[Kernel-packages] [Bug 1411350] Re: routing table does not show dynamic routes
I have encountered this behaviour on the wily lts kernel in 14.04 (4.2.0-23-generic #28~14.04.1-Ubuntu) However, i have manually added the route via ip route command, e.g. # ip r a 192.168.100.1/32 dev br-ext ip route show shows nothing, but ip route get displays the route. # ip route show | grep 192.168.100.1 # ip route get 192.168.100.1 192.168.100.1 dev br-ext src 10.10.2.2 cache The kernel seems to have this route, as it can be deleted # ip r del 192.168.100.1/32 dev br-ext And if trying to delete it again, I get an error message as expected. # ip r del 192.168.100.1/32 dev br-ext RTNETLINK answers: No such process So I would retitle this bug as "routing table does not always show all routes" -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1411350 Title: routing table does not show dynamic routes Status in linux package in Ubuntu: Confirmed Bug description: Dynamic routes gotten from ICMP-redirect message are not shown in the routing table.

[Kernel-packages] [Bug 1411350] Re: routing table does not show dynamic routes
Also, did this issue start happening after an update/upgrade? Was there a prior kernel version where you were not having this particular problem? Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v3.19 kernel[0]. If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'. If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'. If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'. Once testing of the upstream kernel is complete, please mark this bug as Confirmed. Thanks in advance.
