we have two processes to do: P1#: ifconfig eth0 down; which will call bnx2_close, then will , and set Null to stats_blk P2#: ifconfig eth0; which will call bnx2_get_stats64, it will use stats_blk. In one case: --P1#-- --P2#-- stats_blk(no null) bnx2_free_mem ->bp->stats_blk = NULL GET_64BIT_NET_STATS then it will cause 'NULL Pointer' Problem. it is as well with 'ethtool -S ethx'. Allocate the statistics block at probe time so that this problem is impossible Signed-off-by:Wang Weidong <wangweidong1@huawei.com> Signed-off-by:

t4_check_fw_version() can return several error codes (-EINVAL, -EBUSY, -EAGAIN). The present code sets the adapter state to UNINIT only if its an EFAULT. In all the error cases set the adapter to uninitialized state. In t4_check_fw_version() if call to t4_get_fw_version() fails, repeat the operation a few times before returning failure. Signed-off-by:

eBPF socket filter programs may see junk in 'u32 cb[5]' area, since it could have been used by protocol layers earlier. For socket filter programs used in af_packet we need to clean 20 bytes of skb->cb area if it could be used by the program. For programs attached to TCP/UDP sockets we need to save/restore these 20 bytes, since it's used by protocol layers. Remove SK_RUN_FILTER macro, since it's no longer used. Long term we may move this bpf cb area to per-cpu scratch, but that requires addition of new 'per-cpu load/store' instructions, so not suitable as a short term fix. Fixes: d691f9e8 ("bpf: allow programs to write to certain skb fields") Reported-by:

Paul Gortmaker says: ==================== make non-modular code explicitly non-modular [v2: drop m68k patches that Geert converted to modules; add one ARM driver patch ; update net-next baseline to today; switch to ARM for build testing.] In a previous merge window, we made changes to allow better delineation between modular and non-modular code in commit 0fd972a7 ("module: relocate module_init from init.h to module.h"). This allows us to now ensure module code looks modular and non-modular code does not accidentally look modular just to avoid suffering build breakage. Here we target code that is, by nature of their Makefile and/or Kconfig settings, only available to be built-in, but implicitly presenting itself as being possibly modular by way of using modular headers, macros, and functions. The goal here is to remove that illusion of modularity from these files, but in a way that leaves the actual runtime unchanged. In doing so, we remove code that has never been tested and adds no value to the tree. And we continue the process of expecting a level of consistency between the Kconfig/Makefile of code and the code in use itself. Fortuntately the net subsystem has relatively few instances, given the overall amount of code and drivers it contains. For comparison there are over 300 instances tree wide, resulting in a possible net removal of on the order of 5000 lines of unused code. Build tested on net-next from today, on ARM, since that is the arch where the one ethernet driver changed here is available. ==================== Signed-off-by:

The Kconfig currently controlling compilation of this code is: drivers/net/ethernet/ti/Kconfig:config TI_CPSW_PHY_SEL drivers/net/ethernet/ti/Kconfig: bool "TI CPSW Switch Phy sel Support" ...meaning that it currently is not being built as a module by anyone. Lets remove the couple traces of modularity so that when reading the driver there is no doubt it is builtin-only. Since module_platform_driver() uses the same init level priority as builtin_platform_driver() the init ordering remains unchanged with this commit. Also note that MODULE_DEVICE_TABLE is a no-op for non-modular code. We also delete the MODULE_LICENSE tag etc. since all that information was (or is now) contained at the top of the file in the comments. Cc: "David S.

We can change to one of the other priority initcalls (subsys?) at any later date, if desired. We can't remove module.h since the file uses other module related stuff even though it is not modular itself. We move the information from the MODULE_LICENSE tag to the top of the file, since that information is not captured anywhere else. The MODULE_ALIAS_NET_PF_PROTO becomes a no-op in the non modular case, so it is removed. Cc: "David S.

In preparation to handling system errors at the mlx5_core level, change the interface of cmd_work_handler to accept a 64 bit argument for the vector. This allows to encode a flag that signifies when the handler is called as a result of a driver logic that wishes to terminate commands that the hardware may not be able to terminate. Such command completions are detected at the handler and proper return status is encoded. To be able to terminate page handler commands, we make sure to set the corresponding bit in the bitmask.

Jeff Kirsher says: ==================== Intel Wired LAN Driver Updates 2015-10-08 This series contains updates to i40e and i40evf only (again). Jesse fixes an issue where the driver was issuing a WARN_ON during ring size changes because the code was cloning the rx_ring struct but not zeroing out the pointers before allocating new memory, so simply zero out the pointers. Also reduced the function call overhead by moving the interrupt enable function by moving it to the header file, which it in turn allows us to inline it. Also does a thorough job of code cleanup to fix spaces after declarations, remove unnecessary braces and breaks, remove another __func__ use and general code tidiness. Mitch adds mover verbose error messages when the number of supported VFs is reported in driver init and it different from the number reported in config space. Updated the VF driver to now detect a reset with the VF_ARQLEN register since the enable bit is cleared when the VF is reset and it stays cleared until the VF driver processes the reset and re-enables the admin queue which is more reliable than using the VFGEN_RSTAT as previously. Neerav adds parsing for CEE DCBx TLVs from the LLDP MIB since there is a need to get the CEE DesiredCfg Tx by firmware and DCB configuration Rx from peer for debug and other application purposes. Carolyn fixes a problem where the PF's Flow Director filter table would have an entry that the hardware was unable to add, when this occurs an invalid entry gets replayed and a valid one is lost. Matt fixes an issue where multiple link up messages can be logged resulting from admin queue link status timing when link properties are changed. Shannon adds the ability to control the period link polling through ethtool to be able to switch it off and on for debugging link issues. Serey explicitly assigns the enum index for each VSI type so that the PF and VF always reference to the same VSI type event if the enum lists are different. ==================== Signed-off-by:

Using VFGEN_RSTAT to detect a VF reset is an endeavor that is fraught with peril. It's entirely too easy to miss a reset because none of the bits are sticky. By the time the VF driver reads the register, the reset may have been processed and cleaned up by the PF driver, leaving the register in the same state that it was before the reset. Instead, detect a reset with the VF_ARQLEN register. When the VF is reset, the enable bit in this register is cleared, and it stays cleared until the VF driver processes the reset and re-enables the admin queue. Because we now deal with multiple registers in the reset and watchdog tasks, rename the rstat_val variable to reg_val. Change-ID: Id1df17045c0992e607da0162d31807f7fc20d199 Signed-off-by:

Ran into an issue where PF's VSI type list was different from VF's, which was resulted in different enum index. The VSI type list can be different depending on what build flag is used for PF and VF. The change is to explicitly assign enum index for each VSI type so that PF and VF always reference to the same VSI type event if the enum lists are different.

There's been some need for controlling the periodic link polling for debugging link issues. This patch enables switching it off and on through an ethtool private flag. The link poll remains on by default, but can be turned off with ethtool --set-priv-flags p261p1 LinkPolling off and later turned back on with ethtool --set-priv-flags p261p1 LinkPolling on To check the current status, use ethtool --show-priv-flags p261p1 Change-ID: I32e4ab654ff3eec90a06cf144899971b82d71c40 Signed-off-by:

This patch fixes a problem where the PF's fdir filter table would have an entry that the hw was unable to add. This notification happens in the hot path, so instead of trying to fix it then, we note the location in the failure case and delete it during regular fdir subtask callback. Without this patch, a case can occur where an invalid entry gets replayed and a valid one is not. Change-ID: I67831c183b5d0309876de807cc434809b74c9cb7 Signed-off-by:
