[01:35] <pocoyo> SJX: 知道吗？
[01:36] <SJX> 不清楚啊，昨天刚用上irc...
[02:09] <ooOO_OOoo> iMadper: 壕早
[02:12] <iMadper> ooOO_OOoo: 早.
[02:12] <iMadper> ooOO_OOoo: 王老板日子这么滋润?
[02:12] <iMadper> ooOO_OOoo: 我还想请教几个ltp的问题呢
[02:12] <ooOO_OOoo> iMadper: 王老板现在niu了呢
[02:13] <iMadper> huntxu: 我
[02:13] <iMadper> huntxu: 修好
[02:13] <iMadper> huntxu: 输入法
[02:13] <iMadper> huntxu: 了
[02:13] <iMadper> ooOO_OOoo: 肯定的啊
[02:13] <iMadper> ooOO_OOoo: 王老板离senior多远?
[02:13] <iMadper> ooOO_OOoo: 一年?
[02:13] <ooOO_OOoo> ooOO_OOoo: 他说重装了系统，刚把 irc server 发给他了
[02:13] <ooOO_OOoo> iMadper: 估计也快了
[02:15] <iMadper> ooOO_OOoo: 昂.
[02:21] <ooOO_OOoo> iMadper: ltp啥问题，王老板还没上线。。 你急的话我问问他
[02:25] <wangli> iMadper
[02:25] <ooOO_OOoo> wangli: 王老板早
[02:25] <wangli> 谢老板早
[02:29] <wangli> iMadper,
[02:30] <iMadper> wangli: 早
[02:30] <iMadper> wangli: 问一下, 现在systemd情况下, 跑ltp会有很多失败啊
[02:30] <iMadper> wangli: cgroup相关的
[02:30] <wangli> 啥失败
[02:30] <iMadper> wangli: 因为systemd一上来就会按照他需要的拓扑mount很多cgroup的实例
[02:31] <wangli> iMadper, 贴出来看看
[02:31] <iMadper> wangli: 然后ltp的case假设是干净的系统
[02:31] <iMadper> wangli: 好的
[02:33] <iMadper> wangli: https://pastebin.com/B0Znwcu2
[02:34] <MangHuoEr> 对啊
[02:34] <MangHuoEr> 高级了
[02:34] <wangli> iMadper, checking
[02:41] <wangli> iMadper, hi, which ltp-version did you run? and what's the kernel-version/arch/platform?
[02:42] <iMadper> wangli: LTP Version: 20170516   kernel: modified 4.11 aarch64
[02:42] <wangli> iMadper, it seems not a systemd problem, i guess it is related to cgroup or kernel bug, but still need do some more research
[02:43] <iMadper> wangli: So it's not a known bug?
[02:43] <wangli>  iMadper sorry for input English, my workstation always hung with input Chinese:(
[02:43] <iMadper> MangHuoEr: ^^
[02:44] <iMadper> wangli: I was expecting it's a conflict between ltp and systemd. loool
[02:44] <wangli> iMadper, not sure, and can you run the latest ltp-20170929 version?
[02:45] <iMadper> wangli: any modifications against the cgroup cases?
[02:45] <wangli> memcg_stat_test 6 TFAIL: hierarchical_memory_limit is 65536, 131072 expected
[02:46] <iMadper> wangli: Yes, because the parent node has a limit of 65536...
[02:47] <wangli> iMadper, so you guess the limit set to 65536 in systemd?
[02:47] <iMadper> wangli: *nod*
[02:48] <wangli> iMadper, sounds reasonable, but we need some more debugging
[02:48] <iMadper> wangli: so you never met that issue?
[02:50] <wangli> iMadper, i didn't run the cgroup cases before, let me try it now
[02:50] <MangHuoEr> cat /sys/fs/cgroup/memory/memory.use_hierarchy  ?
[02:51] <iMadper> wangli: okay. Shouldn't memcg belong to ktd-team?
[02:52] <wangli> iMadper, it's not my working area, but i can do it for you
[02:52] <wangli> iMadper, just wait..
[02:54] <iMadper> wangli: thanks tons.
[02:59] <kevin125> 怎么他突然e文了
[02:59] <MangHuoEr> 是的
[02:59] <wangli> iMadper, can you perform 'cat /sys/fs/cgroup/memory/memory.use_hierarchy' as MangHuoEr mentioned above?
[03:00] <iMadper> wangli: 1
[03:01] <wangli> iMadper, ok, it's not the hierarchy problem
[03:01] <iMadper> wangli: what's the value in your side?
[03:01] <wangli> i just noticed that ltp disable it in the cgroup case
[03:01] <wangli> echo 0 > memory.use_hierarchy
[03:02] <wangli> so it's not related to systemd i think
[03:03] <wangli> iMadper, the page_size on your system is?
[03:04] <iMadper> wangli: however if it has a sub-node, we can't change the value.
[03:04] <iMadper> wangli: and by default, systemd creates sub-nodes.
[03:05] <wangli> [03:05] <wangli> testcase_6()
[03:05] <wangli> {
[03:05] <wangli> 	echo 0 > memory.use_hierarchy
[03:05] <wangli> 	mkdir subgroup
[03:05] <wangli> 	echo $PAGESIZE > memory.limit_in_bytes
[03:05] <wangli> 	echo $((PAGESIZE*2)) > subgroup/memory.limit_in_bytes
[03:05] <ubrl> wangli:. .., 别刷屏，超过6行 大段文字 请贴至paste.ubuntu.com +q 23s
[03:05] <wangli> 	cd subgroup
[03:05] <wangli> 	check_mem_stat "hierarchical_memory_limit" $((PAGESIZE*2))
[03:05] <wangli> 	cd ..
[03:05] <wangli> 	rmdir subgroup
[03:05] <wangli> }
[03:06] <wangli> memcg_stat_test 6 TPASS: hierarchical_memory_limit is 8192 as expected
[03:06] <iMadper>  	echo 0 > memory.use_hierarchy   <--- this line fails.
[03:06] <wangli> iMadper, I get pass on my x86_64 box
[03:06] <wangli> iMadper, really?
[03:06] <iMadper> do you have a sub-node before executing the test case?
[03:07] <iMadper> try to create one before executing it.
[03:07] <wangli> i didn't, i just run ltp by default
[03:07] <wangli> sure
[03:10]  * iMadper brb
[03:11] <wangli> # echo 0 > /dev/memcg/wangli/memory.use_hierarchy
[03:11] <wangli> # cat /dev/memcg/wangli/memory.use_hierarchy
[03:11] <wangli> 0
[03:12] <wangli> iMadper, ^
[03:12] <iMadper> wangli: so you can still change parent's memory.use_hierarchy?
[03:13] <iMadper> wangli: the child node could always be modified. However, in the meanwhile, parent's can't
[03:15] <wangli> iMadper, hmm, what kind of situation you hit? I didn't fully understand you mean
[03:16] <iMadper> wangli: okay, you have a sub-node "wangli" which located in /dev/memcg/wangli. could you still echo 0/1 > /dev/memcg/memory.use_hierarchy ?
[03:17] <iMadper> wangli: What I'm trying to express is: Given a memcg node A. Once A has a child node, The _A_'s use_hierarchy can't be changed.
[03:17] <wangli> iMadper, understand
[03:18] <wangli> iMadper, i can't modify the parent's too
[03:20] <iMadper> wangli: Okay. So by default there is no sub-node inside memcg on rhel7?
[03:20] <wangli> iMadper, seems yes!
[03:21] <iMadper> wangli: I see.
[03:21] <wangli> iMadper, if so, we probably need to modify the ltp-case to cover your system
[03:22] <iMadper> wangli: yeah, for ubuntu...
[03:23] <iMadper> wangli: it seems the default behavior of ubuntu systemd leads the issue.
[03:24] <wangli> iMadper, can you show me the cgroup dir in your system?
[03:26] <MangHuoEr> wangli: iMadper http://pastebin.ubuntu.com/25855776/
