kernel: sysctl: Fix data races in proc_douintvec().

In the Linux kernel, the following vulnerability has been resolved: sysctl: Fix data races in procdouintvec. A sysctl variable is accessed concurrently, and there is always a chance of data-race. So, all readers and writers need some basic protection to avoid load/store-tearing. This patch change...

kernel: bpf: Fix a data-race around bpf_jit_limit.

In the Linux kernel, the following vulnerability has been resolved: bpf: Fix a data-race around bpfjitlimit. While reading bpfjitlimit, it can be changed concurrently via sysctl, WRITEONCE in doprocdoulongvecminmax. The size of bpfjitlimit is long, so we need to add a paired READONCE to avoid...
