2018-01-15net: phy: remove parameter new_link from phy_mac_interrupt()Heiner Kallweit1-3/+4
I see two issues with parameter new_link: 1. It's not needed. See also phy_interrupt(), works w/o this parameter. phy_mac_interrupt sets the state to PHY_CHANGELINK and triggers the state machine which then calls phy_read_status. And phy_read_status updates the link state. 2. phy_mac_interrupt is used in interrupt context and getting the link state may sleep (at least when having to access the PHY registers via MDIO bus). So let's remove it.

2018-01-08bnxt_en: Fix the 'Invalid VF' id check in bnxt_vf_ndo_prep routine.Venkat Duvvuru1-1/+1
In bnxt_vf_ndo_prep (which is called by bnxt_get_vf_config ndo), there is a check for "Invalid VF id". Currently, the check is done against max_vfs. However, the user doesn't always create max_vfs. So, the check should be against the created number of VFs. The number of bnxt_vf_info structures that are allocated in bnxt_alloc_vf_resources routine is the "number of requested VFs". So, if an "invalid VF id" falls between the requested number of VFs and the max_vfs, the driver will be dereferencing an invalid pointer.

Daniel Borkmann says: ==================== pull-request: bpf-next 2018-01-07 The following pull-request contains BPF updates for your *net-next* tree. The main changes are: 1) Add a start of a framework for extending struct xdp_buff without having the overhead of populating every data at runtime. Idea is to have a new per-queue struct xdp_rxq_info that holds read mostly data (currently that is, queue number and a pointer to the corresponding netdev) which is set up during rxqueue config time. When a XDP program is invoked, struct xdp_buff holds a pointer to struct xdp_rxq_info that the BPF program can then walk. The user facing BPF program that uses struct xdp_md for context can use these members directly, and the verifier rewrites context access transparently by walking the xdp_rxq_info and net_device pointers to load the data, from Jesper. 2) Redo the reporting of offload device information to user space such that it works in combination with network namespaces. The latter is reported through a device/inode tuple as similarly done in other subsystems as well (e.g. perf) in order to identify the namespace. For this to work, ns_get_path() has been generalized such that the namespace can be retrieved not only from a specific task (perf case), but also from a callback where we deduce the netns (ns_common) from a netdevice. bpftool support using the new uapi info and extensive test cases for test_offload.py in BPF selftests have been added as well, from Jakub. 3) Add two bpftool improvements: i) properly report the bpftool version such that it corresponds to the version from the kernel source tree. So pick the right linux/version.h from the source tree instead of the installed one. ii) fix bpftool and also bpf_jit_disasm build with bintutils >= 2.9. The reason for the build breakage is that binutils library changed the function signature to select the disassembler. Given this is needed in multiple tools, add a proper feature detection to the tools/build/features infrastructure, from Roman. 4) Implement the BPF syscall command BPF_MAP_GET_NEXT_KEY for the stacktrace map. It is currently unimplemented, but there are use cases where user space needs to walk all stacktrace map entries e.g. for dumping or deleting map entries w/o having to close and recreate the map. Add BPF selftests along with it, from Yonghong. 5) Few follow-up cleanups for the bpftool cgroup code: i) rename the cgroup 'list' command into 'show' as we have it for other subcommands as well, ii) then alias the 'show' command such that 'list' is accepted which is also common practice in iproute2, and iii) remove couple of newlines from error messages using p_err(), from Jakub. 6) Two follow-up cleanups to sockmap code: i) remove the unused bpf_compute_data_end_sk_skb() function and ii) only build the sockmap infrastructure when CONFIG_INET is enabled since it's only aware of TCP sockets at this time, from John. ==================== Signed-off-by: David S.

2017-12-27bnx2x: Improve reliability in case of nested PCI errorsGuilherme G. Piccoli2-3/+15
While in recovery process of PCI error (called EEH on PowerPC arch), another PCI transaction could be corrupted causing a situation of nested PCI errors. Also, this scenario could be reproduced with error injection mechanisms (for debug purposes). We observe that in case of nested PCI errors, bnx2x might attempt to initialize its shmem and cause a kernel crash due to bad addresses read from MCP. Multiple different stack traces were observed depending on the point the second PCI error happens. This patch avoids the crashes by: * failing PCI recovery in case of nested errors (since multiple PCI errors in a row are not expected to lead to a functional adapter anyway), and by, * preventing access to adapter FW when MCP is failed (we mark it as failed when shmem cannot get initialized properly).

2017-12-11rhashtable: Change rhashtable_walk_start to return voidTom Herbert1-5/+1
Most callers of rhashtable_walk_start don't care about a resize event which is indicated by a return value of -EAGAIN. So calls to rhashtable_walk_start are wrapped wih code to ignore -EAGAIN. Something like this is common: ret = rhashtable_walk_start(rhiter); if (ret && ret != -EAGAIN) goto out; Since zero and -EAGAIN are the only possible return values from the function this check is pointless. The condition never evaluates to true. This patch changes rhashtable_walk_start to return void. This simplifies code for the callers that ignore -EAGAIN. For the few cases where the caller cares about the resize event, particularly where the table can be walked in mulitple parts for netlink or seq file dump, the function rhashtable_walk_start_check has been added that returns -EAGAIN on a resize event.

The main changes are: 1) Addition of a software model for BPF offloads in order to ease testing code changes in that area and make semantics more clear. This is implemented in a new driver called netdevsim, which can later also be extended for other offloads. SR-IOV support is added as well to netdevsim. BPF kernel selftests for offloading are added so we can track basic functionality as well as exercising all corner cases around BPF offloading, from Jakub. 2) Today drivers have to drop the reference on BPF progs they hold due to XDP on device teardown themselves. Change this in order to make XDP handling inside the drivers less error prone, and move disabling XDP to the core instead, also from Jakub. 3) Misc set of BPF verifier improvements and cleanups as preparatory work for upcoming BPF-to-BPF calls. Among others, this set also improves liveness marking such that pruning can be slightly more effective. Register and stack liveness information is now included in the verifier log as well, from Alexei. 4) nfp JIT improvements in order to identify load/store sequences in the BPF prog e.g. coming from memcpy lowering and optimizing them through the NPU's command push pull (CPP) instruction, from Jiong. 5) Cleanups to test_cgrp2_attach2.c BPF sample code in oder to remove bpf_prog_attach() magic values and replacing them with actual proper attach flag instead, from David. ==================== Signed-off-by: David S.

2017-12-02bnxt_en: Need to unconditionally shut down RoCE in bnxt_shutdownRay Jui1-1/+2
The current 'bnxt_shutdown' implementation only invokes 'bnxt_ulp_shutdown' to shut down RoCE in the case when the system is in the path of power off (SYSTEM_POWER_OFF). While this may work in most cases, it does not work in the smart NIC case, when Linux 'reboot' command is initiated from the Linux that runs on the ARM cores of the NIC card. In this particular case, Linux 'reboot' results in a system 'L3' level reset where the entire ARM and associated subsystems are being reset, but at the same time, Nitro core is being kept in sane state (to allow external PCIe connected servers to continue to work). Without properly shutting down RoCE and freeing all associated resources, it results in the ARM core to hang immediately after the 'reboot' By always invoking 'bnxt_ulp_shutdown' in 'bnxt_shutdown', it fixes the above issue Fixes: 0efd2fc65c92 ("bnxt_en: Add a callback to inform RDMA driver during PCI shutdown.")

2017-12-03net: xdp: make the stack take care of the tear downJakub Kicinski1-2/+0
Since day one of XDP drivers had to remember to free the program on the remove path. This leads to code duplication and is error prone. Make the stack query the installed programs on unregister and if something is installed, remove the program. Freeing of program attached to XDP generic is moved from free_netdev() as well. Because the remove will now be called before notifiers are invoked, BPF offload state of the program will not get destroyed before uninstall.

2017-11-21treewide: setup_timer() -> timer_setup()Kees Cook5-15/+15
This converts all remaining cases of the old setup_timer() API into using timer_setup(), where the callback argument is the structure already holding the struct timer_list. These should have no behavioral changes, since they just change which pointer is passed into the callback with the same available pointers after conversion. It handles the following examples, in addition to some other variations. Casting from unsigned long: void my_callback(unsigned long data) { struct something *ptr = (struct something *)data; ... } ... setup_timer(&ptr->my_timer, my_callback, ptr); and forced object casts: void my_callback(struct something *ptr) { ... } ... setup_timer(&ptr->my_timer, my_callback, (unsigned long)ptr); become: void my_callback(struct timer_list *t) { struct something *ptr = from_timer(ptr, t, my_timer); ... } ... timer_setup(&ptr->my_timer, my_callback, 0); Direct function assignments: void my_callback(unsigned long data) { struct something *ptr = (struct something *)data; ... } ... ptr->my_timer.function = my_callback; have a temporary cast added, along with converting the args: void my_callback(struct timer_list *t) { struct something *ptr = from_timer(ptr, t, my_timer); ... } ... ptr->my_timer.function = (TIMER_FUNC_TYPE)my_callback; And finally, callbacks without a data assignment: void my_callback(unsigned long data) { ... } ... setup_timer(&ptr->my_timer, my_callback, 0); have their argument renamed to verify they're unused during conversion: void my_callback(struct timer_list *unused) { ... } ... timer_setup(&ptr->my_timer, my_callback, 0); The conversion is done with the following Coccinelle script: spatch --very-quiet --all-includes --include-headers \ -I ./arch/x86/include -I ./arch/x86/include/generated \ -I ./include -I ./arch/x86/include/uapi \ -I ./arch/x86/include/generated/uapi -I ./include/uapi \ -I ./include/generated/uapi --include ./include/linux/kconfig.h \ --dir . \ --cocci-file ~/src/data/timer_setup.cocci @fix_address_of@ expression e;

2017-11-14bnx2x: fix slowpath null crashZhu Yanjun1-3/+10
When "NETDEV WATCHDOG: em4 (bnx2x): transmit queue 2 timed out" occurs, BNX2X_SP_RTNL_TX_TIMEOUT is set. In the function bnx2x_sp_rtnl_task, bnx2x_nic_unload and bnx2x_nic_load are executed to shutdown and open NIC. In the function bnx2x_nic_load, bnx2x_alloc_mem allocates dma failure. The message "bnx2x: [bnx2x_alloc_mem:8399(em4)]Can't allocate memory" pops out. The variable slowpath is set to NULL. When shutdown the NIC, the function bnx2x_nic_unload is called. In the function bnx2x_nic_unload, the following functions are executed. bnx2x_chip_cleanup bnx2x_set_storm_rx_mode bnx2x_set_q_rx_mode bnx2x_set_q_rx_mode bnx2x_config_rx_mode bnx2x_set_rx_mode_e2 In the function bnx2x_set_rx_mode_e2, the variable slowpath is operated. Then the crash occurs. To fix this crash, the variable slowpath is checked. And in the function bnx2x_sp_rtnl_task, after dma memory allocation fails, another shutdown and open NIC is executed.
