I normally use EAP-PEAP but i couldnt get the server to segfault in valgrind with that. Think it was openssl that grinded it to a halt. Tried with EAP-MD5 instead and it produced the desired result. I'm running FC4 on one of my machines, and I don't see the same problem with the CVS head of 1.1 (i.e. 1.1.1 + a few patches that shouldn't affect this). And looking at what valgrind *is* complaining about, I can't see for the life of me why the code depends on uninitialized values. If I walk back up the callstack valgrind shows, the code clearly initializes the data structures. In general, a lot of 'unitialized value' errors that valgrind complains about come from the network libs. If you ignore the 'unitialized value' errors in the valgrind log then you come to the real errors, 'Invalid Write', 'Invalid Read' to/from memory areas that aren't part of the server or were previously freed. The first real error I can see in the log is ==15822== Thread 24: ==15822== Invalid write of size 4 ==15822==at 0x457D797: eaplist_find (mem.c:332) ==15822==by 0x457C2F7: eap_handler (eap.c:993) ==15822==by 0x457BC11: eap_authenticate (rlm_eap.c:230) ==15822==by 0x8054775: modcall (modcall.c:236) ==15822==by 0x8054CF8: call_one (modcall.c:269) ==15822==by 0x80549B9: modcall (modcall.c:324) ==15822==by 0x8052D6F: indexed_modcall (modules.c:469) ==15822==by 0x804CC27: rad_check_password (auth.c:367) ==15822==by 0x804D16B: rad_authenticate (auth.c:662) ==15822==by 0x8055D05: rad_respond (radiusd.c:1642) ==15822==by 0x805C5B6: request_handler_thread (threads.c:517) ==15822==by 0x4053CB6: start_thread (in /lib/tls/libpthread.so.0) ==15822== Address 0x5A17BEC is 4 bytes inside a block of size 72 free'd ==15822==at 0x401C178: free (vg_replace_malloc.c:235) ==15822==by 0x457D564: eap_handler_free (mem.c:142) ==15822==by 0x457BF3E: eap_authenticate (rlm_eap.c:268) ==15822==by 0x8054775: modcall (modcall.c:236) ==15822==by 0x8054CF8: call_one (modcall.c:269) ==15822==by 0x80549B9: modcall (modcall.c:324) ==15822==by 0x8052D6F: indexed_modcall (modules.c:469) ==15822==by 0x804CC27: rad_check_password (auth.c:367) ==15822==by 0x804D16B: rad_authenticate (auth.c:662) ==15822==by 0x8055D05: rad_respond (radiusd.c:1642) ==15822==by 0x805C5B6: request_handler_thread (threads.c:517) ==15822==by 0x4053CB6: start_thread (in /lib/tls/libpthread.so.0) which is a write to some memory that we previously held, but have since free'd.
