2022-03-23	libctf, ld: diagnose corrupted CTF header cth_strlen	Nick Alcock	1	-1/+1
	The last section in a CTF dict is the string table, at an offset represented by the cth_stroff header field. Its length is recorded in the next field, cth_strlen, and the two added together are taken as the size of the CTF dict. Upon opening a dict, we check that none of the header offsets exceed this size, and we check when uncompressing a compressed dict that the result of the uncompression is the same length: but CTF dicts need not be compressed, and short ones are not. Uncompressed dicts just use the ctf_size without checking it. This field is thankfully almost unused: it is mostly used when reserializing a dict, which can't be done to dicts read off disk since they're read-only. However, when opening an uncompressed foreign-endian dict we have to copy it out of the mmaped region it is stored in so we can endian- swap it, and we use ctf_size when doing that. When the cth_strlen is corrupt, this can overrun. Fix this by checking the ctf_size in all uncompressed cases, just as we already do in the compressed case. Add a new test. This came to light because various corrupted-CTF raw-asm tests had an incorrect cth_strlen: fix all of them so they produce the expected error again. libctf/ PR libctf/28933 * ctf-open.c (ctf_bufopen_internal): Always check uncompressed CTF dict sizes against the section size in case the cth_strlen is corrupt. ld/ PR libctf/28933 * testsuite/ld-ctf/diag-strlen-invalid.: New test, derived from diag-cttname-invalid.s. testsuite/ld-ctf/diag-cttname-invalid.s: Fix incorrect cth_strlen. * testsuite/ld-ctf/diag-cttname-null.s: Likewise. * testsuite/ld-ctf/diag-cuname.s: Likewise. * testsuite/ld-ctf/diag-parlabel.s: Likewise. * testsuite/ld-ctf/diag-parname.s: Likewise.
2020-07-22	ld: new CTF testsuite	Egeyar Bagcioglu	1	-0/+44
	Uses the new cc option to run_dump_test to compile most tests from C code, ensuring that the types in the C code accurately describe what the .d file is testing. (Some tests, mostly those testing malformed CTF, run directly from .s, or include both .s and .c.) ld/ * testsuite/ld-ctf/ctf.exp: New file. * testsuite/ld-ctf/A-2.c: New file. * testsuite/ld-ctf/A.c: New file. * testsuite/ld-ctf/B-2.c: New file. * testsuite/ld-ctf/B.c: New file. * testsuite/ld-ctf/C-2.c: New file. * testsuite/ld-ctf/C.c: New file. * testsuite/ld-ctf/array-char.c: New file. * testsuite/ld-ctf/array-int.c: New file. * testsuite/ld-ctf/array.d: New file. * testsuite/ld-ctf/child-float.c: New file. * testsuite/ld-ctf/child-int.c: New file. * testsuite/ld-ctf/conflicting-cycle-1.B-1.d: New file. * testsuite/ld-ctf/conflicting-cycle-1.B-2.d: New file. * testsuite/ld-ctf/conflicting-cycle-1.parent.d: New file. * testsuite/ld-ctf/conflicting-cycle-2.A-1.d: New file. * testsuite/ld-ctf/conflicting-cycle-2.A-2.d: New file. * testsuite/ld-ctf/conflicting-cycle-2.parent.d: New file. * testsuite/ld-ctf/conflicting-cycle-3.C-1.d: New file. * testsuite/ld-ctf/conflicting-cycle-3.C-2.d: New file. * testsuite/ld-ctf/conflicting-cycle-3.parent.d: New file. * testsuite/ld-ctf/conflicting-enums.d: New file. * testsuite/ld-ctf/conflicting-typedefs.d: New file. * testsuite/ld-ctf/cross-tu-1.c: New file. * testsuite/ld-ctf/cross-tu-2.c: New file. * testsuite/ld-ctf/cross-tu-conflicting-2.c: New file. * testsuite/ld-ctf/cross-tu-cyclic-1.c: New file. * testsuite/ld-ctf/cross-tu-cyclic-2.c: New file. * testsuite/ld-ctf/cross-tu-cyclic-3.c: New file. * testsuite/ld-ctf/cross-tu-cyclic-4.c: New file. * testsuite/ld-ctf/cross-tu-cyclic-conflicting.d: New file. * testsuite/ld-ctf/cross-tu-cyclic-nonconflicting.d: New file. * testsuite/ld-ctf/cross-tu-into-cycle.d: New file. * testsuite/ld-ctf/cross-tu-noncyclic.d: New file. * testsuite/ld-ctf/cycle-1.c: New file. * testsuite/ld-ctf/cycle-1.d: New file. * testsuite/ld-ctf/cycle-2.A.d: New file. * testsuite/ld-ctf/cycle-2.B.d: New file. * testsuite/ld-ctf/cycle-2.C.d: New file. * testsuite/ld-ctf/diag-ctf-version-0.d: New file. * testsuite/ld-ctf/diag-ctf-version-0.s: New file. * testsuite/ld-ctf/diag-ctf-version-2-unsupported-feature.d: New file. * testsuite/ld-ctf/diag-ctf-version-2-unsupported-feature.s: New file. * testsuite/ld-ctf/diag-ctf-version-f.d: New file. * testsuite/ld-ctf/diag-ctf-version-f.s: New file. * testsuite/ld-ctf/diag-cttname-invalid.d: New file. * testsuite/ld-ctf/diag-cttname-invalid.s: New file. * testsuite/ld-ctf/diag-cttname-null.d: New file. * testsuite/ld-ctf/diag-cttname-null.s: New file. * testsuite/ld-ctf/diag-cuname.d: New file. * testsuite/ld-ctf/diag-cuname.s: New file. * testsuite/ld-ctf/diag-decompression-failure.d: New file. * testsuite/ld-ctf/diag-decompression-failure.s: New file. * testsuite/ld-ctf/diag-parlabel.d: New file. * testsuite/ld-ctf/diag-parlabel.s: New file. * testsuite/ld-ctf/diag-parname.d: New file. * testsuite/ld-ctf/diag-parname.s: New file. * testsuite/ld-ctf/diag-unsupported-flag.d: New file. * testsuite/ld-ctf/diag-unsupported-flag.s: New file. * testsuite/ld-ctf/diag-wrong-magic-number-mixed.d: New file. * testsuite/ld-ctf/diag-wrong-magic-number.d: New file. * testsuite/ld-ctf/diag-wrong-magic-number.s: New file. * testsuite/ld-ctf/enum-2.c: New file. * testsuite/ld-ctf/enum.c: New file. * testsuite/ld-ctf/function.c: New file. * testsuite/ld-ctf/function.d: New file. * testsuite/ld-ctf/slice.c: New file. * testsuite/ld-ctf/slice.d: New file. * testsuite/ld-ctf/super-sub-cycles.c: New file. * testsuite/ld-ctf/super-sub-cycles.d: New file. * testsuite/ld-ctf/typedef-int.c: New file. * testsuite/ld-ctf/typedef-long.c: New file. * testsuite/ld-ctf/union-1.c: New file.
