Blue flame is a latency enhancement feature that allows the driver to write the packet data directly to the NIC's registers thus making the read of the packet data from host memory redundant. We maintain a quota for the blue flame which is reloaded whenever we identify that the hardware is processing send requests and processes them fast enough so by the time we post the next send request it was able to process all the pending ones. This indicates that the hardware is capable of processing more blue flame requests efficiently. The blue flame quota is decremented whenever we send using blue flame. The current code erroneously clears the budget if we did not use blue flame for the current post send operation and we fix it here.

In RoCE, the RDMA-CM needs the node guid to establish connection between nodes. Today, the node guid exposed to mlx5 Ethernet VFs is zero, therefore RDMA-CM on the VF is broken. Whenever the administrator sets a MAC for a VF, derive the node guid from it and set it as well in the following way: MAC: e4:1d:2d:b3:f4:01 -> node_guid: e4:1d:2d:ff:fe:b3:f4:01 Fixes: 77256579 ('net/mlx5: E-Switch, Introduce Vport...')

Reorder vport enable flow to mark the vport as enabled before calling the vport change handler which was modified to handle the case for when vport is not enabled. This fixes the case for when the PF netdev is open before sriov is enabled, once sriov is enabled at esw_enable_vport, esw_vport_change_handle_locked didn't read the PF context since it thought the PF vport was not enabled. When we enable the vport, arming for events is not required anymore, since it's done on the vport change handle Fixes: 586cfa7f ('net/mlx5: E-Switch, Use vport event handler for vport cleanup') Signed-off-by:

The mlx5 flow-steering API (mlx5_create_flow_table/group/rule) never returns null pointer on error. Even if it was doing that, checking for IS_ERR_OR_NULL(p) and then returning PTR_ERR(p) would have cause bugs, since PTR_ERR(NULL) --> success, crash. To make things more robust and protect against related future bugs, convert all IS_ERR_OR_NULL checks on returned values to IS_ERR.

When a port is created following a split / unsplit we need to map it to the correct module and lane, enable it and then continue to initialize its various parameters such as MTU and VLAN filters. Under certain conditions, such as trying to split ports at the bottom row of the front panel by four, we get firmware errors. After evaluating this with the firmware team it was decided to alter the split / unsplit flow, so that first all the affected ports are mapped, then enabled and finally each is initialized separately. Fix the split / unsplit flow by first mapping and enabling all the affected ports. Newer firmware versions will support both flows.

iwpriv app uses iw_point structure to send data to Kernel. The iw_point structure holds a pointer. For compatibility Kernel converts the pointer as required for WEXT IOCTLs (SIOCIWFIRST to SIOCIWLAST). Some drivers may use iw_handler_def.private_args to populate iwpriv commands instead of iw_handler_def.private. For those case, the IOCTLs from SIOCIWFIRSTPRIV to SIOCIWLASTPRIV will follow the path ndo_do_ioctl(). Accordingly when the filled up iw_point structure comes from 32 bit iwpriv to 64 bit Kernel, Kernel will not convert the pointer and sends it to driver. So, the driver may get the invalid data. The pointer conversion for the IOCTLs (SIOCIWFIRSTPRIV to SIOCIWLASTPRIV), which follow the path ndo_do_ioctl(), is mandatory. This patch adds pointer conversion from 32 bit to 64 bit and vice versa, if the ioctl comes from 32 bit iwpriv to 64 bit Kernel. Cc: stable@vger.kernel.org Signed-off-by:

At present we perform an xfrm_lookup() for each UDPv6 message we send. The lookup involves querying the flow cache (flow_cache_lookup) and, in case of a cache miss, creating an XFRM bundle. If we miss the flow cache, we can end up creating a new bundle and deriving the path MTU (xfrm_init_pmtu) from on an already transformed dst_entry, which we pass from the socket cache (sk->sk_dst_cache) down to xfrm_lookup(). This can happen only if we're caching the dst_entry in the socket, that is when we're using a connected UDP socket. To put it another way, the path MTU shrinks each time we miss the flow cache, which later on leads to incorrectly fragmented payload. It can be observed with ESPv6 in transport mode: 1) Set up a transformation and lower the MTU to trigger fragmentation # ip xfrm policy add dir out src ::1 dst ::1 \ tmpl src ::1 dst ::1 proto esp spi 1 # ip xfrm state add src ::1 dst ::1 \ proto esp spi 1 enc 'aes' 0x0b0b0b0b0b0b0b0b0b0b0b0b0b0b0b0b # ip link set dev lo mtu 1500 2) Monitor the packet flow and set up an UDP sink # tcpdump -ni lo -ttt & # socat udp6-listen:12345,fork /dev/null & 3) Send a datagram that needs fragmentation with a connected socket # perl -e 'print "@" x 1470 | socat - udp6:[::1]:12345 2016/06/07 18:52:52 socat[724] E read(3, 0x555bb3d5ba00, 8192): Protocol error 00:00:00.000000 IP6 ::1 > ::1: frag (0|1448) ESP(spi=0x00000001,seq=0x2), length 1448 00:00:00.000014 IP6 ::1 > ::1: frag (1448|32) 00:00:00.000050 IP6 ::1 > ::1: ESP(spi=0x00000001,seq=0x3), length 1272 (^ ICMPv6 Parameter Problem) 00:00:00.000022 IP6 ::1 > ::1: ESP(spi=0x00000001,seq=0x5), length 136 4) Compare it to a non-connected socket # perl -e 'print "@" x 1500' | socat - udp6-sendto:[::1]:12345 00:00:40.535488 IP6 ::1 > ::1: frag (0|1448) ESP(spi=0x00000001,seq=0x6), length 1448 00:00:00.000010 IP6 ::1 > ::1: frag (1448|64) What happens in step (3) is: 1) when connecting the socket in __ip6_datagram_connect(), we perform an XFRM lookup, miss the flow cache, create an XFRM bundle, and cache the destination, 2) afterwards, when sending the datagram, we perform an XFRM lookup, again, miss the flow cache (due to mismatch of flowi6_iif and flowi6_oif, which is an issue of its own), and recreate an XFRM bundle based on the cached (and already transformed) destination. To prevent the recreation of an XFRM bundle, avoid an XFRM lookup altogether whenever we already have a destination entry cached in the socket. This prevents the path MTU shrinkage and brings us on par with UDPv4. The fix also benefits connected PINGv6 sockets, another user of ip6_sk_dst_lookup_flow(), who also suffer messages being transformed twice. Joint work with Hannes Frederic Sowa.

This patch fixed the following crash: BUG: unable to handle kernel NULL pointer dereference at 0000000000000028 IP: [<ffffffff810c099f>] __lock_acquire+0xd3/0xf91 PGD d3c34067 PUD d3e18067 PMD 0 Oops: 0000 [#1] SMP CPU: 2 PID: 853 Comm: tc Not tainted 4.6.0+ #87 Hardware name: Bochs Bochs, BIOS Bochs 01/01/2011 task: ffff8800d3e28040 ti: ffff8800d3f6c000 task.ti: ffff8800d3f6c000 RIP: 0010:[<ffffffff810c099f>] [<ffffffff810c099f>] __lock_acquire+0xd3/0xf91 RSP: 0000:ffff88011b203c80 EFLAGS: 00010002 RAX: 0000000000000046 RBX: 0000000000000000 RCX: 0000000000000000 RDX: 0000000000000000 RSI: 0000000000000000 RDI: 0000000000000028 RBP: ffff88011b203d40 R08: 0000000000000001 R09: 0000000000000000 R10: ffff88011b203d58 R11: ffff88011b208000 R12: 0000000000000001 R13: ffff8800d3e28040 R14: 0000000000000028 R15: 0000000000000000 FS: 0000000000000000(0000) GS:ffff88011b200000(0000) knlGS:0000000000000000 CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 CR2: 0000000000000028 CR3: 00000000d4be1000 CR4: 00000000000006e0 Stack: ffff8800d3e289c0 0000000000000046 000000001b203d60 ffffffff00000000 0000000000000000 ffff880000000000 0000000000000000 ffffffff00000000 ffffffff8187142c ffff88011b203ce8 ffff88011b203ce8 ffffffff8101dbfc Call Trace: <IRQ> [<ffffffff8187142c>] ? __tcf_hash_release+0x77/0xd1 [<ffffffff8101dbfc>] ? native_sched_clock+0x1a/0x35 [<ffffffff8101dbfc>] ? native_sched_clock+0x1a/0x35 [<ffffffff810a9604>] ? sched_clock_local+0x11/0x78 [<ffffffff810bf6a1>] ? mark_lock+0x24/0x201 [<ffffffff810c1dbd>] lock_acquire+0x120/0x1b4 [<ffffffff810c1dbd>] ? lock_acquire+0x120/0x1b4 [<ffffffff8187142c>] ? __tcf_hash_release+0x77/0xd1 [<ffffffff81aad89f>] _raw_spin_lock_bh+0x3c/0x72 [<ffffffff8187142c>] ? __tcf_hash_release+0x77/0xd1 [<ffffffff8187142c>] __tcf_hash_release+0x77/0xd1 [<ffffffff81871a27>] tcf_action_destroy+0x49/0x7c [<ffffffff81870b1c>] tcf_exts_destroy+0x20/0x2d [<ffffffff8189273b>] u32_destroy_key+0x1b/0x4d [<ffffffff81892788>] u32_delete_key_freepf_rcu+0x1b/0x1d [<ffffffff810de3b8>] rcu_process_callbacks+0x610/0x82e [<ffffffff8189276d>] ? u32_destroy_key+0x4d/0x4d [<ffffffff81ab0bc1>] __do_softirq+0x191/0x3f4 Fixes: ddf97ccd ("net_sched: add network namespace support for tc actions") Cc: Jamal Hadi Salim <jhs@mojatatu.com> Signed-off-by:

We properly scan the flow list to count number of packets, but John passed 0 to gnet_stats_copy_queue() so we report a zero value to user space instead of the result. Fixes: 64015853 ("net: sched: restrict use of qstats qlen") Signed-off-by:

Jakub Kicinski says: ==================== cls_u32 hardware offload fixes This set fixes two small issues with error codes I noticed in cls_u32. Second patch could be viewed as user space API change but that portion of API is not part of any release, yet. Compile tested only. ==================== Signed-off-by: -
