Bug#578568: Request to enable CONFIG_NET_DROP_MONITOR
Package: linux-2.6
Version: 2.6.32-3-amd64
Severity: wishlist
dropwatch is a program to "improve our ability to detect
and understand packets that get dropped within the (network)
stack". See https://fedorahosted.org/dropwatch/ for more info.
dropwatch depends on the kernel-side option NET_DROP_MONITOR:
http://lxr.linux.no/#linux+v2.6.33/net/Kconfig#L238
This enables a netlink-based protocol for monitoring of
dropped network packets.
Arguments for inclusion:
*) Detection of packet drops in the network stack becomes
much more precise.
*) The runtime cost of enabling this feature should be
minimal, in the common case where no userspace applications
have enabled the dropwatch tracepoints. More info can
be found in the upstream patch submission:
http://marc.info/?l=linux-netdev&m=123609949307113&w=2
*) Fedora ships NET_DROP_MONITOR=y and the dropwatch package,
so the config option has received a fair bit of testing.
