Eric Blake 9cd8acba 2009-11-12T21:45:20 chown: detect Solaris and FreeBSD bug Solaris 9 and FreeBSD 7.2 chown("link-to-file/",uid,gid) mistakenly changes ownership of "file". * lib/chown.c (rpl_chown): Work around bug. * m4/chown.m4 (gl_FUNC_CHOWN): Check for trailing slash bugs. (gl_PREREQ_CHOWN): Delete. * m4/unistd_h.m4 (gl_UNISTD_H_DEFAULTS): Add witness. * modules/unistd (Makefile.am): Populate it. * lib/unistd.in.h (chown): Update declaration. * lib/lchown.c (chown): Update client. * modules/lchown (Depends-on): Add lstat. * doc/posix-functions/chown.texi (chown): Document the bug. * doc/posix-functions/getgroups.texi (getgroups): Document getgroups pitfall. * modules/chown-tests: New file. * tests/test-chown.h (test_chown): Likewise. * tests/test-chown.c (main): Likewise.

Eric Blake 1e642be9 2009-11-13T12:53:17 getgroups: work around FreeBSD bug FreeBSD 7.2 mistakenly succeeds on getgroups(-1,ptr) (POSIX requires EINVAL failure since -1 is less than the proper result). * lib/getgroups.c (rpl_getgroups): Work around the bug. * m4/getgroups.m4 (gl_FUNC_GETGROUPS): Detect the bug. * doc/posix-functions/getgroups.texi (getgroups): Document it. * tests/test-getgroups.c (main): Fix buffer overrun.

Eric Blake 6e4b15b5 2009-11-12T10:19:39 getgroups: don't expose GETGROUPS_T to user These days, most systems already declare getgroups with gid_t*. But in the rare case that GETGROUPS_T is still int but gid_t is short, the user should not have to uglify their code; let the replacement hide all the magic. Tested by configuring with ac_cv_type_getgroups=uint64_t on a platform with 32-bit gid_t, and ignoring compiler warnings. However, since we don't replace setgroups, the GETGROUPS_T workaround is still needed there for now. * lib/getgroups.c (rpl_getgroups): Change signature. Copy array an element at a time if GETGROUPS_T is wrong size. * lib/getugroups.h (getugroups): Change signature. * lib/unistd.in.h (getgroups): Likewise. * m4/getgroups.m4 (gl_FUNC_GETGROUPS): Use replacement if signature needs fixing. * m4/getugroups.m4 (gl_GETUGROUPS): No longer need AC_TYPE_GETGROUPS. * modules/group-member (Depends-on): Add getgroups. * lib/group-member.c (group_info, get_group_info): Use gid_t. (group_member): Rely on getgroups replacement. * lib/getugroups.c (getugroups): Use gid_t. * tests/test-getgroups.c (main): Likewise. * NEWS: Mention the signature change. * doc/posix-functions/getgroups.texi (getgroups): Mention the problem with signature. * doc/glibc-functions/setgroups.texi (setgroups): Mention that GETGROUPS_T is still useful for setgroups.
