2021-09-10riscv: defconfig: enable NLS_CODEPAGE_437, NLS_ISO8859_1Heinrich Schuchardt
The EFI system partition uses the FAT file system. Many distributions add an entry in /etc/fstab for the ESP. We must ensure that mounting does not fail. The default code page for FAT is 437 (cf. CONFIG_FAT_DEFAULT_CODEPAGE). The default IO character set is "iso8859-1" (cf. CONFIG_NLS_ISO8859_1). So let's enable NLS_CODEPAGE_437 and NLS_ISO8859_1 in defconfig.

2021-09-10riscv: defconfig: enable BLK_DEV_NVMEHeinrich Schuchardt
NVMe is a non-volatile storage media attached via PCIe. As NVMe has much higher throughput than other block devices like SATA it is a must have for RISC-V. Enable CONFIG_BLK_DEV_NVME. The HiFive Unmatched is a board providing M.2 slots for NVMe drives. Enable CONFIG_PCIE_FU740.

2021-09-11thermal: Replace deprecated CPU-hotplug functions.Sebastian Andrzej Siewior
The functions get_online_cpus() and put_online_cpus() have been deprecated during the CPU hotplug rework. They map directly to cpus_read_lock() and cpus_read_unlock(). Replace deprecated CPU-hotplug functions with the official version. The behavior remains unchanged.

Ensure that all usage sites of get/put_online_cpus() except for the struggler in drivers/thermal are gone. So the last user and the deprecated inlines can be removed.

The btf__get_from_id() function was deprecated in favour of btf__load_from_kernel_by_id(), but it is still avaiable, so use it to provide a weak function btf__load_from_kernel_by_id() for older libbpf when building perf with LIBBPF_DYNAMIC=1, i.e. using the system's libbpf package.

BPF programs may want to know hardware timestamps if NIC supports such timestamping. Expose this data as hwtstamp field of __sk_buff the same way as gso_segs/gso_size. This field could be accessed from the same programs as tstamp field, but it's read-only field. Explicit test to deny access to padding data is added to bpf_skb_is_valid_access.

2021-09-10perf report: Add support to print a textual representation of IBS raw sample ↵Kim Phillips
data Perf records IBS (Instruction Based Sampling) extra sample data when 'perf record --raw-samples' is used with an IBS-compatible event, on a machine that supports IBS. IBS support is indicated in CPUID_Fn80000001_ECX bit #10. Up until now, users have been able to see the extra sample data solely in raw hex format using 'perf report --dump-raw-trace'. From there, users could decode the data either manually, or by using an external script. Enable the built-in 'perf report --dump-raw-trace' to do the decoding of the extra sample data bits, so manual or external script decoding isn't necessary. Example usage: $ sudo perf record -c 10000001 -a --raw-samples -e ibs_fetch/rand_en=1/,ibs_op/cnt_ctl=1/ -C 0,1 taskset -c 0,1 7za b -mmt2 | perf report --dump-raw-trace Stdout contains IBS Fetch samples, e.g.: ibs_fetch_ctl: 02170007ffffffff MaxCnt 1048560 Cnt 1048560 Lat 7 En 1 Val 1 Comp 1 IcMiss 0 PhyAddrValid 1 L1TlbPgSz 4KB L1TlbMiss 0 L2TlbMiss 0 RandEn 1 L2Miss 0 IbsFetchLinAd: 000056016b2ead40 IbsFetchPhysAd: 000000115cedfd40 c_ibs_ext_ctl: 0000000000000000 IbsItlbRefillLat 0 ..and IBS Op samples, e.g.: ibs_op_ctl: 0000009e009e8968 MaxCnt 10000000 En 1 Val 1 CntCtl 1=uOps CurCnt 158 IbsOpRip: 000056016b2ea73d ibs_op_data: 00000000000b0002 CompToRetCtr 2 TagToRetCtr 11 BrnRet 0 RipInvalid 0 BrnFuse 0 Microcode 0 ibs_op_data2: 0000000000000002 CacheHitSt 0=M-state RmtNode 0 DataSrc 2=Local node cache ibs_op_data3: 0000000000c60002 LdOp 0 StOp 1 DcL1TlbMiss 0 DcL2TlbMiss 0 DcL1TlbHit2M 0 DcL1TlbHit1G 0 DcL2TlbHit2M 0 DcMiss 0 DcMisAcc 0 DcWcMemAcc 0 DcUcMemAcc 0 DcLockedOp 0 DcMissNoMabAlloc 0 DcLinAddrValid 1 DcPhyAddrValid 1 DcL2TlbHit1G 0 L2Miss 0 SwPf 0 OpMemWidth 4 bytes OpDcMissOpenMemReqs 0 DcMissLat 0 TlbRefillLat 0 IbsDCLinAd: 00007f133c319ce0 IbsDCPhysAd: 0000000270485ce0 Committer notes: Fixed up this: util/amd-sample-raw.c: In function ‘evlist__amd_sample_raw’: util/amd-sample-raw.c:125:42: error: ‘ bytes’ directive output may be truncated writing 6 bytes into a region of size between 4 and 7 [-Werror=format-truncation=] 125 | " OpMemWidth %2d bytes", 1 << (reg.op_mem_width - 1)); | ^~~~~~ In file included from /usr/include/stdio.h:866, from util/amd-sample-raw.c:7: /usr/include/bits/stdio2.h:71:10: note: ‘__builtin___snprintf_chk’ output between 21 and 24 bytes into a destination of size 21 71 | return __builtin___snprintf_chk (__s, __n, __USE_FORTIFY_LEVEL - 1, | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 72 | __glibc_objsize (__s), __fmt, | ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 73 | __va_arg_pack ()); | ~~~~~~~~~~~~~~~~~ cc1: all warnings being treated as errors As that %2d won't limit the number of chars to 2, just state that 2 is the minimal width: $ cat printf.c #include <stdio.h> #include <stdlib.h> int main(int argc, char *argv[]) { char bf[64]; int len = snprintf(bf, sizeof(bf), "%2d", atoi(argv[1])); printf("strlen(%s): %u\n", bf, len); return 0; } $ ./printf 1 strlen( 1): 2 $ ./printf 12 strlen(12): 2 $ ./printf 123 strlen(123): 3 $ ./printf 1234 strlen(1234): 4 $ ./printf 12345 strlen(12345): 5 $ ./printf 123456 strlen(123456): 6 $ And since we probably don't want that output to be truncated, just assume the worst case, as the compiler did, and add a few more chars to that buffer. Also use sizeof(var) instead of sizeof(dup-of-wanted-format-string) to avoid bugs when changing one but not the other. I also had to change this: -#include <asm/amd-ibs.h> +#include "../../arch/x86/include/asm/amd-ibs.h" To make it build on other architectures, just like intel-pt does.

2021-09-10perf report: Add tools/arch/x86/include/asm/amd-ibs.hKim Phillips
This is a tools/-side patch for the patch that adds the original copy of the IBS header file, in arch/x86/include/asm/. We also add an entry to check-headers.sh, so future changes continue to be copied. Committer notes: Had to add this -#include <asm/msr-index.h> +#include "msr-index.h" And change the check-headers.sh entry to ignore this line when diffing with the original kernel header. This is needed so that we can use 'perf report' on a perf.data with IBS data on a !x86 system, i.e. building on ARM fails without this as there is no asm/msr-index.h there. This was done on the next patch in this series and is done for things like Intel PT and ARM CoreSight.

Since mm->mmap_lock is not held in bpf_get_stack[id]() use case, the above warning is emitted during test run. This patch fixed the issue by (1). using mmap_read_trylock() instead of mmap_read_trylock_non_owner() to satisfy lockdep checking in find_vma(), and (2). droping lockdep for mmap_lock right before the irq_work_queue(). The function mmap_read_trylock_non_owner() is also removed since after this patch nobody calls it any more.

2021-09-10Merge branch 'bpf-xsk-selftests'Daniel Borkmann
Magnus Karlsson says: ==================== This patch set facilitates adding new tests as well as describing existing ones in the xsk selftests suite and adds 3 new test suites at the end. The idea is to isolate the run-time that executes the test from the actual implementation of the test. Today, implementing a test amounts to adding test specific if-statements all around the run-time, which is not scalable or amenable for reuse. This patch set instead introduces a test specification that is the only thing that a test fills in. The run-time then gets this specification and acts upon it completely unaware of what test it is executing. This way, we can get rid of all test specific if-statements from the run-time and the implementation of the test can be contained in a single function. This hopefully makes it easier to add tests and for users to understand what the test accomplishes. As a recap of what the run-time does: each test is based on the run-time launching two threads and connecting a veth link between the two threads. Each thread opens an AF_XDP socket on that veth interface and one of them sends traffic that the other one receives and validates. Each thread has its own umem. Note that this behavior is not changed by this patch set. A test specification consists of several items. Most importantly: * Two packet streams. One for Tx thread that specifies what traffic to send and one for the Rx thread that specifies what that thread should receive. If it receives exactly what is specified, the test passes, otherwise it fails. A packet stream can also specify what buffers in the umem that should be used by the Rx and Tx threads. * What kind of AF_XDP sockets it should create and bind to what interfaces * How many times it should repeat the socket creation and destruction * The name of the test The interface for the test spec is the following: void test_spec_init(struct test_spec *test, struct ifobject *ifobj_tx, struct ifobject *ifobj_rx, enum test_mode mode); /* Reset everything but the interface specifications and the mode */ void test_spec_reset(struct test_spec *test); void test_spec_set_name(struct test_spec *test, const char *name); Packet streams have the following interfaces: struct pkt *pkt_stream_get_pkt(struct pkt_stream *pkt_stream, u32 pkt_nb) struct pkt *pkt_stream_get_next_rx_pkt(struct pkt_stream *pkt_stream) struct pkt_stream *pkt_stream_generate(struct xsk_umem_info *umem, u32 nb_pkts, u32 pkt_len); void pkt_stream_delete(struct pkt_stream *pkt_stream); struct pkt_stream *pkt_stream_clone(struct xsk_umem_info *umem, struct pkt_stream *pkt_stream); /* Replaces all packets in the stream*/ void pkt_stream_replace(struct test_spec *test, u32 nb_pkts, u32 pkt_len); /* Replaces every other packet in the stream */ void pkt_stream_replace_half(struct test_spec *test, u32 pkt_len, u32 offset); /* For creating custom made packet streams */ void pkt_stream_generate_custom(struct test_spec *test, struct pkt *pkts, u32 nb_pkts); /* Restores the default packet stream */ void pkt_stream_restore_default(struct test_spec *test); A test can then then in the most basic case described like this (provided the test specification has been created before calling the function): static bool testapp_aligned(struct test_spec *test) { test_spec_set_name(test, "RUN_TO_COMPLETION"); testapp_validate_traffic(test); } Running the same test in unaligned mode would then look like this: static bool testapp_unaligned(struct test_spec *test) { if (!hugepages_present(test->ifobj_tx)) { ksft_test_result_skip("No 2M huge pages present.\n"); return false; } test_spec_set_name(test, "UNALIGNED_MODE"); test->ifobj_tx->umem->unaligned_mode = true; test->ifobj_rx->umem->unaligned_mode = true; /* Let half of the packets straddle a buffer boundrary */ pkt_stream_replace_half(test, PKT_SIZE, XSK_UMEM__DEFAULT_FRAME_SIZE - 32); /* Populate fill ring with addresses in the packet stream */ test->ifobj_rx->pkt_stream->use_addr_for_fill = true; testapp_validate_traffic(test); pkt_stream_restore_default(test); return true; } 3 of the last 4 patches in the set add 3 new test suites, one for unaligned mode, one for testing the rejection of tricky invalid descriptors plus the acceptance of some valid ones in the Tx ring, and one for testing 2K frame sizes (the default is 4K). What is left to do for follow-up patches: * Convert the statistics tests to the new framework. * Implement a way of registering new tests without having the enum test_type. Once this has been done (together with the previous bullet), all the test types can be dropped from the header file. This means that we should be able to add tests by just writing a single function with a new test specification, which is one of the goals. * Introduce functions for manipulating parts of the test or interface spec instead of direct manipulations such as test->ifobj_rx->pkt_stream->use_addr_for_fill = true; which is kind of awkward. * Move the run-time and its interface to its own .c and .h files. Then we can have all the tests in a separate file. * Better error reporting if a test fails. Today it does not state what test fails and might not continue execute the rest of the tests due to this failure. Failures are not propagated upwards through the functions so a failed test will also be a passed test, which messes up the stats counting. This needs to be changed. * Add option to run specific test instead of all of them * Introduce pacing of sent packets so that they are never dropped by the receiver even if it is stalled for some reason. If you run the current tests on a heavily loaded system, they might fail in SKB mode due to packets being dropped by the driver on Tx. Though I have never seen it, it might happen. v1 -> v2: * Fixed a number of spelling errors [Maciej] * Fixed use after free bug in pkt_stream_replace() [Maciej] * pkt_stream_set -> pkt_stream_generate_custom [Maciej] * Fixed formatting problem in testapp_invalid_desc() [Maciej] ==================== Signed-off-by: Daniel Borkmann <daniel@iogearbox.net>

Add a test for unaligned mode in which packet buffers can be placed anywhere within the umem. Some packets are made to straddle page boundaries in order to check for correctness. On the Tx side, buffers are now allocated according to the addresses found in the packet stream. Thus, the placement of buffers can be controlled with the boolean use_addr_for_fill in the packet stream. One new pkt_stream interface is introduced: pkt_stream_replace_half() that replaces every other packet in the default packet stream with the specified new packet. The constant DEFAULT_OFFSET is also introduced. It specifies at what offset from the start of a chunk a Tx packet is placed by the sending thread. This is just to be able to test that it is possible to send packets at an offset not equal to zero.

2021-09-10selftests: xsk: Introduce test specificationsMagnus Karlsson
Introduce a test specification to be able to concisely describe a test. Currently, a test is implemented by sprinkling test specific if statements here and there, which is not scalable or easy to understand. The end goal with this patch set is to come to the point in which a test is completely specified by a test specification that can easily be constructed in a single function so that new tests can be added without too much trouble. This test specification will be run by a test runner that has no idea about tests. It just executes the what test specification states. This patch introduces the test specification and, as a start, puts the two interface objects in there, one containing the packet stream to be sent and the other one the packet stream that is supposed to be received for a test to pass. The global variables containing these can then be eliminated. The following patches will convert each existing test into a test specification and add the needed fields into it and the functionality in the test runner that act on the test specification. At the end, the test runner should contain no test specific code and each test should be described in a single simple function.
