* ip6_tunnel: copy parms.name after register_netdeviceJosh Boyer2011-11-261-1/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | commit 731abb9cb27aef6013ce60808a04e04a545f3f4e upstream. Commit 1c5cae815d removed an explicit call to dev_alloc_name in ip6_tnl_create because register_netdevice will now create a valid name. This works for the net_device itself. However the tunnel keeps a copy of the name in the parms structure for the ip6_tnl associated with the tunnel. parms.name is set by copying the net_device name in ip6_tnl_dev_init_gen. That function is called from ip6_tnl_dev_init in ip6_tnl_create, but it is done before register_netdevice is called so the name is set to a bogus value in the parms.name structure. This shows up if you do a simple tunnel add, followed by a tunnel show: [root@localhost ~]# ip -6 tunnel add remote fec0::100 local fec0::200 [root@localhost ~]# ip -6 tunnel show ip6tnl0: ipv6/ipv6 remote :: local :: encaplimit 0 hoplimit 0 tclass 0x00 flowlabel 0x00000 (flowinfo 0x00000000) ip6tnl%d: ipv6/ipv6 remote fec0::100 local fec0::200 encaplimit 4 hoplimit 64 tclass 0x00 flowlabel 0x00000 (flowinfo 0x00000000) [root@localhost ~]# Fix this by moving the strcpy out of ip6_tnl_dev_init_gen, and calling it after register_netdevice has successfully returned.

The possibility to call dev_alloc_name in advance remains.

| * Make the ip6_tunnel reflect the true mtu.Anders Franzen2010-12-011-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The ip6_tunnel always assumes it consumes 40 bytes (ip6 hdr) of the mtu of the underlaying device. So for a normal ethernet bearer, the mtu of the ip6_tunnel is 1460. However, when creating a tunnel the encap limit option is enabled by default, and it consumes 8 bytes more, so the true mtu shall be 1452. I dont really know if this breaks some statement in some RFC, so this is a request for comments. Signed-off-by: Anders Franzen <anders.franzen@ericsson.com> Signed-off-by: David S.

* tunnels: Fix tunnels change rcu protectionPavel Emelyanov2010-10-271-0/+1
| | | | | | | | | | | | | | | | | | | | | After making rcu protection for tunnels (ipip, gre, sit and ip6) a bug was introduced into the SIOCCHGTUNNEL code. The tunnel is first unlinked, then addresses change, then it is linked back probably into another bucket. But while changing the parms, the hash table is unlocked to readers and they can lookup the improper tunnel. Respective commits are b7285b79 (ipip: get rid of ipip_lock), 1507850b (gre: get rid of ipgre_lock), 3a43be3c (sit: get rid of ipip6_lock) and 94767632 (ip6tnl: get rid of ip6_tnl_lock). The quick fix is to wait for quiescent state to pass after unlinking, but if it is inappropriate I can invent something better, just let me know.

* net: add a core netdev->rx_dropped counterEric Dumazet2010-10-051-2/+1
| | | | | | | | | | | | | | | | | | In various situations, a device provides a packet to our stack and we drop it before it enters protocol stack : - softnet backlog full (accounted in /proc/net/softnet_stat) - bad vlan tag (not accounted) - unknown/unregistered protocol (not accounted) We can handle a per-device counter of such dropped frames at core level, and automatically adds it to the device provided stats (rx_dropped), so that standard tools can be used (ifconfig, ip link, cat /proc/net/dev) This is a generalization of commit 8990f468a (net: rx_dropped accounting), thus reverting it.

* include cleanup: Update gfp.h and slab.h includes to prepare for breaking ↵Tejun Heo2010-03-301-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | implicit slab.h inclusion from percpu.h percpu.h is included by sched.h and module.h and thus ends up being included when building most .c files. percpu.h includes slab.h which in turn includes gfp.h making everything defined by the two files universally available and complicating inclusion dependencies. percpu.h -> slab.h dependency is about to be removed. Prepare for this change by updating users of gfp and slab facilities include those headers directly instead of assuming availability. As this conversion needs to touch large number of source files, the following script is used as the basis of conversion. http://userweb.kernel.org/~tj/misc/slabh-sweep.py The script does the followings. * Scan files for gfp and slab usages and update includes such that only the necessary includes are there. ie. if only gfp is used, gfp.h, if slab is used, slab.h. * When the script inserts a new include, it looks at the include blocks and try to put the new include such that its order conforms to its surrounding. It's put in the include block which contains core kernel includes, in the same order that the rest are ordered - alphabetical, Christmas tree, rev-Xmas-tree or at the end if there doesn't seem to be any matching order. * If the script can't find a place to put a new include (mostly because the file doesn't have fitting include block), it prints out an error message indicating which .h file needs to be added to the file. The conversion was done in the following steps. 1. The initial automatic conversion of all .c files updated slightly over 4000 files, deleting around 700 includes and adding ~480 gfp.h and ~3000 slab.h inclusions. The script emitted errors for ~400 files. 2. Each error was manually checked. Some didn't need the inclusion, some needed manual addition while adding it to implementation .h or embedding .c file was more appropriate for others. This step added inclusions to around 150 files. 3. The script was run again and the output was compared to the edits from #2 to make sure no file was left behind. 4. Several build tests were done and a couple of problems were fixed. e.g. lib/decompress_*.c used malloc/free() wrappers around slab APIs requiring slab.h to be added manually. 5. The script was run on all .h files but without automatically editing them as sprinkling gfp.h and slab.h inclusions around .h files could easily lead to inclusion dependency hell. Most gfp.h inclusion directives were ignored as stuff from gfp.h was usually wildly available and often used in preprocessor macros. Each slab.h inclusion directive was examined and added manually as necessary. 6. percpu.h was updated not to include slab.h. 7. Build test were done on the following configurations and failures were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my distributed build env didn't work with gcov compiles) and a few more options had to be turned off depending on archs to make things build (like ipr on powerpc/64 which failed due to missing writeq). * x86 and x86_64 UP and SMP allmodconfig and a custom test config. * powerpc and powerpc64 SMP allmodconfig * sparc and sparc64 SMP allmodconfig * ia64 SMP allmodconfig * s390 SMP allmodconfig * alpha SMP allmodconfig * um on x86_64 SMP allmodconfig 8. percpu.h modifications were reverted so that it could be applied as a separate patch and serve as bisection point. Given the fact that I had only a couple of failures from tests on step 6, I'm fairly confident about the coverage of this conversion patch. If there is a breakage, it's likely to be something in one of the arch headers which should be easily discoverable easily on most builds of the specific arch.

* ip6tnl: Use on-device stats instead of private ones.Pavel Emelyanov2008-05-211-20/+6
| | | | | | | | This tunnel uses its own private structure and requires separate patch to switch from private stats to on-device ones. Signed-off-by: Pavel Emelyanov <xemul@openvz.org> Signed-off-by: David S. Miller <davem@davemloft.net>
* [IP6TUNNEL]: Allow to create IP6 tunnels in net namespaces.Pavel Emelyanov2008-04-161-0/+3
| | | | | | | | | | And no need in some IPPROTO_XXX enabling, since ipv6 code doesn't have any filtering. So, just set proper net and mark device with NETNS_LOCAL. Signed-off-by: Pavel Emelyanov <xemul@openvz.org> Signed-off-by: David S. Miller <davem@davemloft.net>
* [IP6TUNNEL]: Use proper net instead of init_net stubs.Pavel Emelyanov2008-04-161-11/+15
| | | | | | | | | | | All the ip_route_output_key(), dev_get_by_...() and ipv6_chk_addr() calls are now stubbed with init_net. Fortunately, all the places already have where to get the proper net from. Signed-off-by: Pavel Emelyanov <xemul@openvz.org> Signed-off-by: David S. Miller <davem@davemloft.net>
* [IP6TUNNEL]: Make tunnels hashes per-net.Pavel Emelyanov2008-04-161-29/+34
| | | | | | | | Move hashes in the struct ip6_tnl_net, replace tnls_xxx[] with ip6n->tnlx_xxx[] and handle init and exit appropriately. Signed-off-by: Pavel Emelyanov <xemul@openvz.org> Signed-off-by: David S. Miller <davem@davemloft.net>
* [IP6TUNNEL]: Make the fallback tunnel device per-net.Pavel Emelyanov2008-04-161-24/+24
| | | | | | | | | All the code, that reference it already has the ip6_tnl_net pointer, so s/ip6_fb_tnl_dev/ip6n->fb_tnl_dev/ and move creation/releasing code into net init/exit ops. Signed-off-by: Pavel Emelyanov <xemul@openvz.org> Signed-off-by: David S. Miller <davem@davemloft.net>
