Commit Message

Florian Weimer March 16, 2021, 5:29 p.m. UTC 
It's necessary to stub out __libc_disable_asynccancel and
__libc_enable_asynccancel via rtld-stubbed-symbols because the new
direct references to the unwinder result in symbol conflicts when the
rtld exception handling from libc is linked in during the construction
of librtld.map.

unwind-forcedunwind.c is merged into unwind-resume.c.  libc now needs
the functions that were previously only used in libpthread.

The GLIBC_PRIVATE exports of __libc_longjmp and __libc_siglongjmp are
no longer needed, so switch them to hidden symbols.

The symbol __pthread_unwind_next has been moved using
scripts/move-symbol-to-libc.py.

From where exactly these come from? The *assynccancel should not be
generated for rtld-* objects.

LGTM, thanks.

I think what happens is this: The libc.so objects that are used as a
starting point have them, so the reducer tries to link in those symbols,
and that fails with symbol conflicts.

The error message is slightly different because the function name is
different.  __libc_fatal doesn't do format processing, so it has to be
one literal.  So there isn't that much commonality.

Thanks for the review.

Right, but why doesn't it happen with other symbols that might be
pulled as well? It not a blocker, but I am trying to understand why
we are seeing this behavior with this change.

Ah, the explanation is quite trivial: We used to have a forwarder for
__pthread_unwind, and that acted as a firewall for the rtld symbol set
discovery.  Now the forwarder is gone, so the implementation of
__pthread_unwind starts to matter.

Maybe I should stub out __pthread_unwind instead?  But doing it for the
cancellation feels more natural.

Thanks,
Florian

The cancellation stub are fine, the long term goal is to remove them
anyway.
