/* Machine independent support for SVR4 /proc (process file system) for GDB.
* buildsym.c (finish_block): Fix thinko `inner block' complaints. * dbxread.c (process_one_symbol): Parse N_OPT "gcc2_compiled.". * procfs.c (proc_set_exec_trap): Set run-on-last-close flag on child processes, to avoid dead ones "hanging around" after GDB exits. (attach): Always stop the process if it needs it. Set RLC flag when attaching running processes, so it will continue if we detach it, quit, or are killed. (detach): Clear faults and set RLC flag to make process run when we close it. (open_proc_file): New `mode' argument for O_RDONLY or O_RDWR. Callers changed. (info_proc): Open process O_RDONLY, so we can see any process, even those controlled by debuggers. * tm-sun4sol2.h (SUN_FIXED_LBRAC_BUG): They did (in Sol 2).

defined, then support for the floating point register set is desired,

When gdb is configured to use /proc, it should not be calling

where use of /proc is configured, but some routine is still calling
ptrace, we provide a local version of a function with that name
that does nothing but issue an error message.

DESCRIPTION
Store our current register values back into the inferior. If
REGNO is -1 then store all the register, otherwise store just
the value specified by REGNO.
NOTES
If we are storing only a single register, we first have to get all
the current values from the process, overwrite the desired register
in the gregset with the one we want from gdb's registers, and then
send the whole set back to the process. For writing all the
registers, all we have to do is generate the gregset and send it to
the process.
Also note that the process has to be stopped on an event of interest
for this to work, which basically means that it has to have been
run under the control of one of the other /proc ioctl calls and not
ptrace. Since we don't use ptrace anyway, we don't worry about this
fine point, but it is worth noting for future reference.
Gdb is confused about what this function is supposed to return.
Some versions return a value, others return nothing. Some are
declared to return a value and actually return nothing. Gdb ignores
anything returned. (FIXME)

DESCRIPTION
When gdb starts an inferior, this function is called in the parent
process immediately after the fork. It waits for the child to stop
on the return from the exec system call (the child itself takes care
of ensuring that this is set up), then sets up the set of signals
and faults that are to be traced.
NOTES
If proc_init_failed ever gets called, control returns to the command
processing loop via the standard error handling code.

DESCRIPTION
When the user changes the state of gdb's signal handling via the
"handle" command, this function gets called to see if any change
in the /proc interface is required. It is also called internally
by other /proc interface functions to initialize the state of
the traced signal set.
One thing it does is that signals for which the state is "nostop",
"noprint", and "pass", have their trace bits reset in the pr_trace
field, so that they are no longer traced. This allows them to be
delivered directly to the inferior without the debugger ever being
involved.

proc_set_exec_trap -- arrange for exec'd child to halt at startup
SYNOPSIS
void proc_set_exec_trap (void)
DESCRIPTION
This function is called in the child process when starting up
an inferior, prior to doing the exec of the actual inferior.
It sets the child process's exitset to make exit from the exec
system call an event of interest to stop on, and then simply
returns. The child does the exec, the system call returns, and
the child stops at the first instruction, ready for the gdb
parent process to take control of it.
NOTE
We need to use all local variables since the child may be sharing
it's data space with the parent, if vfork was used rather than
fork.
Many changes to procfs.c, mostly to expand the "info proc" command and to fix a couple of small bugs. Changes to other files mostly to fix minor things pointed out by the SGI compiler. See ChangeLog for complete details.
1992-04-02 03:46:14 +08:00
Also note that we want to turn off the inherit-on-fork flag in
the child process so that any grand-children start with all
tracing flags cleared.

DESCRIPTION
Given an address in the current inferior's address space, use the
/proc interface to find an open file descriptor for the file that
this address was mapped in from. Return -1 if there is no current
inferior. Print a warning message if there is an inferior but
the address corresponds to no file (IE a bogus address).

DESCRIPTION
Attach to an already existing process with the specified process
id. If the process is not already stopped, query whether to
stop it or not.
NOTES
The option of stopping at attach time is specific to the /proc
versions of gdb. Versions using ptrace force the attachee
* buildsym.c (finish_block): Fix thinko `inner block' complaints. * dbxread.c (process_one_symbol): Parse N_OPT "gcc2_compiled.". * procfs.c (proc_set_exec_trap): Set run-on-last-close flag on child processes, to avoid dead ones "hanging around" after GDB exits. (attach): Always stop the process if it needs it. Set RLC flag when attaching running processes, so it will continue if we detach it, quit, or are killed. (detach): Clear faults and set RLC flag to make process run when we close it. (open_proc_file): New `mode' argument for O_RDONLY or O_RDWR. Callers changed. (info_proc): Open process O_RDONLY, so we can see any process, even those controlled by debuggers. * tm-sun4sol2.h (SUN_FIXED_LBRAC_BUG): They did (in Sol 2).

DESCRIPTION
Detach from the current attachee.
If signal is non-zero, the attachee is started running again and sent
the specified signal.
If signal is zero and the attachee was not already stopped when we
attached to it, then we make it runnable again when we detach.
Otherwise, we query whether or not to make the attachee runnable
again, since we may simply want to leave it in the state it was in
when we attached.
We report any problems, but do not consider them errors, since we
MUST detach even if some things don't seem to go right. This may not
be the ideal situation. (FIXME).

DESCRIPTION
Try to emulate wait() as much as possible. Not sure why we can't
just use wait(), but it seems to have problems when applied to a
process being controlled with the /proc interface.
NOTES
We have a race problem here with no obvious solution. We need to let
the inferior run until it stops on an event of interest, which means
that we need to use the PIOCWSTOP ioctl. However, we cannot use this
ioctl if the process is already stopped on something that is not an
event of interest, or the call will hang indefinitely. Thus we first
use PIOCSTATUS to see if the process is not stopped. If not, then we
use PIOCWSTOP. But during the window between the two, if the process
stops for any reason that is not an event of interest (such as a job
control signal) then gdb will hang. One possible workaround is to set
an alarm to wake up every minute of so and check to see if the process
is still running, and if so, then reissue the PIOCWSTOP. But this is
a real kludge, so has not been implemented. FIXME: investigate
alternatives.
FIXME: Investigate why wait() seems to have problems with programs
being control by /proc routines.
*/
Make the /proc support a target-struct in its own right. * inferior.h (proc_wait, inferior_proc_init, proc_set_exec_trap): No longer global functions. (fork_inferior): New global function from fork-child.c. * inftarg.c (child_wait): Remove USE_PROC_FS conditional. (ptrace_me, ptrace_him): New stub functions for fork_inferior(). (child_create_inferior): Moved to fork-child.c as fork_inferior. (child_create_inferior): New tiny function that calls fork_inferior. * fork-child.c: New file, containing fork_inferior, which is built from slight mods to inftarg.c's child_create_inferior. * procfs.c (procfs_ops): Add target vector. (attach): Rename as static do_attach. (procfs_create_inferior): New tiny function that calls fork_inferior. (child_xfer_memory): Rename to static procfs_xfer_memory. (store_inferior_registers): Rename to static procfs_store_registers. (inferior_proc_init): Rename to static procfs_init_inferior. (procfs_attach, procfs_detach, procfs_prepare_to_store, procfs_files_info, procfs_open, procfs_mourn_inferior, procfs_can_run): Slightly mangled copies of the corresponding child_XXX routines from inftarg.c. (proc_wait): Renamed to static procfs_wait. (child_resume): Rename to static procfs_resume. (fetch_inferior_registers): Rename to static procfs_fetch_registers. (initialize_proc_fs): Rename to initialize_procfs. Set up procfs_ops, too. * xm-irix4.h, xm-sysv4.h (CREATE_INFERIOR_HOOK): No longer needed.

LOCAL FUNCTION
set_proc_siginfo - set a process's current signal info
SYNOPSIS
void set_proc_siginfo (struct procinfo *pip, int signo);
DESCRIPTION
Given a pointer to a process info struct in PIP and a signal number
in SIGNO, set the process's current signal and its associated signal
information. The signal will be delivered to the process immediately
after execution is resumed, even if it is being held. In addition,
this particular delivery will not cause another PR_SIGNALLED stop
even if the signal is being traced.
If we are not delivering the same signal that the prstatus siginfo
struct contains information about, then synthesize a siginfo struct
to match the signal we are doing to deliver, make it of the type
"generated by a user process", and send this synthesized copy. When
used to set the inferior's signal state, this will be required if we
are not currently stopped because of a traced signal, or if we decide
to continue with a different signal.
Note that when continuing the inferior from a stop due to receipt
of a traced signal, we either have set PRCSIG to clear the existing
signal, or we have to call this function to do a PIOCSSIG with either
the existing siginfo struct from pr_info, or one we have synthesized
appropriately for the signal we want to deliver. Otherwise if the
signal is still being traced, the inferior will immediately stop
again.
See siginfo(5) for more details.

Many small changes to procfs.c to add base support for a new "info proc" command that prints /proc specific information, changes to solib.c to allow more flexible handling of finding the dynamic linker structures, changes to utils.c and defs.h to add a new null_cleanup() function to serve as an anchor point for cleanup chains with no obvious "first cleanup".

Given a process id and a mode, close the existing open /proc
entry (if any) and open one for the new process id, in the
specified mode. Once it is open, then mark the local process
information structure as valid, which guarantees that the pid,
fd, and pathname fields match an open /proc entry. Returns
zero if the open fails, nonzero otherwise.

Note that the pathname is left intact, even when the open fails,
so that callers can use it to construct meaningful error messages
rather than just "file open failed".

DESCRIPTION
Implement gdb's "info proc" command by using the /proc interface
to print status information about any currently running process.
Examples of the use of "info proc" are:
Many changes to procfs.c, mostly to expand the "info proc" command and to fix a couple of small bugs. Changes to other files mostly to fix minor things pointed out by the SGI compiler. See ChangeLog for complete details.

info proc (prints summary info for current inferior)
info proc 123 (prints summary info for process with pid 123)
info proc mappings (prints address mappings)
info proc times (prints process/children times)
info proc id (prints pid, ppid, gid, sid, etc)
Make the /proc support a target-struct in its own right. * inferior.h (proc_wait, inferior_proc_init, proc_set_exec_trap): No longer global functions. (fork_inferior): New global function from fork-child.c. * inftarg.c (child_wait): Remove USE_PROC_FS conditional. (ptrace_me, ptrace_him): New stub functions for fork_inferior(). (child_create_inferior): Moved to fork-child.c as fork_inferior. (child_create_inferior): New tiny function that calls fork_inferior. * fork-child.c: New file, containing fork_inferior, which is built from slight mods to inftarg.c's child_create_inferior. * procfs.c (procfs_ops): Add target vector.

LOCAL FUNCTION

SYNOPSIS
void procfs_set_sproc_trap (void)
DESCRIPTION
This function sets up a trap on sproc system call exits so that we can
detect the arrival of a new thread. We are called with the child
stopped prior to it's first instruction.
Also note that we turn on the inherit-on-fork flag in the child process
so that any grand-children start with all tracing flags set.
