 Subject: [PATCH] Create feature-test in source directory
@ -6,27 +6,16 @@ Subject: [PATCH] Create feature-test in source directory
 Feature-test tool is used in system tests to test compiled in changes.
 Because we build more variants of named with different configuration,
 compile feature-test for each of them this way.

-Subject: [PATCH] Test case insensitive matching in isc_ht hash table
- implementation
-
-The case insensitive matching in isc_ht was basically completely broken
-as only the hashvalue computation was case insensitive, but the key
-comparison was always case sensitive.
-
-Import only test part from upstream.
-

-Subject: [PATCH] Add a system test for mixed-case data for the same owner
-
-We were missing a test where a single owner name would have multiple
-types with a different case.  The generated RRSIGs and NSEC records will
-then have different case than the signed records and message parser have
-to cope with that and treat everything as the same owner.

-Subject: [PATCH] Fix map offsets in the "masterformat" system test
-
-The "masterformat" system test attempts to check named-checkzone
-behavior when it is fed corrupt map-format zone files.  However, despite
-the RBTDB and RBT structures having evolved over the years, the offsets
-at which a valid map-format zone file is malformed by the "masterformat"
-test have not been updated accordingly, causing the relevant checks to
-introduce a different type of corruption than they were originally meant
-to cause:
-
-  - the "bad node header" check originally mangled the 'type' member of
-    the rdatasetheader_t structure for cname.example.nil,
-
-  - the "bad node data" check originally mangled the 'serial' and
-    'rdh_ttl' members of the rdatasetheader_t structure for
-    aaaa.example.nil.
-
-Update the offsets at which the map-format zone file is malformed at by
-the "masterformat" system test so that the relevant checks fulfill their
-original purpose again.

-Subject: [PATCH] Add a limit to the number of RR types for single name
-
-Previously, the number of RR types for a single owner name was limited
-only by the maximum number of the types (64k).  As the data structure
-that holds the RR types for the database node is just a linked list, and
-there are places where we just walk through the whole list (again and
-again), adding a large number of RR types for a single owner named with
-would slow down processing of such name (database node).
-
-Add a configurable limit to cap the number of the RR types for a single
-owner.  This is enforced at the database (rbtdb, qpzone, qpcache) level
-and configured with new max-types-per-name configuration option that
-can be configured globally, per-view and per-zone.
-
-(cherry picked from commit 00d16211d6368b99f070c1182d8c76b3798ca1db)
-(cherry picked from commit 89f1779bc28b27adbd00325b974ede7a683f8632)
-
-fix a memory leak that could occur when signing
-
-when signatures were not added because of too many types already
-existing at a node, the diff was not being cleaned up; this led to
-a memory leak being reported at shutdown.
-
-(cherry picked from commit 2825bdb1ae5be801e7ed603ba2455ed9a308f1f7)
-(cherry picked from commit a080317de0efb7f6ffa12415a863729d416007d5)
-
-Be smarter about refusing to add many RR types to the database
-
-Instead of outright refusing to add new RR types to the cache, be a bit
-smarter:
-
-1. If the new header type is in our priority list, we always add either
-   positive or negative entry at the beginning of the list.
-
-2. If the new header type is negative entry, and we are over the limit,
-   we mark it as ancient immediately, so it gets evicted from the cache
-   as soon as possible.
-
-3. Otherwise add the new header after the priority headers (or at the
-   head of the list).
-
-4. If we are over the limit, evict the last entry on the normal header
-   list.
-
-(cherry picked from commit 57cd34441a1b4ecc9874a4a106c2c95b8d7a3120)
-(cherry picked from commit 92a680a3ef708281267e4fd7b1e62b57c929447b)
-
-Log error when update fails
-
-The new "too many records" error can make an update fail without the
-error being logged. This commit fixes that.
-

-Subject: [PATCH] Add a limit to the number of RRs in RRSets
-
-Previously, the number of RRs in the RRSets were internally unlimited.
-As the data structure that holds the RRs is just a linked list, and
-there are places where we just walk through all of the RRs, adding an
-RRSet with huge number of RRs inside would slow down processing of said
-RRSets.
-
-The fix for end-of-life branches make the limit compile-time only for
-simplicity and the limit can be changed at the compile time by adding
-following define to CFLAGS:
-
-    -DDNS_RDATASET_MAX_RECORDS=<limit>
-
-(cherry picked from commit c5c4d00c38530390c9e1ae4c98b65fbbadfe9e5e)
-(cherry picked from commit fdabf4b9570a60688f9f7d1e88d885f7a3718bca)
-
-Add a limit to the number of RR types for single name
-
-Previously, the number of RR types for a single owner name was limited
-only by the maximum number of the types (64k).  As the data structure
-that holds the RR types for the database node is just a linked list, and
-there are places where we just walk through the whole list (again and
-again), adding a large number of RR types for a single owner named with
-would slow down processing of such name (database node).
-
-Add a hard-coded limit (100) to cap the number of the RR types for a single
-owner.  The limit can be changed at the compile time by adding following
-define to CFLAGS:
-
-    -DDNS_RBTDB_MAX_RTYPES=<limit>
-
-(cherry picked from commit dfcadc2085c8844b5836aff2b5ea51fb60c34868)
-
-Optimize the slabheader placement for certain RRTypes
-
-Mark the infrastructure RRTypes as "priority" types and place them at
-the beginning of the rdataslab header data graph.  The non-priority
-types either go right after the priority types (if any).
-
-(cherry picked from commit 3ac482be7fd058d284e89873021339579fad0615)
-(cherry picked from commit 8ef414a7f38a04cfc11df44adaedaf3126fa3878)
-
-Expand the list of the priority types
-
-Add HTTPS, SVCB, SRV, PTR, NAPTR, DNSKEY and TXT records to the list of
-the priority types that are put at the beginning of the slabheader list
-for faster access and to avoid eviction when there are more types than
-the max-types-per-name limit.
-
-(cherry picked from commit b27c6bcce894786a8e082eafd59eccbf6f2731cb)
-(cherry picked from commit d56d2a32b861e81c2aaaabd309c4c58b629ede32)
-
-Make the resolver qtype ANY test order agnostic
-
-Instead of relying on a specific order of the RR types in the databases
-pick the first RR type as returned from the cache.
-
-(cherry picked from commit 58f660cf2b800963fa649bc9823a626009db3a7e)
-(cherry picked from commit c5ebda6deb0997dc520b26fa0639891459de5cb6)
-
-Be smarter about refusing to add many RR types to the database
-
-Instead of outright refusing to add new RR types to the cache, be a bit
-smarter:
-
-1. If the new header type is in our priority list, we always add either
-   positive or negative entry at the beginning of the list.
-
-2. If the new header type is negative entry, and we are over the limit,
-   we mark it as ancient immediately, so it gets evicted from the cache
-   as soon as possible.
-
-3. Otherwise add the new header after the priority headers (or at the
-   head of the list).
-
-4. If we are over the limit, evict the last entry on the normal header
-   list.

-Subject: [PATCH] Downstream specific changes related to KeyTrap
-
-Fix for CVE-2023-50387 introduced new additional thread. But because
-isc_hp functions were removed from later bind 9.16 release, their
-changes did not contain increase of hazard pointers max thread limit.
-To prevent obscure memory corruption increase thread max size.
-
-In addition place at least few INSISTs to check this is catched before
-random memory overwrites begins. It would be quite difficult to track
-without any check.

-Subject: [PATCH] Define variants to empty values
-
-DNSSEC_VARIANT and NAMED_VARIANT are special Red Hat modifications to
-allow testing or alternative rebuilds, with support for pkcs11 or sdb.
-But undefined value breaks some tests, so define them to empty values.
-That means normal build variant.
-
-Required to pass upstream test suite cds test correctly.
