* netfilter: nf_conntrack_defrag: check socket type before touching nodefrag flagJiri Olsa2010-09-221-1/+3
| | | | | | | | | | | | | we need to check proper socket type within ipv4_conntrack_defrag function before referencing the nodefrag flag. For example the tun driver receive path produces skbs with AF_UNSPEC socket type, and so current code is causing unwanted fragmented packets going out.

* netfilter: fix ipt_REJECT TCP RST routing for indev == outdevChangli Gao2010-09-221-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ip_route_me_harder can't create the route cache when the outdev is the same with the indev for the skbs whichout a valid protocol set. __mkroute_input functions has this check: 1998 if (skb->protocol != htons(ETH_P_IP)) { 1999 /* Not IP (i.e. ARP). Do not create route, if it is 2000 * invalid for proxy arp. DNAT routes are always valid. 2001 * 2002 * Proxy arp feature have been extended to allow, ARP 2003 * replies back to the same interface, to support 2004 * Private VLAN switch technologies. See arp.c. 2005 */ 2006 if (out_dev == in_dev && 2007 IN_DEV_PROXY_ARP_PVLAN(in_dev) == 0) { 2008 err = -EINVAL; 2009 goto cleanup; 2010 } 2011 } This patch gives the new skb a valid protocol to bypass this check. In order to make ipt_REJECT work with bridges, you also need to enable ip_forward. This patch also fixes a regression. When we used skb_copy_expand(), we didn't have this issue stated above, as the protocol was properly set.

* ip: fix truesize mismatch in ip fragmentationEric Dumazet2010-09-222-11/+26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Special care should be taken when slow path is hit in ip_fragment() : When walking through frags, we transfert truesize ownership from skb to frags. Then if we hit a slow_path condition, we must undo this or risk uncharging frags->truesize twice, and in the end, having negative socket sk_wmem_alloc counter, or even freeing socket sooner than expected. Many thanks to Nick Bowler, who provided a very clean bug report and test program. Thanks to Jarek for reviewing my first patch and providing a V2 While Nick bisection pointed to commit 2b85a34e911 (net: No more expensive sock_hold()/sock_put() on each tx), underlying bug is older (2.6.12-rc5) A side effect is to extend work done in commit b2722b1c3a893e (ip_fragment: also adjust skb->truesize for packets not owned by a socket) to ipv6 as well.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When a driver doesn't fill the entire buffer, old heap contents may remain, and if it also doesn't update the length properly, this old heap content will be copied back to userspace. It is very unlikely that this happens in any of the drivers using private ioctls since it would show up as junk being reported by iwpriv, but it seems better to be safe here, so use kzalloc.

* | xfrm: Allow different selector family in temporary stateThomas Egerer2010-09-204-49/+67
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The family parameter xfrm_state_find is used to find a state matching a certain policy. This value is set to the template's family (encap_family) right before xfrm_state_find is called. The family parameter is however also used to construct a temporary state in xfrm_state_find itself which is wrong for inter-family scenarios because it produces a selector for the wrong family. Since this selector is included in the xfrm_user_acquire structure, user space programs misinterpret IPv6 addresses as IPv4 and vice versa. This patch splits up the original init_tempsel function into a part that initializes the selector respectively the props and id of the temporary state, to allow for differing ip address families whithin the state.

* | ipv4: force_igmp_version ignored when a IGMPv3 query receivedBob Arendt2010-09-131-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | After all these years, it turns out that the /proc/sys/net/ipv4/conf/*/force_igmp_version parameter isn't fully implemented. *Symptom*: When set force_igmp_version to a value of 2, the kernel should only perform multicast IGMPv2 operations (IETF rfc2236). An host-initiated Join message will be sent as a IGMPv2 Join message. But if a IGMPv3 query message is received, the host responds with a IGMPv3 join message. Per rfc3376 and rfc2236, a IGMPv2 host should treat a IGMPv3 query as a IGMPv2 query and respond with an IGMPv2 Join message. *Consequences*: This is an issue when a IGMPv3 capable switch is the querier and will only issue IGMPv3 queries (which double as IGMPv2 querys) and there's an intermediate switch that is only IGMPv2 capable. The intermediate switch processes the initial v2 Join, but fails to recognize the IGMPv3 Join responses to the Query, resulting in a dropped connection when the intermediate v2-only switch times it out. *Identifying issue in the kernel source*: The issue is in this section of code (in net/ipv4/igmp.c), which is called when an IGMP query is received (from mainline 2.6.36-rc3 gitweb): ... A IGMPv3 query has a length >= 12 and no sources. This routine will exit after line 880, setting the general query timer (random timeout between 0 and query response time). This calls igmp_gq_timer_expire(): ... .. which only sends a v3 response. So if a v3 query is received, the kernel always sends a v3 response. IGMP queries happen once every 60 sec (per vlan), so the traffic is low. A IGMPv3 query *is* a strict superset of a IGMPv2 query, so this patch properly short circuit's the v3 behaviour. One issue is that this does not address force_igmp_version=1. Then again, I've never seen any IGMPv1 multicast equipment in the wild. However there is a lot of v2-only equipment. If it's necessary to support the IGMPv1 case as well: 837 if (len == 8 || IGMP_V2_SEEN(in_dev) || IGMP_V1_SEEN(in_dev)) { Signed-off-by: David S. Miller <davem@davemloft.net>

Userspace passes the desired error number as an option in the payload: "#dnserror=<number>" Userspace must map h_errno from the name resolution routines to an appropriate Linux error before passing it up. Something like the following mapping is recommended: [HOST_NOT_FOUND] = ENODATA, [TRY_AGAIN] = EAGAIN, [NO_RECOVERY] = ECONNREFUSED, [NO_DATA] = ENODATA, in lieu of Linux errors specifically for representing name service errors. The filesystem must map these errors appropropriately before passing them to userspace. AFS is made to map ENODATA and EAGAIN to EDESTADDRREQ for the return to userspace; ECONNREFUSED is allowed to stand as is. The error can be seen in /proc/keys as a negative number after the description of the key. Compare, for example, the following key entries: 2f97238c I--Q-- 1 53s 3f010000 0 0 dns_resol afsdb:grand.centrall.org: -61 338bfbbe I--Q-- 1 59m 3f010000 0 0 dns_resol afsdb:grand.central.org: 37 If the error option is supplied in the payload, the main part of the payload is discarded. The key should have an expiry time set by userspace.

The few places which defined their own param types are changed to the new scheme (more which crept in recently fixed in following patches). Since we're touching them anyway, we change get() and set() to take a const struct kernel_param (which they really are). This causes some harmless warnings until we fix them (in following patches). To reduce churn, module_param_call creates the ops struct so the callers don't have to change (and casts the functions to reduce warnings). The modern version which takes an ops struct is called module_param_cb.

With this change, when the workqueue uses a deferrable timer, the do_cache_clean() invocation will be delayed and combined with the closest "real" wake-up. This improves the power consumption situation. Note, I tried to create a DECLARE_DELAYED_WORK_DEFERRABLE() helper macro, similar to DECLARE_DELAYED_WORK(), but failed because of the way the timer wheel core stores the deferrable flag (it is the LSBit in the time->base pointer). My attempt to define a static variable with this bit set ended up with the "initializer element is not constant" error. Thus, I have to use run-time initialization, so I created a new cache_initialize() function which is called once when sunrpc is being initialized.
