587198b Christoph Lameter 22 January 2016, 16:46:14 UTC vmstat: Remove BUG_ON from vmstat_update If we detect that there is nothing to do just set the flag and do not check if it was already set before. Races really do not matter. If the flag is set by any code then the shepherd will start dealing with the situation and reenable the vmstat workers when necessary again. Since commit 0eb77e988032 ("vmstat: make vmstat_updater deferrable again and shut down on idle") quiet_vmstat might update cpu_stat_off and mark a particular cpu to be handled by vmstat_shepherd. This might trigger a VM_BUG_ON in vmstat_update because the work item might have been sleeping during the idle period and see the cpu_stat_off updated after the wake up. The VM_BUG_ON is therefore misleading and no more appropriate. Moreover it doesn't really suite any protection from real bugs because vmstat_shepherd will simply reschedule the vmstat_work anytime it sees a particular cpu set or vmstat_update would do the same from the worker context directly. Even when the two would race the result wouldn't be incorrect as the counters update is fully idempotent.

Rozycki 22 January 2016, 05:20:46 UTC MIPS: math-emu: Make microMIPS branch delay slot emulation work Complement commit 102cedc32a6e ("MIPS: microMIPS: Floating point support.") which introduced microMIPS FPU emulation, but did not adjust the encoding of the BREAK instruction used to terminate the branch delay slot emulation frame. Consequently the execution of any such frame is indeterminate and, depending on CPU configuration, will result in random code execution or an offending program being terminated with SIGILL. This is because the regular MIPS BREAK instruction is encoded with the 0 major and the 0xd minor opcode, however in the microMIPS instruction set this major/minor opcode pair denotes an encoding reserved for the DSP ASE. Instead the microMIPS BREAK instruction is encoded with the 0 major and the 0x7 minor opcode. Use the correct BREAK encoding for microMIPS FPU emulation then. Signed-off-by: Maciej W.

Consider this program: static double div(double d) { do d /= 2.0; while (d > .5); return d; } int main(int argc, char **argv) { return div(argc); } which gets compiled to the following binary code: 00400490 <main>: 400490: 44840000 mtc1 a0,$f0 400494: 3c020040 lui v0,0x40 400498: d44207f8 ldc1 $f2,2040(v0) 40049c: 46800021 cvt.d.w $f0,$f0 4004a0: 46220002 mul.d $f0,$f0,$f2 4004a4: 4620103c c.lt.d $f2,$f0 4004a8: 4501fffd bc1t 4004a0 <main+0x10> 4004ac: 00000000 nop 4004b0: 4620000d trunc.w.d $f0,$f0 4004b4: 03e00008 jr ra 4004b8: 44020000 mfc1 v0,$f0 4004bc: 00000000 nop Where the FPU emulator is used, depending on the number of command-line arguments this code will either run to completion or terminate with SIGILL. If no arguments are specified, then BC1T will not be taken, NOP will not be emulated and code will complete successfully. If one argument is specified, then BC1T will be taken once and NOP will be emulated. At this point the entry PC value will be 0x400498 and the new PC value, set by `mips_dsemul' will be 0x4004a0, the target of BC1T. The emulation loop will terminate, but SIGILL will not be issued, because the PC has changed. The FPU emulator will be entered again and on the second execution BC1T will not be taken, NOP will not be emulated and code will complete successfully. If two or more arguments are specified, then the first execution of BC1T will proceed as above. Upon reentering the FPU emulator the emulation loop will continue to BC1T, at which point the branch will be taken and NOP emulated again. At this point however the entry PC value will be 0x4004a0, the same as the target of BC1T. This will make the emulator conclude that execution has not advanced and therefore an unsupported FPU instruction has been encountered, and SIGILL will be sent to the process. Fix the problem by extending the internal API of `mips_dsemul', making it return -1 if no delay slot emulation frame has been made, the instruction has been handled and execution of the emulation loop needs to continue as if nothing happened. Remove code from `mips_dsemul' to reproduce steps made by the emulation loop at the conclusion of each iteration, as those will be reached normally now. Adjust call sites accordingly. Document the API. Signed-off-by: Maciej W.

db0dbd5 Huacai Chen 21 January 2016, 13:09:51 UTC MIPS: sync-r4k: reduce skew while synchronization While synchronization, count register will go backwards for the master. If synchronise_count_master() runs before synchronise_count_slave(), skew becomes even more. The skew is very harmful for CPU hotplug (CPU0 do synchronization with CPU1, then CPU0 do synchronization with CPU2 and CPU0's count goes backwards, so it will be out of sync with CPU1). After the commit cf9bfe55f24973a8f40e2 (MIPS: Synchronize MIPS count one CPU at a time), we needn't evaluate count_reference at the beginning of synchronise_count_master() any more. Thus, we evaluate the initcount (It seems like count_reference is redundant) in the 2nd loop. Since we write the count register in the last loop, we don't need additional barriers (the existing memory barriers are enough). Moreover, I think we loop 3 times is enough to get a primed instruction cache, this can also get less skew than looping 5 times. Comments are also updated in this patch.

eab95db Ross Zwisler 22 January 2016, 23:10:59 UTC dax: never rely on bh.b_dev being set by get_block() Previously in DAX we assumed that calls to get_block() would set bh.b_bdev, and we would then use that value even in error cases for debugging. This caused a NULL pointer dereference in __dax_dbg() which was fixed by a previous commit, but that commit only changed the one place where we were hitting an error. Instead, update dax.c so that we always initialize bh.b_bdev as best we can based on the information that DAX has. get_block() may or may not update to a new value, but this at least lets us get something helpful from bh.b_bdev for error messages and not have to worry about whether it was set by get_block() or not.

f9fe48b Ross Zwisler 22 January 2016, 23:10:40 UTC dax: support dirty DAX entries in radix tree Add support for tracking dirty DAX entries in the struct address_space radix tree. This tree is already used for dirty page writeback, and it already supports the use of exceptional (non struct page*) entries. In order to properly track dirty DAX pages we will insert new exceptional entries into the radix tree that represent dirty DAX PTE or PMD pages. These exceptional entries will also contain the writeback addresses for the PTE or PMD faults that we can use at fsync/msync time. There are currently two types of exceptional entries (shmem and shadow) that can be placed into the radix tree, and this adds a third. We rely on the fact that only one type of exceptional entry can be found in a given radix tree based on its usage. This happens for free with DAX vs shmem but we explicitly prevent shadow entries from being added to radix trees for DAX mappings. The only shadow entries that would be generated for DAX radix trees would be to track zero page mappings that were created for holes.

3f4a267 Ross Zwisler 22 January 2016, 23:10:37 UTC pmem: add wb_cache_pmem() to the PMEM API __arch_wb_cache_pmem() was already an internal implementation detail of the x86 PMEM API, but this functionality needs to be exported as part of the general PMEM API to handle the fsync/msync case for DAX mmaps. One thing worth noting is that we really do want this to be part of the PMEM API as opposed to a stand-alone function like clflush_cache_range() because of ordering restrictions. By having wb_cache_pmem() as part of the PMEM API we can leave it unordered, call it multiple times to write back large amounts of memory, and then order the multiple calls with a single wmb_pmem().

de14b9c Ross Zwisler 22 January 2016, 23:10:34 UTC dax: fix conversion of holes to PMDs When we get a DAX PMD fault for a write it is possible that there could be some number of 4k zero pages already present for the same range that were inserted to service reads from a hole. These 4k zero pages need to be unmapped from the VMAs and removed from the struct address_space radix tree before the real DAX PMD entry can be inserted. For PTE faults this same use case also exists and is handled by a combination of unmap_mapping_range() to unmap the VMAs and delete_from_page_cache() to remove the page from the address_space radix tree. For PMD faults we do have a call to unmap_mapping_range() (protected by a buffer_new() check), but nothing clears out the radix tree entry. The buffer_new() check is also incorrect as the current ext4 and XFS filesystem code will never return a buffer_head with BH_New set, even when allocating new blocks over a hole. Instead the filesystem will zero the blocks manually and return a buffer_head with only BH_Mapped set. Fix this situation by removing the buffer_new() check and adding a call to truncate_inode_pages_range() to clear out the radix tree entries before we insert the DAX PMD.

d4bbe70 Ross Zwisler 22 January 2016, 23:10:31 UTC dax: fix NULL pointer dereference in __dax_dbg() In __dax_pmd_fault() we currently assume that get_block() will always set bh.b_bdev and we unconditionally dereference it in __dax_dbg(). This assumption isn't always true - when called for reads of holes ext4_dax_mmap_get_block() returns a buffer head where bh->b_bdev is never set. I hit this BUG while testing the DAX PMD fault path. Instead, initialize bh.b_bdev before passing bh into get_block(). It is possible that the filesystem's get_block() will update bh.b_bdev, and this is fine - we just want to initialize bh.b_bdev to something reasonable so that the calls to __dax_dbg() work and print something useful.
