commit 8e71a322 upstream. If a device is halted and reuturns a STALL, then the halted endpoint needs to be cleared both on the host and device side. The host side halt is cleared by issueing a xhci reset endpoint command. The device side is cleared with a ClearFeature(ENDPOINT_HALT) request, which should be issued by the device driver if a URB reruen -EPIPE. Previously we cleared the host side halt after the device side was cleared. To make sure the host side halt is cleared in time we want to issue the reset endpoint command immedialtely when a STALL status is encountered. Otherwise we end up not following the specs and not returning -EPIPE several times in a row when trying to transfer data to a halted endpoint. Fixes: bcef3fd5 (USB: xhci: Handle errors that cause endpoint halts.) Tested-by:

commit c3492dbf upstream. A halted endpoint ring must first be reset, then move the ring dequeue pointer past the problematic TRB. If we start the ring too early after reset, but before moving the dequeue pointer we will end up executing the same problematic TRB again. As we always issue a set transfer dequeue command after a reset endpoint command we can skip starting endpoint rings at reset endpoint command completion. Without this fix we end up trying to handle the same faulty TD for contol endpoints. causing timeout, and failing testusb ctrl_out write tests. Fixes: e9df17eb (USB: xhci: Correct assumptions about number of rings per endpoint.) Tested-by:

commit ef59a20b upstream. According to the manuals I have, XScale auxiliary register should be reached with opc_2 = 1 instead of crn = 1. cpu_xscale_proc_init correctly uses c1, c0, 1 arguments, but cpu_xscale_do_suspend and cpu_xscale_do_resume use c1, c1, 0. Correct suspend/resume functions to also use c1, c0, 1. The issue was primarily noticed thanks to qemu reporing "unsupported instruction" on the pxa suspend path. Confirmed in PXA210/250 and PXA255 XScale Core manuals and in PXA270 and PXA320 Developers Guides. Harware tested by me on tosa (pxa255). Robert confirmed on pxa270 board. Tested-by:

commit 01a4cc4d upstream. In some cases, the fcoe_rx_list may contains multiple instances of the same skb (the so called "shared skbs"). the bnx2fc_l2_rcv thread is a loop that extracts a skb from the list, modifies (and destroys) its content and then proceed to the next one. The problem is that if the skb is shared, the remaining instances will be corrupted. The solution is to use skb_share_check() before adding the skb to the fcoe_rx_list.

commit e6d5e7d9 upstream. Commit 79c6ab50 (clk: divider: add CLK_DIVIDER_READ_ONLY flag) in v3.16 introduced the CLK_DIVIDER_READ_ONLY flag which caused the recalc_rate() and round_rate() clock callbacks to be omitted. However using this flag has the unfortunate side effect of causing the clock recalculation code when a clock rate change is attempted to always treat it as a pass-through clock, i.e. with a fixed divide of 1, which may not be the case. Child clock rates are then recalculated using the wrong parent rate. Therefore instead of dropping the recalc_rate() and round_rate() callbacks, alter clk_divider_bestdiv() to always report the current divider as the best divider so that it is never altered. For me the read only clock was the system clock, which divided the PLL rate by 2, from which both the UART and the SPI clocks were divided. Initial setting of the UART rate set it correctly, but when the SPI clock was set, the other child clocks were miscalculated. The UART clock was recalculated using the PLL rate as the parent rate, resulting in a UART new_rate of double what it should be, and a UART which spewed forth garbage when the rate changes were propagated.

commit c1aefbdd upstream. We can only use page_address on memory that has been mapped using kmap, when the buffer passed to the SPI has been allocated by vmalloc the page has not necessarily been mapped through kmap. This means sometimes page_address will return NULL causing the pointer we pass to sg_set_buf to be invalid. As we only call page_address so that we can pass a virtual address to sg_set_buf which will then immediately call virt_to_page on it, fix this by calling sg_set_page directly rather then relying on the sg_set_buf helper.

commit 0a8727e6 upstream. An IOCTL call that calls spi_setup() and then dw_spi_setup() will overwrite the persisted last transfer speed. On each transfer, the SPI speed is compared to the last transfer speed to determine if the clock divider registers need to be updated (did the speed change?). This bug was observed with the spidev driver using spi-config to update the max transfer speed. This fix: Don't overwrite the persisted last transaction clock speed when updating the SPI parameters in dw_spi_setup(). On the next transaction, the new speed won't match the persisted last speed and the hardware registers will be updated. On initialization, the persisted last transaction clock speed will be 0 but will be updated after the first SPI transaction. Move zeroed clock divider check into clock change test because chip->clk_div is zero on startup and would cause a divide-by-zero error. The calculation was wrong as well (can't support odd #).

commit 835f252c upstream. https://bugzilla.kernel.org/show_bug.cgi?id=86831 Markus reported that when shutting down mysqld (with AIO support, on a ext3 formatted Harddrive) leads to a negative number of dirty pages (underrun to the counter). The negative number results in a drastic reduction of the write performance because the page cache is not used, because the kernel thinks it is still 2 ^ 32 dirty pages open. Add a warn trace in __dec_zone_state will catch this easily: static inline void __dec_zone_state(struct zone *zone, enum zone_stat_item item) { atomic_long_dec(&zone->vm_stat[item]); + WARN_ON_ONCE(item == NR_FILE_DIRTY && atomic_long_read(&zone->vm_stat[item]) < 0); atomic_long_dec(&vm_stat[item]); } [ 21.341632] ------------[ cut here ]------------ [ 21.346294] WARNING: CPU: 0 PID: 309 at include/linux/vmstat.h:242 cancel_dirty_page+0x164/0x224() [ 21.355296] Modules linked in: wutbox_cp sata_mv [ 21.359968] CPU: 0 PID: 309 Comm: kworker/0:1 Not tainted 3.14.21-WuT #80 [ 21.366793] Workqueue: events free_ioctx [ 21.370760] [<c0016a64>] (unwind_backtrace) from [<c0012f88>] (show_stack+0x20/0x24) [ 21.378562] [<c0012f88>] (show_stack) from [<c03f8ccc>] (dump_stack+0x24/0x28) [ 21.385840] [<c03f8ccc>] (dump_stack) from [<c0023ae4>] (warn_slowpath_common+0x84/0x9c) [ 21.393976] [<c0023ae4>] (warn_slowpath_common) from [<c0023bb8>] (warn_slowpath_null+0x2c/0x34) [ 21.402800] [<c0023bb8>] (warn_slowpath_null) from [<c00c0688>] (cancel_dirty_page+0x164/0x224) [ 21.411524] [<c00c0688>] (cancel_dirty_page) from [<c00c080c>] (truncate_inode_page+0x8c/0x158) [ 21.420272] [<c00c080c>] (truncate_inode_page) from [<c00c0a94>] (truncate_inode_pages_range+0x11c/0x53c) [ 21.429890] [<c00c0a94>] (truncate_inode_pages_range) from [<c00c0f6c>] (truncate_pagecache+0x88/0xac) [ 21.439252] [<c00c0f6c>] (truncate_pagecache) from [<c00c0fec>] (truncate_setsize+0x5c/0x74) [ 21.447731] [<c00c0fec>] (truncate_setsize) from [<c013b3a8>] (put_aio_ring_file.isra.14+0x34/0x90) [ 21.456826] [<c013b3a8>] (put_aio_ring_file.isra.14) from [<c013b424>] (aio_free_ring+0x20/0xcc) [ 21.465660] [<c013b424>] (aio_free_ring) from [<c013b4f4>] (free_ioctx+0x24/0x44) [ 21.473190] [<c013b4f4>] (free_ioctx) from [<c003d8d8>] (process_one_work+0x134/0x47c) [ 21.481132] [<c003d8d8>] (process_one_work) from [<c003e988>] (worker_thread+0x130/0x414) [ 21.489350] [<c003e988>] (worker_thread) from [<c00448ac>] (kthread+0xd4/0xec) [ 21.496621] [<c00448ac>] (kthread) from [<c000ec18>] (ret_from_fork+0x14/0x20) [ 21.503884] ---[ end trace 79c4bf42c038c9a1 ]--- The cause is that we set the aio ring file pages as *DIRTY* via SetPageDirty (bypasses the VFS dirty pages increment) when init, and aio fs uses *default_backing_dev_info* as the backing dev, which does not disable the dirty pages accounting capability. So truncating aio ring file will contribute to accounting dirty pages (VFS dirty pages decrement), then error occurs. The original goal is keeping these pages in memory (can not be reclaimed or swapped) in life-time via marking it dirty. But thinking more, we have already pinned pages via elevating the page's refcount, which can already achieve the goal, so the SetPageDirty seems unnecessary. In order to fix the issue, using the __set_page_dirty_no_writeback instead of the nop .set_page_dirty, and dropped the SetPageDirty (don't manually set the dirty flags, don't disable set_page_dirty(), rely on default behaviour). With the above change, the dirty pages accounting can work well. But as we known, aio fs is an anonymous one, which should never cause any real write-back, we can ignore the dirty pages (write back) accounting by disabling the dirty pages (write back) accounting capability. So we introduce an aio private backing dev info (disabled the ACCT_DIRTY/WRITEBACK/ACCT_WB capabilities) to replace the default one. Reported-by:

commit ded94779 upstream. For LPAE, we have the following means for encoding writable or dirty ptes: L_PTE_DIRTY L_PTE_RDONLY !pte_dirty && !pte_write 0 1 !pte_dirty && pte_write 0 1 pte_dirty && !pte_write 1 1 pte_dirty && pte_write 1 0 So we can't distinguish between writeable clean ptes and read only ptes. This can cause problems with ptes being incorrectly flagged as read only when they are writeable but not dirty. This patch renumbers L_PTE_RDONLY from AP[2] to a software bit #58, and adds additional logic to set AP[2] whenever the pte is read only or not dirty. That way we can distinguish between clean writeable ptes and read only ptes. HugeTLB pages will use this new logic automatically. We need to add some logic to Transparent HugePages to ensure that they correctly interpret the revised pgprot permissions (L_PTE_RDONLY has moved and no longer matches PMD_SECT_AP2). In the process of revising THP, the names of the PMD software bits have been prefixed with L_ to make them easier to distinguish from their hardware bit counterparts. Signed-off-by:

commit f2950706 upstream. Long descriptors on ARM are 64 bits, and some pte functions such as pte_dirty return a bitwise-and of a flag with the pte value. If the flag to be tested resides in the upper 32 bits of the pte, then we run into the danger of the result being dropped if downcast. For example: gather_stats(page, md, pte_dirty(*pte), 1); where pte_dirty(*pte) is downcast to an int. This patch introduces a new macro pte_isset which performs the bitwise and, then performs a double logical invert (where needed) to ensure predictable downcasting. The logical inverse pte_isclear is also introduced. Equivalent pmd functions for Transparent HugePages have also been added. Signed-off-by:

commit 8500d791 upstream. btmrvl_add_card() function calls kthread_run that might return error (e.g. if current thread is killed). If one tries to use the error value as a pointer then invalid memory access oops happens. Check kthread_run() return value, if it is an error then release resources correctly. TEST=boot computer with BT modules enabled. I see the error message that BT device initialization failed. Now kernel does not crash. Hint: to enable BT run 'rmmod btmrvl_sdio; modprobe btmrvl_sdio' Signed-off-by:

commit 72dd2b2a upstream. The ath3k driver is treating the version information badly when it comes to loading the right firmware version and comparing that it actually matches with the hardware. Initially this showed up as this: CHECK drivers/bluetooth/ath3k.c drivers/bluetooth/ath3k.c:373:17: warning: cast to restricted __le32 drivers/bluetooth/ath3k.c:435:17: warning: cast to restricted __le32 However when fixing this by actually using __packed and __le32 for the ath3_version structure, more issues came up: CHECK drivers/bluetooth/ath3k.c drivers/bluetooth/ath3k.c:381:32: warning: incorrect type in assignment (different base types) drivers/bluetooth/ath3k.c:381:32: expected restricted __le32 [usertype] rom_version drivers/bluetooth/ath3k.c:381:32: got int [signed] <noident> drivers/bluetooth/ath3k.c:382:34: warning: incorrect type in assignment (different base types) drivers/bluetooth/ath3k.c:382:34: expected restricted __le32 [usertype] build_version drivers/bluetooth/ath3k.c:382:34: got int [signed] <noident> drivers/bluetooth/ath3k.c:386:28: warning: restricted __le32 degrades to integer drivers/bluetooth/ath3k.c:386:56: warning: restricted __le32 degrades to integer This patch fixes every instance of the firmware version handling and makes sure it is endian safe and uses proper unaligned access.

commit 40df783d upstream. Intel Bluetooth devices that boot up in bootloader mode can not be used as generic HCI devices, but their HCI transport is still valuable and so bring that up as raw-only devices.
