Hi Geoff,
I actually tried the same approach, I had a small test function that I call
at the start of each thread that initializes, locks, unlocks and destroys
the dyn locks.. and the functions are properly called.
unsigned long lock, lock2 = 0;
printf("About to test\n");
lock = CRYPTO_get_new_dynlockid();
lock2 = CRYPTO_get_new_dynlockid();
printf("Got new locks %lu, %lu\n", lock, lock2);
CRYPTO_w_lock(lock);
printf("Locked the lock\n");
CRYPTO_w_unlock(lock);
printf("Unlocked the lock\n");
CRYPTO_destroy_dynlockid(lock);
CRYPTO_destroy_dynlockid(lock2);
printf("Destroyed the locks, DONE\n");
the result, for each new thread is:
Got new locks 4294967283, 4294967295
Locked the lock
Unlocked the lock
Destroyed the locks, DONE
and in the logs, the functions properly log the start and end of each _dyn_
function, that is:
...
Nov 21 17:36:19 ncipher168 ocspd[26357]: _dyn_create_callback() start
Nov 21 17:36:19 ncipher168 ocspd[26357]: _dyn_create_callback() stop
Nov 21 17:36:19 ncipher168 ocspd[26357]: _dyn_lock_callback() start
Nov 21 17:36:19 ncipher168 ocspd[26357]: _dyn_lock_callback() end
...
Therefore it seems that the callbacks are properly registered!
The problem is that they are not called by the nCipher driver - no sign
at all in the logs... :( How come they are not called ???
Later,
Max

Hi David,
that is really nice.. although.. after I gave it a try... it does not
really work :(
Actually, it seems that the dynamic functions are never called... :(
Investigating...
The attached example seems to work. I put it in the top-level directory
of the (built) openssl tree and compiled with;
gcc -Wall -Iinclude -o foobar foobar.c -L. -lcrypto
The output shows that dynamic lockids are negative;
About to test
Created lock 'dyn_lck.c:257'
Created lock 'dyn_lck.c:257'
Got new locks -1, -2
Doing mode 9 lock on 'dyn_lck.c:257' from foobar.c:47
Locked the lock
Doing mode 10 lock on 'dyn_lck.c:257' from foobar.c:49
Unlocked the lock
Destroying lock 'dyn_lck.c:257' from dyn_lck.c:329
Destroying lock 'dyn_lck.c:257' from dyn_lck.c:329
Destroyed the locks, DONE
Perhaps that'll help distinguish what's going on in your code?
Cheers,
Geoff
