cred: Hide internal flag CRED_FLAG_CAPMODE 2024-12-16T14:42:29+00:00 Olivier Certner olce@FreeBSD.org 2024-07-16T16:07:40+00:00 09290c3a0c82524138973b14f393379edf733753 This flag is used in field 'cr_flags', which is never directly visible outside the kernel. That field is however exported through 'struct kinfo_proc' objects (field 'ki_cr_flags'), either from the kernel via sysctls or from libkvm, and is supposed to contain exported flags prefixed with KI_CRF_ (currently, KI_CRF_CAPABILITY_MODE and KI_CRF_GRP_OVERFLOW, this second one being a purely userland one signaling overflow of 'ki_groups'). Make sure that KI_CRF_CAPABILITY_MODE is the flag actually exported and tested by userland programs, and hide the internal CRED_FLAG_CAPMODE. As both flags are currently defined to the same value, this doesn't change the KBI, but of course does change the KPI. A code search via GitHub and Google fortunately doesn't reveal any outside uses for CRED_FLAG_CAPMODE. While here, move assignment of 'ki_uid' to a more logical place in kvm_proclist(), and definition of XU_NGROUPS as well in 'sys/ucred.h' (no functional/interface changes intended).
