#52725: OpenSSH does not use PKCS11Provider, and calls for wrong key type -------------------------+-------------------------------- Reporter: mouse07410 | Owner: macports-tickets@… Type: defect | Status: new Priority: Normal | Milestone: Component: ports | Version: 2.3.4 Resolution: | Keywords: Port: openssl | -------------------------+-------------------------------- Comment (by mouse07410): The first issue was my fault - I wish I could edit the title to remove the "PKCS11Provider" part. I am using OpenSSH (the current Macports version) with an RSA smart card. PKCS11 support is provided by OpenSC (the current GitHub master, well- tested and working fine). The problem is - despite the token being RSA, it tries to ask for ECDSA keys, which of course results in 4 error messages. Since the connection succeeds, one can consider it a nuisance rather than a show-stopper, but it would be far nicer if you could help to get rid of those requests that cause those errors. Here's what it looks like: {{{ $ ssh github.com C_GetAttributeValue failed: 18 C_GetAttributeValue failed: 18 C_GetAttributeValue failed: 18 C_GetAttributeValue failed: 18 Enter PIN for 'PIV Card Holder pin (PIV_II)': PTY allocation request failed on channel 0 Hi mouse07410! You've successfully authenticated, but GitHub does not provide shell access. Connection to github.com closed. $ }}} The connection/authentication succeeds - but before that ssh is trying to request ECC parameters from an RSA token, which causes the above errors. Here's the PKCS11SPY trace: {{{ Log This seems relevant. Note that the token is RSA and has nothing ECC- related in/on it. $ ssh -I /Library/OpenSC/lib/pkcs11-spy. github.com pkcs11-spy.dylib pkcs11-spy.la pkcs11-spy.so $ ssh -I /Library/OpenSC/lib/pkcs11-spy.dylib github.com *************** OpenSC PKCS#11 spy ***************** Loaded: "/Library/OpenSC/lib/opensc-pkcs11.dylib" 0: C_GetFunctionList 2016-10-24 21:49:02.207 Returned: 0 CKR_OK 1: C_Initialize 2016-10-24 21:49:02.207 [in] pInitArgs = 0x0 Returned: 0 CKR_OK 2: C_GetInfo 2016-10-24 21:49:02.947 [out] pInfo: cryptokiVersion: 2.20 manufacturerID: 'OpenSC Project ' flags: 0 libraryDescription: 'OpenSC smartcard framework ' libraryVersion: 0.16 Returned: 0 CKR_OK 3: C_GetSlotList 2016-10-24 21:49:02.947 [in] tokenPresent = 0x1 [out] pSlotList: Count is 1 [out] *pulCount = 0x1 Returned: 0 CKR_OK 4: C_GetSlotList 2016-10-24 21:49:02.949 [in] tokenPresent = 0x1 [out] pSlotList: Slot 0 [out] *pulCount = 0x1 Returned: 0 CKR_OK 5: C_GetTokenInfo 2016-10-24 21:49:02.950 [in] slotID = 0x0 [out] pInfo: label: 'PIV Card Holder pin (PIV_II) ' manufacturerID: 'piv_II ' model: 'PKCS#15 emulated' serialNumber: 'a0fxxxxxxxxxxxxx' ulMaxSessionCount: 0 ulSessionCount: 0 ulMaxRwSessionCount: 0 ulRwSessionCount: 0 ulMaxPinLen: 8 ulMinPinLen: 4 ulTotalPublicMemory: -1 ulFreePublicMemory: -1 ulTotalPrivateMemory: -1 ulFreePrivateMemory: -1 hardwareVersion: 0.0 firmwareVersion: 0.0 time: ' ' flags: 40d CKF_RNG CKF_LOGIN_REQUIRED CKF_USER_PIN_INITIALIZED CKF_TOKEN_INITIALIZED Returned: 0 CKR_OK 6: C_OpenSession 2016-10-24 21:49:02.968 [in] slotID = 0x0 [in] flags = 0x6 pApplication=0x0 Notify=0x0 [out] *phSession = 0x7fee5fd09720 Returned: 0 CKR_OK 7: C_FindObjectsInit 2016-10-24 21:49:02.968 [in] hSession = 0x7fee5fd09720 [in] pTemplate[1]: CKA_CLASS CKO_PUBLIC_KEY Returned: 0 CKR_OK 8: C_FindObjects 2016-10-24 21:49:02.968 [in] hSession = 0x7fee5fd09720 [in] ulMaxObjectCount = 0x1 [out] ulObjectCount = 0x1 Object 0x7fee5ff04490 matches Returned: 0 CKR_OK 9: C_GetAttributeValue 2016-10-24 21:49:02.968 [in] hSession = 0x7fee5fd09720 [in] hObject = 0x7fee5ff04490 [in] pTemplate[3]: CKA_ID 0000000000000000 / 0 CKA_MODULUS 0000000000000000 / 0 CKA_PUBLIC_EXPONENT 0000000000000000 / 0 [out] pTemplate[3]: CKA_ID 0000000000000000 / 1 CKA_MODULUS 0000000000000000 / 256 CKA_PUBLIC_EXPONENT 0000000000000000 / xxx Returned: 0 CKR_OK 10: C_GetAttributeValue 2016-10-24 21:49:02.968 [in] hSession = 0x7fee5fd09720 [in] hObject = 0x7fee5ff04490 [in] pTemplate[3]: CKA_ID 00007fee5fc25b20 / 1 CKA_MODULUS 00007fee5fc26e30 / 256 CKA_PUBLIC_EXPONENT 00007fee5fc25240 / xxx [out] pTemplate[3]: CKA_ID 00007fee5fc25b20 / 1 00000000 01 .

Since so far ssh only supports RSA tokens, I might understand not asking for the key type - but then it's rather strange to see it asking for ECDSA_PARAMS. And since in general (not on PKCS#11 tokens) ssh does support ECC keys - I could understand asking for ECDSA_PARAMS, but then - only after checking the key type, which ssh did not. So something is broken. Possibly upstream. -- Ticket URL: <https://trac.macports.org/ticket/52725#comment:3> MacPorts <https://www.macports.org/> Ports system for OS X
