(CONFIG_VMSPLIT_2G=y) That sounds promising as well. I was also wondering if it would make sense to allow one to disable the snmp stats for ipv6? I don't think I have any use for those stats anyway..

We use normal (4KB) pages, unfortunately. I have a NUMA machine, with two nodes, so pcpu_get_vm_areas() allocates two zones, one for each node, with a 'known' offset between them. Then, 4KB pages are allocated to populate the zone when needed. # grep pcpu_get_vm_areas /proc/vmallocinfo 0xffffe8ffa0400000-0xffffe8ffa0600000 2097152 pcpu_get_vm_areas+0x0/0x740 vmalloc 0xffffe8ffffc00000-0xffffe8ffffe00000 2097152 pcpu_get_vm_areas+0x0/0x740 vmalloc BTW, we dont have the number of pages currently allocated in each 'vmalloc' zone, and/or node information.

Only around 520 interfaces properly set their IPs, and again there are errors about of-of-memory from 'ip', but no obvious splats in dmesg. 'top' shows 10G or so free. It will take some time to figure out what exactly is returning the ENOMEM....

At least I don't see any percpu dumps in dmesg. I vaguely remember someone posting some ipv6 address scalability patches some time back. I think they had to hack on /proc fs as well.

I'm getting all of the IP addrs set now, but having trouble with some of the default gateways (I have one routing table per interface). ./local/sbin/ip -6 route replace default via 2002:9:8::1 dev eth7#458 table 726 RTNETLINK answers: No buffer space available dmesg is full of this: [247106.294743] ipv6: Neighbour table overflow. A quick look in /proc didn't show a tunable for this, but I'll go grub through the code. As for the route/max_size, it would be nice to see some useful kernel message in dmesg when this hit. Just telling the user '-ENOMEM' is not at all sufficient to help them figure out the problem. For that matter, why is there such a limit anyway? IPv4 doesn't appear to have any such limit?

There are limits for ipv4, much bigger, you probably never noticed. /proc/sys/net/ipv4/route/gc_elasticity:8 /proc/sys/net/ipv4/route/gc_interval:60 /proc/sys/net/ipv4/route/gc_min_interval:0 /proc/sys/net/ipv4/route/gc_min_interval_ms:500 /proc/sys/net/ipv4/route/gc_thresh:131072 /proc/sys/net/ipv4/route/gc_timeout:300 /proc/sys/net/ipv4/route/max_size:2097152 <<< HERE /proc/sys/net/ipv4/route/min_adv_mss:256 /proc/sys/net/ipv4/route/min_pmtu:552 /proc/sys/net/ipv4/route/mtu_expires:600 /proc/sys/net/ipv4/route/redirect_load:2 /proc/sys/net/ipv4/route/redirect_number:9 /proc/sys/net/ipv4/route/redirect_silence:2048 I suggest followup discussion can got to netdev only, now per-cpu it not anymore the problem ? ^ permalink raw reply [flat|nested] 13+ messages in thread

Till now, the percpu usage hasn't justified allocating hugepages but it might someday, but more importantly the reason why those big chunks of address space are used is to keep the first chunk embedded in the regular linear kernel address space to avoid extra TLB pressure. On configurations where vmalloc area is a scarce resource, percpu_alloc=page can be specified to use page-mapped allocation. This will use much smaller chunks in vmalloc area at the cost of additional 4k page TLB pressure for percpu memory in the first chunk (all the static percpu variables and then some). pcpu_embed_first_chunk() contains heuristic which makes it yield to page allocator but the parameter is pretty generous (maximum distance between chunks > 75% of vmalloc area). It's there just to avoid completely crazy cases. Also, x86 setup_per_cpu_areas() chooses page allocator on 32bit NUMAs. This case didn't trigger either. We probably need to add another condition. That large machine on 32bit is bound to be flaky. To be short on virtual address space is a pretty silly and stupid thing. Anyways, any good idea on what criteria we could test?
