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

Change all tame callers to namechange to pledge(2).

possible. Annotate 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)
