Incidentally, there are multiple PRs on this; Ernst seems to have charge of them. There's been some dodgy diagonsis, due to using a FreeBSD trace against a linux binary. The problem isn't relared to statfs, it's the corresponding numbered syscall under linux, which is (still) linux_sched_getscheduler. Looking at sys/posix/p1003_1b.c, there's an attempt at CAN_AFFECT that is #ifdef'ed out: #if 0 /* * This is stolen from CANSIGNAL in kern_sig: * * Can process p, with pcred pc, do "write flavor" operations to process q? */ #define CAN_AFFECT(p, pc, q) \ ((pc)->pc_ucred->cr_uid == 0 || \ (pc)->p_ruid == (q)->p_cred->p_ruid || \ (pc)->pc_ucred->cr_uid == (q)->p_cred->p_ruid || \ (pc)->p_ruid == (q)->p_ucred->cr_uid || \ (pc)->pc_ucred->cr_uid == (q)->p_ucred->cr_uid) #else #define CAN_AFFECT(p, pc, q) ((pc)->pc_ucred->cr_uid == 0) #endif and this is what kills the getscheduler calls across the board. OK, so what now? Ernst, can you pick this up? -- jan grant, ILRT, University of Bristol. http://www.ilrt.bris.ac.uk/ Tel +44(0)117 9287088 Fax +44 (0)117 9287112 http://ioctl.org/jan/ "Do what thou wilt" shall be the whole of the license.
