Sebastian Ott and Gerald Schaefer reported random crashes on s390. It was bisected to my THP refcounting patchset. The problem is that pmdp_invalidated() called with wrong virtual address. It got offset up by HPAGE_PMD_SIZE by loop over ptes. The solution is to introduce new variable to be used in loop and don't touch 'haddr'. Signed-off-by: NKirill A.

In commit 11f1a4b9 ("x86: reorganize SMAP handling in user space accesses") I changed how the stac/clac instructions were generated around the user space accesses, which then made it possible to do batched accesses efficiently for user string copies etc. However, in doing so, I completely spaced out, and didn't even think about the 32-bit case. And nobody really even seemed to notice, because SMAP doesn't even exist until modern Skylake processors, and you'd have to be crazy to run 32-bit kernels on a modern CPU. Which brings us to Andy Lutomirski. He actually tested the 32-bit kernel on new hardware, and noticed that it doesn't work. My bad. The trivial fix is to add the required uaccess begin/end markers around the raw accesses in <asm/uaccess_32.h>. I feel a bit bad about this patch, just because that header file really should be cleaned up to avoid all the duplicated code in it, and this commit just expands on the problem. But this just fixes the bug without any bigger cleanup surgery. Reported-and-tested-by: NAndy Lutomirski <luto@kernel.org> Signed-off-by: NLinus Torvalds <torvalds@linux-foundation.org>

Replace another case where the layout 'plh_block_lgets' can trigger infinite loops in send_layoutget(). Signed-off-by: NTrond Myklebust <trond.myklebust@primarydata.com>
-
由 Trond Myklebust 提交于
If the server reboots while there is a layoutget outstanding, then the call to pnfs_choose_layoutget_stateid() will fail with an EAGAIN error, which causes an infinite loop in send_layoutget(). The reason why we never break out of the loop is that the layout 'plh_block_lgets' field is never cleared. Fix is to replace plh_block_lgets with NFS_LAYOUT_INVALID_STID, which can be reset after a new layoutget. Fixes: ab7d763e ("pNFS: Ensure nfs4_layoutget_prepare returns...")

The dm9000 driver doesn't work in at least one device-tree configuration, spitting an error message on irq resource : [ 1.062495] dm9000 8000000.ethernet: insufficient resources [ 1.068439] dm9000 8000000.ethernet: not found (-2). [ 1.073451] dm9000: probe of 8000000.ethernet failed with error -2 The reason behind is that the interrupt might be provided by a gpio controller, not probed when dm9000 is probed, and needing the probe deferral mechanism to apply. Currently, the interrupt is directly taken from resources. This patch changes this to use the more generic platform_get_irq(), which handles the deferral. Moreover, since commit Fixes: 7085a740 ("drivers: platform: parse IRQ flags from resources"), the interrupt trigger flags are honored in platform_get_irq(), so remove the needless code in dm9000.

The commit 89907779 ("netcp: try to reduce type confusion in descriptors") introduces a regression in Kernel 4.5-rc1 and it breaks get/set_pad_info() functionality. The TI NETCP driver uses pad0 and pad1 fields of knav_dma_desc to store DMA/MEM buffer pointer and buffer size respectively. And in both cases for Keystone 2 the pointer type size is 32 bit regardless of LAPE enabled or not, because CONFIG_ARCH_DMA_ADDR_T_64BIT originally is not expected to be defined. Unfortunately, above commit changed buffer's pointers save/restore code (get/set_pad_info()) and added intermediate conversation to u64 which works incorrectly on 32bit Keystone 2 and causes TI NETCP driver crash in RX/TX path due to "Unable to handle kernel NULL pointer" exception. This issue was reported and discussed in [1]. Hence, fix it by partially reverting above commit and restoring get/set_pad_info() functionality as it was before.

Dmitry Vyukov noted recently that the sctp_port_hashtable had an error in its size computation, observing that the current method never guaranteed that the hashsize (measured in number of entries) would be a power of two, which the input hash function for that table requires. The root cause of the problem is that two values need to be computed (one, the allocation order of the storage requries, as passed to __get_free_pages, and two the number of entries for the hash table). Both need to be ^2, but for different reasons, and the existing code is simply computing one order value, and using it as the basis for both, which is wrong (i.e. it assumes that ((1<<order)*PAGE_SIZE)/sizeof(bucket) is still ^2 when its not). To fix this, we change the logic slightly. We start by computing a goal allocation order (which is limited by the maximum size hash table we want to support. Then we attempt to allocate that size table, decreasing the order until a successful allocation is made. Then, with the resultant successful order we compute the number of buckets that hash table supports, which we then round down to the nearest power of two, giving us the number of entries the table actually supports. I've tested this locally here, using non-debug and spinlock-debug kernels, and the number of entries in the hashtable consistently work out to be powers of two in all cases.

This patch fixes the problem that more CAN messages could be sent to the interface as could be send on the CAN bus. This was more likely for slow baud rates. The sleeping _start_xmit was woken up in the _write_bulk_callback. Under heavy TX load this produced another bulk transfer without checking the free_slots variable and hence caused the overflow in the interface.

Pull x86 fixes from Ingo Molnar: "This is unusually large, partly due to the EFI fixes that prevent accidental deletion of EFI variables through efivarfs that may brick machines. These fixes are somewhat involved to maintain compatibility with existing install methods and other usage modes, while trying to turn off the 'rm -rf' bricking vector.
