* Make pw_scan(3) more compatible with getpwent(3) et. al. when processingIan Lepore2018-07-261-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | data from /etc/passwd rather than /etc/master.passwd. The libc getpwent(3) and related functions automatically read master.passwd when run by root, or passwd when run by a non-root user. When run by non- root, getpwent() copes with the missing data by setting the corresponding fields in the passwd struct to known values (zeroes for numbers, or a pointer to an empty string for literals). When libutil's pw_scan(3) was used to parse a line without the root-accessible data, it was leaving garbage in the corresponding fields. These changes rename the static pw_init() function used by getpwent() and friends to __pw_initpwd(), and move it into pw_scan.c so that common init code can be shared between libc and libutil. pw_scan(3) now calls __pw_initpwd() before __pw_scan(), just like the getpwent() family does, so that reading an arbitrary passwd file in either format and parsing it with pw_scan(3) returns the same results as getpwent(3) would. This also adds a new pw_initpwd(3) function to libutil, so that code which creates passwd structs from scratch in some manner that doesn't involve pw_scan() can initialize the struct to the values expected by lots of existing code, which doesn't expect to encounter NULL pointers or garbage values in some fields.
* lib: further adoption of SPDX licensing ID tags.Pedro F. Giffuni2017-11-261-1/+3
| | | | | | | | | | | | Mainly focus on files that use BSD 2-Clause license, however the tool I was using mis-identified many licenses so this was mostly a manual - error prone - task. The Software Package Data Exchange (SPDX) group provides a specification to make it easier for automated tools to detect and summarize well known opensource licenses. We are gradually adopting the specification, noting that the tags are considered only advisory and do not, in any way, superceed or replace the license texts.

* - 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

* 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

* 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.
