d152fc3170 Document TRAP_EXEC in SIGRAP in siginfo(2)

This signal is emitted on exec() when a process is controlled by a
debugger.

ba2267e1eb Welcome to 7.99.56 for new ptrace(2) interfaces and SIGTRAP type TRAP_EXEC 
Kernel bump for PT_GET_SIGINFO and PT_SET_SIGINFO in ptrace(2) and new
si_code value TRAP_EXEC in <sys/siginfo.h> for the SIGTRAP signal.

e4281b2073 Introduce new ptrace(2) interface: PT_SET_SIGINFO and PT_GET_SIGINFO 
This interface is designed to read signal information emited to tracee and
fake this signal with new value.

This functionality is required to distinguish types of events that occured
in the tracee and intercepted by a debugger.

These accessors introduce a new structure type ptrace_siginfo:
/*
 * Signal Information structure
 */
typedef struct ptrace_siginfo {
       siginfo_t       psi_siginfo;    /* signal information structure */
       lwpid_t         psi_lwpid;      /* destination LWP of the signal
                                        * value 0 means the whole process
                                        * (route signal to all LWPs) */
} ptrace_siginfo_t;

Include <sys/siginfo.h> in <sys/ptrace.h> in order to not break existing
software due to unknown symbol siginfo_t.

This interface has been proposed to the tech-kern@ mailing list.

239e90be56 Introduce new SIGTRAP code: TRAP_EXEC 
On exec() events under a debugger generate the SIGTRAP signal with
TRAP_EXEC property. This allows tracer to distinguish exec() events easily.

5b0bbc1439 Add new test siginfo4 in t_ptrace_wait{,3,4,6,id,pid} 
siginfo4:
    Detect SIGTRAP TRAP_EXEC from tracee

This test is currently disabled and it will be enabled once
PT_[SG]ET_SIGINFO will land the sources.

d020b0ddde Implement a common spkr_detach() function and call it from the 
attachment-specific detach functions.  Returns EBUSY if the
device instance is busy, based on whether or not a sc->sc_inbuf
is allocated.  The buffer is malloc()d at spkropen time, and is
free()d in spkrclose().

Now we can actually implement the MODULE_CMD_FINI command and
unload the driver at will.

7f64160e7f The inline functions {ms,us,ns}2bintime() are currently defined\nincorrectly, and always result in the bt.frac being set to zero.\nEven correcting for left- vs right shifts, the results are low\nprecision with at most 32 significant bits.\n\nRewrite using 64-bit multiply rather than division to get proper\nresults. Also the multiply is less costly than a divide on most\nplatforms. 2017-01-05 22:51:15 +00:00
