2019-02-14selftests: fix timestamping MakefileDeepa Dinamani
The clean target in the makefile conflicts with the generic kselftests lib.mk, and fails to properly remove the compiled test programs. Remove the redundant rule, the TEST_GEN_FILES will be already removed by the CLEAN macro in lib.mk.

2019-01-31bpf, selftests: fix handling of sparse CPU allocationsMartynas Pumputis
Previously, bpf_num_possible_cpus() had a bug when calculating a number of possible CPUs in the case of sparse CPU allocations, as it was considering only the first range or element of /sys/devices/system/cpu/possible. E.g. in the case of "0,2-3" (CPU 1 is not available), the function returned 1 instead of 3. This patch fixes the function by making it parse all CPU ranges and elements.

2019-01-25selftests/seccomp: Enhance per-arch ptrace syscall skip testsKees Cook
Passing EPERM during syscall skipping was confusing since the test wasn't actually exercising the errno evaluation -- it was just passing a literal "1" (EPERM). Instead, expand the tests to check both direct value returns (positive, 45000 in this case), and errno values (negative, -ESRCH in this case) to check both fake success and fake failure during syscall skipping.

The cpu-hotplug test assumes that we can offline the maximum CPU as described by /sys/devices/system/cpu/offline. However, in the case where the number of CPUs exceeds like kernel configuration then the offline count can be greater than the present count and we end up trying to test the offlining of a CPU that is not available to offline. Fix this by testing the maximum present CPU instead. Also, the test currently offlines the CPU and does not online it, so fix this by onlining the CPU after the test.

While running test_progs in a loop I found out that I'm sometimes hitting "Didn't find expected build ID from the map" error. Looking at stack_map_get_build_id_offset() it seems that it is racy (by design) and can sometimes return BPF_STACK_BUILD_ID_IP (i.e. can't trylock current->mm->mmap_sem). Let's retry this test a single time.

2019-01-16selftests: tc-testing: fix parsing of ife typeDavide Caratti
In iproute2 commit 90c5c969f0b9 ("fix print_0xhex on 32 bit"), the format specifier for the ife type changed from 0x%X to %#llX, causing systematic failures in the following TDC test cases: 7682 - Create valid ife encode action with mark and pass control ef47 - Create valid ife encode action with mark and pipe control df43 - Create valid ife encode action with mark and continue control e4cf - Create valid ife encode action with mark and drop control ccba - Create valid ife encode action with mark and reclassify control a1cf - Create valid ife encode action with mark and jump control cb3d - Create valid ife encode action with mark value at 32-bit maximum 95ed - Create valid ife encode action with prio and pass control aa17 - Create valid ife encode action with prio and pipe control 74c7 - Create valid ife encode action with prio and continue control 7a97 - Create valid ife encode action with prio and drop control f66b - Create valid ife encode action with prio and reclassify control 3056 - Create valid ife encode action with prio and jump control 7dd3 - Create valid ife encode action with prio value at 32-bit maximum 05bb - Create valid ife encode action with tcindex and pass control ce65 - Create valid ife encode action with tcindex and pipe control 09cd - Create valid ife encode action with tcindex and continue control 8eb5 - Create valid ife encode action with tcindex and continue control 451a - Create valid ife encode action with tcindex and drop control d76c - Create valid ife encode action with tcindex and reclassify control e731 - Create valid ife encode action with tcindex and jump control b7b8 - Create valid ife encode action with tcindex value at 16-bit maximum 2a9c - Create valid ife encode action with mac src parameter cf5c - Create valid ife encode action with mac dst parameter 2353 - Create valid ife encode action with mac src and mac dst parameters 552c - Create valid ife encode action with mark and type parameters 0421 - Create valid ife encode action with prio and type parameters 4017 - Create valid ife encode action with tcindex and type parameters fac3 - Create valid ife encode action with index at 32-bit maximnum 7c25 - Create valid ife decode action with pass control dccb - Create valid ife decode action with pipe control 7bb9 - Create valid ife decode action with continue control d9ad - Create valid ife decode action with drop control 219f - Create valid ife decode action with reclassify control 8f44 - Create valid ife decode action with jump control b330 - Create ife encode action with cookie Change 'matchPattern' values, allowing '0' and '0x0' if ife type is equal to 0, and accepting both '0x' and '0X' otherwise, to let these tests pass both with old and new tc binaries.

2019-01-15x86/selftests/pkeys: Fork() to check for state being preservedDave Hansen
There was a bug where the per-mm pkey state was not being preserved across fork() in the child. fork() is performed in the pkey selftests, but all of the pkey activity is performed in the parent. The child does not perform any actions sensitive to pkey state. To make the test more sensitive to these kinds of bugs, add a fork() where the parent exits, and execution continues in the child. To achieve this let the key exhaustion test not terminate at the first allocation failure and fork after 2*NR_PKEYS loops and continue in the child.

2019-01-09xfrm: policy: fix infinite loop when merging src-nodesFlorian Westphal
With very small change to test script we can trigger softlockup due to bogus assignment of 'p' (policy to be examined) on restart. Previously the two to-be-merged nodes had same address/prefixlength pair, so no erase/reinsert was necessary, we only had to append the list from node a to b. If prefix lengths are different, the node has to be deleted and re-inserted into the tree, with the updated prefix length. This was broken; due to bogus update to 'p' this loops forever. Add a 'restart' label and use that instead. While at it, don't perform the unneeded reinserts of the policies that are already sorted into the 'new' node. A previous patch in this series made xfrm_policy_inexact_list_reinsert() use the relative position indicator to sort policies according to age in case priorities are identical.

The existing script lacks a policy pattern that triggers 'tree node merges' in the kernel. Consider adding policy affecting following subnet: pol1: dst 10.0.0.0/22 pol2: dst 10.0.0.0/23 # adds to existing 10.0.0.0/22 node -> no problems here. But now, lets consider reverse order: pol1: dst 10.0.0.0/24 pol2: dst 10.0.0.0/23 # CANNOT add to existing node When second policy gets added, the kernel must check that the new node ("10.0.0.0/23") doesn't overlap with any existing subnet. Example: dst 10.0.0.0/24 dst 10.0.0.1/24 dst 10.0.0.0/23 When the third policy gets added, the kernel must replace the nodes for the 10.0.0.0/24 and 10.0.0.1/24 policies with a single one and must merge all the subtrees/lists stored in those nodes into the new node. The existing test cases only have overlaps with a single node, so no merging takes place (we can always remove the 'old' node and replace it with the new subnet prefix). Add a few 'block policies' in a pattern that triggers this, with a priority that will make kernel prefer the 'esp' rules. Make sure the 'tunnel ping' tests still pass after they have been added.
