git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm Pull ACPI power management fix from Rafael Wysocki: "This is just a one-liner fixing a regression introduced in 3.13 that broke system suspend on some Chromebooks. On those machines there are ACPI device objects for some I2C devices that can wake up the system from sleep states, but that is done via a platform-specific mechanism and the ACPI objects don't contain any wakeup-related information. When we started to use ACPI power management with those devices (which happened during the 3.13 cycle), their configuration confused the ACPI PM layer that returned error codes from suspend callbacks for them causing system suspend to fail. However, the ACPI PM layer can safely ignore the wakeup setting from a device driver if the ACPI object corresponding to the device in question doesn't contain wakeup information in which case the driver itself is responsible for setting up the device for system wakeup" * tag 'pm+acpi-3.18-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: ACPI / PM: Ignore wakeup setting if the ACPI companion can't wake up

2014-11-21tcp: Restore RFC5961-compliant behavior for SYN packetsCalvin Owens1-2/+2
Commit c3ae62af8e755 ("tcp: should drop incoming frames without ACK flag set") was created to mitigate a security vulnerability in which a local attacker is able to inject data into locally-opened sockets by using TCP protocol statistics in procfs to quickly find the correct sequence number. This broke the RFC5961 requirement to send a challenge ACK in response to spurious RST packets, which was subsequently fixed by commit 7b514a886ba50 ("tcp: accept RST without ACK flag"). Unfortunately, the RFC5961 requirement that spurious SYN packets be handled in a similar manner remains broken. RFC5961 section 4 states that: ... the handling of the SYN in the synchronized state SHOULD be performed as follows: 1) If the SYN bit is set, irrespective of the sequence number, TCP MUST send an ACK (also referred to as challenge ACK) to the remote peer: <SEQ=SND.NXT><ACK=RCV.NXT><CTL=ACK> After sending the acknowledgment, TCP MUST drop the unacceptable segment and stop processing further. By sending an ACK, the remote peer is challenged to confirm the loss of the previous connection and the request to start a new connection. A legitimate peer, after restart, would not have a TCB in the synchronized state. Thus, when the ACK arrives, the peer should send a RST segment back with the sequence number derived from the ACK field that caused the RST. This RST will confirm that the remote peer has indeed closed the previous connection. Upon receipt of a valid RST, the local TCP endpoint MUST terminate its connection. The local TCP endpoint should then rely on SYN retransmission from the remote end to re-establish the connection. This patch lets SYN packets through the discard added in c3ae62af8e755, so that spurious SYN packets are properly dealt with as per the RFC. The challenge ACK is sent unconditionally and is rate-limited, so the original vulnerability is not reintroduced by this patch.

2014-11-21ARM: 8216/1: xscale: correct auxiliary register in suspend/resumeDmitry Eremin-Solenikov1-2/+2

2014-11-20ipx: fix locking regression in ipx_sendmsg and ipx_recvmsgJiri Bohac1-1/+5
This fixes an old regression introduced by commit b0d0d915 (ipx: remove the BKL). When a recvmsg syscall blocks waiting for new data, no data can be sent on the same socket with sendmsg because ipx_recvmsg() sleeps with the socket locked. This breaks mars-nwe (NetWare emulator): - the ncpserv process reads the request using recvmsg - ncpserv forks and spawns nwconn - ncpserv calls a (blocking) recvmsg and waits for new requests - nwconn deadlocks in sendmsg on the same socket Commit b0d0d915 has simply replaced BKL locking with lock_sock/release_sock. Unlike now, BKL got unlocked while sleeping, so a blocking recvmsg did not block a concurrent sendmsg. Only keep the socket locked while actually working with the socket data and release it prior to calling skb_recv_datagram().

2014-11-20thermal: cpu_cooling: Update always cpufreq policy with thermal constraintsYadwinder Singh Brar1-16/+21
Existing code updates cupfreq policy only while executing cpufreq_apply_cooling() function (i.e. when notify_device != NOTIFY_INVALID). It doesn't apply constraints when cpufreq policy update happens from any other place but it should update the cpufreq policy with thermal constraints every time when there is a cpufreq policy update, to keep state of cpufreq_cooling_device and max_feq of cpufreq policy in sync. For instance while resuming cpufreq updates cpufreq_policy and it restores default policy->usr_policy values irrespective of cooling device's cpufreq_state since notification gets missed because (notify_device == NOTIFY_INVALID). Another problem, is that userspace is able to change max_freq irrespective of cooling device's state, as notification gets missed. This patch modifies code to maintain a global cpufreq_dev_list and applies constraints of all matching cooling devices for policy's cpu when there is any policy update(ends up applying the lowest max_freq among the matching cpu cooling devices). This patch also removes redundant check (max_freq > policy->user_policy.max), as cpufreq framework takes care of user_policy constraints already where ever required, otherwise its causing an issue while increasing max_freq in normal scenerio as it restores max_freq with policy->user_policy.max which is old (smaller) value.

2014-11-20ufs: fix power info after link start-upYaniv Gardi1-0/+18
After link start-up power mode will always be PWM G1. This is not reflected in the pwr_info struct which will keep the previous values. Since ufshcd_change_power_mode() tries to avoid unnecessary power mode change if the requested power mode and current power mode are same, power mode change won't execute again after driver initialization. This patch solves the problem by setting pwr_info to PWM G1 after link start-up.

2014-11-20ufs: fix reference counting of W-LUsAkinobu Mita2-40/+36
UFS driver adds three well known LUs in the initialization, but those reference counts are not decremented, so it makes ufshcd module impossible to unload. This fixes it by putting scsi_device_put() in the initalization, and in order to protect concurrent access to hba->sdev_ufs_device (UFS Device W-LU) from manual delete, increment the reference count while requesting device power mode setting. The rest of W-LUs (hba->sdev_boot and hba->sdev_rpmb) are not directly used from driver, so these references in struct ufs_hba are removed.

2014-11-20bnx2fc: do not add shared skbs to the fcoe_rx_listMaurizio Lombardi1-0/+7
In some cases, the fcoe_rx_list may contains multiple instances of the same skb (the so called "shared skbs"). the bnx2fc_l2_rcv thread is a loop that extracts a skb from the list, modifies (and destroys) its content and then proceed to the next one. The problem is that if the skb is shared, the remaining instances will be corrupted. The solution is to use skb_share_check() before adding the skb to the fcoe_rx_list.

2014-11-20ovl: fix race in private xattr checksMiklos Szeredi1-9/+18
Xattr operations can race with copy up. This does not matter as long as we consistently fiter out "trunsted.overlay.opaque" attribute on upper directories. Previously we checked parent against OVL_PATH_MERGE. This is too general, and prone to race with copy-up. I.e. we found the parent to be on the lower layer but ovl_dentry_real() would return the copied-up dentry, possibly with the "opaque" attribute. So instead use ovl_path_real() and decide to filter the attributes based on the actual type of the dentry we'll use. Signed-off-by: Miklos Szeredi <[email protected]>
2014-11-20ovl: fix remove/copy-up raceMiklos Szeredi1-12/+19
ovl_remove_and_whiteout() needs to check if upper dentry exists or not after having locked upper parent directory. Previously we used a "type" value computed before locking the upper parent directory, which is susceptible to racing with copy-up. There's a similar check in ovl_check_empty_and_clear(). This one is not actually racy, since copy-up doesn't change the "emptyness" property of a directory. Add a comment to this effect, and check the existence of upper dentry locally to make the code cleaner. Signed-off-by: Miklos Szeredi <[email protected]>
