* vxlan: set needed headroom correctlyJiri Benc2015-09-181-5/+5
| | | | | | | | | | | | | | | | vxlan_setup is called when allocating the net_device, i.e. way before vxlan_newlink (or vxlan_dev_configure) is called. This means vxlan->default_dst is actually unset in vxlan_setup and the condition that sets needed_headroom always takes the else branch. Set the needed_headrom at the point when we have the information about the address family available. Fixes: e4c7ed415387c ("vxlan: add ipv6 support") Fixes: 2853af6a2ea1a ("vxlan: use dev->needed_headroom instead of dev->hard_header_len") CC: Cong Wang <cwang@twopensource.com> Signed-off-by: Jiri Benc <jbenc@redhat.com> Signed-off-by: David S.

* ARCNET: fix hard_header_len limitMichael Grzeschik2015-09-181-1/+1
| | | | | | | | | | | | | | | | For arcnet the bare minimum header only contains the 4 bytes to specify source, dest and offset (1, 1 and 2 bytes respectively). The corresponding struct is struct arc_hardware. The struct archdr contains additionally a union of possible soft headers. When doing $insertusecasehere packets might well include short (or even no?) soft headers. For this reason only use arc_hardware instead of archdr to determine the hard_header_len for an arcnet device. Signed-off-by: Michael Grzeschik <m.grzeschik@pengutronix.de> Signed-off-by: David S.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | There are several actions that smp_conn_security() might make that do not require a valid SMP context (conn->smp pointer). One of these actions is to encrypt the link with an existing LTK. If the SMP context wasn't initialized properly we should still allow the independent actions to be done, i.e. the check for the context should only be done at the last possible moment.

Which is reasonable, being the Solos ADSL card's header of 8 bytes followed by 2 bytes of PPP frame type. The problem is that if netfilter ipv6 defragmentation is used, skb_cow() in ip6_forward will only see reassembled skb. Therefore, headroom is overestimated by 8 bytes (we pulled fragment header) and we don't check the skbs in the frag_list either. We can't do these checks in netfilter defrag since outdev isn't known yet. Furthermore, existing tests in ip6_fragment did not consider the fragment or ipv6 header size when checking headroom of the fraglist skbs. While at it, also fix a skb leak on memory allocation -- ip6_fragment must consume the skb. I tested this e1000 driver hacked to not allocate additional headroom (we end up in slowpath, since LL_RESERVED_SPACE is 16). If 2 bytes of headroom are allocated, fastpath is taken (14 byte ethernet header was pulled, so 16 byte headroom available in all fragments).

* | solos-pci: Increase headroom on received packetsDavid Woodhouse2015-09-181-2/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A comment in include/linux/skbuff.h says that: * Various parts of the networking layer expect at least 32 bytes of * headroom, you should not reduce this. This was demonstrated by a panic when handling fragmented IPv6 packets: http://marc.info/?l=linux-netdev&m=144236093519172&w=2 It's not entirely clear if that comment is still valid — and if it is, perhaps netif_rx() ought to be enforcing it with a warning. But either way, it is rather stupid from a performance point of view for us to be receiving packets into a buffer which doesn't have enough room to prepend an Ethernet header — it means that *every* incoming packet is going to be need to be reallocated.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Steffen reported that the recent change to add oif to dst lookups breaks the VTI use case. The problem is that with the oif set in the flow struct the comparison to the nh_oif is triggered. Fix by splitting the FLOWI_FLAG_VRFSRC into 2 flags -- one that triggers the vrf device cache bypass (FLOWI_FLAG_VRFSRC) and another telling the lookup to not compare nh oif (FLOWI_FLAG_SKIP_NH_OIF).

* openvswitch: Fix mask generation for nested attributes.Jesse Gross2015-09-161-23/+59
| | | | | | | | | | | | | | | | | | | | Masks were added to OVS flows in a way that was backwards compatible with userspace programs that did not generate masks. As a result, it is possible that we may receive flows that do not have a mask and we need to synthesize one. Generating a mask requires iterating over attributes and descending into nested attributes. For each level we need to know the size to generate the correct mask. We do this with a linked table of attribute types. Although the logic to handle these nested attributes was there in concept, there are a number of bugs in practice. Examples include incomplete links between tables, variable length attributes being treated as nested and missing sanity checks.

The following is a common paradigm: if (ip6_del_rt(rt)) dst_free(rt) which means, if rt cannot be deleted from the fib tree, dst_free(rt) now. 1. We don't know the ip6_del_rt(rt) failure is because it was not managed by fib tree (e.g. DST_NOCACHE) or it had already been removed from the fib tree. 2. If rt had been managed by the fib tree, ip6_del_rt(rt) failure means dst_free(rt) has been called already. A second dst_free(rt) is not always obviously safe. The rt may have been destroyed already. 3. If rt is a DST_NOCACHE, dst_free(rt) should not be called. 4. It is a stopper to make dst freeing from fib tree undergo a rcu grace period. This patch is to use a DST_NOCACHE flag to indicate a rt is not managed by the fib tree. Signed-off-by: Martin KaFai Lau <kafai@fb.com> Signed-off-by: David S. Miller <davem@davemloft.net>

F.e. the same dst_cache can be released multiple times and then triggering the infamous dst refcnt < 0 warning message. - Another issue is the inconsistency between dst_cache and dst_cookie. It can be reproduced by adding and removing the ip6gre tunnel while running a super_netperf TCP_CRR test. 2. ip6_tnl_dst_get does not take the dst refcnt before returning the dst. This patch: 1. Create a percpu dst_entry cache in ip6_tnl 2.

* bnx2x: use ktime_get_seconds() for timestampArnd Bergmann2015-09-121-4/+2
| | | | | | | | | | | | | | | | | | | | | | commit c48f350ff5e7 "bnx2x: Add MFW dump support" added the bnx2x_update_mfw_dump() function that reads the current time and stores it in a 32-bit field that gets passed into a buffer in a fixed format. This is potentially broken when the epoch overflows in 2038, and otherwise overflows in 2106. As we're trying to avoid uses of struct timeval for this reason, I noticed the addition of this function, and tried to rewrite it in a way that is more explicit about the overflow and that will keep working once we deprecate struct timeval. I assume that it is not possible to change the ABI any more, otherwise we should try to use a 64-bit field for the seconds right away.

* sctp: fix race on protocol/netns initializationMarcelo Ricardo Leitner2015-09-121-23/+41

During initialization, sctp will add the new protocol type and then initialize pernet subsys: status = sctp_v4_protosw_init(); if (status) goto err_protosw_init; status = sctp_v6_protosw_init(); if (status) goto err_v6_protosw_init; status = register_pernet_subsys(&sctp_net_ops); The problem is that after those calls to sctp_v{4,6}_protosw_init(), it is possible for userspace to create SCTP sockets like if the module is already fully loaded. If that happens, one of the possible effects is that we will have readers for net->sctp.local_addr_list list earlier than expected and sctp_net_init() does not take precautions while dealing with that list, leading to a potential panic but not limited to that, as sctp_sock_init() will copy a bunch of blank/partially initialized values from net->sctp. The race happens like this: CPU 0 | CPU 1 socket() | __sock_create | socket() inet_create | __sock_create list_for_each_entry_rcu( | answer, &inetsw[sock->type], | list) { | inet_create /* no hits */ | if (unlikely(err)) { | ... | request_module() | /* socket creation is blocked | * the module is fully loaded | */ | sctp_init | sctp_v4_protosw_init | inet_register_protosw | list_add_rcu(&p->list, | last_perm); | | list_for_each_entry_rcu( | answer, &inetsw[sock->type], sctp_v6_protosw_init | list) { | /* hit, so assumes protocol | * is already loaded | */ | /* socket creation continues | * before netns is initialized | */ register_pernet_subsys | Simply inverting the initialization order between register_pernet_subsys() and sctp_v4_protosw_init() is not possible because register_pernet_subsys() will create a control sctp socket, so the protocol must be already visible by then. Deferring the socket creation to a work-queue is not good specially because we loose the ability to handle its errors. So, as suggested by Vlad, the fix is to split netns initialization in two moments: defaults and control socket, so that the defaults are already loaded by when we register the protocol, while control socket initialization is kept at the same moment it is today.

| | | | | | | | | | | | | | | Instead of always emitting BPF_REG_X, let's emit BPF_REG_X only when the source actually is BPF_X. This causes programs generated by the classic converter to not be importable via bpf(), as the eBPF verifier checks that the src_reg is correct or 0. While not a problem yet, this will be a problem when BPF_PROG_DUMP lands, and we can potentially dump and re-import programs generated by the converter.

* netlink, mmap: transform mmap skb into full skb on tapsDaniel Borkmann2015-09-112-7/+32
| | | | | | | | | | | | | | | | | | | | | | | | | | Ken-ichirou reported that running netlink in mmap mode for receive in combination with nlmon will throw a NULL pointer dereference in __kfree_skb() on nlmon_xmit(), in my case I can also trigger an "unable to handle kernel paging request". The problem is the skb_clone() in __netlink_deliver_tap_skb() for skbs that are mmaped. I.e. the cloned skb doesn't have a destructor, whereas the mmap netlink skb has it pointed to netlink_skb_destructor(), set in the handler netlink_ring_setup_skb(). There, skb->head is being set to NULL, so that in such cases, __kfree_skb() doesn't perform a skb_release_data() via skb_release_all(), where skb->head is possibly being freed through kfree(head) into slab allocator, although netlink mmap skb->head points to the mmap buffer. Similarly, the same has to be done also for large netlink skbs where the data area is vmalloced. Therefore, as discussed, make a copy for these rather rare cases for now. This fixes the issue on my and Ken-ichirou's test-cases.
