event_class_mask)'
check_audit_mask(mysql_global_audit_mask, event_class_mask) is tested in
mysql_audit_general_log() and then assert in mysql_audit_acquire_plugins()
verifies that the condition still holds.
But this code path is not protected by LOCK_audit_mask, so
mysql_global_audit_mask can change its value between the if() and the
assert. That is, the assert is invalid and will fire if the
audit plugin is unloaded concurrently with mysql_audit_general_log().
Nothing bad will happen in this case though, we'll just do a useless
loop over all remaining installed audit plugins.
That is, the fix is simply to remove the assert.

The issue manifests due to a bug in mysql_routine_grant. This was a side
effect of e46eea8660fb which fixed the problem of not giving appropriate error
message (ER_NONEXISTING_PROC_GRANT) when a routine grant existed due to role
inheritance.
When granting a routine privilege, it is possible to have a GRANT_NAME
entry already created from an inherited role, but with it's init_privs
set to 0.
In this case we must not create a *new* grant entry, but we must edit
this grant entry to set its init_privs.
Note that this case was already covered by MDEV-29458, however due to a
forgotten "flush privileges;" the actual code path never got hit.
Remove the flush privilege command as it was never intended to be there
in the first place.

There was an issue in updating in-memory role datastructures when
propagating role grants.
The issue is that changing a particular role's privilege (on any
privilege level, global, database, etc.)
was done such that it overwrote the entire set of bits for that
particular level of privileges.
For example:
grant select on *.* to r1 -> sets the access bits to r1 to select,
regardless of what bits were present for role r1 (inherited from any
other roles).
Before this fix, the rights of role r1 were propagated to any roles r1
was granted to, however the propagated rights did *not* include the
complete rights r1 inherited from its own grants.
For example:
grant r2 to r1;
grant select on *.* to r2;
grant insert on *.* to r1; # This command completely disregards the
# select privilege from r2.
In order to correct this, ensure that before rights are propagated
onwards, that the current's role rights have been updated from its
grants.
Additionally, the patch exposed a flaw in the DROP ROLE code.
When deleting a role we removed all its previous grants, but what
remained was the actual links of roles granted to the dropped role.
Having these links present when propagating grants meant that we would
have leftover ACL_xxx entries.
Ensure that the links are removed before propagating grants.

column
There was a bug in the ACL internal data structures GRANT_TABLE and
GRANT_COLUMN. The semantics are: GRANT_TABLE::init_cols and
GRANT_COLUMN::init_privs represent the bits that correspond to the
privilege bits stored in the physical tables. The other struct members
GRANT_TABLE::cols and GRANT_COLUMN::privs represent the actual access
bits, as they may be modified through role grants.
The error in logic was mixing the two fields and thus we ended up
storing the logical access bits in the physical tables, instead of the
physical (init_xxx) bits.
This caused subsequent DBUG_ASSERT failures when dropping the involved
roles.

replication on the slave in the presence of replication filters
Problem:
========
Replication can break while applying a query log event if its
respective command errors on the primary, but is ignored by the
replication filter within Grant_tables on the replica. The bug
reported by MDEV-28530 shows this with REVOKE ALL PRIVILEGES using a
non-existent user. The primary will binlog the REVOKE command with
an error code, and the replica will think the command executed with
success because the replication filter will ignore the command while
accessing the Grant_tables classes. When the replica performs an
error check, it sees the difference between the error codes, and
replication breaks.
Solution:
========
If the replication filter check done by Grant_tables logic ignores
the tables, reset thd->slave_expected_error to 0 so that
Query_log_event::do_apply_event() can be made aware that the
underlying query was ignored when it compares errors.
Note that this bug also effects DROP USER if not all users exist
in the provided list, and the patch fixes and tests this case.

Spider converts HA_READ_KEY_EXACT to the equality (=) in the
function spider_db_append_key_where_internal() but the conversion
is not necessarily correct for tables with prefix indices.
We fix the bug by converting HA_READ_KEY_EXACT to 'LIKE "foo%"' when
a target key is a prefix key. The fix is partly inspired by FEDERATED.
See ha_federated::create_where_from_key() for more details.

Thanks to references from Brad Smith, BSDs use getmntinfo as
a system call for mounted filesystems.
Most BSDs return statfs structures, (and we use OSX's statfs64),
but NetBSD uses a statvfs structure.
Simplify Linux getmntent_r to just use getmntent.
AIX uses getmntent.
An attempt at writing Solaris compatibility with
a small bit of HPUX compatibility was made based on man page
entries only. Fixes welcome.
statvfs structures now use f_bsize for consistency with statfs
Test case adjusted as PATH_MAX is OS defined (e.g. 1023 on AIX)
Fixes: 0ee5cf837e3a0464acc20db2a2aee0adaff3f2ac
also fixes:
MDEV-27818: Disk plugin does not show zpool mounted devices
This is because zpool mounted point don't begin with /.
Due to the proliferation of multiple filesystem types since this
was written, we restrict the entries listed in the disks plugin
to excude:
* read only mount points (no point monitoring, and
includes squash, snaps, sysfs, procfs, cgroups...)
* mount points that aren't directories (excludes /etc/hostname and
similar mounts in containers). (getmntent (Linux/AIX) only)
* exclude systems where there is no capacity listed (excludes various
virtual filesystem types).

The fkid[] must accommodate both the database name (which is already

(which must be converted to my_charset_filename) so that we can check
if it is in the format databasename/tablename_ibfk_1 (all encoded in

This bug affected some queries with an IN/ALL/ANY predicand or an EXISTS
predicate whose subquery contained a GROUP BY clause that could be
eliminated. If this clause used a IN/ALL/ANY predicand whose left operand
was a single-value subquery then execution of the query caused a crash of
the server after invokation of remove_redundant_subquery_clauses().
The crash was caused by an attempt to exclude the unit for the single-value
subquery from the query tree for the second time by the function
Item_subselect::eliminate_subselect_processor().
This bug had been masked by the bug MDEV-28617 until a fix for the latter
that properly excluded units was pushed into 10.3.

it is safe to invoke btr_search_drop_page_hash_index(block, true)

Any attempt to upgrade page latches is prone to deadlocks. Recently,
we observed a few hangs that involved nothing more than a small table
consisting of one clustered index page, one secondary index page and
some undo pages.

Problem:
========
When replicating SET DEFAULT ROLE, the pre-update check (i.e. that
in set_var_default_role::check()) tries to validate the existence of
the given rules/user even when the targeted tables are ignored. When
previously issued CREATE USER/ROLE commands are ignored by the
replica because of the replication filtering rules, this results in
an error because the targeted data does not exist.
Solution:
========
Before checking that the given roles/user exist of a SET DEFAULT
ROLE command, first ensure that the mysql.user and
mysql.roles_mapping tables are not excluded by replication filters.

Reason:
=======
Race condition between btr_search_drop_hash_index() and
btr_search_lazy_free(). One thread does resizing of buffer pool
and clears the ahi on all pages in the buffer pool, frees the
index and table while removing the last reference. At the same time,
other thread access index->heap in btr_search_drop_hash_index().
Solution:
=========
Acquire the respective ahi latch before checking index->freed()
btr_search_drop_page_hash_index(): Added new parameter to indicate
that drop ahi entries only if the index is marked as freed
btr_search_check_marked_free_index(): Acquire all ahi latches and

Even though commit b817afaa1c148437e1016d1981f138d0c46ccbc8 passed
the test mariabackup.compress_qpress, that test turned out to be
too small to reveal one more problem that had previously been prevented
by the existence of ctrl_mutex. I did not realize that there can be
multiple concurrent callers to compress_write(). One of them is the
log copying thread; further callers are data file copying threads
(default: --parallel=1).
By default, there is only one compression worker thread
(--compress-threads=1).
compress_write(): Fix a race condition between threads that would
use the same worker thread object. Make thd->data_avail contain the
thread identifier of the submitter, and add thd->avail_cond to
notify other compress_write() threads that are waiting for a slot.
