pk 37d77087e8 Check `b_dev' field in bdwrite() before using it as an index into bdevsw[].
`b_dev' value of NODEV happens and is normal if the buffer is on its way
to the underlying device strategy function for the first time.

Also, MFS sillily uses a major device number (255) which cannot be used
to index bdevsw[]. Check marked with XXXs.

pk b7b1073fd0 In bread() and breadn(): if getblk() returns a DELWRI buffer, don't
call biowait() but return `success' immediately. We can return `success'
because buffers with recorded errors are not returned by getblk().
(Takes care of PR#3694).

christos 2b0c0d95ab Make this work for SETUIDSCRIPTS:
- include <sys/stat.h> for S_ISUID, S_ISGID
- fix bug where shortcut to fail would use uninitialized variables.
- elide other warnings.

cgd 6542ece8e1 mark prototypes for static inline functions in the generated files as
possibly unused (with __attribute__ ((unused))), to avoid generating
warnings when compiling without optimization but with most ports' default
warning flags.

fvdl 6eecd789e6 There appear to be spinlock bugs in the VM code. They are not a problem
now, as we're always one on CPU (they will be later, though). With DEBUG,
they cause a lot of output, so DEBUG -> LOCKDEBUG for now.

thorpej 8dd0293cd3 Use UCHAR_MAX rather than "255" when sanity-checking the length of a
sockaddr in sockargs().
1997-06-26 06:13:36 +00:00
thorpej 1351e629b3 Several small changes to eliminate kludginess in dealing with unix domain
socket names:
- In unp_setsockaddr() and unp_setpeeraddr(), if the socket name can't
  fit into a single mbuf, allocate enough external storage space to
  hold it.
- In unp_bind() and unp_connect(), perform a similar operation, but allocate
  one extra byte, and ensure that the pathname is nul-terminated.
Many thanks to enami tsugutomo <enami@cv.sony.co.jp> for the sanity
checking.

thorpej e1fb68eb29 In sockargs():
- Add a comment describing my feelings about this interface, in general.
- Remove the COMPAT_OLDSOCK length hack.  Instead, if the socket argument
  is too long to fit in an mbuf, allocate enough external storage to
  hold it.
- If the socket argument is a sockaddr, don't allow the length to be
  greater than 255, as that would overflow sa_len.
Many thanks to enami tsugutomo <enami@cv.sony.co.jp> for his sanity checking.

thorpej 01cbda9800 In sbappendaddr(), if the sockaddr length is larger than will fit in

thorpej 6043eb7d80 Avoid running off the end of the format string if the caller botched
the format modifer.  Reported by and suggested fix from Daniel G. Pouzzner
in PR #2633.  Final fix is slightly different now that we support the %q
modifier.  This fix also includes the equivalent fix for sprintf().

fvdl 4702f17abc Add functions to set/reset the info about the publicly exported
(WebNFS) filesystem. At first glance this should go into the
NFS code, but all the other export code is here as well.

thorpej cd730bdd50 In sosetopt():
- Disallow < 1 values for SO_SNDBUF, SO_RCVBUF, SO_SNDLOWAT, and
  SO_RCVLOWAT; return EINVAL if the user attempts to set <= 0.
  Inspired by PR #3770, from Havard Eidnes <he@vader.runit.sintef.no>.
- For SO_SNDLOWAT and SO_RCVLOWAT, don't let the low-water mark get
  set above the high-water mark.  Behavior is now consistent with
  BSD/OS: If such an attempt is made, silently truncate to the high-water
  value.

thorpej a149ed59e4 Eliminate use of dtom() in the handing of UNIX domain sockets. Add an

thorpej e94c4d3f1c Call cpu_dumpconf() after cpu_rootconf(). 1997-06-14 04:18:34 +00:00
thorpej 91f7efbaf9 Fix crash dump device selection after the recent swap changes:
- If RB_ASKNAME, prompt for the dump device, defaulting to
  partition 'b' of the root device, if the root device is a disk.
- Else, if dumpspec is set to "none", do not configure a dump device.
- Else, if dumpspec is set by config(8), attempt to use that device.
- Else, dumpspec is wildcarded or unspecified; if the root device is
  a disk, select partition b.  (which was the previous default dump
  partition)

Note, dumps to a local disk now work even if root is on nfs.
