* save-cwd: reduce default dependencyEric Blake2011-04-271-1/+2
| | | | | | | | | | | | | | | | | | | | | save-cwd generally needs only a working fchdir or a working getcwd(NULL,0). If you are not worried about directories whose absolute name is longer than PATH_MAX, then reducing the default dependencies reduces the bulk for this module. However, there are cases where neither function works on Linux (an unreadable but searchable directory can be opened by O_SEARCH, except that Linux doesn't implement that yet; and Linux getcwd() has issues with long absolute names which glibc does not work around but which the full-blown getcwd module does). So someone desiring a truly robust solution needs to import the 'getcwd' module at the same time as 'save-cwd'. * modules/save-cwd (Depends-on): Use getcwd-lgpl. * lib/save-cwd.c: Update comments. * NEWS: Document the semantic change. Signed-off-by: Eric Blake <eblake@redhat.com>
* save-cwd: no longer include "xgetcwd.h"Rob Vermaas2011-01-121-1/+0
| | | | | | * lib/save-cwd.c: Don't include "xgetcwd.h"; it's no longer used. This avoids a compilation failure in projects that use save-cwd without also using the xgetcwd module.
* save-cwd: remove #if-!HAVE_FCHDIR'd code; use the fchdir moduleJim Meyering2011-01-111-12/+0
| | | | | | | There is no need to work around the lack of the fchdir function, since gnulib can now provide a replacement when required. * lib/save-cwd.c: Remove #if !HAVE_FCHDIR...#endif code. * modules/save-cwd (Depends-on): Add fchdir.
* openat, save-cwd: avoid xmallocPaul Eggert2011-01-111-2/+2
| | | | | | | | | | | | | | | This removes a direct (but undocumented) dependency of openat on xalloc, along with an indirect dependency via save-cwd. It also removes a dependency of save-cwd on xgetcwd, and thereby indirectly on xalloc. This change causes the openat substitute to fall back on save_cwd when memory is tight, and for save_cwd to fail instead of dying when memory is tight, but that's good enough. * lib/openat-proc.c: Include stdlib.h (for malloc), not xalloc.h (for xmalloc). (openat_proc_name): Use malloc, not xmalloc. * lib/save-cwd.c (save_cwd): Use getcwd, not xgetcwd. * modules/save-cwd (Files): Depend on getcwd, not xgetcwd.
* maint: update almost all copyright ranges to include 2011Jim Meyering2011-01-011-1/+1

* fcntl-h, etc.: prefer O_SEARCH to O_RDONLY when applicablePaul Eggert2010-09-011-1/+1
| | | | | | | | | | | | | | | | | | | | POSIX 2008 specifies a new 'open' flag O_SEARCH, which can be used when one needs search access to a directory but not read access. On systems where it is available, it works in some cases where O_RDONLY does not, namely on directories that are searchable but not readable, and which need only to be searchable. If O_SEARCH is not available, fall back to the traditional method of using O_RDONLY. * lib/fcntl.in.h (O_SEARCH): #define to O_RDONLY if not defined. * lib/chdir-long.c (cdb_advance_fd): Use O_SEARCH, not O_RDONLY, when opening a directory that needs only to be searchable. * lib/chdir-safer.c (chdir_no_follow): Likewise. * lib/fts.c (diropen, fts_open, fd_ring_check): Likewise. * lib/openat-proc.c (openat_proc_name): Likewise. * lib/openat.c (openat_needs_fchdir): Likewise. * lib/save-cwd.c (save_cwd): Likewise. * lib/savewd.c (savewd_save, savewd_chdir): Likewise.
* save-cwd: don't leak a file descriptor when the caller execsJames Youngman2010-03-291-0/+2
| | | | | | * lib/save-cwd.c (save_cwd): set the close-on-exec flag for the saved file descriptor. * modules/save-cwd (Depends-on): Depend on cloexec.

(openat_permissive): Avoid writing to just-opened fd 2 if restoring the current directory fails. * lib/openat-die.c (openat_restore_fail): Add comment. * lib/save-cwd.c (includes): Make "fcntl--.h" conditional.

MOUNTED_GETMNTENT2 is new here; the code didn't used to look for dev= in that case. * lib/posixtm.h (PDS_PRE_2000): New macro. * lib/posixtm.c (year): Arg is now syntax_bits rather than allow_century. All usages changed. Reject dates outside the range 1969-1999 if PDS_PRE_2000 is used. * modules/mkdir-p (Files): Add chdir-safer.c, chdir-safer.h, lchmod.h, chdir-safer.m4, lchmod.m4. * modules/openat: Add mkdirat.c, openat-priv.h. * modules/lib-ignore: New file. * lib/version-etc.c (COPYRIGHT_YEAR): Update to 2006. Rewrite fts.c not to change the current working directory, by using openat, fstatat, fdopendir, etc.. * lib/fts.c [! _LIBC]: Include "openat.h", "unistd--.h", and "fcntl--.h". [_LIBC] (fchdir): Don't undef or define; no longer used. (FCHDIR): Define in terms of cwd_advance_fd rather than fchdir. Now, this `function' always succeeds, and consumes its file descriptor parameter -- so callers must not close such FDs. Update callers. (diropen_fd, opendirat, cwd_advance_fd): New functions. (diropen): Add parameter, SP. Adjust all callers. Implement using diropen_fd, rather than open. (fts_open): Initialize new member, fts_cwd_fd. Remove fts_rft-setting code. (fts_close): Close fts_cwd_fd, if necessary. (__opendir2): Define in terms of opendir or opendirat, depending on whether the FST_NOCHDIR flag is set. (fts_build): Since fts_safe_changedir consumes its FD, and since this code must do `closedir(dirp)', dup the dirfd(dirp) argument, and close the dup'd file descriptor upon failure. (fts_stat): Use fstatat(...AT_SYMLINK_NOFOLLOW) in place of lstat. (fts_safe_changedir): Tweak semantics to reflect that this function now calls cwd_advance_fd and hence consumes its FD argument. * lib/fts_.h [struct FTS] (fts_cwd_fd): New member. (fts_rft): Remove now-unused member. * lib/openat.c (fchownat): New function. * lib/openat.h (fchmodat, fchownat): Declare. (chmodat, lchmodat): Define convenience functions. (chownat, lchownat): Likewise. * lib/chdir-safer.h, chdir-safer.c: New files. * lib/modechange.c (mode_compile): Reject an invalid mode string that starts with an octal digit. From Andreas Gruenbacher. * lib/openat.c: Include "fcntl--.h" and "unistd--.h", to map open and dup to open_safer and dup_safer, respectively. (openat_permissive): Fix typo in comment. * lib/openat.c: Don't include <stdlib.h>, <unistd.h>, <fcntl.h>, "gettext.h"; either no longer needed or are guaranteed by openat.h. (_): Remove; no longer needed. (openat): Renamed from rpl_openat; no need for rpl_openat since openat.h renames openat for us. Replace most of the body with a call to openat_permissive, to avoid duplicate code. Port to (probably hypothetical) environments were mode_t is wider than int. (openat_permissive): Require mode arg, so that we can check types better. Put it just after flags. Change cwd failure indicator from pointer-to-bool to pointer-to-errno-value. All callers changed. Invoke openat_save_fail and/or openat_restore_fail if cwd_errno is null, so that openat can call us. (openat_permissive, fdopendir, fstatat, unlinkat): Simplify errno handling to avoid some duplicate code, as it's OK to set errno on success. * lib/openat.h: Revamp code so that function macros depend on __OPENAT_PREFIX only, not also on AT_FDCWD. (openat_ro): Remove. Caller changed to use openat_permissive. (openat_permissive): Now a macro, if not a function. (openat_restore_fail, openat_save_fail): Now always functions, since mkdirat needs them even if __OPENAT_PREFIX is defined. * lib/openat-priv.h: New file, defining macros used by mkdirat.c and openat.c. * lib/mkdirat.c: Include openat-priv.h. Remove definitions of macros defined therein. * lib/openat.c: Likewise. * lib/mkdirat.c (mkdirat): New file and function. * lib/openat.h (mkdirat): Declare. * lib/openat.c (fdopendir): Don't change errno when returning non-NULL. * lib/openat.h (openat_permissive): Declare. (openat_ro): Define. * lib/openat.c (EXPECTED_ERRNO): New macro. (openat_permissive): New function -- used in remove.c rewrite. (all functions): Set errno just before returning, only if there was an actual failure. Use EXPECTED_ERRNO rather than comparing against only ENOTDIR. Emulate openat-family functions using Linux's procfs, if possible. Idea and some code based on Ulrich Drepper's glibc changes. * lib/openat.c: (BUILD_PROC_NAME): New macro. Include <stdio.h>, <string.h>, "alloca.h" and "intprops.h". (rpl_openat): Emulate by trying to open /proc/self/fd/%d/%s, before falling back on save_cwd and restore_cwd. (fdopendir, fstatat, unlinkat): Likewise. * lib/openat.c (fstatat, unlinkat): Perform the syscall directly, skipping the save_cwd...restore_cwd overhead, if FILE is absolute. * lib/openat.c (rpl_openat): Use the promoted type (int), not mode_t, as second argument to va_arg. Otherwise, some versions of gcc warn that `if this code is reached, the program will abort'. Add POSIX ACL support * lib/acl.h (copy_acl, set_acl): Add declarations. * lib/acl.c (acl_entries): Add fallback implementation for POSIX ACL systems other than Linux. (chmod_or_fchmod): New function: use fchmod when possible, and chmod otherwise. (file_has_acl): Add a POSIX ACL implementation, with a Linux-specific subcase. (copy_acl): Add: copy an acl and S_ISUID, S_ISGID, and S_ISVTX from one file to another. Fall back to fchmod/chmod when acls are unsupported. (set_acl): Add: set a file's acl and S_ISUID, S_ISGID, and S_ISVTX to a defined value. Fall back to fchmod/chmod when acls are unsupported. * m4/lib-ignore.m4: New file. * m4/lchmod.m4: New file. * m4/chdir-safer.m4: New file. * m4/openat.m4 (gl_FUNC_OPENAT): Require and compile mkdirat.c. Require openat-priv.h. * m4/acl.m4 (AC_FUNC_ACL): Add POSIX ACL and Linux-specific acl tests.
