Description Dennis Schridde 2011-12-13 21:20:39 UTC
When I run lsof on e.g. /usr, it will only list binaries, i.e. files in /usr/{bin,sbin,libexec}, but no libraries, i.e. files in /usr/lib{32,64}. Some time ago this still worked. Currently /proc/*/maps also lists libraries, so theoretically it seems possible to get that information.

Reproducible: Always

post the actual commands you're running

lsof /usr
Previously this showed libraries, too.
Comment 3 SpanKY gentoo-dev 2011-12-14 20:38:59 UTC
that shows nothing at all for me.  is your /usr a sep mount point ?

Yes, it is.
Comment 5 Dennis Schridde 2011-12-16 16:08:14 UTC
I went back as far as sys-process/lsof-4.82 and still it lists no libraries. Hence I assume it must be either a kernel config option (even though I am just doing "make oldconfig" since quite a while) or it has trouble when compiled with a 3.x kernel.

Another idea: It could be caused by btrfs. Maybe that reports open libraries differently to /proc?

P.S: I started to debug it and it seems that it examines the files correctly in process_proc_map(), but they are still missing in the output. Maybe somewhere later the libraries are being filtered for some reason.

did you get any further on this ?

Nope, I will probably start another debugging / source-code-reading session when I have more time in a few days.

A year and a half has passed, and no follow-up has been provided. Please reopen the bug if you decide to continue the troubleshooting process.
