Add 64 bit time support on legacy ABIs |

Message

Adhemerval Zanella March 5, 2021, 8:14 p.m. UTC

  This patchset add support for 64 bit time on ABIs which only support
32 bit time.  It is done through a new build flags, _TIME_BITS=64,
which is supported only when Long File Support is also used
(_FILE_OFFSET_BITS=64).  The new flag redefine the required structures
and redirected the required symbols to newer exported ones.

However, different then LFS support, the new 64 bit time_t symbols
are only exported for the ABI that require them.  ABIs that provides
64 bit time as the default ABI as unaffected.

On Linux, to fully support 64 bit time_t it requires a minimum of
kernel v5.1 due the newer syscalls.

To make the patch review easier, it is divided in 5 subparts:

  1. Patches from 01/52 to 14/52 are newer tests and infrastructure
     changes that are independent of 64 bit time support.

  2. Patches from 15/52 to 23/52 add the 64 bit time support on
     utmp/utmpx/lastlog and it affects *all* the ABIs with the
     exception of s390.

  3. Patches from 24/52 to 41/52 are the one that adjust the exported
     API, add some specific newer symbols (glob, ftw, and fts) and
     enable the _TIME_BITS on the installed headers.

  4. Patches from 42/52 to 44/52 enables basic test coverage.  Although
     it does not cover all the newer symbol redirection, the idea is to
     use Lukasz patches and newer tests to cover all the symbols for
     2.34 release.

  5. Patches from 45/52 to 52/52 make glibc itself to use the newer
     64 bit symbol internally and on installed programs.

I checked for i686-linux-gnu running on a x86_64 5.4 kernel,
powerpc-linux-gnu running on ppc64 5.10 kernel, and on
arm-linux-gnueabihf running on arm64 4.12.13 kernel.  As expected,
the arm shows some tests failures due the missing kernel support:

I'd expect tests on an older kernel to be UNSUPPORTED, not FAIL.

More precisely: tests of times that can be represented in 32 bits, but 
using the 64-bit interfaces, should be PASS, and tests of times that can't 
be represented in 64 bits should be UNSUPPORTED as long as those are in a 
separate testcase from the tests of times that can be represented in 32 
bits.  If in the same testcase, FAIL seems the worst result, since it's 
not indicating any bug in glibc.

There are still floating some patches, which would allow changing time
on target machines (usually in VM). I hope to get them pulled soon.

Big thanks for preparing this patch set - this is a huge step to have
64 bit time_t support on ports with __TIMESIZE != 64 and __WORDSIZE ==
32

The problem is how to recognize a glibc failure over, a kernel failure,
and a kernel missing support.  I think we add a syscall probe for 64-bit
time_t syscall and assume a kernel without support for ENOSYS and act 
accordingly.
