2023-08-03netfilter: nf_tables: skip immediate deactivate in _PREPARE_ERRORPablo Neira Ayuso1-9/+18
[ Upstream commit 0a771f7b266b02d262900c75f1e175c7fe76fec2 ] On error when building the rule, the immediate expression unbinds the chain, hence objects can be deactivated by the transaction records. Otherwise, it is possible to trigger the following warning: WARNING: CPU: 3 PID: 915 at net/netfilter/nf_tables_api.c:2013 nf_tables_chain_destroy+0x1f7/0x210 [nf_tables] CPU: 3 PID: 915 Comm: chain-bind-err- Not tainted 6.1.39 #1 RIP: 0010:nf_tables_chain_destroy+0x1f7/0x210 [nf_tables] Fixes: 4bedf9eee016 ("netfilter: nf_tables: fix chain binding transaction logic") Reported-by: Kevin Rich <kevinrich1337@gmail.com> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org> Signed-off-by: Florian Westphal <fw@strlen.de> Signed-off-by: Sasha Levin <sashal@kernel.org>
2023-08-03netfilter: nft_set_rbtree: fix overlap expiration walkFlorian Westphal1-6/+14
[ Upstream commit f718863aca469a109895cb855e6b81fff4827d71 ] The lazy gc on insert that should remove timed-out entries fails to release the other half of the interval, if any. Can be reproduced with tests/shell/testcases/sets/0044interval_overlap_0 in nftables.git and kmemleak enabled kernel. Second bug is the use of rbe_prev vs. prev pointer. If rbe_prev() returns NULL after at least one iteration, rbe_prev points to element that is not an end interval, hence it should not be removed. Lastly, check the genmask of the end interval if this is active in the current generation.

2023-08-03igc: Fix Kernel Panic during ndo_tx_timeout callbackMuhammad Husaini Zulkifli1-12/+28
[ Upstream commit d4a7ce642100765119a872d4aba1bf63e3a22c8a ] The Xeon validation group has been carrying out some loaded tests with various HW configurations, and they have seen some transmit queue time out happening during the test. This will cause the reset adapter function to be called by igc_tx_timeout(). Similar race conditions may arise when the interface is being brought down and up in igc_reinit_locked(), an interrupt being generated, and igc_clean_tx_irq() being called to complete the TX. When the igc_tx_timeout() function is invoked, this patch will turn off all TX ring HW queues during igc_down() process. TX ring HW queues will be activated again during the igc_configure_tx_ring() process when performing the igc_up() procedure later. This patch also moved existing igc_disable_tx_ring_hw() to avoid using forward declaration.

2023-08-03macvlan: add forgotten nla_policy for IFLA_MACVLAN_BC_CUTOFFLin Ma1-0/+1
[ Upstream commit 55cef78c244d0d076f5a75a35530ca63c92f4426 ] The previous commit 954d1fa1ac93 ("macvlan: Add netlink attribute for broadcast cutoff") added one additional attribute named IFLA_MACVLAN_BC_CUTOFF to allow broadcast cutfoff. However, it forgot to describe the nla_policy at macvlan_policy (drivers/net/macvlan.c). Hence, this suppose NLA_S32 (4 bytes) integer can be faked as empty (0 bytes) by a malicious user, which could leads to OOB in heap just like CVE-2023-3773. To fix it, this commit just completes the nla_policy description for IFLA_MACVLAN_BC_CUTOFF. This enforces the length check and avoids the potential OOB read.

2023-08-03x86/traps: Fix load_unaligned_zeropad() handling for shared TDX memoryKirill A. Shutemov1-7/+11
[ Upstream commit 9f9116406120638b4d8db3831ffbc430dd2e1e95 ] Commit c4e34dd99f2e ("x86: simplify load_unaligned_zeropad() implementation") changes how exceptions around load_unaligned_zeropad() handled. The kernel now uses the fault_address in fixup_exception() to verify the address calculations for the load_unaligned_zeropad(). It works fine for #PF, but breaks on #VE since no fault address is passed down to fixup_exception(). Propagating ve_info.gla down to fixup_exception() resolves the issue.

2023-08-03platform/x86: msi-laptop: Fix rfkill out-of-sync on MSI Wind U100Maxim Mikityanskiy1-4/+4
[ Upstream commit ad084a6d99bc182bf109c190c808e2ea073ec57b ] Only the HW rfkill state is toggled on laptops with quirks->ec_read_only (so far only MSI Wind U90/U100). There are, however, a few issues with the implementation: 1. The initial HW state is always unblocked, regardless of the actual state on boot, because msi_init_rfkill only sets the SW state, regardless of ec_read_only. 2. The initial SW state corresponds to the actual state on boot, but it can't be changed afterwards, because set_device_state returns -EOPNOTSUPP. It confuses the userspace, making Wi-Fi and/or Bluetooth unusable if it was blocked on boot, and breaking the airplane mode if the rfkill was unblocked on boot. Address the above issues by properly initializing the HW state on ec_read_only laptops and by allowing the userspace to toggle the SW state. Don't set the SW state ourselves and let the userspace fully control it. Toggling the SW state is a no-op, however, it allows the userspace to properly toggle the airplane mode. The actual SW radio disablement is handled by the corresponding rtl818x_pci and btusb drivers that have their own rfkills. Tested on MSI Wind U100 Plus, BIOS ver 1.0G, EC ver 130.

2023-08-03net: stmmac: Apply redundant write work around on 4.xx tooVincent Whitchurch1-1/+3
[ Upstream commit 284779dbf4e98753458708783af8c35630674a21 ] commit a3a57bf07de23fe1ff779e0fdf710aa581c3ff73 ("net: stmmac: work around sporadic tx issue on link-up") worked around a problem with TX sometimes not working after a link-up by avoiding a redundant write to MAC_CTRL_REG (aka GMAC_CONFIG), since the IP appeared to have problems with handling multiple writes to that register in some cases. That commit however only added the work around to dwmac_lib.c (apart from the common code in stmmac_main.c), but my systems with version 4.21a of the IP exhibit the same problem, so add the work around to dwmac4_lib.c too.

Because of which we are facing initialization issues when the silicon does not support hash extraction. During creation of the hardware parsing table for IPv6 address, we need to consider if hash extraction is enabled then extract only 32 bit, otherwise 128 bit needs to be extracted.

2023-08-03tcp: Reduce chance of collisions in inet6_hashfn().Stewart Smith1-6/+2
[ Upstream commit d11b0df7ddf1831f3e170972f43186dad520bfcc ] For both IPv4 and IPv6 incoming TCP connections are tracked in a hash table with a hash over the source & destination addresses and ports. However, the IPv6 hash is insufficient and can lead to a high rate of collisions. The IPv6 hash used an XOR to fit everything into the 96 bits for the fast jenkins hash, meaning it is possible for an external entity to ensure the hash collides, thus falling back to a linear search in the bucket, which is slow. We take the approach of hash the full length of IPv6 address in __ipv6_addr_jhash() so that all users can benefit from a more secure version. While this may look like it adds overhead, the reality of modern CPUs means that this is unmeasurable in real world scenarios. In simulating with llvm-mca, the increase in cycles for the hashing code was ~16 cycles on Skylake (from a base of ~155), and an extra ~9 on Nehalem (base of ~173). In commit dd6d2910c5e0 ("netfilter: conntrack: switch to siphash") netfilter switched from a jenkins hash to a siphash, but even the faster hsiphash is a more significant overhead (~20-30%) in some preliminary testing. So, in this patch, we keep to the more conservative approach to ensure we don't add much overhead per SYN. In testing, this results in a consistently even spread across the connection buckets. In both testing and real-world scenarios, we have not found any measurable performance impact.

[ Upstream commit bb7a0156365dffe2fcd63e2051145fbe4f8908b4 ] According to the implementation of XDP of FEC driver, the XDP path shares the transmit queues with the kernel network stack, so it is possible to lead to a tx timeout event when XDP uses the tx queue pretty much exclusively. And this event will cause the reset of the FEC hardware. To avoid timeout in this case, we use the txq_trans_cond_update() interface to update txq->trans_start to jiffies so that watchdog won't generate a transmit timeout warning.

2023-08-03vxlan: calculate correct header length for GPEJiri Benc3-18/+20
[ Upstream commit 94d166c5318c6edd1e079df8552233443e909c33 ] VXLAN-GPE does not add an extra inner Ethernet header. Take that into account when calculating header length. This causes problems in skb_tunnel_check_pmtu, where incorrect PMTU is cached. In the collect_md mode (which is the only mode that VXLAN-GPE supports), there's no magic auto-setting of the tunnel interface MTU. It can't be, since the destination and thus the underlying interface may be different for each packet. So, the administrator is responsible for setting the correct tunnel interface MTU. Apparently, the administrators are capable enough to calculate that the maximum MTU for VXLAN-GPE is (their_lower_MTU - 36). They set the tunnel interface MTU to 1464. If you run a TCP stream over such interface, it's then segmented according to the MTU 1464, i.e. producing 1514 bytes frames. Which is okay, this still fits the lower MTU. However, skb_tunnel_check_pmtu (called from vxlan_xmit_one) uses 50 as the header size and thus incorrectly calculates the frame size to be 1528. This leads to ICMP too big message being generated (locally), PMTU of 1450 to be cached and the TCP stream to be resegmented. The fix is to use the correct actual header size, especially for skb_tunnel_check_pmtu calculation.

[ Upstream commit 8a0eb8f9b9a002291a3934acfd913660b905249e ] The driver is not enabling the ref clock, which thus gets disabled by the clk_disable_unused() initcall. This leads to the dwc3 controller failing to initialize if probed after clk_disable_unused() is called, for instance when the driver is built as a module. To fix this, switch to the clk_bulk API to handle both cfg_ahb and ref clocks at the proper places. Note that the cfg_ahb clock is currently not used by any device tree instantiation of the PHY. Work needs to be done separately to fix this.

2023-08-03phy: qcom-snps-femto-v2: keep cfg_ahb_clk enabled during runtime suspendAdrien Thierry1-9/+0
[ Upstream commit 45d89a344eb46db9dce851c28e14f5e3c635c251 ] In the dwc3 core, both system and runtime suspend end up calling dwc3_suspend_common(). From there, what happens for the PHYs depends on the USB mode and whether the controller is entering system or runtime suspend. HOST mode: (1) system suspend on a non-wakeup-capable controller The [1] if branch is taken. dwc3_core_exit() is called, which ends up calling phy_power_off() and phy_exit(). Those two functions decrease the PM runtime count at some point, so they will trigger the PHY runtime sleep (assuming the count is right). (2) runtime suspend / system suspend on a wakeup-capable controller The [1] branch is not taken. dwc3_suspend_common() calls phy_pm_runtime_put_sync(). Assuming the ref count is right, the PHY runtime suspend op is called. DEVICE mode: dwc3_core_exit() is called on both runtime and system sleep unless the controller is already runtime suspended. OTG mode: (1) system suspend : dwc3_core_exit() is called (2) runtime suspend : do nothing In host mode, the code seems to make a distinction between 1) runtime sleep / system sleep for wakeup-capable controller, and 2) system sleep for non-wakeup-capable controller, where phy_power_off() and phy_exit() are only called for the latter. This suggests the PHY is not supposed to be in a fully powered-off state for runtime sleep and system sleep for wakeup-capable controller. Moreover, downstream, cfg_ahb_clk only gets disabled for system suspend. The clocks are disabled by phy->set_suspend() [2] which is only called in the system sleep path through dwc3_core_exit() [3]. With that in mind, don't disable the clocks during the femto PHY runtime suspend callback. The clocks will only be disabled during system suspend for non-wakeup-capable controllers, through dwc3_core_exit().

2023-08-03ext4: fix rbtree traversal bug in ext4_mb_use_preallocatedOjaswin Mujoo1-27/+131
[ Upstream commit 9d3de7ee192a6a253f475197fe4d2e2af10a731f ] During allocations, while looking for preallocations(PA) in the per inode rbtree, we can't do a direct traversal of the tree because ext4_mb_discard_group_preallocation() can paralelly mark the pa deleted and that can cause direct traversal to skip some entries. This was leading to a BUG_ON() being hit [1] when we missed a PA that could satisfy our request and ultimately tried to create a new PA that would overlap with the missed one. To makes sure we handle that case while still keeping the performance of the rbtree, we make use of the fact that the only pa that could possibly overlap the original goal start is the one that satisfies the below conditions: 1. It must have it's logical start immediately to the left of (ie less than) original logical start. 2. It must not be deleted To find this pa we use the following traversal method: 1. Descend into the rbtree normally to find the immediate neighboring PA. Here we keep descending irrespective of if the PA is deleted or if it overlaps with our request etc. The goal is to find an immediately adjacent PA. 2. If the found PA is on right of original goal, use rb_prev() to find the left adjacent PA. 3. Check if this PA is deleted and keep moving left with rb_prev() until a non deleted PA is found. 4. This is the PA we are looking for. Now we can check if it can satisfy the original request and proceed accordingly. This approach also takes care of having deleted PAs in the tree. (While we are at it, also fix a possible overflow bug in calculating the end of a PA) [1] https://lore.kernel.org/linux-ext4/CA+G9fYv2FRpLqBZf34ZinR8bU2_ZRAUOjKAD3+tKRFaEQHtt8Q@mail.gmail.com/ Cc: stable@kernel.org # 6.4 Fixes: 3872778664e3 ("ext4: Use rbtrees to manage PAs instead of inode i_prealloc_list") Signed-off-by: Ojaswin Mujoo <ojaswin@linux.ibm.com> Reported-by: Naresh Kamboju <naresh.kamboju@linaro.org> Reviewed-by: Ritesh Harjani (IBM) ritesh.list@gmail.com Tested-by: Ritesh Harjani (IBM) ritesh.list@gmail.com Link: https://lore.kernel.org/r/edd2efda6a83e6343c5ace9deea44813e71dbe20.1690045963.git.ojaswin@linux.ibm.com Signed-off-by: Theodore Ts'o <tytso@mit.edu> Signed-off-by: Sasha Levin <sashal@kernel.org>

[ Upstream commit 469a62938a45ef382c9cb7b9fec6c6c1fcd781c0 ] [Why] Flickering and underflow was observed when testing extended blank on dcn314. [What] Vstartup is contrainted by vblank_nom, so adjusting it to include non-adjusted vtotal in its calculation during freesync video means that Vstartup is not changed when vtotal changes. This fixed the flickering + underflow. dc_extended_blank_supported function was removed because extended blank is only relevant to when zstate is supported. The increased vtotal during freesync can be passed to dml regardless of whether extended blank is supported or not, so this function is not needed. Updates were made recently in dml to the calculation of min_dst_y_next_start. Dml input for dcn314 will now always use the newer calculation for min_dst_y_next_start. Dml input for older dcn versions remains untouched. The variable optimized_min_dst_y_next_start is replaced everywhere with min_dst_y_next_start, and the updated dml allows min_dst_y_next_start to increase to an optimized value during freesync video, then return to default when freesync is disengaged.

2023-08-03maple_tree: add __init and __exit to test moduleLiam R. Howlett3-151/+155
[ Upstream commit eaf9790d3bc6e157a2134c01c7d707a5a712fab1 ] The test functions are not needed after the module is removed, so mark them as such. Add __exit to the module removal function. Some other variables have been marked as const static as well. Link: https://lkml.kernel.org/r/20230518145544.1722059-20-Liam.Howlett@oracle.com Signed-off-by: Liam R.

[ Upstream commit cd2e31a9ab93d13c412a36c6e26811e0f830985b ] The same parade TCON issue can potentially happen on Phoenix, and the same PSR resilience changes have been ported into the DMUB firmware. Don't allow running PSR-SU unless on the newer firmware.

[ Upstream commit c35b6ea8f2ecfa9d775530b70d4e727869099a9c ] A number of parade TCONs are causing system hangs when utilized with older DMUB firmware and PSR-SU. Some changes have been introduced into DMUB firmware to add resilience against these failures. Don't allow running PSR-SU unless on the newer firmware.
