mycroft e45ef6abcd Emulate the Linux DVD_* ioctls(2). This gets us 90% of the way to running the
LiViD DVD player.  (See forthcoming mail to current-users.)
XXX NOTE: We should do something to probe capabilities, rather than allowing
these ioctls on any device.

thorpej c581bf97c5 A few things to make the Linux clone(2) emulation work a bit better:
- When the exit signal is specified to be 0, don't just assume they
  meant SIGCHLD.  In the Linux world, this appears to mean "don't deliver
  an exit signal at all".
- Simplify P_EXITSIG(); don't check against initproc here, just change
  the exit signal to SIGCHLD if reparenting to initproc.

A very simple clone(2) test program now works, and the MpegTV package
starts, but doesn't run properly yet (I believe there is a separate
bug which keeps it from working properly).

cgd af8a9059d3 compute the value to be used for e_arglen via howmany(value, sizeof (char *)),
rather than just "value / sizeof (char *)".  While in these cases the latter
works as well, the former's a better example for other uses to copy (since
it handles the non-integral multiple case correctly).

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.
1998-09-11 12:50:05 +00:00
rvb 26b955eec7 ufs_readdir no longer checks if vp->v_type != VDIR so

EINVAL for them too.

kleink c80051ee4e Add missing preparation of F_GETLK parameters in linux_sys_fcntl(); fixes PR
port-i386/4083 from Matthias Scheler <tron@lyssa.owl.de>, but vastly cleaned
up as previously suggested by myself.

bouyer 1cd83a5971 Fix "missing entries" bug when reading large directories: When reading a
directory and running out of space in the dest buffer, off should point to the
current entry (which was not saved) and not to the next.
I discovered this bug using linux and SunOS emulation over NFS, but seems to
affect other emulations as well.

augustss 9745684ebe Changes to the sudio system:
- It is now possible to handle devices that want "looping" DMA,
    e.g. the SoundBlaster correctly.  The WSS and SB drivers use this.
    To do this several new methods were introduced in audio_hw_if.
  - Different silence handling (forced by previous change).
  - The audio driver can now be mmap()-ed, but due to problems in
    the VM system only for writing for now.
  - The OSS (Linux) audio emulation takes advantage of some of the
    new features.
