2009-09-11[S390] tape: Fix device online messagesMichael Holzheu
Currently, when a tape device is set online and no cartridge is loaded, we get the messages "The tape cartridge has been successfully unloaded" and "Determining the size of the recorded area". These messages are not correct. To fix this, we now print the "cartridge loaded/unloaded" messages only, when the load/unload event really occurs. In addition to that, the message "Determining the size of the recorded area" is only printed, if a cartridge is loaded.

2009-09-11[S390] xpram: Remove checksum validation for suspend/resumeMichael Holzheu
Currently in the suspend process checksums for the XPRAM partitions are created and stored. During the resume process it is checked, if the checksums are still the same. If this is not the case, a kernel panic is triggered. Unfortunately this prevents XPRAM from beeing used as suspend device, because in this case after the checksum has been created, the memory image is written to XPRAM and therefore the contents of the suspend partition is changed. In order to allow XPRAM to be used as suspend device, this patch removes the checksum validation.

2009-09-11[S390] vmur: Invalid allocation sequence for vmur classMichael Holzheu
The vmur class is allocated after the CCW driver is registered and it is destroyed before the CCW driver is unregistered. This is not the correct sequence, because the vmur class can be used via driver core callbacks that are triggered during the CCW driver deregistration. For Example: 1. vmur device is online 2. vmur module is unloaded This leads to the following function call stack: <4> [<0000000000387286>] device_destroy+0x36/0x5c <4> [<000003e000209714>] ur_set_offline_force+0x9c/0x10c [vmur] <4> [<000003e00020a928>] ur_remove+0x64/0xbc [vmur] <4> [<00000000003e4d2e>] ccw_device_remove+0x42/0x1ac <4> [<000000000038a1aa>] __device_release_driver+0x9a/0xe4 <4> [<000000000038a2da>] driver_detach+0xe6/0xec <4> [<0000000000388ee4>] bus_remove_driver+0xc0/0x108 <4> [<000003e00020ad5a>] ur_exit+0x52/0x84 [vmur] In device_destroy() the vmur class is used. Since it is already freed, this can lead to a kernel panic. To fix the problem, the vmur class has to be allocated before the CCW driver is registered and destroyed after the CCW driver has ben unregistered.

2009-09-11[S390] cio: remove ccw_device init_nameSebastian Ott
We used the init_name to set the console ccw_device's name early at the boot stage. This patch moves the name setting (for all ccw devices) to the point where we actually register the device. At this time we can do dynamic allocations and therefore use dev_set_name. Signed-off-by: Sebastian Ott <sebott@linux.vnet.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
2009-09-11[S390] cio: move final put_device to ccw_device_unregisterSebastian Ott
We use a test_and_clear_bit to prevent a device from being unregistered twice. Unfortunately in this cases the "final" put_device (from device_initialize) was issued more than once, resulting in an use after free error.

2009-09-11[S390] cio: remove subchannel init_nameSebastian Ott
We used the init_name to set the console subchannels name early at the boot stage. With the patch cio: fix memleak in subchannel validation we moved the name setting to the point where we actually register the console subchannel.

2009-09-11[S390] cio: fix memleak in subchannel validationSebastian Ott
When scanning for new subchannels we have a code path where we allocate memory for a struct subchannel, set the device name (which is dynamically allocated now) and do a check if the underlying device is blacklisted - if so we free the subchannel structure. Since we have not set up refcounting at this stage, the device name's memory is lost. Fix this by moving the dev_set_name after the blacklist test. Note: With this patch the init_name for the console subchannel becomes virtually obsolete.

2009-09-11[S390] cio: fix use after free in s390 debug featureSebastian Ott
When using s390dbf with "%s" in sprintf format strings the string itself is not copied to the dbf buffer. Since in this case only pointers are stored in the s390dbf, we should not use dev_name - which is bound to the lifetime of the device. Reading this entry from s390dbf after the device was released will cause an use after free error.

2009-09-11[S390] cio: failing set online/offline processing.Michael Ernst
When unit checks trigger sensing the device state is set to W4SENSE until sense completion; then the device state is set back to ONLINE. If a unit check occurs while set online or set offline requests are processed then it might happen that the device's temporary W4SENSE state causes these functions to terminate, leaving the device in an inconsistent state when the state is set back to ONLINE later on so that the device cannot be set online or offline any longer. To solve this, set online/offline and related rollback or error routines are processed only if the device is in a final or DISCONNECTED state.

Path verification events occurring for offline devices are currently ignored.

2009-09-11drivers/ata: use resource_sizeJulia Lawall
Use the function resource_size, which reduces the chance of introducing off-by-one errors in calculating the resource size. The semantic patch that makes this change is as follows: (http://www.emn.fr/x-info/coccinelle/) // <smpl> @@ struct resource *res; @@ - (res->end - res->start) + 1 + resource_size(res) // </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Cc: Jeff Garzik <jeff@garzik.org> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>

2009-09-10md: Fix "strchr" [drivers/md/dm-log-userspace.ko] undefined!Geert Uytterhoeven
Commit b8313b6da7e2e7c7f47d93d8561969a3ff9ba0ea ("dm log: remove incorrect field from userspace table output") added a call to strstr() with a single-character "needle" string parameter. Unfortunately some versions of gcc replace such calls to strstr() by calls to strchr() behind our back. This causes linking errors if strchr() is defined as an inline function in <asm/string.h> (e.g. on m68k): | WARNING: "strchr" [drivers/md/dm-log-userspace.ko] undefined! Avoid this by explicitly calling strchr() instead. Signed-off-by: Geert Uytterhoeven <geert@linux-m68k.org> Cc: stable@kernel.org Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2009-09-10TPM: Fixup boot probe timeout for tpm_tis driverJason Gunthorpe
When probing the device in tpm_tis_init the call request_locality uses timeout_a, which wasn't being initalized until after request_locality. This results in request_locality falsely timing out if the chip is still starting. Move the initialization to before request_locality. This probably only matters for embedded cases (ie mine), a BIOS likely gets the TPM into a state where this code path isn't necessary.
