2022-09-21net/af_packet: registration process optimization in packet_init()Ziyang Xuan
Now, register_pernet_subsys() and register_netdevice_notifier() are both after sock_register(). It can create PF_PACKET socket and process socket once sock_register() successfully. It is possible PF_PACKET socket is creating but register_pernet_subsys() and register_netdevice_notifier() are not registered yet. Thus net->packet.sklist_lock and net->packet.sklist will be accessed without initialization that is done in packet_net_init(). Although this is a low probability scenario. Move register_pernet_subsys() and register_netdevice_notifier() to the front in packet_init(). Correspondingly, adjust the unregister process in packet_exit().

If aq_nic_stop() fails, aq_ndev_close() returns err without calling aq_nic_deinit() to release the relevant memory and resource, which will lead to a memory leak.

2022-09-21netfilter: conntrack: revisit the gc initial rescheduling biasAntoine Tenart
The previous commit changed the way the rescheduling delay is computed which has a side effect: the bias is now represented as much as the other entries in the rescheduling delay which makes the logic to kick in only with very large sets, as the initial interval is very large (INT_MAX). Revisit the GC initial bias to allow more frequent GC for smaller sets while still avoiding wakeups when a machine is mostly idle. We're moving from a large initial value to pretending we have 100 entries expiring at the upper bound. This way only a few entries having a small timeout won't impact much the rescheduling delay and non-idle machines will have enough entries to lower the delay when needed. This also improves readability as the initial bias is now linked to what is computed instead of being an arbitrary large value.

2022-09-21netfilter: conntrack: fix the gc rescheduling delayAntoine Tenart
Commit 2cfadb761d3d ("netfilter: conntrack: revisit gc autotuning") changed the eviction rescheduling to the use average expiry of scanned entries (within 1-60s) by doing: for (...) { expires = clamp(nf_ct_expires(tmp), ...); next_run += expires; next_run /= 2; } The issue is the above will make the average ('next_run' here) more dependent on the last expiration values than the firsts (for sets > 2). Depending on the expiration values used to compute the average, the result can be quite different than what's expected. To fix this we can do the following: for (...) { expires = clamp(nf_ct_expires(tmp), ...); next_run += (expires - next_run) / ++count; } Fixes: 2cfadb761d3d ("netfilter: conntrack: revisit gc autotuning") Cc: Florian Westphal <fw@strlen.de> Signed-off-by: Antoine Tenart <atenart@kernel.org> Signed-off-by: Florian Westphal <fw@strlen.de>

2022-09-21can: flexcan: flexcan_mailbox_read() fix return value for drop = trueMarc Kleine-Budde
The following happened on an i.MX25 using flexcan with many packets on the bus: The rx-offload queue reached a length more than skb_queue_len_max. In can_rx_offload_offload_one() the drop variable was set to true which made the call to .mailbox_read() (here: flexcan_mailbox_read()) to _always_ return ERR_PTR(-ENOBUFS) and drop the rx'ed CAN frame. So can_rx_offload_offload_one() returned ERR_PTR(-ENOBUFS), too. can_rx_offload_irq_offload_fifo() looks as follows: | while (1) { | skb = can_rx_offload_offload_one(offload, 0); | if (IS_ERR(skb)) | continue; | if (!skb) | break; | ... | } The flexcan driver wrongly always returns ERR_PTR(-ENOBUFS) if drop is requested, even if there is no CAN frame pending. As the i.MX25 is a single core CPU, while the rx-offload processing is active, there is no thread to process packets from the offload queue. So the queue doesn't get any shorter and this results is a tight loop. Instead of always returning ERR_PTR(-ENOBUFS) if drop is requested, return NULL if no CAN frame is pending. Changes since v1: https://lore.kernel.org/all/20220810144536.389237-1-u.kleine-koenig@pengutronix.de - don't break in can_rx_offload_irq_offload_fifo() in case of an error, return NULL in flexcan_mailbox_read() in case of no pending CAN frame instead Fixes: 4e9c9484b085 ("can: rx-offload: Prepare for CAN FD support") Link: https://lore.kernel.org/all/20220811094254.1864367-1-mkl@pengutronix.de Cc: stable@vger.kernel.org # v5.5 Suggested-by: Uwe Kleine-König <u.kleine-koenig@pengutronix.de> Reviewed-by: Uwe Kleine-König <u.kleine-koenig@pengutronix.de> Tested-by: Thorsten Scherer <t.scherer@eckelmann.de> Signed-off-by: Marc Kleine-Budde <mkl@pengutronix.de>

2022-09-21arch: um: Mark the stack non-executable to fix a binutils warningDavid Gow
Since binutils 2.39, ld will print a warning if any stack section is executable, which is the default for stack sections on files without a .note.GNU-stack section. This was fixed for x86 in commit ffcf9c5700e4 ("x86: link vdso and boot with -z noexecstack --no-warn-rwx-segments"), but remained broken for UML, resulting in several warnings: /usr/bin/ld: warning: arch/x86/um/vdso/vdso.o: missing .note.GNU-stack section implies executable stack /usr/bin/ld: NOTE: This behaviour is deprecated and will be removed in a future version of the linker /usr/bin/ld: warning: .tmp_vmlinux.kallsyms1 has a LOAD segment with RWX permissions /usr/bin/ld: warning: .tmp_vmlinux.kallsyms1.o: missing .note.GNU-stack section implies executable stack /usr/bin/ld: NOTE: This behaviour is deprecated and will be removed in a future version of the linker /usr/bin/ld: warning: .tmp_vmlinux.kallsyms2 has a LOAD segment with RWX permissions /usr/bin/ld: warning: .tmp_vmlinux.kallsyms2.o: missing .note.GNU-stack section implies executable stack /usr/bin/ld: NOTE: This behaviour is deprecated and will be removed in a future version of the linker /usr/bin/ld: warning: vmlinux has a LOAD segment with RWX permissions Link both the VDSO and vmlinux with -z noexecstack, fixing the warnings about .note.GNU-stack sections. In addition, pass --no-warn-rwx-segments to dodge the remaining warnings about LOAD segments with RWX permissions in the kallsyms objects. (Note that this flag is apparently not available on lld, so hide it behind a test for BFD, which is what the x86 patch does.)

Zhengchao Shao says: ==================== refactor duplicate codes in the tc cls walk function The walk implementation of most tc cls modules is basically the same. That is, the values of count and skip are checked first. If count is greater than or equal to skip, the registered fn function is executed. Otherwise, increase the value of count. So the code can be refactored. Then use helper function to replace the code of each cls module in alphabetical order. The walk function is invoked during dump. Therefore, test cases related to the tdc filter need to be added. ==================== Link: https://lore.kernel.org/r/20220916020251.190097-1-shaozhengchao@huawei.com Signed-off-by: Jakub Kicinski <kuba@kernel.org>
