f0bc4ed1 - kinst: Initial revision

Tue, 11 Oct 2022 15:28:17 +0000

kinst: Initial revisionThis is a new DTrace provider which allows arbitrary kernel instructionsto be traced. Currently it is implemented only for amd64.kinst probes are created on demand by libdtrace, and there is a probefor each kernel instruction. Probes are namedkinst:::, where "offset" is the offset of thetarget instruction relative to the beginning of the function. Omitting"offset" causes all instructions in the function to be traced.kinst works similarly to FBT in that it places a breakpoint on thetarget instruction and hooks into the kernel breakpoint handler.Because kinst has to be able to trace arbitrary instructions, it doesnot emulate most of them in software but rather causes the traced threadto execute a copy of the instruction before returning to the originalcode.The provider is quite low-level and as-is will be useful mostly only tokernel developers. However, it provides a great deal of visibility intokernel code execution and could be used as a building block forhigher-level tooling which can in some sense translate between C sourcesand generated machine code. In particular, the "regs" variable recentlyadded to D allows the CPU's register file to be accessed from kinstprobes.kinst is experimental and should not be used on production systems fornow.In collaboration with: markjSponsored by: Google, Inc.

efe88d92 - Disconnect fasttrap from the 32-bit powerpc build.

Thu, 21 Feb 2019 22:49:21 +0000

Disconnect fasttrap from the 32-bit powerpc build.An upcoming bug fix requires 64-bit atomics, which aren't implemented onpowerpc. The powerpc port of fasttrap is incomplete anyway and doesn'tget loaded by dtraceall.ko on powerpc because of a missing dependency;it's presumed that it's effectively unused.Discussed with: jhibbitsMFC after: 2 weeks List of files: /freebsd-14.2/sys/modules/dtrace/Makefile

Wed, 29 Mar 2017 19:58:00 +0000

Add an experimental DTrace audit provider, which allows users of DTrace toinstrument security event auditing rather than relying on conventional BSMtrail 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 supportfuture mechanisms of instrumenting multiple events via a single probe --e.g., using classes), a pointer to the in-kernel audit record, and anoptional pointer to the BSM data and its length. For human convenience,upper-case audit event names (AUE_...) are converted to lower case inDTrace.DTrace scripts can now cause additional audit-based data to be collectedon system calls, and inspect internal and BSM representations of the data.They do not affect data captured in the audit trail or audit pipesconfigured in the system. auditd(8) must be configured and running inorder to provide a database of event information, as well as other auditconfiguration parameters (e.g., to capture command-line arguments orenvironmental variables) for the provider to operate.Reviewed by: gnn, jonathan, markjSponsored by: DARPA, AFRLMFC after: 3 weeksDifferential Revision: https://reviews.freebsd.org/D10149 List of files: /freebsd-14.2/sys/modules/dtrace/Makefile

Rename remaining linux32 symbols such as linux_sysent[] andlinux_syscallnames[] from linux_* to linux32_* to avoid conflicts withlinux64.ko. While here, add support for linux64 binaries to systrace.- Update NOPROTO entries in amd64/linux/syscalls.master to match the main table to fix systrace build.- Add a special case for union l_semun arguments to the systrace generation.- The systrace_linux32 module now only builds the systrace_linux32.ko. module on amd64.- Add a new systrace_linux module that builds on both i386 and amd64. For i386 it builds the existing systrace_linux.ko. For amd64 it builds a systrace_linux.ko for 64-bit binaries.Reviewed by: markjDifferential Revision: https://reviews.freebsd.org/D3954 List of files: /freebsd-14.2/sys/modules/dtrace/Makefile
