flush delay is used as an external storage for net.ipv4.route.flush sysctl entry. It is write-only. The ctl_table->data for this entry is used once. Fix this case to point to the stack to remove global variable. Do this to avoid additional variable on struct net in the next patch. Possible race (as it was before) accessing this local variable is removed using flush_mutex. Signed-off-by: NDenis V. Lunev <den@openvz.org> Signed-off-by: NDavid S. Miller <davem@davemloft.net>

The problem with introducing checksum offload and gso to tun is they need to set dev->features to enable GSO and/or checksumming, which is supposed to be done before register_netdevice(), ie. as part of TUNSETIFF. Unfortunately, TUNSETIFF has always just ignored flags it doesn't understand, so there's no good way of detecting whether the kernel supports new IFF_ flags. This patch implements a TUNGETFEATURES ioctl which returns all the valid IFF flags. It could be extended later to include other features. Here's an example program which uses it: #include <linux/if_tun.h> #include <sys/types.h> #include <sys/ioctl.h> #include <sys/stat.h> #include <fcntl.h> #include <err.h> #include <stdio.h> static struct { unsigned int flag; const char *name; } known_flags[] = { { IFF_TUN, "TUN" }, { IFF_TAP, "TAP" }, { IFF_NO_PI, "NO_PI" }, { IFF_ONE_QUEUE, "ONE_QUEUE" }, }; int main() { unsigned int features, i; int netfd = open("/dev/net/tun", O_RDWR); if (netfd < 0) err(1, "Opening /dev/net/tun"); if (ioctl(netfd, TUNGETFEATURES, &features) != 0) { printf("Kernel does not support TUNGETFEATURES, guessing\n"); features = (IFF_TUN|IFF_TAP|IFF_NO_PI|IFF_ONE_QUEUE); } printf("Available features are: "); for (i = 0; i < sizeof(known_flags)/sizeof(known_flags[0]); i++) { if (features & known_flags[i].flag) { features &= ~known_flags[i].flag; printf("%s ", known_flags[i].name); } } if (features) printf("(UNKNOWN %#x)", features); printf("\n"); return 0; } Signed-off-by: NRusty Russell <rusty@rustcorp.com.au> Acked-by: NMax Krasnyansky <maxk@qualcomm.com> Signed-off-by: NDavid S.

There are some places in TCP that select one MIB index to bump snmp statistics like this: if (<something>) NET_INC_STATS_BH(<some_id>); else if (<something_else>) NET_INC_STATS_BH(<some_other_id>); ... else NET_INC_STATS_BH(<default_id>); or in a more tricky but still similar way. On the other hand, this NET_INC_STATS_BH is a camouflaged increment of percpu variable, which is not that small. Factoring those cases out de-bloats 235 bytes on non-preemptible i386 config and drives parts of the code into 80 columns. add/remove: 0/0 grow/shrink: 0/7 up/down: 0/-235 (-235) function old new delta tcp_fastretrans_alert 1437 1424 -13 tcp_dsack_set 137 124 -13 tcp_xmit_retransmit_queue 690 676 -14 tcp_try_undo_recovery 283 265 -18 tcp_sacktag_write_queue 1550 1515 -35 tcp_update_reordering 162 106 -56 tcp_retransmit_timer 990 904 -86 Signed-off-by: NPavel Emelyanov <xemul@openvz.org> Signed-off-by: NDavid S.

This patch is the minimal amount of code needed to support wake-on-lan in platform mode properly (i.e. "ethtool -s eth0 wol g" is sufficient, no additional magic needed) for me. This is derived from David Brownells patch (http://lists.laptop.org/pipermail/devel/2007-April/004691.html). However I decided to move the hook into pci-acpi.c since the other two pci hooks also live there and pci and acpi are the only users of the platform_enable_wakeup-hook. As a 'side-effect' this also makes wake on usb activity work for me and I had to disable usb wakeup (which is enabled by default) using the power/wakeup sysfs functionality ("echo disabled > ${sysfs_path_to_device}/power/wakeup"). (BTW I first thought the 'immediate reboot because of usb wake' effect is caused by the optical mouse generating a wake event, but it rather seems to be a problem with a flaky secondary usb host controller, which sees a connected device where nothing is attached) Signed-off-by: NTobias Diedrich <ranma+kernel@tdiedrich.de> Signed-off-by: NJeff Garzik <jgarzik@redhat.com>

We currently don't signal the kernel we that this device can wake the system. Call device_init_wakeup() to correct this. Without this device_can_wakeup and device_may_wakeup will return incorrect values. Together with the minimized acpi wakeup patch (6/4 ;)), which will follow in the next mail, this really makes wake-on-lan work for me as expected (i.e. "ethtool -s eth0 wol g" is sufficient, no additional magic needed).

The call to e1000_clean_tx_irq in e1000_netpoll can race with the call to e1000_clean_tx_irq in e1000_clean. With a small bit of tweaking to to netpoll_send_skb to simulate a system that was under extreme stress, I was able to reproduce these concurrent calls. This can result in multiple frees to the skbs on the tx ring buffer. Dropping this call from e1000_netpoll should be fine since we can rely on the calls in e1000_clean to do what is needed since napi will poll the hardware just after calling poll_controller.

There is a missing "!" in a conditional statement which is causing entries to be skipped when dumping the default IPv6 static label entries. This can be demonstrated by running the following: # netlabelctl unlbl add default address:::1 \ label:system_u:object_r:unlabeled_t:s0 # netlabelctl -p unlbl list ... you will notice that the entry for the IPv6 localhost address is not displayed but does exist (works correctly, causes collisions when attempting to add duplicate entries, etc.).
