It's nicer to return void, since then there's no need to cast to any structures. Currently none of the users have a cast, but a number of future conversions do. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: David S. Miller <davem@davemloft.net>

Software implementation of transport layer security, implemented using ULP infrastructure. tcp proto_ops are replaced with tls equivalents of sendmsg and sendpage. Only symmetric crypto is done in the kernel, keys are passed by setsockopt after the handshake is complete. All control messages are supported via CMSG data - the actual symmetric encryption is the same, just the message type needs to be passed separately. For user API, please see Documentation patch. Pieces that can be shared between hw and sw implementation are in tls_main.c Signed-off-by: Boris Pismenny <borisp@mellanox.com> Signed-off-by: Ilya Lesokhin <ilyal@mellanox.com> Signed-off-by: Aviad Yehezkel <aviadye@mellanox.com> Signed-off-by: Dave Watson <davejwatson@fb.com> Signed-off-by: David S.

Pull networking fixes from David Miller:
1) The netlink attribute passed in to dev_set_alias() is not
necessarily NULL terminated, don't use strlcpy() on it. From
Alexander Potapenko.
2) Fix implementation of atomics in arm64 bpf JIT, from Daniel
Borkmann.
3) Correct the release of netdevs and driver private data in certain
circumstances.
4) Sanitize netlink message length properly in decnet, from Mateusz
Jurczyk.
5) Don't leak kernel data in rtnl_fill_vfinfo() netlink blobs. From
Yuval Mintz.

Currently, verifier will reject a program if it contains an
narrower load from the bpf context structure. For example,
__u8 h = __sk_buff->hash, or
__u16 p = __sk_buff->protocol
__u32 sample_period = bpf_perf_event_data->sample_period
which are narrower loads of 4-byte or 8-byte field.
This patch solves the issue by:
. Introduce a new parameter ctx_field_size to carry the
field size of narrower load from prog type
specific *__is_valid_access validator back to verifier.
. The non-zero ctx_field_size for a memory access indicates
(1). underlying prog type specific convert_ctx_accesses
supporting non-whole-field access
(2). the current insn is a narrower or whole field access.
. In verifier, for such loads where load memory size is
less than ctx_field_size, verifier transforms it
to a full field load followed by proper masking.
. Currently, __sk_buff and bpf_perf_event_data->sample_period
are supporting narrowing loads.
. Narrower stores are still not allowed as typical ctx stores
are just normal stores.
Because of this change, some tests in verifier will fail and
these tests are removed. As a bonus, rename some out of bound
__sk_buff->cb access to proper field name and remove two
redundant "skb cb oob" tests.

The of_mdio_parse_addr() helper function is useful to other code, but
the module dependency chain causes issues. To work around this, we can
move of_mdio_parse_addr() to be an inline function in the header file.
This gets rid of the dependencies and still allows for the reuse of
code.

Let drivers advertise support for station-mode 4-way handshake offloading with a new NL80211_EXT_FEATURE_4WAY_HANDSHAKE_STA_PSK flag. Extend use of NL80211_ATTR_PMK attribute indicating it might be passed as part of NL80211_CMD_CONNECT command, and contain the PSK (which is the PMK, hence the name.) The driver/device is assumed to handle the 4-way handshake by itself in this case (including key derivations, etc.), instead of relying on the supplicant.

Since UDP no more uses sk->destructor, we can clear completely the skb head state before enqueuing. Amend and use skb_release_head_state() for that. All head states share a single cacheline, which is not normally used/accesses on dequeue. We can avoid entirely accessing such cacheline implementing and using in the UDP code a specialized skb free helper which ignores the skb head state. This saves a cacheline miss at skb deallocation time. v1 -> v2: replaced secpath_reset() with skb_release_head_state() Signed-off-by: Paolo Abeni <pabeni@redhat.com> Acked-by: Eric Dumazet <edumazet@google.com> Signed-off-by: David S.

This series provides updates to mlx5 header rewrite feature, from Or Gerlitz. and three more small updates From maor and eran. ------- Or says: Packets belonging to flows which are different by matching may still need to go through the same header re-writes (e.g set the current routing hop MACs and issue TTL decrement). To minimize the number of modify header IDs, we add a cache for header re-write IDs which is keyed by the binary chain of modify header actions. The caching is supported for both eswitch and NIC use-cases, where the actual conversion of the code to use caching comes in separate patches, one per use-case. Using a per field mask field, the TC pedit action supports modifying partial fields. The last patch enables offloading that. ------- From Maor, update flow table commands layout to the latest HW spec. From Eran, ethtool connector type reporting updates.

LL2 today is interrupt driven - when tx/rx completion arrives [or any other indication], qed needs to operate on the connection and pass the information to the protocol-driver [or internal qed consumer]. Since we have several flavors of ll2 employeed by the driver, each handler needs to do an if-else to determine the right functionality to use based on the connection type. In order to make things more scalable [given that we're going to add additional types of ll2 flavors] move the infrastrucutre into using a callback-based approach - the callbacks would be provided as part of the connection's initialization parameters.

A LL2 connection [qed_ll2_info] has a sub-structure of type qed_ll2_conn that contain various inputs for ll2 acquisition, but the connection also utilizes a couple of other inputs. Restructure the input structure to include all the inputs and refactor the code necessary to populate those. Signed-off-by: Yuval Mintz <Yuval.Mintz@cavium.com> Signed-off-by: David S.

The ipvlan code already knows how to detect when a duplicate address is about to be assigned to an ipvlan device. However, that failure is not propogated outward and leads to a silent failure. Introduce a validation step at ip address creation time and allow device drivers to register to validate the incoming ip addresses. The ipvlan code is the first consumer. If it detects an address in use, we can return an error to the user before beginning to commit the new ifa in the networking code. This can be especially useful if it is necessary to provision many ipvlans in containers. The provisioning software (or operator) can use this to detect situations where an ip address is unexpectedly in use. Signed-off-by: Krister Johansen <kjlx@templeofstupid.com> Signed-off-by: David S.

While a 'struct key' itself normally does not contain sensitive
information, Documentation/security/keys.txt actually encourages this:
"Having a payload is not required; and the payload can, in fact,
just be a value stored in the struct key itself."
In case someone has taken this advice, or will take this advice in the
future, zero the key structure before freeing it. We might as well, and
as a bonus this could make it a bit more difficult for an adversary to
determine which keys have recently been in use.
This is safe because the key_jar cache does not use a constructor.

Merge tag 'rxrpc-rewrite-20170607-v2' of git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs
David Howells says:
====================
rxrpc: Tx length parameter
Here's a set of patches that allows someone initiating a client call with
AF_RXRPC to indicate upfront the total amount of data that will be
transmitted. This will allow AF_RXRPC to encrypt directly from source
buffer to packet rather than having to copy into the buffer and only
encrypt when it's full (the encrypted portion of the packet starts with a
length and so we can't encrypt until we know what the length will be).
The three patches are:
(1) Provide a means of finding out what control message types are actually
supported. EINVAL is reported if an unsupported cmsg type is seen, so
we don't want to set the new cmsg unless we know it will be accepted.
(2) Consolidate some stuff into a struct to reduce the parameter count on
the function that parses the cmsg buffer.
(3) Introduce the RXRPC_TX_LENGTH cmsg. This can be provided on the first
sendmsg() that contributes data to a client call request or a service
call reply. If provided, the user must provide exactly that amount of
data or an error will be incurred.
Changes in version 2:
(*) struct rxrpc_send_params::tx_total_len should be s64 not u64. Thanks to
Julia Lawall for reporting this.

Linu Cherian reported a WARN in cleanup_srcu_struct() when shutting down a guest running iperf on a VFIO assigned device. This happens because irqfd_wakeup() calls srcu_read_lock(&kvm->irq_srcu) in interrupt context, while a worker thread does the same inside kvm_set_irq(). If the interrupt happens while the worker thread is executing __srcu_read_lock(), updates to the Classic SRCU ->lock_count[] field or the Tree SRCU ->srcu_lock_count[] field can be lost. The docs say you are not supposed to call srcu_read_lock() and srcu_read_unlock() from irq context, but KVM interrupt injection happens from (host) interrupt context and it would be nice if SRCU supported the use case. KVM is using SRCU here not really for the "sleepable" part, but rather due to its IPI-free fast detection of grace periods. It is therefore not desirable to switch back to RCU, which would effectively revert commit

Roopa reported attempts to delete a bond device that is referenced in a
multipath route is hanging:
$ ifdown bond2 # ifupdown2 command that deletes virtual devices
unregister_netdevice: waiting for bond2 to become free. Usage count = 2
Steps to reproduce:
echo 1 > /proc/sys/net/ipv6/conf/all/ignore_routes_with_linkdown
ip link add dev bond12 type bond
ip link add dev bond13 type bond
ip addr add 2001:db8:2::0/64 dev bond12
ip addr add 2001:db8:3::0/64 dev bond13
ip route add 2001:db8:33::0/64 nexthop via 2001:db8:2::2 nexthop via 2001:db8:3::2
ip link del dev bond12
ip link del dev bond13
The root cause is the recent change to keep routes on a linkdown. Update
the check to detect when the device is unregistering and release the
route for that case.

Network devices can allocate reasources and private memory using netdev_ops->ndo_init(). However, the release of these resources can occur in one of two different places. Either netdev_ops->ndo_uninit() or netdev->destructor(). The decision of which operation frees the resources depends upon whether it is necessary for all netdev refs to be released before it is safe to perform the freeing. netdev_ops->ndo_uninit() presumably can occur right after the NETDEV_UNREGISTER notifier completes and the unicast and multicast address lists are flushed. netdev->destructor(), on the other hand, does not run until the netdev references all go away. Further complicating the situation is that netdev->destructor() almost universally does also a free_netdev(). This creates a problem for the logic in register_netdevice(). Because all callers of register_netdevice() manage the freeing of the netdev, and invoke free_netdev(dev) if register_netdevice() fails. If netdev_ops->ndo_init() succeeds, but something else fails inside of register_netdevice(), it does call ndo_ops->ndo_uninit(). But it is not able to invoke netdev->destructor(). This is because netdev->destructor() will do a free_netdev() and then the caller of register_netdevice() will do the same. However, this means that the resources that would normally be released by netdev->destructor() will not be. Over the years drivers have added local hacks to deal with this, by invoking their destructor parts by hand when register_netdevice() fails. Many drivers do not try to deal with this, and instead we have leaks. Let's close this hole by formalizing the distinction between what private things need to be freed up by netdev->destructor() and whether the driver needs unregister_netdevice() to perform the free_netdev(). netdev->priv_destructor() performs all actions to free up the private resources that used to be freed by netdev->destructor(), except for free_netdev(). netdev->needs_free_netdev is a boolean that indicates whether free_netdev() should be done at the end of unregister_netdevice(). Now, register_netdevice() can sanely release all resources after ndo_ops->ndo_init() succeeds, by invoking both ndo_ops->ndo_uninit() and netdev->priv_destructor(). And at the end of unregister_netdevice(), we invoke netdev->priv_destructor() and optionally call free_netdev(). Signed-off-by: David S. Miller <davem@davemloft.net>

Provide a control message that can be specified on the first sendmsg() of a client call or the first sendmsg() of a service response to indicate the total length of the data to be transmitted for that call. Currently, because the length of the payload of an encrypted DATA packet is encrypted in front of the data, the packet cannot be encrypted until we know how much data it will hold. By specifying the length at the beginning of the transmit phase, each DATA packet length can be set before we start loading data from userspace (where several sendmsg() calls may contribute to a particular packet). An error will be returned if too little or too much data is presented in the Tx phase. Signed-off-by: David Howells <dhowells@redhat.com>

GCC explicitly does not warn for unused static inline functions for -Wunused-function. The manual states: Warn whenever a static function is declared but not defined or a non-inline static function is unused. Clang does warn for static inline functions that are unused. It turns out that suppressing the warnings avoids potentially complex #ifdef directives, which also reduces LOC. Suppress the warning for clang.

A single BPF_OBJ_GET_INFO_BY_FD cmd is used to obtain the info for both bpf_prog and bpf_map. The kernel can figure out the fd is associated with a bpf_prog or bpf_map. The suggested struct bpf_prog_info and struct bpf_map_info are not meant to be a complete list and it is not the goal of this patch. New fields can be added in the future patch. The focus of this patch is to create the interface, BPF_OBJ_GET_INFO_BY_FD cmd for exposing the bpf_prog's and bpf_map's info. The obj's info, which will be extended (and get bigger) over time, is separated from the bpf_attr to avoid bloating the bpf_attr.
