Stack smashing detected
Perhaps the problem occurs with a large table size. | Field | Type | Null | Key | Default | Extra | The table I'm trying to index has two fields and 118272519 rows: I found the following post describing a similar-sounding problem, but wasn't able to find any bug reports on the issue: However, the mysql session crashed (log of backtrace\memory map attached in next reply) with "*** stack smashing detected ***: mysql terminated".
#Stack smashing detected code
I’m using using gcc version ((Ubuntu 8.2.0-7ubuntu1) 8.2.0) my main file contains the following code //Header Files include#Stack smashing detected how to
The repair took 2 days 4 hours, and looks like it succeeded (I don't know how to verify). Hie there, when executing the following code, I get stack smashing detected : terminated Aborted (core dumped). Repair NO_WRITE_TO_BINLOG table table_tmp QUICK Then I moved the MYD file to correspond to the new table, and then ran: I created an empty table with identical layout except that it already has an index defined on the field I would like indexed. This is a security mechanism implemented by gcc/g++ to prevent buffer overflow exploits using -fstack-protector. So instead, I used a method described here: stack smashing detected error occurs when as the name suggests, you smash the stack, meaning that you have a buffer overflow and the canarygets overwritten by a different value. I ran into performance issues when attempting to build an index on a single field of a large table (1.5 TB).
Instead, the JVM is crashed without so much as a crash log. So the native method finished its execution just fine, but the control was not returned to Java. This program should make clear about the error message, in the case of canary value change.I'm running a MySQL server with a data_dir pointing to an NFS mount exported from a NAS device. java -jar build/libs/checksum.jar 123456789012.txt Exiting native method with checksum: 1804289383 stack smashing detected : java terminated. * The loop is added only to keep gcc happy. _attribute_ ((noreturn)) internal_function In the same GNU library i also found fortify_fail.c #include So this code simply calls _fortify_fail with argument “smash the stack”. check would only be detected after the function nishes, giving the attacker a code window to play with, as we’ll discuss in Section 3.1. Programs that have been compiled with StackGuard are largely. If you can't find the problem by reading your code, run your program under a debugger like gdb and try to reproduce the overrun. Stack smashing attacks are the most common form of pene-tration attack. Please suggest/point me in the right direction. GnanaShekar Subramani Janu0 Comments Hi, We have recently migrated to AIX 7.1. Also, in C/C++, NULL is often defined as 0. AIX 7.1: Traceroute Stack Smashing Detected Program Terminated. As someone else suggested, look carefully at your code where you access array indices or do pointer arithmetic. I found this source code form GNU C Library at debug/stack_chk_fail.c Even you can find it from this link buffer overrun) is a HUGE security issue. _fortify_fail ("stack smashing detected") #includeĮxtern char **_libc_argv attribute_hidden Lets see what does that function contain.
if not library routine is beginning called through the PLT. Than after the “print” operation there is check of canary value that can be seen in line 11, 12 in the case of same value it is moved to 15th line and then return the program normally. When you look at line 5 you could see that some value from global section is moved to $eax and in the next line it is pushed on to the stack. gcc -m32 -fstack-protector-all hello.c -o hello On many C implementations it is possible to corrupt the execution stack by writing past the end of an array declared auto in a routine. Later i started working on it with a small HelloWorld program which has canary enabled. Smashing The Stack For Fun And Profit by Aleph One smash the stack C programming n. Recently i was thinking about on how does the canary work in Linux Glibc.
