@splice_desc.total_len is 32 bit(unsigned int) which is used to store the size passed from userspace which is 64 bit(size_t) so that the size is unexpectedly truncated That means vmsplice can not work if the size passed from userspace is >= 4G, for example, we noticed in vmsplice, splice-reader does not do anything and splice-writer is waiting for available buffer forever if the size is 4G Fix it by extending @splice_desc.total_len to 64 bits as well Signed-off-by: Xiao Guangrong <xiaoguangrong@linux.vnet.ibm.com> Cc: Jens Axboe <axboe@kernel.dk> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> |
