Nithin Nayak Sujir says: ==================== This series adds support for modifying EEE settings via ethtool. Since this can impact Link Flap Avoidance, the driver pulls the current hardware settings if LFA is enabled. This is similar to how we do the link settings to avoid a flap. v2: Fixes pointed out by Ben Hutchings. - Use MDIO_AN_EEE_LPABLE to set the lp_advertised field. - Check that tx_lpi_timer is within valid range. ==================== Signed-off-by: NDavid S.

eee_config_ok() was checking only for mismatch in advertised settings. This patch expands the scope of eee_config_ok() to check for mismatch in the other eee settings.

Add tg3_eee_pull_config() to pull the settings from the hardware and populate the eee structure. If Link Flap Avoidance is enabled, we pull the eee settings from the hw so as not to cause a phy reset on eee config mismatch later. This requires moving down tg3_setup_eee() below the tg3_pull_config() to not trample existing settings.

hpa bringed into my attention some security related issues with BPF JIT on x86. This patch makes sure the bpf generated code is marked read only, as other kernel text sections. It also splits the unused space (we vmalloc() and only use a fraction of the page) in two parts, so that the generated bpf code not starts at a known offset in the page, but a pseudo random one.

tcp_timeout_skb() was intended to trigger fast recovery on timeout, unfortunately in reality it often causes spurious retransmission storms during fast recovery. The particular sign is a fast retransmit over the highest sacked sequence (SND.FACK). Currently the RTO timer re-arming (as in RFC6298) offers a nice cushion to avoid spurious timeout: when SND.UNA advances the sender re-arms RTO and extends the timeout by icsk_rto. The sender does not offset the time elapsed since the packet at SND.UNA was sent. But if the next (DUP)ACK arrives later than ~RTTVAR and triggers tcp_fastretrans_alert(), then tcp_timeout_skb() will mark any packet sent before the icsk_rto interval lost, including one that's above the highest sacked sequence. Most likely a large part of scorebard will be marked. If most packets are not lost then the subsequent DUPACKs with new SACK blocks will cause the sender to continue to retransmit packets beyond SND.FACK spuriously. Even if only one packet is lost the sender may falsely retransmit almost the entire window. The situation becomes common in the world of bufferbloat: the RTT continues to grow as the queue builds up but RTTVAR remains small and close to the minimum 200ms. If a data packet is lost and the DUPACK triggered by the next data packet is slightly delayed, then a spurious retransmission storm forms. As the original comment on tcp_timeout_skb() suggests: the usefulness of this feature is questionable. It also wastes cycles walking the sack scoreboard and is actually harmful because of false recovery. It's time to remove this.

This patch adds the support of peer address for IPv6. For example, it is possible to specify the remote end of a 6inY tunnel. This was already possible in IPv4: ip addr add ip1 peer ip2 dev dev1 The peer address is specified with IFA_ADDRESS and the local address with IFA_LOCAL (like explained in include/uapi/linux/if_addr.h). Note that the API is not changed, because before this patch, it was not possible to specify two different addresses in IFA_LOCAL and IFA_REMOTE. There is a small change for the dump: if the peer is different from ::, IFA_ADDRESS will contain the peer address instead of the local address.

The commit 823aa873 Author: stephen hemminger <stephen@networkplumber.org> Date: Sat Apr 27 11:31:57 2013 +0000 vxlan: allow choosing destination port per vxlan introduced per-vxlan UDP port configuration but only did half of the necessary work. It added per vxlan destination for sending, but overlooked the handling of multiple ports for incoming traffic. This patch changes the listening port management to handle multiple incoming UDP ports. The earlier per-namespace structure is now a hash list per namespace. It is also now possible to define the same virtual network id but with different UDP port values which can be useful for migration.

qlge allocates chunks from a page that it maps and unmaps that page when the last chunk is released. When the driver is unloaded or the card is removed, all chunks are released and the page is unmapped for the last chunk. However, when the last chunk of a page is not allocated and the device is removed, that page is not unmapped. In fact, its last reference is not put and there's also a page leak. This bug prevents a device from being properly hotplugged. When the DMA API debug option is enabled, the following messages show the pending DMA allocation after we remove the driver. This patch fixes the bug by unmapping and putting the page from the ring if its last chunk has not been allocated. pci 0005:98:00.0: DMA-API: device driver has pending DMA allocations while released from device [count=1] One of leaked entries details: [device address=0x0000000060a80000] [size=65536 bytes] [mapped with DMA_FROM_DEVICE] [mapped as page] ------------[ cut here ]------------ WARNING: at lib/dma-debug.c:746 Modules linked in: qlge(-) rpadlpar_io rpaphp pci_hotplug fuse [last unloaded: qlge] NIP: c0000000003fc3ec LR: c0000000003fc3e8 CTR: c00000000054de60 REGS: c0000003ee9c74e0 TRAP: 0700 Tainted: G O (3.7.2) MSR: 8000000000029032 <SF,EE,ME,IR,DR,RI> CR: 28002424 XER: 00000001 SOFTE: 1 CFAR: c0000000007a39c8 TASK = c0000003ee8d5c90[8406] 'rmmod' THREAD: c0000003ee9c4000 CPU: 31 GPR00: c0000000003fc3e8 c0000003ee9c7760 c000000000c789f8 00000000000000ee GPR04: 0000000000000000 00000000000000ef 0000000000004000 0000000000010000 GPR08: 00000000000000be c000000000b22088 c000000000c4c218 00000000007c0000 GPR12: 0000000028002422 c00000000ff26c80 0000000000000000 000001001b0f1b40 GPR16: 00000000100cb9d8 0000000010093088 c000000000cdf910 0000000000000001 GPR20: 0000000000000000 c000000000dbfc00 0000000000000000 c000000000dbfb80 GPR24: c0000003fafc9d80 0000000000000001 000000000001ff80 c0000003f38f7888 GPR28: c000000000ddfc00 0000000000000400 c000000000bd7790 c000000000ddfb80 NIP [c0000000003fc3ec] .dma_debug_device_change+0x22c/0x2b0 LR [c0000000003fc3e8] .dma_debug_device_change+0x228/0x2b0 Call Trace: [c0000003ee9c7760] [c0000000003fc3e8] .dma_debug_device_change+0x228/0x2b0 (unreliable) [c0000003ee9c7840] [c00000000079a098] .notifier_call_chain+0x78/0xf0 [c0000003ee9c78e0] [c0000000000acc20] .__blocking_notifier_call_chain+0x70/0xb0 [c0000003ee9c7990] [c0000000004a9580] .__device_release_driver+0x100/0x140 [c0000003ee9c7a20] [c0000000004a9708] .driver_detach+0x148/0x150 [c0000003ee9c7ac0] [c0000000004a8144] .bus_remove_driver+0xc4/0x150 [c0000003ee9c7b60] [c0000000004aa58c] .driver_unregister+0x8c/0xe0 [c0000003ee9c7bf0] [c0000000004090b4] .pci_unregister_driver+0x34/0xf0 [c0000003ee9c7ca0] [d000000002231194] .qlge_exit+0x1c/0x34 [qlge] [c0000003ee9c7d20] [c0000000000e36d8] .SyS_delete_module+0x1e8/0x290 [c0000003ee9c7e30] [c0000000000098d4] syscall_exit+0x0/0x94 Instruction dump: 7f26cb78 e818003a e87e81a0 e8f80028 e9180030 796b1f24 78001f24 7d6a5a14 7d2a002a e94b0020 483a7595 60000000 <0fe00000> 2fb80000 40de0048 80120050 ---[ end trace 4294f9abdb01031d ]--- Mapped at: [<d000000002222f54>] .ql_update_lbq+0x384/0x580 [qlge] [<d000000002227bd0>] .ql_clean_inbound_rx_ring+0x300/0xc60 [qlge] [<d0000000022288cc>] .ql_napi_poll_msix+0x39c/0x5a0 [qlge] [<c0000000006b3c50>] .net_rx_action+0x170/0x300 [<c000000000081840>] .__do_softirq+0x170/0x300 Signed-off-by: NThadeu Lima de Souza Cascardo <cascardo@linux.vnet.ibm.com> Acked-by: NJitendra Kalsaria <Jitendra.kalsaria@qlogic.com> Signed-off-by: NDavid S.
