thorpej 1b6a66420e Regen; add sy_flags. 2001-01-27 07:23:06 +00:00
jdolecek 13ca559d39 Use CHECK_ALT_SYMLINK() instead CHECK_ALT_EXISTS() where appropriate.
This addresses kern/11757.

jdolecek e9e91a0fb5 split off thread specific stuff from struct sigacts to struct sigctx, leaving
only signal handler array sharable between threads
move other random signal stuff from struct proc to struct sigctx

This addresses kern/10981 by Matthew Orgass.

mycroft f495cd9dc6 Introduce 2 new flags in types.h:
* __HAVE_SYSCALL_INTERN.  If this is defined, e_syscall is replaced by
  e_syscall_intern, which is called at key places in the kernel.  This can be
  used to set a MD syscall handler pointer.  This obsoletes and replaces the
  *_HAS_SEPARATED_SYSCALL flags.
* __HAVE_MINIMAL_EMUL.  If this is defined, certain (deprecated) elements in
  struct emul are omitted.

jdolecek 87a6bee3a9 prototype ibcs2_syscall() in compat/ibcs2/ibcs2_exec.c 2000-12-09 12:45:44 +00:00
jdolecek a6ca890142 always fill in e_syscall in respective emul_*; if the emulation doesn't
have it's own separated *_syscall() function, use syscall()

jdolecek 65203b4ec6 if IBCS2_MACHDEP_HAS_SEPARATED_SYSCALL is defined, put ibcs2_syscall to
emul_ibcs2
define IBCS2_MACHDEP_HAS_SEPARATED_SYSCALL in i386 ibcs2_machdep.h
2000-12-02 16:09:44 +00:00
jdolecek f1badb80a7 put executable format specific code from ibcs2_exec.c to separate
files ibcs2_exec_coff.c, ibcs2_exec_elf32.c, ibcs2_exec_xout.c as
appropriate
2000-12-01 19:17:41 +00:00
jdolecek 01040d97a2 add e_path (emulation path) to struct emul, which replaces emulation-specific
*_emul_path variables

change macros CHECK_ALT_{CREAT|EXIST} to use that, 'root' doesn't need
to be passed explicitly any more and *_CHECK_ALT_{CREAT|EXIST} are removed
change explicit emul_find() calls in probe functions to get the emulation
path from the checked exec switch entry's emulation

remove no longer needed header files

add e_flags and e_syscall to struct emul; these are unsed and empty for now

jdolecek baae0324b9 restructure struct emul and execsw, in preparation to make emulations LKMable:
* move all exec-type specific information from struct emul to execsw[] and
  provide single struct emul per emulation
* elf:
  - kern/exec_elf32.c:probe_funcs[] is gone, execsw[] how has one entry
    per emulation and contains pointer to respective probe function
  - interp is allocated via MALLOC() rather than on stack
  - elf_args structure is allocated via MALLOC() rather than malloc()
* ecoff: the per-emulation hooks moved from alpha and mips specific code
  to OSF1 and Ultrix compat code as appropriate, execsw[] has one entry per
  emulation supporting ecoff with appropriate probe function
* the makecmds/probe functions don't set emulation, pointer to emulation is
  part of appropriate execsw[] entry
* constify couple of structures

jdolecek 78b866e95a change the type of *syscallnames[] array to 'const char * const foo[]' 2000-11-13 21:32:15 +00:00
sommerfeld 6b88a0fc51 Emulation stackgap sanity checks, based partly on fixes from
FreeBSD-SA00:42.

Change stackgap_alloc to bounds-check the allocation vs. the stack
gap, returning NULL if there isn't room for the allocation.

Change emul_find() to check for a NULL return from stackgap_alloc()
and convert that into ENAMETOOLONG.

Reorder various emulation syscalls so that all *_CHECK_ALT_{EXIST,CREAT}
calls (which turn into emul_find() under the covers come *after* small,
fixed-size stackgap_alloc() calls.

Clean up ibcs2 {get,set}groups.

to at least a block to make ufs_readdir happy.

matt 3c173d4927 If we loaded an nmagic on a subpage boundary, adjust epp->ep_d{addr,size} so
that they start on a page boundary.  This is needed so that obreak(2) works
properly.

matt a0cf752d0c For omagic & nmagic, add bss size into data magic (needed for brk to work
right).  Deal with the case that the data segment might fit into all the
trailing part of last text page.

mycroft e9deffe0bf Move a bunch of the COFF definitions into exec_coff.h, so they can be used by
other code.   XXX Not tested on SH3 yet.

chs a6d33cc1f2 add a new function vn_marktext() for exec code to let others know
that the vnode is now being used as process text.

simonb 2f1fef39b3 Centralise the declarations of cpu_model, machine, machine_arch,
osrelease, and ostype and remove "extern char foo[];" (for hostname
and domainname too).

Also delete redunctant decl of boottime in kern_info_43.c.

kleink 230876cf26 Merge parts of chs-ubc2 into the trunk:
* Remove the casts to vaddr_t from the round_page() and trunc_page() macros to
  make them type-generic, which is necessary i.e. to operate on file offsets
  without truncating them.
* In due course, cast pointer arguments to these macros to an appropriate
  integral type (paddr_t, vaddr_t).

Originally done by Chuck Silvers, updated by myself.

2000-01-10 03:16:25 +00:00
matt 8e42885010 Clean things up. Only include the ELF EXEC iff EXEC_ELF32 is already
asserted.

XXX -- this should mutate into kern/exec_coff someday with a cpu_coff_hooks
ala ecoff support.

matt 61783809dc rename ibcs2_sysi86 to ibcs2_sysmachine (since ibcs2 now runs on other
things than i386).
