(nve_set): Add arg PK. Change the caller.
* agent/findkey.c (agent_write_private_key): Update only if modified.
--
This helps software which uses a file system watcher to track changes
to private keys. In particular smartcard triggered changes are a
problem for such software because this may at worst trigger another
smartcard read.

This allows reading the certificates from my sample cards. Signing
does not yet work; I need to do get some I/O traces using other
software. The basic support for AET cards shut still work but I have
not found my AET card.
* g10/call-agent.c (agent_get_passphrase): Call
assuan_begin_confidential and assuan_end_confidential.
* sm/call-agent.c (gpgsm_agent_ask_passphrase): Ditto.
--
GnuPG-bug-id: 6654
The drawback of this solution is that we don't see any IPC lines from
the assuan_transact. Everything else would require larger changes to
libassuan.
* sm/encrypt.c (gpgsm_encrypt): Unify use of RC and ERR.
* sm/sign.c (gpgsm_sign): ditto.
--
Initially we didn't used the gpg_error_t thingy and while migrating
we sometimes used RC and ERR for tracking the error. This is pretty
error prone and thus we better remove it (after 20 years).
* common/mischelp.c (timegm): Move to ...
* common/gettime.c (timegm): here. On Windows use timegm_u32.
(timegm_u32): New.
(isotime2epoch): Factor code out to ...
(isotime_make_tm): new helper.
(isotime2epoch_u64): New.
(_win32_timegm): Remove duplicated code.
(parse_timestamp): Use of timegm.
(scan_isodatestr): Fallback to isotime2epoch_u64.
--
This mainly helps on 32 bit Windows. For Unix we assume everyone is
using 64 bit or shall wait until the libc hackers finally provide a
time64_t.

* sm/minip12.c: Factor parsing code out to ...
* common/tlv-parser.c: new. Extend function names and provide a few
extra functions.

(p12_parse): Ditto.
* sm/minip12.c (decrypt_block): Strip the padding.
(tlv_expect_top_sequence): Remove. Replace callers by
tlv_expect_sequence.
* tests/cms/samplekeys/t6752-ov-user-ff.p12: New sample key.
* tests/cms/samplekeys/Description-p12: Add its description
--
This patch improves the BER parser by simplifying it. Now tlv_next
pops off and thus closes all containers regardless on whether they are
length bounded or ndef. tlv_set_pending is now always used to undo
the effect of a tlv_next in a loop condition which was terminated by a
nesting level change.
Instead of using the length as seen in the decrypted container we now
remove the padding and let the BER parser do its work. This might
have a negative effect on pkcs#12 objects which are not correctly
padded but we don't have any example of such broken objects.
GnuPG-bug-id: 6752
* m4/autobuild.m4 (AB_INIT): Add username.
--
The old autobuild diagnostics show up in build logs. What they are
missing is an information on the user who triggered a build. EMAIL is
a common thing to denote the actual user using a service account.
* g10/keygen.c (parse_expire_string_with_ct): Use new function
scan_secondsstr.
(parse_creation_string): Ditto.
--
Noet that we cap the seconds at the year 2106.
GnuPG-bug-id: 6736
* sm/minip12.c (_tlv_push): Handle NDEF more correctly.
(tlv_expect_octet_string): Do not bail out on NDEF.
(dump_tag_info): Print some more infos.
--
We do not have a complete test case for this. We need to further
analyze T6752 to see what Mozilla is doing here. In any case with
this patch we get a bit further and don't bail out at the ndef.

(parse_bag_encrypted_data): Parse the optional prf part and get the
hmac algorithm.

(p12_build): Pass SHA1 for digest_algo.
* sm/t-minip12.c (run_one_test): Print failed values in verbose mode.

This supports the modern algorithms, i.e. using SHA256 for the KDF
which is the default in openssl unless the -legacy option is used.

This bug was exhibited by importing a gpgsm exported EC certificate.
We use an extra test instead of retrying to allow retruning an error
from malloc failure. And well, for easier reading of the code.

* common/dotlock.c (next_wait_interval): New.
(dotlock_take_unix): Use new function.
(dotlock_take_w32): Ditto.
--
In particular when using a dotlock file for protecting the spawning
and several processes try to spawn the agent or another component, we
often run into long delays. The solution is to is to exponential
backoff and also to reduce the initial delay from 50ms to 4ms. We
further limit the maximum wait period to about 2 seconds and then
repeat at intervals of 512, 1024 and 2048ms. In the wait-forever case
we add a small random value to have different intervals per process.
GnuPG-bug-id: 3380
For testing this code snippet in the spawning function might be
useful:
const char *s;
if ((s=getenv("hold_gpg_file")))
while (!gnupg_access (s, F_OK))
gnupg_sleep (1);
* dirmngr/http.c (enum auth_negotiate_states): New.
(struct proxy_info_s): Add new fields.
(release_proxy_info): Free Windows stuff.
(proxy_get_token): New. Implemented only for Windows for now.
(run_proxy_connect): Add support for auth method Negotiation.
(store_header): Keep some header lines separate.
--
The code does something but I have not yet been able to test it due
to problems setting up Squid with AD authentication. As of now it
will respond with a failure but that should not be worse than not to
implement Negotiation.
Supporting Negotiation using GSS for Unix should eventually also be
done.

* common/b64dec.c (b64decode): New.

(main): Default to run the new test.
* common/Makefile.am (module_maint_tests): Move t-b64 to ...
(module_tests): here.
--
Sometimes we have a short base64 encoded string we need todecode.
This function makes it simpler.
License change of the test module justified because I am the single
author of the code.
* dirmngr/http.c (cookie_s): Add fields pending, up_to_empty_line,
last_was_lf, and last_was_lfcr.
(http_context_s): Add field keep-alive.
(http_wait_response): Set up_to_empty_line. Take care of keep_alive
flag.
(coookie_read): Implement detection of empty lines.
(cookie_write): Free the pending buffer.
--
The problem we fix here is that we already buffered stuff beyond the
empty line which marks the start of the content-length counting. Thus
we tried to wait for more bytes despite that everything had already
been read. This bug might have showed up more often in the real world
since the we changed the BUFSIZ on Windows from 512 byte to 8k. It
also depends on the length of the headers and whether the server
closed the connection so that we ignored the Content-Length.
The bug was introduced earlier than 2010 and could have the effect
that a connection got stuck until the network layer timed out.
Note that the keep-alive parts of the patch are not yet used.
* dirmngr/http.c: Remove gnutls version specific code.
(send_request): Factor some code out to ...
(run_proxy_connect): new.
(mk_proxy_request): new.
(mk_std_request): new.
* configure.ac (NEED_GNUTLS_VERSION): Require 3.2.
--
This patch is to factor out some code and also to remove support for
legacy gnutls versions. Note that gnutls 3.2 was released 10 years
ago.
