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

One missing piece when I added pledge(2) to dhcpd(8) was in the code path when it's invoked with either -A/-C/-L, which at the time I left alone due to some forbidden ioctls by pledge(2). Now we have unveil(2) and this path can be further restricted by using it instead of chroot(2) since this "sandbox" (not sure why people call sandbox to about everything these days) can be escaped with *at(2) calls. Since no filesystem access is needed here then we can disable its access by calling unveil("/", "") unveil(NULL, NULL). added /* no filesystem visibility */ as per suggestion by and OK deraadt@

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.

I noticed the "pf table handler" process not going away on dhcpd restart, looked at the error handling here, and.... oh my. If opening /dev/pf on startup fails, don't just warn and move on, but bail. If chroot (or the chdir after) fail, don't just warn and move on, bail. If dropping privileges fails, the last thing we want to do is to just move on with root privs, having warned or not. If the pipe to the parent process is closed, that almost certainly means that the parent process went away, and it absolutely certainly means that the table handler process has no meaningful reason to exist any more, thus bail. ok florian ccardenas krw

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)

This diff makes dhcpd able to manipulate pf tables on certain lease events. dhcpd is now able to place abandoned addresses into a table (to offer some protection against machines camping on an address) and remove them from the table if they are properly leased. When dhcpd assigns an IP to a new hardware address, it can remove that address from a table. This is for use with the overload table in pf; newly arrived machines will not be punished for the actions of a machine that went away. beck@ and krw@ liked previous versions of this, henning@ final ok
