2018-01-12error-injection: Add injectable error typesMasami Hiramatsu7-15/+66
Add injectable error types for each error-injectable function. One motivation of error injection test is to find software flaws, mistakes or mis-handlings of expectable errors. If we find such flaws by the test, that is a program bug, so we need to fix it. But if the tester miss input the error (e.g. just return success code without processing anything), it causes unexpected behavior even if the caller is correctly programmed to handle any errors. That is not what we want to test by error injection. To clarify what type of errors the caller must expect for each injectable function, this introduces injectable error types: - EI_ETYPE_NULL : means the function will return NULL if it fails. No ERR_PTR, just a NULL. - EI_ETYPE_ERRNO : means the function will return -ERRNO if it fails. - EI_ETYPE_ERRNO_NULL : means the function will return -ERRNO (ERR_PTR) or NULL. ALLOW_ERROR_INJECTION() macro is expanded to get one of NULL, ERRNO, ERRNO_NULL to record the error type for each function. e.g. ALLOW_ERROR_INJECTION(open_ctree, ERRNO) This error types are shown in debugfs as below. ==== / # cat /sys/kernel/debug/error_injection/list open_ctree [btrfs] ERRNO io_ctl_init [btrfs] ERRNO ==== Signed-off-by: Masami Hiramatsu <mhiramat@kernel.org> Reviewed-by: Josef Bacik <jbacik@fb.com> Signed-off-by: Alexei Starovoitov <ast@kernel.org>
2018-01-12error-injection: Separate error-injection from kprobeMasami Hiramatsu22-213/+317
Since error-injection framework is not limited to be used by kprobes, nor bpf. Other kernel subsystems can use it freely for checking safeness of error-injection, e.g. livepatch, ftrace etc. So this separate error-injection framework from kprobes. Some differences has been made: - "kprobe" word is removed from any APIs/structures. - BPF_ALLOW_ERROR_INJECTION() is renamed to ALLOW_ERROR_INJECTION() since it is not limited for BPF too. - CONFIG_FUNCTION_ERROR_INJECTION is the config item of this feature. It is automatically enabled if the arch supports error injection feature for kprobe or ftrace etc. Signed-off-by: Masami Hiramatsu <mhiramat@kernel.org> Reviewed-by: Josef Bacik <jbacik@fb.com> Signed-off-by: Alexei Starovoitov <ast@kernel.org>

2018-01-12tracing/kprobe: bpf: Check error injectable event is on function entryMasami Hiramatsu7-32/+31
Check whether error injectable event is on function entry or not. Currently it checks the event is ftrace-based kprobes or not, but that is wrong. It should check if the event is on the entry of target function. Since error injection will override a function to just return with modified return value, that operation must be done before the target function starts making stackframe. As a side effect, bpf error injection is no need to depend on function-tracer. It can work with sw-breakpoint based kprobe events too.

2018-01-11samples/bpf: xdp2skb_meta shows transferring info from XDP to SKBJesper Dangaard Brouer3-0/+324
Creating a bpf sample that shows howto use the XDP 'data_meta' infrastructure, created by Daniel Borkmann. Very few drivers support this feature, but I wanted a functional sample to begin with, when working on adding driver support. XDP data_meta is about creating a communication channel between BPF programs. This can be XDP tail-progs, but also other SKB based BPF hooks, like in this case the TC clsact hook. In this sample I show that XDP can store info named "mark", and TC/clsact chooses to use this info and store it into the skb->mark. It is a bit annoying that XDP and TC samples uses different tools/libs when attaching their BPF hooks. As the XDP and TC programs need to cooperate and agree on a struct-layout, it is best/easiest if the two programs can be contained within the same BPF restricted-C file. As the bpf-loader, I choose to not use bpf_load.c (or libbpf), but instead wrote a bash shell scripted named xdp2skb_meta.sh, which demonstrate howto use the iproute cmdline tools 'tc' and 'ip' for loading BPF programs. To make it easy for first time users, the shell script have command line parsing, and support --verbose and --dry-run mode, if you just want to see/learn the tc+ip command syntax: # ./xdp2skb_meta.sh --dev ixgbe2 --dry-run # Dry-run mode: enable VERBOSE and don't call TC+IP tc qdisc del dev ixgbe2 clsact tc qdisc add dev ixgbe2 clsact tc filter add dev ixgbe2 ingress prio 1 handle 1 bpf da obj ./xdp2skb_meta_kern.o sec tc_mark # Flush XDP on device: ixgbe2 ip link set dev ixgbe2 xdp off ip link set dev ixgbe2 xdp obj ./xdp2skb_meta_kern.o sec xdp_mark Signed-off-by: Jesper Dangaard Brouer <brouer@redhat.com> Signed-off-by: Daniel Borkmann <daniel@iogearbox.net>

2018-01-10mlxsw: pci: Wait after reset before accessing HWYuval Mintz2-1/+7
After performing reset driver polls on HW indication until learning that the reset is done, but immediately after reset the device becomes unresponsive which might lead to completion timeout on the first read. Wait for 100ms before starting the polling.

2018-01-10nfp: always unmask aux interrupts at initJakub Kicinski1-0/+2
The link state and exception interrupts may be masked when we probe. The firmware should in theory prevent sending (and automasking) those interrupts if the device is disabled, but if my reading of the FW code is correct there are firmwares out there with race conditions in this area. The interrupt may also be masked if previous driver which used the device was malfunctioning and we didn't load the FW (there is no other good way to comprehensively reset the PF). Note that FW unmasks the data interrupts by itself when vNIC is enabled, such helpful operation is not performed for LSC/EXN interrupts. Always unmask the auxiliary interrupts after request_irq(). On the remove path add missing PCI write flush before free_irq().
