This patch attempts to untangle the TX and RX code in qeth from af_iucv's respective HiperTransport path: On the TX side, pointing skb_network_header() at the IUCV header means that qeth_l3_fill_af_iucv_hdr() no longer needs a magical offset to access the header. On the RX side, qeth pulls the (fake) L2 header off the skb like any normal ethernet driver would. This makes working with the IUCV header in af_iucv easier, since we no longer have to assume a fixed skb layout. While at it, replace the open-coded length checks in af_iucv's RX path with pskb_may_pull(). Signed-off-by: Julian Wiedmann <jwi@linux.ibm.com> Signed-off-by: David S. Miller <davem@davemloft.net>

qeth_core_probe_device() sets the gdev's drvdata, but doesn't reset it on a subsequent error. Move the (re-)setting around a bit, so that it happens symmetrically on allocating/freeing the qeth_card struct. This is no actual problem, as the ccwgroup core will discard the gdev on a probe error. But from qeth's perspective the gdev is an external resource, so it's best to manage it cleanly.

Device initialization code usually first loads a subdriver (via qeth_core_load_discipline()), and then runs its setup() callback. If this fails, it rolls back the load via qeth_core_free_discipline(). qeth_core_free_discipline() expects the options.layer attribute to be initialized, but on error in setup() that's currently not the case. Resulting in misbalanced symbol_put() calls. Fix this by setting options.layer when loading the subdriver. Signed-off-by: Julian Wiedmann <jwi@linux.ibm.com> Signed-off-by: David S.

Daniel Borkmann says: ==================== pull-request: bpf-next 2018-09-25 The following pull-request contains BPF updates for your *net-next* tree. The main changes are: 1) Allow for RX stack hardening by implementing the kernel's flow dissector in BPF. Idea was originally presented at netconf 2017 [0]. Quote from merge commit: [...] Because of the rigorous checks of the BPF verifier, this provides significant security guarantees. In particular, the BPF flow dissector cannot get inside of an infinite loop, as with CVE-2013-4348, because BPF programs are guaranteed to terminate. It cannot read outside of packet bounds, because all memory accesses are checked. Also, with BPF the administrator can decide which protocols to support, reducing potential attack surface. Rarely encountered protocols can be excluded from dissection and the program can be updated without kernel recompile or reboot if a bug is discovered. [...] Also, a sample flow dissector has been implemented in BPF as part of this work, from Petar and Willem. [0] http://vger.kernel.org/netconf2017_files/rx_hardening_and_udp_gso.pdf 2) Add support for bpftool to list currently active attachment points of BPF networking programs providing a quick overview similar to bpftool's perf subcommand, from Yonghong. 3) Fix a verifier pruning instability bug where a union member from the register state was not cleared properly leading to branches not being pruned despite them being valid candidates, from Alexei. 4) Various smaller fast-path optimizations in XDP's map redirect code, from Jesper. 5) Enable to recognize BPF_MAP_TYPE_REUSEPORT_SOCKARRAY maps in bpftool, from Roman. 6) Remove a duplicate check in libbpf that probes for function storage, from Taeung. 7) Fix an issue in test_progs by avoid checking for errno since on success its value should not be checked, from Mauricio. 8) Fix unused variable warning in bpf_getsockopt() helper when CONFIG_INET is not configured, from Anders. 9) Fix a compilation failure in the BPF sample code's use of bpf_flow_keys, from Prashant. 10) Minor cleanups in BPF code, from Yue and Zhong. ==================== Signed-off-by: David S.

The BMCR.RESET bit on the Marvell PHYs has a special meaning in that it commits the register writes into the HW for it to latch and be configured appropriately. Doing software resets causes link drops, and this is unnecessary disruption if nothing changed. Determine from marvell_set_polarity()'s return code whether the register value was changed and if it was, propagate that to the logic that hits the software reset bit. This avoids doing unnecessary soft reset if the PHY is configured in the same state it was previously, this also eliminates the need for a m88e1111_config_aneg() function since it now is the same as marvell_config_aneg().

While consolidating the PHY reset in phy_init_hw() an unconditionaly BMCR soft-reset I became quite trigger happy with those. This was later on deactivated for the Generic PHY driver on the premise that a prior software entity (e.g: bootloader) might have applied workarounds in commit 0878fff1 ("net: phy: Do not perform software reset for Generic PHY"). Since we have a hook to wire-up a soft_reset callback, just use that and get rid of the call to genphy_soft_reset() entirely. This speeds up initialization and link establishment for most PHYs out there that do not require a reset.

Jeff Kirsher says: ==================== 40GbE Intel Wired LAN Driver Updates 2018-09-25 This series contains updates to i40e and xsk. Mariusz fixes an issue where the VF link state was not being updated properly when the PF is down or up. Also cleaned up the promiscuous configuration during a VF reset. Patryk simplifies the code a bit to use the variables for PF and HW that are declared, rather than using the VSI pointers. Cleaned up the message length parameter to several virtchnl functions, since it was not being used (or needed). Harshitha fixes two potential race conditions when trying to change VF settings by creating a helper function to validate that the VF is enabled and that the VSI is set up. Sergey corrects a double "link down" message by putting in a check for whether or not the link is up or going down. Björn addresses an AF_XDP zero-copy issue that buffers passed from userspace to the kernel was leaked when the hardware descriptor ring was torn down. A zero-copy capable driver picks buffers off the fill ring and places them on the hardware receive ring to be completed at a later point when DMA is complete. Similar on the transmit side; The driver picks buffers off the transmit ring and places them on the transmit hardware ring. In the typical flow, the receive buffer will be placed onto an receive ring (completed to the user), and the transmit buffer will be placed on the completion ring to notify the user that the transfer is done. However, if the driver needs to tear down the hardware rings for some reason (interface goes down, reconfiguration and such), the userspace buffers cannot be leaked. They have to be reused or completed back to userspace. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

Vlad Buslov says: ==================== Refactor classifier API to work with Qdisc/blocks without rtnl lock Currently, all netlink protocol handlers for updating rules, actions and qdiscs are protected with single global rtnl lock which removes any possibility for parallelism. This patch set is a third step to remove rtnl lock dependency from TC rules update path. Recently, new rtnl registration flag RTNL_FLAG_DOIT_UNLOCKED was added. Handlers registered with this flag are called without RTNL taken. End goal is to have rule update handlers(RTM_NEWTFILTER, RTM_DELTFILTER, etc.) to be registered with UNLOCKED flag to allow parallel execution. However, there is no intention to completely remove or split rtnl lock itself. This patch set addresses specific problems in implementation of classifiers API that prevent its control path from being executed concurrently. Additional changes are required to refactor classifiers API and individual classifiers for parallel execution. This patch set lays groundwork to eventually register rule update handlers as rtnl-unlocked by modifying code in cls API that works with Qdiscs and blocks. Following patch set does the same for chains and classifiers. The goal of this change is to refactor tcf_block_find() and its dependencies to allow concurrent execution: - Extend Qdisc API with rcu to lookup and take reference to Qdisc without relying on rtnl lock. - Extend tcf_block with atomic reference counting and rcu. - Always take reference to tcf_block while working with it. - Implement tcf_block_release() to release resources obtained by tcf_block_find() - Create infrastructure to allow registering Qdiscs with class ops that do not require the caller to hold rtnl lock. All three netlink rule update handlers use tcf_block_find() to lookup Qdisc and block, and this patch set introduces additional means of synchronization to substitute rtnl lock in cls API. Some functions in cls and sch APIs have historic names that no longer clearly describe their intent. In order not make this code even more confusing when introducing their concurrency-friendly versions, rename these functions to describe actual implementation. Changes from V2 to V3: - Patch 1: - Explicitly include refcount.h in rtnetlink.h. - Patch 3: - Move rcu_head field to the end of struct Qdisc. - Rearrange local variable declarations in qdisc_lookup_rcu(). - Patch 5: - Remove tcf_qdisc_put() and inline its content to callers. Changes from V1 to V2: - Rebase on latest net-next. - Patch 8 - remove. - Patch 9 - fold into patch 11. - Patch 11: - Rename tcf_block_{get|put}() to tcf_block_refcnt_{get|put}(). - Patch 13 - remove. ==================== Acked-by: Cong Wang <xiyou.wangcong@gmail.com> Signed-off-by: David S.

Implement get/put function for blocks that only take/release the reference and perform deallocation. These functions are intended to be used by unlocked rules update path to always hold reference to block while working with it. They use on new fine-grained locking mechanisms introduced in previous patches in this set, instead of relying on global protection provided by rtnl lock. Extract code that is common with tcf_block_detach_ext() into common function __tcf_block_put(). Extend tcf_block with rcu to allow safe deallocation when it is accessed concurrently.

As a preparation for removing rtnl lock dependency from rules update path, change tcf block reference counter type to refcount_t to allow modification by concurrent users. In block put function perform decrement and check reference counter once to accommodate concurrent modification by unlocked users. After this change tcf_chain_put at the end of block put function is called with block->refcnt==0 and will deallocate block after the last chain is released, so there is no need to manually deallocate block in this case. However, if block reference counter reached 0 and there are no chains to release, block must still be deallocated manually.

Outstanding Rx descriptors are temporarily stored on a stash/reuse queue. When/if the HW rings comes up again, entries from the stash are used to re-populate the ring. The latter required some restructuring of the allocation scheme for the AF_XDP zero-copy implementation. There is now a fast, and a slow allocation. The "fast allocation" is used from the fast-path and obtains free buffers from the fill ring and the internal recycle mechanism. The "slow allocation" is only used in ring setup, and obtains buffers from the fill ring and the stash (if any).

When we are trying to change VF settings, it is possible for 2 race conditions to happen. One, when the VF is created but not yet enabled. Second, the VF is enabled but the VSI is still not created or not yet re-created in the VF reset flow. This patch introduces a helper function to validate that the VF is enabled and that the VSI is set up. This patch also calls this function from other functions which could get into these race conditions. While we are poking around here, remove unnecessary parenthesis that checkpatch was complaining about.

Vakul Garg authored
Current async encryption implementation sometimes showed up socket memory accounting error during socket close. This results in kernel warning calltrace. The root cause of the problem is that socket var sk_forward_alloc gets corrupted due to access in sk_mem_charge() and sk_mem_uncharge() being invoked from multiple concurrent contexts in multicore processor. The apis sk_mem_charge() and sk_mem_uncharge() are called from functions alloc_plaintext_sg(), free_sg() etc. It is required that memory accounting apis are called under a socket lock. The plaintext sg data sent for encryption is freed using free_sg() in tls_encryption_done(). It is wrong to call free_sg() from this function. This is because this function may run in irq context. We cannot acquire socket lock in this function. We remove calling of function free_sg() for plaintext data from tls_encryption_done() and defer freeing up of plaintext data to the time when the record is picked up from tx_list and transmitted/freed. When tls_tx_records() gets called, socket is already locked and thus there is no concurrent access problem.
