From: Bernard Pidoux F6BVP Date: Thu, 17 Dec 2009 05:25:18 +0000 (+0000) Subject: rose_loopback_timer sets VC number <= ROSE_DEFAULT_MAXVC X-Git-Tag: v2.6.33-rc4~10^2~47 X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=1f731b63752dac76ff4dbf568a08ff2e3663316f;p=karo-tx-linux.git rose_loopback_timer sets VC number <= ROSE_DEFAULT_MAXVC cat /proc/net/rose displayed a rose sockets abnormal lci value, i.e. greater than maximum number of VCs per neighbour allowed. This number prevents further test of lci value during rose operations. Example (lines shortened) : [bernard]# cat /proc/net/rose dest_addr dest_call src_addr src_call dev lci neigh st vs vr va * * 2080175520 F6BVP-1 rose0 000 00000 0 0 0 0 2080175520 FPAD-0 2080175520 WP-0 rose0 FFE 00001 3 0 0 0 Here are the default parameters : linux/include/net/rose.h:#define ROSE_DEFAULT_MAXVC 50 /* Maximum number of VCs per neighbour */ linux/net/rose/af_rose.c:int sysctl_rose_maximum_vcs = ROSE_DEFAULT_MAXVC; With the following patch, rose_loopback_timer() attributes a VC number within limits.
