and want to write the PPP frame to a socket. So, my start_xmit() extracts the data from the sk_buff and passes it to the socket's sendmsg function. This calls ip_build_xmit(), which ultimately calls alloc_skb(). Now, alloc_skb() has issues...it says it has to be called atomically. It checks this by calling testing (in_interrupt() && (gfp_msk & GFP_WAIT)). in_interrupt() returns true if we're in a BH context. So....what's up with that? I've got to be missing something, cuz these two sources can't be *that* far off from each other. Plus the fact that PPPoE doesn't seem to have any trouble calling alloc_skb() from its start_xmit(). Can anyone set me straight here? There's a cookie in it for you if you do :) -- Gary Cote gcote@transat-tech.com - : send the line "unsubscribe linux-net" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
