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.

  sysctl handlers to have access to the current thread, permitting work
  on implementing td->td_ucred, migration of suser() to using struct
  thread to derive the appropriate ucred, and allowing struct thread to be
  passed down to other code, such as network code where td is not currently
  available (and curproc is used).

o Note: netncp and netsmb are not updated to reflect this change, as they
  are not currently KSE-adapted.
