So I went to test the patches and it looks like I am running into something similar to what the kbuild test robot was reporting. For my test I was going to just do a simple routing setup with an igb pf trying to route packets to a netns with a pair of VFs on two different subnets. As soon as I brought the VFs up in the namespace they crashed with the following errors: [ 270.169580] BUG: unable to handle kernel NULL pointer dereference at 0000000000000010 [ 270.177473] IP: page_frag_alloc+0xb/0x60 [ 270.181415] PGD 0 P4D 0 [ 270.183966] Oops: 0000 [#1] SMP PTI [ 270.187476] Modules linked in: igbvf tun bridge stp llc vfat fat intel_rapl sb_edac x86_pkg_temp_thermal intel_powerclamp coretemp kvm_intel kvm irqbypass crct10dif_pclmul nfsd crc32_pclmul ghash_clmulni_intel ipmi_ssif iTCO_wdt pcbc mei_me ipmi_si iTCO_vendor_support aesni_intel crypto_simd glue_helper mei cryptd mxm_wmi wmi ioatdma ipmi_devintf i2c_i801 sg pcspkr shpchp lpc_ich mfd_core ipmi_msghandler acpi_power_meter acpi_pad auth_rpcgss nfs_acl lockd grace sunrpc binfmt_misc xfs libcrc32c sr_mod cdrom sd_mod ast drm_kms_helper syscopyarea sysfillrect sysimgblt fb_sys_fops igb ttm ixgbe i40e drm ahci mdio libahci ptp crc32c_intel libata pps_core i2c_algo_bit dca i2c_core dm_mirror dm_region_hash dm_log dm_mod dax [ 270.251286] CPU: 1 PID: 3638 Comm: ifconfig Not tainted 4.16.0-rc4+ #66 [ 270.257937] Hardware name: Supermicro X10DRH/X10DRH-i, BIOS 2.0a 06/30/2016 [ 270.264934] RIP: 0010:page_frag_alloc+0xb/0x60 [ 270.269402] RSP: 0018:ffffc900093bbb28 EFLAGS: 00010086 [ 270.274653] RAX: 0000000000000202 RBX: 0000000000000780 RCX: 0000000000000000 [ 270.281820] RDX: 0000000001080020 RSI: 0000000000000780 RDI: ffff88085f2610f0 [ 270.290557] RBP: ffff88085f2610f0 R08: 0000000001080020 R09: 000000000000030f [ 270.299196] R10: 0000000000000001 R11: 0000000000000018 R12: 0000000000000780 [ 270.307828] R13: 0000000000000202 R14: 0000000000000000 R15: ffff88084e9de880 [ 270.316461] FS: 00007f135724a740(0000) GS:ffff88085f240000(0000) knlGS:0000000000000000 [ 270.326034] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 [ 270.333226] CR2: 0000000000000010 CR3: 0000000852612001 CR4: 00000000003606e0 [ 270.341817] DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000 [ 270.350393] DR3: 0000000000000000 DR6: 00000000fffe0ff0 DR7: 0000000000000400 [ 270.358974] Call Trace: [ 270.362869] __netdev_alloc_skb+0x9b/0x100 [ 270.368420] igbvf_alloc_rx_buffers+0x23a/0x3d0 [igbvf] [ 270.375097] igbvf_open+0x63/0x130 [igbvf] [ 270.380627] __dev_open+0xcb/0x150 [ 270.385461] __dev_change_flags+0x1a4/0x1f0 [ 270.391067] ?
