2019-01-04dma-mapping: implement dmam_alloc_coherent using dmam_alloc_attrsChristoph Hellwig
dmam_alloc_coherent is just the default no-flags case of dmam_alloc_attrs, so take advantage of this similar to the non-managed version. Signed-off-by: Christoph Hellwig <hch@lst.de>
2019-01-04dma-mapping: implement dma_map_single_attrs using dma_map_page_attrsChristoph Hellwig
And also switch the way we implement the unmap side around to stay consistent. This ensures dma-debug works again because it records which function we used for mapping to ensure it is also used for unmapping, and also reduces further code duplication. Last but not least this also officially allows calling dma_sync_single_* for mappings created using dma_map_page, which is perfectly fine given that the sync calls only take a dma_addr_t, but not a virtual address or struct page.

2019-01-03Remove 'type' argument from access_ok() functionLinus Torvalds
Nobody has actually used the type (VERIFY_READ vs VERIFY_WRITE) argument of the user address range verification function since we got rid of the old racy i386-only code to walk page tables by hand. It existed because the original 80386 would not honor the write protect bit when in kernel mode, so you had to do COW by hand before doing any user access. But we haven't supported that in a long time, and these days the 'type' argument is a purely historical artifact. A discussion about extending 'user_access_begin()' to do the range checking resulted this patch, because there is no way we're going to move the old VERIFY_xyz interface to that model. And it's best done at the end of the merge window when I've done most of my merges, so let's just get this done once and for all. This patch was mostly done with a sed-script, with manual fix-ups for the cases that weren't of the trivial 'access_ok(VERIFY_xyz' form. There were a couple of notable cases: - csky still had the old "verify_area()" name as an alias. - the iter_iov code had magical hardcoded knowledge of the actual values of VERIFY_{READ,WRITE} (not that they mattered, since nothing really used it) - microblaze used the type argument for a debug printout but other than those oddities this should be a total no-op patch. I tried to fix up all architectures, did fairly extensive grepping for access_ok() uses, and the changes are trivial, but I may have missed something. Any missed conversion should be trivially fixable, though. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2019-01-03perf stat: Fix endless wait for child processJin Yao
We hit a 'perf stat' issue by using following script: #!/bin/bash sleep 1000 & exec perf stat -a -e cycles -I1000 -- sleep 5 Since "perf stat" is launched by exec, the "sleep 1000" would be the child process of "perf stat". The wait4() call will not return because it's waiting for the child process "sleep 1000" to end. So 'perf stat' doesn't return even after 5s passes. This patch lets 'perf stat' return when the specified child process ends (in this case, the specified child process is "sleep 5"). Committer testing: # cat test.sh #!/bin/bash sleep 10 & exec perf stat -a -e cycles -I1000 -- sleep 5 # Before: # time ./test.sh # time counts unit events 1.001113090 108,453,351 cycles 2.002062196 142,075,435 cycles 3.002896194 164,801,068 cycles 4.003731666 107,062,140 cycles 5.002068867 112,241,832 cycles real 0m10.066s user 0m0.016s sys 0m0.101s # After: # time ./test.sh # time counts unit events 1.001016096 91,412,027 cycles 2.002014963 124,063,708 cycles 3.002883964 125,993,929 cycles 4.003706470 120,465,734 cycles 5.002006778 163,560,355 cycles real 0m5.123s user 0m0.014s sys 0m0.105s # Signed-off-by: Jin Yao <yao.jin@linux.intel.com> Reviewed-by: Jiri Olsa <jolsa@kernel.org> Tested-by: Arnaldo Carvalho de Melo <acme@redhat.com> Cc: Alexander Shishkin <alexander.shishkin@linux.intel.com> Cc: Andi Kleen <ak@linux.intel.com> Cc: Kan Liang <kan.liang@linux.intel.com> Cc: Peter Zijlstra <peterz@infradead.org> Link: http://lkml.kernel.org/r/1546501245-4512-1-git-send-email-yao.jin@linux.intel.com Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>

2019-01-03ACPI: NUMA: Use correct type for printing addresses on i386-PAEChao Fan
The addresses of NUMA nodes are not printed correctly on i386-PAE which is misleading. Here is a debian9-32bit with PAE in a QEMU guest having more than 4G of memory: qemu-system-i386 \ -hda /var/lib/libvirt/images/debian32.qcow2 \ -m 5G \ -enable-kvm \ -smp 10 \ -numa node,mem=512M,nodeid=0,cpus=0 \ -numa node,mem=512M,nodeid=1,cpus=1 \ -numa node,mem=512M,nodeid=2,cpus=2 \ -numa node,mem=512M,nodeid=3,cpus=3 \ -numa node,mem=512M,nodeid=4,cpus=4 \ -numa node,mem=512M,nodeid=5,cpus=5 \ -numa node,mem=512M,nodeid=6,cpus=6 \ -numa node,mem=512M,nodeid=7,cpus=7 \ -numa node,mem=512M,nodeid=8,cpus=8 \ -numa node,mem=512M,nodeid=9,cpus=9 \ -serial stdio Because of the wrong value type, it prints as below: [ 0.021049] ACPI: SRAT Memory (0x0 length 0xa0000) in proximity domain 0 enabled [ 0.021740] ACPI: SRAT Memory (0x100000 length 0x1ff00000) in proximity domain 0 enabled [ 0.022425] ACPI: SRAT Memory (0x20000000 length 0x20000000) in proximity domain 1 enabled [ 0.023092] ACPI: SRAT Memory (0x40000000 length 0x20000000) in proximity domain 2 enabled [ 0.023764] ACPI: SRAT Memory (0x60000000 length 0x20000000) in proximity domain 3 enabled [ 0.024431] ACPI: SRAT Memory (0x80000000 length 0x20000000) in proximity domain 4 enabled [ 0.025104] ACPI: SRAT Memory (0xa0000000 length 0x20000000) in proximity domain 5 enabled [ 0.025791] ACPI: SRAT Memory (0x0 length 0x20000000) in proximity domain 6 enabled [ 0.026412] ACPI: SRAT Memory (0x20000000 length 0x20000000) in proximity domain 7 enabled [ 0.027118] ACPI: SRAT Memory (0x40000000 length 0x20000000) in proximity domain 8 enabled [ 0.027802] ACPI: SRAT Memory (0x60000000 length 0x20000000) in proximity domain 9 enabled The upper half of the start address of the NUMA domains between 6 and 9 inclusive was cut, so the printed values are incorrect. Fix the value type, to get the correct values in the log as follows: [ 0.023698] ACPI: SRAT Memory (0x0 length 0xa0000) in proximity domain 0 enabled [ 0.024325] ACPI: SRAT Memory (0x100000 length 0x1ff00000) in proximity domain 0 enabled [ 0.024981] ACPI: SRAT Memory (0x20000000 length 0x20000000) in proximity domain 1 enabled [ 0.025659] ACPI: SRAT Memory (0x40000000 length 0x20000000) in proximity domain 2 enabled [ 0.026317] ACPI: SRAT Memory (0x60000000 length 0x20000000) in proximity domain 3 enabled [ 0.026980] ACPI: SRAT Memory (0x80000000 length 0x20000000) in proximity domain 4 enabled [ 0.027635] ACPI: SRAT Memory (0xa0000000 length 0x20000000) in proximity domain 5 enabled [ 0.028311] ACPI: SRAT Memory (0x100000000 length 0x20000000) in proximity domain 6 enabled [ 0.028985] ACPI: SRAT Memory (0x120000000 length 0x20000000) in proximity domain 7 enabled [ 0.029667] ACPI: SRAT Memory (0x140000000 length 0x20000000) in proximity domain 8 enabled [ 0.030334] ACPI: SRAT Memory (0x160000000 length 0x20000000) in proximity domain 9 enabled Signed-off-by: Chao Fan <fanc.fnst@cn.fujitsu.com> [ rjw: Subject & changelog ] Signed-off-by: Rafael J.

2019-01-02ipv6: Consider sk_bound_dev_if when binding a socket to an addressDavid Ahern
IPv6 does not consider if the socket is bound to a device when binding to an address. The result is that a socket can be bound to eth0 and then bound to the address of eth1. If the device is a VRF, the result is that a socket can only be bound to an address in the default VRF. Resolve by considering the device if sk_bound_dev_if is set. This problem exists from the beginning of git history. Signed-off-by: David Ahern <dsahern@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2019-01-02ipv6: Fix dump of specific table with strict checkingDavid Ahern
Dump of a specific table with strict checking enabled is looping. The problem is that the end of the table dump is not marked in the cb. When dumping a specific table, cb args 0 and 1 are not used (they are the hash index and entry with an hash table index when dumping all tables). Re-use args[0] to hold a 'done' flag for the specific table dump.
