Pull powerpc fixes from Michael Ellerman: "It turns out our single-fix pull from last week was too good to be true. I missed a few fixes in that pull that had already come in because I was on leave, but also we hadn't found the bugs yet. So this week it's a bit bigger, though not ridiculous. Hopefully things will settle down from here on. Four fixes for the new instruction emulation code. A fix for CPU offline on bare metal machines when certain idle states are not supported, and a fix for a device_node refcounting oops during CPU hotplug, caused by recent changes. Going to stable are a fix for an oops during core dump on machines that have TM (Transactional Memory) disabled. Reordering some EEH initialisation to avoid trashing memory, and another device_node refcounting fix. And a few other minor things.

The inline asm in __write_64bit_c0_split() modifies the 64-bit input operand by shifting the high register left by 32, and constructing the full 64-bit value in the low register (even on a 32-bit kernel), so if that value is used again it could cause breakage as GCC would assume the registers haven't changed when they have. To quote the GCC extended asm documentation: > Warning: Do not modify the contents of input-only operands (except for > inputs tied to outputs). The compiler assumes that on exit from the > asm statement these operands contain the same values as they had > before executing the statement. Avoid modifying the input by using a temporary variable as an output which is modified instead of the input and not otherwise used. The asm is always __volatile__ so GCC shouldn't optimise it out. The low register of the temporary output is written before the high register of the input is read, so we have two constraint alternatives, one where both use the same registers (for when the input value isn't subsequently used), and one with an early clobber on the output in case the low output uses the same register as the high input. This allows the resulting assembly to remain mostly unchanged. A diff of a MIPS32r6 kernel reveals only three differences, two in relation to write_c0_r10k_diag() in cpu_probe() (register allocation rearranged slightly but otherwise identical), and one in relation to write_c0_cvmmemctl2() in kvm_vz_local_flush_guesttlb_all(), but the octeon CPU is only supported on 64-bit kernels where __write_64bit_c0_split() isn't used so that shouldn't matter in practice. So there currently doesn't appear to be anything broken by this bug.

Commit 215ee763 ("powerpc: pseries: remove dlpar_attach_node dependency on full path") reworked dlpar_attach_node() to no longer look up the parent node "/cpus", but instead to have the parent node passed by the caller in the function parameter list. As a result dlpar_attach_node() is no longer responsible for freeing the reference to the parent node. However, commit 215ee763 failed to remove the of_node_put(parent) call in dlpar_attach_node(), or to take into account that the reference to the parent in the caller dlpar_cpu_add() needs to be held until after dlpar_attach_node() returns. As a result doing repeated cpu add/remove dlpar operations will eventually result in the following error: OF: ERROR: Bad of_node_put() on /cpus CPU: 0 PID: 10896 Comm: drmgr Not tainted 4.13.0-autotest #1 Call Trace: dump_stack+0x15c/0x1f8 (unreliable) of_node_release+0x1a4/0x1c0 kobject_put+0x1a8/0x310 kobject_del+0xbc/0xf0 __of_detach_node_sysfs+0x144/0x210 of_detach_node+0xf0/0x180 dlpar_detach_node+0xc4/0x120 dlpar_cpu_remove+0x280/0x560 dlpar_cpu_release+0xbc/0x1b0 arch_cpu_release+0x6c/0xb0 cpu_release_store+0xa0/0x100 dev_attr_store+0x68/0xa0 sysfs_kf_write+0xa8/0xf0 kernfs_fop_write+0x2cc/0x400 __vfs_write+0x5c/0x340 vfs_write+0x1a8/0x3d0 SyS_write+0xa8/0x1a0 system_call+0x58/0x6c Fix the issue by removing the of_node_put(parent) call from dlpar_attach_node(), and ensuring that the reference to the parent node is properly held and released by the caller dlpar_cpu_add().

Commit 553f770e ("ipc: move compat shmctl to native") moved the compat IPC syscall handling into ipc/shm.c and refactored the struct accessors in the process. Unfortunately, the call to copy_compat_shmid_to_user when handling a compat {IPC,SHM}_STAT command gets the arguments the wrong way round, passing a kernel stack address as the user buffer (destination) and the user buffer as the kernel stack address (source). This patch fixes the parameter ordering so the buffers are accessed correctly.

The "Release:" field of the spec file is determined based on the .version file. However, the .version file is not copied to the source tar file. So, when we build the kernel from the source package, the UTS_VERSION always indicates #1. This does not match with "rpm -q". The kernel UTS_VERSION and "rpm -q" do not agree for binrpm-pkg, either. Please note the kernel has already been built before the spec file is created. Currently, mkspec invokes mkversion. This script returns an incremented version. So, the "Release:" field of the spec file is greater than the version in the kernel by one. For the source package build (where .version file is missing), we can give KBUILD_BUILD_VERSION=%{release} to the build command. For the binary package build, we can simply read out the .version file because it contains the version number that was used for building the kernel image. We can remove scripts/mkversion because scripts/package/Makefile need not touch the .version file. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>

If running on machines that do not provide topology information we currently generate a "fake" topology which defines the maximum distance between each cpu: each cpu will be put into an own drawer. Historically this used to be the best option for (virtual) machines in overcommited hypervisors. For some workloads however it is better to generate a different topology where all cpus are siblings within a package (all cpus are core siblings). This shows performance improvements of up to 10%, depending on the workload. In order to keep the current behaviour, but also allow to switch to the different core sibling topology use the existing "topology=" kernel parameter: Specifying "topology=on" on machines without topology information will generate the core siblings (fake) topology information, instead of the default topology information where all cpus have the maximum distance. On machines which provide topology information specifying "topology=on" does not have any effect.

Optprobes depended on an updated regs->nip from analyse_instr() to identify the location to branch back from the optprobes trampoline. However, since commit 3cdfcbfd ("powerpc: Change analyse_instr so it doesn't modify *regs"), analyse_instr() doesn't update the registers anymore. Due to this, we end up branching back from the optprobes trampoline to the same branch into the trampoline resulting in a loop. Fix this by calling out to emulate_update_regs() before using the nip. Additionally, explicitly compare the return value from analyse_instr() to 1, rather than just checking for !0 so as to guard against any future changes to analyse_instr() that may result in -1 being returned in more scenarios.

Today, md5sum fails with error -ENOKEY because a setkey function is set for non hmac hashing algs, see strace output below: mmap(NULL, 378880, PROT_READ, MAP_SHARED, 6, 0) = 0x77f50000 accept(3, 0, NULL) = 7 vmsplice(5, [{"bin/\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0"..., 378880}], 1, SPLICE_F_MORE|SPLICE_F_GIFT) = 262144 splice(4, NULL, 7, NULL, 262144, SPLICE_F_MORE) = -1 ENOKEY (Required key not available) write(2, "Generation of hash for file kcap"..., 50) = 50 munmap(0x77f50000, 378880) = 0 This patch ensures that setkey() function is set only for hmac hashing.
