PGSQL BIND SDB driver
|
||||
|
||||
The postgresql BIND SDB driver is of experimental status and should not be
|
||||
used for production systems.
|
||||
|
||||
Usage:
|
||||
|
||||
o Use the named_sdb process ( put ENABLE_SDB=yes in /etc/sysconfig/named )
|
||||
|
||||
o Edit your named.conf to contain a database zone, eg. :
|
||||
|
||||
zone "pgdb.net." IN {
|
||||
type master;
|
||||
database "pgsql bind pgdb localhost pguser pgpasswd";
|
||||
# ^- DB name ^-Table ^-host ^-user ^-password
|
||||
};
|
||||
|
||||
o Create the database zone table
|
||||
The table must contain the columns "name", "rdtype", and "rdata", and
|
||||
is expected to contain a properly constructed zone. The program "zonetodb"
|
||||
creates such a table.
|
||||
|
||||
zonetodb usage:
|
||||
|
||||
zonetodb origin file dbname dbtable
|
||||
|
||||
where
|
||||
origin : zone origin, eg "pgdb.net."
|
||||
file : master zone database file, eg. pgdb.net.db
|
||||
dbname : name of postgresql database
|
||||
dbtable: name of table in database
|
||||
|
||||
Eg. to import this zone in the file 'pgdb.net.db' into the 'bind' database
|
||||
'pgdb' table:
|
||||
|
||||
---
|
||||
#pgdb.net.db:
|
||||
$TTL 1H
|
||||
@ SOA localhost. root.localhost. ( 1
|
||||
3H
|
||||
1H
|
||||
1W
|
||||
1H )
|
||||
NS localhost.

Issue this command as the pgsql user authorized to update the bind database:
|
||||
|
||||
# zonetodb pgdb.net. pgdb.net.db bind pgdb
|
||||
|
||||
will create / update the pgdb table in the 'bind' db:
|
||||
|
||||
$ psql -dbind -c 'select * from pgdb;'
|
||||
name | ttl | rdtype | rdata

||||
(9 rows)
|
||||
|
||||
I've tested exactly the above configuration with bind-sdb-9.3.1+ and it works OK.
|
||||
|
||||
NOTE: If you use pgsqldb SDB, ensure the postgresql service is started before the named
|
||||
service .
|
||||
|
||||
USE AT YOUR OWN RISK!

Subject: [PATCH] Allow explicit disabling of autodisabled MD5
|
||||
|
||||
Default security policy might include explicitly disabled RSAMD5
|
||||
algorithm. Current FIPS code automatically disables in FIPS mode. But if
|
||||
RSAMD5 is included in security policy, it fails to start, because that
|
||||
algorithm is not recognized. Allow it disabled, but fail on any
|
||||
other usage.

Subject: [PATCH] Disable IDN from environment as documented
|
||||
|
||||
Manual page of host contained instructions to disable IDN processing
|
||||
when it was built with libidn2. When refactoring IDN support however,
|
||||
support for disabling IDN in host and nslookup was lost. Use also
|
||||
environment variable and document it for nslookup, host and dig.
|
||||
|
||||
Support variable CHARSET=ASCII to disable IDN, supported in downstream
|
||||
RH patch since RHEL 5.

Subject: [PATCH] Use proper entropy to initialize tsig keyname
|
||||
|
||||
Random names used on GSS backed nsupdate can conflict in specific
|
||||
situations. That might include starting a lot of machines from
|
||||
containers, where they took all similar time to start. PID and timestamp
|
||||
would be similar and therefore randomness is quite low. Use entropy to
|
||||
generate more random identifier and reduce chance of conflict.

Subject: [PATCH] Have dns_zt_apply lock the zone table
|
||||
|
||||
There where a number of places where the zone table should have
|
||||
been locked, but wasn't, when dns_zt_apply was called.
|
||||
|
||||
Added a isc_rwlocktype_t type parameter to dns_zt_apply and adjusted
|
||||
all calls to using it. Removed locks in callers.
|
||||
|
||||
Modified upstream commit for v9_11

|

Subject: [PATCH] completed and corrected the crypto-random change
|
||||
|
||||
4724. [func] By default, BIND now uses the random number
|
||||
functions provided by the crypto library (i.e.,
|
||||
OpenSSL or a PKCS#11 provider) as a source of
|
||||
randomness rather than /dev/random. This is
|
||||
suitable for virtual machine environments
|
||||
which have limited entropy pools and lack
|
||||
hardware random number generators.
|
||||
|
||||
This can be overridden by specifying another
|
||||
entropy source via the "random-device" option
|
||||
in named.conf, or via the -r command line option;
|
||||
however, for functions requiring full cryptographic
|
||||
strength, such as DNSSEC key generation, this
|
||||
cannot be overridden. In particular, the -r
|
||||
command line option no longer has any effect on
|
||||
dnssec-keygen.
|
||||
|
||||
This can be disabled by building with
|
||||
"configure --disable-crypto-rand".

Subject: [PATCH] Do not keep stale records by default
|
||||
|
||||
By default set max-stale-ttl to 0, unless stale-answer-enable yes. This
|
||||
were enabled by mistake when backporting fix for CVE-2023-2828. It
|
||||
causes increased cache usage on servers not wanting to serve stale
|
||||
records. Fix that by setting smart defaults based on stale answers
|
||||
enabled with possible manual tuning.

Subject: [PATCH] Make alternative named builds testable in system tests
|
||||
|
||||
Red Hat has alternative variant builds of named, which are not ever
|
||||
tested by system tests. New variables make it relatively easy to test
|
||||
alternative variants.
|
||||
|
||||
For sdb variant use:
|
||||
export NAMED_VARIANT=-sdb DNSSEC_VARIANT=
|
||||
|
||||
For pkcs variant use:
|
||||
export NAMED_VARIANT=-pkcs11 DNSSEC_VARIANT=-pkcs11

Subject: [PATCH] Disable random_test
|
||||
|
||||
It fails too often on some architecture, failing the whole build along.
|
||||
Because it runs two times for pkcs11 and normal build and any of
|
||||
subtests can occasionally fail, stop it.
|
||||
|
||||
It can be used again by defining 'unstable' variable in Kyuafile.

Subject: [PATCH] Run .closehandle_cb asynchrounosly in nmhandle_detach_cb()
|
||||
|
||||
When sock->closehandle_cb is set, we need to run nmhandle_detach_cb()
|
||||
asynchronously to ensure correct order of multiple packets processing in
|
||||
the isc__nm_process_sock_buffer(). When not run asynchronously, it
|
||||
would cause:
|
||||
|
||||
a) out-of-order processing of the return codes from processbuffer();
|
||||
|
||||
b) stack growth because the next TCP DNS message read callback will
|
||||
be called from within the current TCP DNS message read callback.
|
||||
|
||||
The sock->closehandle_cb is set to isc__nm_resume_processing() for TCP
|
||||
sockets which calls isc__nm_process_sock_buffer(). If the read callback
|
||||
(called from isc__nm_process_sock_buffer()->processbuffer()) doesn't
|
||||
attach to the nmhandle (f.e. because it wants to drop the processing or
|
||||
we send the response directly via uv_try_write()), the
|
||||
isc__nm_resume_processing() (via .closehandle_cb) would call
|
||||
isc__nm_process_sock_buffer() recursively.
|
||||
|
||||
The below shortened code path shows how the stack can grow:
|
||||
|
||||
1: ns__client_request(handle, ...);
|
||||
2: isc_nm_tcpdns_sequential(handle);
|
||||
3: ns_query_start(client, handle);
|
||||
4: query_lookup(qctx);
|
||||
5: query_send(qctcx->client);
|
||||
6: isc__nmhandle_detach(&client->reqhandle);
|
||||
7: nmhandle_detach_cb(&handle);
|
||||
8: sock->closehandle_cb(sock); // isc__nm_resume_processing
|
||||
9: isc__nm_process_sock_buffer(sock);
|
||||
10: processbuffer(sock); // isc__nm_tcpdns_processbuffer
|
||||
11: isc_nmhandle_attach(req->handle, &handle);
|
||||
12: isc__nm_readcb(sock, req, ISC_R_SUCCESS);
|
||||
13: isc__nm_async_readcb(NULL, ...);
|
||||
14: uvreq->cb.recv(...); // ns__client_request
|
||||
|
||||
Instead, if 'sock->closehandle_cb' is set, we need to run detach the
|
||||
handle asynchroniously in 'isc__nmhandle_detach', so that on line 8 in
|
||||
the code flow above does not start this recursion. This ensures the
|
||||
correct order when processing multiple packets in the function
|
||||
'isc__nm_process_sock_buffer()' and prevents the stack growth.
|
||||
|
||||
When not run asynchronously, the out-of-order processing leaves the
|
||||
first TCP socket open until all requests on the stream have been
|
||||
processed.
|
||||
|
||||
If the pipelining is disabled on the TCP via `keep-response-order`
|
||||
configuration option, named would keep the first socket in lingering
|
||||
CLOSE_WAIT state when the client sends an incomplete packet and then
|
||||
closes the connection from the client side.
|
||||

||||

Subject: [PATCH] Cancel all fetch events in dns_resolver_cancelfetch()
|
||||
|
||||
Although 'dns_fetch_t' fetch can have two associated events, one for
|
||||
each of 'DNS_EVENT_FETCHDONE' and 'DNS_EVENT_TRYSTALE' types, the
|
||||
dns_resolver_cancelfetch() function is designed in a way that it
|
||||
expects only one existing event, which it must cancel, and when it
|
||||
happens so that 'stale-answer-client-timeout' is enabled and there
|
||||
are two events, only one of them is canceled, and it results in an
|
||||
assertion in dns_resolver_destroyfetch(), when it finds a dangling
|
||||
event.
|
||||
|
||||
Change the logic of dns_resolver_cancelfetch() function so that it
|
||||
cancels both the events (if they exist), and in the right order.

When checking if we should enable serve-stale, add an early out case

when the result is an error signalling a duplicate query or a query
|
||||
that would be dropped.

Subject: [PATCH 2/3] Stale answer lookups could loop when over recursion quota
|
||||
|
||||
When a query was aborted because of the recursion quota being exceeded,
|
||||
but triggered a stale answer response and a stale data refresh query,
|
||||
it could cause named to loop back where we are iterating and following
|
||||
a delegation. Having no good answer in cache, we would fall back to
|
||||
using serve-stale again, use the stale data, try to refresh the RRset,
|
||||
and loop back again, without ever terminating until crashing due to
|
||||
stack overflow.
|
||||
|
||||
This happens because in the functions 'query_notfound()' and
|
||||
'query_delegation_recurse()', we check whether we can fall back to
|
||||
serving stale data. We shouldn't do so if we are already refreshing
|
||||
an RRset due to having prioritized stale data in cache.
|
||||
|
||||
In other words, we need to add an extra check to 'query_usestale()' to
|
||||
disallow serving stale data if we are currently refreshing a stale
|
||||
RRset.
|
||||
|
||||
As an additional mitigation to prevent looping, we now use the result
|
||||
code ISC_R_ALREADYRUNNING rather than ISC_R_FAILURE when a recursion
|
||||
loop is encountered, and we check for that condition in
|
||||
'query_usestale()' as well.
|
||||

||||

Subject: [PATCH 3/3] Fix serve-stale hang at shutdown
|
||||
|
||||
The 'refresh_rrset' variable is used to determine if we can detach from
|
||||
the client. This can cause a hang on shutdown. To fix this, move setting
|
||||
of the 'nodetach' variable up to where 'refresh_rrset' is set (in
|
||||
query_lookup(), and thus not in ns_query_done()), and set it to false
|
||||
when actually refreshing the RRset, so that when this lookup is
|
||||
completed, the client will be detached.

||||

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 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.

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 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.

|

|

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 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.

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] Increase even further hazard pointers after KeyTrap
|
||||
|
||||
Extends even more change Downstream specific changes related to KeyTrap,
|
||||
which added safety guards into hazard pointers. Because it seems they
|
||||
are not still enough. Add fixed base to accomodate common threads like
|
||||
main app thread and ldap worker threads. Multiply one more, just to be
|
||||
sure. We do not want to hit maximal limit again.

|
||||
+**Red Hat SELinux BIND Security Profile:**
|
||||
+
|
||||
+By default, Red Hat ships BIND with the most secure SELinux policy
|
||||
+that will not prevent normal BIND operation and will prevent exploitation
|
||||
+of all known BIND security vulnerabilities. See the selinux(8) man page
|
||||
+for information about SElinux.
|
||||
+
|
||||
+It is not necessary to run named in a chroot environment if the Red Hat
|
||||
+SELinux policy for named is enabled. When enabled, this policy is far
|
||||
+more secure than a chroot environment. Users are recommended to enable
|
||||
+SELinux and remove the bind-chroot package.
|
||||
+
|
||||
+*With this extra security comes some restrictions:*
|
||||
+
|
||||
+By default, the SELinux policy does not allow named to write outside directory
|
||||
+/var/named. That directory used to be read-only for named, but write access is
|
||||
+enabled by default now.
|
||||
+
|
||||
+The "named" group must be granted read privelege to
|
||||
+these files in order for named to be enabled to read them.
|
||||
+Any file updated by named must be writeable by named user or named group.
|
||||
+
|
||||
+Any file created in the zone database file directory is automatically assigned
|
||||
+the SELinux file context *named_zone_t* .
|
||||
+
|
||||
+The Red Hat BIND distribution and SELinux policy creates three directories where
|
||||
+named were allowed to create and modify files: */var/named/slaves*, */var/named/dynamic*
|
||||
+*/var/named/data*. The service is able to write and file under */var/named* with appropriate
|
||||
+permissions. They are used for better organisation of zones and backward compatibility.
|
||||
+Files in these directories are automatically assigned the '*named_cache_t*'
|
||||
+file context, which SELinux always allows named to write.
|
||||

Subject: [PATCH] Have dns_zt_apply lock the zone table
|
||||
|
||||
There where a number of places where the zone table should have
|
||||
been locked, but wasn't, when dns_zt_apply was called.
|
||||
|
||||
Added a isc_rwlocktype_t type parameter to dns_zt_apply and adjusted
|
||||
all calls to using it. Removed locks in callers.
|
||||
|
||||
Modified upstream commit for v9_16

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.

.SH SYNOPSIS
|
||||
.B ldap2zone zone-name LDAP-URL default-ttl [serial]
|
||||
.SH DESCRIPTION
|
||||
ldap2zone is a tool that reads info for a zone from LDAP and constructs a standard plain ascii zone file that is written to the standard output. The LDAP information has to be stored using the dnszone schema. The schema is used by BIND with LDAP back-end.
|
||||
|
||||
\fBzone-name\fR
|
||||
.RS 4
|
||||
Name of the zone, eg "mydomain.net."
|
||||
