The debugfs commands that dump hex information are not doing these as expected viz. "lldp get local", "nvm read", "dump debug fwdata", etc. Use print_hex_dump() instead to hex dump and remove the print buffer stuff from the code. Change-Id: I507bd8b2187aae8bad5055b7872978c309cf143e Signed-off-by:

Valgrind found that extracted labels that are passed from the lexer weren't freed upon exit. Therefore, add a small helper function that walks label tables and frees them. Since also NULL can be passed to free(3), we do not need to take care of that here. While at it, fix up a spacing error in bpf_set_curr_label(). Signed-off-by:

We must not leave the socket intact in bpf_runnable(). The socket is used to test if the filter code is being accepted by the kernel or not. So right after we do the setsockopt(2), we need to close it again. Signed-off-by:

Tom Herbert says: ==================== net: Add rxhash utility hash functions v3: There's really nothing specific about rxhash that constrains it to be a value just for these receive path. Drop the 'rx' part in utility functions, including skb_get_rxhash. In subsequent patches, we can change the rxhash and l4_rxhash names also, as well as abstracting out the interface to the hash. Added comments about hash types per feedback. In this version I'm omitting the changes to drivers to make the patch set manageable. Will add those changes in followup pathes. ----- This patch series introduce skb_set_rxhash and skb_clear_rxhash which are called to set the rxhash (from network drivers) and to clear the rxhash. This API should be used instead of updating fields in the skbuff directly. ==================== Signed-off-by: -

In several places 'skb->rxhash = 0' is being done to clear the rxhash value in an skb. This does not clear l4_rxhash which could still be set so that the rxhash wouldn't be recalculated on subsequent call to skb_get_rxhash. This patch adds an explict function to clear all the rxhash related information in the skb properly. skb_clear_hash_if_not_l4 clears the rxhash only if it is not marked as l4_rxhash. Fixed up places where 'skb->rxhash = 0' was being called. Signed-off-by:

While investigating performance problems on small RPC workloads, I noticed linux TCP stack was always splitting the last TSO skb into two parts (skbs). One being a multiple of MSS, and a small one with the Push flag. This split is done even if TCP_NODELAY is set, or if no small packet is in flight. Example with request/response of 4K/4K IP A > B: . ack 68432 win 2783 <nop,nop,timestamp 6524593 6525001> IP A > B: . 65537:68433(2896) ack 69632 win 2783 <nop,nop,timestamp 6524593 6525001> IP A > B: P 68433:69633(1200) ack 69632 win 2783 <nop,nop,timestamp 6524593 6525001> IP B > A: . ack 68433 win 2768 <nop,nop,timestamp 6525001 6524593> IP B > A: . 69632:72528(2896) ack 69633 win 2768 <nop,nop,timestamp 6525001 6524593> IP B > A: P 72528:73728(1200) ack 69633 win 2768 <nop,nop,timestamp 6525001 6524593> IP A > B: . ack 72528 win 2783 <nop,nop,timestamp 6524593 6525001> IP A > B: . 69633:72529(2896) ack 73728 win 2783 <nop,nop,timestamp 6524593 6525001> IP A > B: P 72529:73729(1200) ack 73728 win 2783 <nop,nop,timestamp 6524593 6525001> We can avoid this split by including the Nagle tests at the right place. Note : If some NIC had trouble sending TSO packets with a partial last segment, we would have hit the problem in GRO/forwarding workload already. tcp_minshall_update() is moved to tcp_output.c and is updated as we might feed a TSO packet with a partial last segment. This patch tremendously improves performance, as the traffic now looks like : IP A > B: . ack 98304 win 2783 <nop,nop,timestamp 6834277 6834685> IP A > B: P 94209:98305(4096) ack 98304 win 2783 <nop,nop,timestamp 6834277 6834685> IP B > A: . ack 98305 win 2768 <nop,nop,timestamp 6834686 6834277> IP B > A: P 98304:102400(4096) ack 98305 win 2768 <nop,nop,timestamp 6834686 6834277> IP A > B: . ack 102400 win 2783 <nop,nop,timestamp 6834279 6834686> IP A > B: P 98305:102401(4096) ack 102400 win 2783 <nop,nop,timestamp 6834279 6834686> IP B > A: . ack 102401 win 2768 <nop,nop,timestamp 6834687 6834279> IP B > A: P 102400:106496(4096) ack 102401 win 2768 <nop,nop,timestamp 6834687 6834279> IP A > B: . ack 106496 win 2783 <nop,nop,timestamp 6834280 6834687> IP A > B: P 102401:106497(4096) ack 106496 win 2783 <nop,nop,timestamp 6834280 6834687> IP B > A: . ack 106497 win 2768 <nop,nop,timestamp 6834688 6834280> IP B > A: P 106496:110592(4096) ack 106497 win 2768 <nop,nop,timestamp 6834688 6834280> Before : lpq83:~# nstat >/dev/null;perf stat ./super_netperf 200 -t TCP_RR -H lpq84 -l 20 -- -r 4K,4K 280774 Performance counter stats for './super_netperf 200 -t TCP_RR -H lpq84 -l 20 -- -r 4K,4K': 205719.049006 task-clock # 9.278 CPUs utilized 8,449,968 context-switches # 0.041 M/sec 1,935,997 CPU-migrations # 0.009 M/sec 160,541 page-faults # 0.780 K/sec 548,478,722,290 cycles # 2.666 GHz [83.20%] 455,240,670,857 stalled-cycles-frontend # 83.00% frontend cycles idle [83.48%] 272,881,454,275 stalled-cycles-backend # 49.75% backend cycles idle [66.73%] 166,091,460,030 instructions # 0.30 insns per cycle # 2.74 stalled cycles per insn [83.39%] 29,150,229,399 branches # 141.699 M/sec [83.30%] 1,943,814,026 branch-misses # 6.67% of all branches [83.32%] 22.173517844 seconds time elapsed lpq83:~# nstat | egrep "IpOutRequests|IpExtOutOctets" IpOutRequests 16851063 0.0 IpExtOutOctets 23878580777 0.0 After patch : lpq83:~# nstat >/dev/null;perf stat ./super_netperf 200 -t TCP_RR -H lpq84 -l 20 -- -r 4K,4K 280877 Performance counter stats for './super_netperf 200 -t TCP_RR -H lpq84 -l 20 -- -r 4K,4K': 107496.071918 task-clock # 4.847 CPUs utilized 5,635,458 context-switches # 0.052 M/sec 1,374,707 CPU-migrations # 0.013 M/sec 160,920 page-faults # 0.001 M/sec 281,500,010,924 cycles # 2.619 GHz [83.28%] 228,865,069,307 stalled-cycles-frontend # 81.30% frontend cycles idle [83.38%] 142,462,742,658 stalled-cycles-backend # 50.61% backend cycles idle [66.81%] 95,227,712,566 instructions # 0.34 insns per cycle # 2.40 stalled cycles per insn [83.43%] 16,209,868,171 branches # 150.795 M/sec [83.20%] 874,252,952 branch-misses # 5.39% of all branches [83.37%] 22.175821286 seconds time elapsed lpq83:~# nstat | egrep "IpOutRequests|IpExtOutOctets" IpOutRequests 11239428 0.0 IpExtOutOctets 23595191035 0.0 Indeed, the occupancy of tx skbs (IpExtOutOctets/IpOutRequests) is higher : 2099 instead of 1417, thus helping GRO to be more efficient when using FQ packet scheduler.

These function to manipulate multiple addresses are not used anywhere in current net-next tree. Some out of tree code maybe using these but too bad; they should submit their code upstream.. Also, make __hw_addr_flush local since only used by dev_addr_lists.c Signed-off-by:

John W. Linville says: ==================== Please pull this batch of updates for the 3.14 stream... For the Bluetooth bits, Gustavo says: "This is the first batch of patches intended for 3.14. There is nothing big here. Most of the code are refactors, clean up, small fixes, plus some new device id support." And... "More patches to 3.14. Here we have the support for Low Energy Connection Oriented Channels (LE CoC). Basically, as the name says, this adds supports for connection oriented channels in the same way we already have them for BR/EDR connections so profiles/protocols that work on top of BR/EDR can now work on LE plus a plenty of new possibilities for LE." For the ath10k bits, Kalle says: "Janusz and Marek implemented DFS support to ath10k, but the code is not enabled yet due to missing cfg80211/mac80211 patches (it will be enabled in the next pull request). Michal did some device reset fixes and made it possible for ath10k to share an interrupt with another device. And lots of smaller fixes from different people." For the iwlwifi bits, Emmanuel says: "I have here a big rework of the rate control by Eyal. This is obviously the biggest part of this batch. I also have enhancement of protection flags by Avri and a few bits for WoWLAN by Eliad and Luca. Johannes cleans up the debugfs plus a few fixes. I provided a few things for Bluetooth coexistence. Besides this we have an implementation for low priority scan." Along with all that, there are big batches of updates to mwifiex and ath9k, Jeff Kirsher's FSF address fix patches, and a handful of other bits here and there. Please let me know if there are problems! ==================== Signed-off-by: -

Sebastian Hesselbarth says: ==================== net: phy: Ethernet PHY powerdown optimization This is v2 of the ethernet PHY power optimization patches to reduce power consumption of network PHYs with link that are either unused or the corresponding netdev is down. Compared to the last version, this patch set drops a patch to disable unused PHYs after late initcall, as it is not compatible with a modular mdio bus [1]. I'll investigate different ways to have a modular mdio bus driver get notified when driver loading is done. Again, a branch with v2 applied to v3.13-rc2 can also be found at https://github.com/shesselba/linux-dove.git topic/ethphy-power-v2 [1] http://www.spinics.net/lists/arm-kernel/msg293028.html ==================== Signed-off-by:
