* Modify pw_copy:Baptiste Daroussin2011-12-151-1/+7
| | | | | | | | | | | | | - 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.
* 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.
* 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | o Incorporated BSDI code and enhancements, better logging for error checking (which has been shown to be a problem, and is therefore justified, imho); also some minor things we were missing, including better quad_t math, which checks for under/overflows. o setusercontext() now allows user resource limit overrides, but does this AFTER dropping root privs, to restrict the user to droping hard limits and set soft limits within the kernel's allowed user limits. o umask() only set once, and only if requested. o add _secure_path(), and use in login.conf to guard against symlinks etc. and non-root owned or non-user owned files being used. Derived from BSDI contributed code. o revamped authentication code to BSDI's latest api, which includes deleting authenticate() and adding auth_check() and a few other functions. This is still marked as depecated in BSDI, but is included for completeness. No other source in the tree uses this anyway, so it is now bracketed with #ifdef LOGIN_CAP_AUTH which is by default not defined. Only auth_checknologin() and auth_cat() are actually used in module login_auth.c. o AUTH_NONE definition removed (collided with other includes in the tree). [bde] o BSDI's login_getclass() now accepts a char *classname parameter rather than struct passwd *pwd. We now do likewise, but added login_getpwclass() for (sort of) backwards compatiblity, namely because we handle root as a special case for the default class. This will require quite a few changes elsewhere in the source tree. o We no longer pretend to support rlim_t as a long type. o Revised code formatting to be more bsd-ish style.
