730baa7431 fix sizeofs so they comply with the KNF style guide. yes, it is pedantic. 1998-07-31 22:50:48 +00:00

4b039671de When checking for overflow in the residual count, test against SSIZE_MAX. 
The read/write system calls return ssize_t because -1 is used to indicate
error, therefore the transfer size MUST be limited to SSIZE_MAX, otherwise
garbage can be returned to the user.

There is NO change from existing behavior here, only a more precise
definition of that the semantics are, except in the Alpha case, where
the full SSIZE_MAX transfer size can now be realized (ssize_t is 64-bit
on the Alpha).

6b1ff3c892 When copying out multiple control messages, ensure that the next control

b981fc4d34 Fix bug in recvit() that would cause recvmsg() to only receive one 
control message, even if there were multiple control messages on
the queue.  From Jean-Luc Richier <Jean-Luc.Richier@imag.fr>, in
bug report kern/4700.

8dd0293cd3 Use UCHAR_MAX rather than "255" when sanity-checking the length of a 
sockaddr in sockargs().

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.

c60b7587ab * catch up with system call argument type fixups/const poisoning. 
* Fix arguments to various copyin()/copyout() invocations, to avoid
  gratuitous casts.
* Some KNF formatting fixes
* Change sockargs()'s second argument to be a const void *, to help
  with dealing with the syscall argument type fixups/const poisoning.

d73abf41aa avoid unnecessary checks of m_get/MGET/etc.'s return values. When 
they're called with M_WAIT, they are defined to never return NULL.

49d52c9b1c Pass a proc pointer down to the usrreq and pcbbind functions for PRU_ATTACH, PRU_BIND and 
PRU_CONTROL.  The usrreq interface really needs to be split up, but this will have to wait.
Remove SS_PRIV completely.

1a5a3c9199 Extracted all of the compat_xxx routines, and created a library [libcompat] 
for them. There are a few #ifdef COMPAT_XX remaining, but they are not easy

fb371ccef0 tty_tb.c: need to include ioctl_compat.h in order to compile. 
sysv_shm.c: make shm_find_segment_by_shmid global so it can be used by
	    COMPAT_HPUX. There should be a better way...
rest: Add #ifdef COMPAT_HPUX where needed
