[libvirt] [PATCH] Fix libvirtd crash possibility
by Martin Kletzander 13 Sep '12

13 Sep '12

When generating RPC protocol messages, it's strictly needed to have continuousline of numbers or RPC messages. However in case anyone tries backporting some functionality and will skip a number, there is a possibility to make the daemon segfault with newer virsh (version of the library, rpc call, etc.) even unintentionally. The problem is that the skipped numbers will get func filled with NULLs, but there is no check whether these are set before the daemon tries to run them. This patch very simply enhances one check and fixes that. I haven't investigated into such a deepness to say if the possibility comes as well with hacked RPC call (calling event instead of function), but this patch gets rid of both these problems. --- src/rpc/virnetserverprogram.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/src/rpc/virnetserverprogram.c b/src/rpc/virnetserverprogram.c index d13b621..bc85df0 100644 --- a/src/rpc/virnetserverprogram.c +++ b/src/rpc/virnetserverprogram.c @@ -1,7 +1,7 @@ /* * virnetserverprogram.c: generic network RPC server program * - * Copyright (C) 2006-2011 Red Hat, Inc. + * Copyright (C) 2006-2012 Red Hat, Inc. * Copyright (C) 2006 Daniel P.

[libvirt] libvirt build failure w/GNU make and automake.git (automake regression?)

Here's that part of GNU make's documentation: 6.9 Undefining Variables ======================== If you want to clear a variable, setting its value to empty is usually sufficient. Expanding such a variable will yield the same result (empty string) regardless of whether it was set or not. However, if you are using the `flavor' (*note Flavor Function::) and `origin' (*note Origin Function::) functions, there is a difference between a variable that was never set and a variable with an empty value. In such situations you may want to use the `undefine' directive to make a variable appear as if it was never set. For example: foo := foo bar = bar undefine foo undefine bar $(info $(origin foo)) $(info $(flavor bar)) This example will print "undefined" for both variables. If you want to undefine a command-line variable definition, you can use the `override' directive together with `undefine', similar to how this is done for variable definitions: override undefine CFLAGS The most pragmatic work-around is to rename the "undefine" test script. However, Stephano, as automake maintainer, I think you will want to fix automake not to prohibit the use of such test names.

[libvirt] libvirt & git send-email
by Gene Czarcinski 13 Sep '12

13 Sep '12

I have (hopefully) figured out how to use git and have submitted three emails: a cover, updates for IPv4 and updates for IPv6 ... in fact, I have done this twice ... once yesterday around noon and again a few minutes ago. I submitted them today because the emails had not appeared on libvir-lst. So, after sending them today my CC appeared and a minute or so later the patches appeared on the mailing list. BUT, these emails were the ones I sent yesterday, are dated such, have yesterday's subject line (today's was very slightly different), and had the Message-id from yesterday. Yes, both yesterday and today, I tested doing the "git send-email" by specifying some different email addresses I have and I, indeed, received two copies (TO and CC). If anyone knows what happened, please tell me. If I screwed something up, I would like to not do it again. The from email address matches the email address that is subscribed to this list so that should not be the problem. If this remains a mystery, so be it. Gene
