Subject: [PATCH v1 net 00/15] sysctl: Fix data-races around net.core.XXX (Round 1)
Date: Mon, 15 Aug 2022 22:23:32 -0700 [thread overview]
Message-ID: <20220816052347.70042-1-kuniyu@amazon.com> (raw)
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.
