Date: Mon, 15 Aug 2022 22:23:32 -0700 From: Kuniyuki Iwashima <kuniyu@...zon.com> To: "David S. Miller" <davem@...emloft.net>, Eric Dumazet <edumazet@...gle.com>, Jakub Kicinski <kuba@...nel.org>, Paolo Abeni <pabeni@...hat.com> CC: Kuniyuki Iwashima <kuniyu@...zon.com>, Kuniyuki Iwashima <kuni1840@...il.com>, <netdev@...r.kernel.org>, <linux-kernel@...r.kernel.org> Subject: [PATCH v1 net 00/15] sysctl: Fix data-races around net.core.XXX (Round 1) This series fixes data-races around 22 knobs in net_core_table. These knobs are skipped: - netdev_rss_key: Written only once by net_get_random_once() and read-only knob - rps_sock_flow_entries: Protected with sock_flow_mutex - flow_limit_cpu_bitmap: Protected with flow_limit_update_mutex - flow_limit_table_len: Protected with flow_limit_update_mutex - default_qdisc: Protected with qdisc_mod_lock - warnings: Unused Note 9th patch fixes net.core.message_cost and net.core.message_burst, and lib/ratelimit.c does not have an explicit maintainer. The next round is the final round for net.core.XXX and starts from netdev_budget_usecs. Kuniyuki Iwashima (15): net: Fix data-races around sysctl_[rw]mem_(max|default). net: Fix data-races around weight_p and dev_weight_[rt]x_bias. net: Fix data-races around netdev_max_backlog. bpf: Fix data-races around bpf_jit_enable. bpf: Fix data-races around bpf_jit_harden. bpf: Fix data-races around bpf_jit_kallsyms. bpf: Fix a data-race around bpf_jit_limit. net: Fix data-races around netdev_tstamp_prequeue. ratelimit: Fix data-races in ___ratelimit(). net: Fix data-races around sysctl_optmem_max. net: Fix a data-race around sysctl_tstamp_allow_data. net: Fix a data-race around sysctl_net_busy_poll. net: Fix a data-race around sysctl_net_busy_read. net: Fix a data-race around netdev_budget. net: Fix data-races around sysctl_max_skb_frags.
