2018-04-30ipv6: sr: extract the right key values for "seg6_make_flowlabel"Ahmed Abdelsalam
The seg6_make_flowlabel() is used by seg6_do_srh_encap() to compute the flowlabel from a given skb. It relies on skb_get_hash() which eventually calls __skb_flow_dissect() to extract the flow_keys struct values from the skb. In case of IPv4 traffic, calling seg6_make_flowlabel() after skb_push(), skb_reset_network_header(), and skb_mac_header_rebuild() will results in flow_keys struct of all key values set to zero. This patch calls seg6_make_flowlabel() before resetting the headers of skb to get the right key values. Extracted Key values are based on the type inner packet as follows: 1) IPv6 traffic: src_IP, dst_IP, L4 proto, and flowlabel of inner packet. 2) IPv4 traffic: src_IP, dst_IP, L4 proto, src_port, and dst_port 3) L2 traffic: depends on what kind of traffic carried into the L2 frame. IPv6 and IPv4 traffic works as discussed 1) and 2) Here a hex_dump of struct flow_keys for IPv4 and IPv6 traffic 10.100.1.100: 47302 > 30.0.0.2: 5001 00000000: 14 00 02 00 00 00 00 00 08 00 11 00 00 00 00 00 00000010: 00 00 00 00 00 00 00 00 13 89 b8 c6 1e 00 00 02 00000020: 0a 64 01 64 fc00:a1:a > b2::2 00000000: 28 00 03 00 00 00 00 00 86 dd 11 00 99 f9 02 00 00000010: 00 00 00 00 00 00 00 00 00 00 00 00 00 b2 00 00 00000020: 00 00 00 00 00 00 00 00 00 00 00 02 fc 00 00 a1 00000030: 00 00 00 00 00 00 00 00 00 00 00 0a Signed-off-by: Ahmed Abdelsalam <amsalam20@gmail.com> Signed-off-by: David S.

2018-04-30i40e: fix reading LLDP configurationMariusz Stachura
Previous method for reading LLDP config was based on hard-coded offsets. It happened to work, because of structured architecture of the NVM memory. In the new approach, known as FLAT, we need to calculate the absolute address, instead of using relative values. Needed defines for memory location were added.

2018-04-30tracepoint: Do not warn on ENOMEMMathieu Desnoyers
Tracepoint should only warn when a kernel API user does not respect the required preconditions (e.g. same tracepoint enabled twice, or called to remove a tracepoint that does not exist). Silence warning in out-of-memory conditions, given that the error is returned to the caller. This ensures that out-of-memory error-injection testing does not trigger warnings in tracepoint.c, which were seen by syzbot.

2018-04-30dm bufio: fix buffer alignmentMikulas Patocka
Commit 6b5e718cc138 ("dm bufio: relax alignment constraint on slab cache") relaxed alignment on dm-bufio cache, however it may break dm-crypt or dm-integrity. dm-crypt and dm-integrity require that the size of bio vector entries (bv_len) is aligned on its sector size. bv_offset doesn't have to be aligned, but bv_len must be. XFS sends unaligned bios, but they do not cross page boundary, so the requirement for aligned bv_len is met. Commit 6b5e718cc138 made dm-bufio send unaligned bios that cross page boundary, this could break dm-crypt and dm-integrity. Reinstates the alignment. Note that misaligned entries only happen when we use slab/slub debugging. Without debugging, the entries are always aligned.

2018-04-30erspan: auto detect truncated packets.William Tu
Currently the truncated bit is set only when the mirrored packet is larger than mtu. For certain cases, the packet might already been truncated before sending to the erspan tunnel. In this case, the patch detect whether the IP header's total length is larger than the actual skb->len. If true, this indicated that the mirrored packet is truncated and set the erspan truncate bit. I tested the patch using bpf_skb_change_tail helper function to shrink the packet size and send to erspan tunnel.

2018-04-30i40evf: Replace GFP_ATOMIC with GFP_KERNEL in i40evf_add_vlanJia-Ju Bai
i40evf_add_vlan() is never called in atomic context. i40evf_add_vlan() is only called by i40evf_vlan_rx_add_vid(), which is only set as ".ndo_vlan_rx_add_vid" in struct net_device_ops. ".ndo_vlan_rx_add_vid" is not called in atomic context. Despite never getting called from atomic context, i40evf_add_vlan() calls kzalloc() with GFP_ATOMIC, which does not sleep for allocation. GFP_ATOMIC is not necessary and can be replaced with GFP_KERNEL, which can sleep and improve the possibility of sucessful allocation. This is found by a static analysis tool named DCNS written by myself. And I also manually check it.

2018-04-30r8169: move common initializations to tp->hw_startHeiner Kallweit
The chip-specific init code includes quite some calls which are identical for all chips. So move these calls to tp->hw_start().

2018-04-30r8169: simplify rtl_hw_start_8169Heiner Kallweit
Currently done: - if mac_version in (01, 02, 03, 04) RTL_W8(tp, ChipCmd, CmdTxEnb | CmdRxEnb); - if mac_version in (01, 02, 03, 04) rtl_set_rx_tx_config_registers(tp); - if mac_version not in (01, 02, 03, 04) RTL_W8(tp, ChipCmd, CmdTxEnb | CmdRxEnb); rtl_set_rx_tx_config_registers(tp); So we do exactly the same independent of chip version and can simplify the code. In addition remove the call to rtl_init_rxcfg(), it's called in rtl_init_one() already and the set bits are never touched later. rtl_init_8168/8101 don't include this call either.

tp->cp_cmd is supposed to reflect the current value of the CplusCmd register. Several (quite old) changes however directly change this register w/o updating tp->cp_cmd. Also we have places in the code reading this register where we could use the cached value. In addition: - Properly initialize tp->cmd with the register value. - In rtl_hw_start_8169 remove one setting of PCIMulRW because it's set unconditionally anyway a few lines later. - In rtl_hw_start_8168 properly mask out the INTT bits before setting INTT_1.

RxChkSum and RxVlan aren't touched outside __rtl8169_set_features (except in probe), so they are always in sync with dev->features. And the RxConfig flags are set in rtl_set_rx_mode() which is called via dev_set_rx_mode() from __dev_open(). Therefore we can safely remove this call.

2018-04-30net: wireless: b43legacy: Replace GFP_ATOMIC with GFP_KERNEL in dma_tx_fragmentJia-Ju Bai
dma_tx_fragment() is never called in atomic context. dma_tx_fragment() is only called by b43legacy_dma_tx(), which is only called by b43legacy_tx_work(). b43legacy_tx_work() is only set a parameter of INIT_WORK() in b43legacy_wireless_init(). Despite never getting called from atomic context, dma_tx_fragment() calls alloc_skb() with GFP_ATOMIC, which does not sleep for allocation. GFP_ATOMIC is not necessary and can be replaced with GFP_KERNEL, which can sleep and improve the possibility of sucessful allocation. This is found by a static analysis tool named DCNS written by myself. And I also manually check it. Signed-off-by: Jia-Ju Bai <baijiaju1990@gmail.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
