2019-07-30drm/i915/gvt: Adding ppgtt to GVT GEM context after shadow pdps settled.Colin Xu
Windows guest can't run after force-TDR with host log: ... gvt: vgpu 1: workload shadow ppgtt isn't ready gvt: vgpu 1: fail to dispatch workload, skip ... The error is raised by set_context_ppgtt_from_shadow(), when it checks and found the shadow_mm isn't marked as shadowed. In work thread before each submission, a shadow_mm is set to shadowed in: shadow_ppgtt_mm() <-intel_vgpu_pin_mm() <-prepare_workload() <-dispatch_workload() <-workload_thread() However checking whether or not shadow_mm is shadowed is prior to it: set_context_ppgtt_from_shadow() <-dispatch_workload() <-workload_thread() In normal case, create workload will check the existence of shadow_mm, if not it will create a new one and marked as shadowed. If already exist it will reuse the old one. Since shadow_mm is reused, checking of shadowed in set_context_ppgtt_from_shadow() actually always see the state set in creation, but not the state set in intel_vgpu_pin_mm(). When force-TDR, all engines are reset, since it's not dmlr level, all ppgtt_mm are invalidated but not destroyed. Invalidation will mark all reused shadow_mm as not shadowed but still keeps in ppgtt_mm_list_head. If workload submission phase those shadow_mm are reused with shadowed not set, then set_context_ppgtt_from_shadow() will report error. Pin for context after shadow_mm pinned and shadow pdps settled. v2: Move set_context_ppgtt_from_shadow() after prepare_workload().

2019-07-29mlxsw: spectrum_ptp: Increase parsing depth when PTP is enabledPetr Machata
Spectrum systems have a configurable limit on how far into the packet they parse. By default, the limit is 96 bytes. An IPv6 PTP packet is layered as Ethernet/IPv6/UDP (14+40+8 bytes), and sequence ID of a PTP event is only available 32 bytes into payload, for a total of 94 bytes. When an additional 802.1q header is present as well (such as when ptp4l is running on a VLAN port), the parsing limit is exceeded. Such packets are not recognized as PTP, and are not timestamped. Therefore generalize the current VXLAN-specific parsing depth setting to allow reference-counted requests from other modules as well. Keep it in the VXLAN module, because the MPRS register also configures UDP destination port number used for VXLAN, and is thus closely tied to the VXLAN code anyway. Then invoke the new interfaces from both VXLAN (in obvious places), as well as from PTP code, when the (global) timestamping configuration changes from disabled to enabled or vice versa.

Shijie Luo reported that when stress-testing ipset with multiple concurrent create, rename, flush, list, destroy commands, it can result ipset <version>: Broken LIST kernel message: missing DATA part! error messages and broken list results. The problem was the rename operation was not properly handled with respect of listing. The patch fixes the issue.

2019-07-29netfilter: ipset: Copy the right MAC address in bitmap:ip,mac and ↵Stefano Brivio
hash:ip,mac sets In commit 8cc4ccf58379 ("ipset: Allow matching on destination MAC address for mac and ipmac sets"), ipset.git commit 1543514c46a7, I added to the KADT functions for sets matching on MAC addreses the copy of source or destination MAC address depending on the configured match. This was done correctly for hash:mac, but for hash:ip,mac and bitmap:ip,mac, copying and pasting the same code block presents an obvious problem: in these two set types, the MAC address is the second dimension, not the first one, and we are actually selecting the MAC address depending on whether the first dimension (IP address) specifies source or destination. Fix this by checking for the IPSET_DIM_TWO_SRC flag in option flags. This way, mixing source and destination matches for the two dimensions of ip,mac set types works as expected. With this setup: ip netns add A ip link add veth1 type veth peer name veth2 netns A ip addr add 192.0.2.1/24 dev veth1 ip -net A addr add 192.0.2.2/24 dev veth2 ip link set veth1 up ip -net A link set veth2 up dst=$(ip netns exec A cat /sys/class/net/veth2/address) ip netns exec A ipset create test_bitmap bitmap:ip,mac range 192.0.0.0/16 ip netns exec A ipset add test_bitmap 192.0.2.1,${dst} ip netns exec A iptables -A INPUT -m set ! --match-set test_bitmap src,dst -j DROP ip netns exec A ipset create test_hash hash:ip,mac ip netns exec A ipset add test_hash 192.0.2.1,${dst} ip netns exec A iptables -A INPUT -m set ! --match-set test_hash src,dst -j DROP ipset correctly matches a test packet: # ping -c1 192.0.2.2 >/dev/null # echo $? 0 Reported-by: Chen Yi <yiche@redhat.com> Fixes: 8cc4ccf58379 ("ipset: Allow matching on destination MAC address for mac and ipmac sets") Signed-off-by: Stefano Brivio <sbrivio@redhat.com> Signed-off-by: Jozsef Kadlecsik <kadlec@netfilter.org>

sets too In commit 8cc4ccf58379 ("ipset: Allow matching on destination MAC address for mac and ipmac sets"), ipset.git commit 1543514c46a7, I removed the KADT check that prevents matching on destination MAC addresses for hash:mac sets, but forgot to remove the same check for hash:ip,mac set.
