* 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.

* Make <libutil.h> work when included by itself.Ed Schouten2009-12-021-0/+28
| | | | | | | There are several reasons why it didn't work: - It was missing <sys/cdefs.h> for __BEGIN_DECLS. - It uses various primitive types that were not declared.

* 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 The superceded interface was never actually released on 7.x. The other main change is to pack the data passed to userland via the sysctl.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.
* Fixed style issues with variable ordering and naming, spacing andSean Farley2008-11-231-75/+97
| | | | | | | | | | | | | | | | | parentheses. Fixed alignment issue in gr_dup() in its assignment of gr_mem using a struct to force alignment without performing alignment mathematics. 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.
