* Consensus between bde and pjd seemed to be that if the function namesGuy Helmer2012-01-261-8/+8

| | | | | | | | | for pidfh in libutil.h in its place. This allows us to hide the contents of the pidfh structure, and also allowed removal of the "#ifdef _SYS_PARAM_H" guard from around the pidfile_* function prototypes. Suggested by pjd.

* Modify pw_copy:Baptiste Daroussin2011-12-153-1/+1198
| | | | | | | | | | | | | - if pw is NULL and oldpw is not NULL then the oldpw is deleted - if pw->pw_name != oldpw->pw_name but pw->pw_uid == oldpw->pw_uid then it renames the user add new gr_* functions so now gr_util API is similar to pw_util API, this allow to manipulate groups in a safe way.

* - Commit work from libprocstat project. These patches add support for runtimeStanislav Sedov2011-05-121-0/+5
| | | | | | | | | | | | | | | | | | | | | | | 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

| | | | | | | for the SGI Altix 350 to FreeBSD/ia64. The hardware used for porting is a two-module system, consisting of a base compute module and a CPU expansion module. SGI's NUMAFlex architecture can be an excellent platform to test CPU affinity and NUMA-aware features in FreeBSD.
* Remove login(3), logout(3) and logwtmp(3) from libutil.Ed Schouten2010-01-131-4/+0
| | | | | | | | | | These functions only apply to utmp(5). They cannot be kept intact when moving towards utmpx. The login(3) function would break, because its argument is an utmp structure. The logout(3) and logwtmp(3) functions cannot be used, since they provide a functionality which partially overlaps. Increment SHLIB_MAJOR to 9 to indicate the removal.

* Revert (once again, and hopefully for the last time) to flock(2) locks.Dag-Erling Smørgrav2009-06-061-8/+5
| | | | | | The problem with fcntl(2) locks is that they are not inherited by child processes. This breaks pidfile(3), where the common idiom is to open and lock the PID file before daemonizing.
* Merge user/peter/kinfo branch as of r185547 into head.Peter Wemm2008-12-021-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This changes struct kinfo_filedesc and kinfo_vmentry such that they are same on both 32 and 64 bit platforms like i386/amd64 and won't require sysctl wrapping. Two new OIDs are assigned. The old ones are available under COMPAT_FREEBSD7 - but it isn't that simple. The superceded interface was never actually released on 7.x. The other main change is to pack the data passed to userland via the sysctl. kf_structsize and kve_structsize are reduced for the copyout. If you have a process with 100,000+ sockets open, the unpacked records require a 132MB+ copyout. With packing, it is "only" ~35MB. (Still seriously unpleasant, but not quite as devastating). A similar problem exists for the vmentry structure - have lots and lots of shared libraries and small mmaps and its copyout gets expensive too. My immediate problem is valgrind. It traditionally achieves this functionality by parsing procfs output, in a packed format. Secondly, when tracing 32 bit binaries on amd64 under valgrind, it uses a cross compiled 32 bit binary which ran directly into the differing data structures in 32 vs 64 bit mode. (valgrind uses this to track file descriptor operations and this therefore affected every single 32 bit binary) I've added two utility functions to libutil to unpack the structures into a fixed record length and to make it a little more convenient to use.

This was noticed recently with libutil was built with WARNS=6 on platform such as sparc64. Added checks to gr_dup(), gr_equal() and gr_make() to prevent segfaults when examining struct group's with the struct members pointing to NULL's. With fix of alignment issue, restore WARNS?=6.
