Paul Eggert 73dcdb9f30 Use faccessat, not access, when checking file permissions.
This fixes a bug that has been present in Emacs since its creation.
It was reported by Chris Torek in 1983 even before GNU Emacs existed,
which must set some sort of record.  (Torek's bug report was against
a predecessor of GNU Emacs, but GNU Emacs happened to have the
same common flaw.)  See Torek's Usenet posting
"setuid/setgid programs & Emacs" Article-I.D.: sri-arpa.858
Posted: Fri Apr  8 14:18:56 1983.
* .bzrignore: Add lib/fcntl.h.
* configure.ac (euidaccess): Remove check; gnulib does this for us now.
(gl_FCNTL_O_FLAGS): Define a dummy version.
* lib/at-func.c, lib/euidaccess.c, lib/faccessat.c, lib/fcntl.in.h:
* lib/getgroups.c, lib/group-member.c, lib/root-uid.h:
* lib/xalloc-oversized.h, m4/euidaccess.m4, m4/faccessat.m4:
* m4/fcntl_h.m4, m4/getgroups.m4, m4/group-member.m4:
New files, from gnulib.
* lib/gnulib.mk, m4/gnulib-comp.m4: Regenerate.
* admin/merge-gnulib (GNULIB_MODULES): Add faccessat.
(GNULIB_TOOL_FLAGS): Avoid at-internal, fchdir, malloc-posix,
openat-die, openat-h, save-cwd.  Do not avoid fcntl-h.
Omit gnulib's m4/fcntl-o.m4.
* nt/inc/ms-w32.h (AT_FDCWD, AT_EACCESS): New symbols.
(access): Remove.
(faccessat): New macro.
* src/Makefile.in (LIB_EACCESS): New macro.
(LIBES): Use it.
* src/callproc.c (init_callproc):
* src/charset.c (init_charset):
* src/fileio.c (check_existing, check_executable, check_writable)
(Ffile_readable_p):
* src/lread.c (openp, load_path_check):
* src/process.c (allocate_pty):
* src/xrdb.c (file_p):
Use effective UID when checking permissions, not real UID.
* src/callproc.c (init_callproc):
* src/charset.c (init_charset):
* src/lread.c (load_path_check, init_lread):
Test whether directories are accessible, not merely whether they exist.
* src/conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): New macro.
* src/fileio.c (check_existing, check_executable, check_writable)
(Ffile_readable_p):
Use symbolic names instead of integers for the flags, as they're
portable now.
(check_writable): New arg AMODE.  All uses changed.
Set errno on failure.
(Ffile_readable_p): Use faccessat, not stat + open + close.
(Ffile_writable_p): No need to call check_existing + check_writable.
Just call check_writable and then look at errno.  This saves a syscall.
dir should never be nil; replace an unnecessary runtime check
with an eassert.  When checking the parent directory of a nonexistent
file, check that the directory is searchable as well as writable, as
we can't create files in unsearchable directories.
(file_directory_p): New function, which uses 'stat' on most platforms
but faccessat with D_OK (for efficiency) if WINDOWSNT.
(Ffile_directory_p, Fset_file_times): Use it.
(file_accessible_directory_p): New function, which uses a single
syscall for efficiency.
(Ffile_accessible_directory_p): Use it.
* src/xrdb.c (file_p): Use file_directory_p.
* src/lisp.h (file_directory_p, file_accessible_directory_p): New decls.
* src/lread.c (openp): When opening a file, use fstat rather than
stat, as that avoids a permissions race.  When not opening a file,
use file_directory_p rather than stat.
(dir_warning): First arg is now a usage string, not a format.
Use errno.  All uses changed.
* src/nsterm.m (ns_term_init): Remove unnecessary call to file-readable
that merely introduced a race.
* src/process.c, src/sysdep.c, src/term.c: All uses of '#ifdef O_NONBLOCK'
changed to '#if O_NONBLOCK', to accommodate gnulib O_* style,
and similarly for the other O_* flags.
* src/w32.c (sys_faccessat): Rename from sys_access and switch to
faccessat's API.  All uses changed.
* src/xrdb.c: Do not include <sys/stat.h>; no longer needed.
(magic_db): Rename from magic_file_p.
(magic_db, search_magic_path): Return an XrmDatabase rather than a
char *, so that we don't have to test for file existence
separately from opening the file for reading.  This removes a race
fixes a permission-checking problem, and simplifies the code.
All uses changed.
(file_p): Remove; no longer needed.

### Bootstrapping.
## Bootstrapping right is difficult because of the circular dependencies.
## Furthermore, we have to deal with the fact that many compilation targets
## such as loaddefs.el or *.elc can typically be produced by any old
## Emacs executable, so we would like to avoid rebuilding them whenever
## we build a new Emacs executable.
## To solve the circularity, we use 2 different Emacs executables,
## "emacs" is the main target and "bootstrap-emacs" is the one used
## to build the *.elc and loaddefs.el files.
## To solve the freshness issue, we used to use a third file "witness-emacs"
## which was used to witness the fact that there is a bootstrap-emacs
## executable, and then have dependencies on witness-emacs rather than
## bootstrap-emacs, but that lead to problems in parallel builds (because
## witness-emacs needed to be free from dependencies (to avoid rebuilding
## it), so it was compiled in parallel, leading typically to having 2
## processes dumping bootstrap-emacs at the same time).
## So instead, we replace the witness-emacs dependencies by conditional
## bootstrap-dependencies (via $(BOOTSTRAPEMACS)). Of course, since we do
## not want to rely on GNU Make features, we have to rely on an external
## script to do the conditional part of the dependency
## (i.e. see the $(SUBDIR) rule ../Makefile.in).
.SUFFIXES: .elc .el
## These suffix rules do not allow additional dependencies, sadly, so
## instead of adding a $(BOOTSTRAPEMACS) dependency here, we add it
## separately below.
## With GNU Make, we would just say "%.el : %.elc $(BOOTSTRAPEMACS)"
.el.elc:
@cd ../lisp; $(MAKE) $(MFLAGS) compile-onefile \
THEFILE=$< EMACS=$(bootstrap_exe)
## Since the .el.elc rule cannot specify an extra dependency, we do it here.
$(lisp): $(BOOTSTRAPEMACS)
## VCSWITNESS points to the file that holds info about the current checkout.
## We use it as a heuristic to decide when to rebuild loaddefs.el.
