SVN rev 215679 on 2010-11-22 14:42:13Z by attilio Add the ability for GDB to printout the thread name along with other thread specific informations. In order to do that, and in order to avoid KBI breakage with existing infrastructure the following semantic is implemented: - For live programs, a new member to the PT_LWPINFO is added (pl_tdname) - For cores, a new ELF note is added (NT_THRMISC) that can be used for storing thread specific, miscellaneous, informations. Right now it is just popluated with a thread name. GDB, then, retrieves the correct informations from the corefile via the BFD interface, as it groks the ELF notes and create appropriate pseudo-sections.

The i386, amd64, sparc64, sun4v, powerpc and ia64 syscall()s are changed to use syscallenter()/syscallret(). MIPS and arm are not converted and use the mostly unchanged syscall() implementation. MFC r208514: Change ia64' struct syscall_args definition so that args is a pointer to the arguments array instead of array itself. MFC r208566: Allow to use syscallname(9) outside subr_trap.c. MFC r209258 (by rpaulo): Make DTrace syscall provider work again by including opt_kdtrace.h here. MFC r209313: Only enable kdtrace hook in the LINT on the architectures that implement it. MFC r209697: Obey sv_syscallnames bounds in syscallname(). NOTE: The KBI of the struct sysentvec is changed, new required members sv_set_syscall_retval, sv_fetch_syscall_args and sv_syscallnames are added. The sv_prepsyscall field is now ignored. Third-party modules using the struct sysentvec must be modified and recompiled, we believe that only ABI emulators are affected. No such out-of-tree modules are known. In-tree modules that are affected by the change were converted to depend on exact version of the kernel, see r214421.

SVN rev 208453 on 2010-05-23 18:32:02Z by kib Reorganize syscall entry and leave handling. Extend struct sysvec with three new elements: sv_fetch_syscall_args - the method to fetch syscall arguments from usermode into struct syscall_args. The structure is machine-depended (this might be reconsidered after all architectures are converted). sv_set_syscall_retval - the method to set a return value for usermode from the syscall. It is a generalization of cpu_set_syscall_retval(9) to allow ABIs to override the way to set a return value. sv_syscallnames - the table of syscall names. Use sv_set_syscall_retval in kern_sigsuspend() instead of hardcoding the call to cpu_set_syscall_retval(). The new functions syscallenter(9) and syscallret(9) are provided that use sv_*syscall* pointers and contain the common repeated code from the syscall() implementations for the architecture-specific syscall trap handlers. Syscallenter() fetches arguments, calls syscall implementation from ABI sysent table, and set up return frame. The end of syscall bookkeeping is done by syscallret(). Take advantage of single place for MI syscall handling code and implement ptrace_lwpinfo pl_flags PL_FLAG_SCE, PL_FLAG_SCX and PL_FLAG_EXEC. The SCE and SCX flags notify the debugger that the thread is stopped at syscall entry or return point respectively. The EXEC flag augments SCX and notifies debugger that the process address space was changed by one of exec(2)-family syscalls. The i386, amd64, sparc64, sun4v, powerpc and ia64 syscall()s are changed to use syscallenter()/syscallret(). MIPS and arm are not converted and use the mostly unchanged syscall() implementation.

Jumbo-commit to enhance 32 bit application support on 64 bit kernels. This is good enough to be able to run a RELENG_4 gdb binary against a RELENG_4 application, along with various other tools (eg: 4.x gcore). We use this at work. ia32_reg.[ch]: handle the 32 bit register file format, used by ptrace, procfs and core dumps. procfs_*regs.c: vary the format of proc/XXX/*regs depending on the client and target application. procfs_map.c: Don't print a 64 bit value to 32 bit consumers, or their sscanf fails. They expect an unsigned long. imgact_elf.c: produce a valid 32 bit coredump for 32 bit apps. sys_process.c: handle 32 bit consumers debugging 32 bit targets. Note that 64 bit consumers can still debug 32 bit targets. IA64 has got stubs for ia32_reg.c. Known limitations: a 5.x/6.x gdb uses get/setcontext(), which isn't implemented in the 32/64 wrapper yet. We also make a tiny patch to gdb pacify it over conflicting formats of ld-elf.so.1. Approved by: re

Implement the PT_LWPINFO request. This request can be used by the
tracing process to obtain information about the LWP that caused the
traced process to stop. Debuggers can use this information to select
the thread currently running on the LWP as the current thread.
The request has been made compatible with NetBSD for as much as
possible. This implementation differs from NetBSD in the following
ways:
1. The data argument is allowed to be smaller than the size of the
ptrace_lwpinfo structure known to the kernel, but not 0. This
is opposite to what NetBSD allows. The reason for this is that
we can extend the structure without affecting older binaries.
2. On NetBSD the tracing process is to set the pl_lwpid field to
the Id of the LWP it wants information of. We don't do that.
Our ptrace interface allows passing the LWP Id instead of the
PID. The tracing process is to set the PID to the LWP Id it
wants information of.
3. When the PID is actually the PID of the tracing process, this
request returns the information about the LWP that caused the
process to stop. This was the whole purpose of the request in
the first place.
When the traced process has exited, this request will return the
LWP Id 0, indicating that the process state is not the result of
an event specific to a LWP.

Add or finish support for machine dependent ptrace requests. When we check for permissions, do it for all requests, not the known requests. Later when we actually service the request we deal with the invalid requests we previously caught earlier. This commit changes the behaviour of the ptrace(2) interface for boundary cases such as an unknown request without proper permissions. Previously we would return EINVAL. Now we return EBUSY or EPERM. Platforms need to define __HAVE_PTRACE_MACHDEP when they have MD requests. This makes the prototype of cpu_ptrace() visible and introduces a call to this function for all requests greater or equal to PT_FIRSTMACH. Silence on: audit

Dissociate ptrace from procfs.
Until now, the ptrace syscall was implemented as a wrapper that called
various functions in procfs depending on which ptrace operation was
requested. Most of these functions were themselves wrappers around
procfs_{read,write}_{,db,fp}regs(), with only some extra error checks,
which weren't necessary in the ptrace case anyway.
This commit moves procfs_rwmem() from procfs_mem.c into sys_process.c
(renaming it to proc_rwmem() in the process), and implements ptrace()
directly in terms of procfs_{read,write}_{,db,fp}regs() instead of
having it fake up a struct uio and then call procfs_do{,db,fp}regs().
It also moves the prototypes for procfs_{read,write}_{,db,fp}regs()
and proc_rwmem() from proc.h to ptrace.h, and marks all procfs files
except procfs_machdep.c as "optional procfs" instead of "standard".

Zap 'ptrace(PT_READ_U, ...)' and 'ptrace(PT_WRITE_U, ...)' since they are a really nasty interface that should have been killed long ago when 'ptrace(PT_[SG]ETREGS' etc came along. The entity that they operate on (struct user) will not be around much longer since it is part-per-process and part-per-thread in a post-KSE world. gdb does not actually use this except for the obscure 'info udot' command which does a hexdump of as much of the child's 'struct user' as it can get. It carries its own #defines so it doesn't break compiles.

This commit fixes various 64bit portability problems required for FreeBSD/alpha. The most significant item is to change the command argument to ioctl functions from int to u_long. This change brings us inline with various other BSD versions. Driver writers may like to use (__FreeBSD_version == 300003) to detect this change. The prototype FreeBSD/alpha machdep will follow in a couple of days time.
