I hope you won't be drowned by this flaw of information but I also hope I gave you enough information so you could be able to give me a hand. Regards, Grégory BELLIER.

Help needed
Hello, I am implementing an engine for our company's hardware. I completed the engine body part by referencing other engine implementation. But I have a problem about the shared library which will be loaded by DSO_load function and bond to with some functions. I assume that the shared library should contain: 1: The engine itself built for the dynamic load; 2: The lower level interface functions which interface with the device drivers; When I built the shared library, there is no problem to use the following command: openssl engine - dynamic -pre SO_PATH:/x/librenesas.so -pre LOAD But if I run an aes-128-cbc encryption command by using the engine, the following error message comes out. OpenSSL aes-128-cbc -in ifile -out ofile -e -K 12345678901234567890123456789012 -iv 00 -engine renesas openssl (lock_dbg_cb): already locked (mode=9, type=30) at e_renesas.c:276 openssl (lock_dbg_cb): not locked (mode=10, type=30) at eng_table.c:173 can't use that engine 1174:error:25066067:DSO support routines:DLFCN_LOAD:could not load the shared library:dso_dlfcn.c:162:filename(librenesas.sy 1174:error:25070067:DSO support routines:DSO_load:could not load the shared library:dso_lib.c:244: 1174:error:80067069:RainerAPI:RENESAS_ENGINE_INIT:reason(105):e_renesas.c:249: 1174:error:260B806D:engine routines:ENGINE_TABLE_REGISTER:init failed:eng_table.c:161: It looks that I have two problems: 1: DSO_bind_func couldn't be successful; 2: The engine is locked already when I tried to use CRYPOT_w_lock function Does anyone have any suggestion and advice? Thanks a lot in advance, Weidong
