Quoting Andrey Vagin: When a conntrack is created by kernel, it is initialized (sets IPS_{DST,SRC}_NAT_DONE_BIT bits in nf_nat_setup_info) and only then it is added in hashes (__nf_conntrack_hash_insert), so one conntract can't be initialized from a few threads concurrently. ctnetlink can add an uninitialized conntrack (w/o IPS_{DST,SRC}_NAT_DONE_BIT) in hashes, then a few threads can look up this conntrack and start initialize it concurrently. It's dangerous, because BUG can be triggered from nf_nat_setup_info. Fix this race by always setting up nat, even if no CTA_NAT_ attribute was requested before inserting the ct into the hash table. In absence of CTA_NAT_ attribute, a null binding is created. This alters current behaviour: Before this patch, the first packet matching the newly injected conntrack would be run through the nat table since nf_nat_initialized() returns false. IOW, this forces ctnetlink users to specify the desired nat transformation on ct creation time. Thanks for Florian Westphal, this patch is based on his original patch to address this problem, including this patch description. Reported-By:Andrey Vagin <avagin@gmail.com> Signed-off-by:

Add a check if payload's length is a power of 2 when selecting ops. The fast ops were meant for well aligned loads, also this fixes a small bug when using a length of 3 with some offsets which causes only 1 byte to be loaded because the fast ops are chosen. Signed-off-by:

When using nftables with CONFIG_NETFILTER_XT_TARGET_TRACE=n, we get lots of "TRACE: filter:output:policy:1 IN=..." warnings as several places will leave skb->nf_trace uninitialised. Unlike iptables tracing functionality is not conditional in nftables, so always copy/zero nf_trace setting when nftables is enabled. Move this into __nf_copy() helper. Signed-off-by:

The 9p-virtio transport does zero copy on things larger than 1024 bytes in size. It accomplishes this by returning the physical addresses of pages to the virtio-pci device. At present, the translation is usually a bit shift. That approach produces an invalid page address when we read/write to vmalloc buffers, such as those used for Linux kernel modules. Any attempt to load a Linux kernel module from 9p-virtio produces the following stack. [<ffffffff814878ce>] p9_virtio_zc_request+0x45e/0x510 [<ffffffff814814ed>] p9_client_zc_rpc.constprop.16+0xfd/0x4f0 [<ffffffff814839dd>] p9_client_read+0x15d/0x240 [<ffffffff811c8440>] v9fs_fid_readn+0x50/0xa0 [<ffffffff811c84a0>] v9fs_file_readn+0x10/0x20 [<ffffffff811c84e7>] v9fs_file_read+0x37/0x70 [<ffffffff8114e3fb>] vfs_read+0x9b/0x160 [<ffffffff81153571>] kernel_read+0x41/0x60 [<ffffffff810c83ab>] copy_module_from_fd.isra.34+0xfb/0x180 Subsequently, QEMU will die printing: qemu-system-x86_64: virtio: trying to map MMIO memory This patch enables 9p-virtio to correctly handle this case. This not only enables us to load Linux kernel modules off virtfs, but also enables ZFS file-based vdevs on virtfs to be used without killing QEMU. Special thanks to both Avi Kivity and Alexander Graf for their interpretation of QEMU backtraces. Without their guidence, tracking down this bug would have taken much longer. Also, special thanks to Linus Torvalds for his insightful explanation of why this should use is_vmalloc_addr() instead of is_vmalloc_or_module_addr(): https://lkml.org/lkml/2014/2/8/272Signed-off-by:

Commit 46d3ceab ("tcp: TCP Small Queues") introduced a possible regression for applications using TCP_NODELAY. If TCP session is throttled because of tsq, we should consult tp->nonagle when TX completion is done and allow us to send additional segment, especially if this segment is not a full MSS. Otherwise this segment is sent after an RTO. [edumazet] : Cooked the changelog, added another fix about testing sk_wmem_alloc twice because TX completion can happen right before setting TSQ_THROTTLED bit. This problem is particularly visible with recent auto corking, but might also be triggered with low tcp_limit_output_bytes values or NIC drivers delaying TX completion by hundred of usec, and very low rtt. Thomas Glanzmann for example reported an iscsi regression, caused by tcp auto corking making this bug quite visible. Fixes: 46d3ceab ("tcp: TCP Small Queues") Signed-off-by:

Toshiaki Makita says: ==================== bridge: Fix corner case problems around local fdb entries There are so many corner cases that are not handled properly around local fdb entries. - We might fail to delete the old entry and might delete an arbitrary local entry when changing mac address of a bridge port. - We always fail to delete the old entry when changing mac address of the bridge device. - We might incorrectly delete a necessary entry when detaching a bridge port. - We might incorrectly delete a necessary entry when deleting a vlan. and so on. This is a patch series to fix these issues. v3: - Handle NTF_USE case in patch 1/9, commented by Vlad Yasevich. - Tested port detach/attach and didn't find any problem with patch 5/9, suggested by Stephen Hemminger. - Add comments about possible inconsistent state in current implementation into commit log of patch 5/9, found by the above test. - Reword unintensive changelog of patch 7/9, commented by Vlad Yasevich. v2: - Change the way to find the old entry in br_fdb_changeaddr() from memorizing previous port address to introducing a new flag indicating whether a fdb entry is added by user or not, commented by Stephen Hemminger. - Add a fix for the way to insert a new address in br_fdb_changeaddr(). - Prevent creating an entry such that its dst is NULL in br_add_if() to preserve old behavior, commented by Vlad Yasevich. - Add more comments about slight behavior change, where the bridge device come to be able to receive traffic to an address it has during short window, to changelogs, commented by Vlad Yasevich. - Add a fix for possible race in br_fdb_change_mac_address(). ==================== Signed-off-by: -

Vlan codes unconditionally delete local fdb entries. We should consider the possibility that other ports have the same address and vlan. Example of problematic case: ip link set eth0 address 12:34:56:78:90:ab ip link set eth1 address aa:bb:cc:dd:ee:ff brctl addif br0 eth0 brctl addif br0 eth1 # br0 will have mac address 12:34:56:78:90:ab bridge vlan add dev eth0 vid 10 bridge vlan add dev eth1 vid 10 bridge vlan add dev br0 vid 10 self We will have fdb entry such that f->dst == eth0, f->vlan_id == 10 and f->addr == 12:34:56:78:90:ab at this time. Next, delete eth0 vlan 10. bridge vlan del dev eth0 vid 10 In this case, we still need the entry for br0, but it will be deleted. Note that br0 needs the entry even though its mac address is not set manually. To delete the entry with proper condition checking, fdb_delete_local() is suitable to use. Signed-off-by:

br_fdb_delete_by_port() doesn't care about vlan and mac address of the bridge device. As the check is almost the same as mac address changing, slightly modify fdb_delete_local() and use it. Note that we can always set added_by_user to 0 in fdb_delete_local() because - br_fdb_delete_by_port() calls fdb_delete_local() for local entries regardless of its added_by_user. In this case, we have to check if another port has the same address and vlan, and if found, we have to create the entry (by changing dst). This is kernel-added entry, not user-added. - br_fdb_changeaddr() doesn't call fdb_delete_local() for user-added entry. Signed-off-by:

br_fdb_change_mac_address() doesn't check if the local entry has the same address as any of bridge ports. Although I'm not sure when it is beneficial, current implementation allow the bridge device to receive any mac address of its ports. To preserve this behavior, we have to check if the mac address of the entry being deleted is identical to that of any port. As this check is almost the same as that in br_fdb_changeaddr(), create a common function fdb_delete_local() and call it from br_fdb_changeadddr() and br_fdb_change_mac_address(). Signed-off-by:

We should take into account the followings when deleting a local fdb entry. - nbp_vlan_find() can be used only when vid != 0 to check if an entry is deletable, because a fdb entry with vid 0 can exist at any time while nbp_vlan_find() always return false with vid 0. Example of problematic case: ip link set eth0 address 12:34:56:78:90:ab ip link set eth1 address 12:34:56:78:90:ab brctl addif br0 eth0 brctl addif br0 eth1 ip link set eth0 address aa:bb:cc:dd:ee:ff Then, the fdb entry 12:34:56:78:90:ab will be deleted even though the bridge port eth1 still has that address. - The port to which the bridge device is attached might needs a local entry if its mac address is set manually. Example of problematic case: ip link set eth0 address 12:34:56:78:90:ab brctl addif br0 eth0 ip link set br0 address 12:34:56:78:90:ab ip link set eth0 address aa:bb:cc:dd:ee:ff Then, the fdb still must have the entry 12:34:56:78:90:ab, but it will be deleted. We can use br->dev->addr_assign_type to check if the address is manually set or not, but I propose another approach. Since we delete and insert local entries whenever changing mac address of the bridge device, we can change dst of the entry to NULL regardless of addr_assign_type when deleting an entry associated with a certain port, and if it is found to be unnecessary later, then delete it. That is, if changing mac address of a port, the entry might be changed to its dst being NULL first, but is eventually deleted when recalculating and changing bridge id. This approach is especially useful when we want to share the code with deleting vlan in which the bridge device might want such an entry regardless of addr_assign_type, and makes things easy because we don't have to consider if mac address of the bridge device will be changed or not at the time we delete a local entry of a port, which means fdb code will not be bothered even if the bridge id calculating logic is changed in the future. Also, this change reduces inconsistent state, where frames whose dst is the mac address of the bridge, can't reach the bridge because of premature fdb entry deletion. This change reduces the possibility that the bridge device replies unreachable mac address to arp requests, which could occur during the short window between calling del_nbp() and br_stp_recalculate_bridge_id() in br_del_if(). This will effective after br_fdb_delete_by_port() starts to use the same code by following patch. Signed-off-by: -

Vlan code may need fdb change when changing mac address of bridge device even if it is caused by the mac address changing of a bridge port. Example configuration: ip link set eth0 address 12:34:56:78:90:ab ip link set eth1 address aa:bb:cc:dd:ee:ff brctl addif br0 eth0 brctl addif br0 eth1 # br0 will have mac address 12:34:56:78:90:ab bridge vlan add dev br0 vid 10 self bridge vlan add dev eth0 vid 10 We will have fdb entry such that f->dst == NULL, f->vlan_id == 10 and f->addr == 12:34:56:78:90:ab at this time. Next, change the mac address of eth0 to greater value. ip link set eth0 address ee:ff:12:34:56:78 Then, mac address of br0 will be recalculated and set to aa:bb:cc:dd:ee:ff. However, an entry aa:bb:cc:dd:ee:ff will not be created and we will be not able to communicate using br0 on vlan 10. Address this issue by deleting and adding local entries whenever changing the mac address of the bridge device. If there already exists an entry that has the same address, for example, in case that br_fdb_changeaddr() has already inserted it, br_fdb_change_mac_address() will simply fail to insert it and no duplicated entry will be made, as it was. This approach also needs br_add_if() to call br_fdb_insert() before br_stp_recalculate_bridge_id() so that we don't create an entry whose dst == NULL in this function to preserve previous behavior. Note that this is a slight change in behavior where the bridge device can receive the traffic to the new address before calling br_stp_recalculate_bridge_id() in br_add_if(). However, it is not a problem because we have already the address on the new port and such a way to insert new one before recalculating bridge id is taken in br_device_event() as well. Signed-off-by:

We have been always failed to delete the old entry at br_fdb_change_mac_address() because br_set_mac_address() updates dev->dev_addr before calling br_fdb_change_mac_address() and br_fdb_change_mac_address() uses dev->dev_addr to find the old entry. That update of dev_addr is completely unnecessary because the same work is done in br_stp_change_bridge_id() which is called right away after calling br_fdb_change_mac_address(). Signed-off-by:

Since commit bc9a25d2 ("bridge: Add vlan support for local fdb entries"), br_fdb_changeaddr() has inserted a new local fdb entry only if it can find old one. But if we have two ports where they have the same address or user has deleted a local entry, there will be no entry for one of the ports. Example of problematic case: ip link set eth0 address aa:bb:cc:dd:ee:ff ip link set eth1 address aa:bb:cc:dd:ee:ff brctl addif br0 eth0 brctl addif br0 eth1 # eth1 will not have a local entry due to dup. ip link set eth1 address 12:34:56:78:90:ab Then, the new entry for the address 12:34:56:78:90:ab will not be created, and the bridge device will not be able to communicate. Insert new entries regardless of whether we can find old entries or not. Signed-off-by:

br_fdb_changeaddr() assumes that there is at most one local entry per port per vlan. It used to be true, but since commit 36fd2b63 ("bridge: allow creating/deleting fdb entries via netlink"), it has not been so. Therefore, the function might fail to search a correct previous address to be deleted and delete an arbitrary local entry if user has added local entries manually. Example of problematic case: ip link set eth0 address ee:ff:12:34:56:78 brctl addif br0 eth0 bridge fdb add 12:34:56:78:90:ab dev eth0 master ip link set eth0 address aa:bb:cc:dd:ee:ff Then, the address 12:34:56:78:90:ab might be deleted instead of ee:ff:12:34:56:78, the original mac address of eth0. Address this issue by introducing a new flag, added_by_user, to struct net_bridge_fdb_entry. Note that br_fdb_delete_by_port() has to set added_by_user to 0 in cases like: ip link set eth0 address 12:34:56:78:90:ab ip link set eth1 address aa:bb:cc:dd:ee:ff brctl addif br0 eth0 bridge fdb add aa:bb:cc:dd:ee:ff dev eth0 master brctl addif br0 eth1 brctl delif br0 eth0 In this case, kernel should delete the user-added entry aa:bb:cc:dd:ee:ff, but it also should have been added by "brctl addif br0 eth1" originally, so we don't delete it and treat it a new kernel-created entry.

This eliminates the following warning in caif/cfsrvl.c: net/caif/cfsrvl.c:198:6: warning: no previous prototype for ‘caif_free_client’ [-Wmissing-prototypes] net/caif/cfsrvl.c:208:6: warning: no previous prototype for ‘caif_client_register_refcnt’ [-Wmissing-prototypes] Signed-off-by:
