When the driver is configured as kernel module and when it gets unloaded and reloaded, kernel crash was observed. This patch addresses the software cleanup by doing the following, - Moved register_netdev call after hardware is ready - Since ndev is not ready, added set_irq_name to set irq name - Since ndev is not ready, changed mdio_bus->parent to pdev->dev - Replaced netif_start(stop)_queue by netif_tx_start(stop)_queues - Removed napi_del call since it's called by free_netdev - Added dev_close call, within remove - Added shutdown callback - Changed to use dmam_ APIs Signed-off-by:

Since mac_init is too heavy to be called when the link changes, moved the speed_set configuration to a new function and added mac_ops->set_speed function pointer. This function will be called from adjust_link callback. Added cases for 10/100 support for SGMII based 1G interface. Signed-off-by:

WANG Cong authored
After the previous patch, struct tc_action should be enough to represent the generic tc action, tcf_common is not necessary any more. This patch gets rid of it to make tc action code more readable. Cc: Jamal Hadi Salim <jhs@mojatatu.com> Signed-off-by:

WANG Cong authored
struct tc_action is confusing, currently we use it for two purposes: 1) Pass in arguments and carry out results from helper functions 2) A generic representation for tc actions The first one is error-prone, since we need to make sure we don't miss anything. This patch aims to get rid of this use, by moving tc_action into tcf_common, so that they are allocated together in hashtable and can be cast'ed easily. And together with the following patch, we could really make tc_action a generic representation for all tc actions and each type of action can inherit from it.

Include the destination MAC address in the ntuple filter structure. The current code assumes that the destination MAC address is always the MAC address of the NIC. This may not be true if there are macvlans, for example. Add destination MAC address checking and configure the filter correctly using the correct index for the destination MAC address.

After a6127697 ("udp: prevent bugcheck if filter truncates packet too much"), there followed various other fixes for similar cases such as f4979fce ("rose: limit sk_filter trim to payload"). Latter introduced a new helper sk_filter_trim_cap(), where we can pass the trim limit directly to the socket filter handling. Make use of it here as well with sizeof(struct udphdr) as lower cap limit and drop the extra skb->len test in UDP's input path. Signed-off-by:

alloc_workqueue replaces deprecated create_singlethread_workqueue(). A dedicated workqueue has been used since the workitems are being used on a packet tx/rx path. Hence, WQ_MEM_RECLAIM has been set to guarantee forward progress under memory pressure. An ordered workqueue has been used since workitems &cfhsi->wake_up_work and &cfhsi->wake_down_work cannot be run concurrently. Calls to flush_workqueue() before destroy_workqueue() have been dropped since destroy_workqueue() itself calls drain_workqueue() which flushes repeatedly till the workqueue becomes empty.

Sargun Dhillon says: ==================== bpf: add bpf_probe_write_user helper & example This patch series contains two patches that add support for a probe_write helper to BPF programs. This allows them to manipulate user memory during the course of tracing. The second patch in the series has an example that uses it, in one the intended ways to divert execution. Thanks to Alexei Starovoitov, and Daniel Borkmann for being patient, review, and helping me get familiar with the code base. I've made changes based on their recommendations. This helper should be considered for experimental usage and debugging, so we print a warning to dmesg when it is along with the command and pid when someone tries to install a proglet that uses it. A follow-up patchset will contain a mechanism to verify the safety of the probe beyond what was done by hand. ---- v1->v2: restrict writing to user space, as opposed to globally v2->v3: Fixed formatting issues v3->v4: Rename copy_to_user -> bpf_probe_write Simplify checking of whether or not it's safe to write Add warnings to dmesg v4->v5: Raise warning level Cleanup location of warning code Make test fail when helper is broken v5->v6: General formatting cleanup Rename bpf_probe_write -> bpf_probe_write_user v6->v7: More formatting cleanup.

This example shows using a kprobe to act as a dnat mechanism to divert traffic for arbitrary endpoints. It rewrite the arguments to a syscall while they're still in userspace, and before the syscall has a chance to copy the argument into kernel space. Although this is an example, it also acts as a test because the mapped address is 255.255.255.255:555 -> real address, and that's not a legal address to connect to. If the helper is broken, the example will fail on the intermediate steps, as well as the final step to verify the rewrite of userspace memory succeeded. Signed-off-by:

This allows user memory to be written to during the course of a kprobe. It shouldn't be used to implement any kind of security mechanism because of TOC-TOU attacks, but rather to debug, divert, and manipulate execution of semi-cooperative processes. Although it uses probe_kernel_write, we limit the address space the probe can write into by checking the space with access_ok. We do this as opposed to calling copy_to_user directly, in order to avoid sleeping. In addition we ensure the threads's current fs / segment is USER_DS and the thread isn't exiting nor a kernel thread. Given this feature is meant for experiments, and it has a risk of crashing the system, and running programs, we print a warning on when a proglet that attempts to use this helper is installed, along with the pid and process name.

Such a big dump of register values is hardly useful on a production system. Another downside of the now removed functions is that calling emac_dump_regs resulted in at least 87 calls to dev_info while holding a spinlock and having irqs off which is a big source of latency. Signed-off-by:

Saeed Mahameed says: ==================== Mellanox 100G mlx5 minimum inline header mode This small series from Hadar adds the support for minimum inline header mode query in mlx5e NIC driver. Today on TX the driver copies to the HW descriptor only up to L2 header which is the default required mode and sufficient for today's needs. The header in the HW descriptor is used for HW loopback steering decision, without it packets will go directly to the wire with no questions asked. For TX loopback steering according to L2/L3/L4 headers, ConnectX-4 requires to copy the corresponding headers into the send queue(SQ) WQE HW descriptor so it can decide whether to loop it back or to forward to wire. For legacy E-Switch mode only L2 headers copy is required. For advanced steering (E-Switch offloads) more header layers may be required to be copied, the required mode will be advertised by FW to each VF and PF according to the corresponding E-Switch configuration.

Add support for query the minimum inline mode from the Firmware. It is required for correct TX steering according to L3/L4 packet headers. Each send queue (SQ) has inline mode that defines the minimal required headers that needs to be copied into the SQ WQE. The driver asks the Firmware for the wqe_inline_mode device capability value. In case the device capability defined as "vport context" the driver must check the reported min inline mode from the vport context before creating its SQs. Signed-off-by:

Jeff Kirsher says: ==================== 10GbE Intel Wired LAN Driver Updates 2016-07-22 This series contains updates to ixgbe and ixgbevf only. Emil fixes the NACK check in ixgbevf_set_uc_addr_vf() for instances where the index is not equal to zero. Fixes an issue where mac->ops.setup_fc can be NULL for backplanes which can cause the driver to crash on load. Don fixes the second parameter of the LED functions, which is the index to the LED we are interested in affecting. Fixed variable to store register reads to unsigned integer. Adds support for the new x553 hardware into ixgbevf. Fixed a missing rtnl lock around ixgbevf_reinit_locked(). Fixed an issue where in ixgbevf_reset_subtask() was not verifying that the port has been removed. Cleans up the initial crosstalk fix, since the SFP that indicates the presence of a SFP+ module changes between hardware types. Babu Moger fixes typo in freeing IRQ, since the array subscript increments after the execution of the statement. Wei Yongjun adds the missing destroy_workqueue() before returning from ixgbe_init_module() in the error handling case. Tony adds range checking for setting the MTU from the VF, where the PF can return a NACK but this was not passed on to the VF, so propagate the results from the PF to the VF so errors can be reported. Consolidates mailbox read and write functions, since the recent changes to ixgbevf_write_msg_read_ack(), other functions are performing the same operations done here. Colin Ian King removes a redundant check on ret_val, since ret_val has not changed since the previous check. ==================== Signed-off-by: -

The head skb for GSO packets won't travel through the inner depths of SCTP stack as it doesn't contain any chunks on it. That means skb->sk doesn't get set and then when sctp_recvmsg() calls sctp_inet6_skb_msgname() on the head_skb it panics, as this last needs to check flags at the socket (sp->v4mapped). The fix is to initialize skb->sk for th head skb once we are able to do it. That is, when the first chunk is processed. Signed-off-by:

Default kernel behavior is to delete IPv6 addresses on link down, which entails deletion of the multicast and the subnet-router anycast addresses. These deletions do not happen with sysctl setting to keep global IPv6 addresses on link down, so every link down/up causes an increment of the anycast and multicast refcounts. These bogus refcounts may stop these addrs from being removed on subsequent calls to delete them. The solution is to leave the groups for the multicast and subnet anycast on link down for the callflow when global IPv6 addresses are kept.

Merge tag 'wireless-drivers-next-for-davem-2016-07-22' of git://git.kernel.org/pub/scm/linux/kernel/git/kvalo/wireless-drivers-next Kalle Valo says: ==================== pull-request: wireless-drivers-next 2016-07-22 I'm sick so I have to keep this short, but here's the last pull request to net-next. This time there's a trivial conflict with mtd tree: http://lkml.kernel.org/g/20160720123133.44dab209@canb.auug.org.au We concluded with Brian (CCed) that it's best that we ask Linus to fix this. The patches have been in linux-next for a couple of days. This time I haven't done any merge tests so I don't know if there are any other conflicts etc. Please let me know if there are any problems. wireless-drivers-next patches for 4.8 Major changes: wl18xx * add initial mesh support bcma * serial flash support on non-MIPS SoCs ath10k * enable support for QCA9888 * disable wake_tx_queue() mac80211 op for older devices to workaround throughput regression ath9k * implement temperature compensation support for AR9003+ ==================== Signed-off-by:

Commit 486bdee0 ("sctp: add support for RPS and RFS") saves skb->hash into sk->sk_rxhash so that the inet_* can record it to flow table. But sctp uses sock_common_recvmsg as .recvmsg instead of inet_recvmsg, sock_common_recvmsg doesn't invoke sock_rps_record_flow to record the flow. It may cause that the receiver has no chances to record the flow if it doesn't send msg or poll the socket. So this patch fixes it by using inet_recvmsg as .recvmsg in sctp.

Davide Caratti says: ==================== macsec: fix configurable ICV length This series provides a fix for macsec configurable ICV length. The maximum length of ICV element has been made compliant to IEEE 802.1AE, and error reporting in case of cipher suite configuration failure has been improved. Finally, a test has been added to netlink verify() callback in order to avoid creation of macsec interfaces having user-provided ICV length values that are not supported by the cipher suite. ==================== Signed-off-by:

Test the cipher suite initialization in case ICV length has a value different than its default. If this test fails, creation of a new macsec link will also fail. This avoids situations where further security associations can't be added due to failures of crypto_aead_setauthsize(), caused by unsupported user-provided values of the ICV length. Signed-off-by:

IEEE 802.1AE-2006 standard recommends that the ICV element in a MACsec frame should not exceed 16 octets: add MACSEC_STD_ICV_LEN in uapi definitions accordingly, and avoid accepting configurations where the ICV length exceeds the standard value. Leave definition of MACSEC_MAX_ICV_LEN unchanged for backwards compatibility with userspace programs. Fixes: dece8d2b ("uapi: add MACsec bits") Signed-off-by:
