  This is part of the libpthread removal project:

  <https://sourceware.org/ml/libc-alpha/2019-10/msg00080.html>

For ia64-linux-gnu, the sigblock was never exported from libphread.

Checked with a build against all affected ABIs.

This change is not fully compatible: Newly-linked programs may incur
lazy binding failures on older glibc versions because pthread_sigmask
is not present in libc.so.6.

In other cases, we have added a compat symbol and a new symbol
version.

But backward compatibility is not a fully support scenario. Do we
really need to handle such cases for the libpthread removal
project?

So far, our approach to symbol versioning has been that if the
application (or DSO) loads, it will not fail later due to a missing
symbol.  Some RPM-based distributions have no other mechanism to
ensure correct package dependencies.

Yes, but my understanding was exactly that new loader behaviour
(f0b2132b3524) will prevent the failure for this specific case.
What I am getting is we are adding this constraint due a rpm
limitation, is that correct?

No, the loader behavior change is for existing binaries linked against
an old libpthread.  It cannot handle new binaries which are not linked
against libpthread, but use pthread_sigmask.  These binaries will load
only if the process has loaded libpthread for another reason.

That's not what I am seeing in fact. Based on my patchset, I changed
tst-sigisemptyset.c to call pthread_sigmask:

$ readelf -a signal/tst-sigisemptyset | grep "(NEEDED)"
 0x0000000000000001 (NEEDED)             Shared library: [libc.so.6]

$ LD_DEBUG=all ./elf/ld-linux-x86-64.so.2 --library-path .:./math:./elf:./dlfcn:./nss:./nis:./rt:./resolv:./mathvec:./support:./crypt:./nptl signal/tst-sigisemptyset --direct
[...]
     20190:     symbol=pthread_sigmask;  lookup in file=signal/tst-sigisemptyset [0]
     20190:     symbol=pthread_sigmask;  lookup in file=./libc.so.6 [0]
[...]

And checking with maps, libpthread was not loaded.

Off course, trying to use the system loader won't work:

$ signal/tst-sigisemptyset
signal/tst-sigisemptyset: relocation error: signal/tst-sigisemptyset: symbol pthread_sigmask version GLIBC_2.2.5 not defined in file libc.so.6 with link time reference

But it is expected.  What I am missing here?

Does the test executable use lazy binding?  Is this a load-time error
or a run-time error?

Of course, there will always be an error, but the question is whether
it is a load-time error or a failure later at run time.  Our position
so far has been that glibc symbol changes will not cause lazy binding
failures (something that once had significant value, but less so with
widespread BIND_NOW usage).

It is using lazy biding (I am building with a toolchain built with 
buildmanyglibcs.py and default since there is no out-of-tree patches
the default is lazy).

Ok, I will rework the patch to force a load-time failure in such cases.

Updated patch below:

--

This is part of the libpthread removal project:

  <https://sourceware.org/ml/libc-alpha/2019-10/msg00080.html>

A new symbol is added on glibc and a compat one on libpthread
(to force loading failure instead of lazy binding one for newly
binaries with old loaders).

For ia64-linux-gnu, the sigblock was never exported from libphread.

Checked with a build against all affected ABIs.
