We do not support out-of-tree building of rpm-pkg / deb-pkg. If O= is given, the build should be terminated, but the "false" command is not effective since it is not the last command in the cmd_src_tar. Then, rpm-pkg / deb-pkg tries to continue building, and fails for a different reason. Set -e option so that the "false" terminates the building immediately. I also put the error messages to stderr, and made it stand out more. For example, "make O=foo rpm-pkg" will fail as follows: /bin/bash ../scripts/package/mkspec >./kernel.spec TAR kernel-4.15.0_rc2+.tar.gz ERROR: Building source tarball is not possible outside the kernel source tree. Don't set KBUILD_OUTPUT, or use the binrpm-pkg or bindeb-pkg target instead. ../scripts/package/Makefile:53: recipe for target 'rpm-pkg' failed Signed-off-by: NMasahiro Yamada <yamada.masahiro@socionext.com> Tested-by: NJim Davis <jim.epost@gmail.com>

Following in footsteps of other targets like 'deb-pkg, 'rpm-pkg' and 'tar-pkg', this patch adds a 'snap-pkg' target for the creation of a Linux kernel snap package using the kbuild infrastructure. A snap, in its general form, is a self contained, sandboxed, universal package and it is intended to work across multiple distributions and/or devices. A snap package is distributed as a single compressed squashfs filesystem. A kernel snap is a snap package carrying the Linux kernel, kernel modules, accessory files (DTBs, System.map, etc) and a manifesto file. The purpose of a kernel snap is to carry the Linux kernel during the creation of a system image, eg. Ubuntu Core, and its subsequent upgrades.

由 Dave Martin 提交于
The fpsimd_update_current_state() function is responsible for loading the FPSIMD state from the user signal frame into the current task during sigreturn. When implementing support for SVE, conditional code was added to this function in order to handle the case where SVE state need to be loaded for the task and merged with the FPSIMD data from the signal frame; however, the FPSIMD-only case was unintentionally dropped. As a result of this, sigreturn does not currently restore the FPSIMD state of the task, except in the case where the system supports SVE and the signal frame contains SVE state in addition to FPSIMD state. This patch fixes this bug by making the copy-in of the FPSIMD data from the signal frame to thread_struct unconditional. This remains a performance regression from v4.14, since the FPSIMD state is now copied into thread_struct and then loaded back, instead of _only_ being loaded into the CPU FPSIMD registers. However, it is essential to call task_fpsimd_load() here anyway in order to ensure that the SVE enable bit in CPACR_EL1 is set correctly before returning to userspace. This could use some refactoring, but since sigreturn is not a fast path I have kept this patch as a pure fix and left the refactoring for later.

When building the arm64 kernel with both CONFIG_ARM64_MODULE_PLTS and CONFIG_DYNAMIC_FTRACE enabled, the ftrace-mod.o object file is built with the kernel and contains a trampoline that is linked into each module, so that modules can be loaded far away from the kernel and still reach the ftrace entry point in the core kernel with an ordinary relative branch, as is emitted by the compiler instrumentation code dynamic ftrace relies on. In order to be able to build out of tree modules, this object file needs to be included into the linux-headers or linux-devel packages, which is undesirable, as it makes arm64 a special case (although a precedent does exist for 32-bit PPC). Given that the trampoline essentially consists of a PLT entry, let's not bother with a source or object file for it, and simply patch it in whenever the trampoline is being populated, using the existing PLT support routines.

When an AFS inode is allocated by afs_alloc_inode(), the allocated afs_vnode struct isn't necessarily reset from the last time it was used as an inode because the slab constructor is only invoked once when the memory is obtained from the page allocator. This means that information can leak from one inode to the next because we're not calling kmem_cache_zalloc(). Some of the information isn't reset, in particular the permit cache pointer. Bring the clearances up to date. Signed-off-by: NDavid Howells <dhowells@redhat.com> Tested-by: NMarc Dionne <marc.dionne@auristor.com>

Fix four refcount bugs in afs_cache_permit(): (1) When checking the result of the kzalloc(), we can't just return, but must put 'permits'. (2) We shouldn't put permits immediately after hashing a new permit as we need to keep the pointer stable so that we can check to see if vnode->permit_cache has changed before we decide whether to assign to it. (3) 'permits' is being put twice. (4) We need to put either the replacement or the thing replaced after the assignment to vnode->permit_cache. Without this, lots of the following are seen: Kernel BUG at ffffffffa039857b [verbose debug info unavailable] ------------[ cut here ]------------ Kernel BUG at ffffffffa039858a [verbose debug info unavailable] ------------[ cut here ]------------ The addresses are in the .text..refcount section of the kafs.ko module.
