Jim Warner 96e2220068 library: address major bug in the 'listed_nextpid' guy
Ever since 2003, the 'listed_nextpid' routine has been
misrepresenting its duties. Far from finding processes
in a list given to openproc, it just inserted the next
pid in that list into the passed proc_t as BOTH a tgid
and tid. There was no attempt to validate such values.

The net result is that tid & tgid were valid only with
a thread group leader. When called with a pid for some
sibling thread, the resulting tgid would be incorrect.

With this commit, our little function will now attempt
to validate both the tid and tgid. If this should fail
then the fallback position will be the same as what we
inherited. So we're no worse off & likely much better.

[ note that calling the function with a thread's pid ]
[ likely stems from 2011 when a 'readeither' routine ]
[ was added which dealt with both tasks and threads! ]

build status procps

procps is a set of command line and full-screen utilities that provide information out of the pseudo-filesystem most commonly located at /proc. This filesystem provides a simple interface to the kernel data structures. The programs of procps generally concentrate on the structures that describe the processess running on the system.

The following programs are found in procps:

  • free - Report the amount of free and used memory in the system
  • kill - Send a signal to a process based on PID
  • pgrep - List processes based on name or other attributes
  • pkill - Send a signal to a process based on name or other attributes
  • pmap - Report memory map of a process
  • ps - Report information of processes
  • pwdx - Report current directory of a process
  • skill - Obsolete version of pgrep/pkill
  • slabtop - Display kernel slab cache information in real time
  • snice - Renice a process
  • sysctl - Read or Write kernel parameters at run-time
  • tload - Graphical representation of system load average
  • top - Dynamic real-time view of running processes
  • uptime - Display how long the system has been running
  • vmstat - Report virtual memory statistics
  • w - Report logged in users and what they are doing
  • watch - Execute a program periodically, showing output fullscreen

Reporting Bugs

There are a few ways of reporting bugs or feature requests:

  1. Your distributions bug reporter. If you are using a distribution your first port of call is their bug tracker. This is because each distribution has their own patches and way of dealing with bugs. Also bug reporting often does not need any subscription to websites.
  2. GitLab Issues - To the left of this page is the issue tracker. You can report bugs here.
  3. Email list - We have an email list (see below) where you can report bugs. The problem with this method is bug reports often get lost and cannot be tracked. This is especially a big problem when its something that will take time to resolve.

If you need to report bugs, there is more details on the Bug Reporting page.

Email List

The email list for the developers and users of procps is found at http://www.freelists.org/archive/procps/ This email list discusses the development of procps and is used by distributions to also forward or discuss bugs.
