Pull x86 fixes from Ingo Molnar: "Another round of CR3/PCID related fixes (I think this addresses all but one of the known problems with PCID support), an objtool fix plus a Clang fix that (finally) solves all Clang quirks to build a bootable x86 kernel as-is" * 'x86-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86/asm: Fix inline asm call constraints for Clang objtool: Handle another GCC stack pointer adjustment bug x86/mm/32: Load a sane CR3 before cpu_init() on secondary CPUs x86/mm/32: Move setup_clear_cpu_cap(X86_FEATURE_PCID) earlier x86/mm/64: Stop using CR3.PCID == 0 in ASID-aware code x86/mm: Factor out CR3-building code |

x86/asm: Fix inline asm call constraints for Clang
For inline asm statements which have a CALL instruction, we list the stack pointer as a constraint to convince GCC to ensure the frame pointer is set up first: static inline void foo() { register void *__sp asm(_ASM_SP); asm("call bar" : "+r" (__sp)) } Unfortunately, that pattern causes Clang to corrupt the stack pointer. The fix is easy: convert the stack pointer register variable to a global variable. It should be noted that the end result is different based on the GCC version. With GCC 6.4, this patch has exactly the same result as before: defconfig defconfig-nofp distro distro-nofp before 9820389 9491555 8816046 8516940 after 9820389 9491555 8816046 8516940 With GCC 7.2, however, GCC's behavior has changed. It now changes its behavior based on the conversion of the register variable to a global. That somehow convinces it to *always* set up the frame pointer before inserting *any* inline asm. (Therefore, listing the variable as an output constraint is a no-op and is no longer necessary.) It's a bit overkill, but the performance impact should be negligible. And in fact, there's a nice improvement with frame pointers disabled: defconfig defconfig-nofp distro distro-nofp before 9796316 9468236 9076191 8790305 after 9796957 9464267 9076381 8785949 So in summary, while listing the stack pointer as an output constraint is no longer necessary for newer versions of GCC, it's still needed for older versions.

objtool: Handle another GCC stack pointer adjustment bug

objtool: Fix object file corruption
Arnd Bergmann reported that a randconfig build was failing with the
following link error:
built-in.o: member arch/x86/kernel/time.o in archive is not an object
It turns out the link failed because the time.o file had been corrupted
by objtool:
nm: arch/x86/kernel/time.o: File format not recognized
In certain rare cases, when a .o file's ORC table is very small, the
.data section size doesn't change because it's page aligned. Because
all the existing sections haven't changed size, libelf doesn't detect
any section header changes, and so it doesn't update the section header
table properly. Instead it writes junk in the section header entries
for the new ORC sections.
Make sure libelf properly updates the section header table by setting
the ELF_F_DIRTY flag in the top level elf struct.

It turned out that some other child process exited, but not the one perf stat launched: $ sudo strace -e fork,execve,clone,wait4 -f ./perf-x86_64.AppImage stat sleep 1 execve("./perf-git.3a73b7f9-x86_64.AppImage", ["./perf-git.3a73b7f9-x86_64.AppIm"..., "stat", "sleep", "1"], 0x7ffec1bbf050 /* 18 vars */) = 0 clone(child_stack=NULL, flags=CLONE_CHILD_CLEARTID|CLONE_CHILD_SETTID|SIGCHLD, child_tidptr=0x7f6a6e7efe50) = 3912 strace: Process 3912 attached [pid 3912] clone(child_stack=NULL, flags=CLONE_CHILD_CLEARTID|CLONE_CHILD_SETTID|SIGCHLD, child_tidptr=0x7f6a6e7efe50) = 3914 strace: Process 3914 attached [pid 3912] +++ exited with 0 +++ [pid 3911] --- SIGCHLD {si_signo=SIGCHLD, si_code=CLD_EXITED, si_pid=3912, si_uid=0, si_status=0, si_utime=0, si_stime=0} --- [pid 3914] clone(strace: Process 3915 attached child_stack=0x7f6a6d9fefb0, flags=CLONE_VM|CLONE_FS|CLONE_FILES|CLONE_SIGHAND|CLONE_THREAD|CLONE_SYSVSEM|CLONE_SETTLS|CLONE_PARENT_SETTID|CLONE_CHILD_CLEARTID, parent_tidptr=0x7f6a6d9ff9d0, tls=0x7f6a6d9ff700, child_tidptr=0x7f6a6d9ff9d0) = 3915 [pid 3911] execve("/tmp/.mount_perf-g6VYMpl/AppRun", ["./perf-git.3a73b7f9-x86_64.AppIm"..., "stat", "sleep", "1"], 0x14aab70 /* 21 vars */) = 0 [pid 3911] clone(child_stack=NULL, flags=CLONE_CHILD_CLEARTID|CLONE_CHILD_SETTID|SIGCHLD, child_tidptr=0x7f4ae113c4d0) = 3916 strace: Process 3916 attached [pid 3911] wait4(-1, [{WIFEXITED(s) && WEXITSTATUS(s) == 0}], 0, NULL) = 3912 [pid 3916] execve("/usr/libexec/perf-core/sleep", ["sleep", "1"], 0x27d3650 /* 22 vars */) = -1 ENOENT (No such file or directory) [pid 3916] execve("/tmp/./sleep", ["sleep", "1"], 0x27d3650 /* 22 vars */) = -1 ENOENT (No such file or directory) [pid 3916] execve("/home/milian/.bin/sleep", ["sleep", "1"], 0x27d3650 /* 22 vars */) = -1 ENOENT (No such file or directory) [pid 3916] execve("/usr/lib/icecream/libexec/icecc/bin/sleep", ["sleep", "1"], 0x27d3650 /* 22 vars */) = -1 ENOENT (No such file or directory) [pid 3916] execve("/ssd2/milian/projects/compiled/other/bin/sleep", ["sleep", "1"], 0x27d3650 /* 22 vars */) = -1 ENOENT (No such file or directory) [pid 3916] execve("/home/milian/.bin/kf5/sleep", ["sleep", "1"], 0x27d3650 /* 22 vars */) = -1 ENOENT (No such file or directory) [pid 3916] execve("/ssd2/milian/projects/compiled/kf5/bin/sleep", ["sleep", "1"], 0x27d3650 /* 22 vars */) = -1 ENOENT (No such file or directory) [pid 3916] execve("/home/milian/projects/compiled/other/bin/sleep", ["sleep", "1"], 0x27d3650 /* 22 vars */) = -1 ENOENT (No such file or directory) [pid 3916] execve("/home/milian/projects/compiled/kf5/bin/sleep", ["sleep", "1"], 0x27d3650 /* 22 vars */) = -1 ENOENT (No such file or directory) [pid 3916] execve("/usr/local/sbin/sleep", ["sleep", "1"], 0x27d3650 /* 22 vars */) = -1 ENOENT (No such file or directory) [pid 3916] execve("/usr/local/bin/sleep", ["sleep", "1"], 0x27d3650 /* 22 vars */) = -1 ENOENT (No such file or directory) [pid 3916] execve("/usr/bin/sleep", ["sleep", "1"], 0x27d3650 /* 22 vars */ Performance counter stats for 'sleep 1': <not counted> task-clock <not counted> context-switches <not counted> cpu-migrations <not counted> page-faults <not counted> cycles <not counted> instructions <not counted> branches <not counted> branch-misses 0.000047194 seconds time elapsed [pid 3916] --- SIGTERM {si_signo=SIGTERM, si_code=SI_USER, si_pid=3911, si_uid=0} --- [pid 3916] +++ killed by SIGTERM +++ [pid 3911] --- SIGCHLD {si_signo=SIGCHLD, si_code=CLD_KILLED, si_pid=3916, si_uid=0, si_status=SIGTERM, si_utime=0, si_stime=0} --- [pid 3915] --- SIGPIPE {si_signo=SIGPIPE, si_code=SI_USER, si_pid=3914, si_uid=0} --- [pid 3911] +++ exited with 0 +++ [pid 3915] --- SIGHUP {si_signo=SIGHUP, si_code=SI_USER, si_pid=3914, si_uid=0} --- [pid 3915] +++ exited with 0 +++ +++ exited with 0 +++ This patch uses waitpid instead to ensure the call waits for the debuggee application launched by 'perf stat'.

perf tools: Support running perf binaries with a dash in their name
Previously the part behind "perf-" was interpreted as an internal perf command. If the suffix could not be handled, the execution was stopped. This makes it impossible to launch perf binaries that got renamed to have the `perf-` prefix. This is e.g. the case for appimages (e.g. "perf-x86_64.AppImage"), but would also apply to all other scenarios where users symlink or rename perf themselves: Status quo with the broken behavior: $ ln -s ./perf ./perf-custom-suffix $ ./perf-custom-suffix list cannot handle custom-suffix internally$ Also note the missing newline at the end of the error message. With this patch applied, the above works properly: $ ./perf-custom-suffix list List of pre-defined events (to be used in -e): ...

perf ui progress: Fix progress update
We currently update the 'next' variable only with a single step value. But it's possible the 'adv' update is bigger than single 'step' value.

Unlikely, but we could have ui_progress__init being called with total < 16, which would set the next and step variables to 0.

perf tests: Fix compile when libunwind's unwind.h is available
When cross compiling perf and I want to link against a self-compiled libunwind, I usually make the custom path where the libunwind headers exist visible by adding the libunwind prefix to the include path when compiling perf, i.e.: ~~~~~ $ ls $HOME/projects/compiled/other/include/ libunwind-coredump.h libunwind.h libunwind-x86_64.h libunwind-common.h libunwind-dynamic.h libunwind-ptrace.h unwind.h $ make EXTRA_CFLAGS="-I$HOME/projects/compiled/other/include/ ~~~~~~ Note the `unwind.h` header from libunwind which leads to compile errors when compiling tests/dwarf-unwind.c, since it shadows perf's util/unwind.h: ~~~~~ tests/dwarf-unwind.c:41:32: error: ‘struct unwind_entry’ declared inside parameter list will not be visible outside of this definition or declaration [-Werror] static int unwind_entry(struct unwind_entry *entry, void *arg) ^~~~~~~~~~~~ tests/dwarf-unwind.c: In function ‘unwind_entry’: tests/dwarf-unwind.c:44:22: error: dereferencing pointer to incomplete type ‘struct unwind_entry’ char *symbol = entry->sym ? entry->sym->name : NULL; ^~ tests/dwarf-unwind.c: In function ‘unwind_thread’: tests/dwarf-unwind.c:92:8: error: implicit declaration of function ‘unwind__get_entries’; did you mean ‘unwind_entry’?

Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace
Pull namespace updates from Eric Biederman: "Life has been busy and I have not gotten half as much done this round as I would have liked. I delayed it so that a minor conflict resolution with the mips tree could spend a little time in linux-next before I sent this pull request. This includes two long delayed user namespace changes from Kirill Tkhai. It also includes a very useful change from Serge Hallyn that allows the security capability attribute to be used inside of user namespaces. The practical effect of this is people can now untar tarballs and install rpms in user namespaces. It had been suggested to generalize this and encode some of the namespace information information in the xattr name. Upon close inspection that makes the things that should be hard easy and the things that should be easy more expensive. Then there is my bugfix/cleanup for signal injection that removes the magic encoding of the siginfo union member from the kernel internal si_code. The mips folks reported the case where I had used FPE_FIXME me is impossible so I have remove FPE_FIXME from mips, while at the same time including a return statement in that case to keep gcc from complaining about unitialized variables. I almost finished the work to get make copy_siginfo_to_user a trivial copy to user. The code is available at: git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace.git neuter-copy_siginfo_to_user-v3 But I did not have time/energy to get the code posted and reviewed before the merge window opened. I was able to see that the security excuse for just copying fields that we know are initialized doesn't work in practice there are buggy initializations that don't initialize the proper fields in siginfo.

bpf: add support for sockmap detach programs
The bpf map sockmap supports adding programs via attach commands. This patch adds the detach command to keep the API symmetric and allow users to remove previously added programs. Otherwise the user would have to delete the map and re-add it to get in this state. This also adds a series of additional tests to capture detach operation and also attaching/detaching invalid prog types. API note: socks will run (or not run) programs depending on the state of the map at the time the sock is added. We do not for example walk the map and remove programs from previously attached socks.

powerpc updates for 4.14
Nothing really major this release, despite quite a lot of activity. Just lots of things all over the place. Some things of note include: - Access via perf to a new type of PMU (IMC) on Power9, which can count both core events as well as nest unit events (Memory controller etc). - Optimisations to the radix MMU TLB flushing, mostly to avoid unnecessary Page Walk Cache (PWC) flushes when the structure of the tree is not changing. - Reworks/cleanups of do_page_fault() to modernise it and bring it closer to other architectures where possible. - Rework of our page table walking so that THP updates only need to send IPIs to CPUs where the affected mm has run, rather than all CPUs. - The size of our vmalloc area is increased to 56T on 64-bit hash MMU systems. This avoids problems with the percpu allocator on systems with very sparse NUMA layouts. - STRICT_KERNEL_RWX support on PPC32. - A new sched domain topology for Power9, to capture the fact that pairs of cores may share an L2 cache. - Power9 support for VAS, which is a new mechanism for accessing coprocessors, and initial support for using it with the NX compression accelerator. - Major work on the instruction emulation support, adding support for many new instructions, and reworking it so it can be used to implement the emulation needed to fixup alignment faults. - Support for guests under PowerVM to use the Power9 XIVE interrupt controller. And probably that many things again that are almost as interesting, but I had to keep the list short. Plus the usual fixes and cleanups as always.

selftests/memfd: add memfd_create hugetlbfs selftest
With the addition of hugetlbfs support in memfd_create, the memfd selftests should verify correct functionality with hugetlbfs. Instead of writing a separate memfd hugetlbfs test, modify the memfd_test program to take an optional argument 'hugetlbfs'. If the hugetlbfs argument is specified, basic memfd_create functionality will be exercised on hugetlbfs. If hugetlbfs is not specified, the current functionality of the test is unchanged. Note that many of the tests in memfd_test test file sealing operations. hugetlbfs does not support file sealing, therefore for hugetlbfs all sealing related tests are skipped. In order to test on hugetlbfs, there needs to be preallocated huge pages. A new script (run_tests) is added. This script will first run the existing memfd_create tests. It will then, attempt to allocate the required number of huge pages before running the hugetlbfs test. At the end of testing, it will release any huge pages allocated for testing purposes.

userfaultfd: selftest: exercise UFFDIO_COPY/ZEROPAGE -EEXIST
This will retry the UFFDIO_COPY/ZEROPAGE to verify it returns -EEXIST at the first invocation and then later every 10 seconds. In the filebacked MAP_SHARED case this also verifies the -EEXIST triggered in the filesystem pagecache insertion, if the offset in the file was not a hole. shmem MAP_SHARED tries to index the newly allocated pagecache in the radix tree before checking the pagetable so it doesn't need any assistance to exercise that case. hugetlbfs checks the pmd to be not none before trying to index the hugetlbfs page in the radix tree, so it requires to run UFFDIO_COPY into an alias mapping (the alternative would be to use MADV_DONTNEED to only zap the pagetables, but that doesn't work on hugetlbfs).

selftests: Enhance kselftest_harness.h to print which assert failed
When a test process is not able to write to TH_LOG_STREAM, this step mechanism enable to print the assert number which triggered the failure. This can be enabled by setting _metadata->no_print to true at the beginning of the test sequence. Update the seccomp-bpf test to return 0 if a test succeeded. This feature is needed for the Landlock tests.

spi: Updates for v4.14
A fairly quiet release for the SPI subsystem: - Move to using IDR for allocating bus numbers. - Modernisation of the ep93xx driver, removing a lot of open coding and using the framework more. - The tools have been moved to use the standard tools build system and an install target added (there will be a fairly trivial conflict with tip resulting from the changes in the main tools Makefile). - A refactoring of the Qualcomm QUP driver which enables new variants to be supported. - Explicit support for the Freescale i.MX53 and i.MX6 SPI, Renesas R-Car H3 and Rockchip RV1108 controllers. There's also a trivial add/add conflict in spi.c with the ACPI tree adding a header for some Apple support and the IDR code needing a header too. -----BEGIN PGP SIGNATURE----- iQFHBAABCAAxFiEEreZoqmdXGLWf4p/qJNaLcl1Uh9AFAlmtgGYTHGJyb29uaWVA a2VybmVsLm9yZwAKCRAk1otyXVSH0IwAB/9U/s75RgZN+w/IZneex3gD2+mnNxTV SiWWlR66580vbXsh7lgzTtANrDKfYTsYGP3JS7vjhsegBlzcT4M5OMyJZTcCi40a JF0edDFnkqNM96LubJVnrIJj4KHL1Zx+FICIXItOSBZh6ECgI92KAfAbfQhLdB10 BtNdlsQMzcTygLqf2/N6W7u/6yYBnUuaaNeu+j4QsF1pE9L/5kt3lLXxv2DTL3cA vncqu/ndxIjCKLpIGjMOrvAlLCKmZdIxX3Y/d1XJSxyG3vJj30kEvxATZ15sKln8 gXOnmWF2JgBcxEHxzsTGuVZpXXblu7uiicniglP0geC9dMboJnky993j =tbQ9 -----END PGP SIGNATURE----- Merge tag 'spi-v4.14' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi Pull spi updates from Mark Brown: "A fairly quiet release for the SPI subsystem: - Move to using IDR for allocating bus numbers - Modernisation of the ep93xx driver, removing a lot of open coding and using the framework more - The tools have been moved to use the standard tools build system and an install target added (there will be a fairly trivial conflict with tip resulting from the changes in the main tools Makefile) - A refactoring of the Qualcomm QUP driver which enables new variants to be supported - Explicit support for the Freescale i.MX53 and i.MX6 SPI, Renesas R-Car H3 and Rockchip RV1108 controllers" * tag 'spi-v4.14' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi: (71 commits) spi: spi-falcon: drop check of boot select spi: imx: fix use of native chip-selects with devicetree spi: pl022: constify amba_id spi: imx: fix little-endian build spi: omap: Allocate bus number from spi framework spi: Kernel coding style fixes spi: imx: dynamic burst length adjust for PIO mode spi: Pick spi bus number from Linux idr or spi alias spi: rockchip: configure CTRLR1 according to size and data frame spi: altera: Consolidate TX/RX data register access spi: altera: Switch to SPI core transfer queue management spi: rockchip: add compatible string for rv1108 spi spi: qup: fix 64-bit build warning spi: qup: hide warning for uninitialized variable spi: spi-ep93xx: use the default master transfer queueing mechanism spi: spi-ep93xx: remove private data 'current_msg' spi: spi-ep93xx: pass the spi_master pointer around spi: spi-ep93xx: absorb the interrupt enable/disable helpers spi: spi-ep93xx: add spi master prepare_transfer_hardware() spi: spi-ep93xx: use 32-bit read/write for all registers ... |

Driver core update for 4.14-rc1
Here is the "big" driver core update for 4.14-rc1. It's really not all that big, the largest thing here being some firmware tests to help ensure that that crazy api is working properly. There's also a new uevent for when a driver is bound or unbound from a device, fixing a hole in the driver model that's been there since the very beginning. Many thanks to Dmitry for being persistent and pointing out how wrong I was about this all along :) Patches for the new uevents are already in the systemd tree, if people want to play around with them. Otherwise just a number of other small api changes and updates here, nothing major. All of these patches have been in linux-next for a while with no reported issues.

Many thanks to Dmitry for being persistent and pointing out how wrong I was about this all along :) Patches for the new uevents are already in the systemd tree, if people want to play around with them. Otherwise just a number of other small api changes and updates here, nothing major.

Staging/IIO driver updates for 4.14-rc1
Here is the big staging and IIO driver update for 4.14-rc1. Lots of staging driver fixes and cleanups, including some reorginizing of the lustre header files to try to impose some sanity on what is, and what is not, the uapi for that filesystem. There are some tty core changes in here as well, as the speakup drivers need them, and that's ok with me, they are sane and the speakup code is getting nicer because of it. There is also the addition of the obiligatory new wifi driver, just because it has been a release or two since we added our last one... Other than that, lots and lots of small coding style fixes, as usual. All of these have been in linux-next for a while with no reported issues.

USB/PHY driver updates for 4.14-rc1
Here is the large USB and PHY driver update for 4.14-rc1. Not all that exciting, a few new PHY drivers, the usual mess of gadget driver updates and fixes, and of course, xhci updates to try to tame that beast. A number of usb-serial updates and other small fixes all over the USB driver tree are in here as well. Full details are in the shortlog.
