erh c7176f00e4 The siginfo include line is not needed here anymore. 1998-10-07 22:17:57 +00:00
fvdl 8096c25afc Assign my copyright to TNF. Merge with others were appropriate.

mycroft fb526e055c Substantial signal handling changes:
* Increase the size of sigset_t to accomodate 128 signals -- adding new
  versions of sys_setprocmask(), sys_sigaction(), sys_sigpending() and
  sys_sigsuspend() to handle the changed arguments.
* Abstract the guts of sys_sigaltstack(), sys_setprocmask(), sys_sigaction(),
  sys_sigpending() and sys_sigsuspend() into separate functions, and call them
  from all the emulations rather than hard-coding everything.  (Avoids uses
  the stackgap crap for these system calls.)
* Add a new flag (p_checksig) to indicate that a process may have signals
  pending and userret() needs to do the full (slow) check.
* Eliminate SAS_ALTSTACK; it's exactly the inverse of SS_DISABLE.
* Correct emulation bugs with restoring SS_ONSTACK.
* Make the signal mask in the sigcontext always use the emulated mask format.
* Store signals internally in sigaction structures, rather than maintaining a
  bunch of little sigsets for each SA_* bit.
* Keep track of where we put the signal trampoline, rather than figuring it out
  in *_sendsig().
* Issue a warning when a non-emulated sigaction bit is observed.
* Add missing emulated signals, and a native SIGPWR (currently not used).
* Implement the `not reset when caught' semantics for relevant signals.

Note: Only code touched by the i386 port has been modified.  Other ports and
emulations need to be updated.

thorpej 37b70b3064 Change the "aresid" argument of vn_rdwr() from an int * to a size_t *,
to match the new uio_resid type.

cgd 912e6fef44 include <sys/exec.h> rather than <machine/exec.h> 1996-10-07 21:47:33 +00:00
jtk fb2727b7e6 update to compile; needs new enum name 'Elf_sht_progbits' 1996-10-05 00:12:49 +00:00
cgd 65148dea43 kill (re)definitions of EXEC_ELF32. They're no longer necessary
(because of the EXEC_* option changes), and now cause warnings.
1996-10-03 05:02:05 +00:00
thorpej 8dd444adbd Fix a section header check that didn't get updated with the elf32/elf64
changes.  Make this compile again with the new EXEC_* options.

christos 76f9ea8676 Elf32_sht_progbits -> Elf_sht_progbits 1996-09-30 23:56:01 +00:00
cgd 7c3255776d slightly clean up some of the changes made when ELF64 support went in 1996-09-27 18:14:23 +00:00
cgd 9c3e274c7b adapt ELF-using compat code to use new ELF definitions/code. At this point,
these are restricted to 32-bit ELF, and should be severely cleaned.

mycroft a8fd25767d Define execv() and execve() consistently across emulations.
Do path name translation.

christos 4d9a6e0930 - Pass the Elf32_Ehdr in the linux probe function, and use it!
Since linux binaries are (mostly) always compiled with gcc, look for
the gcc signature in the .comment section header: "\0 GCC: (GNU) ".
I've changed the probe order in kern/exec_elf.c to probe for linux ELF
binaries first and fall back to SVR4 binaries. This makes statically
linked binaries work for both linux and svr4. Note that gcc-compiled
svr4 binaries, still contain the operating system signature first and
then the GCC signature, so there is no conflict. Yes this is a hack.

christos 151fa70f78 Prototyping changes. 1996-04-05 00:01:10 +00:00
mycroft 245f292fed Prefix names of system call implementation functions with `sys_'. 1995-10-07 06:25:19 +00:00
thorpej e1da0d5390 Make system calls conform to a standard prototype and bring those
prototypes into scope.

christos 6b95b513b0 Use compat_util.[ch]. 1995-06-24 20:20:04 +00:00
fvdl c4aaa6000c * Changed to use generic ELF code from kern/exec_elf.c (which was taken
from the svr4 exec code plus the linux compat mods)
* Include file change
* Add multicast sockopts (from John Brezak)
1995-06-22 21:34:27 +00:00
fvdl fb777788b1 Don't forget to acknowledge that all the ELF stuff was taken from
Christos' svr4 code.
1995-06-11 15:15:09 +00:00
fvdl fc7cfb5f0b * Make Linux ELF binaries work. Lots of code duplication, but it will have to do
for now.
* Add a sanity check in linux_uselib

christos 44eef7c28b - added struct emul to all emulations.
- removed all setup functions.
- added copyargs() functions where needed.

fvdl 623f1e3986 Handle Linux signal tramp code differently. Some changes because of the
now seperate Linux signal trampoline code. Add linux_sigreturn to
syscalls.master.
1995-04-07 22:23:22 +00:00
fvdl 182c23c8bc Added a few more system calls.
More consistent alternate root file semantics throughout.
