* bpf: rename sk_actions to align with bpf infrastructureJohn Fastabend2017-10-291-2/+2
| | | | | | | | | | | | | | | | | | | Recent additions to support multiple programs in cgroups impose a strict requirement, "all yes is yes, any no is no". To enforce this the infrastructure requires the 'no' return code, SK_DROP in this case, to be 0. To apply these rules to SK_SKB program types the sk_actions return codes need to be adjusted. This fix adds SK_PASS and makes 'SK_DROP = 0'. Finally, remove SK_ABORTED to remove any chance that the API may allow aborted program flows to be passed up the stack. This would be incorrect behavior and allow programs to break existing policies.

| * bpf: remove mark access for SK_SKB program typesJohn Fastabend2017-10-201-2/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The skb->mark field is a union with reserved_tailroom which is used in the TCP code paths from stream memory allocation. Allowing SK_SKB programs to set this field creates a conflict with future code optimizations, such as "gifting" the skb to the egress path instead of creating a new skb and doing a memcpy. Because we do not have a released version of SK_SKB yet lets just remove it for now. A more appropriate scratch pad to use at the socket layer is dev_scratch, but lets add that in future kernels when needed.

| * bpf: avoid preempt enable/disable in sockmap using tcp_skb_cb regionJohn Fastabend2017-10-203-4/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | SK_SKB BPF programs are run from the socket/tcp context but early in the stack before much of the TCP metadata is needed in tcp_skb_cb. So we can use some unused fields to place BPF metadata needed for SK_SKB programs when implementing the redirect function. This allows us to drop the preempt disable logic. It does however require an API change so sk_redirect_map() has been updated to additionally provide ctx_ptr to skb. Note, we do however continue to disable/enable preemption around actual BPF program running to account for map updates.

| * bpf: disallow arithmetic operations on context pointerJakub Kicinski2017-10-181-0/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit f1174f77b50c ("bpf/verifier: rework value tracking") removed the crafty selection of which pointer types are allowed to be modified. This is OK for most pointer types since adjust_ptr_min_max_vals() will catch operations on immutable pointers. One exception is PTR_TO_CTX which is now allowed to be offseted freely. The intent of aforementioned commit was to allow context access via modified registers. The offset passed to ->is_valid_access() verifier callback has been adjusted by the value of the variable offset. What is missing, however, is taking the variable offset into account when the context register is used. Or in terms of the code adding the offset to the value passed to the ->convert_ctx_access() callback. This leads to the following eBPF user code: r1 += 68 r0 = *(u32 *)(r1 + 8) exit being translated to this in kernel space: 0: (07) r1 += 68 1: (61) r0 = *(u32 *)(r1 +180) 2: (95) exit Offset 8 is corresponding to 180 in the kernel, but offset 76 is valid too. Verifier will "accept" access to offset 68+8=76 but then "convert" access to offset 8 as 180. Effective access to offset 248 is beyond the kernel context. (This is a __sk_buff example on a debug-heavy kernel - packet mark is 8 -> 180, 76 would be data.) Dereferencing the modified context pointer is not as easy as dereferencing other types, because we have to translate the access to reading a field in kernel structures which is usually at a different offset and often of a different size. To allow modifying the pointer we would have to make sure that given eBPF instruction will always access the same field or the fields accessed are "compatible" in terms of offset and size... Disallow dereferencing modified context pointers and add to selftests the test case described here.

| * | perf pmu: Unbreak perf record for arm/arm64 with events with explicit PMUMark Rutland2017-10-093-19/+47
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, perf record is broken on arm/arm64 systems when the PMU is specified explicitly as part of the event, e.g. $ ./perf record -e armv8_cortex_a53/cpu_cycles/u true In such cases, perf record fails to open events unless perf_event_paranoid is set to -1, even if the PMU in question supports mode exclusion. Further, even when perf_event_paranoid is toggled, no samples are recorded. This is an unintended side effect of commit: e3ba76deef23064f ("perf tools: Force uncore events to system wide monitoring) ... which assumes that if a PMU has an associated cpu_map, it is an uncore PMU, and forces events for such PMUs to be system-wide. This is not true for arm/arm64 systems, which can have heterogeneous CPUs. To account for this, multiple CPU PMUs are exposed, each with a "cpus" field under sysfs, which the perf tool parses into a cpu_map. ARM PMUs do not have a "cpumask" file, and only have a "cpus" file. For the gory details as to why, see commit: 7e3fcffe95544010 ("perf pmu: Support alternative sysfs cpumask") Given all of this, we can instead identify uncore PMUs by explicitly checking for a "cpumask" file, and restore arm/arm64 PMU support back to a working state. This patch does so, adding a new perf_pmu::is_uncore field, and splitting the existing cpumask parsing so that it can be reused.

This seems to fix it while still exercising -EEXIST in the background transfer once in a while. The fork child will quit after the last UFFDIO_COPY is run, so a repeated UFFDIO_COPY may not return -EEXIST. This change restricts the -EEXIST stress to the background transfer where the memory can't go away from under it. Also updated uffdio_zeropage, so the interface is consistent.

And the default call-graph parameter is 'graph,0.5,caller,function,percent'. Before this patch, 'perf report --call-graph' shows incorrect debug messages as below: # perf report --call-graph Invalid callchain mode: 0.5 Invalid callchain order: 0.5 Invalid callchain sort key: 0.5 Invalid callchain config key: 0.5 Invalid callchain mode: caller Invalid callchain mode: function Invalid callchain order: function Invalid callchain mode: percent Invalid callchain order: percent Invalid callchain sort key: percent That is because in function __parse_callchain_report_opt(),each field of the call-graph parameter is passed to parse_callchain_{mode,order, sort_key,value} in turn until it meets the matching value. For example, the order field "caller" is passed to parse_callchain_mode() firstly and obviously it doesn't match any mode field. Therefore parse_callchain_mode() will shows the debug message "Invalid callchain mode: caller", which could confuse users. The patch fixes this issue by moving the warning out of the function parse_callchain_{mode,order,sort_key,value}.

Testing it: As non root: $ sysctl kernel.perf_event_paranoid kernel.perf_event_paranoid = 2 $ perf record sleep 1 $ perf evlist -v cycles:uppp: ..., exclude_kernel: 1, ... precise_ip: 3, ... Now as non-root, but with kernel.perf_event_paranoid set set to the most permissive value, -1: $ sysctl kernel.perf_event_paranoid kernel.perf_event_paranoid = -1 $ perf record sleep 1 $ perf evlist -v cycles:ppp: ..., exclude_kernel: 0, ... precise_ip: 3, ... $ I.e. non-root, default kernel.perf_event_paranoid: :uppp modifier = not allowed to sample the kernel, non-root, most permissible kernel.perf_event_paranoid: :ppp = allowed to sample the kernel. In both cases, use the highest available precision: attr.precise_ip = 3.

| | | | | | | | | | | | | | | | | | | | | | | | | | | kselftest and kselftest-clean targets fail when object directory is specified to relocate objects. Main Makefile make O= path clears the built-in defines LINK.c, COMPILE.S, LINK.S, and RM that are used in lib.mk to build and clean targets. Define them.

| | | | | | | | | | | | | | | | | | | | | | | | | | | These self tests are just self contained binaries, they are not run by any of the scripts in the directory. This means they need to be marked with TEST_GEN_PROGS to actually be run, not TEST_GEN_FILES. Signed-off-by: Josef Bacik <jbacik@fb.com> Signed-off-by: Shuah Khan <shuahkh@osg.samsung.com>
