perf spe-c2c record失败的问题
by haoxin 15 Dec '21

15 Dec '21

您好，我采用最细的openEuler-1.0测试perf spe-c2c的功能，但是发现/sys/devices下没有arm_spe_0这个目录执行perf spe-c2c record时显示： event syntax error: 'arm_spe_0/ts_enable=1,pct_enable=1,pa_enable=1,load_filter=1,jitter=1,store_filter=1,min_latency=0/' \___ Cannot find PMU `arm_spe_0'. Missing kernel support? 想问下您这是为什么？需要哪里开启spe功能吗？

[PATCH kernel-4.19 1/2] netfilter: add and use nf_hook_slow_list()
by Yang Yingliang 30 Jan '21

30 Jan '21

From: Florian Westphal <fw(a)strlen.de> mainline inclusion from mainline-v5.5-rc1 commit ca58fbe06c54795f00db79e447f94c2028d30124 category: bugfix bugzilla: NA CVE: CVE-2021-20177 -------------------------------- At this time, NF_HOOK_LIST() macro will iterate the list and then calls nf_hook() for each individual skb. This makes it so the entire list is passed into the netfilter core. The advantage is that we only need to fetch the rule blob once per list instead of per-skb. NF_HOOK_LIST now only works for ipv4 and ipv6, as those are the only callers. v2: use skb_list_del_init() instead of list_del (Edward Cree) Signed-off-by: Florian Westphal <fw(a)strlen.de> Acked-by: Edward Cree <ecree(a)solarflare.com> Signed-off-by: Pablo Neira Ayuso <pablo(a)netfilter.org> Conflicts: include/linux/netfilter.h net/netfilter/core.c [yyl: adjust context] Signed-off-by: Yang Yingliang <yangyingliang(a)huawei.com> Reviewed-by: Yue Haibing <yuehaibing(a)huawei.com> Reviewed-by: Jason Yan <yanaijie(a)huawei.com> Signed-off-by: Yang Yingliang <yangyingliang(a)huawei.com> --- include/linux/netfilter.h | 41 +++++++++++++++++++++++++++++---------- net/netfilter/core.c | 20 +++++++++++++++++++ 2 files changed, 51 insertions(+), 10 deletions(-) diff --git a/include/linux/netfilter.h b/include/linux/netfilter.h index 9460a5635c90..8bf57abee9e4 100644 --- a/include/linux/netfilter.h +++ b/include/linux/netfilter.h @@ -183,6 +183,8 @@ extern struct static_key nf_hooks_needed[NFPROTO_NUMPROTO][NF_MAX_HOOKS]; int nf_hook_slow(struct sk_buff *skb, struct nf_hook_state *state, const struct nf_hook_entries *e, unsigned int i); +void nf_hook_slow_list(struct list_head *head, struct nf_hook_state *state, + const struct nf_hook_entries *e); /** * nf_hook - call a netfilter hook * @@ -295,17 +297,36 @@ NF_HOOK_LIST(uint8_t pf, unsigned int hook, struct net *net, struct sock *sk, struct list_head *head, struct net_device *in, struct net_device *out, int (*okfn)(struct net *, struct sock *, struct sk_buff *)) { - struct sk_buff *skb, *next; - struct list_head sublist; - - INIT_LIST_HEAD(&sublist); - list_for_each_entry_safe(skb, next, head, list) { - skb_list_del_init(skb); - if (nf_hook(pf, hook, net, sk, skb, in, out, okfn) == 1) - list_add_tail(&skb->list, &sublist); + struct nf_hook_entries *hook_head = NULL; + +#ifdef CONFIG_JUMP_LABEL + if (__builtin_constant_p(pf) && + __builtin_constant_p(hook) && + !static_key_false(&nf_hooks_needed[pf][hook])) + return; +#endif + + rcu_read_lock(); + switch (pf) { + case NFPROTO_IPV4: + hook_head = rcu_dereference(net->nf.hooks_ipv4[hook]); + break; + case NFPROTO_IPV6: + hook_head = rcu_dereference(net->nf.hooks_ipv6[hook]); + break; + default: + WARN_ON_ONCE(1); + break; } - /* Put passed packets back on main list */ - list_splice(&sublist, head); + + if (hook_head) { + struct nf_hook_state state; + + nf_hook_state_init(&state, hook, pf, in, out, sk, net, okfn); + + nf_hook_slow_list(head, &state, hook_head); + } + rcu_read_unlock(); } /* Call setsockopt() */ diff --git a/net/netfilter/core.c b/net/netfilter/core.c index 93aaec3a54ec..3f0bdc728f89 100644 --- a/net/netfilter/core.c +++ b/net/netfilter/core.c @@ -536,6 +536,26 @@ int nf_hook_slow(struct sk_buff *skb, struct nf_hook_state *state, EXPORT_SYMBOL(nf_hook_slow); +void nf_hook_slow_list(struct list_head *head, struct nf_hook_state *state, + const struct nf_hook_entries *e) +{ + struct sk_buff *skb, *next; + struct list_head sublist; + int ret; + + INIT_LIST_HEAD(&sublist); + + list_for_each_entry_safe(skb, next, head, list) { + skb_list_del_init(skb); + ret = nf_hook_slow(skb, state, e, 0); + if (ret == 1) + list_add_tail(&skb->list, &sublist); + } + /* Put passed packets back on main list */ + list_splice(&sublist, head); +} +EXPORT_SYMBOL(nf_hook_slow_list); + int skb_make_writable(struct sk_buff *skb, unsigned int writable_len) { if (writable_len > skb->len) -- 2.25.1

[FAQ] Introduce a JVMTI plug-in fix to openEuler release
by Erik Yuan 28 Jan '21

28 Jan '21

Hi, In Linux 5.8, Nick submitted a patch-set to fix some Errors in symbol search when you try to profile JIT compiled application in OpenJDK with perf. The patchset is: 1e4bd2ae4564 perf jit: Fix inaccurate DWARF line table 7d7e503cac31 perf jvmti: Remove redundant jitdump line table entries 0bdf31811be0 perf jvmti: Fix demangling Java symbols 525c821de0a6 perf tests: Add test for the java demangler 959f8ed4c1a8 perf jvmti: Do not report error when missing debug information 953e92402a52 perf jvmti: Fix jitdump for methods without debug info Because making perf work is very useful for performance analysis on JITed Java application, I'd like to support this patchset in openEuler release. The coming 21.03 should be a first target as that release is upgraded with 5.8+ kernel. Probably we can backport this patchset to 20.03 LTS if needed. To introduce the fix to 21.03, the kernel.spec should be changed with some lines to generate the JVMTI shared library. There are some things I am not sure: 1. kernel.spec is in src-openeuler project, do I submit the change by PR or by sending patch directly to the mailing list? 2. Is there rolling release of openEuler like Tumbleweed? Then we can run some tests with the daily ISO before the stable 21.03 And one more question, has version 21.03 created a build project in openEuler OBS?? Is it this one? https://build.openeuler.org/package/show/openEuler:Mainline/kernel Thanks, Erik

Maybe we can put the check into set_vm_checknode(). What do you think? mm/mmap.c if (flags & MAP_CHECKNODE) set_vm_checknode(&vm_flags, flags); Thanks， Bixuan Cui
