* Move most of the contents of opt_compat.h to opt_global.h.Brooks Davis2018-04-064-11/+3
| | | | | | | | | | | | | | | | | | | | | opt_compat.h is mentioned in nearly 180 files. In-progress network driver compabibility improvements may add over 100 more so this is closer to "just about everywhere" than "only some files" per the guidance in sys/conf/options. Keep COMPAT_LINUX32 in opt_compat.h as it is confined to a subset of sys/compat/linux/*.c. A fake _COMPAT_LINUX option ensure opt_compat.h is created on all architectures. Move COMPAT_LINUXKPI to opt_dontuse.h as it is only used to control the set of compiled files.

* sys: general adoption of SPDX licensing ID tags.Pedro F. Giffuni2017-11-271-1/+3
| | | | | | | | | | | | | | | | | Mainly focus on files that use BSD 2-Clause license, however the tool I was using misidentified many licenses so this was mostly a manual - error prone - task. The Software Package Data Exchange (SPDX) group provides a specification to make it easier for automated tools to detect and summarize well known opensource licenses. We are gradually adopting the specification, noting that the tags are considered only advisory and do not, in any way, superceed or replace the license texts. No functional change intended.

* Stop building assym.o into the module.Bryan Drewery2017-04-051-15/+1
| | | | | | | | | | | | | | | | | | DTrace includes assym.s, to build this we build assym.o, however this is unneeded as assym.s only contains macros. Remove the need to build this by removing it from OBJS, but keep assym.s in the module dependencies via DPSRCS. This fixes the build when there is no assembler, e.g. on arm64 without the external binutils.

* Add an experimental DTrace audit provider, which allows users of DTrace toRobert Watson2017-03-292-1/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | instrument security event auditing rather than relying on conventional BSM trail files or audit pipes: - Add a set of per-event 'commit' probes, which provide access to particular auditable events at the time of commit in system-call return. These probes gain access to audit data via the in-kernel audit_record data structure, providing convenient access to system-call arguments and return values in a single probe. - Add a set of per-event 'bsm' probes, which provide access to particular auditable events at the time of BSM record generation in the audit worker thread. These probes have access to the in-kernel audit_record data structure and BSM representation as would be written to a trail file or audit pipe -- i.e., asynchronously in the audit worker thread. DTrace probe arguments consist of the name of the audit event (to support future mechanisms of instrumenting multiple events via a single probe -- e.g., using classes), a pointer to the in-kernel audit record, and an optional pointer to the BSM data and its length. For human convenience, upper-case audit event names (AUE_...) are converted to lower case in DTrace. DTrace scripts can now cause additional audit-based data to be collected on system calls, and inspect internal and BSM representations of the data. They do not affect data captured in the audit trail or audit pipes configured in the system. auditd(8) must be configured and running in order to provide a database of event information, as well as other audit configuration parameters (e.g., to capture command-line arguments or environmental variables) for the provider to operate.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | option, unbreak the lock tracing release semantic by embedding calls to LOCKSTAT_PROFILE_RELEASE_LOCK() direclty in the inlined version of the releasing functions for mutex, rwlock and sxlock. Failing to do so skips the lockstat_probe_func invokation for unlocking. - As part of the LOCKSTAT support is inlined in mutex operation, for kernel compiled without lock debugging options, potentially every consumer must be compiled including opt_kdtrace.h. Fix this by moving KDTRACE_HOOKS into opt_global.h and remove the dependency by opt_kdtrace.h for all files, as now only KDTRACE_FRAMES is linked there and it is only used as a compile-time stub [0]. [0] immediately shows some new bug as DTRACE-derived support for debug in sfxge is broken and it was never really tested. As it was not including correctly opt_kdtrace.h before it was never enabled so it was kept broken for a while. Fix this by using a protection stub, leaving sfxge driver authors the responsibility for fixing it appropriately [1].
