| * ipv6: move dereference after check in fl_free()Dan Carpenter2012-08-16
| | | | | | | | | | | | | | | | | | There is a dereference before checking for NULL bug here. Generally free() functions should accept NULL pointers. For example, fl_create() can pass a NULL pointer to fl_free() on the error path. Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com> Signed-off-by: Eric W. Biederman <ebiederm@xmission.com>

| * userns: Convert xt_LOG to print socket kuids and kgids as uids and gidsEric W. Biederman2012-08-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | xt_LOG always writes messages via sb_add via printk. Therefore when xt_LOG logs the uid and gid of a socket a packet came from the values should be converted to be in the initial user namespace. Thus making xt_LOG as user namespace safe as possible.

| * userns: Convert cls_flow to work with user namespaces enabledEric W. Biederman2012-08-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The flow classifier can use uids and gids of the sockets that are transmitting packets and do insert those uids and gids into the packet classification calcuation. I don't fully understand the details but it appears that we can depend on specific uids and gids when making traffic classification decisions. To work with user namespaces enabled map from kuids and kgids into uids and gids in the initial user namespace giving raw integer values the code can play with and depend on. To avoid issues of userspace depending on uids and gids in packet classifiers installed from other user namespaces and getting confused deny all packet classifiers that use uids or gids that are not comming from a netlink socket in the initial user namespace.

| * net sched: Pass the skb into change so it can access NETLINK_CBEric W. Biederman2012-08-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | cls_flow.c plays with uids and gids. Unless I misread that code it is possible for classifiers to depend on the specific uid and gid values. Therefore I need to know the user namespace of the netlink socket that is installing the packet classifiers. Pass in the rtnetlink skb so I can access the NETLINK_CB of the passed packet. In particular I want access to sk_user_ns(NETLINK_CB(in_skb).ssk). Pass in not the user namespace but the incomming rtnetlink skb into the the classifier change routines as that is generally the more useful parameter.

| * userns: nfnetlink_log: Report socket uids in the log sockets user namespaceEric W. Biederman2012-08-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | At logging instance creation capture the peer netlink socket's user namespace. Use the captured peer user namespace when reporting socket uids to the peer. The peer socket's user namespace is guaranateed to be valid until the user closes the netlink socket. nfnetlink_log removes instances during the final close of a socket. __build_packet_message does not get called after an instance is destroyed. Therefore it is safe to let the peer netlink socket take care of the user namespace reference counting for us. Acked-by: David S.

| * netlink: Make the sending netlink socket availabe in NETLINK_CBEric W. Biederman2012-08-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The sending socket of an skb is already available by it's port id in the NETLINK_CB. If you want to know more like to examine the credentials on the sending socket you have to look up the sending socket by it's port id and all of the needed functions and data structures are static inside of af_netlink.c. So do the simple thing and pass the sending socket to the receivers in the NETLINK_CB. I intend to use this to get the user namespace of the sending socket in inet_diag so that I can report uids in the context of the process who opened the socket, the same way I report uids in the contect of the process who opens files.

| * net ip6 flowlabel: Make owner a union of struct pid * and kuid_tEric W. Biederman2012-08-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Correct a long standing omission and use struct pid in the owner field of struct ip6_flowlabel when the share type is IPV6_FL_S_PROCESS. This guarantees we don't have issues when pid wraparound occurs. Use a kuid_t in the owner field of struct ip6_flowlabel when the share type is IPV6_FL_S_USER to add user namespace support. In /proc/net/ip6_flowlabel capture the current pid namespace when opening the file and release the pid namespace when the file is closed ensuring we print the pid owner value that is meaning to the reader of the file. Similarly use from_kuid_munged to print uid values that are meaningful to the reader of the file. This requires exporting pid_nr_ns so that ipv6 can continue to built as a module.

For now however start simply and do a straight forward conversion I can be certain is correct. In cred_to_ucred use from_kuid_munged and from_kgid_munged as these values are going directly to userspace and we want to use the userspace safe values not -1 when reporting a value that does not map.

| | | | | | | | | | | | | | | | | | | | The user namespace code has an explicit "depends on USB_DEVICEFS = n" dependency to prevent building code that is not yet user namespace safe. With the removal of usbfs from the kernel it is now impossible to satisfy the USB_DEFICEFS = n dependency and thus it is impossible to enable user namespace support in 3.5-rc1.

In particular, changes to efx_nic::state are documented as serialised by the RTNL lock, but they aren't. 1. We check whether a reset was requested during probe (suggesting broken hardware) before we allow requested resets to be scheduled. This leaves a window where a requested reset would be deferred indefinitely. 2. Although we cancel the reset work item during device removal, there are still later operations that can cause it to be scheduled again. We need to check the state before scheduling it. 3. Since the state can change between scheduling and running of the work item, we still need to check it there, and we need to do so *after* acquiring the RTNL lock which serialises state changes. 4. We must cancel the reset work item during device removal, if the state could ever have been READY. This wasn't done in some of the failure paths from efx_pci_probe(). Move the cancellation to efx_pci_remove_main(). Signed-off-by: Ben Hutchings <bhutchings@solarflare.com>

Since efx_start_all() is a no-op when the NIC is disabled, this is probably harmless in the case of efx_change_mtu(), but efx_realloc_channels() also reenables interrupts which could be a bad thing to do. Change efx_start_all() and efx_start_interrupts() to assert that the NIC is not disabled, but make efx_stop_interrupts() do nothing if the NIC is disabled (since it is already stopped), consistent with efx_stop_all(). Update comments for efx_start_all() and efx_stop_all() to describe their purpose and preconditions more accurately.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | TSO header buffers contain a control structure immediately followed by the packet headers, and are kept on a free list when not in use. This complicates buffer management and tends to result in cache read misses when we recycle such buffers (particularly if DMA-coherent memory requires caches to be disabled). Replace the free list with a simple mapping by descriptor index. We know that there is always a payload descriptor between any two descriptors with TSO header buffers, so we can allocate only one such buffer for each two descriptors. While we're at it, use a standard error code for allocation failure, not -1. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit mac80211: avoid using synchronize_rcu in ieee80211_set_probe_resp changed the return value when the probe response template is not present. Revert to the earlier value of 1 - this fixes AP mode for drivers like ath9k. Signed-off-by: Sujith Manoharan <c_manoha@qca.qualcomm.com> Signed-off-by: Johannes Berg <johannes.berg@intel.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This reverts commit 2e48928d8a0f38c1b5c81eb3f1294de8a6382c68. Those functions are needed and should not be removed, or there is no way to set the rfkill led trigger name.
