* When system calls indicate an error they return -1, not some arbitraryderaadt2019-06-281-2/+2
| | | | | | 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,mestre2018-10-261-3/+17
| | | | | | | | | | | | | | | | 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@
* The call to setegid(2) was replaced with setresgid(2) a while ago.tb2017-11-211-2/+2

| | | | | *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 pledgederaadt2015-10-131-9/+16
| | | | | | | | "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
* kvm_mkdb & dev_mkdb are quite similar. pledge "stdio rpath wpath cpath"deraadt2015-10-121-1/+4

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)

* Only exit in nlist.c due to a memory error, otherwise just return. A return value of 1 indicates an incorrect executable type, a return value of -1 indicates some other problem. This gives us better fallback from /dev/ksyms to /bsd.millert1999-03-241-17/+18

| | | | | | | | | | | o testdb() needs to take as an arg the name of the kernel so it can do the version test correctly. o add undocumented verbose flag to tell when we are rebuilding the .db file o DO_* -> _NLIST_DO_*, this prevented kvm_mkdb from doing anything at all. o preserve a few error messages so you get error output when none of the exec types match the target. o check malloc return values o get_kerntext should not subtract the sizeof(struct exec) from kernel_text
