Hi All,<br>
<br>
I am using OpenSSL 1.0.1l<span style="color: rgb(0, 0, 0);
font-family: 'Times New Roman'; font-size: medium; font-style:
normal; font-variant: normal; font-weight: normal; letter-spacing:
normal; line-height: normal; orphans: auto; text-align: start;
text-indent: 0px; text-transform: none; white-space: normal;
widows: auto; word-spacing: 0px; -webkit-text-stroke-width: 0px;
display: inline !important; float: none; background-color:
rgb(240, 240, 240);"><span class="Apple-converted-space"></span></span>
in Win32 environment. At the beginning of my program I call<br>
<br>
SSL_library_init();<br>
SSL_load_error_strings();<br>
<br>
Those functions are only called once.<br>
<br>
Then I have 3 threads which can't possibly be run at the same time
due to mutexes I'm setting with WaitForSingleObject and
ReleaseMutex. Those 3 threads use these functions below and all
variables in those threads are local to the threads (e.g. no
globals).<br>
<br>
SSL_CTX_new<br>
SSL_CTX_set_verify<br>
SSL_CTX_set_cert_verify_callback<br>
BIO_new_connect<br>
BIO_do_connect<br>
SSL_new<br>
SSL_set_bio<br>
SSL_get_peer_certificate<br>
SSL_write<br>
SSL_read<br>
SSL_get_error<br>
<br>
<br>
(cleanup functions.. if conditions used to prevent double frees,
etc.)<br>
X509_free<br>
SSL_shutdown<br>
SSL_free<br>
BIO_free<br>
SSL_CTX_free<br>
<br>
<br>
<br>
<br>
My questions are the following:<br>
<br>
1) Am I correct that I only need to call the SSL_library_init();
and SSL_load_error_strings(); once at the beginning of the program
, and not at the beginning of each thread?<br>
2) Should I be doing any other cleanup functions within the
threads?<br>
<br>
My program appears to work perfectly but a tool is complaining about
memory leaks in _CRYPTO_malloc, _asn1_enc_save, _asn1_item_ex_d2i,
_d2i_X509<br>
<br>
Handle leaks<br>
<br>
_shmem_winpthreads_grab<br>
_pthread_register_pointer<br>
<br>
In fact I get memory leaks reported if I just do
SSL_library_init(); alone<br>
<br>
Despite the reports of the leaks my program seems to run fine for
days and stay consistent in memory used. But I'm feeling paranoid
something just isn't quite right.<br>
<br>
Should I be doing any other cleanup operations?<br>
<br>
Thanks for the assistance.<br>
<br>
Best Regards,<br>
<br>
