bind/bind-9.16-CVE-2024-1737-types.patch
Petr Menšík 45d01dade1 [9.16] chg: usr: Backport max-types-per-name to BIND 9.16 
This aligns the fix for large number of RRs in RRSet with 9.18 and up
by backporting to `max-records-per-type` configuration option to
BIND 9.16.

Merge branch 'ondrej/max-types-per-rr-backport-9.16' into 'bind-9.16'

See merge request isc-projects/bind9!9178

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.
(cherry picked from commit 558923e5405894cf976d102f0d246a28bdbb400c)
(cherry picked from commit d72adf4b927d83a2a0ff8e431b911ec1df7aeb88)
