Commit 406f42fa ("net-next: When a bond have a massive amount of VLANs...") introduced a rbtree for faster Ethernet address look up. To maintain netdev->dev_addr in this tree we need to make all the writes to it go through appropriate helpers. Signed-off-by:

The wrappers in include/linux/pci-dma-compat.h should go away. The patch has been generated with the coccinelle script below and has been hand modified to replace GFP_ with a correct flag. It has been compile tested. When memory is allocated in 'mptfc_GetFcDevPage0()' GFP_KERNEL can be used because it is already used in this function and no lock is acquired in the between. When memory is allocated in 'mptfc_GetFcPortPage0()' and 'mptfc_GetFcPortPage1()' GFP_KERNEL can be used because they already call 'mpt_config()' which has an explicit 'might_sleep()'. While at it, also remove some useless casting. @@ @@ - PCI_DMA_BIDIRECTIONAL + DMA_BIDIRECTIONAL @@ @@ - PCI_DMA_TODEVICE + DMA_TO_DEVICE @@ @@ - PCI_DMA_FROMDEVICE + DMA_FROM_DEVICE @@ @@ - PCI_DMA_NONE + DMA_NONE @@ expression e1, e2, e3; @@ - pci_alloc_consistent(e1, e2, e3) + dma_alloc_coherent(&e1->dev, e2, e3, GFP_) @@ expression e1, e2, e3; @@ - pci_zalloc_consistent(e1, e2, e3) + dma_alloc_coherent(&e1->dev, e2, e3, GFP_) @@ expression e1, e2, e3, e4; @@ - pci_free_consistent(e1, e2, e3, e4) + dma_free_coherent(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4; @@ - pci_map_single(e1, e2, e3, e4) + dma_map_single(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4; @@ - pci_unmap_single(e1, e2, e3, e4) + dma_unmap_single(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4, e5; @@ - pci_map_page(e1, e2, e3, e4, e5) + dma_map_page(&e1->dev, e2, e3, e4, e5) @@ expression e1, e2, e3, e4; @@ - pci_unmap_page(e1, e2, e3, e4) + dma_unmap_page(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4; @@ - pci_map_sg(e1, e2, e3, e4) + dma_map_sg(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4; @@ - pci_unmap_sg(e1, e2, e3, e4) + dma_unmap_sg(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4; @@ - pci_dma_sync_single_for_cpu(e1, e2, e3, e4) + dma_sync_single_for_cpu(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4; @@ - pci_dma_sync_single_for_device(e1, e2, e3, e4) + dma_sync_single_for_device(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4; @@ - pci_dma_sync_sg_for_cpu(e1, e2, e3, e4) + dma_sync_sg_for_cpu(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4; @@ - pci_dma_sync_sg_for_device(e1, e2, e3, e4) + dma_sync_sg_for_device(&e1->dev, e2, e3, e4) @@ expression e1, e2; @@ - pci_dma_mapping_error(e1, e2) + dma_mapping_error(&e1->dev, e2) @@ expression e1, e2; @@ - pci_set_dma_mask(e1, e2) + dma_set_mask(&e1->dev, e2) @@ expression e1, e2; @@ - pci_set_consistent_dma_mask(e1, e2) + dma_set_coherent_mask(&e1->dev, e2) Link: https://lore.kernel.org/r/95afc589713ade2110e7812159ce3e9ab453ec18.1623568121.git.christophe.jaillet@wanadoo.fr Signed-off-by:

mptsas_cleanup_fw_event_q() uses in_interrupt() to determine if it is safe to cancel a worker item. 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.

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. >From reading the mpt_config() code and the history this is clearly a debug mechanism and should probably be replaced by might_sleep() or completely removed because such checks are already in the subsequent functions.

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.

The sense data buffer in sense_buf_pool is allocated with size of MPT_SENSE_BUFFER_ALLOC(64) (multiplied by req_depth) while SNS_LEN(sc)(96) is used when reading the data. 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.

Since commit 84af7a61 ("checkpatch: kconfig: prefer 'help' over '---help---'"), the number of '---help---' has been gradually decreasing, but there are still more than 2400 instances. This commit finishes the conversion. While I touched the lines, I also fixed the indentation. There are a variety of indentation styles found. a) 4 spaces + '---help---' b) 7 spaces + '---help---' c) 8 spaces + '---help---' d) 1 space + 1 tab + '---help---' e) 1 tab + '---help---' (correct indentation) f) 1 tab + 1 space + '---help---' g) 1 tab + 2 spaces + '---help---' In order to convert all of them to 1 tab + 'help', I ran the following commend: $ find . -name 'Kconfig*' | xargs sed -i 's/^[[:space:]]*---help---/\thelp/' Signed-off-by:

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.

When driver debugging is not enabled, change the debug print macros to use the no_printk() macro. This fixes a gcc warning when -Wextra is set: ../drivers/message/fusion/mptlan.c:266:39: warning: suggest braces around empty body in an ‘else’ statement [-Wempty-body] I have verified that there is very little object code change (with gcc 7.5.0).

Tom Hatskevich reported that we look up "iocp" then, in the called functions we do a second copy_from_user() and look it up again. 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.
