* caif: fix MSG_OOB test in caif_seqpkt_recvmsg()Al Viro2015-03-151-1/+1
| | | | | | | | | | | | It should be checking flags, not msg->msg_flags. It's ->sendmsg() instances that need to look for that in ->msg_flags, ->recvmsg() ones (including the other ->recvmsg() instance in that file, as well as unix_dgram_recvmsg() this one claims to be imitating) check in flags. Braino had been introduced in commit dcda13 ("caif: Bugfix - use MSG_TRUNC in receive") back in 2010, so it goes quite a while back.

* caif: fix a signedness bug in cfpkt_iterate()Dan Carpenter2015-02-202-4/+4
| | | | | | | | | | | | | | | The cfpkt_iterate() function can return -EPROTO on error, but the function is a u16 so the negative value gets truncated to a positive unsigned short. This causes a static checker warning. The only caller which might care is cffrml_receive(), when it's checking the frame checksum. I modified cffrml_receive() so that it never says -EPROTO is a valid checksum. Also this isn't ever going to be inlined so I removed the "inline".

* caif: remove wrong dev_net_set() callNicolas Dichtel2015-01-291-1/+0
| | | | | | | | | | | | | | | | | src_net points to the netns where the netlink message has been received. This netns may be different from the netns where the interface is created (because the user may add IFLA_NET_NS_[PID|FD]). In this case, src_net is the link netns. It seems wrong to override the netns in the newlink() handler because if it was not already src_net, it means that the user explicitly asks to create the netdevice in another netns.

* net: Add and use skb_copy_datagram_msg() helper.David S. Miller2014-11-051-1/+1
| | | | | | | | | | | | | | | This encapsulates all of the skb_copy_datagram_iovec() callers with call argument signature "skb, offset, msghdr->msg_iov, length". When we move to iov_iters in the networking, the iov_iter object will sit in the msghdr. Having a helper like this means there will be less places to touch during that transformation.

* net: Fix use after free by removing length arg from sk_data_ready callbacks.David S. Miller2014-04-111-3/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Several spots in the kernel perform a sequence like: skb_queue_tail(&sk->s_receive_queue, skb); sk->sk_data_ready(sk, skb->len); But at the moment we place the SKB onto the socket receive queue it can be consumed and freed up. So this skb->len access is potentially to freed up memory. Furthermore, the skb->len can be modified by the consumer so it is possible that the value isn't accurate. And finally, no actual implementation of this callback actually uses the length argument. And since nobody actually cared about it's value, lots of call sites pass arbitrary values in such as '0' and even '1'. So just remove the length argument from the callback, that way there is no confusion whatsoever and all of these use-after-free cases get fixed as a side effect. Based upon a patch by Eric Dumazet and his suggestion to audit this issue tree-wide. Signed-off-by: David S. Miller <davem@davemloft.net>

* net: rework recvmsg handler msg_name and msg_namelen logicHannes Frederic Sowa2013-11-201-4/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch now always passes msg->msg_namelen as 0. recvmsg handlers must set msg_namelen to the proper size <= sizeof(struct sockaddr_storage) to return msg_name to the user. This prevents numerous uninitialized memory leaks we had in the recvmsg handlers and makes it harder for new code to accidentally leak uninitialized memory. Optimize for the case recvfrom is called with NULL as address. We don't need to copy the address at all, so set it to NULL before invoking the recvmsg handler. We can do so, because all the recvmsg handlers must cope with the case a plain read() is called on them. read() also sets msg_name to NULL. Also document these changes in include/linux/net.h as suggested by David Miller. Changes since RFC: Set msg->msg_name = NULL if user specified a NULL in msg_name but had a non-null msg_namelen in verify_iovec/verify_compat_iovec. This doesn't affect sendto as it would bail out earlier while trying to copy-in the address. It also more naturally reflects the logic by the callers of verify_iovec. With this change in place I could remove " if (!uaddr || msg_sys->msg_namelen == 0) msg->msg_name = NULL ". This change does not alter the user visible error logic as we ignore msg_namelen as long as msg_name is NULL. Also remove two unnecessary curly brackets in ___sys_recvmsg and change comments to netdev style.

* netvm: prevent a stream-specific deadlockMel Gorman2012-07-311-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch series is based on top of "Swap-over-NBD without deadlocking v15" as it depends on the same reservation of PF_MEMALLOC reserves logic. When a user or administrator requires swap for their application, they create a swap partition and file, format it with mkswap and activate it with swapon. In diskless systems this is not an option so if swap if required then swapping over the network is considered. The two likely scenarios are when blade servers are used as part of a cluster where the form factor or maintenance costs do not allow the use of disks and thin clients. The Linux Terminal Server Project recommends the use of the Network Block Device (NBD) for swap but this is not always an option. There is no guarantee that the network attached storage (NAS) device is running Linux or supports NBD. However, it is likely that it supports NFS so there are users that want support for swapping over NFS despite any performance concern. Some distributions currently carry patches that support swapping over NFS but it would be preferable to support it in the mainline kernel. Patch 1 avoids a stream-specific deadlock that potentially affects TCP. Patch 2 is a small modification to SELinux to avoid using PFMEMALLOC reserves. Patch 3 adds three helpers for filesystems to handle swap cache pages. For example, page_file_mapping() returns page->mapping for file-backed pages and the address_space of the underlying swap file for swap cache pages. Patch 4 adds two address_space_operations to allow a filesystem to pin all metadata relevant to a swapfile in memory. Upon successful activation, the swapfile is marked SWP_FILE and the address space operation ->direct_IO is used for writing and ->readpage for reading in swap pages. Patch 5 notes that patch 3 is bolting filesystem-specific-swapfile-support onto the side and that the default handlers have different information to what is available to the filesystem. This patch refactors the code so that there are generic handlers for each of the new address_space operations. Patch 6 adds an API to allow a vector of kernel addresses to be translated to struct pages and pinned for IO. Patch 7 adds support for using highmem pages for swap by kmapping the pages before calling the direct_IO handler. Patch 8 updates NFS to use the helpers from patch 3 where necessary. Patch 9 avoids setting PF_private on PG_swapcache pages within NFS. Patch 10 implements the new swapfile-related address_space operations for NFS and teaches the direct IO handler how to manage kernel addresses. Patch 11 prevents page allocator recursions in NFS by using GFP_NOIO where appropriate. Patch 12 fixes a NULL pointer dereference that occurs when using swap-over-NFS. With the patches applied, it is possible to mount a swapfile that is on an NFS filesystem. Swap performance is not great with a swap stress test taking roughly twice as long to complete than if the swap device was backed by NBD. This patch: netvm: prevent a stream-specific deadlock It could happen that all !SOCK_MEMALLOC sockets have buffered so much data that we're over the global rmem limit. This will prevent SOCK_MEMALLOC buffers from receiving data, which will prevent userspace from running, which is needed to reduce the buffered data. Fix this by exempting the SOCK_MEMALLOC sockets from the rmem limit. Once this change it applied, it is important that sockets that set SOCK_MEMALLOC do not clear the flag until the socket is being torn down. If this happens, a warning is generated and the tokens reclaimed to avoid accounting errors until the bug is fixed.

| * Kconfig: replace "--- help ---" with "---help---"Paul Bolle2012-05-071-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | There are three Kconfig entries with "--- help ---" attributes, and over 2000 Kconfig entries with "---help---" attributes. Apparently the three attributes with embedded spaces are valid. Still, I see little reason for using this obscure variant. And replacing those three attributes with the common variant makes grepping Kconfig files for help texts a bit easier too.

Traffic class mapping for different packet types: - control: TC_PRIO_CONTROL; - flow control: TC_PRIO_CONTROL; - at: TC_PRIO_CONTROL; - rfm: TC_PRIO_INTERACTIVE_BULK; - other sockets: equals to socket's TC; - network data: no change.
