For IPv6, sizeof(struct ipv6hdr) = 40, thus the following expression will result negative: datalen = pkt_dev->cur_pkt_size - 14 - sizeof(struct ipv6hdr) - sizeof(struct udphdr) - pkt_dev->pkt_overhead; And, the check "if (datalen < sizeof(struct pktgen_hdr))" will be passed as "datalen" is promoted to unsigned, therefore will cause a crash later. This is a quick fix by checking if "datalen" is negative. The following patch will increase the default value of 'min_pkt_size' for IPv6. This bug should exist for a long time, so Cc -stable too.

John W. Linville says: ==================== Here is a batch of fixes intended for 3.7... Amitkumar Karwar provides a couple of mwifiex fixes to correctly report some reason codes for certain connection failures. He also provides a fix to cleanup after a scanning failure. Bing Zhao rounds that out with another mwifiex scanning fix. Daniel Golle gives us a fix for a copy/paste error in rt2x00. Felix Fietkau brings a couple of ath9k fixes related to suspend/resume, and a couple of fixes to prevent memory leaks in ath9k and mac80211. Ronald Wahl sends a carl9170 fix for a sleep in softirq context. Thomas Pedersen reorders some code to prevent drv_get_tsf from being called while holding a spinlock, now that it can sleep. Finally, Wei Yongjun prevents a NULL pointer dereference in the ath5k driver. Please let me know if there are problems! ==================== Signed-off-by:

Pull pwm changes from Thierry Reding: "All legacy PWM providers have now been moved to the PWM subsystem. The plan for 3.8 is to adapt all board files to provide a lookup table for PWM devices in order to get rid of the global namespace. Subsequently, users of the legacy pwm_request() and pwm_free() functions can be migrated to the new pwm_get() and pwm_put() functions. Once this has been completed, the legacy API and the compatibility code in the core can be removed. In addition to the above, these changes also add support for configuring the polarity of a PWM signal (currently only supported on ECAP and EHRPWM) and include a much needed rework of the i.MX driver. Managed functions to obtain and release a PWM device (devm_pwm_get() and devm_pwm_put()) have been added and the pwm-backlight driver has been updated to use them. If the PWM subsystem hasn't been enabled, dummy functions are provided that allow the subsystem to safely compile out. Some common checks on input parameters have been moved to the core and removed from the drivers. Finally, a small fix corrects the description of the PWM specifier's second cell in the device tree representation." * tag 'for-3.7-rc1' of git://gitorious.org/linux-pwm/linux-pwm: (23 commits) pwm: dt: Fix description of second PWM cell pwm: Check for negative duty-cycle and period pwm: Add Ingenic JZ4740 support MIPS: JZ4740: Export timer API pwm: Move PUV3 PWM driver to PWM framework unicore32: pwm: Use managed resource allocations unicore32: pwm: Remove unnecessary indirection unicore32: pwm: Use module_platform_driver() unicore32: pwm: Properly remap memory-mapped registers pwm-backlight: Use devm_pwm_get() instead of pwm_get() pwm: Move AB8500 PWM driver to PWM framework pwm: Fix compilation error when CONFIG_PWM is not defined pwm: i.MX: fix clock lookup pwm: i.MX: use per clock unconditionally pwm: i.MX: add devicetree support pwm: i.MX: Use module_platform_driver pwm: i.MX: add functions to enable/disable pwm. pwm: i.MX: remove unnecessary if in pwm_[en|dis]able pwm: i.MX: factor out SoC specific functions pwm: pwm-tiehrpwm: Add support for configuring polarity of PWM ...

This is the revised patch for fixing rds-ping spinlock recursion according to Venkat's suggestions. RDS ping/pong over TCP feature has been broken for years(2.6.39 to 3.6.0) since we have to set TCP cork and call kernel_sendmsg() between ping/pong which both need to lock "struct sock *sk". However, this lock has already been hold before rds_tcp_data_ready() callback is triggerred. As a result, we always facing spinlock resursion which would resulting in system panic. Given that RDS ping is only used to test the connectivity and not for serious performance measurements, we can queue the pong transmit to rds_wq as a delayed response. Reported-by:

Fengguang reported a kernel build failure as following: drivers/built-in.o: In function `pch_gbe_ioctl': pch_gbe_main.c:(.text+0x510370): undefined reference to `pch_ch_control_write' pch_gbe_main.c:(.text+0x510393): undefined reference to `pch_ch_control_write' pch_gbe_main.c:(.text+0x5103b3): undefined reference to `pch_ch_control_write' ... It's a regression by commit da158646. The root cause is that the CONFIG_PPS is not set there, consequently CONFIG_PTP_1588_CLOCK can not be set anyway, which finally causes ptp_pch and pch_gbe_main build failures. As David prefers to use *select* to fix such module co-dependency issues, this patch explicitly selects all the possible dependencies of PCH_PTP. Reported-by:
