[PATCH] virtio_ring: use u32 for virtio_max_dma_size
Both split ring and packed ring use 32bits to describe the length of a descriptor: see struct vring_desc and struct vring_packed_desc. This means the max segment size supported by virtio is U32_MAX. An example of virtio_max_dma_size in virtio_blk.c: u32 v, max_size; max_size = virtio_max_dma_size(vdev); -> implicit convert err = virtio_cread_feature(vdev, VIRTIO_BLK_F_SIZE_MAX, struct virtio_blk_config, size_max, &v); max_size = min(max_size, v); There is a risk during implicit convert here, once virtio_max_dma_siz...

a little note on sshbuf_reset()
...IT, 1)) != NULL) { buf->cd = buf->d = d; buf->alloc = SSHBUF_SIZE_INIT; } } explicit_bzero(buf->d, buf->alloc); } This function allocates a new buffer of size SSHBUF_SIZE_INIT if buf->alloc != SSHBUF_SIZE_INIT, which can put buf in an inconsistent state if buf->max_size < SSHBUF_SIZE_INIT, because it will make buf->alloc > buf->max_size true, which will trigger an error with a next call to sshbuf_check_sanity(). For example, struct sshbuf *buf = sshbuf_new(); sshbuf_set_max_size(buf, 100); sshbuf_reset(buf); will lead to SSH_ERR_INTERNAL_ERROR. This co...

How about a --min-size option, next to --max-size
There's a rather old bug report in Debian's bug tracking system (see http://bugs.debian.org/27126) about wanting to be able to specify the maximum file size, as well as the minimum file size. Here's the text: Sometimes, it's useful to specify a file size range one is interested in. For example, I'd like to keep an up-to-date mirror of Debian, but I currently

[PATCH] drm/virtio: fix bounds check in virtio_gpu_cmd_get_capset()
This doesn't affect runtime because in the current code "idx" is always valid. First, we read from "vgdev->capsets[idx].max_size" before checking whether "idx" is within bounds. And secondly the bounds check is off by one so we could end up reading one element beyond the end of the vgdev->capsets[] array.

A couple of questions about OpenSSH codebase
...ne allocation, two allocations if it is created with sshbuf_new(). There are a lot of times when they are allocated and freed within the same function. Same thing with bitmaps. What is the reason behind not allocating them on the stack? 2. A lot of stuff in sshbuf's functions is checked against max_size. What is the reason behind setting the max_size in the first place? If sshbuf instance is not read-only and doesn't have children, why it cannot allocate more memory than it's max_size? 3. There are a lot of very defensive checks in sshbuf code. A lot (if not all) of sshbuf_* functions that...
