2018-11-28netfilter: nf_tables: deactivate expressions in rule replecement routineTaehee Yoo1-11/+4
There is no expression deactivation call from the rule replacement path, hence, chain counter is not decremented. A few steps to reproduce the problem: %nft add table ip filter %nft add chain ip filter c1 %nft add chain ip filter c1 %nft add rule ip filter c1 jump c2 %nft replace rule ip filter c1 handle 3 accept %nft flush ruleset <jump c2> expression means immediate NFT_JUMP to chain c2. Reference count of chain c2 is increased when the rule is added. When rule is deleted or replaced, the reference counter of c2 should be decreased via nft_rule_expr_deactivate() which calls nft_immediate_deactivate().

To do this, it grabs the lock 'node_list_lock', which may at the same time be held by the generic node cleanup function, tipc_node_stop(), during module removal. Since the latter is calling del_timer_sync() inside the same lock, we have a potential deadlock. We fix this letting the timer cleanup function use spin_trylock() instead of just spin_lock(), and when it fails to grab the lock it just returns so that the timer handler can terminate its execution. This is safe to do, since tipc_node_stop() anyway is about to delete both the timer and the node instance.

In the case of internal reload (e.g., mtu change), there could be a race between link-up notification from mfw and the driver unload processing. In such case kernel assumes the link is up and starts using the queues which leads to the server crash. Send link notification to the kernel only when driver has already requested MFW for the link.

2018-11-27qede: Simplify the usage of qede-flags.Sudarsana Reddy Kalluru3-8/+11
The values represented by qede->flags is being used in mixed ways: 1. As 'value' at some places e.g., QEDE_FLAGS_IS_VF usage 2. As bit-mask(value) at some places e.g., QEDE_FLAGS_PTP_TX_IN_PRORGESS usage. This implementation pose problems in future when we want to add more flag values e.g., overlap of the values, overflow of 64-bit storage. Updated the implementation to go with approach (2) for qede->flags.

MFW sends UFP notifications mostly during the device init phase and PFs might not be assigned with a name by this time. Hence capturing port-id in the debug messages would help in finding which PF the ufp notification was sent to. Also, fixed a minor scemantic issue in a debug print.

Igor Russkikh says: ==================== Add support for Aquantia AQtion USB to 5/2.5GbE devices This patchset introduces support for new multigig ethernet to USB dongle, developed jointly by Aquantia (Phy) and ASIX (USB MAC). The driver has similar structure with other ASIX MAC drivers (AX88179), but with a number of important differences: - Driver supports both direct Phy and custom firmware interface for Phy programming. This is due to different firmware modules available with this product. - Driver handles new 2.5G/5G link speed configuration and reporting. - Device support all speeds from 100M up to 5G. - Device supports MTU up to 16K. Device supports various standard networking features, like checksum offloads, vlan tagging/filtering, TSO. The code of this driver is based on original ASIX sources and was extended by Aquantia for 5G multigig support. Patchset v2 includes following changes: - Function variables declarions fixed to reverse xmass tree - Improve patch layout structure - Remove unnecessary curly braces in switch/case statements - Use 'packed' attribute for HW structures only - Use eth_mac_addr function in set_mac_addr callback - Remove unnecessary 'memset' calls. - Read MAC address from EEPROM function has now better name - Use driver_priv field to store context. It avoids ugly cast. - Set max_mtu field. Remove check for MTU size - Rewrite read/write functions. Add helpers for read/write 16/32 bit values - Use mask and shifts instead of bitfields to support BE platforms. - Use stack allocated buffer for configuring mcast filters - Use AUTONEG_ENABLE when go to suspend state - Pad out wol_cfg field from context structure. Use stack allocated instead - Remove driver version - Check field 'duplex' in set_link_ksetting callback as well - Use already created defines in usb matching macro - Rename phy_ops struct to phy_cfg - Use ether_addr_copy for copying mac address - Add fall-through comment in switch/case for avoid checkpatch warning - Remove match for CDC ether device - Add ASIX's HW id-s to match this driver - Add all HW id-s with which driver can work to blacklist of cdc_ether driver Patchset v3 includes following changes: - Use linkmode_copy instead of bitmap_copy - Remove Direct PHY access code since production HW will not have this mode anymore - Fix line over 80 symbols and alignments in cdc_ether patch - Add match for ECM configuration On start our HW reports both ECM and vendor configs. Linux prefers to use ECM driver and chooses active configuration which is for ecm driver (not for vendor specific). We need to match this configuration and forcibly switch configuration to vendor specific. Patchset v4 includes following changes: - Set gso_max_size. - Optimize accessing to descriptors - Use SKB_TRUESIZE macro. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
