From 881e3b47a17d7d0b3687ef26d782fc3281a8faa3 Mon Sep 17 00:00:00 2001

Subject: [PATCH 1/7] s3:libads: prefer ENCTYPE_AES256_CTS_HMAC_SHA1_96 in
ads_keytab_add_entry()
This is currently not critical as we only use keytabs
only as acceptor, but in future we'll also use them
for kinit() and there we should prefer the newest type.

Use the known ip address of the ldap server to open the connection and
initialize the ldap session with ldap_init_fd().
This avoid unnecessary DNS lookups which might block or prevent the
successful connection.

Subject: [PATCH 1/7] s3: libsmb: Info level SMB2_FIND_ID_BOTH_DIRECTORY_INFO
encodes attibutes as a uint32, not a uint8.
Fix the SMB2 parsing code.
Cast to a uint16_t for now after pulling the information
as finfo->mode is currently only 16 bits.
We will need this to detect FILE_ATTRIBUTE_REPARSE_POINT in a later commit.

do for a released stream.
Remove the knownfail.d/msdfs-attr file.

Subject: [PATCH 1/2] winbind: Add test for lookuprids cache problem
When reading entries from gencache, wb_cache_rids_to_names() can
return STATUS_SOME_UNMAPPED, which _wbint_LookupRids() does not handle
correctly.
This test enforces this situation by filling gencache with one wbinfo
-R and then erasing the winbindd_cache.tdb. This forces winbind to
enter the domain helper process, which will then read from gencache
filled with the previous wbinfo -R.
Without having the entries cached this does not happen because
wb_cache_rids_to_names() via the do_query: path calls deep inside
calls dcerpc_lsa_lookup_sids_noalloc(), which hides the
STATUS_SOME_UNMAPPED that came in as lsa_LookupSids result value.

Subject: [PATCH 1/2] s3:lib:tls: Use better priority lists for modern GnuTLS
We should use the default priority list. That is a good practice,
because TLS protocol hardening and phasing out of legacy algorithms,
is easier to co-ordinate when happens at a single place. See crypto
policies of Fedora.
