Kernel Patches (proc & dmesg restriction)
I updated two kernel patches to the Linux kernel.
- linux-2.6.18-proc_restrictions.patch (patch, 12 KB) which basically restricts non-root users from viewing all processes (plus an option for some additional /proc restrictions). It is possible to define a GID which is not affected by the restrictions.
- linux-2.6.18-dmesg_restriction.patch (patch, 1 KB) which restricts non-root users from viewing kernel log buffer messages.
Both patches are based on grsecurity – so credits go to Brad Spengler.
