2019-11-06mm/gup_benchmark: fix MAP_HUGETLB caseJohn Hubbard1-1/+1
The MAP_HUGETLB ("-H" option) of gup_benchmark fails: $ sudo ./gup_benchmark -H mmap: Invalid argument This is because gup_benchmark.c is passing in a file descriptor to mmap(), but the fd came from opening up the /dev/zero file. This confuses the mmap syscall implementation, which thinks that, if the caller did not specify MAP_ANONYMOUS, then the file must be a huge page file. So it attempts to verify that the file really is a huge page file, as you can see here: ksys_mmap_pgoff() { if (!(flags & MAP_ANONYMOUS)) { retval = -EINVAL; if (unlikely(flags & MAP_HUGETLB && !is_file_hugepages(file))) goto out_fput; /* THIS IS WHERE WE END UP */ else if (flags & MAP_HUGETLB) { ...proceed normally, /dev/zero is ok here... ...and of course is_file_hugepages() returns "false" for the /dev/zero file. The problem is that the user space program, gup_benchmark.c, really just wants anonymous memory here. The simplest way to get that is to pass MAP_ANONYMOUS whenever MAP_HUGETLB is specified, so that's what this patch does.

2019-10-30bpf: Allow narrow loads of bpf_sysctl fields with offset > 0Ilya Leoshkevich1-1/+7
"ctx:file_pos sysctl:read read ok narrow" works on s390 by accident: it reads the wrong byte, which happens to have the expected value of 0. Improve the test by seeking to the 4th byte and expecting 4 instead of 0. This makes the latent problem apparent: the test attempts to read the first byte of bpf_sysctl.file_pos, assuming this is the least-significant byte, which is not the case on big-endian machines: a non-zero offset is needed. The point of the test is to verify narrow loads, so we cannot cheat our way out by simply using BPF_W. The existence of the test means that such loads have to be supported, most likely because llvm can generate them. Fix the test by adding a big-endian variant, which uses an offset to access the least-significant byte of bpf_sysctl.file_pos. This reveals the final problem: verifier rejects accesses to bpf_sysctl fields with offset > 0. Such accesses are already allowed for a wide range of structs: __sk_buff, bpf_sock_addr and sk_msg_md to name a few. Extend this support to bpf_sysctl by using bpf_ctx_range instead of offsetof when matching field offsets.

2019-10-03udp: only do GSO if # of segs > 1Josh Hunt1-12/+4
Prior to this change an application sending <= 1MSS worth of data and enabling UDP GSO would fail if the system had SW GSO enabled, but the same send would succeed if HW GSO offload is enabled. In addition to this inconsistency the error in the SW GSO case does not get back to the application if sending out of a real device so the user is unaware of this failure. With this change we only perform GSO if the # of segments is > 1 even if the application has enabled segmentation. I've also updated the relevant udpgso selftests.

2019-10-01selftests/kselftest/runner.sh: Add 45 second timeout per testKees Cook2-3/+34
Commit a745f7af3cbd ("selftests/harness: Add 30 second timeout per test") solves the problem of kselftest_harness.h-using binary tests possibly hanging forever. However, scripts and other binaries can still hang forever. This adds a global timeout to each test script run. To make this configurable (e.g. as needed in the "rtc" test case), include a new per-test-directory "settings" file (similar to "config") that can contain kselftest-specific settings. The first recognized field is "timeout". Additionally, this splits the reporting for timeouts into a specific "TIMEOUT" not-ok (and adds exit code reporting in the remaining case).

Similarly, the initramfs may contain an appended signature. This contained a lot of refactoring of the existing appended signature verification code, so that IMA could retain the existing framework of calculating the file hash once, storing it in the IMA measurement list and extending the TPM, verifying the file's integrity based on a file hash or signature (eg. xattrs), and adding an audit record containing the file hash, all based on policy. (The IMA support for appended signatures patch set was posted and reviewed 11 times.)

2019-09-27mlxsw: spectrum: Clear VLAN filters during port initializationIdo Schimmel1-7/+0
When a port is created, its VLAN filters are not cleared by the firmware. This causes tagged packets to be later dropped by the ingress STP filters, which default to DISCARD state. The above did not matter much until commit b5ce611fd96e ("mlxsw: spectrum: Add devlink-trap support") where we exposed the drop reason to users. Without this patch, the drop reason users will see is not consistent. If a port is enslaved to a VLAN-aware bridge and a packet with an invalid VLAN tries to ingress the bridge, it will be dropped due to ingress STP filter. If the VLAN is later enabled and then disabled, the packet will be dropped by the ingress VLAN filter despite the above being a seemingly NOP operation. Fix this by clearing all the VLAN filters during port initialization. Adjust the test accordingly.
