In libc, there used to be.
A quick and dirty patch, unsuitable for mainline is this:
Newer libcs don't define the JB_* jmp_buf access mac
Thanks for this. There is still upstream build breakage, on latest
linux-2.6.git (x86_64, FC5, attached config):
CC arch/um/os-Linux/sys-x86_64/registers.o
arch/um/os-Linux/sys-x86_64/registers.c: In function ‘get_thread_regs’:
arch/um/os-Linux/sys-x86_64/registers.c:85: error: ‘JB_PC’
I was trying to limit some unecessary capabilities in a UML instance
with /proc/sys/kernel/cap-bound, but it turned out not to take.
The source of the problem (or at least something a bit of the way up
the garden path of the problem) is at security/commoncap.c:140 at the
top of cap_bprm_apply_cred
