| 2019-12-08 | fix null pointer dereference in setitimer time32 compat shim•••this interface permits a null pointer for where to store the old
itimerval being replaced. an early version of the time32 compat shim
code had corresponding bugs for lots of functions; apparently
setitimer was overlooked when fixing them.

| 2019-12-07 | arm: avoid conditional branch to PLT in sigsetjmp•••The R_ARM_THM_JUMP19 relocation type generated for the original code
when targeting Thumb 2 is not supported by the gold linker.

| 2019-12-07 | riscv64: fix fesetenv(FE_DFL_ENV) crash•••When FE_DFL_ENV is passed to fesetenv(), the very first instruction
lw t1, 0(a0) will fail since a0 is -1.

for my new name.

| 2019-11-05 | fix build regression on mips64 due to endian.h removal•••commit 4d3a162d001a93edd285fb6603a883c30ae553ba overlooked that the
mips64 reloc.h dependent on endian.h not only for setting the ABI ldso
name to match the byte order, but also for use of the byte swapping
macros. they are needed to override R_TYPE, R_SYM, and R_INFO, to
compensate for a mips "quirk" of always using big endian order for
symbol references in relocations.
part of that commit canot be reverted because the original code was
wrong: it's invalid to define _GNU_SOURCE or any feature test macro
in reloc.h, or anywhere except at the top of a source file. however,
thanks to commit 316730cdc7a330cddf288b4e5c1de5daa64e19f4, the feature
test macro is no longer needed to access the endian-swapping macros,
so simply bringing back the #include directive suffices.

| 2019-11-04 | fix failure to build time32 compat shims with out-of-tree builds•••commit de90f38e3b105802655d19d965d66335d25d59ef omitted $(srcdir) from
the makefile include pathname it added. since the include directive
was prefixed with - to make it optional (for archs that don't use it),
the failure to find arch/$(ARCH)/arch.mak was silent.

| 2019-11-03 | fix time64 link regression of dlsym stub for static-linked programs•••in commit 22daaea39f1cc5f7391f0a5cd84576ffb58c2860, the
__dlsym_redir_time64 function providing the backend for __dlsym_time64
was defined only in the dynamic linker, and thus was undefined when
static linking a program referencing dlsym. use the same stub_dlsym
definition that provides __dlsym (the non-redirecting backend) for
static linked programs to provide it, conditional on _REDIR_TIME64.

| 2019-11-02 | move time_t and suseconds_t definitions to common alltypes.h.in•••now that all 32-bit archs have 64-bit time_t (and suseconds_t), the
arch-provided _Int64 macro (long or long long, as appropriate) can be
used to define them, and arch-specific definitions are no longer
needed.

| 2019-11-02 | move time64 ioctl numbers to generic bits/ioctl.h•••now that all 32-bit archs have 64-bit time types, the values for the
time-related ioctls can be shared. the mechanism for this is an
arch/generic version of the bits header. archs which don't use the
generic header still need to duplicate the definitions.
x32, which does not use the new time64 values of the macros, already
has its own overrides, so this commit does not affect it.

| 2019-11-02 | move time64 socket options from arch bits to top-level sys/socket.h•••now that all 32-bit archs have 64-bit time types, the values for the
time-related socket option macros can be treated as universal for
32-bit archs. the sys/socket.h mechanism for this predates
arch/generic and is instead in the top-level header.
x32, which does not use the new time64 values of the macros, already
has its own overrides, so this commit does not affect it.

| 2019-11-02 | switch all existing 32-bit archs to 64-bit time_t•••this commit preserves ABI fully for existing interface boundaries
between libc and libc consumers (applications or libraries), by
retaining existing symbol names for the legacy 32-bit interfaces and
redirecting sources compiled against the new headers to alternate
symbol names. this does not necessarily, however, preserve the
pairwise ABI of libc consumers with one another; where they use
time_t-derived types in their interfaces with one another, it may be
necessary to synchronize updates with each other.
the intent is that ABI resulting from this commit already be stable
and permanent, but it will not be officially so until a release is
made. changes to some header-defined types that do not play any role
in the ABI between libc and its consumers may still be subject to
change.
mechanically, the changes made by this commit for each 32-bit arch are
as follows:
- _REDIR_TIME64 is defined to activate the symbol redirections in
public headers
- COMPAT_SRC_DIRS is defined in arch.mak to activate build of ABI
compat shims to serve as definitions for the original symbol names
- time_t and suseconds_t definitions are changed to long long (64-bit)
- IPC_STAT definition is changed to add the IPC_TIME64 bit (0x100),
triggering conversion of semid_ds, shmid_ds, and msqid_ds split
low/high time bits into new time_t members
- structs semid_ds, shmid_ds, msqid_ds, and stat are modified to add
new 64-bit time_t/timespec members at the end, maintaining existing
layout of other members.
- socket options (SO_*) and ioctl (sockios) command macros are
redefined to use the kernel's "_NEW" values.
in addition, on archs where vdso clock_gettime is used, the
VDSO_CGT_SYM macro definition in syscall_arch.h is changed to use a
new time64 vdso function if available, and a new VDSO_CGT32_SYM macro
is added for use as fallback on kernels lacking time64.
