2018-03-30bpf: sockmap redirect ingress supportJohn Fastabend
Add support for the BPF_F_INGRESS flag in sk_msg redirect helper. To do this add a scatterlist ring for receiving socks to check before calling into regular recvmsg call path. Additionally, because the poll wakeup logic only checked the skb recv queue we need to add a hook in TCP stack (similar to write side) so that we have a way to wake up polling socks when a scatterlist is redirected to that sock. After this all that is needed is for the redirect helper to push the scatterlist into the psock receive queue.

From Tariq: (RX updates) - Disable Striding RQ when PCI devices, striding RQ limits the use of CQE compression feature, which is very critical for slow PCI devices performance, in this change we will prefer CQE compression over Striding RQ only on specific "slow" PCIe links. - RX path cleanups - Private flag to enable/disable striding RQ From Eran: (TX fast recovery) - TX timeout logic improvements, fast SQ recovery and TX error reporting if a HW error occurs while transmitting on a specific SQ, the driver will ignore such error and will wait for TX timeout to occur and reset all the rings. Instead, the current series improves the resiliency for such HW errors by detecting TX completions with errors, which will report them and perform a fast recover for the specific faulty SQ even before a TX timeout is detected. ==================== Signed-off-by: David S.

2018-03-29net: Introduce net_rwsem to protect net_namespace_listKirill Tkhai
rtnl_lock() is used everywhere, and contention is very high. When someone wants to iterate over alive net namespaces, he/she has no a possibility to do that without exclusive lock. But the exclusive rtnl_lock() in such places is overkill, and it just increases the contention. Yes, there is already for_each_net_rcu() in kernel, but it requires rcu_read_lock(), and this can't be sleepable. Also, sometimes it may be need really prevent net_namespace_list growth, so for_each_net_rcu() is not fit there. This patch introduces new rw_semaphore, which will be used instead of rtnl_mutex to protect net_namespace_list. It is sleepable and allows not-exclusive iterations over net namespaces list. It allows to stop using rtnl_lock() in several places (what is made in next patches) and makes less the time, we keep rtnl_mutex. Here we just add new lock, while the explanation of we can remove rtnl_lock() there are in next patches. Fine grained locks generally are better, then one big lock, so let's do that with net_namespace_list, while the situation allows that.

2018-03-29perf/x86/pt, coresight: Clean up address filter structureAlexander Shishkin
This is a cosmetic patch that deals with the address filter structure's ambiguous fields 'filter' and 'range'. The former stands to mean that the filter's *action* should be to filter the traces to its address range if it's set or stop tracing if it's unset. This is confusing and hard on the eyes, so this patch replaces it with 'action' enum. The 'range' field is completely redundant (meaning that the filter is an address range as opposed to a single address trigger), as we can use zero size to mean the same thing.

2018-03-28bpf: introduce BPF_RAW_TRACEPOINTAlexei Starovoitov
Introduce BPF_PROG_TYPE_RAW_TRACEPOINT bpf program type to access kernel internal arguments of the tracepoints in their raw form. >From bpf program point of view the access to the arguments look like: struct bpf_raw_tracepoint_args { __u64 args[0]; }; int bpf_prog(struct bpf_raw_tracepoint_args *ctx) { // program can read args[N] where N depends on tracepoint // and statically verified at program load+attach time } kprobe+bpf infrastructure allows programs access function arguments. This feature allows programs access raw tracepoint arguments. Similar to proposed 'dynamic ftrace events' there are no abi guarantees to what the tracepoints arguments are and what their meaning is. The program needs to type cast args properly and use bpf_probe_read() helper to access struct fields when argument is a pointer. For every tracepoint __bpf_trace_##call function is prepared. In assembler it looks like: (gdb) disassemble __bpf_trace_xdp_exception Dump of assembler code for function __bpf_trace_xdp_exception: 0xffffffff81132080 <+0>: mov %ecx,%ecx 0xffffffff81132082 <+2>: jmpq 0xffffffff811231f0 <bpf_trace_run3> where TRACE_EVENT(xdp_exception, TP_PROTO(const struct net_device *dev, const struct bpf_prog *xdp, u32 act), The above assembler snippet is casting 32-bit 'act' field into 'u64' to pass into bpf_trace_run3(), while 'dev' and 'xdp' args are passed as-is. All of ~500 of __bpf_trace_*() functions are only 5-10 byte long and in total this approach adds 7k bytes to .text. This approach gives the lowest possible overhead while calling trace_xdp_exception() from kernel C code and transitioning into bpf land. Since tracepoint+bpf are used at speeds of 1M+ events per second this is valuable optimization. The new BPF_RAW_TRACEPOINT_OPEN sys_bpf command is introduced that returns anon_inode FD of 'bpf-raw-tracepoint' object. The user space looks like: // load bpf prog with BPF_PROG_TYPE_RAW_TRACEPOINT type prog_fd = bpf_prog_load(...); // receive anon_inode fd for given bpf_raw_tracepoint with prog attached raw_tp_fd = bpf_raw_tracepoint_open("xdp_exception", prog_fd); Ctrl-C of tracing daemon or cmdline tool that uses this feature will automatically detach bpf program, unload it and unregister tracepoint probe. On the kernel side the __bpf_raw_tp_map section of pointers to tracepoint definition and to __bpf_trace_*() probe function is used to find a tracepoint with "xdp_exception" name and corresponding __bpf_trace_xdp_exception() probe function which are passed to tracepoint_probe_register() to connect probe with tracepoint. Addition of bpf_raw_tracepoint doesn't interfere with ftrace and perf tracepoint mechanisms. perf_event_open() can be used in parallel on the same tracepoint. Multiple bpf_raw_tracepoint_open("xdp_exception", prog_fd) are permitted. Each with its own bpf program. The kernel will execute all tracepoint probes and all attached bpf programs. In the future bpf_raw_tracepoints can be extended with query/introspection logic. __bpf_raw_tp_map section logic was contributed by Steven Rostedt Signed-off-by: Alexei Starovoitov <ast@kernel.org> Signed-off-by: Steven Rostedt (VMware) <rostedt@goodmis.org> Acked-by: Steven Rostedt (VMware) <rostedt@goodmis.org> Signed-off-by: Daniel Borkmann <daniel@iogearbox.net>

Commit 7af1bb19f1d7 ("reset: add support for non-DT systems") introduced reset control lookup mechanism for boards that still use board files. The routine used to register lookup entries takes the corresponding reset_controlled_dev structure as argument. It's been determined however that for the first user of this new interface - davinci psc driver - it will be easier to register the lookup entries using the reset controller device name. This patch changes the way lookup entries are added.

2018-03-27reset: add support for non-DT systemsBartosz Golaszewski
The reset framework only supports device-tree. There are some platforms however, which need to use it even in legacy, board-file based mode. An example of such architecture is the DaVinci family of SoCs which supports both device tree and legacy boot modes and we don't want to introduce any regressions. We're currently working on converting the platform from its hand-crafted clock API to using the common clock framework. Part of the overhaul will be representing the chip's power sleep controller's reset lines using the reset framework. This changeset extends the core reset code with a new reset lookup entry structure. It contains data allowing the reset core to associate reset lines with devices by comparing the dev_id and con_id strings. It also provides a function allowing drivers to register lookup entries with the framework. The new lookup function is only called as a fallback in case the of_node field is NULL and doesn't change anything for current users. Tested with a dummy reset driver with several lookup entries.

In order to properly support compatibility strings as described in the bindings/mtd/partition.txt "ofpart" type should be treated as an indication for looking into OF. MTD should check "compatible" property and search for a matching parser rather than blindly trying the one supporting "fixed-partitions". It also means that existing "fixed-partitions" parser should get renamed to use a more meaningful name. This commit achievies that aim by introducing a new mtd_part_of_parse(). It works by looking for a matching parser for every string in the "compatibility" property (starting with the most specific one). Please note that driver-specified parsers still take a precedence. It's assumed that driver providing a parser type has a good reason for that (e.g. having platform data with device-specific info). Also doing otherwise could break existing setups. The same applies to using default parsers (including "cmdlinepart") as some overwrite DT data with cmdline argument. Partition parsers can now provide an of_match_table to enable flash<-->parser matching via device tree as documented in the mtd/partition.txt. This support is currently limited to built-in parsers as it uses request_module() and friends. This should be sufficient for most cases though as compiling parsers as modules isn't a common choice.

2018-03-26net/mlx5: Add packet dropped while vport down statisticsMoshe Shemesh
Added the following packets dropped while vport down statistics: Rx dropped while vport down - counts packets which were steered by e-switch to a vport, but dropped since the vport was down. This counter will be shown on ip link tool as part of the vport rx_dropped counter. Tx dropped while vport down - counts packets which were transmitted by a vport, but dropped due to vport logical link down. This counter will be shown on ip link tool as part of the vport tx_dropped counter. The counters are read from FW by command QUERY_VNIC_ENV.
