Hello,
I was upgrading multipath-tools and noticed our old config causes the
various programs to segfault in libmultipath. The culprit appeared to
be our blacklist entries with a vendor listed but no product (for
filtering the local disk controllers), e.g:
blacklist {
device {
vendor "LSILOGIC"
}
}
Adding a product of .* makes things work as expected, but this
shouldn't be necessary. It looks like this is because compiling the
product regex is optional:
http://git.opensvc.com/gitweb.cgi?p=multipath-tools/.git;a=blob;f=libmultipath/blacklist.c;h=3f9e80b6bf92502ce01a4a287d17039a1ad9c2ce;hb=HEAD#l89
But the regexec is not:
http://git.opensvc.com/gitweb.cgi?p=multipath-tools/.git;a=blob;f=libmultipath/blacklist.c;h=3f9e80b6bf92502ce01a4a287d17039a1ad9c2ce;hb=HEAD#l151
I couldn't find any posts about this and it didn't look fixed yet,
so I figured I should report the issue.
