* scsi: message: fusion: Use GFP_KERNELJulia Lawall2022-02-111-1/+1
| | | | | | | | | | | Pci_driver probe functions aren't called with locks held and thus don't need GFP_ATOMIC. Use GFP_KERNEL instead. Problem found with Coccinelle.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In [1], Christoph Hellwig has proposed to remove the wrappers in include/linux/pci-dma-compat.h. Some reasons why this API should be removed have been given by Julia Lawall in [2]. When memory is allocated in kbuf_alloc_2_sgl() GFP_KERNEL can be used because this function already uses the GFP_USER flag for some memory allocation and not spin_lock is taken in the between. When memory is allocated in mptctl_do_mpt_command() GFP_KERNEL can be used because this function already uses copy_from_user() and this function can sleep. When memory is allocated in mptctl_hp_hostinfo() GFP_KERNEL can be used because this function already uses mpt_config() and this function has an explicit might_sleep(). When memory is allocated in mptctl_hp_targetinfo() GFP_KERNEL can be used because this function already uses mpt_config() and this function has an explicit might_sleep().

Aside of that in_interrupt() is deprecated as it does not provide what the name suggests. It covers more than hard/soft interrupt servicing context and is semantically ill defined. Looking closer there are a few problems with the current construct: - It could be invoked from an interrupt handler / non-blocking context because cancel_delayed_work() has no such restriction. Also, mptsas_free_fw_event() has no such restriction. - The list is accessed unlocked. It may dequeue a valid work-item but at the time of invoking cancel_delayed_work() the memory may be released or reused because the worker has already run. mptsas_cleanup_fw_event_q() is invoked via mptsas_shutdown() which is always invoked from preemtible context on device shutdown. It is also invoked via mptsas_ioc_reset(, MPT_IOC_POST_RESET) which is a MptResetHandlers callback. The only caller here are mpt_SoftResetHandler(), mpt_HardResetHandler() and mpt_Soft_Hard_ResetHandler(). All these functions have a `sleepFlag' argument and each caller uses caller uses `CAN_SLEEP' here and according to current documentation: | @sleepFlag: Indicates if sleep or schedule must be called So it is safe to sleep. Add mptsas_hotplug_event::users member. Initialize it to one by default so mptsas_free_fw_event() will free the memory. mptsas_cleanup_fw_event_q() will increment its value for items it dequeues and then it may keep a pointer after dropping the lock. Invoke cancel_delayed_work_sync() to cancel the work item and wait if the worker is currently busy. Free the memory afterwards since it owns the last reference to it.

* scsi: mptfusion: Don't use GFP_ATOMIC for larger DMA allocationsChristoph Hellwig2020-06-261-21/+20
| | | | | | | | | | | | | | | | The mpt fusion driver still uses the legacy PCI DMA API which hardcodes atomic allocations. This caused the driver to fail to load on some powerpc VMs with incoherent DMA and small memory sizes. Switch to use the modern DMA API and sleeping allocations for large allocations instead. This is not a full cleanup of the PCI DMA API usage yet, but just enough to fix the regression caused by reducing the default atomic pool size.

That may lead to a read from unallocated area, sometimes from another (unallocated) page. To fix this, limit the read size to MPT_SENSE_BUFFER_ALLOC.

* scsi: message: fusion: Replace zero-length array with flexible-array memberGustavo A. R. Silva2020-03-261-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current codebase makes use of the zero-length array language extension to the C90 standard, but the preferred mechanism to declare variable-length types such as these ones is a flexible array member[1][2], introduced in C99: struct foo { int stuff; struct boo array[]; }; By making use of the mechanism above, we will get a compiler warning in case the flexible array does not occur last in the structure, which will help us prevent some kind of undefined behavior bugs from being inadvertently introduced[3] to the codebase from now on. Also, notice that, dynamic memory allocations won't be affected by this change: "Flexible array members have incomplete type, and so the sizeof operator may not be applied. As a quirk of the original implementation of zero-length arrays, sizeof evaluates to zero."[1] This issue was found with the help of Coccinelle.

The problem that could cause is: drivers/message/fusion/mptctl.c 674 /* All of these commands require an interrupt or 675 * are unknown/illegal. 676 */ 677 if ((ret = mptctl_syscall_down(iocp, nonblock)) != 0) ^^^^ We take this lock. 678 return ret; 679 680 if (cmd == MPTFWDOWNLOAD) 681 ret = mptctl_fw_download(arg); ^^^ Then the user memory changes and we look up "iocp" again but a different one so now we are holding the incorrect lock and have a race condition. 682 else if (cmd == MPTCOMMAND) 683 ret = mptctl_mpt_command(arg); The security impact of this bug is not as bad as it could have been because these operations are all privileged and root already has enormous destructive power. But it's still worth fixing. This patch passes the "iocp" pointer to the functions to avoid the second lookup. That deletes 100 lines of code from the driver so it's a nice clean up as well.

Plus number of minor changes, spelling fixes and other trivia. The big merge conflict this time around is the SPDX licence tags. Following discussion on linux-next, we believe our version to be more accurate than the one in the tree, so the resolution is to take our version for all the SPDX conflicts" Note on the SPDX license tag conversion conflicts: the SCSI tree had done its own SPDX conversion, which in some cases conflicted with the treewide ones done by Thomas & co. In almost all cases, the conflicts were purely syntactic: the SCSI tree used the old-style SPDX tags ("GPL-2.0" and "GPL-2.0+") while the treewide conversion had used the new-style ones ("GPL-2.0-only" and "GPL-2.0-or-later"). In these cases I picked the new-style one. In a few cases, the SPDX conversion was actually different, though. As explained by James above, and in more detail in a pre-pull-request thread: "The other problem is actually substantive: In the libsas code Luben Tuikov originally specified gpl 2.0 only by dint of stating: * This file is licensed under GPLv2. In all the libsas files, but then muddied the water by quoting GPLv2 verbatim (which includes the or later than language). So for these files Christoph did the conversion to v2 only SPDX tags and Thomas converted to v2 or later tags" So in those cases, where the spdx tag substantially mattered, I took the SCSI tree conversion of it, but then also took the opportunity to turn the old-style "GPL-2.0" into a new-style "GPL-2.0-only" tag. Similarly, when there were whitespace differences or other differences to the comments around the copyright notices, I took the version from the SCSI tree as being the more specific conversion. Finally, in the spdx conversions that had no conflicts (because the treewide ones hadn't been done for those files), I just took the SCSI tree version as-is, even if it was old-style. The old-style conversions are perfectly valid, even if the "-only" and "-or-later" versions are perhaps more descriptive. * tag 'scsi-misc' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi: (185 commits) scsi: qla2xxx: move IO flush to the front of NVME rport unregistration scsi: qla2xxx: Fix NVME cmd and LS cmd timeout race condition scsi: qla2xxx: on session delete, return nvme cmd scsi: qla2xxx: Fix kernel crash after disconnecting NVMe devices scsi: megaraid_sas: Update driver version to 07.710.06.00-rc1 scsi: megaraid_sas: Introduce various Aero performance modes scsi: megaraid_sas: Use high IOPS queues based on IO workload scsi: megaraid_sas: Set affinity for high IOPS reply queues scsi: megaraid_sas: Enable coalescing for high IOPS queues scsi: megaraid_sas: Add support for High IOPS queues scsi: megaraid_sas: Add support for MPI toolbox commands scsi: megaraid_sas: Offload Aero RAID5/6 division calculations to driver scsi: megaraid_sas: RAID1 PCI bandwidth limit algorithm is applicable for only Ventura scsi: megaraid_sas: megaraid_sas: Add check for count returned by HOST_DEVICE_LIST DCMD scsi: megaraid_sas: Handle sequence JBOD map failure at driver level scsi: megaraid_sas: Don't send FPIO to RL Bypass queue scsi: megaraid_sas: In probe context, retry IOC INIT once if firmware is in fault scsi: megaraid_sas: Release Mutex lock before OCR in case of DCMD timeout scsi: megaraid_sas: Call disable_irq from process IRQ poll scsi: megaraid_sas: Remove few debug counters from IO path ...
