2013-03-19ipvs: remove extra rcu lockJulian Anastasov1-2/+0
In 3.7 we added code that uses ipv4_update_pmtu but after commit c5ae7d4192 (ipv4: must use rcu protection while calling fib_lookup) the RCU lock is not needed. Signed-off-by: Julian Anastasov <ja@ssi.bg> Signed-off-by: Simon Horman <horms@verge.net.au>
2013-03-19ipvs: add backup_only flag to avoid loopsJulian Anastasov4-4/+34
Dmitry Akindinov is reporting for a problem where SYNs are looping between the master and backup server when the backup server is used as real server in DR mode and has IPVS rules to function as director. Even when the backup function is enabled we continue to forward traffic and schedule new connections when the current master is using the backup server as real server. While this is not a problem for NAT, for DR and TUN method the backup server can not determine if a request comes from client or from director. To avoid such loops add new sysctl flag backup_only. It can be needed for DR/TUN setups that do not need backup and director function at the same time. When the backup function is enabled we stop any forwarding and pass the traffic to the local stack (real server mode). The flag disables the director function when the backup function is enabled. For setups that enable backup function for some virtual services and director function for other virtual services there should be another more complex solution to support DR/TUN mode, may be to assign per-virtual service syncid value, so that we can differentiate the requests.

2013-03-18mwifiex: fix race when queuing commandsAmitkumar Karwar4-17/+10
Running the following script repeatedly on XO-4 with SD8787 produces command timeout and system lockup. insmod mwifiex_sdio.ko sleep 1 ifconfig eth0 up iwlist eth0 scan & sleep 0.5 rmmod mwifiex_sdio mwifiex_send_cmd_async() is called for sync as well as async commands. (mwifiex_send_cmd_sync() internally calls it for sync command.) "adapter->cmd_queued" gets filled inside mwifiex_send_cmd_async() routine for both types of commands. But it is used only for sync commands in mwifiex_wait_queue_complete(). This could lead to a race when two threads try to queue a sync command with another sync/async command simultaneously. Get rid of global variable and pass command node as a parameter to mwifiex_wait_queue_complete() to fix the problem.

The commit 'ath9k_hw: fix calibration issues on chainmask that don't include chain 0' changed the hardware chainmask to the chip chainmask for the duration of the calibration, but the revert to user configuration in the reset path runs too early. That causes some issues with limiting the number of antennas (including spurious failure in hardware-generated packets). Fix this by reverting the chainmask after the essential parts of the calibration that need the workaround, and before NF calibration is run.

2013-03-18xfs: ensure we capture IO errors correctlyDave Chinner1-0/+6
Failed buffer readahead can leave the buffer in the cache marked with an error. Most callers that then issue a subsequent read on the buffer do not zero the b_error field out, and so we may incorectly detect an error during IO completion due to the stale error value left on the buffer. Avoid this problem by zeroing the error before IO submission. This ensures that the only IO errors that are detected those captured from are those captured from bio submission or completion.

2013-03-18tcp: dont handle MTU reduction on LISTEN socketEric Dumazet2-7/+14
When an ICMP ICMP_FRAG_NEEDED (or ICMPV6_PKT_TOOBIG) message finds a LISTEN socket, and this socket is currently owned by the user, we set TCP_MTU_REDUCED_DEFERRED flag in listener tsq_flags. This is bad because if we clone the parent before it had a chance to clear the flag, the child inherits the tsq_flags value, and next tcp_release_cb() on the child will decrement sk_refcnt. Result is that we might free a live TCP socket, as reported by Dormando. IPv4: Attempt to release TCP socket in state 1 Fix this issue by testing sk_state against TCP_LISTEN early, so that we set TCP_MTU_REDUCED_DEFERRED on appropriate sockets (not a LISTEN one) This bug was introduced in commit 563d34d05786 (tcp: dont drop MTU reduction indications) Reported-by: dormando <dormando@rydia.net> Signed-off-by: Eric Dumazet <edumazet@google.com> Signed-off-by: David S.

Commit 1d9d8639c063 ("perf,x86: fix kernel crash with PEBS/BTS after suspend/resume") fixed a crash when doing PEBS performance profiling after resuming, but in using init_debug_store_on_cpu() to restore the DS_AREA mtrr it also resulted in a new WARN_ON() triggering. init_debug_store_on_cpu() uses "wrmsr_on_cpu()", which in turn uses CPU cross-calls to do the MSR update. Which is not really valid at the early resume stage, and the warning is quite reasonable. Now, it all happens to _work_, for the simple reason that smp_call_function_single() ends up just doing the call directly on the CPU when the CPU number matches, but we really should just do the wrmsr() directly instead. This duplicates the wrmsr() logic, but hopefully we can just remove the wrmsr_on_cpu() version eventually.

Linville says: ==================== On the NFC bits, Samuel says: "With this one we have: - A fix for properly decreasing socket ack log. - A timer and works cleanup upon NFC device removal. - A monitoroing socket cleanup round from llcp_socket_release. - A proper error report to pending sockets upon NFC device removal." Regarding the Bluetooth bits, Gustavo says: "I have these two patches for 3.9, these add support for two more devices to the bluetooth drivers." Along with those, we have a few wireless driver fixes... Bing Zhao provides an mwifiex to prevent an out-of-bounds memory access. John Crispin offers a Kconfig fix to enable some otherwise dead code in rt2x00. The correct symbols were added in -rc1 through a different tree, but the symbols for enabling the wireless driver didn't match. Larry Finger brings an rtlwifi fix for a scheduling while atomic bug, and another fix for a reassociation problem caused by failing to clear the BSSID after a disconnect. ==================== Signed-off-by: David S.

The return value is taken into account to stop the netqork queue on the adapter in case there are no free slots. However, cpdma_check_free_tx_desc() returns 'true' if there is room in the bitmap, not 'false', so the usage of the function is wrong.

2013-03-17ethernet/tulip: DE4x5 needs VIRT_TO_BUSArnd Bergmann1-0/+1
The automated ARM build tests have shown that the tulip de4x5 driver uses the old-style virt_to_bus() interface on some architectures. Alpha, Sparc and PowerPC did not hit this problem, because they use a different code path, and most other architectures actually do provide VIRT_TO_BUS.

Disabling CONFIG_VIRT_TO_BUS on ARM showed that the hisax netjet driver depends on this deprecated functionality but is not marked so in Kconfig. Rather than adding ARM to the already long list of architectures that this driver is broken on, this patch adds 'depends on VIRT_TO_BUS' and removes the dependency on !SPARC, which is also implied by that.

2013-03-17net: cdc_ncm, cdc_mbim: allow user to prefer NCM for backwards compatibilityBjørn Mork3-27/+34
commit bd329e1 ("net: cdc_ncm: do not bind to NCM compatible MBIM devices") introduced a new policy, preferring MBIM for dual NCM/MBIM functions if the cdc_mbim driver was enabled. This caused a regression for users wanting to use NCM. Devices implementing NCM backwards compatibility according to section 3.2 of the MBIM v1.0 specification allow either NCM or MBIM on a single USB function, using different altsettings. The cdc_ncm and cdc_mbim drivers will both probe such functions, and must agree on a common policy for selecting either MBIM or NCM. Until now, this policy has been set at build time based on CONFIG_USB_NET_CDC_MBIM. Use a module parameter to set the system policy at runtime, allowing the user to prefer NCM on systems with the cdc_mbim driver.

unconditionally" This reverts commit 412ed94744d16806fbec3bd250fd94e71cde5a1f. The commit is wrong as tiph points to the outer IPv4 header which is installed at ipgre_header() and not the inner one which is protocol dependant. This commit broke succesfully opennhrp which use PF_PACKET socket with ETH_P_NHRP protocol. Additionally ssl_addr is set to the link-layer IPv4 address. This address is written by ipgre_header() to the skb earlier, and this is the IPv4 header tiph should point to - regardless of the inner protocol payload.
