Re: [Crash-utility] A patch for match_file_string()

Hi Dave,
on some distributions (e.g. Ubuntu) crash cannot find the live kernel image
because of a slight mismatch between kt->proc_version and 'strings' output
from namelist file (e.g. /boot/vmlinux-debug-2.6.22-14-generic)
Namely, kt->proc_version is LF-terminated, but there is no LF in 'strings
vmlinux' output.
If I strip LF from the end of kt->proc_version, everything works fine

Hi Alex,
Help me out here -- when I run it, both kt->proc_version and the buffer
read from the strings output read by fgets() both have linefeeds.
Are you saying that the fgets() call is stripping the linefeed from
the strings output? The "strings vmlinux" output has to have linefeeds
or else it would be a huge mash of characters.
What am I missing?
Dave
