git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs David Howells says: ==================== rxrpc: Support service upgrade Here's a set of patches that allow AF_RXRPC to support the AuriStor service upgrade facility. This allows the server to change the service ID requested to an upgraded service if the client requests it upon the initiation of a connection. This is used by the AuriStor AFS-compatible servers to implement IPv6 handling and improved facilities by providing improved volume location, volume, protection, file and cache management services. Note that certain parts of the AFS protocol carry hard-coded IPv4 addresses. The reason AuriStor does it this way is that probing the improved service ID first will not incur an ABORT or any other response on some servers if the server is not listening on it - and so one have to employ a timeout. This is implemented in the server by allowing an AF_RXRPC server to call bind() twice on a socket to allow it to listen on two service IDs and then call setsockopt() to instruct the server to upgrade one into the other if the client requests it (by setting userStatus to 1 on the first DATA packet on a connection). If the upgrade occurs, all further operations on that connection are done with the new service ID. AF_RXRPC has to handle this automatically as connections are not exposed to userspace. Clients can request this facility by setting an RXRPC_UPGRADE_SERVICE command in the sendmsg() control buffer and then observing the resultant service ID in the msg_addr returned by recvmsg(). This should only be used to probe the service. Clients should then use the returned service ID in all subsequent communications with that server. Note that the kernel will not retain this information should the connection expire from its cache. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

2017-06-05rxrpc: Add service upgrade support for client connectionsDavid Howells
Make it possible for a client to use AuriStor's service upgrade facility. The client does this by adding an RXRPC_UPGRADE_SERVICE control message to the first sendmsg() of a call. This takes no parameters. When recvmsg() starts returning data from the call, the service ID field in the returned msg_name will reflect the result of the upgrade attempt. If the upgrade was ignored, srx_service will match what was set in the sendmsg(); if the upgrade happened the srx_service will be altered to indicate the service the server upgraded to. Note that: (1) The choice of upgrade service is up to the server (2) Further client calls to the same server that would share a connection are blocked if an upgrade probe is in progress. (3) This should only be used to probe the service. Clients should then use the returned service ID in all subsequent communications with that server (and not set the upgrade). Note that the kernel will not retain this information should the connection expire from its cache. (4) If a server that supports upgrading is replaced by one that doesn't, whilst a connection is live, and if the replacement is running, say, OpenAFS 1.6.4 or older or an older IBM AFS, then the replacement server will not respond to packets sent to the upgraded connection. At this point, calls will time out and the server must be reprobed. Signed-off-by: David Howells <dhowells@redhat.com>
2017-06-05rxrpc: Implement service upgradeDavid Howells
Implement AuriStor's service upgrade facility. There are three problems that this is meant to deal with: (1) Various of the standard AFS RPC calls have IPv4 addresses in their requests and/or replies - but there's no room for including IPv6 addresses. (2) Definition of IPv6-specific RPC operations in the standard operation sets has not yet been achieved. (3) One could envision the creation a new service on the same port that as the original service. The new service could implement improved operations - and the client could try this first, falling back to the original service if it's not there. Unfortunately, certain servers ignore packets addressed to a service they don't implement and don't respond in any way - not even with an ABORT. This means that the client must then wait for the call timeout to occur. What service upgrade does is to see if the connection is marked as being 'upgradeable' and if so, change the service ID in the server and thus the request and reply formats. Note that the upgrade isn't mandatory - a server that supports only the original call set will ignore the upgrade request. In the protocol, the procedure is then as follows: (1) To request an upgrade, the first DATA packet in a new connection must have the userStatus set to 1 (this is normally 0). The userStatus value is normally ignored by the server. (2) If the server doesn't support upgrading, the reply packets will contain the same service ID as for the first request packet. (3) If the server does support upgrading, all future reply packets on that connection will contain the new service ID and the new service ID will be applied to *all* further calls on that connection as well. (4) The RPC op used to probe the upgrade must take the same request data as the shadow call in the upgrade set (but may return a different reply). GetCapability RPC ops were added to all standard sets for just this purpose. Ops where the request formats differ cannot be used for probing. (5) The client must wait for completion of the probe before sending any further RPC ops to the same destination. It should then use the service ID that recvmsg() reported back in all future calls. (6) The shadow service must have call definitions for all the operation IDs defined by the original service. To support service upgrading, a server should: (1) Call bind() twice on its AF_RXRPC socket before calling listen(). Each bind() should supply a different service ID, but the transport addresses must be the same. This allows the server to receive requests with either service ID. (2) Enable automatic upgrading by calling setsockopt(), specifying RXRPC_UPGRADEABLE_SERVICE and passing in a two-member array of unsigned shorts as the argument: unsigned short optval[2]; This specifies a pair of service IDs. They must be different and must match the service IDs bound to the socket. Member 0 is the service ID to upgrade from and member 1 is the service ID to upgrade to.

2017-06-04skbuff: return -EMSGSIZE in skb_to_sgvec to prevent overflowJason A. Donenfeld
This is a defense-in-depth measure in response to bugs like 4d6fa57b4dab ("macsec: avoid heap overflow in skb_to_sgvec"). There's not only a potential overflow of sglist items, but also a stack overflow potential, so we fix this by limiting the amount of recursion this function is allowed to do. Not actually providing a bounded base case is a future disaster that we can easily avoid here. As a small matter of house keeping, we take this opportunity to move the documentation comment over the actual function the documentation is for. While this could be implemented by using an explicit stack of skbuffs, when implementing this, the function complexity increased considerably, and I don't think such complexity and bloat is actually worth it. So, instead I built this and tested it on x86, x86_64, ARM, ARM64, and MIPS, and measured the stack usage there. I also reverted the recent MIPS changes that give it a separate IRQ stack, so that I could experience some worst-case situations. I found that limiting it to 24 layers deep yielded a good stack usage with room for safety, as well as being much deeper than any driver actually ever creates. Signed-off-by: Jason A.

2017-05-25bpf: add various verifier test casesDaniel Borkmann
This patch adds various verifier test cases: 1) A test case for the pruning issue when tracking alignment is used. 2) Various PTR_TO_MAP_VALUE_OR_NULL tests to make sure pointer arithmetic turns such register into UNKNOWN_VALUE type. 3) Test cases for the special treatment of LD_ABS/LD_IND to make sure verifier doesn't break calling convention here. Latter is needed, since f.e. arm64 JIT uses r1 - r5 for storing temporary data, so they really must be marked as NOT_INIT.

2017-05-24vlan: Fix tcp checksum offloads in Q-in-Q vlansVlad Yasevich
It appears that TCP checksum offloading has been broken for Q-in-Q vlans. The behavior was execerbated by the series commit afb0bc972b52 ("Merge branch 'stacked_vlan_tso'") that that enabled accleleration features on stacked vlans. However, event without that series, it is possible to trigger this issue. It just requires a lot more specialized configuration. The root cause is the interaction between how netdev_intersect_features() works, the features actually set on the vlan devices and HW having the ability to run checksum with longer headers. The issue starts when netdev_interesect_features() replaces NETIF_F_HW_CSUM with a combination of NETIF_F_IP_CSUM | NETIF_F_IPV6_CSUM, if the HW advertises IP|IPV6 specific checksums. This happens for tagged and multi-tagged packets. However, HW that enables IP|IPV6 checksum offloading doesn't gurantee that packets with arbitrarily long headers can be checksummed. This patch disables IP|IPV6 checksums on the packet for multi-tagged packets.
