for July 17: early crash on x86-64) SELinux needs MAY_APPEND to be passed down to the security hook. Otherwise, we get permission denials when only append permission is granted by policy even if the opening process specified O_APPEND. Shows up as a regression in the ltp selinux testsuite, fixed by this patch. Signed-off-by:

The iov_iter_advance() function would look at the iov->iov_len entry even though it might have iterated over the whole array, and iov was pointing past the end. This would cause DEBUG_PAGEALLOC to trigger a kernel page fault if the allocation was at the end of a page, and the next page was unallocated. The quick fix is to just change the order of the tests: check that there is any iovec data left before we check the iov entry itself. Thanks to Alexey Dobriyan for finding this case, and testing the fix. Reported-and-tested-by:

We zero-fill them like we are supposed to, and that's all fine. It's only an error if the 'romfs_copyfrom()' routine isn't able to fill the data that is supposed to be there. Most of the patch is really just re-organizing the code a bit, and using separate variables for the error value and for how much of the page we actually filled from the filesystem.
