(send_dg): Initialize *resplen2 after reopen failure. Call

2016-04-14 Florian Weimer <fweimer@redhat.com>
Remove malloc hooks from fork handler. They are no longer needed
because malloc runs right before fork, and no malloc calls from
other fork handlers are not possible anymore.
* malloc/malloc.c (malloc_atfork, free_atfork): Remove
declarations.
* malloc/arena.c (save_malloc_hook, save_free_hook, save_arena)
(ATFORK_ARENA_PTR, malloc_atfork, free_atfork)
(atfork_recursive_cntr): Remove.
(__malloc_fork_lock_parent): Do not override malloc hooks and
thread_arena.
(__malloc_fork_unlock_parent): Do not restore malloc hooks and
thread_arena.
(__malloc_fork_unlock_child): Do not restore malloc hooks. Use
thread_arena instead of save_arena.

glob: Simplify and document the interface for the GLOB_ALTDIRFUNC
callback function gl_readdir.
* posix/glob.c (NAMELEN, CONVERT_D_NAMLEN): Remove.
(CONVERT_DIRENT_DIRENT64): Use strcpy instead of memcpy.
(glob_in_dir): Remove len. Use strdup instead of malloc and
memcpy to copy the name.
* manual/pattern.texi (Calling Glob): Document requirements for
implementations of the gl_readdir callback function.
* manual/examples/mkdirent.c: New example.
* posix/bug-glob2.c (my_readdir): Set d_ino to 1 unconditionally,
per the manual guidance.
* posix/tst-gnuglob.c (my_readdir): Likewise.

@code{GLOB_ALTDIRFUNC} bit is set in the flag parameter. The type of
this field is @w{@code{struct dirent *(*) (void *)}}.
-This is a GNU extension.
+An implementation of @code{gl_readdir} needs to initialize the following
+members of the @code{struct dirent} object:
+
+@table @code
+@item d_type
+This member should be set to the file type of the entry if it is known.
+Otherwise, the value @code{DT_UNKNOWN} can be used. The @code{glob}
+function may use the specified file type to avoid callbacks in cases
+where the file type indicates that the data is not required.
+
+@item d_ino
+This member needs to be non-zero, otherwise @code{glob} may skip the
+current entry and call the @code{gl_readdir} callback function again to
+retrieve another entry.
+
+@item d_name
+This member must be set to the name of the entry. It must be
+null-terminated.
+@end table
+
+The example below shows how to allocate a @code{struct dirent} object
+containing a given name.
+
+@smallexample
+@include mkdirent.c.texi
+@end smallexample
+
+The @code{glob} function reads the @code{struct dirent} members listed
+above and makes a copy of the file name in the @code{d_name} member
+immediately after the @code{gl_readdir} callback function returns.
+Future invocations of any of the callback functions may dealloacte or
+reuse the buffer. It is the responsibility of the caller of the
+@code{glob} function to allocate and deallocate the buffer, around the
+call to @code{glob} or using the callback functions. For example, an
+application could allocate the buffer in the @code{gl_readdir} callback
+function, and deallocate it in the @code{gl_closedir} callback function.
+
+The @code{gl_readdir} member is a GNU extension.

[BZ #19779]
CVE-2016-1234
Avoid copying names of directory entries.
* posix/glob.c (DIRENT_MUST_BE, DIRENT_MIGHT_BE_SYMLINK)
(DIRENT_MIGHT_BE_DIR, CONVERT_D_INO, CONVERT_D_TYPE)
(CONVERT_DIRENT_DIRENT64, REAL_DIR_ENTRY): Remove macros.
(struct readdir_result): New type.
(D_TYPE_TO_RESULT, D_INO_TO_RESULT, READDIR_RESULT_INITIALIZER)
(GL_READDIR): New macros.
(readdir_result_might_be_symlink, readdir_result_might_be_dir)
(convert_dirent, convert_dirent64): New functions.
(glob_in_dir): Use struct readdir_result. Call convert_dirent or
convert_dirent64. Adjust references to the readdir result.
* sysdeps/unix/sysv/linux/i386/glob64.c:
(convert_dirent, GL_READDIR): Redefine for second file inclusion.
* posix/bug-glob2.c (LONG_NAME): Define.
(filesystem): Add LONG_NAME.
(my_DIR): Increase the size of room_for_dirent.
