MFC: Remove linux_mib_destroy() since MTX_SYSINIT's gaining of a SYSUNINIT

Changes to MI Linux emulation code necessary to run 32-bit Linux binaries

2004-08-16T07:28:16+00:00

on AMD64, and the general case where the emulated platform has different
size pointers than we use natively:
- declare certain structure members as l_uintptr_t and use the new PTRIN
  and PTROUT macros to convert to and from native pointers.
- declare some structures __packed on amd64 when the layout would differ
  from that used on i386.
- include  instead of 
  if compiling with COMPAT_LINUX32. This will need to be revisited before
  32-bit and 64-bit Linux emulation support can coexist in the same kernel.
- other small scattered changes.

This should be a no-op on i386 and Alpha.

Use __FBSDID().

- Change the linux_[gs]et_os{name, release, s_version}() functions to

2003-03-13T22:45:43+00:00

  take a thread instead of a proc for their first argument.
- Add a mutex to protect the system-wide Linux osname, osrelease, and
  oss_version variables.
- Change linux_get_prison() to take a thread instead of a proc for its
  first argument and to use td_ucred rather than p_ucred.  This is ok
  because a thread's prison does not change even though it's ucred might.
- Also, change linux_get_prison() to return a struct prison * instead of
  a struct linux_prison * since it returns with the struct prison locked
  and this makes it easier to safely unlock the prison when we are done
  messing with it.

Back out M_* changes, per decision of the TRB.

Remove M_TRYWAIT/M_WAITOK/M_WAIT. Callers should use 0.

Merge M_NOWAIT/M_DONTWAIT into a single flag M_NOWAIT.

o Introduce pr_mtx into struct prison, providing protection for the

2001-12-03T16:12:27+00:00

  mutable contents of struct prison (hostname, securelevel, refcount,
  pr_linux, ...)
o Generally introduce mtx_lock()/mtx_unlock() calls throughout kern/
  so as to enforce these protections, in particular, in kern_mib.c
  protection sysctl access to the hostname and securelevel, as well as
  kern_prot.c access to the securelevel for access control purposes.
o Rewrite linux emulator abstractions for accessing per-jail linux
  mib entries (osname, osrelease, osversion) so that they don't return
  a pointer to the text in the struct linux_prison, rather, a copy
  to an array passed into the calls.  Likewise, update linprocfs to
  use these primitives.
o Update in_pcb.c to always use prison_getip() rather than directly
  accessing struct prison.
