thorpej e95c22ee96 Don't cast the null residual pointer passed to vn_rdwr(). 1998-07-28 18:17:34 +00:00
thorpej 80e25bcca0 Don't cast the null residual pointer passed to vn_rdwr(). 1998-07-28 18:11:39 +00:00
thorpej 939279f988 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).

thorpej bf51a1d137 uvm_deallocate() takes an address and a size, not an address range. From
ITOH Yasufumi <yasufu-i@is.aist-nara.ac.jp>, PR #5834.

thorpej fc4828b0b4 A few small changes to how pool pages are allocated/freed:
- If either an alloc or release function is provided, make sure both are
  provided, otherwise panic, as this is a fatal error.
- If using the default allocator, default the pool pagesz to PAGE_SIZE,
  since that is the granularity of the default allocator's mechanism.
- In the default allocator, use new functions:
	uvm_km_alloc_poolpage()/uvm_km_free_poolpage(), or
	kmem_alloc_poolpage()/kmem_free_poolpage()
  rather than doing it here.  These functions may use pmap hooks to
  provide alternate methods of mapping pool pages.

thorpej e5f49cece3 Regen: pad off_t args in pread/pwrite/preadv/pwritev. 1998-07-02 01:24:24 +00:00
thorpej d4e618b3a5 Argh, pad the off_t args in pread/pwrite/preadv/pwritev. System call
numbers don't change since the window of brokenness was so small (1 day).

thorpej f0dda0d383 Add positional read and write system calls:
- pread() (#173) and pwrite() (#174), which are defined by XPG4.2.  System
  call numbers match Solaris.
- preadv() (#289) and pwritev() (#290), which are the positional cousins
  of readv() and writev(), but not defined by any standard.
