2020-11-06bpf: Fix tests for local_storageKP Singh1-9/+15
The {inode,sk}_storage_result checking if the correct value was retrieved was being clobbered unconditionally by the return value of the bpf_{inode,sk}_storage_delete call. Also, consistently use the newly added BPF_LOCAL_STORAGE_GET_F_CREATE flag.

2020-11-05bpf: Lift hashtab key_size limitFlorian Lehner3-1/+89
Currently key_size of hashtab is limited to MAX_BPF_STACK. As the key of hashtab can also be a value from a per cpu map it can be larger than MAX_BPF_STACK. The use-case for this patch originates to implement allow/disallow lists for files and file paths. The maximum length of file paths is defined by PATH_MAX with 4096 chars including nul. This limit exceeds MAX_BPF_STACK.

2020-11-05bpf: Zero-fill re-used per-cpu map elementDavid Verbeiren2-0/+247
Zero-fill element values for all other cpus than current, just as when not using prealloc. This is the only way the bpf program can ensure known initial values for all cpus ('onallcpus' cannot be set when coming from the bpf program). The scenario is: bpf program inserts some elements in a per-cpu map, then deletes some (or userspace does). When later adding new elements using bpf_map_update_elem(), the bpf program can only set the value of the new elements for the current cpu. When prealloc is enabled, previously deleted elements are re-used. Without the fix, values for other cpus remain whatever they were when the re-used entry was previously freed. A selftest is added to validate correct operation in above scenario as well as in case of LRU per-cpu map element re-use.

2020-11-05selftest/bpf: Relax btf_dedup test checksAndrii Nakryiko1-15/+25
Remove the requirement of a strictly exact string section contents. This used to be true when string deduplication was done through sorting, but with string dedup done through hash table, it's no longer true. So relax test harness to relax strings checks and, consequently, type checks, which now don't have to have exactly the same string offsets.

2020-11-04selftests: mptcp: add ADD_ADDR timeout test caseGeliang Tang2-24/+80
This patch added the test case for retransmitting ADD_ADDR when timeout occurs. It set NS1's add_addr_timeout to 1 second, and drop NS2's ADD_ADDR echo packets. Here we need to slow down the transfer process of all data to let the ADD_ADDR suboptions can be retransmitted three times. So we added a new parameter "speed" for do_transfer, it can be set with fast or slow. We also added three new optional parameters for run_tests, and dropped run_remove_tests function. Since we added the netfilter rules in this test case, we need to update the "config" file.

2020-11-03selftests/bpf: Replace EXPECT_EQ with ASSERT_EQ and refactor verify_resultsAlexander Duyck1-72/+43
There is already logic in test_progs.h for asserting that a value is expected to be another value. So instead of reinventing it we should just make use of ASSERT_EQ in tcpbpf_user.c. This will allow for better debugging and integrates much more closely with the test_progs framework. In addition we can refactor the code a bit to merge together the two verify functions and tie them together into a single function. Doing this helps to clean the code up a bit and makes it more readable as all the verification is now done in one function. Lastly we can relocate the verification to the end of the run_test since it is logically part of the test itself. With this we can drop the need for a return value from run_test since verification becomes the last step of the call and then immediately following is the tear down of the test setup.

2020-11-03selftests/bpf: Drop python client/server in favor of threadsAlexander Duyck3-147/+78
Drop the tcp_client/server.py files in favor of using a client and server thread within the test case. Specifically we spawn a new thread to play the role of the server, and the main testing thread plays the role of client. Add logic to the end of the run_test function to guarantee that the sockets are closed when we begin verifying results. Doing this we are able to reduce overhead since we don't have two python workers possibly floating around. In addition we don't have to worry about synchronization issues and as such the retry loop waiting for the threads to close the sockets can be dropped as we will have already closed the sockets in the local executable and synchronized the server thread.

2020-11-03selftests/bpf: Move test_tcppbf_user into test_progsAlexander Duyck3-36/+10
Recently a bug was missed due to the fact that test_tcpbpf_user is not a part of test_progs. In order to prevent similar issues in the future move the test functionality into test_progs. By doing this we can make certain that it is a part of standard testing and will not be overlooked. As a part of moving the functionality into test_progs it is necessary to integrate with the test_progs framework and to drop any redundant code. This patch: 1. Cleans up the include headers 2. Dropped a duplicate definition of bpf_find_map 3. Switched over to using test_progs specific cgroup functions 4. Renamed main to test_tcpbpf_user 5. Dropped return value in favor of CHECK_FAIL to check for errors The general idea is that I wanted to keep the changes as small as possible while moving the file into the test_progs framework. The follow-on patches are meant to clean up the remaining issues such as the use of CHECK_FAIL.

Unless we want to test with THP, then we shouldn't require it to be configured by the host kernel. Unfortunately, even advising with MADV_NOHUGEPAGE does require it, so check for THP first in order to avoid madvise failing with EINVAL.

2020-10-31KVM: selftests: test behavior of unmapped L2 APIC-access addressJim Mattson5-0/+159
Add a regression test for commit 671ddc700fd0 ("KVM: nVMX: Don't leak L1 MMIO regions to L2"). First, check to see that an L2 guest can be launched with a valid APIC-access address that is backed by a page of L1 physical memory. Next, set the APIC-access address to a (valid) L1 physical address that is not backed by memory. KVM can't handle this situation, so resuming L2 should result in a KVM exit for internal error (emulation).
