* [S390]: Fix use of skb after netif_rxJulia Lawall2007-12-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Recently, Wang Chen submitted a patch (d30f53aeb31d453a5230f526bea592af07944564) to move a call to netif_rx(skb) after a subsequent reference to skb, because netif_rx may call kfree_skb on its argument. netif_rx_ni calls netif_rx, so the same problem occurs in the files below. I have left the updating of dev->last_rx after the calls to netif_rx_ni because it seems time dependent, but moved the other field updates before. This was found using the following semantic match. (http://www.emn.fr/x-info/coccinelle/) // <smpl> @@ expression skb, e,e1; @@ ( netif_rx(skb); | netif_rx_ni(skb); ) ... when != skb = e ( skb = e1 | * skb ) // </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Signed-off-by: David S.

| * [S390] dcssblk: prevent early access without own make_request functionChristian Borntraeger2007-12-04
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When loading a dcss segment with the dcssblk driver, sometimes the following kind of message appears: bio too big device dcssblk0 (8 > 0) Buffer I/O error on device dcssblk0, logical block 172016 .. The fix is to move the disk registration after setting the make_request function, to avoid calls into generic_make_request for dcssblock without having the make_request function set up properly.

| | | | | | | | | | | | | | | | | | | | | | | | | | We may receive a unit check for every path when we issue a SenseID. Unfortunately, the channel subsystem will try on a different path every time if we use a lpm of 0xff, which will exhaust our retry counter. Therefore, revert SenseID to its previous per-path behaviour and just leave out the suspend multipath reconnect.

Instead it should just go through the down() operation, which balances the first up(), and run through zfcp_erp_strategy one more time for the second up(), which eventually cleans up erp_action. Which is similar to the normal processing of an event for erp_action doing something asynchronously (e.g. waiting for the completion of an fsf_req). This only works if we make sure that a dismissed erp_action is passed to zfcp_erp_strategy() prior to the other action, which caused actions to be dismissed. Therefore the patch implements this rule: running actions go to the head of the ready list; new actions go to the tail of the ready list; the erp thread picks actions to be processed from the ready list's head.

| * [SCSI] zfcp: fix dismissal of error recovery actionsMartin Peschke2007-11-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | zfcp_erp_action_dismiss() used to ignore any actions in the ready list. This is a bug. Any action superseded by a stronger action needs to be dismissed. This patch changes zfcp_erp_action_dismiss() so that it dismisses actions regardless of their list affiliation. The ERP thread is able to handle this. It is important to kick the erp thread only for actions in the running list, though, as an imbalance of wakeup signals would confuse the erp thread otherwise.

* [S390] Fix smsgiucv init on no iucv machinesChristian Borntraeger2007-11-05
| | | | | | | | | | | | | | | | | smsgiucv is a driver that relies on iucv to work properly. If iucv ans smsgiucv are compiled into the kernel and run on an lpar the following scenario happens: iucv is initialized early as a subsystem. It checks for z/VM and returns with EPROTONOTSUPPORT. Later smsgiucv tries to run driver_register with iucv_bus as bus. As this bus is not initialized the driver core and list debugging issue several warnings and oopses. Solution is to let smsgiucv also check for z/VM and return EPROTONOTSUPPORT as well.

| * | Driver core: change add_uevent_var to use a structKay Sievers2007-10-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This changes the uevent buffer functions to use a struct instead of a long list of parameters. It does no longer require the caller to do the proper buffer termination and size accounting, which is currently wrong in some places. It fixes a known bug where parts of the uevent environment are overwritten because of wrong index calculations. Many thanks to Mathieu Desnoyers for finding bugs and improving the error handling.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The early console device is special as it already has all needed data set and raw3215[0] allocated from con3215_init(). Therefore, it needs special treatment in the probe function so it can be matched with the 3215 driver which is already owning it.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently there are situations, where the tape medium state (loaded, unloaded, unknown) is not set correctly. The reason is that the medium association field is used to determine the medium state. This not always leads to correct results. To fix that we use another field of the medium sense data instead.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | memcpy_real uses the mvcle instruction. This instruction alters all used registers (source, destination and 2 x count). Therefore we have to flag those registers as input/output registers (+d). In addition to that, we have to specify, that we read from memory designated by "src" and write to memory designated by "dest".
