net: ipmr: move struct mr_table and VIF_EXISTS to mroute.h

2015-11-30T20:26:22Z

Move the definitions of VIF_EXISTS() and struct mr_table to mroute.h Signed-off-by: Nikolay Aleksandrov Signed-off-by: David S. Miller

net: ipmr: adjust mroute.h style and drop extern

2015-11-30T20:26:22Z

Remove extra spaces and tabs, adjust function definitions, remove an unnecessary ifdef (already used below, just move code) and drop extern from the functions. Signed-off-by: Nikolay Aleksandrov Signed-off-by: David S. Miller

net: ipmr: remove unused MFC_NOTIFY flag and make the flags enum

2015-11-30T20:26:22Z

MFC_NOTIFY was introduced in kernel 2.1.68 but afaik it hasn't been used and I couldn't find any users currently so just remove it. Only MFC_STATIC is left, so move it into an enum, add a description and use BIT(). Signed-off-by: Nikolay Aleksandrov Signed-off-by: David S. Miller

mcast: define and use MRT[6]_MAX in ip[6]_mroute_opt()

2013-01-21T18:55:14Z

This will ease further addition of new MRT[6]_* values and avoid to update in6.h each time. Note that we reduce the maximum value from 210 to 209, but 210 does not match any known value in ip[6]_mroute_setsockopt().

net: Add compat ioctl support for the ipv4 multicast ioctl SIOCGETSGCNT

2011-01-30T09:14:38Z

SIOCGETSGCNT is not a unique ioctl value as it it maps tio SIOCPROTOPRIVATE +1, which unfortunately means the existing infrastructure for compat networking ioctls is insufficient. A trivial compact ioctl implementation would conflict with: SIOCAX25ADDUID SIOCAIPXPRISLT SIOCGETSGCNT_IN6 SIOCGETSGCNT SIOCRSSCAUSE SIOCX25SSUBSCRIP SIOCX25SDTEFACILITIES To make this work I have updated the compat_ioctl decode path to mirror the the normal ioctl decode path. I have added an ipv4 inet_compat_ioctl function so that I can have ipv4 specific compat ioctls. I have added a compat_ioctl function into struct proto so I can break out ioctls by which kind of ip socket I am using. I have added a compat_raw_ioctl function because SIOCGETSGCNT only works on raw sockets. I have added a ipmr_compat_ioctl that mirrors the normal ipmr_ioctl. This was necessary because unfortunately the struct layout for the SIOCGETSGCNT has unsigned longs in it so changes between 32bit and 64bit kernels. This change was sufficient to run a 32bit ip multicast routing daemon on a 64bit kernel. Reported-by: Bill Fenner Signed-off-by: Eric W. Biederman Signed-off-by: David S. Miller

ipv4: ipmr: support multiple tables

2010-04-13T21:49:34Z

This patch adds support for multiple independant multicast routing instances, named "tables". Userspace multicast routing daemons can bind to a specific table instance by issuing a setsockopt call using a new option MRT_TABLE. The table number is stored in the raw socket data and affects all following ipmr setsockopt(), getsockopt() and ioctl() calls. By default, a single table (RT_TABLE_DEFAULT) is created with a default routing rule pointing to it. Newly created pimreg devices have the table number appended ("pimregX"), with the exception of devices created in the default table, which are named just "pimreg" for compatibility reasons. Packets are directed to a specific table instance using routing rules, similar to how regular routing rules work. Currently iif, oif and mark are supported as keys, source and destination addresses could be supported additionally. Example usage: - bind pimd/xorp/... to a specific table: uint32_t table = 123; setsockopt(fd, IPPROTO_IP, MRT_TABLE, &table, sizeof(table)); - create routing rules directing packets to the new table: # ip mrule add iif eth0 lookup 123 # ip mrule add oif eth0 lookup 123 Signed-off-by: Patrick McHardy Signed-off-by: David S.
