[PATCH] bpf: Deprecate "data" member of bpf_lpm_trie_key

by Kees Cook

The kernel is globally removing the ambiguous 0-length and 1-element arrays in favor of flexible arrays, so that we can gain both compile-time and run-time array bounds checking[1]. Most cases of these changes are trivial, but this case in BPF is not. It faces some difficulties: 1) struct bpf_lpm_trie_key is part of UAPI so changes can be fragile in the sense that projects external to Linux may be impacted. 2) The struct is intended to be used as a header, which means it may be within another structure, resulting in the "data" array member overlapping with the surrounding structure's following members. When converting from [0]-style to []-style, this overlap elicits warnings under Clang, and GCC considers it a deprecated extension (and similarly warns under -pedantic): https://godbolt.org/z/vWzqs41h6 3) Both the kernel and userspace access the existing "data" member for more than just static initializers and offsetof() calculations. For example: cilium: struct egress_gw_policy_key in_key = { .lpm_key = { 32 + 24, {} }, .saddr = CLIENT_IP, .daddr = EXTERNAL_SVC_IP & 0Xffffff, }; systemd: ipv6_map_fd = bpf_map_new( BPF_MAP_TYPE_LPM_TRIE, offsetof(struct bpf_lpm_trie_key, data) + sizeof(uint32_t)*4, sizeof(uint64_t), ...); ... struct bpf_lpm_trie_key *key_ipv4, *key_ipv6; ... memcpy(key_ipv4->data, &a->address, sizeof(uint32_t)); Searching for other uses in Debian Code Search seem to be just copies of UAPI headers: https://codesearch.debian.net/search?q=struct+bpf_lpm_trie_key&literal=1&pe… Introduce struct bpf_lpm_trie_key_u8 for the kernel (and future userspace) to use for walking the individual bytes following the header, and leave the "data" member of struct bpf_lpm_trie_key as-is (i.e. a [0]-style array). This will allow existing userspace code to continue to use "data" as a fake flexible array. The kernel (and future userspace code) building with -fstrict-flex-arrays=3 will see struct bpf_lpm_trie_key::data has having 0 bytes so there will be no overlap warnings, and can instead use struct bpf_lpm_trie_key_u8::data for accessing the actual byte array contents. The definition of struct bpf_lpm_trie_key_u8 uses a union with struct bpf_lpm_trie_key so that things like container_of() can be used instead of doing explicit casting, all while leaving the member names un-namespaced (i.e. key->prefixlen == key_u8->prefixlen, key->data == key_u8->data), allowing for trivial drop-in replacement without collateral member renaming. This will avoid structure overlap warnings and array bounds warnings while enabling run-time array bounds checking under CONFIG_UBSAN_BOUNDS=y and -fstrict-flex-arrays=3. For reference, the current warning under GCC 13 with -fstrict-flex-arrays=3 and -Warray-bounds is: ../kernel/bpf/lpm_trie.c:207:51: warning: array subscript i is outside array bounds of 'const __u8[0]' {aka 'const unsigned char[]'} [-Warray-bounds=] 207 | *(__be16 *)&key->data[i]); | ^~~~~~~~~~~~~ ../include/uapi/linux/swab.h:102:54: note: in definition of macro '__swab16' 102 | #define __swab16(x) (__u16)__builtin_bswap16((__u16)(x)) | ^ ../include/linux/byteorder/generic.h:97:21: note: in expansion of macro '__be16_to_cpu' 97 | #define be16_to_cpu __be16_to_cpu | ^~~~~~~~~~~~~ ../kernel/bpf/lpm_trie.c:206:28: note: in expansion of macro 'be16_to_cpu' 206 | u16 diff = be16_to_cpu(*(__be16 *)&node->data[i] ^ | ^~~~~~~~~~~ In file included from ../include/linux/bpf.h:7: ../include/uapi/linux/bpf.h:82:17: note: while referencing 'data' 82 | __u8 data[0]; /* Arbitrary size */ | ^~~~ Additionally update the samples and selftests to use the new structure, for demonstrating best practices.

[PATCH v1 0/3] kunit: fix bugs in debugfs logs

by Rae Moar

Currently, the KUnit debugfs logs have a few issues: 1. The results of parameterized tests don’t show up 2. The order of the lines in the logs is sometimes incorrect 3. There are extra new lines in the logs This patch series aims to fix these issues. This is an example of a debugfs log prior to these fixes: KTAP version 1 # Subtest: kunit_status 1..2 # kunit_status: pass:2 fail:0 skip:0 total:2 # Totals: pass:2 fail:0 skip:0 total:2 ok 1 kunit_status_set_failure_test ok 2 kunit_status_mark_skipped_test ok 1 kunit_status Note there is an extra line and a few of the lines are out of order. This is the same debugfs log after the fixes: KTAP version 1 # Subtest: kunit_status 1..2 ok 1 kunit_status_set_failure_test ok 2 kunit_status_mark_skipped_test # kunit_status: pass:2 fail:0 skip:0 total:2 # Totals: pass:2 fail:0 skip:0 total:2 ok 4 kunit_status This is now equivalent to the regular KTAP output for the kunit_status test.

[PATCH v3] selftests: use printf instead of echo -ne

by Guillaume Tucker

Rather than trying to guess which implementation of "echo" to run with support for "-ne" options, use "printf" instead of "echo -ne". It handles escape characters as a standard feature and it is widespread among modern shells. Reported-by: "kernelci.org bot" <bot(a)kernelci.org> Suggested-by: David Laight <David.Laight(a)ACULAB.COM> Fixes: 3297a4df805d ("kselftests: Enable the echo command to print newlines in Makefile") Fixes: 79c16b1120fe ("selftests: find echo binary to use -ne options") Signed-off-by: Guillaume Tucker <guillaume.tucker(a)collabora.com> --- Notes: v2: use printf insead of $(which echo) v3: rebase on top of fix with $(which echo) tools/testing/selftests/Makefile | 5 ++--- 1 file changed, 2 insertions(+), 3 deletions(-) diff --git a/tools/testing/selftests/Makefile b/tools/testing/selftests/Makefile index 9619d0f3b2ff..06578963f4f1 100644 --- a/tools/testing/selftests/Makefile +++ b/tools/testing/selftests/Makefile @@ -234,11 +234,10 @@ ifdef INSTALL_PATH @# While building kselftest-list.text skip also non-existent TARGET dirs: @# they could be the result of a build failure and should NOT be @# included in the generated runlist. - ECHO=`which echo`; \ for TARGET in $(TARGETS); do \ BUILD_TARGET=$$BUILD/$$TARGET; \ - [ ! -d $(INSTALL_PATH)/$$TARGET ] && $$ECHO "Skipping non-existent dir: $$TARGET" && continue; \ - $$ECHO -ne "Emit Tests for $$TARGET\n"; \ + [ ! -d $(INSTALL_PATH)/$$TARGET ] && printf "Skipping non-existent dir: $$TARGET\n" && continue; \ + printf "Emit Tests for $$TARGET\n"; \ $(MAKE) -s --no-print-directory OUTPUT=$$BUILD_TARGET COLLECTION=$$TARGET \ -C $$TARGET emit_tests >> $(TEST_LIST); \ done; -- 2.30.2
