2020-01-30 | s390/pkey/zcrypt: Support EP11 AES secure keys | Harald Freudenberger | |
Extend the low level ep11 misc functions implementation by several functions to support EP11 key objects for paes and pkey: - EP11 AES secure key generation - EP11 AES secure key generation from given clear key value - EP11 AES secure key blob check - findcard function returns list of apqns based on given criterias - EP11 AES secure key derive to CPACF protected key Extend the pkey module to be able to generate and handle EP11 secure keys and also use them as base for deriving protected keys for CPACF usage. These ioctls are extended to support EP11 keys: PKEY_GENSECK2, PKEY_CLR2SECK2, PKEY_VERIFYKEY2, PKEY_APQNS4K, PKEY_APQNS4KT, PKEY_KBLOB2PROTK2. Additionally the 'clear key' token to protected key now uses an EP11 card if the other ways (via PCKMO, via CCA) fail. The PAES cipher implementation needed a new upper limit for the max key size, but is now also working with EP11 keys.

2020-01-30 | s390/zcrypt: extend EP11 card and queue sysfs attributes | Harald Freudenberger | |
This patch introduces new sysfs attributes for EP11 cards and queues: An EP11 card gets four new sysfs attributes: /sys/devices/ap/cardxx/API_ordinalnr The EP11 card firmware API ordinal number. /sys/devices/ap/cardxx/FW_version The EP11 card firmware major and minor version. /sys/devices/ap/cardxx/serialnr Displays the serial number of the EP11 card. The serial number is a 16 character string unique for this EP11 card. /sys/devices/ap/cardxx/op_modes Displays operation modes for this EP11 card. Known operation modes are: FIPS2009, BSI2009, FIPS2011, BSI2011 and BSICC2017. The EP11 queues get two new sysfs attributes: /sys/devices/ap/cardxx/xx.yyyy/mkvps Displays information about the master key(s) states and verification patterns. Two lines are displayed: WK CUR: <wk_cur_state> <wk_cur_vp> WK NEW: <wk_new_state> <wk_new_vp> with <wk_cur_state>: 'invalid' or 'valid' <wk_new_state>: 'empty' or 'uncommitted' or 'committed' <wk_cur_vp> and <wk_new_vp>: '-' or a 32 byte hash pattern /sys/devices/ap/cardxx/xx.yyyy/op_modes Displays operation modes for this EP11 queue. Known operation modes are: FIPS2009, BSI2009, FIPS2011, BSI2011 and BSICC2017. The card information displayed with the sysfs attributes is fresh fetched from the card if the card is online, otherwise cached values are used. The queue information displayed with the sysfs attributes is always fetched on the fly and not cached. So each read of any of these sysfs attributes will cause an request/reply CPRB communication with the EP11 crypto card. The queue attributes address the corresponding EP11 domain within the EP11 card. The card attributes addresses any domain within the EP11 card (subject to the dispatch algorithm within the zcrypt device driver). If the addressed domain is offline or for card addressing all domains are offline the attributes will display '-' for state and verification patterns and an empty string for op mode, serial number, API_ordinalnr and FW_version.

2020-01-30 | s390/zcrypt: add new low level ep11 functions support file | Harald Freudenberger | |
This patch introduces two new files which provide some low level functions to interact with EP11 crypto cards: ep11_get_card_info() sends an EP11 query module info CPRB to the addressed card, processes the returning reply and exposes some of the information returned in the new ep11_card_info struct. ep11_get_domain_info() sends an EP11 query domain info CPRB to the addressed card/queue, processes the returning reply and exposes some of the information returned in the new ep11_domain_info struct.

2020-01-30 | s390/zcrypt: enable card/domain autoselect on ep11 cprbs | Harald Freudenberger | |
For EP11 CPRBs there was only to choose between specify one or more ep11 targets or not give a target at all. Without any target the zcrypt code assumed AUTOSELECT. For EP11 this ended up in choosing any EP11 APQN with regards to the weight. However, CCA CPRBs can have a more fine granular target addressing. The caller can give 0xFFFF as AUTOSELECT for the card and/or the domain. So it's possible to address any card but domain given or any domain but card given. This patch now introduces the very same for EP11 CPRB handling. An EP11 target entry now may contain 0xFFFF as card and/or domain value with the meaning of ANY card or domain. So now the same behavior as with CCA CPRBs becomes possible: Address any card with given domain or address any domain within given card. For convenience the zcrypt.h header file now has two new defines AUTOSEL_AP and AUTOSEL_DOM covering the 0xFFFF value to address card any and domain any.

2020-01-30 | s390/pkey: Add support for key blob with clear key value | Harald Freudenberger | |
This patch adds support for a new key blob format to the pkey kernel module. The new key blob comprises a clear key value together with key type information. The implementation tries to derive an protected key from the blob with the clear key value inside with 1) the PCKMO instruction. This may fail as the LPAR profile may disable this way. 2) Generate an CCA AES secure data key with exact the clear key value. This requires to have a working crypto card in CCA Coprocessor mode. Then derive an protected key from the CCA AES secure key again with the help of a working crypto card in CCA mode. If both way fail, the transformation of the clear key blob into a protected key will fail. For the PAES cipher this would result in a failure at setkey() invocation. A clear key value exposed in main memory is a security risk. The intention of this new 'clear key blob' support for pkey is to provide self-tests for the PAES cipher key implementation. These known answer tests obviously need to be run with well known key values. So with the clear key blob format there is a way to provide knwon answer tests together with an pkey clear key blob for the in-kernel self tests done at cipher registration.

2020-01-26 | s390/qeth: make cmd/reply matching more flexible | Julian Wiedmann | |
When data is received on the READ channel, the matching logic for cmds that are waiting for a reply is currently hard-coded into the channel's main IO callback. Move this into a per-cmd callback, so that we can apply custom matching logic for each individual cmd. This also allows us to remove the coarse-grained check for unexpected non-IPA replies, since they will no longer match against _all_ pending cmds. Note that IDX cmds use _no_ matcher, since their reply is synchronously received as part of the cmd's IO. Signed-off-by: Julian Wiedmann <jwi@linux.ibm.com> Signed-off-by: David S.

2020-01-09 | s390/zcrypt: move ap device reset from bus to driver code | Harald Freudenberger | |
This patch moves the reset invocation of an ap device when fresh detected from the ap bus to the probe() function of the driver responsible for this device. The virtualisation of ap devices makes it necessary to remove unconditioned resets on fresh appearing apqn devices. It may be that such a device is already enabled for guest usage. So there may be a race condition between host ap bus and guest ap bus doing the reset. This patch moves the reset from the ap bus to the zcrypt drivers. So if there is no zcrypt driver bound to an ap device - for example the ap device is bound to the vfio device driver - the ap device is untouched passed to the vfio device driver.

2019-12-24 | s390/qeth: fix initialization on old HW | Julian Wiedmann | |
I stumbled over an old OSA model that claims to support DIAG_ASSIST, but then rejects the cmd to query its DIAG capabilities. In the old code this was ok, as the returned raw error code was > 0. Now that we translate the raw codes to errnos, the "rc < 0" causes us to fail the initialization of the device. The fix is trivial: don't bail out when the DIAG query fails. Such an error is not critical, we can still use the device (with a slightly reduced set of features).

2019-12-24 | s390/qeth: Fix vnicc_is_in_use if rx_bcast not set | Alexandra Winter | |
Symptom: After vnicc/rx_bcast has been manually set to 0, bridge_* sysfs parameters can still be set or written. Only occurs on HiperSockets, as OSA doesn't support changing rx_bcast. Vnic characteristics and bridgeport settings are mutually exclusive. rx_bcast defaults to 1, so manually setting it to 0 should disable bridge_* parameters. Instead it makes sense here to check the supported mask. If the card does not support vnicc at all, bridge commands are always allowed.

2019-12-24 | s390/qeth: fix false reporting of VNIC CHAR config failure | Alexandra Winter | |
Symptom: Error message "Configuring the VNIC characteristics failed" in dmesg whenever an OSA interface on z15 is set online. The VNIC characteristics get re-programmed when setting a L2 device online. This follows the selected 'wanted' characteristics - with the exception that the INVISIBLE characteristic unconditionally gets switched off. For devices that don't support INVISIBLE (ie. OSA), the resulting IO failure raises a noisy error message ("Configuring the VNIC characteristics failed"). For IQD, INVISIBLE is off by default anyways. So don't unnecessarily special-case the INVISIBLE characteristic, and thereby suppress the misleading error message on OSA devices.

2019-12-24 | s390/qeth: fix qdio teardown after early init error | Julian Wiedmann | |
qeth_l?_set_online() goes through a number of initialization steps, and on any error uses qeth_l?_stop_card() to tear down the residual state. The first initialization step is qeth_core_hardsetup_card(). When this fails after having established a QDIO context on the device (ie. somewhere after qeth_mpc_initialize()), qeth_l?_stop_card() doesn't shut down this QDIO context again (since the card state hasn't progressed from DOWN at this stage). Even worse, we then call qdio_free() as final teardown step to free the QDIO data structures - while some of them are still hooked into wider QDIO infrastructure such as the IRQ list. This is inevitably followed by use-after-frees and other nastyness. Fix this by unconditionally calling qeth_qdio_clear_card() to shut down the QDIO context, and also to halt/clear any pending activity on the various IO channels. Remove the naive attempt at handling the teardown in qeth_mpc_initialize(), it clearly doesn't suffice and we're handling it properly now in the wider teardown code.

2019-12-20 | s390/qeth: fix promiscuous mode after reset | Julian Wiedmann | |
When managing the promiscuous mode during an RX modeset, qeth caches the current HW state to avoid repeated programming of the same state on each modeset. But while tearing down a device, we forget to clear the cached state. So when the device is later set online again, the initial RX modeset doesn't program the promiscuous mode since we believe it is already enabled. Fix this by clearing the cached state in the tear-down path. Note that for the SBP variant of promiscuous mode, this accidentally works right now because we unconditionally restore the SBP role while re-initializing.

Though, the comment for this function describes a negative return value to indicate failures. As a result, the DASD device driver interprets the return value of ccw_device_get_mdc() incorrectly. The error case is essentially a dead code path. To fix this behaviour, check explicitly for a return value of 0 and change the comment for ccw_device_get_mdc() accordingly. This fix merely enables the error code path in the DASD functions get_fcx_max_data() and verify_fcx_max_data(). The actual functionality stays the same and is still correct.

2019-12-18 | s390/qeth: don't raise NETDEV_REBOOT event from L3 offline path | Julian Wiedmann | |
This is a leftover from back when a recovery action didn't go through dev_close(), and was meant to shoot down all remaining af_iucv sockets on the interface. Now that the offline path always calls dev_close(), the NETDEV_GOING_DOWN event from __dev_close_many() is sufficient and this hack can be removed.

2019-12-18 | s390/qeth: overhaul L3 IP address dump code | Julian Wiedmann | |
The current code that dumps the RXIP/VIPA/IPATO addresses via sysfs first checks whether the buffer still provides sufficient space to hold another formatted address. But the maximum length of an formatted IPv4 address is 15 characters, not 12. So we underestimate the max required length and if the buffer was previously filled to _just_ the right level, a formatted address can end up being truncated. Revamp these code paths to use the _actually_ required length of the formatted IP address, and while at it suppress a gratuitous newline. Also use scnprintf() to format the output. In case of a truncation, this would allow us to return the number of characters that were actually written. Signed-off-by: Julian Wiedmann <jwi@linux.ibm.com> Signed-off-by: David S.

2019-12-18 | s390/qeth: wake up all waiters from qeth_irq() | Julian Wiedmann | |
card->wait_q is shared by different users, for different wake-up conditions. qeth_irq() can potentially trigger multiple of these conditions: 1) A change to channel->irq_pending, which qeth_send_control_data() is waiting for. 2) A change to card->state, which qeth_clear_channel() and qeth_halt_channel() are waiting for. As qeth_irq() does only a single wake_up(), we might miss to wake up a second eligible waiter. Luckily all waiters are guarded with a timeout, so this situation should recover on its own eventually. To make things work robustly, add an additional wake_up() for changes to channel->state. And extract a helper that updates channel->irq_pending along with the needed wake_up().

2019-12-18 | s390/qeth: only handle IRQs while device is online | Julian Wiedmann | |
A qeth device that's offline should not be receiving any IRQs - all pending IOs have been terminated, and we avoid starting any new ones. So rather than immediately registering the IRQ handler when the device is probed, only register it while the device is online.
