Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. 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] aacraid: Add new code for PMC-Sierra's SRC based controller family Added new hardware device 0x28b interface for PMC-Sierra's SRC based controller family. - new src.c file for 0x28b specific functions - new XPORT header required - sync. command interface: doorbell bits shifted (SRC_ODR_SHIFT, SRC_IDR_SHIFT) - async. Interface: different inbound queue handling, no outbound I2O queue available, using doorbell ("PmDoorBellResponseSent") and response buffer on the host ("host_rrq") for status - changed AIF (adapter initiated FIBs) interface: "DoorBellAifPending" bit to inform about pending AIF, "AifRequest" command to read AIF, "NoMoreAifDataAvailable" to mark the end of the AIFs Signed-off-by: Mahesh Rajashekhara <aacraid@pmc-sierra.com> Signed-off-by: James Bottomley <James.Bottomley@suse.de>

[SCSI] aacraid: controller hangs if kernel uses non-default ASPM policy Aacraid controller can hang on some nodes if kernel uses non-default (powersave) ASPM policy. Controller hangs shortly after successful load and hardware detection. Scsi error handler detects this hang and tries to restart hardware but it does not help. Initially it was noticed on RHEL6-based openVZ kernel after backporting aacraid driver from mainline (RHEL6 kernel with original driver works well) http://bugzilla.openvz.org/show_bug.cgi?id=2043 This issue happens because default ASPM policy was changed in Red Hat kernels. Therefore guys from Red Hat have noticed this problem long time ago: on Fedora 12 https://bugzilla.redhat.com/show_bug.cgi?id=540478 on Fedora 14 https://bugzilla.redhat.com/show_bug.cgi?id=679385 In RHEL6 kernel this issue was fixed, ASPM was disabled in aacraid driver. In kernel changelog I've found that seems it was done by Matthew Garrett: - [scsi] aacraid: Disable ASPM by default (Matthew Garrett) [599735] However seems this patch was not submitted to mainline. I've reproduced this issue on vanilla 3.1.0 kernel booted with "pcie_aspm.policy=powersave" option, So I believe it makes sense to do it now.

scsi: autoconvert trivial BKL users to private mutex All these files use the big kernel lock in a trivial way to serialize their private file operations, typically resulting from an earlier semi-automatic pushdown from VFS. None of these drivers appears to want to lock against other code, and they all use the BKL as the top-level lock in their file operations, meaning that there is no lock-order inversion problem. Consequently, we can remove the BKL completely, replacing it with a per-file mutex in every case. Using a scripted approach means we can avoid typos. file=$1 name=$2 if grep -q lock_kernel ${file} ; then if grep -q 'include.*linux.mutex.h' ${file} ; then sed -i '/include.*<linux\/smp_lock.h>/d' ${file} else sed -i 's/include.*<linux\/smp_lock.h>.*$/include <linux\/mutex.h>/g' ${file} fi sed -i ${file} \ -e "/^#include.*linux.mutex.h/,$ { 1,/^\(static\|int\|long\)/ { /^\(static\|int\|long\)/istatic DEFINE_MUTEX(${name}_mutex); } }" \ -e "s/\(un\)*lock_kernel\>[ ]*()/mutex_\1lock(\&${name}_mutex)/g" \ -e '/[ ]*cycle_kernel_lock();/d' else sed -i -e '/include.*\<smp_lock.h\>/d' ${file} \ -e '/cycle_kernel_lock()/d' fi Signed-off-by: Arnd Bergmann <arnd@arndb.de> Cc: linux-scsi@vger.kernel.org Cc: "James E.J.

[SCSI] aacraid: fix driver failure with Dell PowerEdge Expandable RAID Controller 3/Di As reported in http://bugzilla.kernel.org/show_bug.cgi?id=3D9133 it was discovered that the PERC line of controllers lacked a key 64 bit ScatterGather capable SCSI pass-through function. The adapters are still capable of 64 bit ScatterGather I/O commands, but these two can not be mixed. This problem was exacerbated by the introduction of the SCSI Generic access to the DASD physical devices. The fix for users before this patch is applied is aacraid.dacmode=3D0 on the kernel command line to disable 64 bit I/O. The enclosed patch introduces a new adapter quirk and tries to limp along by enabling pass-through in situations where memory is 32 bit addressable on 64 bit machines, or disable the pass-through functions altogether. I expect that the check for 32 bit addressable memory to be controversial in that it can be incorrect in non-Dell non-Intel systems that PERC would never be installed under, the alternative is to disable pass-through in all cases which could be reported as another regression. Pass-through is used for SCSI Generic access to the physical devices, or for the management applications to properly function. In systems where this patch has disabled pass-through because it is unsupportable in combination with I/O performance, the user can choose to enable pass-through by turning off dacmode (aacraid.dacmode=3D0) or limiting the discovered kernel memory (mem=3D4G) with an associated loss in runtime performance. If we chose instead to turn off 64 bit dacmode for the adapters with this quirk, then this would be reported as another regression.

[SCSI] aacraid: fix driver failure with Dell PowerEdge Expandable RAID Controller 3/Di As reported in http://bugzilla.kernel.org/show_bug.cgi?id=3D9133 it was discovered that the PERC line of controllers lacked a key 64 bit ScatterGather capable SCSI pass-through function. The adapters are still capable of 64 bit ScatterGather I/O commands, but these two can not be mixed. This problem was exacerbated by the introduction of the SCSI Generic access to the DASD physical devices. The fix for users before this patch is applied is aacraid.dacmode=3D0 on the kernel command line to disable 64 bit I/O. The enclosed patch introduces a new adapter quirk and tries to limp along by enabling pass-through in situations where memory is 32 bit addressable on 64 bit machines, or disable the pass-through functions altogether. I expect that the check for 32 bit addressable memory to be controversial in that it can be incorrect in non-Dell non-Intel systems that PERC would never be installed under, the alternative is to disable pass-through in all cases which could be reported as another regression. Pass-through is used for SCSI Generic access to the physical devices, or for the management applications to properly function. In systems where this patch has disabled pass-through because it is unsupportable in combination with I/O performance, the user can choose to enable pass-through by turning off dacmode (aacraid.dacmode=3D0) or limiting the discovered kernel memory (mem=3D4G) with an associated loss in runtime performance. If we chose instead to turn off 64 bit dacmode for the adapters with this quirk, then this would be reported as another regression.

[SCSI] aacraid: add Voodoo Lite class of cards. The cards being added are supported in a limited sense already through family matching, but we needed to add some functionality to the driver to expose selectively the physical drives. These Physical drives are specifically marked to not be part of any array and thus are declared JBODs (Just a Bunch Of Drives) for generic SCSI access. We report that this is the second patch in a set of two, but merely depends on the stand-alone functionality of the first patch which adds in that case the ability to report a driver feature flag via sysfs. We leverage that functionality by reporting that this driver now supports this new JBOD feature for the controller so that the array management applications may react accordingly and guide the user as they manage the controller.

[SCSI] aacraid: improve queue balancing The adapter queue is divided up equally to all the arrays to prevent command starvation to any individual array. On the other hand, physical targets are only granted a queue depth of one each. The code prior to this patch used to deal with the incremental discovery of targets, but the driver knows how many arrays are present prior to the scan so this knowledge is used to generate a better estimate for the queue depth. Remove the capability of 'physical=0' from preventing access to the class of adapters that have the RAID/SCSI mode of operation since none of the physicals on the SCSI channel are candidates ever for an array. As always, the user can override this default queue depth policy by making the appropriate adjustments utilizing sysfs.

aacraid: SCSI blk tag support The method to allocate and free FIB's in the present code utilizes spinlocks. Multiple IO's have to wait on the spinlock to acquire or free fibs creating a performance bottleneck. An alternative solution would be to use block layer tags to keep track of the fibs allocated and freed. To this end aac_fib_alloc_tag was created to utilize the blk layer tags to plug into the Fib pool.These functions are used exclusively in the IO path. 8 fibs are reserved for the use of AIF management software and utilize the previous spinlock based implementations.

My research into how GCC and Clang are handling this at a low level didn't prove fruitful. However, looking at the rest of the kernel tree, all ioctls use an 'unsigned int' for the cmd parameter, which will fit all of the _IOC values in the scsi/ata subsystems. Make that change because none of the ioctls expect a negative value for any command, it brings the ioctls inline with the reset of the kernel, and it removes ambiguity, which is never good when dealing with compilers.

[SCSI] aacraid: fix security weakness Actually there are several but one is trivially fixed 1. FSACTL_GET_NEXT_ADAPTER_FIB ioctl does not lock dev->fib_list but needs to 2. Ditto for FSACTL_CLOSE_GET_ADAPTER_FIB 3. It is possible to construct an attack via the SRB ioctls where the user obtains assorted elevated privileges. Various approaches are possible, the trivial ones being things like writing to the raw media via scsi commands and the swap image of other executing programs with higher privileges. So the ioctls should be CAP_SYS_RAWIO - at least all the FIB manipulating ones. This is a bandaid fix for #3 but probably the ioctls should grow their own capable checks. The other two bugs need someone competent in that driver to fix them.

[SCSI] aacraid: Improved error handling Received from Mark Salyzyn, This set of fixes improve error handling stability of the driver. A popular manifestation of the problems is an NULL pointer reference in the interrupt handler when referencing portions of the scsi command context, or in the scsi_done handling when an offlined device is referenced. The aacraid driver currently does not get notification of orphaned command completions due to devices going offline. The driver also fails to handle the commands that are finished by the error handler, and thus can complete again later at the hands of the adapter causing situations of completion of an invalid scsi command context. Test Unit Ready calls abort assuming that the abort was successful, but are not, and thus when the interrupt from the adapter occurs, they reference invalid command contexts. We add in a TIMED_OUT flag to inform the aacraid FIB context that the interrupt service should merely release the driver resources and not complete the command up. We take advantage of this with the abort handler as well for select abortable commands. And we detect and react if a command that can not be aborted is currently still outstanding to the controller when reissued by the retry mechanism.

The cmd->SCp.phase is set in the aac_valid_context routine, then set again to the same value following it's return. The cmd->scsi_done is set twice in the aac_queuecommand routine. Free up the scsidev FILO in aac_probe_container as it is not needed further down the function in any case. Improve the efficiency of the abort handler kernel print parameters.

In experiments in the lab we managed to trigger an Adapter firmware panic (BlinkLED) coincidentally while several pass-through ioctl command from the management software were outstanding on a bug only present on a class of RAID Adapters that require a hardware reset rather than a commanded reset. The net result was an attempt to time out the management software command as if it came from the SCSI layer resulting in an OS panic. Adapters that use commanded reset, management commands are returned failed by the Adapter correctly. The adapter firmware panic that resulted in this condition was also resolved, and there were no adapters in the field with this specific firmware bug so we do not expect any field reports. This is a rare or unlikely corner condition, and no reports have ever been forwarded from the field.

[SCSI] aacraid: Improved error handling Received from Mark Salyzyn, This set of fixes improve error handling stability of the driver. A popular manifestation of the problems is an NULL pointer reference in the interrupt handler when referencing portions of the scsi command context, or in the scsi_done handling when an offlined device is referenced. The aacraid driver currently does not get notification of orphaned command completions due to devices going offline. The driver also fails to handle the commands that are finished by the error handler, and thus can complete again later at the hands of the adapter causing situations of completion of an invalid scsi command context. Test Unit Ready calls abort assuming that the abort was successful, but are not, and thus when the interrupt from the adapter occurs, they reference invalid command contexts. We add in a TIMED_OUT flag to inform the aacraid FIB context that the interrupt service should merely release the driver resources and not complete the command up. We take advantage of this with the abort handler as well for select abortable commands. And we detect and react if a command that can not be aborted is currently still outstanding to the controller when reissued by the retry mechanism.

[SCSI] aacraid: Improved error handling Received from Mark Salyzyn, This set of fixes improve error handling stability of the driver. A popular manifestation of the problems is an NULL pointer reference in the interrupt handler when referencing portions of the scsi command context, or in the scsi_done handling when an offlined device is referenced. The aacraid driver currently does not get notification of orphaned command completions due to devices going offline. The driver also fails to handle the commands that are finished by the error handler, and thus can complete again later at the hands of the adapter causing situations of completion of an invalid scsi command context. Test Unit Ready calls abort assuming that the abort was successful, but are not, and thus when the interrupt from the adapter occurs, they reference invalid command contexts. We add in a TIMED_OUT flag to inform the aacraid FIB context that the interrupt service should merely release the driver resources and not complete the command up. We take advantage of this with the abort handler as well for select abortable commands. And we detect and react if a command that can not be aborted is currently still outstanding to the controller when reissued by the retry mechanism.

My research into how GCC and Clang are handling this at a low level didn't prove fruitful. However, looking at the rest of the kernel tree, all ioctls use an 'unsigned int' for the cmd parameter, which will fit all of the _IOC values in the scsi/ata subsystems. Make that change because none of the ioctls expect a negative value for any command, it brings the ioctls inline with the reset of the kernel, and it removes ambiguity, which is never good when dealing with compilers.

[SCSI] aacraid: fix security weakness Actually there are several but one is trivially fixed 1. FSACTL_GET_NEXT_ADAPTER_FIB ioctl does not lock dev->fib_list but needs to 2. Ditto for FSACTL_CLOSE_GET_ADAPTER_FIB 3. It is possible to construct an attack via the SRB ioctls where the user obtains assorted elevated privileges. Various approaches are possible, the trivial ones being things like writing to the raw media via scsi commands and the swap image of other executing programs with higher privileges. So the ioctls should be CAP_SYS_RAWIO - at least all the FIB manipulating ones. This is a bandaid fix for #3 but probably the ioctls should grow their own capable checks. The other two bugs need someone competent in that driver to fix them.

[SCSI] aacraid: add Voodoo Lite class of cards. The cards being added are supported in a limited sense already through family matching, but we needed to add some functionality to the driver to expose selectively the physical drives. These Physical drives are specifically marked to not be part of any array and thus are declared JBODs (Just a Bunch Of Drives) for generic SCSI access. We report that this is the second patch in a set of two, but merely depends on the stand-alone functionality of the first patch which adds in that case the ability to report a driver feature flag via sysfs. We leverage that functionality by reporting that this driver now supports this new JBOD feature for the controller so that the array management applications may react accordingly and guide the user as they manage the controller.

llseek: automatically add .llseek fop All file_operations should get a .llseek operation so we can make nonseekable_open the default for future file operations without a .llseek pointer. The three cases that we can automatically detect are no_llseek, seq_lseek and default_llseek. For cases where we can we can automatically prove that the file offset is always ignored, we use noop_llseek, which maintains the current behavior of not returning an error from a seek. New drivers should normally not use noop_llseek but instead use no_llseek and call nonseekable_open at open time. Existing drivers can be converted to do the same when the maintainer knows for certain that no user code relies on calling seek on the device file. The generated code is often incorrectly indented and right now contains comments that clarify for each added line why a specific variant was chosen. In the version that gets submitted upstream, the comments will be gone and I will manually fix the indentation, because there does not seem to be a way to do that using coccinelle. Some amount of new code is currently sitting in linux-next that should get the same modifications, which I will do at the end of the merge window. Many thanks to Julia Lawall for helping me learn to write a semantic patch that does all this. ===== begin semantic patch ===== // This adds an llseek= method to all file operations, // as a preparation for making no_llseek the default. // // The rules are // - use no_llseek explicitly if we do nonseekable_open // - use seq_lseek for sequential files // - use default_llseek if we know we access f_pos // - use noop_llseek if we know we don't access f_pos, // but we still want to allow users to call lseek // @ open1 exists @ identifier nested_open; @@ nested_open(...) { <+... nonseekable_open(...) ...+> } @ open exists@ identifier open_f; identifier i, f; identifier open1.nested_open; @@ int open_f(struct inode *i, struct file *f) { <+...

[SCSI] aacraid: Improved error handling Received from Mark Salyzyn, This set of fixes improve error handling stability of the driver. A popular manifestation of the problems is an NULL pointer reference in the interrupt handler when referencing portions of the scsi command context, or in the scsi_done handling when an offlined device is referenced. The aacraid driver currently does not get notification of orphaned command completions due to devices going offline. The driver also fails to handle the commands that are finished by the error handler, and thus can complete again later at the hands of the adapter causing situations of completion of an invalid scsi command context. Test Unit Ready calls abort assuming that the abort was successful, but are not, and thus when the interrupt from the adapter occurs, they reference invalid command contexts. We add in a TIMED_OUT flag to inform the aacraid FIB context that the interrupt service should merely release the driver resources and not complete the command up. We take advantage of this with the abort handler as well for select abortable commands. And we detect and react if a command that can not be aborted is currently still outstanding to the controller when reissued by the retry mechanism.

[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.

[SCSI] aacraid: fix shutdown handler to also disable interrupts. Moves quiesce, thread and interrupt shutdown into aacraid drivers' .shutdown handler. This fix to the aac_shutdown handler will remove the superfluous reset of the adapter during a (clean) kexec. This fix may mitigate the active investigation 'kexec and aacraid broken' but it is unlikely to affect the root cause (issue likely present in both kexec and kdump). This patch reduces the chance the problem will occur with a kexec. The fix for root cause is currently expected to be the minimum value check to the aacraid.startup_timeout driver variable after an adapter reset within aacraid_commit_reset.patch submitted on 05/22/2007 and awaiting testing by Yinghai to confirm.

[SCSI] aacraid: controller hangs if kernel uses non-default ASPM policy Aacraid controller can hang on some nodes if kernel uses non-default (powersave) ASPM policy. Controller hangs shortly after successful load and hardware detection. Scsi error handler detects this hang and tries to restart hardware but it does not help. Initially it was noticed on RHEL6-based openVZ kernel after backporting aacraid driver from mainline (RHEL6 kernel with original driver works well) http://bugzilla.openvz.org/show_bug.cgi?id=2043 This issue happens because default ASPM policy was changed in Red Hat kernels. Therefore guys from Red Hat have noticed this problem long time ago: on Fedora 12 https://bugzilla.redhat.com/show_bug.cgi?id=540478 on Fedora 14 https://bugzilla.redhat.com/show_bug.cgi?id=679385 In RHEL6 kernel this issue was fixed, ASPM was disabled in aacraid driver. In kernel changelog I've found that seems it was done by Matthew Garrett: - [scsi] aacraid: Disable ASPM by default (Matthew Garrett) [599735] However seems this patch was not submitted to mainline. I've reproduced this issue on vanilla 3.1.0 kernel booted with "pcie_aspm.policy=powersave" option, So I believe it makes sense to do it now.

scsi: aacraid: Perform initialization reset only once Currently the driver accepts two ways of requesting an initialization reset on the adapter: by passing aac_reset_devices module parameter, or the generic kernel parameter reset_devices. It's working as intended...but if we end up reaching a scsi hang and the scsi EH mechanism takes place, aacraid performs resets as part of the scsi error recovery procedure. These EH routines might reinitialize the device, and if we have provided some of the reset parameters in the kernel command-line, we again perform an "initialization" reset. So, to avoid this duplication of resets in case of scsi EH path, this patch adds a field to aac_dev struct to keep per-adapter track of the init reset request - once it's done, we set it to false and don't proactively reset anymore in case of reinitializations.

treewide: kzalloc() -> kcalloc() The kzalloc() function has a 2-factor argument form, kcalloc().

However, pci_set_drvdata(pdev, shost) is done in aac_probe_one() far after bailing out with error from calling the init function ((*aac_drivers[index].init)(aac)), and when the init function fails, no error is returned from aac_probe_one() so PCI layer assumes there is driver attached, and tries to shut it down later. Fix it by returning error from aac_probe_one() when card-specific init function fails. This fixes reboot on my HP NetRAID-4M with dead battery.

[SCSI] aacraid: add Voodoo Lite class of cards. The cards being added are supported in a limited sense already through family matching, but we needed to add some functionality to the driver to expose selectively the physical drives. These Physical drives are specifically marked to not be part of any array and thus are declared JBODs (Just a Bunch Of Drives) for generic SCSI access. We report that this is the second patch in a set of two, but merely depends on the stand-alone functionality of the first patch which adds in that case the ability to report a driver feature flag via sysfs. We leverage that functionality by reporting that this driver now supports this new JBOD feature for the controller so that the array management applications may react accordingly and guide the user as they manage the controller.

This fix to the aac_shutdown handler will remove the superfluous reset of the adapter during a (clean) kexec. This fix may mitigate the active investigation 'kexec and aacraid broken' but it is unlikely to affect the root cause (issue likely present in both kexec and kdump). This patch reduces the chance the problem will occur with a kexec. The fix for root cause is currently expected to be the minimum value check to the aacraid.startup_timeout driver variable after an adapter reset within aacraid_commit_reset.patch submitted on 05/22/2007 and awaiting testing by Yinghai to confirm.

[SCSI] aacraid: fix shutdown handler to also disable interrupts. Moves quiesce, thread and interrupt shutdown into aacraid drivers' .shutdown handler. This fix to the aac_shutdown handler will remove the superfluous reset of the adapter during a (clean) kexec. This fix may mitigate the active investigation 'kexec and aacraid broken' but it is unlikely to affect the root cause (issue likely present in both kexec and kdump). This patch reduces the chance the problem will occur with a kexec. The fix for root cause is currently expected to be the minimum value check to the aacraid.startup_timeout driver variable after an adapter reset within aacraid_commit_reset.patch submitted on 05/22/2007 and awaiting testing by Yinghai to confirm.

Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. 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. Let it rip!
