2018-07-21signal: Use PIDTYPE_TGID to clearly store where file signals will be sentEric W. Biederman
When f_setown is called a pid and a pid type are stored. Replace the use of PIDTYPE_PID with PIDTYPE_TGID as PIDTYPE_TGID goes to the entire thread group. Replace the use of PIDTYPE_MAX with PIDTYPE_PID as PIDTYPE_PID now is only for a thread. Update the users of __f_setown to use PIDTYPE_TGID instead of PIDTYPE_PID. For now the code continues to capture task_pid (when task_tgid would really be appropriate), and iterate on PIDTYPE_PID (even when type == PIDTYPE_TGID) out of an abundance of caution to preserve existing behavior. Oleg Nesterov suggested using the test to ensure we use PIDTYPE_PID for tgid lookup also be used to avoid taking the tasklist lock.

Daniel Borkmann says: ==================== pull-request: bpf-next 2018-07-20 The following pull-request contains BPF updates for your *net-next* tree. The main changes are: 1) Add sharing of BPF objects within one ASIC: this allows for reuse of the same program on multiple ports of a device, and therefore gains better code store utilization. On top of that, this now also enables sharing of maps between programs attached to different ports of a device, from Jakub. 2) Cleanup in libbpf and bpftool's Makefile to reduce unneeded feature detections and unused variable exports, also from Jakub. 3) First batch of RCU annotation fixes in prog array handling, i.e. there are several __rcu markers which are not correct as well as some of the RCU handling, from Roman. 4) Two fixes in BPF sample files related to checking of the prog_cnt upper limit from sample loader, from Dan. 5) Minor cleanup in sockmap to remove a set but not used variable, from Colin. ==================== Signed-off-by: David S.

2018-07-19net-next/hinic: fix a problem in hinic_xmit_frame()Zhao Chen
The calculation of "wqe_size" is not correct when the tx queue is busy in hinic_xmit_frame(). When there are no free WQEs, the tx flow will unmap the skb buffer, then ring the doobell for the pending packets. But the "wqe_size" which used to calculate the doorbell address is not correct. The wqe size should be cleared to 0, otherwise, it will cause a doorbell error. This patch fixes the problem.

2018-07-18net/mlx5: Adjust clock overflow work periodAriel Levkovich
When driver converts HW timestamp to wall clock time it subtracts the last saved cycle counter from the HW timestamp and converts the difference to nanoseconds. The conversion is done by multiplying the cycles difference with the clock multiplier value as a first step and therefore the cycles difference should be small enough so that the multiplication product doesn't exceed 64bit. The overflow handling routine is in charge of updating the last saved cycle counter in driver and it is called periodically using kernel delayed workqueue. The delay period for this work is calculated using the max HW cycle counter value (a 41 bit mask) as a base which doesn't take the 64bit limit into account so the delay period may be incorrect and too long to prevent a large difference between the HW counter and the last saved counter in SW. This change adjusts the work period for the HW clock overflow work by taking the minimum between the previous value and the quotient of max u64 value and the clock multiplier value.

2018-07-18net: cxgb3_main: fix potential Spectre v1Gustavo A. R. Silva
t.qset_idx can be indirectly controlled by user-space, hence leading to a potential exploitation of the Spectre variant 1 vulnerability. This issue was detected with the help of Smatch: drivers/net/ethernet/chelsio/cxgb3/cxgb3_main.c:2286 cxgb_extension_ioctl() warn: potential spectre issue 'adapter->msix_info' Fix this by sanitizing t.qset_idx before using it to index adapter->msix_info Notice that given that speculation windows are large, the policy is to kill the speculation on the first load and not worry if it can be completed with a dependent load/store [1].

2018-07-19mlxsw: spectrum_acl: Add region association callbackIdo Schimmel
In Spectrum-2, ACL regions that use 8 or 12 key blocks require several consecutive hardware regions. In order to allow defragmentation, the device stores a mapping from a logical region ID to an hardware region ID, which is similar to the page table that is used to translate virtual addresses to physical addresses. Add the region association callback to the region create sequence and implement it as a NOP in Spectrum which does not require it.
