Hi, This is a two patch series to make the compile time default of unprivileged BPF depend on CONFIG_CPU_SPECTRE. First patch makes ARM's CONFIG_CPU_SPECTRE available for all architectures. The second patch sets CONFIG_BPF_UNPRIV_DEFAULT_OFF=y by default when CONFIG_CPU_SPECTRE=y. v2: - Generalize ARM's CONFIG_CPU_SPECTRE to be available for all architectures. - Make CONFIG_BPF_UNPRIV_DEFAULT_OFF depend on CONFIG_CPU_SPECTRE. - Updated commit message to reflect the dependency on CONFIG_CPU_SPECTRE. - Add reference to BPF spectre presentation in commit message. v1: https://lore.kernel.org/all/d37b01e70e65dced2659561ed5bc4b2ed1a50711.1635367330.git.pawan.kumar.gupta@xxxxxxxxxxxxxxx/ Pawan Gupta (2): arch/Kconfig: Make CONFIG_CPU_SPECTRE available for all architectures bpf: Make unprivileged bpf depend on CONFIG_CPU_SPECTRE arch/Kconfig | 3 +++ arch/arm/mm/Kconfig | 3 --- arch/x86/Kconfig | 1 + kernel/bpf/Kconfig | 5 +++++ 4 files changed, 9 insertions(+), 3 deletions(-) -- 2.31.1
