Some of the data types chosen for +this process are incorrectly too small, and can overflow. This can +result in the incorrect slice construction, which can lead to data +corruption in workload execution. + +The device can only handle 32-bit sized transfers, and the scatterlist +struct only supports 32-bit buffer sizes, so our upper limit for an +individual transfer is an unsigned int. Using an int is incorrect due to +the reservation of the sign bit. Upgrade the length of a scatterlist +entry and the offsets into a scatterlist entry to unsigned int for a +correct representation. + +While each transfer may be limited to 32-bits, the overall BO may exceed +that size. For counting the total length of the BO, we need a type that +can represent the largest allocation possible on the system. That is the +definition of size_t, so use it. + +Fixes: ff13be830333 ("accel/qaic: Add datapath") +Signed-off-by: Jeffrey Hugo +Signed-off-by: Jeff Hugo +Reviewed-by: Lizhi Hou +Reviewed-by: Troy Hanson +Reviewed-by: Youssef Samir +Link: https://patchwork.freedesktop.org/patch/msgid/20250306171959.853466-1-jeff.hugo@oss.qualcomm.com +Signed-off-by: Sasha Levin +--- + drivers/accel/qaic/qaic_data.c | 5 ++++- + 1 file changed, 4 insertions(+), 1 deletion(-) + +diff --git a/drivers/accel/qaic/qaic_data.c b/drivers/accel/qaic/qaic_data.c +index d2f8c70a77a5b..e8e6eb85f5f13 100644 +--- a/drivers/accel/qaic/qaic_data.c ++++ b/drivers/accel/qaic/qaic_data.c +@@ -165,9 +165,10 @@ static void free_slice(struct kref *kref) + static int clone_range_of_sgt_for_slice(struct qaic_device *qdev, struct sg_table **sgt_out, + struct sg_table *sgt_in, u64 size, u64 offset) + { +- int total_len, len, nents, offf = 0, offl = 0; + struct scatterlist *sg, *sgn, *sgf, *sgl; ++ unsigned int len, nents, offf, offl; + struct sg_table *sgt; ++ size_t total_len; + int ret, j; + + /* find out number of relevant nents needed for this mem */ +@@ -175,6 +176,8 @@ static int clone_range_of_sgt_for_slice(struct qaic_device *qdev, struct sg_tabl + sgf = NULL; + sgl = NULL; + nents = 0; ++ offf = 0; ++ offl = 0; + + size = size ? size : PAGE_SIZE; + for_each_sgtable_dma_sg(sgt_in, sg, j) { +-- +2.39.5 + diff --git a/queue-6.6/arm-davinci-da850-fix-selecting-arch_davinci_da8xx.patch b/queue-6.6/arm-davinci-da850-fix-selecting-arch_davinci_da8xx.patch new file mode 100644 index 0000000000..e854208210 --- /dev/null +++ b/queue-6.6/arm-davinci-da850-fix-selecting-arch_davinci_da8xx.patch @@ -0,0 +1,38 @@ +From bb52957c37074609421b8093fe23e62e444b80ed Mon Sep 17 00:00:00 2001 +From: Sasha Levin +Date: Mon, 1 Apr 2024 10:09:46 -0500 +Subject: ARM: davinci: da850: fix selecting ARCH_DAVINCI_DA8XX + +From: David Lechner + +[ Upstream commit 45d5fe1c53baaed1fb3043f45d1e15ebb4bbe86a ] + +Chips in the DA850 family need to have ARCH_DAVINCI_DA8XX to be selected +in order to enable some peripheral drivers. + +This was accidentally removed in a previous commit. + +Fixes: dec85a95167a ("ARM: davinci: clean up platform support") +Signed-off-by: David Lechner +Acked-by: Bartosz Golaszewski +Signed-off-by: Arnd Bergmann +Signed-off-by: Sasha Levin +--- + arch/arm/mach-davinci/Kconfig | 1 + + 1 file changed, 1 insertion(+) + +diff --git a/arch/arm/mach-davinci/Kconfig b/arch/arm/mach-davinci/Kconfig +index 2a8a9fe46586d..3fa15f3422409 100644 +--- a/arch/arm/mach-davinci/Kconfig ++++ b/arch/arm/mach-davinci/Kconfig +@@ -27,6 +27,7 @@ config ARCH_DAVINCI_DA830 + + config ARCH_DAVINCI_DA850 + bool "DA850/OMAP-L138/AM18x based system" ++ select ARCH_DAVINCI_DA8XX + select DAVINCI_CP_INTC + + config ARCH_DAVINCI_DA8XX +-- +2.39.5 + diff --git a/queue-6.6/arm-dts-bcm2711-don-t-mark-timer-regs-unconfigured.patch b/queue-6.6/arm-dts-bcm2711-don-t-mark-timer-regs-unconfigured.patch new file mode 100644 index 0000000000..80dbf39f1c --- /dev/null +++ b/queue-6.6/arm-dts-bcm2711-don-t-mark-timer-regs-unconfigured.patch @@ -0,0 +1,44 @@ +From 6de06ab830fe1c73aa4c60fa85a0a2fbe42d8ab8 Mon Sep 17 00:00:00 2001 +From: Sasha Levin +Date: Sat, 22 Feb 2025 10:41:13 +0100 +Subject: ARM: dts: bcm2711: Don't mark timer regs unconfigured + +From: Phil Elwell + +[ Upstream commit c24f272ae751a9f54f8816430e7f2d56031892cc ] + +During upstream process of Raspberry Pi 4 back in 2019 the ARMv7 stubs +didn't configured the ARM architectural timer.

In general, such +loops are the consequence of pathological configurations. Each lwtunnel +user is still free to catch such loops early and do whatever they want +with them. It will be the case in a separate patch for, e.g., seg6 and +seg6_local, in order to provide drop reasons and update statistics. +Another example of a lwtunnel user taking care of loops is ioam6, which +has valid use cases that include loops (e.g., inline mode), and which is +addressed by the next patch in this series. Overall, this patch acts as +a last resort to catch loops and drop packets, since we don't want to +leak something unintentionally because of a pathological configuration +in lwtunnels. + +The solution in this patch reuses dev_xmit_recursion(), +dev_xmit_recursion_inc(), and dev_xmit_recursion_dec(), which seems fine +considering the context. + +Closes: https://lore.kernel.org/netdev/2bc9e2079e864a9290561894d2a602d6@akamai.com/ +Closes: https://lore.kernel.org/netdev/Z7NKYMY7fJT5cYWu@shredder/ +Fixes: ffce41962ef6 ("lwtunnel: support dst output redirect function") +Fixes: 2536862311d2 ("lwt: Add support to redirect dst.input") +Fixes: 14972cbd34ff ("net: lwtunnel: Handle fragmentation") +Signed-off-by: Justin Iurman +Link: https://patch.msgid.link/20250314120048.12569-2-justin.iurman@uliege.be +Signed-off-by: Paolo Abeni +Signed-off-by: Sasha Levin +--- + net/core/lwtunnel.c | 65 ++++++++++++++++++++++++++++++++++++--------- + 1 file changed, 53 insertions(+), 12 deletions(-) + +diff --git a/net/core/lwtunnel.c b/net/core/lwtunnel.c +index 711cd3b4347a7..4417a18b3e951 100644 +--- a/net/core/lwtunnel.c ++++ b/net/core/lwtunnel.c +@@ -23,6 +23,8 @@ + #include + #include + ++#include "dev.h" ++ + DEFINE_STATIC_KEY_FALSE(nf_hooks_lwtunnel_enabled);

Unfortunately, it is slightly broader than necessary, as it also +severely affects performance for Geneve + IPSec transport mode over a +device capable of both HW GSO and IPSec crypto offload. In this case, +xfrm_output unnecessarily triggers software GSO instead of letting the +HW do it. In simple iperf3 tests over Geneve + IPSec transport mode over +a back-2-back pair of NICs with MTU 1500, the performance was observed +to be up to 6x worse when doing software GSO compared to leaving it to +the hardware. + +This commit makes xfrm_output only trigger software GSO in crypto +offload cases for already encapsulated packets in tunnel mode, as not +doing so would then cause the inner tunnel skb->inner_networking_header +to be overwritten and break software GSO for that packet later if the +device turns out to not be capable of HW GSO. + +Taking a closer look at the conditions for the original bug, to better +understand the reasons for this change: +- vxlan_build_skb -> iptunnel_handle_offloads sets inner_protocol and + inner network header. +- then, udp_tunnel_xmit_skb -> ip_tunnel_xmit adds outer transport and + network headers. +- later in the xmit path, xfrm_output -> xfrm_outer_mode_output -> + xfrm4_prepare_output -> xfrm4_tunnel_encap_add overwrites the inner + network header with the one set in ip_tunnel_xmit before adding the + second outer header. +- __dev_queue_xmit -> validate_xmit_skb checks whether GSO segmentation + needs to happen based on dev features. In the original bug, the hw + couldn't segment the packets, so skb_gso_segment was invoked. +- deep in the .gso_segment callback machinery, __skb_udp_tunnel_segment + tries to use the wrong inner network header, expecting the one set in + iptunnel_handle_offloads but getting the one set by xfrm instead. +- a bit later, ipv6_gso_segment accesses the wrong memory based on that + wrong inner network header. + +With the new change, the original bug (or similar ones) cannot happen +again, as xfrm will now trigger software GSO before applying a tunnel. +This concern doesn't exist in packet offload mode, when the HW adds +encapsulation headers. For the non-offloaded packets (crypto in SW), +software GSO is still done unconditionally in the else branch. + +Reviewed-by: Dragos Tatulea +Reviewed-by: Yael Chemla +Reviewed-by: Leon Romanovsky +Fixes: a204aef9fd77 ("xfrm: call xfrm_output_gso when inner_protocol is set in xfrm_output") +Signed-off-by: Cosmin Ratiu +Signed-off-by: Steffen Klassert +Signed-off-by: Sasha Levin +--- + net/xfrm/xfrm_output.c | 2 +- + 1 file changed, 1 insertion(+), 1 deletion(-) + +diff --git a/net/xfrm/xfrm_output.c b/net/xfrm/xfrm_output.c +index 9160a5e09041d..a30538a980cc7 100644 +--- a/net/xfrm/xfrm_output.c ++++ b/net/xfrm/xfrm_output.c +@@ -793,7 +793,7 @@ int xfrm_output(struct sock *sk, struct sk_buff *skb) + skb->encapsulation = 1; + + if (skb_is_gso(skb)) { +- if (skb->inner_protocol) ++ if (skb->inner_protocol && x->props.mode == XFRM_MODE_TUNNEL) + return xfrm_output_gso(net, sk, skb); + + skb_shinfo(skb)->gso_type |= SKB_GSO_ESP; +-- +2.39.5 +
