We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it.

include cleanup: Update gfp.h and slab.h includes to prepare for breaking implicit slab.h inclusion from percpu.h percpu.h is included by sched.h and module.h and thus ends up being included when building most .c files. percpu.h includes slab.h which in turn includes gfp.h making everything defined by the two files universally available and complicating inclusion dependencies. percpu.h -> slab.h dependency is about to be removed. Prepare for this change by updating users of gfp and slab facilities include those headers directly instead of assuming availability. As this conversion needs to touch large number of source files, the following script is used as the basis of conversion. http://userweb.kernel.org/~tj/misc/slabh-sweep.py The script does the followings. * Scan files for gfp and slab usages and update includes such that only the necessary includes are there. ie. if only gfp is used, gfp.h, if slab is used, slab.h. * When the script inserts a new include, it looks at the include blocks and try to put the new include such that its order conforms to its surrounding. It's put in the include block which contains core kernel includes, in the same order that the rest are ordered - alphabetical, Christmas tree, rev-Xmas-tree or at the end if there doesn't seem to be any matching order. * If the script can't find a place to put a new include (mostly because the file doesn't have fitting include block), it prints out an error message indicating which .h file needs to be added to the file. The conversion was done in the following steps. 1. The initial automatic conversion of all .c files updated slightly over 4000 files, deleting around 700 includes and adding ~480 gfp.h and ~3000 slab.h inclusions. The script emitted errors for ~400 files. 2. Each error was manually checked. Some didn't need the inclusion, some needed manual addition while adding it to implementation .h or embedding .c file was more appropriate for others. This step added inclusions to around 150 files. 3. The script was run again and the output was compared to the edits from #2 to make sure no file was left behind. 4. Several build tests were done and a couple of problems were fixed. e.g. lib/decompress_*.c used malloc/free() wrappers around slab APIs requiring slab.h to be added manually. 5. The script was run on all .h files but without automatically editing them as sprinkling gfp.h and slab.h inclusions around .h files could easily lead to inclusion dependency hell. Most gfp.h inclusion directives were ignored as stuff from gfp.h was usually wildly available and often used in preprocessor macros. Each slab.h inclusion directive was examined and added manually as necessary. 6. percpu.h was updated not to include slab.h. 7. Build test were done on the following configurations and failures were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my distributed build env didn't work with gcov compiles) and a few more options had to be turned off depending on archs to make things build (like ipr on powerpc/64 which failed due to missing writeq). * x86 and x86_64 UP and SMP allmodconfig and a custom test config. * powerpc and powerpc64 SMP allmodconfig * sparc and sparc64 SMP allmodconfig * ia64 SMP allmodconfig * s390 SMP allmodconfig * alpha SMP allmodconfig * um on x86_64 SMP allmodconfig 8. percpu.h modifications were reverted so that it could be applied as a separate patch and serve as bisection point. Given the fact that I had only a couple of failures from tests on step 6, I'm fairly confident about the coverage of this conversion patch. If there is a breakage, it's likely to be something in one of the arch headers which should be easily discoverable easily on most builds of the specific arch.

ipr: Reboot speed improvements Currently when performing a reboot with an ipr adapter, the adapter gets shutdown completely, flushing all write cache, as well as performing a full hardware reset of the card during the shutdown phase of the old kernel. This ensures the adapter is in a fully quiesced state across the reboot. There are scenarios, however, such as when performing kexec, where this full adapter shutdown is not required and not desired, since it can make the reboot process take noticeably longer. This patch adds a module parameter to allow for skipping the full shutdown during reboot. Rather than performing a full adapter shutdown and reset, we simply cancel any outstanding error buffers, place the adapter into a state where it has no memory of any DMA addresses from the old kernel, then disable the device. This significantly speeds up kexec boot, particularly in configurations with multiple ipr adapters.

ipr: Reboot speed improvements Currently when performing a reboot with an ipr adapter, the adapter gets shutdown completely, flushing all write cache, as well as performing a full hardware reset of the card during the shutdown phase of the old kernel. This ensures the adapter is in a fully quiesced state across the reboot. There are scenarios, however, such as when performing kexec, where this full adapter shutdown is not required and not desired, since it can make the reboot process take noticeably longer. This patch adds a module parameter to allow for skipping the full shutdown during reboot. Rather than performing a full adapter shutdown and reset, we simply cancel any outstanding error buffers, place the adapter into a state where it has no memory of any DMA addresses from the old kernel, then disable the device. This significantly speeds up kexec boot, particularly in configurations with multiple ipr adapters.

ipr: wait for aborted command responses Fixes a race condition in abort handling that was injected when multiple interrupt support was added. When only a single interrupt is present, the adapter guarantees it will send responses for aborted commands prior to the response for the abort command itself. With multiple interrupts, these responses generally come back on different interrupts, so we need to ensure the abort thread waits until the aborted command is complete so we don't perform a double completion. This race condition was being hit frequently in environments which were triggering command timeouts, which was resulting in a double completion causing a kernel oops.

ipr: wait for aborted command responses Fixes a race condition in abort handling that was injected when multiple interrupt support was added. When only a single interrupt is present, the adapter guarantees it will send responses for aborted commands prior to the response for the abort command itself. With multiple interrupts, these responses generally come back on different interrupts, so we need to ensure the abort thread waits until the aborted command is complete so we don't perform a double completion. This race condition was being hit frequently in environments which were triggering command timeouts, which was resulting in a double completion causing a kernel oops.

ipr: Fix invalid array indexing for HRRQ Fixes another signed / unsigned array indexing bug in the ipr driver. Currently, when hrrq_index wraps, it becomes a negative number. We do the modulo, but still have a negative number, so we end up indexing backwards in the array. Given where the hrrq array is located in memory, we probably won't actually reference memory we don't own, but nonetheless ipr is still looking at data within struct ipr_ioa_cfg and interpreting it as struct ipr_hrr_queue data, so bad things could certainly happen. Each ipr adapter has anywhere from 1 to 16 HRRQs. By default, we use 2 on new adapters. Let's take an example: Assume ioa_cfg->hrrq_index=0x7fffffffe and ioa_cfg->hrrq_num=4: The atomic_add_return will then return -1. We mod this with 3 and get -2, add one and get -1 for an array index. On adapters which support more than a single HRRQ, we dedicate HRRQ to adapter initialization and error interrupts so that we can optimize the other queues for fast path I/O. So all normal I/O uses HRRQ 1-15. So we want to spread the I/O requests across those HRRQs. With the default module parameter settings, this bug won't hit, only when someone sets the ipr.number_of_msix parameter to a value larger than 3 is when bad things start to happen.

[SCSI] ipr: Support new device queueing model New ipr adapters support a new device queueing model in the adapter firmware. The queueing model is the NACA queueing model, but it does not mean use of NACA is required. The new model removes some of the adapter firmware queue state that made handling QERR=0 almost impossible. The queueing model on older adapters included the concept of a queue frozen state, which would freeze the response queue in the adapter when a check condition occurred, requiring a a primitive to resume the queue. The new queueing model removes this complexity. Signed-off-by: Brian King <brking@us.ibm.com> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>

[SCSI] ipr: fix resource type update and add sdev and shost attributes Setting the resource type in the ipr_update_res_entry function was incorrect in that the top 4 bits were masked off. The assignment has been updated to no longer mask those bits. Then, two new attributes were added to allow the user space utilities to more easily get information. The resource_type sdev attribute is set for all devices in the adapter's configuration table and indicates the type of device. The fw_type shost attribute indicates the firmware type supported by the adapter. Finally, the resource_path attribute was changed to be mode S_IRUGO.

ipr: Reboot speed improvements Currently when performing a reboot with an ipr adapter, the adapter gets shutdown completely, flushing all write cache, as well as performing a full hardware reset of the card during the shutdown phase of the old kernel. This ensures the adapter is in a fully quiesced state across the reboot. There are scenarios, however, such as when performing kexec, where this full adapter shutdown is not required and not desired, since it can make the reboot process take noticeably longer. This patch adds a module parameter to allow for skipping the full shutdown during reboot. Rather than performing a full adapter shutdown and reset, we simply cancel any outstanding error buffers, place the adapter into a state where it has no memory of any DMA addresses from the old kernel, then disable the device. This significantly speeds up kexec boot, particularly in configurations with multiple ipr adapters.

ipr: Reboot speed improvements Currently when performing a reboot with an ipr adapter, the adapter gets shutdown completely, flushing all write cache, as well as performing a full hardware reset of the card during the shutdown phase of the old kernel. This ensures the adapter is in a fully quiesced state across the reboot. There are scenarios, however, such as when performing kexec, where this full adapter shutdown is not required and not desired, since it can make the reboot process take noticeably longer. This patch adds a module parameter to allow for skipping the full shutdown during reboot. Rather than performing a full adapter shutdown and reset, we simply cancel any outstanding error buffers, place the adapter into a state where it has no memory of any DMA addresses from the old kernel, then disable the device. This significantly speeds up kexec boot, particularly in configurations with multiple ipr adapters.

scsi: ipr: Add asynchronous error notification This patch implements functions for pushing HCAM (host controlled asynchronous messages) error buffers to userspace through sysfs attributes. Reads to the "async_err_log" attribute will result in a single HCAM buffer being copied to userspace; one can process the next HCAM buffer by writing any string to the same attribute. A new list was added to the ioa_cfg structure to store the HCAM buffers for later reporting. We also send a KOBJ_CHANGE event whenever a new HCAM buffer is made available to userspace.

[SCSI] ipr: Stop reading adapter dump prematurely When the ipr driver decides to dump the adapter, it changes the sdt_state to GET_DUMP, then prepares the adapter so that the dump can be read. However, if the ipr worker thread wakes up for some reason before the driver has put the adapter in a state where it can succesfully dump the adapter, the driver will start dumping the adapter too early, which can potentially trigger a BUG check in the pci config blocking API. Fix this by adding a new sdt_state to differentiate between the ipr driver wanting to dump the adapter in the near future and wanting to dump the adapter now.

[SCSI] ipr: Stop reading adapter dump prematurely When the ipr driver decides to dump the adapter, it changes the sdt_state to GET_DUMP, then prepares the adapter so that the dump can be read. However, if the ipr worker thread wakes up for some reason before the driver has put the adapter in a state where it can succesfully dump the adapter, the driver will start dumping the adapter too early, which can potentially trigger a BUG check in the pci config blocking API. Fix this by adding a new sdt_state to differentiate between the ipr driver wanting to dump the adapter in the near future and wanting to dump the adapter now.

[SCSI] ipr: Fix BUG on adapter dump timeout If an adapter dump times out, the ipr driver will abort the dump and proceed to reset and recover the adapter. When an adapter dump completes, the work thread which is reading the adapter dump will initiate an adapter reset to recover the adapter. However, when the adapter dump gets aborted, the work thread should not initiate an adapter reset, since an adapter reset is already in progress. This fixes a case of calling pci_block_user_cfg_access overlapped, which results in a BUG.

scsi: ipr: System hung while dlpar adding primary ipr adapter back While dlpar adding primary ipr adapter back, driver goes through adapter initialization then schedule ipr_worker_thread to start te disk scan by dropping the host lock, calling scsi_add_device. Then get the adapter reset request again, so driver does scsi_block_requests, this will cause the scsi_add_device get hung until we unblock. But we can't run ipr_worker_thread to do the unblock because its stuck in scsi_add_device. This patch fixes the issue.

sysfs: add parameter "struct bin_attribute *" in .read/.write methods for sysfs binary attributes Well, first of all, I don't want to change so many files either. What I do: Adding a new parameter "struct bin_attribute *" in the .read/.write methods for the sysfs binary attributes. In fact, only the four lines change in fs/sysfs/bin.c and include/linux/sysfs.h do the real work. But I have to update all the files that use binary attributes to make them compatible with the new .read and .write methods. I'm not sure if I missed any. :( Why I do this: For a sysfs attribute, we can get a pointer pointing to the struct attribute in the .show/.store method, while we can't do this for the binary attributes. I don't know why this is different, but this does make it not so handy to use the binary attributes as the regular ones. So I think this patch is reasonable. :) Who benefits from it: The patch that exposes ACPI tables in sysfs requires such an improvement. All the table binary attributes share the same .read method. Parameter "struct bin_attribute *" is used to get the table signature and instance number which are used to distinguish different ACPI table binary attributes. Without this parameter, we need to offer different .read methods for different ACPI table binary attributes. This is impossible as there are various ACPI tables on different platforms, and we don't know what they are until they are loaded.

The assignment has been updated to no longer mask those bits. Then, two new attributes were added to allow the user space utilities to more easily get information. The resource_type sdev attribute is set for all devices in the adapter's configuration table and indicates the type of device. The fw_type shost attribute indicates the firmware type supported by the adapter. Finally, the resource_path attribute was changed to be mode S_IRUGO.

scsi: ipr: Add asynchronous error notification This patch implements functions for pushing HCAM (host controlled asynchronous messages) error buffers to userspace through sysfs attributes. Reads to the "async_err_log" attribute will result in a single HCAM buffer being copied to userspace; one can process the next HCAM buffer by writing any string to the same attribute. A new list was added to the ioa_cfg structure to store the HCAM buffers for later reporting. We also send a KOBJ_CHANGE event whenever a new HCAM buffer is made available to userspace.

[SCSI] ipr: fix resource type update and add sdev and shost attributes Setting the resource type in the ipr_update_res_entry function was incorrect in that the top 4 bits were masked off. The assignment has been updated to no longer mask those bits. Then, two new attributes were added to allow the user space utilities to more easily get information. The resource_type sdev attribute is set for all devices in the adapter's configuration table and indicates the type of device. The fw_type shost attribute indicates the firmware type supported by the adapter. Finally, the resource_path attribute was changed to be mode S_IRUGO.

sysfs: add parameter "struct bin_attribute *" in .read/.write methods for sysfs binary attributes Well, first of all, I don't want to change so many files either. What I do: Adding a new parameter "struct bin_attribute *" in the .read/.write methods for the sysfs binary attributes. In fact, only the four lines change in fs/sysfs/bin.c and include/linux/sysfs.h do the real work. But I have to update all the files that use binary attributes to make them compatible with the new .read and .write methods. I'm not sure if I missed any. :( Why I do this: For a sysfs attribute, we can get a pointer pointing to the struct attribute in the .show/.store method, while we can't do this for the binary attributes. I don't know why this is different, but this does make it not so handy to use the binary attributes as the regular ones. So I think this patch is reasonable. :) Who benefits from it: The patch that exposes ACPI tables in sysfs requires such an improvement. All the table binary attributes share the same .read method. Parameter "struct bin_attribute *" is used to get the table signature and instance number which are used to distinguish different ACPI table binary attributes. Without this parameter, we need to offer different .read methods for different ACPI table binary attributes. This is impossible as there are various ACPI tables on different platforms, and we don't know what they are until they are loaded.

treewide: Use array_size() in vmalloc() The vmalloc() function has no 2-factor argument form, so multiplication factors need to be wrapped in array_size(). This patch replaces cases of: vmalloc(a * b) with: vmalloc(array_size(a, b)) as well as handling cases of: vmalloc(a * b * c) with: vmalloc(array3_size(a, b, c)) This does, however, attempt to ignore constant size factors like: vmalloc(4 * 1024) though any constants defined via macros get caught up in the conversion. Any factors with a sizeof() of "unsigned char", "char", and "u8" were dropped, since they're redundant. The Coccinelle script used for this was: // Fix redundant parens around sizeof(). @@ type TYPE; expression THING, E; @@ ( vmalloc( - (sizeof(TYPE)) * E + sizeof(TYPE) * E , ...) | vmalloc( - (sizeof(THING)) * E + sizeof(THING) * E , ...) ) // Drop single-byte sizes and redundant parens. @@ expression COUNT; typedef u8; typedef __u8; @@ ( vmalloc( - sizeof(u8) * (COUNT) + COUNT , ...) | vmalloc( - sizeof(__u8) * (COUNT) + COUNT , ...) | vmalloc( - sizeof(char) * (COUNT) + COUNT , ...) | vmalloc( - sizeof(unsigned char) * (COUNT) + COUNT , ...) | vmalloc( - sizeof(u8) * COUNT + COUNT , ...) | vmalloc( - sizeof(__u8) * COUNT + COUNT , ...) | vmalloc( - sizeof(char) * COUNT + COUNT , ...) | vmalloc( - sizeof(unsigned char) * COUNT + COUNT , ...) ) // 2-factor product with sizeof(type/expression) and identifier or constant. @@ type TYPE; expression THING; identifier COUNT_ID; constant COUNT_CONST; @@ ( vmalloc( - sizeof(TYPE) * (COUNT_ID) + array_size(COUNT_ID, sizeof(TYPE)) , ...) | vmalloc( - sizeof(TYPE) * COUNT_ID + array_size(COUNT_ID, sizeof(TYPE)) , ...) | vmalloc( - sizeof(TYPE) * (COUNT_CONST) + array_size(COUNT_CONST, sizeof(TYPE)) , ...) | vmalloc( - sizeof(TYPE) * COUNT_CONST + array_size(COUNT_CONST, sizeof(TYPE)) , ...) | vmalloc( - sizeof(THING) * (COUNT_ID) + array_size(COUNT_ID, sizeof(THING)) , ...) | vmalloc( - sizeof(THING) * COUNT_ID + array_size(COUNT_ID, sizeof(THING)) , ...) | vmalloc( - sizeof(THING) * (COUNT_CONST) + array_size(COUNT_CONST, sizeof(THING)) , ...) | vmalloc( - sizeof(THING) * COUNT_CONST + array_size(COUNT_CONST, sizeof(THING)) , ...) ) // 2-factor product, only identifiers. @@ identifier SIZE, COUNT; @@ vmalloc( - SIZE * COUNT + array_size(COUNT, SIZE) , ...) // 3-factor product with 1 sizeof(type) or sizeof(expression), with // redundant parens removed. @@ expression THING; identifier STRIDE, COUNT; type TYPE; @@ ( vmalloc( - sizeof(TYPE) * (COUNT) * (STRIDE) + array3_size(COUNT, STRIDE, sizeof(TYPE)) , ...) | vmalloc( - sizeof(TYPE) * (COUNT) * STRIDE + array3_size(COUNT, STRIDE, sizeof(TYPE)) , ...) | vmalloc( - sizeof(TYPE) * COUNT * (STRIDE) + array3_size(COUNT, STRIDE, sizeof(TYPE)) , ...) | vmalloc( - sizeof(TYPE) * COUNT * STRIDE + array3_size(COUNT, STRIDE, sizeof(TYPE)) , ...) | vmalloc( - sizeof(THING) * (COUNT) * (STRIDE) + array3_size(COUNT, STRIDE, sizeof(THING)) , ...) | vmalloc( - sizeof(THING) * (COUNT) * STRIDE + array3_size(COUNT, STRIDE, sizeof(THING)) , ...) | vmalloc( - sizeof(THING) * COUNT * (STRIDE) + array3_size(COUNT, STRIDE, sizeof(THING)) , ...) | vmalloc( - sizeof(THING) * COUNT * STRIDE + array3_size(COUNT, STRIDE, sizeof(THING)) , ...) ) // 3-factor product with 2 sizeof(variable), with redundant parens removed. @@ expression THING1, THING2; identifier COUNT; type TYPE1, TYPE2; @@ ( vmalloc( - sizeof(TYPE1) * sizeof(TYPE2) * COUNT + array3_size(COUNT, sizeof(TYPE1), sizeof(TYPE2)) , ...) | vmalloc( - sizeof(TYPE1) * sizeof(THING2) * (COUNT) + array3_size(COUNT, sizeof(TYPE1), sizeof(TYPE2)) , ...) | vmalloc( - sizeof(THING1) * sizeof(THING2) * COUNT + array3_size(COUNT, sizeof(THING1), sizeof(THING2)) , ...) | vmalloc( - sizeof(THING1) * sizeof(THING2) * (COUNT) + array3_size(COUNT, sizeof(THING1), sizeof(THING2)) , ...) | vmalloc( - sizeof(TYPE1) * sizeof(THING2) * COUNT + array3_size(COUNT, sizeof(TYPE1), sizeof(THING2)) , ...) | vmalloc( - sizeof(TYPE1) * sizeof(THING2) * (COUNT) + array3_size(COUNT, sizeof(TYPE1), sizeof(THING2)) , ...) ) // 3-factor product, only identifiers, with redundant parens removed. @@ identifier STRIDE, SIZE, COUNT; @@ ( vmalloc( - (COUNT) * STRIDE * SIZE + array3_size(COUNT, STRIDE, SIZE) , ...) | vmalloc( - COUNT * (STRIDE) * SIZE + array3_size(COUNT, STRIDE, SIZE) , ...) | vmalloc( - COUNT * STRIDE * (SIZE) + array3_size(COUNT, STRIDE, SIZE) , ...) | vmalloc( - (COUNT) * (STRIDE) * SIZE + array3_size(COUNT, STRIDE, SIZE) , ...) | vmalloc( - COUNT * (STRIDE) * (SIZE) + array3_size(COUNT, STRIDE, SIZE) , ...) | vmalloc( - (COUNT) * STRIDE * (SIZE) + array3_size(COUNT, STRIDE, SIZE) , ...) | vmalloc( - (COUNT) * (STRIDE) * (SIZE) + array3_size(COUNT, STRIDE, SIZE) , ...) | vmalloc( - COUNT * STRIDE * SIZE + array3_size(COUNT, STRIDE, SIZE) , ...) ) // Any remaining multi-factor products, first at least 3-factor products // when they're not all constants... @@ expression E1, E2, E3; constant C1, C2, C3; @@ ( vmalloc(C1 * C2 * C3, ...) | vmalloc( - E1 * E2 * E3 + array3_size(E1, E2, E3) , ...) ) // And then all remaining 2 factors products when they're not all constants. @@ expression E1, E2; constant C1, C2; @@ ( vmalloc(C1 * C2, ...) | vmalloc( - E1 * E2 + array_size(E1, E2) , ...) ) Signed-off-by: Kees Cook <keescook@chromium.org>

sysfs: add parameter "struct bin_attribute *" in .read/.write methods for sysfs binary attributes Well, first of all, I don't want to change so many files either. What I do: Adding a new parameter "struct bin_attribute *" in the .read/.write methods for the sysfs binary attributes. In fact, only the four lines change in fs/sysfs/bin.c and include/linux/sysfs.h do the real work. But I have to update all the files that use binary attributes to make them compatible with the new .read and .write methods. I'm not sure if I missed any. :( Why I do this: For a sysfs attribute, we can get a pointer pointing to the struct attribute in the .show/.store method, while we can't do this for the binary attributes. I don't know why this is different, but this does make it not so handy to use the binary attributes as the regular ones. So I think this patch is reasonable. :) Who benefits from it: The patch that exposes ACPI tables in sysfs requires such an improvement. All the table binary attributes share the same .read method. Parameter "struct bin_attribute *" is used to get the table signature and instance number which are used to distinguish different ACPI table binary attributes. Without this parameter, we need to offer different .read methods for different ACPI table binary attributes. This is impossible as there are various ACPI tables on different platforms, and we don't know what they are until they are loaded.

This fixes an issue that can arise if a device is deleted via sysfs. If a new device is then physically added, it will use the previous device's target id. If the host is then rescanned, the device that had been deleted, since it is using the same target id as the new device is using, will never be found, resulting in a missing device. Fix this by only freeing the target id only if the resource is actually gone. Signed-off-by: Brian King <brking@linux.vnet.ibm.com> Signed-off-by: James Bottomley <JBottomley@Parallels.com>

[SCSI] ipr: Fix target id allocation re-use problem For the latest ipr SAS adapters, target id's are a completely logical construct that are managed in the ipr driver. This fixes an issue that can arise if a device is deleted via sysfs. If a new device is then physically added, it will use the previous device's target id. If the host is then rescanned, the device that had been deleted, since it is using the same target id as the new device is using, will never be found, resulting in a missing device. Fix this by only freeing the target id only if the resource is actually gone. Signed-off-by: Brian King <brking@linux.vnet.ibm.com> Signed-off-by: James Bottomley <JBottomley@Parallels.com>

libata: kill ATA_FLAG_DISABLED ATA_FLAG_DISABLED is only used by drivers which don't use ->error_handler framework and is largely broken. Its only meaningful function is to make irq handlers skip processing if the flag is set, which is largely useless and even harmful as it makes those ports more likely to cause IRQ storms. Kill ATA_FLAG_DISABLED and makes the callers disable attached devices instead. ata_port_probe() and ata_port_disable() which manipulate the flag are also killed. This simplifies condition check in IRQ handlers. While updating IRQ handlers, remove ap NULL check as libata guarantees consecutive port allocation (unoccupied ports are initialized with dummies) and long-obsolete ATA_QCFLAG_ACTIVE check (checked by ata_qc_from_tag()).

scsi: don't set tagging state from scsi_adjust_queue_depth Remove the tagged argument from scsi_adjust_queue_depth, and just let it handle the queue depth. For most drivers those two are fairly separate, given that most modern drivers don't care about the SCSI "tagged" status of a command at all, and many old drivers allow queuing of multiple untagged commands in the driver. Instead we start out with the ->simple_tags flag set before calling ->slave_configure, which is how all drivers actually looking at ->simple_tags except for one worke anyway. The one other case looks broken, but I've kept the behavior as-is for now. Except for that we only change ->simple_tags from the ->change_queue_type, and when rejecting a tag message in a single driver, so keeping this churn out of scsi_adjust_queue_depth is a clear win. Now that the usage of scsi_adjust_queue_depth is more obvious we can also remove all the trivial instances in ->slave_alloc or ->slave_configure that just set it to the cmd_per_lun default.

ipr: wait for aborted command responses Fixes a race condition in abort handling that was injected when multiple interrupt support was added. When only a single interrupt is present, the adapter guarantees it will send responses for aborted commands prior to the response for the abort command itself. With multiple interrupts, these responses generally come back on different interrupts, so we need to ensure the abort thread waits until the aborted command is complete so we don't perform a double completion. This race condition was being hit frequently in environments which were triggering command timeouts, which was resulting in a double completion causing a kernel oops.

scsi: ipr: Fix abort path race condition This fixes a race condition in the error handlomg paths of ipr. While a command is outstanding to the adapter, it is placed on a pending queue for the hrrq it is associated with, while holding the HRRQ lock. When a command is completed, it is removed from the pending queue, under HRRQ lock, and placed on a local list. This list is then iterated through without any locks and each command's done function is invoked, inside of which, the command gets returned to the free list while grabbing the HRRQ lock. This fixes two race conditions when commands have been removed from the pending list but have not yet been added to the free list. Both of these changes fix race conditions that could result in returning success from eh_abort_handler and then later calling scsi_done for the same request. The first race condition is in ipr_cancel_op. It looks through each pending queue to see if the command to be aborted is still outstanding or not. Rather than looking on the pending queue, reverse the logic to check to look for commands that are NOT on the free queue. The second race condition can occur when in ipr_wait_for_ops where we are waiting for responses for commands we've aborted.

scsi: ipr: Fix SATA EH hang This patch fixes a hang that can occur in ATA EH with ipr. With ipr's usage of libata, commands should never end up on ap->eh_done_q. The timeout function we use for ipr, even for SATA devices, is scsi_times_out, so ATA_QCFLAG_EH_SCHEDULED never gets set for ipr and EH is driven completely by ipr and SCSI. The SCSI EH thread ends up calling ipr's eh_device_reset_handler, which then calls ata_std_error_handler. This ends up calling ipr_sata_reset, which issues a reset to the device. This should result in all pending commands getting failed back and having ata_qc_complete called for them, which should end up clearing ATA_QCFLAG_FAILED as qc->flags gets zeroed in ata_qc_free. This ensures that when we end up in ata_eh_finish, we don't do anything more with the command. On adapters that only support a single interrupt and when running with two MSI-X vectors or less, the adapter firmware guarantees that responses to all outstanding commands are sent back prior to sending the response to the SATA reset command. On newer adapters supporting multiple HRRQs, however, this can no longer be guaranteed, since the command responses and reset response may be processed on different HRRQs. If ipr returns from ipr_sata_reset before the outstanding command was returned, this sends us down the path of __ata_eh_qc_complete which then moves the associated scsi_cmd from the work_q in scsi_eh_bus_device_reset to ap->eh_done_q, which then will sit there forever and we will be wedged. This patch fixes this up by ensuring that any outstanding commands are flushed before returning from eh_device_reset_handler for a SATA device.

scsi: ipr: Fix SATA EH hang This patch fixes a hang that can occur in ATA EH with ipr. With ipr's usage of libata, commands should never end up on ap->eh_done_q. The timeout function we use for ipr, even for SATA devices, is scsi_times_out, so ATA_QCFLAG_EH_SCHEDULED never gets set for ipr and EH is driven completely by ipr and SCSI. The SCSI EH thread ends up calling ipr's eh_device_reset_handler, which then calls ata_std_error_handler. This ends up calling ipr_sata_reset, which issues a reset to the device. This should result in all pending commands getting failed back and having ata_qc_complete called for them, which should end up clearing ATA_QCFLAG_FAILED as qc->flags gets zeroed in ata_qc_free. This ensures that when we end up in ata_eh_finish, we don't do anything more with the command. On adapters that only support a single interrupt and when running with two MSI-X vectors or less, the adapter firmware guarantees that responses to all outstanding commands are sent back prior to sending the response to the SATA reset command. On newer adapters supporting multiple HRRQs, however, this can no longer be guaranteed, since the command responses and reset response may be processed on different HRRQs. If ipr returns from ipr_sata_reset before the outstanding command was returned, this sends us down the path of __ata_eh_qc_complete which then moves the associated scsi_cmd from the work_q in scsi_eh_bus_device_reset to ap->eh_done_q, which then will sit there forever and we will be wedged. This patch fixes this up by ensuring that any outstanding commands are flushed before returning from eh_device_reset_handler for a SATA device.

scsi: ipr: Fix abort path race condition This fixes a race condition in the error handlomg paths of ipr. While a command is outstanding to the adapter, it is placed on a pending queue for the hrrq it is associated with, while holding the HRRQ lock. When a command is completed, it is removed from the pending queue, under HRRQ lock, and placed on a local list. This list is then iterated through without any locks and each command's done function is invoked, inside of which, the command gets returned to the free list while grabbing the HRRQ lock. This fixes two race conditions when commands have been removed from the pending list but have not yet been added to the free list. Both of these changes fix race conditions that could result in returning success from eh_abort_handler and then later calling scsi_done for the same request. The first race condition is in ipr_cancel_op. It looks through each pending queue to see if the command to be aborted is still outstanding or not. Rather than looking on the pending queue, reverse the logic to check to look for commands that are NOT on the free queue. The second race condition can occur when in ipr_wait_for_ops where we are waiting for responses for commands we've aborted.

scsi: ipr: Fix abort path race condition This fixes a race condition in the error handlomg paths of ipr. While a command is outstanding to the adapter, it is placed on a pending queue for the hrrq it is associated with, while holding the HRRQ lock. When a command is completed, it is removed from the pending queue, under HRRQ lock, and placed on a local list. This list is then iterated through without any locks and each command's done function is invoked, inside of which, the command gets returned to the free list while grabbing the HRRQ lock. This fixes two race conditions when commands have been removed from the pending list but have not yet been added to the free list. Both of these changes fix race conditions that could result in returning success from eh_abort_handler and then later calling scsi_done for the same request. The first race condition is in ipr_cancel_op. It looks through each pending queue to see if the command to be aborted is still outstanding or not. Rather than looking on the pending queue, reverse the logic to check to look for commands that are NOT on the free queue. The second race condition can occur when in ipr_wait_for_ops where we are waiting for responses for commands we've aborted.

libata: make reset related methods proper port operations Currently reset methods are not specified directly in the ata_port_operations table. If a LLD wants to use custom reset methods, it should construct and use a error_handler which uses those reset methods. It's done this way for two reasons. First, the ops table already contained too many methods and adding four more of them would noticeably increase the amount of necessary boilerplate code all over low level drivers. Second, as ->error_handler uses those reset methods, it can get confusing. ie. By overriding ->error_handler, those reset ops can be made useless making layering a bit hazy. Now that ops table uses inheritance, the first problem doesn't exist anymore. The second isn't completely solved but is relieved by providing default values - most drivers can just override what it has implemented and don't have to concern itself about higher level callbacks. In fact, there currently is no driver which actually modifies error handling behavior. Drivers which override ->error_handler just wraps the standard error handler only to prepare the controller for EH. I don't think making ops layering strict has any noticeable benefit. This patch makes ->prereset, ->softreset, ->hardreset, ->postreset and their PMP counterparts propoer ops. Default ops are provided in the base ops tables and drivers are converted to override individual reset methods instead of creating custom error_handler. * ata_std_error_handler() doesn't use sata_std_hardreset() if SCRs aren't accessible. sata_promise doesn't need to use separate error_handlers for PATA and SATA anymore. * softreset is broken for sata_inic162x and sata_sx4. As libata now always prefers hardreset, this doesn't really matter but the ops are forced to NULL using ATA_OP_NULL for documentation purpose. * pata_hpt374 needs to use different prereset for the first and second PCI functions. This used to be done by branching from hpt374_error_handler(). The proper way to do this is to use separate ops and port_info tables for each function. Converted.

When only a single interrupt is present, the adapter guarantees it will send responses for aborted commands prior to the response for the abort command itself.

scsi: ipr: Fix SATA EH hang This patch fixes a hang that can occur in ATA EH with ipr. With ipr's usage of libata, commands should never end up on ap->eh_done_q. The timeout function we use for ipr, even for SATA devices, is scsi_times_out, so ATA_QCFLAG_EH_SCHEDULED never gets set for ipr and EH is driven completely by ipr and SCSI. The SCSI EH thread ends up calling ipr's eh_device_reset_handler, which then calls ata_std_error_handler. This ends up calling ipr_sata_reset, which issues a reset to the device. This should result in all pending commands getting failed back and having ata_qc_complete called for them, which should end up clearing ATA_QCFLAG_FAILED as qc->flags gets zeroed in ata_qc_free. This ensures that when we end up in ata_eh_finish, we don't do anything more with the command. On adapters that only support a single interrupt and when running with two MSI-X vectors or less, the adapter firmware guarantees that responses to all outstanding commands are sent back prior to sending the response to the SATA reset command. On newer adapters supporting multiple HRRQs, however, this can no longer be guaranteed, since the command responses and reset response may be processed on different HRRQs. If ipr returns from ipr_sata_reset before the outstanding command was returned, this sends us down the path of __ata_eh_qc_complete which then moves the associated scsi_cmd from the work_q in scsi_eh_bus_device_reset to ap->eh_done_q, which then will sit there forever and we will be wedged.

[SCSI] ipr: fix eeh recovery for 64-bit adapters In some scenarios, an EEH error can take a long time to be detected, since the driver issues an MMIO read only after a device reset command times out and we try to reset the adapter. This patch adds some code in ipr_cancel_op() to read a hardware register so we detect the error earlier in case the op is being aborted because of a timeout caused by a frozen adapter slot. Another problem in such scenarios is that in __ipr_eh_host_reset() we change the dump state flag from WAIT_FOR_DUMP to GET_DUMP, and the flag is later changed from GET_DUMP to READ_DUMP in ipr_reset_restore_cfg_space(). However, if when __ipr_eh_host_reset() is called by the SCSI error handling the function ipr_reset_restore_cfg_space() has already been called by the PCI EEH code, we end up with the flag in an inconsistent state. This patch also prevents this problem.

scsi: ipr: Fix abort path race condition This fixes a race condition in the error handlomg paths of ipr. While a command is outstanding to the adapter, it is placed on a pending queue for the hrrq it is associated with, while holding the HRRQ lock. When a command is completed, it is removed from the pending queue, under HRRQ lock, and placed on a local list. This list is then iterated through without any locks and each command's done function is invoked, inside of which, the command gets returned to the free list while grabbing the HRRQ lock. This fixes two race conditions when commands have been removed from the pending list but have not yet been added to the free list. Both of these changes fix race conditions that could result in returning success from eh_abort_handler and then later calling scsi_done for the same request. The first race condition is in ipr_cancel_op. It looks through each pending queue to see if the command to be aborted is still outstanding or not. Rather than looking on the pending queue, reverse the logic to check to look for commands that are NOT on the free queue. The second race condition can occur when in ipr_wait_for_ops where we are waiting for responses for commands we've aborted.

ipr: wait for aborted command responses Fixes a race condition in abort handling that was injected when multiple interrupt support was added. When only a single interrupt is present, the adapter guarantees it will send responses for aborted commands prior to the response for the abort command itself. With multiple interrupts, these responses generally come back on different interrupts, so we need to ensure the abort thread waits until the aborted command is complete so we don't perform a double completion. This race condition was being hit frequently in environments which were triggering command timeouts, which was resulting in a double completion causing a kernel oops.

[SCSI] ipr: improve interrupt service routine performance During performance testing on P7 machines it was observed that the interrupt service routine was doing unnecessary MMIO operations. This patch rearranges the logic of the routine and moves some of the code out of the main routine. The result is that there are now fewer MMIO operations in the performance path of the code. As a result of the above change, an existing condition was exposed where the driver could get an "unexpected" hrrq interrupt. The original code would flag the interrupt as unexpected and then reset the adapter. After further analysis it was confirmed that this condition can occasionally occur and that the interrupt can safely be ignored. Additional code in this patch detects this condition, clears the interrupt and allows the driver to continue without resetting the adapter.

/**
* ipr_isr - Interrupt service routine
* @irq: irq number
* @devp: pointer to ioa config struct
*
* Return value:
* IRQ_NONE / IRQ_HANDLED
**/
IRQ: Maintain regs pointer globally rather than passing to IRQ handlers Maintain a per-CPU global "struct pt_regs *" variable which can be used instead of passing regs around manually through all ~1800 interrupt handlers in the Linux kernel. The regs pointer is used in few places, but it potentially costs both stack space and code to pass it around. On the FRV arch, removing the regs parameter from all the genirq function results in a 20% speed up of the IRQ exit path (ie: from leaving timer_interrupt() to leaving do_IRQ()). Where appropriate, an arch may override the generic storage facility and do something different with the variable. On FRV, for instance, the address is maintained in GR28 at all times inside the kernel as part of general exception handling. Having looked over the code, it appears that the parameter may be handed down through up to twenty or so layers of functions. Consider a USB character device attached to a USB hub, attached to a USB controller that posts its interrupts through a cascaded auxiliary interrupt controller. A character device driver may want to pass regs to the sysrq handler through the input layer which adds another few layers of parameter passing. I've build this code with allyesconfig for x86_64 and i386. I've runtested the main part of the code on FRV and i386, though I can't test most of the drivers. I've also done partial conversion for powerpc and MIPS - these at least compile with minimal configurations. This will affect all archs. Mostly the changes should be relatively easy. Take do_IRQ(), store the regs pointer at the beginning, saving the old one: struct pt_regs *old_regs = set_irq_regs(regs); And put the old one back at the end: set_irq_regs(old_regs); Don't pass regs through to generic_handle_irq() or __do_IRQ(). In timer_interrupt(), this sort of change will be necessary: - update_process_times(user_mode(regs)); - profile_tick(CPU_PROFILING, regs); + update_process_times(user_mode(get_irq_regs())); + profile_tick(CPU_PROFILING); I'd like to move update_process_times()'s use of get_irq_regs() into itself, except that i386, alone of the archs, uses something other than user_mode(). Some notes on the interrupt handling in the drivers: (*) input_dev() is now gone entirely. The regs pointer is no longer stored in the input_dev struct. (*) finish_unlinks() in drivers/usb/host/ohci-q.c needs checking. It does something different depending on whether it's been supplied with a regs pointer or not. (*) Various IRQ handler function pointers have been moved to type irq_handler_t.

[SCSI] ipr: improve interrupt service routine performance During performance testing on P7 machines it was observed that the interrupt service routine was doing unnecessary MMIO operations. This patch rearranges the logic of the routine and moves some of the code out of the main routine. The result is that there are now fewer MMIO operations in the performance path of the code. As a result of the above change, an existing condition was exposed where the driver could get an "unexpected" hrrq interrupt. The original code would flag the interrupt as unexpected and then reset the adapter. After further analysis it was confirmed that this condition can occasionally occur and that the interrupt can safely be ignored. Additional code in this patch detects this condition, clears the interrupt and allows the driver to continue without resetting the adapter.

block: remove old blk_iopoll_enabled variable This was a debugging measure to toggle enabled/disabled when testing. But for real production setups, it's not safe to toggle this setting without either reloading drivers of quiescing IO first. Neither of which the toggle enforces. Additionally, it makes drivers deal with the conditional state. Remove it completely. It's up to the driver whether iopoll is enabled or not. Signed-off-by: Jens Axboe <axboe@fb.com>

[SCSI] ipr: Support new device queueing model New ipr adapters support a new device queueing model in the adapter firmware. The queueing model is the NACA queueing model, but it does not mean use of NACA is required. The new model removes some of the adapter firmware queue state that made handling QERR=0 almost impossible. The queueing model on older adapters included the concept of a queue frozen state, which would freeze the response queue in the adapter when a check condition occurred, requiring a a primitive to resume the queue. The new queueing model removes this complexity. Signed-off-by: Brian King <brking@us.ibm.com> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>

scsi: ipr: do not set DID_PASSTHROUGH on CHECK CONDITION On a dual controller setup with multipath enabled, some MEDIUM ERRORs caused both paths to be failed, thus I/O got queued/blocked since the 'queue_if_no_path' feature is enabled by default on IPR controllers. This example disabled 'queue_if_no_path' so the I/O failure is seen at the sg_dd program. Notice that after the sg_dd test-case, both paths are in 'failed' state, and both path/priority groups are in 'enabled' state (not 'active') -- which would block I/O with 'queue_if_no_path'. # sg_dd if=/dev/dm-2 bs=4096 count=1 dio=1 verbose=4 blk_sgio=0 <...> read(unix): count=4096, res=-1 sg_dd: reading, skip=0 : Input/output error <...> # dmesg [...] sd 2:2:16:0: [sds] FAILED Result: hostbyte=DID_OK driverbyte=DRIVER_SENSE [...] sd 2:2:16:0: [sds] Sense Key : Medium Error [current] [...] sd 2:2:16:0: [sds] Add.

The dm-multipath explicitly checks for the MEDIUM ERROR case (and a few others) so not to fail the path (e.g., I/O to other sectors could potentially happen without problems). See dm-mpath.c :: do_end_io_bio() -> noretry_error() !->! fail_path(). The problem trace is: 1) ipr_scsi_done() // SENSE KEY/CHECK CONDITION detected, go to.. 2) ipr_erp_start() // ipr_is_gscsi() and masked_ioasc OK, go to.. 3) ipr_gen_sense() // masked_ioasc is IPR_IOASC_MED_DO_NOT_REALLOC, // so set DID_PASSTHROUGH. 4) scsi_decide_disposition() // check for DID_PASSTHROUGH and return // early on, faking a DID_OK.. *instead* // of reaching scsi_check_sense(). // Had it reached the latter, that would // set host_byte to DID_MEDIUM_ERROR. 5) scsi_finish_command() 6) scsi_io_completion() 7) __scsi_error_from_host_byte() // That would be converted to -ENODATA <...> 8) dm_softirq_done() 9) multipath_end_io() 10) do_end_io() 11) noretry_error() // And that is checked in dm-mpath :: noretry_error() // which would cause fail_path() not to be called.

SCSI host lock push-down Move the mid-layer's ->queuecommand() invocation from being locked with the host lock to being unlocked to facilitate speeding up the critical path for drivers who don't need this lock taken anyway. The patch below presents a simple SCSI host lock push-down as an equivalent transformation. No locking or other behavior should change with this patch. All existing bugs and locking orders are preserved. Additionally, add one parameter to queuecommand, struct Scsi_Host * and remove one parameter from queuecommand, void (*done)(struct scsi_cmnd *) Scsi_Host* is a convenient pointer that most host drivers need anyway, and 'done' is redundant to struct scsi_cmnd->scsi_done. Minimal code disturbance was attempted with this change. Most drivers needed only two one-line modifications for their host lock push-down.

[SCSI] Disable WRITE SAME for RAID and virtual host adapter drivers Some host adapters do not pass commands through to the target disk directly. Instead they provide an emulated target which may or may not accurately report its capabilities. In some cases the physical device characteristics are reported even when the host adapter is processing commands on the device's behalf. This can lead to adapter firmware hangs or excessive I/O errors. This patch disables WRITE SAME for devices connected to host adapters that provide an emulated target. Driver writers can disable WRITE SAME by setting the no_write_same flag in the host adapter template. [jejb: fix up rejections due to eh_deadline patch] Signed-off-by: Martin K.

[libata] kill ata_sg_is_last() Short term, this works around a bug introduced by early sg-chaining work.

libata: eliminate the home grown dma padding in favour of that provided by the block layer ATA requires that all DMA transfers begin and end on word boundaries. Because of this, a large amount of machinery grew up in ide to adjust scatterlists on this basis. However, as of 2.5, the block layer has a dma_alignment variable which ensures both the beginning and length of a DMA transfer are aligned on the dma_alignment boundary. Although the block layer does adjust the beginning of the transfer to ensure this happens, it doesn't actually adjust the length, it merely makes sure that space is allocated for transfers beyond the declared length. The upshot of this is that scatterlists may be padded to any size between the actual length and the length adjusted to the dma_alignment safely knowing that memory is allocated in this region. Right at the moment, SCSI takes the default dma_aligment which is on a 512 byte boundary. Note that this aligment only applies to transfers coming in from user space. However, since all kernel allocations are automatically aligned on a minimum of 32 byte boundaries, it is safe to adjust them in this manner as well. tj: * Adjusting sg after padding is done in block layer. Make libata set queue alignment correctly for ATAPI devices and drop broken sg mangling from ata_sg_setup(). * Use request->raw_data_len for ATAPI transfer chunk size. * Killed qc->raw_nbytes. * Separated out killing qc->n_iter.

libata: replace tf_read with qc_fill_rtf for non-SFF drivers Now that all SFF stuff is separated out of core layer, core layer doesn't call ops->tf_read directly. It gets called only via ops->qc_fill_rtf() for non-SFF drivers. This patch directly implements private ops->qc_fill_rtf() for non-SFF controllers and kill ops->tf_read(). This is much cleaner for non-SFF controllers as some of them have to cache SFF register values in private data structure and report the cached values via ops->tf_read(). Also, ops->tf_read() gets nasty for controllers which don't have clear notion of TF registers when operation is not in progress. As this change makes default ops->qc_fill_rtf unnecessary, move ata_sff_qc_fill_rtf() form ata_base_port_ops to ata_sff_port_ops where it belongs. Signed-off-by: Tejun Heo <htejun@gmail.com>

libata: make reset related methods proper port operations Currently reset methods are not specified directly in the ata_port_operations table. If a LLD wants to use custom reset methods, it should construct and use a error_handler which uses those reset methods. It's done this way for two reasons. First, the ops table already contained too many methods and adding four more of them would noticeably increase the amount of necessary boilerplate code all over low level drivers. Second, as ->error_handler uses those reset methods, it can get confusing. ie. By overriding ->error_handler, those reset ops can be made useless making layering a bit hazy. Now that ops table uses inheritance, the first problem doesn't exist anymore. The second isn't completely solved but is relieved by providing default values - most drivers can just override what it has implemented and don't have to concern itself about higher level callbacks. In fact, there currently is no driver which actually modifies error handling behavior. Drivers which override ->error_handler just wraps the standard error handler only to prepare the controller for EH. I don't think making ops layering strict has any noticeable benefit. This patch makes ->prereset, ->softreset, ->hardreset, ->postreset and their PMP counterparts propoer ops. Default ops are provided in the base ops tables and drivers are converted to override individual reset methods instead of creating custom error_handler. * ata_std_error_handler() doesn't use sata_std_hardreset() if SCRs aren't accessible. sata_promise doesn't need to use separate error_handlers for PATA and SATA anymore. * softreset is broken for sata_inic162x and sata_sx4. As libata now always prefers hardreset, this doesn't really matter but the ops are forced to NULL using ATA_OP_NULL for documentation purpose. * pata_hpt374 needs to use different prereset for the first and second PCI functions. This used to be done by branching from hpt374_error_handler(). The proper way to do this is to use separate ops and port_info tables for each function. Converted.

libata: replace tf_read with qc_fill_rtf for non-SFF drivers Now that all SFF stuff is separated out of core layer, core layer doesn't call ops->tf_read directly. It gets called only via ops->qc_fill_rtf() for non-SFF drivers. This patch directly implements private ops->qc_fill_rtf() for non-SFF controllers and kill ops->tf_read(). This is much cleaner for non-SFF controllers as some of them have to cache SFF register values in private data structure and report the cached values via ops->tf_read(). Also, ops->tf_read() gets nasty for controllers which don't have clear notion of TF registers when operation is not in progress. As this change makes default ops->qc_fill_rtf unnecessary, move ata_sff_qc_fill_rtf() form ata_base_port_ops to ata_sff_port_ops where it belongs. Signed-off-by: Tejun Heo <htejun@gmail.com>

ata: Add a new flag to destinguish sas controller SAS controller has its own tag allocation, which doesn't directly match to ATA tag, so SAS and SATA have different code path for ata tags. Originally we use port->scsi_host (98bd4be1) to destinguish SAS controller, but libsas set ->scsi_host too, so we can't use it for the destinguish, we add a new flag for this purpose. Without this patch, the following oops can happen because scsi-mq uses a host-wide tag map shared among all devices with some integer tag values >= ATA_MAX_QUEUE. These unexpectedly high tag values cause __ata_qc_from_tag() to return NULL, which is then dereferenced in ata_qc_new_init().

[SCSI] ipr: move setting of the allow_restart flag for vsets and disks A problem was found where the call to scsi_add_device() fails intermittently for an adapter. This is caused when __scsi_add_device() returns -ENODEV as a result of not calling scsi_probe_and_add_lun() since the call to scsi_host_scan_allowed() fails. scsi_host_scan_allowed() fails because the adapter state is set to SHOST_RECOVERY instead of SHOST_RUNNING. The state of the adapter is being set to SHOST_RECOVERY by scsi_eh_scmd_add() during error handling. This problem is avoided by moving the setting of the allow_restart flag to later in the device initialization sequence. This prevents further error handling if we get a NOT_READY response from a TUR command by causing scsi_check_sense() to return SUCCESS. Therefore, scsi_eh_scmd_add() will not run and the adapter state will remain as SHOST_RUNNING.

[SCSI] ipr: fix transition to operational for new adapters The method of transitioning to operational for new adapters includes using initialization stages. The current stage is indicated via a register read. The final good stage in the sequence is "operational" but does not necessarily indicate that the driver can proceed. There is another bit that gets set in the adapter->host interrupt register when the adapter has completed enough of its bringup such that it can accept commands. The driver was not checking that bit before proceeding which led to intermittent errors and adapter resets. The fix is to check the "transition to operational" bit in the interrupt register after detecting that the initialization stage is "operational" and only proceed if both are set.

[SCSI] ipr: add endian swap enablement for 64 bit adapters A change in the hardware design of the chip for the new adapters changes the default endianness of MMIO operations. This patch adds a register definition which when written to with a predefined value will change the endianness back to what the driver expects. This patch also fixes two problems found during testing. First, the first reserved field in the ipr_hostrcb64_fabirc_desc structure only reserved one byte. The correct amount to reserve is 2 bytes. Second, the reserved field of the ipr_hostrcb64_error structure only reserved 2 bytes. The correct amount to reserve is 16 bytes.

[SCSI] ipr: fix EEH recovery After commits c82f63e411f1b58427c103bd95af2863b1c96dd1 (PCI: check saved state before restore) and 4b77b0a2ba27d64f58f16d8d4d48d8319dda36ff (PCI: Clear saved_state after the state has been restored) PCI drivers are prevented from restoring the device standard configuration registers twice in a row. These changes introduced a regression on ipr EEH recovery. The ipr device driver saves the PCI state only during the device probe and restores it on ipr_reset_restore_cfg_space() during IOA resets. This behavior is causing the EEH recovery to fail after the second error detected, since the registers are not being restored. One possible solution would be saving the registers after restoring them. The problem with this approach is that while recovering from an EEH error if pci_save_state() results in an EEH error, the adapter/slot will be reset, and end up back in ipr_reset_restore_cfg_space(), but it won't have a valid saved state to restore, so pci_restore_state() will fail. The following patch introduces a workaround for this problem, hacking around the PCI API by setting pdev->state_saved = true before we do the restore. It fixes the EEH regression and prevents that we hit another EEH error during EEH recovery. [jejb: fix is a hack ...

[SCSI] ipr: Use PCI-E reset API for new ipr adapter Use a newly added PCI API to issue a PCI Fundamental reset (warm reset) to a new ipr PCI-E adapter. Typically, the ipr adapter uses the start BIST bit in config space to reset an adapter. Issuing start BIST on this particular adapter results in the PCI-E logic on the card losing sync, which causes PCI-E errors, making the card unusable. The only reset mechanism that exists on this hardware that does not have this problem is PCI Fundamental reset (warm reset).

ipr: Reboot speed improvements Currently when performing a reboot with an ipr adapter, the adapter gets shutdown completely, flushing all write cache, as well as performing a full hardware reset of the card during the shutdown phase of the old kernel. This ensures the adapter is in a fully quiesced state across the reboot. There are scenarios, however, such as when performing kexec, where this full adapter shutdown is not required and not desired, since it can make the reboot process take noticeably longer. This patch adds a module parameter to allow for skipping the full shutdown during reboot. Rather than performing a full adapter shutdown and reset, we simply cancel any outstanding error buffers, place the adapter into a state where it has no memory of any DMA addresses from the old kernel, then disable the device. This significantly speeds up kexec boot, particularly in configurations with multiple ipr adapters.

[SCSI] ipr: Stop reading adapter dump prematurely When the ipr driver decides to dump the adapter, it changes the sdt_state to GET_DUMP, then prepares the adapter so that the dump can be read. However, if the ipr worker thread wakes up for some reason before the driver has put the adapter in a state where it can succesfully dump the adapter, the driver will start dumping the adapter too early, which can potentially trigger a BUG check in the pci config blocking API. Fix this by adding a new sdt_state to differentiate between the ipr driver wanting to dump the adapter in the near future and wanting to dump the adapter now.

When hotplug removing an adapter, we shut it down and go through this same code, but we've seen issues with scsi_unblock_requests running after the adapter's memory has been freed. There is really no need to block/unblock when the adapter is being removed, so this patch skips the block/unblock and will immediately fail any commands that happen to make it to queuecommand while the adapter is being shutdown.

[SCSI] ipr: Driver initialization fix for kexec/kdump When kexec booting a kernel when the previous kernel did not call ipr's shutdown method, the ipr adapter does not get properly initialized, which can result in the ipr adapter completing commands issued by the previous kernel. Fix ipr to detect this scenario by reading the adapter's interrupt mask register and the microprocessor interrupt register. If the interrupt mask register indicates that interrupts are enabled or the reset alert bit is set when the card is probed, this means the card is in an unknown state and we hard reset the card.

Reads to the "async_err_log" attribute will result in a single HCAM buffer being copied to userspace; one can process the next HCAM buffer by writing any string to the same attribute. A new list was added to the ioa_cfg structure to store the HCAM buffers for later reporting. We also send a KOBJ_CHANGE event whenever a new HCAM buffer is made available to userspace.

treewide: kzalloc() -> kcalloc() The kzalloc() function has a 2-factor argument form, kcalloc(). This patch replaces cases of: kzalloc(a * b, gfp) with: kcalloc(a * b, gfp) as well as handling cases of: kzalloc(a * b * c, gfp) with: kzalloc(array3_size(a, b, c), gfp) as it's slightly less ugly than: kzalloc_array(array_size(a, b), c, gfp) This does, however, attempt to ignore constant size factors like: kzalloc(4 * 1024, gfp) though any constants defined via macros get caught up in the conversion.

[SCSI] ipr: update the configuration table code for the next generation chip This patch changes the configuration table structures and related code such that both 32 bit and 64 bit based adapters can work with the driver. This patch also implements the code to generate the virtual bus/id/lun values for devices connected to the new adapters. It also implements support for the new device resource path.

scsi: ipr: Add asynchronous error notification This patch implements functions for pushing HCAM (host controlled asynchronous messages) error buffers to userspace through sysfs attributes. Reads to the "async_err_log" attribute will result in a single HCAM buffer being copied to userspace; one can process the next HCAM buffer by writing any string to the same attribute. A new list was added to the ioa_cfg structure to store the HCAM buffers for later reporting. We also send a KOBJ_CHANGE event whenever a new HCAM buffer is made available to userspace.

treewide: kzalloc() -> kcalloc() The kzalloc() function has a 2-factor argument form, kcalloc(). This patch replaces cases of: kzalloc(a * b, gfp) with: kcalloc(a * b, gfp) as well as handling cases of: kzalloc(a * b * c, gfp) with: kzalloc(array3_size(a, b, c), gfp) as it's slightly less ugly than: kzalloc_array(array_size(a, b), c, gfp) This does, however, attempt to ignore constant size factors like: kzalloc(4 * 1024, gfp) though any constants defined via macros get caught up in the conversion. Any factors with a sizeof() of "unsigned char", "char", and "u8" were dropped, since they're redundant. The Coccinelle script used for this was: // Fix redundant parens around sizeof(). @@ type TYPE; expression THING, E; @@ ( kzalloc( - (sizeof(TYPE)) * E + sizeof(TYPE) * E , ...) | kzalloc( - (sizeof(THING)) * E + sizeof(THING) * E , ...) ) // Drop single-byte sizes and redundant parens. @@ expression COUNT;

scsi: ipr: Add asynchronous error notification This patch implements functions for pushing HCAM (host controlled asynchronous messages) error buffers to userspace through sysfs attributes. Reads to the "async_err_log" attribute will result in a single HCAM buffer being copied to userspace; one can process the next HCAM buffer by writing any string to the same attribute. A new list was added to the ioa_cfg structure to store the HCAM buffers for later reporting. We also send a KOBJ_CHANGE event whenever a new HCAM buffer is made available to userspace.

Then get the adapter reset request again, so driver does scsi_block_requests, this will cause the scsi_add_device get hung until we unblock.

PCI: Change all drivers to use pci_device->revision Instead of all drivers reading pci config space to get the revision ID, they can now use the pci_device->revision member. This exposes some issues where drivers where reading a word or a dword for the revision number, and adding useless error-handling around the read. Some drivers even just read it for no purpose of all. In devices where the revision ID is being copied over and used in what appears to be the equivalent of hotpath, I have left the copy code and the cached copy as not to influence the driver's performance. Compile tested with make all{yes,mod}config on x86_64 and i386.

[SCSI] ipr: Use PCI-E reset API for new ipr adapter Use a newly added PCI API to issue a PCI Fundamental reset (warm reset) to a new ipr PCI-E adapter. Typically, the ipr adapter uses the start BIST bit in config space to reset an adapter. Issuing start BIST on this particular adapter results in the PCI-E logic on the card losing sync, which causes PCI-E errors, making the card unusable. The only reset mechanism that exists on this hardware that does not have this problem is PCI Fundamental reset (warm reset).

scsi: ipr: Use pci_irq_allocate_vectors Switch the ipr driver to use pci_alloc_irq_vectors. We need to two calls to pci_alloc_irq_vectors as ipr only supports multiple MSI-X vectors, but not multiple MSI vectors. Otherwise this cleans up a lot of cruft and allows to use a common request_irq loop for irq types, which happens to only iterate over a single line in the non MSI-X case.

[SCSI] ipr: reorder error handling code to include iounmap The out_msi_disable label should be before cleanup_nomem to additionally benefit from the call to iounmap. Subsequent gotos are adjusted to go to out_msi_disable instead of cleanup_nomem, which now follows it. This is safe because pci_disable_msi does nothing if pci_enable_msi was not called.

scsi: ipr: Add asynchronous error notification This patch implements functions for pushing HCAM (host controlled asynchronous messages) error buffers to userspace through sysfs attributes. Reads to the "async_err_log" attribute will result in a single HCAM buffer being copied to userspace; one can process the next HCAM buffer by writing any string to the same attribute. A new list was added to the ioa_cfg structure to store the HCAM buffers for later reporting. We also send a KOBJ_CHANGE event whenever a new HCAM buffer is made available to userspace.

ipr: Reboot speed improvements Currently when performing a reboot with an ipr adapter, the adapter gets shutdown completely, flushing all write cache, as well as performing a full hardware reset of the card during the shutdown phase of the old kernel. This ensures the adapter is in a fully quiesced state across the reboot. There are scenarios, however, such as when performing kexec, where this full adapter shutdown is not required and not desired, since it can make the reboot process take noticeably longer. This patch adds a module parameter to allow for skipping the full shutdown during reboot. Rather than performing a full adapter shutdown and reset, we simply cancel any outstanding error buffers, place the adapter into a state where it has no memory of any DMA addresses from the old kernel, then disable the device. This significantly speeds up kexec boot, particularly in configurations with multiple ipr adapters.

We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it.

[SCSI] ipr: Use PCI-E reset API for new ipr adapter Use a newly added PCI API to issue a PCI Fundamental reset (warm reset) to a new ipr PCI-E adapter. Typically, the ipr adapter uses the start BIST bit in config space to reset an adapter. Issuing start BIST on this particular adapter results in the PCI-E logic on the card losing sync, which causes PCI-E errors, making the card unusable. The only reset mechanism that exists on this hardware that does not have this problem is PCI Fundamental reset (warm reset).

ipr: Reboot speed improvements Currently when performing a reboot with an ipr adapter, the adapter gets shutdown completely, flushing all write cache, as well as performing a full hardware reset of the card during the shutdown phase of the old kernel. This ensures the adapter is in a fully quiesced state across the reboot. There are scenarios, however, such as when performing kexec, where this full adapter shutdown is not required and not desired, since it can make the reboot process take noticeably longer. This patch adds a module parameter to allow for skipping the full shutdown during reboot. Rather than performing a full adapter shutdown and reset, we simply cancel any outstanding error buffers, place the adapter into a state where it has no memory of any DMA addresses from the old kernel, then disable the device. This significantly speeds up kexec boot, particularly in configurations with multiple ipr adapters.
