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.

Implement the conv=fsync feature which does an fsync(2) after the final write to output. GNU dd also has this. It is useful for write performance measurement or guaranteed writes to reliable storage. OK kn@ tedu@ deraadt@

Don't cast malloc(3) size to u_int. Large buffer sizes on 64-bit platforms cause the sum to wrap, leading read(2) to fail later. We check prior to this point that all buffer sizes are <= SSIZE_MAX. SSIZE_MAX * 2 < SIZE_MAX on all platforms, so the addition here will not overflow and cause a similar issue. Discovered by tobias@ a while back. ok deraadt millert tobias

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)

Move check for count=0 into dd's main. We want to do normal setup in this case and just don't want to actually copy any data. Fixes a problem noted by aaron@ where the time portion of the summary would be wrong and also gives us sane behavior when seek is non-zero but count is 0.
