| | | | | | | | | | | | | | | | | | | | | | | | In these Makefiles, at least one of "obj-y" and "obj-" is non-empty, hence built-in.o is always created without such a trick.

That was race-prone (somebody else might have had a reference to descriptor table and do fget() just as we'd been checking) and it had become flat-out incorrect back when we switched to fget_light() on those codepaths - unlike fget(), it doesn't grab an extra reference unless the descriptor table is shared. The same change allowed a race-free check, though - we are safe exactly when refcount is less than 2. It was a long time ago; pre-2.6.12 for ioctl() (the codepath leading to ppp one) and 2.6.17 for sendmsg() (netlink one). OTOH, netlink hadn't grown that check until 3.9 and ppp used to live in drivers/net, not drivers/net/ppp until 3.1. The bug existed well before that, though, and the same fix used to apply in old location of file. Cc: stable@vger.kernel.org Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>

However, it would appear as though the proper throttling is already in place for all possible ingress paths, and that the call is redundant. If packets are arriving from the physical NIC, we've already throttled them by this point. Otherwise, if they are coming via macvlan_queue_xmit(), it calls either 'dev_forward_skb()', which ends up calling netif_rx_internal(), or else in the broadcast case, we are throttling via macvlan_broadcast_enqueue(). The test results below are from off the box to an lxc instance running macvlan. Once the tranactions/sec stop increasing, the cpu idle time has gone to 0.

The HW will use the higher allowed response rate that is lower than the rate of the received frame. This is more or less what IEEE80211 mandates, but I missed the fact that IEEE80211 also says that whenever it happens that for a modulation class there is no any rate in the basic rates set, then the response rate set shall include also all the mandatory rates for that modulation class. This patch adds mandatory OFDM rates to the allowed response rate set if no OFDM rate is included in the basic rate set. Depending by the AP, I faced cases in which this patch seems to cause a noticeable perfomance improvement. - With my usual test AP there is no particular perfomance difference. - With a prism54/hostapd AP this patch causes RX thoughput increase from about 5Mbps to about 20Mbps. Hopefully this patch may help people that faced performance regression wrt the old staging driver. Signed-off-by: Andrea Merello <andrea.merello@gmail.com> Signed-off-by: John W.

This causes the next allocation to reuse an entry. When this happens in sunvdc, the server side vds driver begins nack'ing the messages and ends up resetting the ldc channel. This problem does not effect sunvnet since it checks for < 2. The fix here is to just never allocate the very last dring slot so that full and empty are not the same condition. The request start path was changed to check for the ring being full a bit earlier, and to stop the blk_queue if there is no space left. The blk_queue will be restarted once the ring is only half full again. The number of ring entries was increased to 512 which matches the sunvnet and Solaris vdc drivers, and greatly reduces the frequency of hitting the ring full condition and the associated blk_queue stop/starting. The checks in sunvent were adjusted to account for vio_dring_avail() returning 1 less. Orabug: 19441666 OraBZ: 14983 Signed-off-by: Dwight Engen <dwight.engen@oracle.com> Signed-off-by: David S.
