For open/openat, if the flags parameter does not contain O_CREAT, the 3rd (variadic) mode_t parameter is irrelevant. Many developers in the past have passed mode_t (0, 044, 0644, or such), which might lead future people to copy this broken idiom, and perhaps even believe this parameter has some meaning or implication or application. Delete them all. This comes out of a conversation where tb@ noticed that a strange (but intentional) pledge behaviour is to always knock-out high-bits from mode_t on a number of system calls as a safety factor, and his bewilderment that this appeared to be happening against valid modes (at least visually), but no sorry, they are all irrelevant junk. They could all be 0xdeafbeef. ok millert

When system calls indicate an error they return -1, not some arbitrary value < 0. errno is only updated in this case. Change all (most?) callers of syscalls to follow this better, and let's see if this strictness helps us in the future.

If we pass `file' via args then we need to unveil(2) it with read permission, otherwise if omitted we need to unveil(2) both _PATH_UNIX and _PATH_KSYMS with same permissions. Unconditionally we need to also unveil(2) dbdir, which by default is _PATH_VARDB but can be changed via args (-o directory), with read/write/create permissions. There are a couple of temp files that will be created but it's inside dbdir so there's no need to unveil(2) them individually. Since we already call pledge(2) before, twice, we need to add "unveil" promise to both of them, and finally call pledge(2) once again with the needed promises except "unveil". OK millert@

semarie points out i am already forgetting the rules are very tight around *chown, even "proc fattr" won't let you do such a job. remove early pledge(), only leave call after fchown, before when symbol table work gets done.

oops, a chown appears late on the code. to satisfy this pledge "stdio rpath wpath cpath getpw fattr proc" early on; "proc fattr" allows doing work with other uids on the file. after opening the db, do the chown (replace with fchown since we know fd) and then pledge "stdio rpath"; "rpath" due to tmpfile rename() at the end. mistake spotted by mpi

Replace <sys/param.h> with <limits.h> and other less dirty headers where possible. Annotate <sys/param.h> lines with their current reasons. Switch to PATH_MAX, NGROUPS_MAX, HOST_NAME_MAX+1, LOGIN_NAME_MAX, etc. Change MIN() and MAX() to local definitions of MINIMUM() and MAXIMUM() where sensible to avoid pulling in the pollution. These are the files confirmed through binary verification. ok guenther, millert, doug (helped with the verification protocol)
