blackfin: Use get_signal() signal_setup_done()

2019-05-02T20:41:41+00:00

commit 1270cff147a39f7da5b25225dca6ca3132ca6130 upstream. Use the more generic functions get_signal() signal_setup_done() for signal delivery.

Make asm/word-at-a-time.h available on all architectures

2018-10-21T07:46:11+00:00

commit a6e2f029ae34f41adb6ae3812c32c5d326e1abd2 upstream. Added the x86 implementation of word-at-a-time to the generic version, which previously only supported big-endian. Omitted the x86-specific load_unaligned_zeropad(), which in any case is also not present for the existing BE-only implementation of a word-at-a-time, and is only used under CONFIG_DCACHE_WORD_ACCESS. Added as a "generic-y" to the Kbuilds of all architectures that didn't previously have it.

commit 2bc6ff14d46745a7728ed4ed90c5e0edca91f52e upstream. We've replaced remap_file_pages(2) implementation with emulation. Nobody creates non-linear mapping anymore. Signed-off-by: Kirill A.

ptrace: Don't allow accessing an undumpable mm

2018-01-01T20:52:11+00:00

commit 84d77d3f06e7e8dea057d10e8ec77ad71f721be3 upstream. It is the reasonable expectation that if an executable file is not readable there will be no way for a user without special privileges to read the file. This is enforced in ptrace_attach but if ptrace is already attached before exec there is no enforcement for read-only executables. As the only way to read such an mm is through access_process_vm spin a variant called ptrace_access_vm that will fail if the target process is not being ptraced by the current process, or the current process did not have sufficient privileges when ptracing began to read the target processes mm. In the ptrace implementations replace access_process_vm by ptrace_access_vm. There remain several ptrace sites that still use access_process_vm as they are reading the target executables instructions (for kernel consumption) or register stacks. As such it does not appear necessary to add a permission check to those calls. This bug has always existed in Linux. Fixes: v1.0 Reported-by: Andy Lutomirski Signed-off-by: "Eric W.
