In 882716604ec "pktgen: fix multiple queue warning" we added special logic to handle the case where ntxq is zero. It's not clear to me that ntxq can actually be zero. But if it were then we would set ->queue_map_min and ->queue_map_max to USHRT_MAX when probably we want to set them to zero? Signed-off-by: David S. Miller <davem@davemloft.net>

2012-01-07net: fix sock_clone reference mismatch with tcp memcontrolGlauber Costa
Sockets can also be created through sock_clone. Because it copies all data in the sock structure, it also copies the memcg-related pointer, and all should be fine. However, since we now use reference counts in socket creation, we are left with some sockets that have no reference counts. It matters when we destroy them, since it leads to a mismatch.

2012-01-05vfs: fix up ENOIOCTLCMD error handlingLinus Torvalds
We're doing some odd things there, which already messes up various users (see the net/socket.c code that this removes), and it was going to add yet more crud to the block layer because of the incorrect error code translation. ENOIOCTLCMD is not an error return that should be returned to user mode from the "ioctl()" system call, but it should *not* be translated as EINVAL ("Invalid argument"). It should be translated as ENOTTY ("Inappropriate ioctl for device"). That EINVAL confusion has apparently so permeated some code that the block layer actually checks for it, which is sad. We continue to do so for now, but add a big comment about how wrong that is, and we should remove it entirely eventually. In the meantime, this tries to keep the changes localized to just the EINVAL -> ENOTTY fix, and removing code that makes it harder to do the right thing.

2012-01-05net_sched: red: split red_parms into parms and varsEric Dumazet
This patch splits the red_parms structure into two components. One holding the RED 'constant' parameters, and one containing the variables. This permits a size reduction of GRED qdisc, and is a preliminary step to add an optional RED unit to SFQ. SFQRED will have a single red_parms structure shared by all flows, and a private red_vars per flow.

2012-01-05net_sched: sfq: extend limitsEric Dumazet
SFQ as implemented in Linux is very limited, with at most 127 flows and limit of 127 packets. [ So if 127 flows are active, we have one packet per flow ] This patch brings to SFQ following features to cope with modern needs. - Ability to specify a smaller per flow limit of inflight packets. (default value being at 127 packets) - Ability to have up to 65408 active flows (instead of 127) - Ability to have head drops instead of tail drops (to drop old packets from a flow) Example of use : No more than 20 packets per flow, max 8000 flows, max 20000 packets in SFQ qdisc, hash table of 65536 slots. tc qdisc add ... sfq \ flows 8000 \ depth 20 \ headdrop \ limit 20000 \ divisor 65536 Ram usage : 2 bytes per hash table entry (instead of previous 1 byte/entry) 32 bytes per flow on 64bit arches, instead of 384 for QFQ, so much better cache hit ratio.

2012-01-05NFSv4: include bitmap in nfsv4 get acl dataAndy Adamson
The NFSv4 bitmap size is unbounded: a server can return an arbitrary sized bitmap in an FATTR4_WORD0_ACL request. Replace using the nfs4_fattr_bitmap_maxsz as a guess to the maximum bitmask returned by a server with the inclusion of the bitmap (xdr length plus bitmasks) and the acl data xdr length to the (cached) acl page data. This is a general solution to commit e5012d1f "NFSv4.1: update nfs4_fattr_bitmap_maxsz" and fixes hitting a BUG_ON in xdr_shrink_bufhead when getting ACLs. Fix a bug in decode_getacl that returned -EINVAL on ACLs > page when getxattr was called with a NULL buffer, preventing ACL > PAGE_SIZE from being retrieved.

2012-01-04ipv6: Check RA for sllao when configuring optimistic ipv6 address (v2)Neil Horman
Recently Dave noticed that a test we did in ipv6_add_addr to see if we next hop route for the interface we're adding an addres to was wrong (see commit 7ffbcecbeed91e5874e9a1cfc4c0cbb07dac3069). for one, it never triggers, and two, it was completely wrong to begin with. This test was meant to cover this section of RFC 4429: 3.3 Modifications to RFC 2462 Stateless Address Autoconfiguration * (modifies section 5.5) A host MAY choose to configure a new address as an Optimistic Address. A host that does not know the SLLAO of its router SHOULD NOT configure a new address as Optimistic. A router SHOULD NOT configure an Optimistic Address. This patch should bring us into proper compliance with the above clause. Since we only add a SLAAC address after we've received a RA which may or may not contain a source link layer address option, we can pass a pointer to that option to addrconf_prefix_rcv (which may be null if the option is not present), and only set the optimistic flag if the option was found in the RA. Change notes: (v2) modified the new parameter to addrconf_prefix_rcv to be a bool rather than a pointer to make its use more clear as per request from davem.

A simplified version of the semantic match that finds the problem is as follows: (http://coccinelle.lip6.fr) // <smpl> @r exists@ local idexpression x; statement S; identifier f1; position p1,p2; expression *ptr != NULL; @@ x@p1 = \(kmalloc\|kzalloc\|kcalloc\)(...); ... if (x == NULL) S <... when != x when != if (...) { <+...x...+> } x->f1 ...> ( return \(0\|<+...x...+>\|ptr\); | return@p2 ...; ) @script:python@ p1 << r.p1; p2 << r.p2; @@ print "* file: %s kmalloc %s return %s" % (p1[0].file,p1[0].line,p2[0].line) // </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Signed-off-by: John W.

2012-01-04mac80211: always clear SDATA_STATE_OFFCHANNEL flagEliad Peller
If the vif is stopped while it is offchannel (e.g. right after p2p negotiation) the SDATA_STATE_OFFCHANNEL flag is never get cleared, resulting in various bad effects (e.g. GO can't start beaconing).

2012-01-04cfg80211: relicense reg.c reg.h and genregdb.awk to ISCLuis R. Rodriguez
Following the tradition we have had with ath5k, ath9k, CRDA, wireless-regdb I'd like to license this code under the permissive ISC license for the code sharing purposes with other OSes, it'd sure be nice to help the landscape in this area. Although I am %82.89 owner of the regulatory code I have asked every contributor to the regulatory code and have receieved positive Acked-bys from everyone except two deceased entities: o Frans Pop RIP 2010 [0] - Frans Pop <elendil@planet.nl> - Frans Pop <fjp@debian.org> o Nokia RIP February, 11, 2011 [1], [2] - ext-yuri.ershov@nokia.com - kalle.valo@nokia.com Frans Pop's contribution was a simple patch 55f98938, titled, "wireless: remove trailing space in messages" which just add a \n to some printk lines. I'm going to treat these additions as uncopyrightable. As for the contributions made by employees on behalf of Nokia my contact point was Petri Karhula <petri.karhula@nokia.com> but after one month he noted he had not been able to get traction from the legal department on this request, as such it I proceeded by replacing their contributions in previous patches. The end goal is to help a clean rewrite that starts in userspace that is shared under ISC license which currently is taking place with the regulatory simulator [3].

2012-01-04net_sched: sfq: always randomize hash perturbationEric Dumazet
SFQ q->perturbation is used in sfq_hash() as an input to Jenkins hash. We currently randomize this 32bit value only if a perturbation timer is setup. Its much better to always initialize it to defeat attackers, or else they can predict very well what kind of packets they have to forge to hit a particular flow.

Since commit 817fb15dfd98 (net_sched: sfq: allow divisor to be a parameter), we can leave perturbation timer armed if a memory allocation error aborts sfq_init(). Memory containing active struct timer_list is freed and kernel can crash. Call sfq_destroy() from sfq_init() to properly dismantle qdisc.

2012-01-04ethtool: Allow drivers to select RX NFC rule locationsBen Hutchings
Define special location values for RX NFC that request the driver to select the actual rule location. This allows for implementation on devices that use hash-based filter lookup, whereas currently the API is more suited to devices with TCAM lookup or linear search. In ethtool_set_rxnfc() and the compat wrapper ethtool_ioctl(), copy the structure back to user-space after insertion so that the actual location is returned.
