Date: Mon, 3 Feb 2014 10:31:47 -0000 (GMT) From: "Vic" <kernel@...r.org.uk> To: netdev@...r.kernel.org Subject: Bug in IPv4 version of ping... Hi All. I hope this is the right place to post this - this list is mentioned as the mailing list for iputils. I believe I've found a bug in ping.c - there is an ancient work-around for an IP_RECVERR bug in raw sockets. The problem is as follows :- ping_common.c defines a variable working_recverr ping.c uses this variable to work out what it should do under certain failure circumstances. As far as I can see, working_recverr is undefined when first used; the initial response to it could be either way. This leads to an erroneous report that the kernel is "not very fresh", and needs to be upgraded. I have seen this in the current builds for RHEL5 and 6 (s20071127) and in the current release (s20121221). I suspect this variable should be set somewhere after option parsing...
