2018-03-03Remove more references to ptrace_pt_{g,s}et_sigmaskKamil Rytarowski
These operations are now obsolete on NetBSD and will be removed. No functional change for other OSes. Sponsored by <The NetBSD Foundation> git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@326663 91177308-0d34-0410-b5e6-96231b3b80d8
2018-03-03Remove obsolete ptrace(2) operations from NetBSDKamil Rytarowski
PT_SET_SIGMASK and PT_GET_SIGMASK will be removed from NetBSD without backward compat (it shortlived in a development branch). Sponsored by <The NetBSD Foundation> git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@326657 91177308-0d34-0410-b5e6-96231b3b80d8
2018-02-26Skip two more ioctl interceptors for NetBSDKamil Rytarowski
Don't intercept: - HFSC_IF_ATTACH - HFSC_MOD_CLASS These operations conflict on NetBSD 32-bit with: - PRIQ_IF_ATTACH - PRIQ_MOD_CLASS Sponsored by <The NetBSD Foundation> git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@326084 91177308-0d34-0410-b5e6-96231b3b80d8
2018-02-15Implement a large part of NetBSD syscalls of netbsd_syscall_hooks.hKamil Rytarowski
This is a follow up of: r325206 - Add NetBSD syscall hooks skeleton in sanitizers Sponsored by <The NetBSD Foundation> git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@325248 91177308-0d34-0410-b5e6-96231b3b80d8
2018-02-15Teach sanitizer about NetBSD specific ioctl(2) callsKamil Rytarowski
Summary: Introduce handling of 1200 NetBSD specific ioctl(2) calls. Over 100 operations are disabled as unavailable or conflicting with the existing ones (the same operation number). Add a script that generates the rules to detect ioctls on NetBSD. The generate_netbsd_ioctls.awk script has been written in NetBSD awk(1) (patched nawk) and is compatible with gawk. Generate lib/sanitizer_common/sanitizer_interceptors_ioctl_netbsd.inc with the awk(1) script. Update sanitizer_platform_limits_netbsd accordingly to add the needed definitions.

2018-02-15Add NetBSD syscall hooks skeleton in sanitizersKamil Rytarowski
Summary: Implement the skeleton of NetBSD syscall hooks for use with sanitizers. Add a script that generates the rules to handle syscalls on NetBSD: generate_netbsd_syscalls.awk. It has been written in NetBSD awk(1) (patched nawk) and is compatible with gawk. Generate lib/sanitizer_common/sanitizer_platform_limits_netbsd.h that is a public header for applications, and included as: <sanitizer_common/sanitizer_platform_limits_netbsd.h>. Generate sanitizer_syscalls_netbsd.inc that defines all the syscall rules for NetBSD. This file is modeled after the Linux specific file: sanitizer_common_syscalls.inc. Start recognizing NetBSD syscalls with existing sanitizers: ASan, ESan, HWASan, TSan, MSan.
