File bsc1063910-use-ulong-for-inode.patch of Package net-tools.5919
Upstream ref: https://github.com/ecki/net-tools/commit/74b2b5487338d65c468f76a7530c8 netstat: fix handling of large socket numbers The kernel really only treats sockets with a value of -1 as an error. The rest are an unsigned quantity. So tweak the nestat lookup to use an unsigned value. patch based on Antonio Galea's work in Debian bug 345331 --- Index: netstat.c =================================================================== --- netstat.c.orig +++ netstat.c @@ -415,15 +415,15 @@ static void prg_cache_clear(void) prg_cache_loaded=0; } -static void extract_type_1_socket_inode(const char lname[], long * inode_p) { +static int extract_type_1_socket_inode(const char lname[], unsigned long * inode_p) { /* If lname is of the form "socket:[12345]", extract the "12345" - as *inode_p.
