+Version 2.22
+
+* The following bugs are resolved with this release:
+
+ 4719, 6792, 13064, 14094, 14841, 14906, 15319, 15467, 15790, 15969, 16351,
+ 16512, 16560, 16783, 16850, 17090, 17195, 17269, 17523, 17542, 17569,
+ 17588, 17596, 17620, 17621, 17628, 17631, 17711, 17776, 17779, 17792,
+ 17836, 17912, 17916, 17930, 17932, 17944, 17949, 17964, 17965, 17967,
+ 17969, 17978, 17987, 17991, 17996, 17998, 17999, 18019, 18020, 18029,
+ 18030, 18032, 18036, 18038, 18039, 18042, 18043, 18046, 18047, 18068,
+ 18080, 18093, 18100, 18104, 18110, 18111, 18128, 18138, 18185, 18197,
+ 18206, 18210, 18211, 18247, 18287.
+
+* A buffer overflow in gethostbyname_r and related functions performing DNS
+ requests has been fixed. If the NSS functions were called with a
+ misaligned buffer, the buffer length change due to pointer alignment was
+ not taken into account. This could result in application crashes or,
+ potentially arbitrary code execution, using crafted, but syntactically
+ valid DNS responses. (CVE-2015-1781)
+
+* A powerpc and powerpc64 optimization for TLS, similar to TLS descriptors
+ for LD and GD on x86 and x86-64, has been implemented. You will need
+ binutils-2.24 or later to enable this optimization.
+
+* Character encoding and ctype tables were updated to Unicode 7.0.0, using
+ new generator scripts contributed by Pravin Satpute and Mike FABIAN (Red
+ Hat). These updates cause user visible changes, such as the fix for bug
+ 17998.

+ 17892.
+
+* CVE-2015-1472 CVE-2015-1473 Under certain conditions wscanf can allocate
+ too little memory for the to-be-scanned arguments and overflow the
+ allocated buffer. The implementation now correctly computes the required
+ buffer size when using malloc, and switches to malloc from alloca as
+ intended.
+
+* A new semaphore algorithm has been implemented in generic C code for all
+ machines. Previous custom assembly implementations of semaphore were
+ difficult to reason about or ensure that they were safe. The new version
+ of semaphore supports machines with 64-bit or 32-bit atomic operations.
+ The new semaphore algorithm is used by sem_init, sem_open, sem_post,
+ sem_wait, sem_timedwait, sem_trywait, and sem_getvalue.
+
+* Port to Altera Nios II has been contributed by Mentor Graphics.
+
+* Optimized strcpy, stpcpy, strncpy, stpncpy, strcmp, and strncmp
+ implementations for powerpc64/powerpc64le.
+ Implemented by Adhemerval Zanella (IBM).
+
+* Added support for TSX lock elision of pthread mutexes on powerpc32, powerpc64
+ and powerpc64le. This may improve lock scaling of existing programs on
+ HTM capable systems. The lock elision code is only enabled with
+ --enable-lock-elision=yes. Also, the TSX lock elision implementation for
+ powerpc will issue a transaction abort on every syscall to avoid side
+ effects being visible outside transactions.
* Optimized strcpy, stpcpy, strchrnul and strrchr implementations for
AArch64. Contributed by ARM Ltd.
* CVE-2104-7817 The wordexp function could ignore the WRDE_NOCMD flag
under certain input conditions resulting in the execution of a shell for
- command substitution when the applicaiton did not request it. The
+ command substitution when the application did not request it. The
implementation now checks WRDE_NOCMD immediately before executing the
shell and returns the error WRDE_CMDSUB as expected.
* Merged gettext 0.19.3 into the intl subdirectory. This fixes building
with newer versions of bison.
+
+* Support for MIPS o32 FPXX, FP64A and FP64 ABI Extensions.
+ The original MIPS o32 hard-float ABI requires an FPU where double-precision
+ registers overlay two consecutive single-precision registers. MIPS32R2
+ introduced a new FPU mode (FR=1) where double-precision registers extend the
+ corresponding single-precision registers which is incompatible with the
+ o32 hard-float ABI. The MIPS SIMD ASE and the MIPSR6 architecture both
+ require the use of FR=1 making a transition necessary. New o32 ABI
+ extensions enable users to migrate over time from the original o32 ABI
+ through to the updated o32 FP64 ABI. To achieve this the dynamic linker now
+ tracks the ABI of any loaded object and verifies that new objects are
+ compatible. Mode transitions will also be requested as required and
+ unsupportable objects will be rejected. The ABI checks include both soft and
+ hard float ABIs for o32, n32 and n64.
+
+ GCC 5 with GNU binutils 2.25 onwards:
+ It is strongly recommended that all o32 system libraries are built using the
+ new o32 FPXX ABI (-mfpxx) to facilitate the transition as this is compatible
+ with the original and all new o32 ABI extensions. Configure a MIPS GCC
+ compiler using --with-fp-32=xx to set this by default.
