The secure interrupt is only useful to secure world, therefore for NS users it shouldn't be required. Make it optional. This fixes a warning on Arm Juno board: mhu@2b1f0000: interrupts: [[0, 36, 4], [0, 35, 4]] is too short Signed-off-by:

Al Viro authored
Most of the users immediately follow successful iov_iter_get_pages() with advancing by the amount it had returned. Provide inline wrappers doing that, convert trivial open-coded uses of those. BTW, iov_iter_get_pages() never returns more than it had been asked to; such checks in cifs ought to be removed someday... Reviewed-by:

All call sites of get_pages_array() are essenitally identical now. Replace with common helper... Returns number of slots available in resulting array or 0 on OOM; it's up to the caller to make sure it doesn't ask to zero-entry array (i.e. neither maxpages nor size are allowed to be zero).

... and don't mangle maxsize there - turn the loop into counting one instead. Easier to see that we won't run out of array that way. Note that special treatment of the partial buffer in that thing is an artifact of the non-advancing semantics of iov_iter_get_pages() - if not for that, it would be append_pipe(), same as the body of the loop that follows it. IOW, once we make iov_iter_get_pages() advancing, the whole thing will turn into calculate how many pages do we want allocate an array (if needed) call append_pipe() that many times. Reviewed-by:

same as for pipes Reviewed-by:
-
Al Viro authored
The differences between those two are * pipe_get_pages() gets a non-NULL struct page ** value pointing to preallocated array + array size. * pipe_get_pages_alloc() gets an address of struct page ** variable that contains NULL, allocates the array and (on success) stores its address in that variable. Not hard to combine - always pass struct page ***, have the previous pipe_get_pages_alloc() caller pass ~0U as cap for array size. Reviewed-by:

zero maxpages is bogus, but best treated as "just return 0"; NULL pages, OTOH, should be treated as a hard bug. get rid of now completely useless checks in xarray_get_pages{,_alloc}(). Reviewed-by: -

All their callers are next to each other; all of them want the total amount of pages and, possibly, the offset in the partial final buffer. Combine into a new helper (pipe_npages()), fix the bogosity in pipe_space_for_user(), while we are at it. Signed-off-by: -

We often need to find whether the last buffer is anon or not, and currently it's rather clumsy: check if ->iov_offset is non-zero (i.e. that pipe is not empty) if so, get the corresponding pipe_buffer and check its ->ops if it's &default_pipe_buf_ops, we have an anon buffer. Let's replace the use of ->iov_offset (which is nowhere near similar to its role for other flavours) with signed field (->last_offset), with the following rules: empty, no buffers occupied: 0 anon, with bytes up to N-1 filled: N zero-copy, with bytes up to N-1 filled: -N That way abs(i->last_offset) is equal to what used to be in i->iov_offset and empty vs. anon vs. zero-copy can be distinguished by the sign of i->last_offset. Checks for "should we extend the last buffer or should we start a new one?" become easier to follow that way. Note that most of the operations can only be done in a sane state - i.e. when the pipe has nothing past the current position of iterator. About the only thing that could be done outside of that state is iov_iter_advance(), which transitions to the sane state by truncating the pipe. There are only two cases where we leave the sane state: 1) iov_iter_get_pages()/iov_iter_get_pages_alloc(). Will be dealt with later, when we make get_pages advancing - the callers are actually happier that way. 2) iov_iter copied, then something is put into the copy. Since they share the underlying pipe, the original gets behind. When we decide that we are done with the copy (original is not usable until then) we advance the original. direct_io used to be done that way; nowadays it operates on the original and we do iov_iter_revert() to discard the excessive data. At the moment there's nothing in the kernel that could do that to ITER_PIPE iterators, so this reason for insane state is theoretical right now. Signed-off-by: -

Fold pipe_truncate() into it, clean up. We can release buffers in the same loop where we walk backwards to the iterator beginning looking for the place where the new position will be. Signed-off-by: -
Al Viro authored
instead of setting ->iov_offset for new position and calling pipe_truncate() to adjust ->len of the last buffer and discard everything after it, adjust ->len at the same time we set ->iov_offset and use pipe_discard_from() to deal with buffers past that. Signed-off-by: -

it's only used to get to the partial buffer we can add to, and that's always the last one, i.e. pipe->head - 1. Signed-off-by: -

Expand the only remaining call of push_pipe() (in __pipe_get_pages()), combine it with the page-collecting loop there. Note that the only reason it's not a loop doing append_pipe() is that append_pipe() is advancing, while iov_iter_get_pages() is not. As soon as it switches to saner semantics, this thing will switch to using append_pipe(). Signed-off-by:
