190327 9:40:07 [ERROR] mysqld got signal 6 ;
|
This could be because you hit a bug. It is also possible that this binary
|
or one of the libraries it was linked against is corrupt, improperly built,
|
or misconfigured. This error can also be caused by malfunctioning hardware.
|
|
|
To report this bug, see https://mariadb.com/kb/en/reporting-bugs
|
|
|
We will try our best to scrape up some info that will hopefully help
|
diagnose the problem, but since we have already crashed,
|
something is definitely wrong and this may fail.
|
|
|
Server version: 10.2.24-MariaDB-debug-log
|
key_buffer_size=1048576
|
read_buffer_size=131072
|
max_used_connections=1
|
max_threads=153
|
thread_count=8
|
It is possible that mysqld could use up to
|
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 63102 K bytes of memory
|
Hope that's ok; if not, decrease some variables in the equation.
|
|
|
Thread pointer: 0x62a00008a270
|
Attempting backtrace. You can use the following information to find out
|
where mysqld died. If you see no messages after this, something went
|
terribly wrong...

200116 6:58:53 [ERROR] mysqld got signal 6 ;
|
This could be because you hit a bug. It is also possible that this binary
|
or one of the libraries it was linked against is corrupt, improperly built,
|
or misconfigured. This error can also be caused by malfunctioning hardware.
|
|
|
To report this bug, see https://mariadb.com/kb/en/reporting-bugs
|
|
|
We will try our best to scrape up some info that will hopefully help
|
diagnose the problem, but since we have already crashed,
|
something is definitely wrong and this may fail.
|
|
|
Server version: 10.2.31-MariaDB-debug-log
|
key_buffer_size=1048576
|
read_buffer_size=131072
|
max_used_connections=1
|
max_threads=153
|
thread_count=8
|
It is possible that mysqld could use up to
|
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 63103 K bytes of memory
|
Hope that's ok; if not, decrease some variables in the equation.
|
|
|
Thread pointer: 0x62a00008a208
|
Attempting backtrace. You can use the following information to find out
|
where mysqld died. If you see no messages after this, something went
|
terribly wrong...

SUMMARY: AddressSanitizer: heap-use-after-free /git/10.4/strings/strend.c:45 in strend
|
Issue is related to charset_dir var. There are two charset_dir variables one on client side and the other on server side.
Client variable: mysql->options.charset_dir
Server variable: 'charsets_dir'
On 'mysql_close_free_options' the client side variable gets freed and initialized with zero. On some cases the server variable points to the client variable and when the server variable tries to access the freed memory, ASAN issue gets reported. Need to identify the exact race scenario and fix the issue.
The issue happens due to the race between 'save' and 'restore' of 'charsets_dir' global variable
In multi-source replication the slave server tries to establish two `mysql` connections with two master servers.

They both reach 'mysql_set_character_set_with_default_collation'. Within this function two variables are of our
interest.
1. charsets_dir : It is a global variable. It points to static array i.e static char mysql_charsets_dir[FN_REFLEN+1]
2. mysql->options.charset_dir : It is dynamically allocated on heap.
File Name: sql/slave.cc
Function Name: `connect_to_master` provides 'charsets_dir' as argument to `mysql_options` to create 'mysql->options.charset_dir'. Then memory is dynamically allocated and it holds copy of 'charsets_dir'.
/* This one is not strictly needed but we have it here for completeness */
mysql_options(mysql, MYSQL_SET_CHARSET_DIR, (char *) charsets_dir);
File Name: sql-common/client.c
case MYSQL_SET_CHARSET_DIR:
my_free(mysql->options.charset_dir);
mysql->options.charset_dir= opt_strdup(arg,MYF(MY_WME)); (Memory gets allocated on heap)
3. Within 'mysql_set_character_set_with_default_collation '
static void mysql_set_character_set_with_default_collation(MYSQL *mysql)
|
{
|
const char *save= charsets_dir;
|
if (mysql->options.charset_dir)
|
charsets_dir=mysql->options.charset_dir;
|
...
|
charsets_dir= save;
|
}
|
|
For example:
charsets_dir=mysql_charsets_dir=0x56164f9747e0
mysql->options.charset_dir:0x607000080098 (mysql_1)
mysql->options.charset_dir:0x607000087098 (mysql_2)

multi_source.mdev-9544 'innodb' w5 [ pass ] 2551
|
|
|
MTR's internal check of the test case 'multi_source.mdev-9544' failed.
|
This means that the test case does not preserve the state that existed
|
before the test case was executed. Most likely the test case did not
|
do a proper clean-up. It could also be caused by the previous test run
|
by this thread, if the server wasn't restarted.
|
This is the diff of the states of the servers before and after the
|
test case was executed:

Yes, I think that the MemorySanitizer in recent clang can catch heap-use-after-free, by declaring freed memory as uninitialized. There is also MSAN_OPTIONS=poison_in_dtor=1 which was recently enabled by default; see MDEV-30942.
Here is one more recent failure:

The reason why I got interested in this test was that I got this local test failure yesterday for a 10.6 based branch:
multi_source.mdev-9544 'innodb' w30 [ pass ] 2264
|
|
|
MTR's internal check of the test case 'multi_source.mdev-9544' failed.
|
…
|
-CHARACTER_SETS_DIR /mariadb/10.6/sql/share/charsets/
|
+CHARACTER_SETS_DIR ????????????????????????????????????????
|
This would not be flagged as a failure by mtr, so I would guess it to be rather common on buildbot as well.
I encountered this yesterday again:

This is a real serious issue in the server code that needs to be fixed, and there's already a perfect analysis by Sujatha from 3 years ago.
I was able to reproduce easily with valgrind by injecting a small sleep and repeat-running the test:

I have a fix for this in st-10.5-knielsen, but I'm blocked from pushing by broken branch protection on github. Feel free to pull the branch if desired.
