| | | | | | | | | | | | | | | | | | thing it was still used for was to set the "global default" password hash. Since the stock auth.conf contained nothing but comments, the global default was actually the first algorithm in crypt(3)'s list, which happens to be DES; I take the fact that nobody noticed as proof that it was not used outside of crypt(3). The only other use in our tree was in the Kerberos support code in in tinyware's passwd(1). I removed that code in an earlier commit; it would not have compiled anyway, as it only supported Kerberos IV. The auth_getval() function is now a stub that always returns NULL, which has the same effect as a functional auth_getval() with an empty auth.conf. MFC after: 3 weeks

| | | | | | | | | | | | | | | | | | | | when the child process execs daemon's target program thanks to flock(2) semantics.

| | | | | | | | | | | | | | | | | | | | | | | file and processes information retrieval from the running kernel via sysctl in the form of new library, libprocstat. The library also supports KVM backend for analyzing memory crash dumps. Both procstat(1) and fstat(1) utilities have been modified to take advantage of the library (as the bonus point the fstat(1) utility no longer need superuser privileges to operate), and the procstat(1) utility is now able to display information from memory dumps as well. The newly introduced fuser(1) utility also uses this library and able to operate via sysctl and kvm backends. The library is by no means complete (e.g. KVM backend is missing vnode name resolution routines, and there're no manpages for the library itself) so I plan to improve it further. I'm commiting it so it will get wider exposure and review. We won't be able to MFC this work as it relies on changes in HEAD, which was introduced some time ago, that break kernel ABI. OTOH we may be able to merge the library with KVM backend if we really need it there. Discussed with: rwatson
