In order to get realtime capabilities, jackd can be run with a suid wrapper (jackstart), instead of being run as root, if the following patch is applied to the kernel:
--- capability.h.old 2003-11-11 19:57:49.000000000 -0700 +++ capability.h 2003-11-11 19:56:55.000000000 -0700 @@ -303,8 +303,8 @@ #define CAP_EMPTY_SET to_cap_t(0) #define CAP_FULL_SET to_cap_t(~0) -#define CAP_INIT_EFF_SET to_cap_t(~0&~CAP_TO_MASK(CAP_SETPCAP)) -#define CAP_INIT_INH_SET to_cap_t(0) +#define CAP_INIT_EFF_SET to_cap_t(~0) +#define CAP_INIT_INH_SET to_cap_t(~0) #define CAP_TO_MASK(x) (1 << (x)) #define cap_raise(c, flag) (cap_t(c) |= CAP_TO_MASK(flag)) Would it be inappropriate to create a kernel-patch package for this patch? What should I call it?
