In the old days (before linux-3.0), SNMP counters were duplicated, one for user context, and one for BH context. After commit 8f0ea0fe ("snmp: reduce percpu needs by 50%") we have a single copy, and what really matters is preemption being enabled or disabled, since we use this_cpu_inc() or __this_cpu_inc() respectively. We therefore kill SNMP_INC_STATS_USER(), SNMP_ADD_STATS_USER(), NET_INC_STATS_USER(), NET_ADD_STATS_USER(), SCTP_INC_STATS_USER(), SNMP_INC_STATS64_USER(), SNMP_ADD_STATS64_USER(), TCP_ADD_STATS_USER(), UDP_INC_STATS_USER(), UDP6_INC_STATS_USER(), and XFRM_INC_STATS_USER() Following patches will rename __BH helpers to make clear their usage is not tied to BH being disabled.

Jeff Kirsher says: ==================== 40GbE Intel Wired LAN Driver Updates 2016-04-27 This series contains updates to i40e and i40evf. Alex Duyck cleans up the feature flags since they are becoming pretty "massive", the primary change being that we now build our features list around hw_encap_features. Added support for IPIP and SIT offloads, which should improvement in throughput for IPIP and SIT tunnels with the offload enabled. Mitch adds support for configuring RSS on behalf of the VFs, which removes the burden of dealing with different hardware interfaces from the VF drivers and improves future compatibility. Fix to ensure that we do not panic by checking that the vsi_res pointer is valid before dereferencing it, after which we can drink beer and eat peanuts. Shannon does come housekeeping in i40e_add_fdir_ethtool() in preparation for more cloud filter work. Added flexibility to the nvmupdate facility by adding the ability to specify an AQ event opcode to wait on after Exec_AQ request. Michal adds device capability which defines if an update is available and if a security check is needed during the update process. Kamil just adds a device id to support X722 QSFP+ device. Greg fixes an issue where a mirror rule ID may be zero, so do not return invalid parameter when the user passes in a zero for a rule ID. Adds support to steer packets to VSIs by VLAN tag alone while being in promiscuous mode for multicast and unicast MAC addresses. Jesse fixes the driver from offloading the VLAN tag into the skb any time there was a VLAN tag and the hardware stripping was enabled, to making sure it is enabled before put_tag. v2: Dropped patch 8 ("i40e: Allow user to change input set mask for flow director") while Kiran reworks a more generalized solution based on feedback from David Miller. ==================== Signed-off-by: NDavid S.

This adds support for W5500 chip. W5500 has similar register and memory organization with W5100 and W5200. There are a few important differences listed below but it is still possible to share common code with W5100 and W5200. * W5500 register and memory are organized by multiple blocks. Each one is selected by 16bits offset address and 5bits block select bits. But the existing register access operations take u16 address. This change extends the addess by u32 address and put offset address to lower 16bits and block select bits to upper 16bits. This change also adds the offset addresses for socket register and TX/RX memory blocks to the driver private data structure in order to reduce conditional switches for each chip. * W5500 has the different register offset for socket interrupt mask register. Newly added internal functions w5100_enable_intr() and w5100_disable_intr() take care of the diffrence. * W5500 has the different register offset for retry time-value register. But this register is only used to verify that the reset value is correctly read at initialization. So move the verification to w5100_hw_reset() which already does different things for different chips.

This is more prep-work for the upcoming pty changes. Still just code cleanup with no actual semantic changes. This removes a bunch pointless complexity by just having the slave pty side remember the dentry associated with the devpts slave rather than the inode. That allows us to remove all the "look up the dentry" code for when we want to remove it again. Together with moving the tty pointer from "inode->i_private" to "dentry->d_fsdata" and getting rid of pointless inode locking, this removes about 30 lines of code. Not only is the end result smaller, it's simpler and easier to understand. The old code, for example, depended on the d_find_alias() to not just find the dentry, but also to check that it is still hashed, which in turn validated the tty pointer in the inode. That is a _very_ roundabout way to say "invalidate the cached tty pointer when the dentry is removed". The new code just does dentry->d_fsdata = NULL; in devpts_pty_kill() instead, invalidating the tty pointer rather more directly and obviously. Don't do something complex and subtle when the obvious straightforward approach will do. The rest of the patch (ie apart from code deletion and the above tty pointer clearing) is just switching the calling convention to pass the dentry or file pointer around instead of the inode.

When bpf(BPF_PROG_LOAD, ...) was invoked with a BPF program whose bytecode references a non-map file descriptor as a map file descriptor, the error handling code called fdput() twice instead of once (in __bpf_map_get() and in replace_map_fd_with_map_ptr()). If the file descriptor table of the current task is shared, this causes f_count to be decremented too much, allowing the struct file to be freed while it is still in use (use-after-free). This can be exploited to gain root privileges by an unprivileged user. This bug was introduced in commit 0246e64d ("bpf: handle pseudo BPF_LD_IMM64 insn"), but is only exploitable since commit 1be7f75d ("bpf: enable non-root eBPF programs") because previously, CAP_SYS_ADMIN was required to reach the vulnerable code.

We've done some code refactoring for ethtool statistics reporting, making it more scalable and robust, now each reported ethtool counter belongs to a group and has its own descriptor within that group, the descriptor holds the counter name and offset in memory in that group memory block. Added new counters: - Reporting more error and drop counter in ifconig/ip tool. - Per priority pause and traffic counter in ethtool. - link down events counter in ethtool. Set features handling was also refactored a little bit to be more resilient and generic, now setting more than one feature will not stop on the first failed one, but instead it will try to continue setting others. We made it generic to make it simpler for adding more features support, it is now done easily by only introducing a handler function of the new supported netdev feature, and let the generic handler do the job. New netdev features and ethtool support: - Netdev feature RXALL, set on/off FCS check offload. - Netdev feature HW_VLAN_CTAG_RX, set on/off rx-vlan stripping offload. - Ethtool interface identify. - Ethtool dump module EEPROM. ==================== Signed-off-by: NDavid S.

In current mlx5e ndo_set_features implementation, setting some features can success while others can fail. Today, we return one error code which doesn't reflect the current features status of the netdev at the end of the ndo callback. Set netdev->features with features which were successfully set in order to keep the current status in case of failure. For this purpose, define new Macro to set/unset specific feature in netdev->features. This patch introduces a mechanism that uses feature handlers for each feature. Set features will call a generic handler, which will then call a specific handler in his turn and update netdev->features according to it's return value. Each specific handler is responsible to perform driver specific actions, and updating params if needed.

VPort and software counters names are confusing and may be unclear, all VPort counters now have a prefix of rx/tx_vport_*. Signed-off-by: NGal Pressman <galp@mellanox.com> Signed-off-by: NSaeed Mahameed <saeedm@mellanox.com> Signed-off-by: NDavid S. Miller <davem@davemloft.net>

Redesign ethtool statistics handling and reporting in the driver: 1. Move counters to a separate file (en_stats.h). 2. Remove unnecessary dependencies between stats and strings. 3. Use counter descriptors which hold a name and offset for each counter, and will be used to decide which counters will be exposed. For example when adding a new software counter to ethtool, instead of: 1. Add to stats struct. 2. Add to strings struct in the same order. 3. Change macro defining number of software counters. The only thing needed is to link the new counter to a counter descriptor. VPort counters are a set of hardware traffic counters created automatically for each virtual port opened. PPort counters are a set of counters describing per physical port performance statistics. These counters are gathered from hardware register and divided to groups according to different protocols.

Florian Westphal says: ==================== net: core: remove TX_LOCKED support Not that many users left, lets kill it. TX_LOCKED was meant to be used by LLTX drivers when spin_trylock() failed. Stack then re-queued if collisions happened on different cpus or free'd the skb to prevent deadlocks. Most of the driver removal patches fall into one of three categories: 1. remove the driver-private tx lock (and LLTX flag), or... 2. convert spin_trylock to plain spin_lock, or... 3. convert TX_LOCKED to free+TX_OK Patches are grouped by these categories, last patch is the actual removal. All driver changes were compile tested only with exception of atl1e. ==================== Signed-off-by: NDavid S. Miller <davem@davemloft.net>
