Default Bug#506424: linux-image-2.6.26: copying /proc/*/pagemap leads to resource consumption because of uninitialized struct

Subject: linux-image-2.6.26: copying /proc/*/pagemap leads to resource consumption because of uninitialized struct
Package: linux-image-2.6.26-1-amd64
Version: 2.6.26-10
Severity: normal
File: linux-image-2.6.26

*** Please type your report below this line ***

The VMware support script copies various files from /proc to the report directory. Copying
/proc/*/pagemap takes forever and produces a large file, probably filled with garbage.

Steps to reproduce:
# cp /proc/self/pagemap /tmp/self.pagemap

I found a LKML thread regarding the problem:
http://lkml.indiana.edu/hypermail/linux/kernel/0807.2/0262.html

Is this issue really reproducible with the version you reported, i.e. 2.6.26-10?

This issue was fixed in 2.6.26.1, which is included in that version and I can't
reproduce the problem with that version.

Cheers,
Moritz
