- Update to glibc 2.24
  * The minimum Linux kernel version that this version of the GNU C Library
    can be used with is 3.2
  * The pap_AN locale has been deleted
  * The readdir_r and readdir64_r functions have been deprecated
  * The type `union wait' has been removed
  * A new NSS action is added to facilitate large distributed system
    administration
  * The deprecated __malloc_initialize_hook variable has been removed from
    the API
  * The long unused localedef --old-style option has been removed
  * nextupl, nextup, nextupf, nextdownl, nextdown and nextdownf are added
    to libm
  * An unnecessary stack copy in _nss_dns_getnetbyname_r was removed
    (CVE-2016-3075)
  * Previously, getaddrinfo copied large amounts of address data to the
    stack, even after the fix for CVE-2013-4458 has been applied,
    potentially resulting in a stack overflow.  getaddrinfo now uses a
    heap allocation instead (CVE-2016-3706)
  * The glob function suffered from a stack-based buffer overflow when it
    was called with the GLOB_ALTDIRFUNC flag and encountered a long file
    name (CVE-2016-1234)
  * The Sun RPC UDP client could exhaust all available stack space when
    flooded with crafted ICMP and UDP messages (CVE-2016-4429)
  * The IPv6 name server management code in libresolv could result in a
    memory leak for each thread which is created, performs a failing
    naming lookup, and exits (CVE-2016-5417)
- setcontext-unwind-info.patch: Add EABI unwind info for setcontext on arm
- Removed patches:

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.

callback function gl_readdir.
* posix/glob.c (NAMELEN, CONVERT_D_NAMLEN): Remove.
(CONVERT_DIRENT_DIRENT64): Use strcpy instead of memcpy.

@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.

-------------------------------------------------------------------
Tue Aug 2 13:55:44 UTC 2016 - schwab@suse.de
- Update to glibc 2.24
* The minimum Linux kernel version that this version of the GNU C Library
can be used with is 3.2
* The pap_AN locale has been deleted
* The readdir_r and readdir64_r functions have been deprecated
* The type `union wait' has been removed
* A new NSS action is added to facilitate large distributed system
administration
* The deprecated __malloc_initialize_hook variable has been removed from
the API
* The long unused localedef --old-style option has been removed
* nextupl, nextup, nextupf, nextdownl, nextdown and nextdownf are added
to libm
* An unnecessary stack copy in _nss_dns_getnetbyname_r was removed
(CVE-2016-3075)
* Previously, getaddrinfo copied large amounts of address data to the
stack, even after the fix for CVE-2013-4458 has been applied,
potentially resulting in a stack overflow. getaddrinfo now uses a
heap allocation instead (CVE-2016-3706)
* The glob function suffered from a stack-based buffer overflow when it
was called with the GLOB_ALTDIRFUNC flag and encountered a long file
name (CVE-2016-1234)
* The Sun RPC UDP client could exhaust all available stack space when
flooded with crafted ICMP and UDP messages (CVE-2016-4429)
* The IPv6 name server management code in libresolv could result in a
memory leak for each thread which is created, performs a failing
naming lookup, and exits (CVE-2016-5417)

- Update to glibc 2.24
* The minimum Linux kernel version that this version of the GNU C Library
can be used with is 3.2
* The pap_AN locale has been deleted
* The readdir_r and readdir64_r functions have been deprecated
* The type `union wait' has been removed
* A new NSS action is added to facilitate large distributed system
administration
* The deprecated __malloc_initialize_hook variable has been removed from
the API
* The long unused localedef --old-style option has been removed
* nextupl, nextup, nextupf, nextdownl, nextdown and nextdownf are added
to libm
* An unnecessary stack copy in _nss_dns_getnetbyname_r was removed
(CVE-2016-3075)
* Previously, getaddrinfo copied large amounts of address data to the
stack, even after the fix for CVE-2013-4458 has been applied,
potentially resulting in a stack overflow. getaddrinfo now uses a
heap allocation instead (CVE-2016-3706)
* The glob function suffered from a stack-based buffer overflow when it
was called with the GLOB_ALTDIRFUNC flag and encountered a long file
name (CVE-2016-1234)
* The Sun RPC UDP client could exhaust all available stack space when
flooded with crafted ICMP and UDP messages (CVE-2016-4429)
* The IPv6 name server management code in libresolv could result in a
memory leak for each thread which is created, performs a failing
naming lookup, and exits (CVE-2016-5417)
