The return value of kzalloc on failure of allocation of memory should be -ENOMEM and not -1. Found using Coccinelle. A simplified version of the semantic patch used is: //<smpl> @@ expression *e; position p,q; @@ e@q = kzalloc(...); if@p (e == NULL) { ... return - -1 + -ENOMEM ; } //</smpl> This function may also return -1 after calling mpp2_prs_tcam_port_map_get. So that the function consistently returns meaningful error values on failure, the -1 is changed to -EINVAL. Signed-off-by:

The current logic in bond_arp_rcv will accept an incoming ARP for validation if (a) the receiving slave is either "active" (which includes the currently active slave, or the current ARP slave) or, (b) there is a currently active slave, and it has received an ARP since it became active. For case (b), the receiving slave isn't the currently active slave, and is receiving the original broadcast ARP request, not an ARP reply from the target. This logic can fail if there is no currently active slave. In this situation, the ARP probe logic cycles through all slaves, assigning each in turn as the "current_arp_slave" for one arp_interval, then setting that one as "active," and sending an ARP probe from that slave. The current logic expects the ARP reply to arrive on the sending current_arp_slave, however, due to switch FDB updating delays, the reply may be directed to another slave. This can arise if the bonding slaves and switch are working, but the ARP target is not responding. When the ARP target recovers, a condition may result wherein the ARP target host replies faster than the switch can update its forwarding table, causing each ARP reply to be sent to the previous current_arp_slave. This will never pass the logic in bond_arp_rcv, as neither of the above conditions (a) or (b) are met. Some experimentation on a LAN shows ARP reply round trips in the 200 usec range, but my available switches never update their FDB in less than 4000 usec. This patch changes the logic in bond_arp_rcv to additionally accept an ARP reply for validation on any slave if there is a current ARP slave and it sent an ARP probe during the previous arp_interval.

When ctx access is used, the kernel often needs to expand/rewrite instructions, so after that patching, branch offsets have to be adjusted for both forward and backward jumps in the new eBPF program, but for backward jumps it fails to account the delta. Meaning, for example, if the expansion happens exactly on the insn that sits at the jump target, it doesn't fix up the back jump offset. Analysis on what the check in adjust_branches() is currently doing: /* adjust offset of jmps if necessary */ if (i < pos && i + insn->off + 1 > pos) insn->off += delta; else if (i > pos && i + insn->off + 1 < pos) insn->off -= delta; First condition (forward jumps): Before: After: insns[0] insns[0] insns[1] <--- i/insn insns[1] <--- i/insn insns[2] <--- pos insns[P] <--- pos insns[3] insns[P] `------| delta insns[4] <--- target_X insns[P] `-----| insns[5] insns[3] insns[4] <--- target_X insns[5] First case is if we cross pos-boundary and the jump instruction was before pos. This is handeled correctly. I.e. if i == pos, then this would mean our jump that we currently check was the patchlet itself that we just injected. Since such patchlets are self-contained and have no awareness of any insns before or after the patched one, the delta is correctly not adjusted. Also, for the second condition in case of i + insn->off + 1 == pos, means we jump to that newly patched instruction, so no offset adjustment are needed. That part is correct. Second condition (backward jumps): Before: After: insns[0] insns[0] insns[1] <--- target_X insns[1] <--- target_X insns[2] <--- pos <-- target_Y insns[P] <--- pos <-- target_Y insns[3] insns[P] `------| delta insns[4] <--- i/insn insns[P] `-----| insns[5] insns[3] insns[4] <--- i/insn insns[5] Second interesting case is where we cross pos-boundary and the jump instruction was after pos. Backward jump with i == pos would be impossible and pose a bug somewhere in the patchlet, so the first condition checking i > pos is okay only by itself. However, i + insn->off + 1 < pos does not always work as intended to trigger the adjustment. It works when jump targets would be far off where the delta wouldn't matter. But, for example, where the fixed insn->off before pointed to pos (target_Y), it now points to pos + delta, so that additional room needs to be taken into account for the check. This means that i) both tests here need to be adjusted into pos + delta, and ii) for the second condition, the test needs to be <= as pos itself can be a target in the backjump, too.

When looking up the pool_workqueue to use for an unbound workqueue, workqueue assumes that the target CPU is always bound to a valid NUMA node. However, currently, when a CPU goes offline, the mapping is destroyed and cpu_to_node() returns NUMA_NO_NODE. This has always been broken but hasn't triggered often enough before 874bbfe6 ("workqueue: make sure delayed work run in local cpu"). After the commit, workqueue forcifully assigns the local CPU for delayed work items without explicit target CPU to fix a different issue. This widens the window where CPU can go offline while a delayed work item is pending causing delayed work items dispatched with target CPU set to an already offlined CPU. The resulting NUMA_NO_NODE mapping makes workqueue try to queue the work item on a NULL pool_workqueue and thus crash. While 874bbfe6 has been reverted for a different reason making the bug less visible again, it can still happen. Fix it by mapping NUMA_NO_NODE to the default pool_workqueue from unbound_pwq_by_node(). This is a temporary workaround. The long term solution is keeping CPU -> NODE mapping stable across CPU off/online cycles which is being worked on. Signed-off-by:

David Wragg says: ==================== Set a large MTU on ovs-created tunnel devices Prior to 4.3, openvswitch tunnel vports (vxlan, gre and geneve) could transmit vxlan packets of any size, constrained only by the ability to send out the resulting packets. 4.3 introduced netdevs corresponding to tunnel vports. These netdevs have an MTU, which limits the size of a packet that can be successfully encapsulated. The default MTU values are low (1500 or less), which is awkwardly small in the context of physical networks supporting jumbo frames, and leads to a conspicuous change in behaviour for userspace. This patch series sets the MTU on openvswitch-created netdevs to be the relevant maximum (i.e. the maximum IP packet size minus any relevant overhead), effectively restoring the behaviour prior to 4.3. Where relevant, the limits on MTU values that can be directly set on the netdevs are also relaxed.

Allow the MTU of geneve devices to be set to large values, in order to exploit underlying networks with larger frame sizes. GENEVE does not have a fixed encapsulation overhead (an openvswitch rule can add variable length options), so there is no relevant maximum MTU to enforce. A maximum of IP_MAX_MTU is used instead. Encapsulated packets that are too big for the underlying network will get dropped on the floor. Signed-off-by:

Allow the MTU of vxlan devices without an underlying device to be set to larger values (up to a maximum based on IP packet limits and vxlan overhead). Previously, their MTUs could not be set to higher than the conventional ethernet value of 1500. This is a very arbitrary value in the context of vxlan, and prevented vxlan devices from being able to take advantage of jumbo frames etc. The default MTU remains 1500, for compatibility.

Workqueue used to guarantee local execution for work items queued without explicit target CPU. The guarantee is gone now which can break some usages in subtle ways. To flush out those cases, this patch implements a debug feature which forces round-robin CPU selection for all such work items. The debug feature defaults to off and can be enabled with a kernel parameter. The default can be flipped with a debug config option.

This reverts commit 874bbfe6. Workqueue used to implicity guarantee that work items queued without explicit CPU specified are put on the local CPU. Recent changes in timer broke the guarantee and led to vmstat breakage which was fixed by 176bed1d ("vmstat: explicitly schedule per-cpu work on the CPU we need it to run on"). vmstat is the most likely to expose the issue and it's quite possible that there are other similar problems which are a lot more difficult to trigger. As a preventive measure, 874bbfe6 ("workqueue: make sure delayed work run in local cpu") was applied to restore the local CPU guarnatee. Unfortunately, the change exposed a bug in timer code which got fixed by 22b886dd ("timers: Use proper base migration in add_timer_on()"). Due to code restructuring, the commit couldn't be backported beyond certain point and stable kernels which only had 874bbfe6 started crashing. The local CPU guarantee was accidental more than anything else and we want to get rid of it anyway. As, with the vmstat case fixed, 874bbfe6 is causing more problems than it's fixing, it has been decided to take the chance and officially break the guarantee by reverting the commit. A debug feature will be added to force foreign CPU assignment to expose cases relying on the guarantee and fixes for the individual cases will be backported to stable as necessary. Signed-off-by:

Long ago, Dave Jones complained about CONFIG_LOCALVERSION_AUTO: "I don't use the auto config, because I end up filling up /boot unless I go through and clean them out by hand every time I install a new one (which I do probably a dozen or so times a day). Is there some easy way to prune old builds I'm missing?" To which Bruce replied: "I run this by hand every now and then. I'm probably doing it all wrong" And if he is running it wrong, then so am I - because I've been using this script ever since. It is true that CONFIG_LOCALVERSION_AUTO easily ends up filling your /boot partition if you don't clean up old versions regularly, and this script helps make that easier. Checked with Bruce to see that it's fine to add this to the kernel scripts. Maybe people will come up with enhancements, but more importantly, this way I won't misplace this script whenever I install a new machine and start doing custom kernels for it. Signed-off-by:

We fix it by changing hmacids to host order when users get them with getsockopt. Fixes: Commit ed5a377d ("sctp: translate host order to network order when setting a hmacid") Signed-off-by:

Firmware posts the devcmd result in result ring. In case of timeout, driver does not increment the current result pointer and firmware could post the result after timeout has occurred. During next devcmd, driver would be reading the result of previous devcmd. Fix this by incrementing result even in case of timeout. Fixes: 373fb087 ("enic: add devcmd2") Signed-off-by:

tg3_tso_bug() can hit a condition where the entire tx ring is not big enough to segment the GSO packet. For example, if MSS is very small, gso_segs can exceed the tx ring size. When we hit the condition, it will cause tx timeout. tg3_tso_bug() is called to handle TSO and DMA hardware bugs. For TSO bugs, if tg3_tso_bug() cannot succeed, we have to drop the packet. For DMA bugs, we can still fall back to linearize the SKB and let the hardware transmit the TSO packet. This patch adds a function tg3_tso_bug_gso_check() to check if there are enough tx descriptors for GSO before calling tg3_tso_bug(). The caller will then handle the error appropriately - drop or lineraize the SKB. v2: Corrected patch description to avoid confusion. Signed-off-by:

Devices may have limits on the number of fragments in an skb they support. Current codebase uses a constant as maximum for number of fragments one skb can hold and use. When enabling scatter/gather and running traffic with many small messages the codebase uses the maximum number of fragments and may thereby violate the max for certain devices. The patch introduces a global variable as max number of fragments. Signed-off-by:

Petr Novopashenniy reported that ICMP redirects on SYN_RECV sockets were leading to RST. This is of course incorrect. A specific list of ICMP messages should be able to drop a SYN_RECV. For instance, a REDIRECT on SYN_RECV shall be ignored, as we do not hold a dst per SYN_RECV pseudo request. Bugzilla: https://bugzilla.kernel.org/show_bug.cgi?id=111751 Fixes: 079096f1 ("tcp/dccp: install syn_recv requests into ehash table") Reported-by:

Merge tag 'regmap-fix-v4.5-big-endian' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regmap Pull regmap fix from Mark Brown: "A single revert back to v4.4 endianness handling. Commit 29bb45f2 ("regmap-mmio: Use native endianness for read/write") attempted to fix some long standing bugs in the MMIO implementation for big endian systems caused by duplicate byte swapping in both regmap and readl()/writel(). Sadly the fix makes things worse rather than better, so revert it for now" * tag 'regmap-fix-v4.5-big-endian' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regmap: regmap: mmio: Revert to v4.4 endianness handling
