2023-05-24tipc: do not update mtu if msg_max is too small in mtu negotiationXin Long
[ Upstream commit 56077b56cd3fb78e1c8619e29581ba25a5c55e86 ] When doing link mtu negotiation, a malicious peer may send Activate msg with a very small mtu, e.g. 4 in Shuang's testing, without checking for the minimum mtu, l->mtu will be set to 4 in tipc_link_proto_rcv(), then n->links[bearer_id].mtu is set to 4294967228, which is a overflow of '4 - INT_H_SIZE - EMSG_OVERHEAD' in tipc_link_mss(). With tipc_link.mtu = 4, tipc_link_xmit() kept printing the warning: tipc: Too large msg, purging xmit list 1 5 0 40 4! tipc: Too large msg, purging xmit list 1 15 0 60 4! And with tipc_link_entry.mtu 4294967228, a huge skb was allocated in named_distribute(), and when purging it in tipc_link_xmit(), a crash was even caused: general protection fault, probably for non-canonical address 0x2100001011000dd: 0000 [#1] PREEMPT SMP PTI CPU: 0 PID: 0 Comm: swapper/0 Kdump: loaded Not tainted 6.3.0.neta #19 RIP: 0010:kfree_skb_list_reason+0x7e/0x1f0 Call Trace: <IRQ> skb_release_data+0xf9/0x1d0 kfree_skb_reason+0x40/0x100 tipc_link_xmit+0x57a/0x740 [tipc] tipc_node_xmit+0x16c/0x5c0 [tipc] tipc_named_node_up+0x27f/0x2c0 [tipc] tipc_node_write_unlock+0x149/0x170 [tipc] tipc_rcv+0x608/0x740 [tipc] tipc_udp_recv+0xdc/0x1f0 [tipc] udp_queue_rcv_one_skb+0x33e/0x620 udp_unicast_rcv_skb.isra.72+0x75/0x90 __udp4_lib_rcv+0x56d/0xc20 ip_protocol_deliver_rcu+0x100/0x2d0 This patch fixes it by checking the new mtu against tipc_bearer_min_mtu(), and not updating mtu if it is too small.

2023-05-24ASoC: mediatek: mt8186: Fix use-after-free in driver remove pathDouglas Anderson
[ Upstream commit a93d2afd3f77a7331271a0f25c6a11003db69b3c ] When devm runs function in the "remove" path for a device it runs them in the reverse order. That means that if you have parts of your driver that aren't using devm or are using "roll your own" devm w/ devm_add_action_or_reset() you need to keep that in mind. The mt8186 audio driver didn't quite get this right. Specifically, in mt8186_init_clock() it called mt8186_audsys_clk_register() and then went on to call a bunch of other devm function. The caller of mt8186_init_clock() used devm_add_action_or_reset() to call mt8186_deinit_clock() but, because of the intervening devm functions, the order was wrong. Specifically at probe time, the order was: 1. mt8186_audsys_clk_register() 2. afe_priv->clk = devm_kcalloc(...) 3. afe_priv->clk[i] = devm_clk_get(...) At remove time, the order (which should have been 3, 2, 1) was: 1. mt8186_audsys_clk_unregister() 3. Free all of afe_priv->clk[i] 2. Free afe_priv->clk The above seemed to be causing a use-after-free. Luckily, it's easy to fix this by simply using devm more correctly. Let's move the devm_add_action_or_reset() to the right place. In addition to fixing the use-after-free, code inspection shows that this fixes a leak (missing call to mt8186_audsys_clk_unregister()) that would have happened if any of the syscon_regmap_lookup_by_phandle() calls in mt8186_init_clock() had failed.

2023-05-24SUNRPC: always free ctxt when freeing deferred requestNeilBrown
[ Upstream commit 948f072ada23e0a504c5e4d7d71d4c83bd0785ec ] Since the ->xprt_ctxt pointer was added to svc_deferred_req, it has not been sufficient to use kfree() to free a deferred request. We may need to free the ctxt as well. As freeing the ctxt is all that ->xpo_release_rqst() does, we repurpose it to explicit do that even when the ctxt is not stored in an rqst. So we now have ->xpo_release_ctxt() which is given an xprt and a ctxt, which may have been taken either from an rqst or from a dreq. The caller is now responsible for clearing that pointer after the call to ->xpo_release_ctxt. We also clear dr->xprt_ctxt when the ctxt is moved into a new rqst when revisiting a deferred request. This ensures there is only one pointer to the ctxt, so the risk of double freeing in future is reduced. The new code in svc_xprt_release which releases both the ctxt and any rq_deferred depends on this.

2023-05-24SUNRPC: double free xprt_ctxt while still in useNeilBrown
[ Upstream commit eb8d3a2c809abd73ab0a060fe971d6b9019aa3c1 ] When an RPC request is deferred, the rq_xprt_ctxt pointer is moved out of the svc_rqst into the svc_deferred_req. When the deferred request is revisited, the pointer is copied into the new svc_rqst - and also remains in the svc_deferred_req. In the (rare?) case that the request is deferred a second time, the old svc_deferred_req is reused - it still has all the correct content. However in that case the rq_xprt_ctxt pointer is NOT cleared so that when xpo_release_xprt is called, the ctxt is freed (UDP) or possible added to a free list (RDMA). When the deferred request is revisited for a second time, it will reference this ctxt which may be invalid, and the free the object a second time which is likely to oops. So change svc_defer() to *always* clear rq_xprt_ctxt, and assert that the value is now stored in the svc_deferred_req.

However, while its name suggest that TX is totally disabled, it is not and can still allow to send BPDUs even if disabled.

[ Upstream commit 6d4486efe9c69626cab423456169e250a5cd3af5 ] When client and server establish a connection through vsock, the client send a request to the server to initiate the connection, then start a timer to wait for the server's response. When the server's RESPONSE message arrives, the timer also times out and exits. The server's RESPONSE message is processed first, and the connection is established. However, the client's timer also times out, the original processing logic of the client is to directly set the state of this vsock to CLOSE and return ETIMEDOUT. It will not notify the server when the port is released, causing the server port remain. when client's vsock_connect timeout，it should check sk state is ESTABLISHED or not. if sk state is ESTABLISHED, it means the connection is established, the client should not set the sk state to CLOSE Note: I encountered this issue on kernel-4.18, which can be fixed by this patch.

[ Upstream commit 21a933c79a33add3612808f3be4ad65dd4dc026b ] The srv6_end_dt4_l3vpn_test instantiates a virtual network consisting of several routers (rt-1, rt-2) and hosts. When the IPv6 addresses of rt-{1,2} routers are configured, the Deduplicate Address Detection (DAD) kicks in when enabled in the Linux distros running the selftests. DAD is used to check whether an IPv6 address is already assigned in a network. Such a mechanism consists of sending an ICMPv6 Echo Request and waiting for a reply. As the DAD process could take too long to complete, it may cause the failing of some tests carried out by the srv6_end_dt4_l3vpn_test script. To make the srv6_end_dt4_l3vpn_test more robust, we disable DAD on routers since we configure the virtual network manually and do not need any address deduplication mechanism at all.

[ Upstream commit c2adb1877b76fc81ae041e1db1a6ed2078c6746b ] System-wide TSC read could cause a drift in C0 percentage calculation. Because if first TSC is read and then one by one mperf is read for all cpus, this introduces drift between mperf reading of later CPUs and TSC reading. To lower this drift read TSC per CPU and also just after mperf read. This technique improves C0 percentage calculation in Mperf monitor.

2023-05-24platform: Provide a remove callback that returns no valueUwe Kleine-König
[ Upstream commit 5c5a7680e67ba6fbbb5f4d79fa41485450c1985c ] struct platform_driver::remove returning an integer made driver authors expect that returning an error code was proper error handling. However the driver core ignores the error and continues to remove the device because there is nothing the core could do anyhow and reentering the remove callback again is only calling for trouble. So this is an source for errors typically yielding resource leaks in the error path. As there are too many platform drivers to neatly convert them all to return void in a single go, do it in several steps after this patch: a) Convert all drivers to implement .remove_new() returning void instead of .remove() returning int; b) Change struct platform_driver::remove() to return void and so make it identical to .remove_new(); c) Change all drivers back to .remove() now with the better prototype; d) drop struct platform_driver::remove_new(). While this touches all drivers eventually twice, steps a) and c) can be done one driver after another and so reduces coordination efforts immensely and simplifies review.

2023-05-24drm/msm/dp: unregister audio driver during unbindSrinivas Kandagatla
[ Upstream commit 85c636284cb63b7740b4ae98881ace92158068d3 ] while binding the code always registers a audio driver, however there is no corresponding unregistration done in unbind. This leads to multiple redundant audio platform devices if dp_display_bind and dp_display_unbind happens multiple times during startup. On X13s platform this resulted in 6 to 9 audio codec device instead of just 3 codec devices for 3 dp ports. Fix this by unregistering codecs on unbind.

2023-05-24Revert "Fix XFRM-I support for nested ESP tunnels"Martin Willi
[ Upstream commit 5fc46f94219d1d103ffb5f0832be9da674d85a73 ] This reverts commit b0355dbbf13c0052931dd14c38c789efed64d3de. The reverted commit clears the secpath on packets received via xfrm interfaces to support nested IPsec tunnels. This breaks Netfilter policy matching using xt_policy in the FORWARD chain, as the secpath is missing during forwarding. Additionally, Benedict Wong reports that it breaks Transport-in-Tunnel mode. Fix this regression by reverting the commit until we have a better approach for nested IPsec tunnels.

[ Upstream commit 430cac487400494c19a8b85299e979bb07b4671f ] The current code doesn't let a simple "allow" policy counteract a default policy blocking all incoming packets: ip x p setdefault in block ip x p a src 192.168.2.1/32 dst 192.168.2.2/32 dir in action allow At this stage, we have an allow policy (with or without transforms) for this packet. It doesn't matter what the default policy says, since the policy we looked up lets the packet through. The case of a blocking policy is already handled separately, so we can remove this check.

2023-05-24parisc: Replace regular spinlock with spin_trylock on panic pathGuilherme G. Piccoli
[ Upstream commit 829632dae8321787525ee37dc4828bbe6edafdae ] The panic notifiers' callbacks execute in an atomic context, with interrupts/preemption disabled, and all CPUs not running the panic function are off, so it's very dangerous to wait on a regular spinlock, there's a risk of deadlock. Refactor the panic notifier of parisc/power driver to make use of spin_trylock - for that, we've added a second version of the soft-power function. Also, some comments were reorganized and trailing white spaces, useless header inclusion and blank lines were removed. Cc: "James E.J.
