Subject: Issues with Linux 3.0.1 and network-interface-list
Date: Thu, 18 Aug 2011 16:20:07 +0200 [thread overview]
Message-ID: <87wrea244o.fsf@tsdh.uni-koblenz.de> (raw)
Hi all,
does someone else also have issues with `network-interface-list' with
kernel version 3.0.1? For me, sometimes that function returns nil,
although a second earlier and again a second later, it'll return a list
of eth0 and lo...
For example, with "strace -e ioctl emacs -Q" and then evaluating
--8<---------------cut here---------------start------------->8---
(while t
(let ((ifs (network-interface-list)))
(if ifs
(message "Ok")
(error "ifs"))))
--8<---------------cut here---------------end--------------->8---
in *scratch*, I first get some 100th Oks and then an error... The
strace output is:
--8<---------------cut here---------------start------------->8---
ioctl(15, SIOCGIFCONF, {80, {{"lo", {AF_INET, inet_addr("127.0.0.1")}}, {"eth0", {AF_INET, inet_addr("141.26.67.142")}}}}) = 0
ioctl(15, SIOCGIFCONF, {80, {{"lo", {AF_INET, inet_addr("127.0.0.1")}}, {"eth0", {AF_INET, inet_addr("141.26.67.142")}}}}) = 0
ioctl(15, SIOCGIFCONF, {80, {{"lo", {AF_INET, inet_addr("127.0.0.1")}}, {"eth0", {AF_INET, inet_addr("141.26.67.142")}}}}) = 0
[...]
ioctl(15, SIOCGIFCONF, {0, {}})
--8<---------------cut here---------------end--------------->8---
It looks like a kernel bug, right?
(If someone can reproduce that and has some C- and kernel-fu, it would
be great if he could report that at the kernel bugtracker. I don't have
any...)
Bye,
Tassilo
