a sysctl for process binary osreldate
Hi, Currently we can check and change binary osreldate of another process via procfs(5). Kostik suggested to add a new sysctl for the same purpose and also extend procstat to show osrel. Here are patches I am going to commit if there are no objections or suggestions. http://people.freebsd.org/~trociny/kern_proc_osrel.1.patch http://people.freebsd.org/~trociny/procstat.osrel.1.patch I set the same permissions as for procfs(5) osrel -- so only user can read it, but may be this is too restrictive and p_cansee on read would be ok? I added osrel output to procstat -b option: kopusha:~% procstat -b 2975 PID COMMOSREL PATH 2975 emacs 101 /usr/local/bin/emacs-23.3 Would this be ok or someone see a better way? -- Mikolaj Golub ___ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "freebsd-hackers-unsubscr...@freebsd.org"

Hi, installed 9.0 x64 yesterday and de0 comes up fine when booting.

Support for writing the field seems to violate the synchronisation protocol defined for p_osrel in proc.h. In the new world order, is this simply a documentation bug, or is it also a software bug?

I do not see why the merge to stable/8 cannot be done from the technical POV. If Mikolaj has no time or desire to merge to 8, I can help him. pgpnFp2NSf6SI.pgp Description: PGP signature

Hmm, this means that procstat is not supposed to be used from scripts as it is apparently OK to change its output format like this? In some ways, querying via ps would be better for scripts since it allows things like ps -p PID -o KEYWORD= which do not need additional parsing except that many of the newer things in procstat do not have ps keywords. -- Jilles Tjoelker ___ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "freebsd-hackers-unsubscr...@freebsd.org"

It would be nice to see this information on running procs to verify there is not some old running binary that was left behind in an upgrade. -- ;s =; ___ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "freebsd-hackers-unsubscr...@freebsd.org"
