* Kernel buffers
|
|
*
|
|
* KBuffer Typedef for a kernel buffer.
|
|
*
|
|
* KB_NEXT(bfr) Access next buffer in chain (r/w).
|
|
* KB_LEN(bfr) Access length of data in this buffer (r/w).
|
|
* KB_QNEXT(bfr) Access next buffer in queue (r/w).
|
|
*
|
|
* KB_ALLOC(bfr, size, flags, type)
|
|
* Allocates a new kernel buffer of at least size bytes.
|
|
* KB_ALLOCPKT(bfr, size, flags, type)
|
|
* Allocates a new kernel packet header buffer of at
|
|
* least size bytes.
|
|
* KB_ALLOCEXT(bfr, size, flags, type)
|
|
* Allocates a new kernel buffer with external storage
|
|
* of at least size bytes.
|
|
* KB_FREEONE(bfr, nxt) Free buffer bfr and set next buffer in chain in nxt.
|
|
* KB_FREEALL(bfr) Free bfr's entire buffer chain.
|
|
* KB_COPY(bfr, off, len, new, flags)
|
|
* Copy len bytes of user data from buffer bfr starting at
|
|
* byte offset off and return new buffer chain in new.
|
|
* If len is KB_COPYALL, copy until end of chain.
|
|
* KB_COPYDATA(bfr, off, len, datap)
|
|
* Copy data from buffer bfr starting at byte offset off
|
|
* for len bytes into the data area pointed to by datap.
|
|
* Returns the number of bytes not copied to datap.
|
|
* KB_PULLUP(bfr, n, new)
|
|
* Get at least the first n bytes of data in the buffer
|
|
* chain headed by bfr contiguous in the first buffer.
|
|
* Returns the (potentially new) head of the chain in new.
|
|
* On failure the chain is freed and NULL is returned.
|
|
* KB_LINKHEAD(new, head)
|
|
* Link the kernel buffer new at the head of the buffer
|
|
* chain headed by head. If both new and head are
|
|
* packet header buffers, new will become the packet
|
|
* header for the chain.
|
|
* KB_LINK(new, prev)
|
|
* Link the kernel buffer new into the buffer chain
|
|
* after the buffer prev.
|
|
* KB_UNLINKHEAD(head, next)
|
|
* Unlink the kernel buffer from the head of the buffer
|
|
* chain headed by head. The buffer head will be freed
|
|
* and the new chain head will be placed in next.
|
|
* KB_UNLINK(old, prev, next)
|
|
* Unlink the kernel buffer old with previous buffer prev
|
|
* from its buffer chain. The following buffer in the
|
|
* chain will be placed in next and the buffer old will
|
|
* be freed.
|
|
* KB_ISPKT(bfr) Tests whether bfr is a packet header buffer.
|
|
* KB_ISEXT(bfr) Tests whether bfr has external storage.
|
|
* KB_BFRSTART(bfr, x, t)
|
|
* Sets x (cast to type t) to point to the start of the
|
|
* buffer space in bfr.
|
|
* KB_BFREND(bfr, x, t)
|
|
* Sets x (cast to type t) to point one byte past the end
|
|
* of the buffer space in bfr.
|
|
* KB_BFRLEN(bfr) Returns length of buffer space in bfr.
|
|
* KB_DATASTART(bfr, x, t)
|
|
* Sets x (cast to type t) to point to the start of the
|
|
* buffer data contained in bfr.
|
|
* KB_DATAEND(bfr, x, t)
|
|
* Sets x (cast to type t) to point one byte past the end
|
|
* of the buffer data contained in bfr.
|
|
* KB_HEADSET(bfr, n) Sets the start address for buffer data in buffer bfr to
|
|
* n bytes from the beginning of the buffer space.
|
|
* KB_HEADMOVE(bfr, n) Adjust buffer data controls to move data down (n > 0)
|
|
* or up (n < 0) n bytes in the buffer bfr.
|
|
* KB_HEADADJ(bfr, n) Adjust buffer data controls to add (n > 0) or subtract
|
|
* (n < 0) n bytes of data to/from the beginning of bfr.
|
|
* KB_TAILADJ(bfr, n) Adjust buffer data controls to add (n > 0) or subtract
|
|
* (n < 0) n bytes of data to/from the end of bfr.
|
|
* KB_TAILALIGN(bfr, n) Set buffer data controls to place an object of size n
|
|
* at the end of bfr, longword aligned.
|
|
* KB_HEADROOM(bfr, n) Set n to the amount of buffer space available before
|
|
* the start of data in bfr.
|
|
* KB_TAILROOM(bfr, n) Set n to the amount of buffer space available after
|
|
* the end of data in bfr.
|
|
* KB_PLENGET(bfr, n) Set n to bfr's packet length.
|
|
* KB_PLENSET(bfr, n) Set bfr's packet length to n.
|
|
* KB_PLENADJ(bfr, n) Adjust total packet length by n bytes.
