For the iwlwifi one, Emmanuel says: "As explicitly written in the commit message, we prefer to disable Tx AMPDU on NICs supported by iwldvm. This feature gives a big boost in Tx performance, but the firmware is buggy and we can't rely on it. Our hope is that most of the users out there want wifi to surf on the web which means that they care more for Rx traffic than for Tx. People who want to enable it can do so with the help of a module parameter." On top of that... Dan Carpenter fixes a typo/thinko in ath5k. Olivier Langlois fixes a couple of rtlwifi issues, one which leaves IRQs disabled too long (causing a variety of problems elsewhere), and one which fixes an incorrect return code when failing to enable the NIC.

2014-02-18net: sctp: fix sctp_connectx abi for ia32 emulation/compat modeDaniel Borkmann1-9/+32
SCTP's sctp_connectx() abi breaks for 64bit kernels compiled with 32bit emulation (e.g. ia32 emulation or x86_x32). Due to internal usage of 'struct sctp_getaddrs_old' which includes a struct sockaddr pointer, sizeof(param) check will always fail in kernel as the structure in 64bit kernel space is 4bytes larger than for user binaries compiled in 32bit mode. Thus, applications making use of sctp_connectx() won't be able to run under such circumstances. Introduce a compat interface in the kernel to deal with such situations by using a 'struct compat_sctp_getaddrs_old' structure where user data is copied into it, and then sucessively transformed into a 'struct sctp_getaddrs_old' structure with the help of compat_ptr(). That fixes sctp_connectx() abi without any changes needed in user space, and lets the SCTP test suite pass when compiled in 32bit and run on 64bit kernels.

2014-02-18netfilter: ctnetlink: force null nat binding on insertPablo Neira Ayuso2-42/+49
Quoting Andrey Vagin: When a conntrack is created by kernel, it is initialized (sets IPS_{DST,SRC}_NAT_DONE_BIT bits in nf_nat_setup_info) and only then it is added in hashes (__nf_conntrack_hash_insert), so one conntract can't be initialized from a few threads concurrently. ctnetlink can add an uninitialized conntrack (w/o IPS_{DST,SRC}_NAT_DONE_BIT) in hashes, then a few threads can look up this conntrack and start initialize it concurrently. It's dangerous, because BUG can be triggered from nf_nat_setup_info. Fix this race by always setting up nat, even if no CTA_NAT_ attribute was requested before inserting the ct into the hash table. In absence of CTA_NAT_ attribute, a null binding is created. This alters current behaviour: Before this patch, the first packet matching the newly injected conntrack would be run through the nat table since nf_nat_initialized() returns false. IOW, this forces ctnetlink users to specify the desired nat transformation on ct creation time. Thanks for Florian Westphal, this patch is based on his original patch to address this problem, including this patch description.

2014-02-17FS-Cache: Handle removal of unadded object to the fscache_object_list rb treeDavid Howells2-0/+8
When FS-Cache allocates an object, the following sequence of events can occur: -->fscache_alloc_object() -->cachefiles_alloc_object() [via cache->ops->alloc_object] <--[returns new object] -->fscache_attach_object() <--[failed] -->cachefiles_put_object() [via cache->ops->put_object] -->fscache_object_destroy() -->fscache_objlist_remove() -->rb_erase() to remove the object from fscache_object_list. resulting in a crash in the rbtree code. The problem is that the object is only added to fscache_object_list on the success path of fscache_attach_object() where it calls fscache_objlist_add(). So if fscache_attach_object() fails, the object won't have been added to the objlist rbtree. We do, however, unconditionally try to remove the object from the tree.

If directory is fragmented, readdir() read its dirfrags one by one. After reading all dirfrags, the corresponding dentries are sorted in (frag_t, off) order in the dcache. If dentries of a directory are all cached, __dcache_readdir() can use the cached dentries to satisfy readdir syscall.

2014-02-17ceph: add acl, noacl options for cephfs mountSage Weil1-4/+28
Make the 'acl' option dependent on having ACL support compiled in. Make the 'noacl' option work even without it so that one can always ask it to be off and not error out on mount when it is not supported.

2014-02-17ceph: fix ceph_set_acl()Yan, Zheng1-5/+1
If acl is equivalent to file mode permission bits, ceph_set_acl() needs to remove any existing acl xattr. Use __ceph_setxattr() to handle both setting and removing acl xattr cases, it doesn't return -ENODATA when there is no acl xattr. Signed-off-by: Yan, Zheng <[email protected]>
