* [NETNS]: Remove empty ->init callback.Pavel Emelyanov2008-04-211-7/+0Star
| | | | | | | | The netns start-stop engine can happily live with any of init or exit callbacks set to NULL. Signed-off-by: Pavel Emelyanov <xemul@openvz.org> Signed-off-by: David S. Miller <davem@davemloft.net>
* [NETNS]: Don't initialize err variable twice.Pavel Emelyanov2008-04-211-2/+1Star
| | | | | | | The ip6_route_net_init() performs some unneeded actions. Signed-off-by: Pavel Emelyanov <xemul@openvz.org> Signed-off-by: David S. Miller <davem@davemloft.net>
* [NETNS]: The ip6_fib_timer can work with garbage on net namespace stop.Pavel Emelyanov2008-04-211-1/+1
| | | | | | | | | | | | | | The del_timer() function doesn't guarantee, that the timer callback is not active by the time it exits. Thus, the fib6_net_exit() may kfree() all the data, that is required by the fib6_run_gc(). The race window is tiny, but slab poisoning can trigger this bug. Using del_timer_sync() will cure this.

* [IPV6]: Fix dangling references on error in fib6_add().David S. Miller2008-04-181-0/+4
| | | | | | | | | | | | | | | Fixes bugzilla #8895 If a super-tree leaf has 'rt' assigned to it and we get an error from fib6_add_rt2node(), we'll leave a reference to 'rt' in pn->leaf and then do an unconditional dst_free(). We should prune such references. Based upon a report by Vincent Perrier. Signed-off-by: David S. Miller <davem@davemloft.net>
* [INET]: Drop the inet_inherit_port() call.Pavel Emelyanov2008-04-181-1/+1
| | | | | | | | | | | | | | | As I can see from the code, two places (tcp_v6_syn_recv_sock and dccp_v6_request_recv_sock) that call this one already run with BHs disabled, so it's safe to call __inet_inherit_port there. Besides (in case I missed smth with code review) the calltrace tcp_v6_syn_recv_sock `- tcp_v4_syn_recv_sock `- __inet_inherit_port and the similar for DCCP are valid, but assumes BHs to be disabled.

| * [NETFILTER]: {ip,ip6,arp}_tables: return EAGAIN for invalid SO_GET_ENTRIES sizePatrick McHardy2008-04-141-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Rule dumping is performed in two steps: first userspace gets the ruleset size using getsockopt(SO_GET_INFO) and allocates memory, then it calls getsockopt(SO_GET_ENTRIES) to actually dump the ruleset. When another process changes the ruleset in between the sizes from the first getsockopt call doesn't match anymore and the kernel aborts. Unfortunately it returns EAGAIN, as for multiple other possible errors, so userspace can't distinguish this case from real errors. Return EAGAIN so userspace can retry the operation.

| | | | | | | | | | | | | | | | | | | | | | | | Fixes kernel bugzilla 10437 Based almost entirely upon a patch by Dmitry Butskoy.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Anycast DST entries allocated inside ipv6_dev_ac_inc are leaked when network device is stopped without removing IPv6 addresses from it. The bug has been observed in the reality on 2.6.18-rhel5 kernel. In the above case addrconf_ifdown marks all entries as obsolete and ip6_del_rt called from __ipv6_dev_ac_dec returns ENOENT. The referrence is not dropped. The fix is simple. DST entry should not keep referrence when stored in the FIB6 tree. Signed-off-by: Denis V. Lunev <den@openvz.org> Signed-off-by: David S.

It the latter case inet6_dev from loopback device should be destroyed. Signed-off-by: Denis V. Lunev <den@openvz.org> Signed-off-by: David S. Miller <davem@davemloft.net>
| * [ICMP]: Ensure that ICMP relookup maintains status quoHerbert Xu2008-04-031-10/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The ICMP relookup path is only meant to modify behaviour when appropriate IPsec policies are in place and marked as requiring relookups. It is certainly not meant to modify behaviour when IPsec policies don't exist at all. However, due to an oversight on the error paths existing behaviour may in fact change should one of the relookup steps fail. This patch corrects this by redirecting all errors on relookup failures to the previous code path. That is, if the initial xfrm_lookup let the packet pass, we will stand by that decision should the relookup fail due to an error. This should be safe from a security point-of-view because compliant systems must install a default deny policy so the packet would'nt have passed in that case.
