From 49accde7bd915944d99c947dca0cf26ae0f24165 Mon Sep 17 00:00:00 2001 From: Djalal Harouni Date: Sun, 25 Sep 2016 11:30:11 +0200 Subject: core:sandbox: add more /proc/* entries to ProtectKernelTunables= Make ALSA entries, latency interface, mtrr, apm/acpi, suspend interface, filesystems configuration and IRQ tuning readonly. Most of these interfaces now days should be in /sys but they are still available through /proc, so just protect them. This patch does not touch /proc/net/... --- src/core/namespace.c | 11 +++++++++++ 1 file changed, 11 insertions(+) (limited to 'src') diff --git a/src/core/namespace.c b/src/core/namespace.c index 8aa8b83c88..3234fab4bc 100644 --- a/src/core/namespace.c +++ b/src/core/namespace.c @@ -74,7 +74,18 @@ typedef struct TargetMount { static const TargetMount protect_kernel_tunables_table[] = { { "/proc/sys", READONLY, false }, { "/proc/sysrq-trigger", READONLY, true }, + { "/proc/latency_stats", READONLY, true }, + { "/proc/mtrr", READONLY, true }, + { "/proc/apm", READONLY, true }, + { "/proc/acpi", READONLY, true }, + { "/proc/timer_stats", READONLY, true }, + { "/proc/asound", READONLY, true }, + { "/proc/bus", READONLY, true }, + { "/proc/fs", READONLY, true }, + { "/proc/irq", READONLY, true }, { "/sys", READONLY, false }, + { "/sys/kernel/debug", READONLY, true }, + { "/sys/kernel/tracing", READONLY, true }, { "/sys/fs/cgroup", READWRITE, false }, /* READONLY is set by ProtectControlGroups= option */ }; -- cgit v1.2.3-54-g00ecf
