Sorry, I looked wrong place. It is balloon_final which assumes user provided RESULT is aligned, which is wrong.

I think that this patch should not be needed, if our implementation of _gcry_private_malloc is not buggy (ensuring same alignment condition as system malloc does).
I just realized that it is buggy unfortunately, so, I'm opening a task for that.

Tested on a big endian machine.

FYI: When you have a problem with pinentry, possible workaround is using gpg with --pinentry-mode=loopback, which redirects pinentry queries to the caller (instead of invoking pinentry session).

Thank you for the debug information.

Done by rGc8cd66ae7e60: m4: Update our library m4 files from master.

The change of pinentry-tty rP7f7fd8bcfd74: tty: Fix error return paths and its resource leaks. fixes SEGV, but the problem of your case is that access to the device file (/dev/pts/2 in the case of your log with pinentry-tty) failed.

Thank you for your debugging.

Strange. pinentry-tty has no place to report ENOENT. I wonder if you notified gpg-agent when you change the config (like gpgconf --reload gpg-agent).

The string 'Pinentry' is a module name, which is defined in libgpg-error.
It means, the error source is pinentry.

Pushed the change in rE433aba9e778e: build,tests: Fix detection of have_lock_optimization..

@marv Thank you for your report.

Pushed rC254fb14044cf: kdf: Change new KDF API.

@jukivili , thank you for your comment.

Thank you, applied both of two patches.

Thanks, fixed.

Test cases are recovered in rC535a4d345872: fips: Recover test cases for selftest, add skipping in FIPS mode..

Unfortunately, gdb session log and ktrace log don't have enough information to locate the cause/problem.

Sorry, it's my misunderstanding.
_gcry_fips_run_selftest can be run by GCRYCTL_SELFTEST.
I was confused by the function name. Perhaps, it is good to change the name of function to _gcry_run_selftest.

@werner Those removed tests are selftests which are only invoked by FIPS mode for its requirement of selftests.

Pushed the change in rC76aad97dd312: fips: Reject shorter key for HMAC in FIPS mode..

And we need to fix selftest for shorter keys.

@pmgdeb : IIUC, what we need is:

diff --git a/cipher/md.c b/cipher/md.c

Thank you, applied.

Thank you, applied.
Also, add another change.
