ATR support for UDP on 82599 needs to be redesigned, since the current model doesn't make much sense. The fallout from having it in though is it causes all UDP traffic to still compute the ATR hashes on transmit, which are useless. This removal will return upwards of 10% of relative computational overhead in forwarding tests. Signed-off-by:

When LRO is enabled, the received packet and byte counters represent the LRO'd packets, not the packets/bytes on the wire. The Intel 82599 NIC has registers that keep count of the physical packets. Add these counters to the ethtool stats. The byte counters are 36-bit, but the high 4 bits were being ignored in the 2.6.31 ixgbe driver: Read those as well to allow longer time between polling the stats to detect wraps. Signed-off-by:

Peter P Waskiewicz Jr authored
82599 has a different register offset for the Tx DCA control registers. We disable relaxed ordering of the descriptor writebacks for Tx head writeback, but didn't disable it properly for 82599. However, this shouldn't be a visible issue, since ixgbe doesn't use Tx head writeback. This patch just makes sure we're not doing blind writes to offsets we don't expect. Signed-off-by:

Since commit 9b22ea56 ( net: fix packet socket delivery in rx irq handler ) We lost rx timestamping of packets received on accelerated vlans. Effect is that tcpdump on real dev can show strange timings, since it gets rx timestamps too late (ie at skb dequeueing time, not at skb queueing time) 14:47:26.986871 IP 192.168.20.110 > 192.168.20.141: icmp 64: echo request seq 1 14:47:26.986786 IP 192.168.20.141 > 192.168.20.110: icmp 64: echo reply seq 1 14:47:27.986888 IP 192.168.20.110 > 192.168.20.141: icmp 64: echo request seq 2 14:47:27.986781 IP 192.168.20.141 > 192.168.20.110: icmp 64: echo reply seq 2 14:47:28.986896 IP 192.168.20.110 > 192.168.20.141: icmp 64: echo request seq 3 14:47:28.986780 IP 192.168.20.141 > 192.168.20.110: icmp 64: echo reply seq 3 Signed-off-by:

When requesting all prl entries (kprl.addr == INADDR_ANY) and there are more prl entries than there is space passed from userspace, the existing code would always copy cmax+1 entries, which is more than can be handled. This patch makes the kernel copy only exactly cmax entries. Signed-off-by:

"I recently (on a flight) I found out that when I boot with the hard-switch activated, so turning off all wireless activity on my laptop, the state is not correctly announced in /dev/rfkill (reading it with rfkill command, or my own gnome applet)... After turning off and on again the hard-switch the events were right." We can fix this by querying the firmware at load time and calling rfkill_set_hw_state(). Signed-off-by:

The move away from having drivers assign wireless handlers, in favour of making cfg80211 assign them, broke the sysfs registration (the wireless/ dir went missing) because the handlers are now assigned only after registration, which is too late. Fix this by special-casing cfg80211-based devices, all of which are required to have an ieee80211_ptr, in the sysfs code, and also using get_wireless_stats() to have the same values reported as in procfs.

The wireless extensions have a copy_from_user to a local stack array "essid", but both me and gcc have failed to find where the bounds for this copy are located in the code.

Multiple problems were reported due to interaction between wpa_supplicant and the wext compat code in cfg80211, which appear to be due to it not getting any bss pointer here when wpa_supplicant sets all parameters -- do that now. We should still get the bss after doing an extra scan, but that appears to increase the time we need for connecting enough to sometimes cause timeouts. Signed-off-by:

When hardware or uCode problem occurs driver captures significant information from device to enable debugging. The format of this information is different between 3945 and 4965 and later devices, yet currently the 3945 uses the 4965 and later format. Fix this by adding a new library call that is initialized to the correct formatting routine based on device. This moves the iwlagn event and error log handling back to iwl-agn.c to make it part of iwlagn module. Also remove the 3945 sysfs file that triggers dump of event log - there is already a debugfs file that can do it for all drivers. Signed-off-by:

We keep track of where to write into a buffer by keeping a count of how much has been written so far. When writing to the buffer we thus take the buffer pointer and adding the count of what has been written so far. Keeping track of what has been written so far is done by incrementing this number every time something is written to the buffer with how much has been written at that time. Currently this number is incremented incorrectly when using the "hex_dump_to_buffer" call to add data to the buffer. Fix this by only adding what has been added to the buffer in that call instead of what has been added since beginning of buffer.

The sys_socketcall() function has a very clever system for the copy size of its arguments. Unfortunately, gcc cannot deal with this in terms of proving that the copy_from_user() is then always in bounds. This is the last (well 9th of this series, but last in the kernel) such case around. With this patch, we can turn on code to make having the boundary provably right for the whole kernel, and detect introduction of new security accidents of this type early on. Signed-off-by:

This reverts commit 64506929. While the code does not actually break anything, it does not completely follow RFC5214 yet. After talking back with Fred L. Templin, I agree that completing the ISATAP specific RS/RA code, would pollute the kernel a lot with code that is better implemented in userspace. The kernel should not send RS packages for ISATAP at all. Signed-off-by:
