From 0fc3c803c34311eb05c5c7a7e710c8591b592649 Mon Sep 17 00:00:00 2001

Subject: [PATCH] Ticket 49313 - Change the retrochangelog default cache size
Bug Description:
Default retroCL backend entry cache size is 2Mb.
It has been reported in many deployments that DB corruption could
be prevented by increasing entry cache to 200Mb.
There is no identified reproducible steps to debug this DB corruption.
So to prevent this problem we are increasing the entry cache
Fix Description:
Set default cn=changelog cache to 200Mb (based on production cases)
An other option would be to set a maximum number of entries but
as we do not know if it works to prevent DB corruption, let's prefere
entry cache size

Subject: [PATCH] Ticket 49287 - v3 extend csnpl handling to multiple backends
The csn pending list mechanism failed if internal operation affected multiple backends
This fix is an extension to the fix in ticket 49008, the thread local data now also contains
a list of all affected replicas.

From 95b39e29361812a62f2e038c89a88d717c82794e Mon Sep 17 00:00:00 2001
From: William Brown <firstyear@redhat.com>

Subject: [PATCH] Ticket 49336 - SECURITY: Locked account provides different
return code
Bug Description: The directory server password lockout policy prevents binds
from operating once a threshold of failed passwords has been met. During
this lockout, if you bind with a successful password, a different error code
is returned. This means that an attacker has no ratelimit or penalty during
an account lock, and can continue to attempt passwords via bruteforce, using
the change in return code to ascertain a sucessful password auth.
Fix Description: Move the account lock check *before* the password bind
check. If the account is locked, we do not mind disclosing this as the
attacker will either ignore it (and will not bind anyway), or they will
be forced to back off as the attack is not working preventing the
bruteforce.

Subject: [PATCH] Ticket 49298 - force sync() on shutdown
Bug Description: During shutdown on xfs we would occasionally
see a broke dse.ldif (specifically, empty). This happens due to
a bug in xfs where the directory isn't synced on rename().
Fix Description: As we shutdown call sync() to force all our
writes to disk - dse.ldif, logs, db, all of it.

Subject: [PATCH] Ticket 49356 - mapping tree crash can occur during tot init
Bug Description: Two faults were found in the handling of the mapping
tree of 389 directory server. The first fault was that the tree-free
check was not performed atomically and may cause an incorrect operations
error to be returned. The second was that during a total init the referral
would not lock the be, but the pw_verify code assumed a be was locked.
This caused a segfault.
Fix Description: Fix the freed check to use atomics. Fix the pw_verify
to assert be is NULL (which is correct, there is no backend).
