| | * tcp: Reject invalid ack_seq to Fast Open socketsJerry Chu2012-10-232-4/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A packet with an invalid ack_seq may cause a TCP Fast Open socket to switch to the unexpected TCP_CLOSING state, triggering a BUG_ON kernel panic. When a FIN packet with an invalid ack_seq# arrives at a socket in the TCP_FIN_WAIT1 state, rather than discarding the packet, the current code will accept the FIN, causing state transition to TCP_CLOSING. This may be a small deviation from RFC793, which seems to say that the packet should be dropped. Unfortunately I did not expect this case for Fast Open hence it will trigger a BUG_ON panic. It turns out there is really nothing bad about a TFO socket going into TCP_CLOSING state so I could just remove the BUG_ON statements. But after some thought I think it's better to treat this case like TCP_SYN_RECV and return a RST to the confused peer who caused the unacceptable ack_seq to be generated in the first place.

So IPsec + IP defrag/reassembly (using skb coalescing), or TCP coalescing could leak secpath objects. Fix this bug by calling skb_release_head_state(skb) to properly release all possible references to linked objects.

Fix this, while avoiding the "Korean AP" issue by disabling HT40 and advertising HT20 to the AP when connecting.

Fix this and to mask the correct fields. While doing so, convert the code to mask the full FC using IEEE80211_FCTL_* defines similarly to how CCMP AAD is built. Since BIP is used only with broadcast/multicast management frames, the Retry field is always 0 in these frames. The Protected field is also zero to maintain backwards compatibility. As such, the incorrect mask here does not really cause any problems for valid frames. In theory, an invalid BIP frame with Retry or Protected field set to 1 could be rejected because of BIP validation. However, no such frame should show up with standard compliant implementations, so this does not cause problems in normal BIP use.

It appears netlink_release() should use kfree_rcu() instead of kfree() for the listeners structure as it may be used by other cpus using RCU protection. netlink_release() must set to NULL the listeners pointer when it is about to be freed. Also have to protect netlink_update_listeners() and netlink_has_listeners() if listeners is NULL. Add a nl_deref_protected() lockdep helper to properly document which locks protects us.

Basically, Chris has shown that in certain circumstances, the call to xs_error_report causes the rpc_task that is responsible for reconnecting to wake up early, thus triggering a disconnect and retry. Since the sk->sk_error_report() calls in the socket layer are always followed by a tcp_done() in the cases where we care about waking up the rpc_tasks, just let the state_change callbacks take responsibility for those wake ups.

This is done with the provision of two new key type operations: int (*preparse)(struct key_preparsed_payload *prep); void (*free_preparse)(struct key_preparsed_payload *prep); If the first operation is present, then it is called before key creation (in the add/update case) or before the key semaphore is taken (in the update and instantiate cases). The second operation is called to clean up if the first was called. preparse() is given the opportunity to fill in the following structure: struct key_preparsed_payload { char *description; void *type_data[2]; void *payload; const void *data; size_t datalen; size_t quotalen; }; Before the preparser is called, the first three fields will have been cleared, the payload pointer and size will be stored in data and datalen and the default quota size from the key_type struct will be stored into quotalen. The preparser may parse the payload in any way it likes and may store data in the type_data[] and payload fields for use by the instantiate() and update() ops. The preparser may also propose a description for the key by attaching it as a string to the description field. This can be used by passing a NULL or "" description to the add_key() system call or the key_create_or_update() function. This cannot work with request_key() as that required the description to tell the upcall about the key to be created. This, for example permits keys that store PGP public keys to generate their own name from the user ID and public key fingerprint in the key. The instantiate() and update() operations are then modified to look like this: int (*instantiate)(struct key *key, struct key_preparsed_payload *prep); int (*update)(struct key *key, struct key_preparsed_payload *prep); and the new payload data is passed in *prep, whether or not it was preparsed.

There was some progress on my remaining 4.1 todo's, but a couple of them were just of the form "check that we do X correctly", so didn't have much affect on the code. Other than that, a bunch of cleanup and some bugfixes (including an annoying NFSv4.0 state leak and a busy-loop in the server that could cause it to peg the CPU without making progress)." * 'for-3.7' of git://linux-nfs.org/~bfields/linux: (46 commits) UAPI: (Scripted) Disintegrate include/linux/sunrpc UAPI: (Scripted) Disintegrate include/linux/nfsd nfsd4: don't allow reclaims of expired clients nfsd4: remove redundant callback probe nfsd4: expire old client earlier nfsd4: separate session allocation and initialization nfsd4: clean up session allocation nfsd4: minor free_session cleanup nfsd4: new_conn_from_crses should only allocate nfsd4: separate connection allocation and initialization nfsd4: reject bad forechannel attrs earlier nfsd4: enforce per-client sessions/no-sessions distinction nfsd4: set cl_minorversion at create time nfsd4: don't pin clientids to pseudoflavors nfsd4: fix bind_conn_to_session xdr comment nfsd4: cast readlink() bug argument NFSD: pass null terminated buf to kstrtouint() nfsd: remove duplicate init in nfsd4_cb_recall nfsd4: eliminate redundant nfs4_free_stateid fs/nfsd/nfs4idmap.c: adjust inconsistent IS_ERR and PTR_ERR ...

After these patches, userspace headers will be segregated into: include/uapi/linux/.../foo.h for the userspace interface stuff, and: include/linux/.../foo.h for the strictly kernel internal stuff.

In theory you can also remove listening sockets this way. But nobody's ever done that as far as I can tell. Also this was partially broken in 2.6.25, by a217813f9067b785241cb7f31956e51d2071703a "knfsd: Support adding transports by writing portlist file". (Note that we decide whether to take the "delfd" case by checking for a digit--but what's actually expected in that case is something made by svc_one_sock_name(), which won't begin with a digit.) So, let's just rip out this stuff. Acked-by: NeilBrown <neilb@suse.de> Signed-off-by: J. Bruce Fields <bfields@redhat.com>
