commit 416186fb ("net: Split core bits of netdev_pick_tx into __netdev_pick_tx") added a bug that disables caching of queue index in the socket. This is the source of packet reorders for TCP flows, and again this is happening more often when using FQ pacing. Old code was doing if (queue_index != old_index) sk_tx_queue_set(sk, queue_index); Alexander renamed the variables but forgot to change sk_tx_queue_set() 2nd parameter. if (queue_index != new_index) sk_tx_queue_set(sk, queue_index); This means we store -1 over and over in sk->sk_tx_queue_mapping Signed-off-by: NEric Dumazet <edumazet@google.com> Cc: Alexander Duyck <alexander.h.duyck@intel.com> Acked-by: NAlexander Duyck <alexander.h.duyck@intel.com> Signed-off-by: NDavid S.

This was originally reported in [1] and posted by Neil Horman [2], he said: Fix up a missed null pointer check in the asconf code. If we don't find a local address, but we pass in an address length of more than 1, we may dereference a NULL laddr pointer. Currently this can't happen, as the only users of the function pass in the value 1 as the addrcnt parameter, but its not hot path, and it doesn't hurt to check for NULL should that ever be the case. The callpath from sctp_asconf_mgmt() looks okay. But this could be triggered from sctp_setsockopt_bindx() call with SCTP_BINDX_REM_ADDR and addrcnt > 1 while passing all possible addresses from the bind list to SCTP_BINDX_REM_ADDR so that we do *not* find a single address in the association's bind address list that is not in the packed array of addresses. If this happens when we have an established association with ASCONF-capable peers, then we could get a NULL pointer dereference as we only check for laddr == NULL && addrcnt == 1 and call later sctp_make_asconf_update_ip() with NULL laddr. BUT: this actually won't happen as sctp_bindx_rem() will catch such a case and return with an error earlier. As this is incredably unintuitive and error prone, add a check to catch at least future bugs here. As Neil says, its not hot path. Introduced by 8a07eb0a ("sctp: Add ASCONF operation on the single-homed host").

If we do not add braces around ... mask |= POLLERR | sock_flag(sk, SOCK_SELECT_ERR_QUEUE) ? POLLPRI : 0; ... then this condition always evaluates to true as POLLERR is defined as 8 and binary or'd with whatever result comes out of sock_flag(). Hence instead of (X | Y) ?

When the kernel is compiled with CONFIG_IPV6_SUBTREES, and we return with an error in fn = fib6_add_1(), then error codes are encoded into the return pointer e.g. ERR_PTR(-ENOENT). In such an error case, we write the error code into err and jump to out, hence enter the if(err) condition. Now, if CONFIG_IPV6_SUBTREES is enabled, we check for: if (pn != fn && pn->leaf == rt) ... if (pn != fn && !pn->leaf && !(pn->fn_flags & RTN_RTINFO)) ... Since pn is NULL and fn is f.e. ERR_PTR(-ENOENT), then pn != fn evaluates to true and causes a NULL-pointer dereference on further checks on pn. Fix it, by setting both NULL in error case, so that pn != fn already evaluates to false and no further dereference takes place. This was first correctly implemented in 4a287eba ("IPv6 routing, NLM_F_* flag support: REPLACE and EXCL flags support, warn about missing CREATE flag"), but the bug got later on introduced by 188c517a ("ipv6: return errno pointers consistently for fib6_add_1()").

In function __parse_flow_nlattrs(), we check for condition (type > OVS_KEY_ATTR_MAX) and if true, print an error, but we do not return from this function as in other checks. It seems this has been forgotten, as otherwise, we could access beyond the memory of ovs_key_lens, which is of ovs_key_lens[OVS_KEY_ATTR_MAX + 1]. Hence, a maliciously prepared nla_type from user space could access beyond this upper limit. Introduced by 03f0d916 ("openvswitch: Mega flow implementation").

Currently macvlan calls skb_clone in macvlan_broadcast but checks for a NULL return in macvlan_broadcast_one instead. This is needlessly confusing and may lead to bugs introduced later. This patch moves the error check to where the skb_clone call is. The only other caller of macvlan_broadcast_one never passes in a NULL value so it doesn't need the check either.

We make bond_arp_rcv global so it can be used in bond_sysfs if the bond interface is up and arp_interval is being changed to a positive value and cleared otherwise as per Jay's suggestion. This also fixes a problem where bond_arp_rcv was set even though arp_validate was disabled while the bond was up by unsetting recv_probe in bond_store_arp_validate and respectively setting it if enabled.

During initialization bnx2x allocates significant amounts of memory (for rx data, rx SGEs, TPA pool) using atomic allocations. I received a report where bnx2x failed to allocate SGEs and it had to fall back to TPA-less operation. Let's use GFP_KERNEL allocations during initialization, which runs in process context. Add gfp_t parameters to functions that are used both in initialization and in the receive path. Use an unlikely branch in bnx2x_frag_alloc() to avoid atomic allocation by netdev_alloc_frag(). The branch is taken several thousands of times during initialization, but then never more. Note that fp->rx_frag_size is never greater than PAGE_SIZE, so __get_free_page() can be used here.

This is the fix that the last two commits indirectly led up to - making sure that we don't call dput() in a bad context on the dentries we've looked up in RCU mode after the sequence count validation fails. This basically expands d_rcu_to_refcount() into the callers, and then fixes the callers to delay the dput() in the failure case until _after_ we've dropped all locks and are no longer in an RCU-locked region. The case of 'complete_walk()' was trivial, since its failure case did the unlock_rcu_walk() directly after the call to d_rcu_to_refcount(), and as such that is just a pure expansion of the function with a trivial movement of the resulting dput() to after 'unlock_rcu_walk()'. In contrast, the unlazy_walk() case was much more complicated, because not only does convert two different dentries from RCU to be reference counted, but it used to not call unlock_rcu_walk() at all, and instead just returned an error and let the caller clean everything up in "terminate_walk()". Happily, one of the dentries in question (called "parent" inside unlazy_walk()) is the dentry of "nd->path", which terminate_walk() wants a refcount to anyway for the non-RCU case. So what the new and improved unlazy_walk() does is to first turn that dentry into a refcounted one, and once that is set up, the error cases can continue to use the terminate_walk() helper for cleanup, but for the non-RCU case. Which makes it possible to drop out of RCU mode if we actually hit the sequence number failure case.

The virtio_pci_freeze/restore are defined under CONFIG_PM but is used by SET_SYSTEM_SLEEP_PM_OPS macro, which is defined under CONFIG_PM_SLEEP. So if CONFIG_PM_SLEEP is not cofigured but CONFIG_PM_RUNTIME is, the following warning message appeared: drivers/virtio/virtio_pci.c:770:12: warning: ‘virtio_pci_freeze’ defined but not used [-Wunused-function] static int virtio_pci_freeze(struct device *dev) ^ drivers/virtio/virtio_pci.c:790:12: warning: ‘virtio_pci_restore’ defined but not used [-Wunused-function] static int virtio_pci_restore(struct device *dev) ^ Fix it by changing CONFIG_PM to CONFIG_PM_SLEEP.

This simplifies the RCU to refcounting code in particular. I was originally intending to leave this for later, but walking through all the dput() logic (see previous commit), I realized that the dput() "might_sleep()" check was misleadingly weak. And I removed it as misleading, both for performance profiling and for debugging. However, the might_sleep() debugging case is actually true: the final dput() can indeed sleep, if the inode of the dentry that you are releasing ends up sleeping at iput time (see dentry_iput()). So the problem with the might_sleep() in dput() wasn't that it wasn't true, it was that it wasn't actually testing and triggering on the interesting case. In particular, just about *any* dput() can indeed sleep, if you happen to race with another thread deleting the file in question, and you then lose the race to the be the last dput() for that file. But because it's a very rare race, the debugging code would never trigger it in practice. Why is this problematic? The new d_rcu_to_refcount() (see commit 15570086: "vfs: reimplement d_rcu_to_refcount() using lockref_get_or_lock()") does a dput() for the failure case, and it does it under the RCU lock. So potentially sleeping really is a bug. But there's no way I'm going to fix this with the previous complicated "lockref_get_or_lock()" interface. And rather than revert to the old and crufty nested dentry locking code (which did get this right by delaying the reference count updates until they were verified to be safe), let's make forward progress.

This is me being a bit OCD after all the dentry optimization work this merge window: profiles end up showing 'dput()' as a rather expensive operation, and there were two unrelated bad reasons for that. The first reason was reading d_lockref.count for debugging purposes, which touches the lockref cacheline (for reads) before really need to. More importantly, the debugging test in question is _wrong_, and has hidden bugs. It's true that we can only sleep when the count goes down to zero, but the test as-is hides the much more subtle bug that happens if we race with somebody else deleting the file. Anyway we _will_ touch that cacheline, but let's do it for a write and in the right routine (ie in "lockref_put_or_lock()") which annotates the costs better. So remove the misleading debug code. The other was an unnecessary access to the cacheline that contains the d_lru list, just to check whether we already were on the LRU list or not. This is exactly what we have d_flags for, so that we can avoid touching extra cache lines for the common case. So just add another bit for "is this dentry on the LRU". Finally, mark the tests properly likely/unlikely, so that the common fast-paths are dense in the instruction stream. This makes the profiles look much saner.
