https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D211873 Bug ID: 211873 Summary: lib/libc/gen/basedirname_test:dirname_posix fails: "Input buffer was modified." Product: Base System Version: CURRENT Hardware: Any OS: Any Status: New Severity: Affects Only Me Priority: --- Component: tests Assignee: freebsd-testing@freebsd.org Reporter: ngie@FreeBSD.org Looks like the behavior for dirname(3) on FreeBSD deviates from NetBSD. Bringing this up because we may or may not want to follow suit. Assigning to ed@ because he's been heading up the recent basename(3)/dirnam= e(3) POSIXification. $ svn info /usr/src/svn/ Path: /usr/src/svn Working Copy Root Path: /usr/src/svn URL: svn+ssh://ngie@repo.freebsd.org/base/projects/netbsd-tests-update-12 Relative URL: ^/projects/netbsd-tests-update-12 Repository Root: svn+ssh://ngie@repo.freebsd.org/base Repository UUID: ccf9f872-aa2e-dd11-9fc8-001c23d0bc1f Revision: 304099 Node Kind: directory Schedule: normal Last Changed Author: ngie Last Changed Rev: 304099 Last Changed Date: 2016-08-14 12:54:40 -0700 (Sun, 14 Aug 2016) $ kyua debug -k lib/libc/gen/Kyuafile basedirname_test:dirname_posix Input buffer for "/usr/lib" was modified basedirname_test:dirname_posix -> failed: Input buffer was modified. 165 /* 166 * dirname(3) is allowed to modify the input buffer. 167 * However, that is considered hostile by some programs, 168 * and so we elect to consider this an error. 169 * 170 * This is not a problem, as dirname(3) is also allowed 171 * to return a pointer to a statically-allocated buffer 172 * (it is explicitly not required to be reentrant). 173 */ 174 if (test_dirname_table[i].input !=3D NULL && 175 strcmp(test_dirname_table[i].input, testbuf) !=3D 0= ) { 176 fprintf(stderr, 177 "Input buffer for \"%s\" was modified\n", 178 test_dirname_table[i].input); 179 atf_tc_fail("Input buffer was modified."); 180 } --=20 You are receiving this mail because: You are the assignee for the bug.=
