In myri10ge_sw_tso, the skb_list_walk_safe macro will set (curr) = (segs) and (next) = (curr)->next. If status!=0 is true, the memory pointed by curr and segs will be free by dev_kfree_skb_any(curr). But later, the segs is used by segs = segs->next and causes a uaf. As (next) = (curr)->next, my patch replaces seg->next to next.

Ido Schimmel says: ==================== mlxsw: spectrum: Fix ECN marking in tunnel decapsulation Patch #1 fixes a discrepancy between the software and hardware data paths with regards to ECN marking after decapsulation. See the changelog for a detailed description. Patch #2 extends the ECN decap test to cover all possible combinations of inner and outer ECN markings. The test passes over both data paths. v2: * Only set ECT(1) if inner is ECT(0) * Introduce a new helper to determine inner ECN. Share it between NVE and IP-in-IP tunnels * Extend the selftest ==================== Signed-off-by: -

Cited commit changed the behavior of the software data path with regards to the ECN marking of decapsulated packets. However, the commit did not change other callers of __INET_ECN_decapsulate(), namely mlxsw. The driver is using the function in order to ensure that the hardware and software data paths act the same with regards to the ECN marking of decapsulated packets. The discrepancy was uncovered by commit 5aa3c334 ("selftests: forwarding: vxlan_bridge_1d: Fix vxlan ecn decapsulate value") that aligned the selftest to the new behavior. Without this patch the selftest passes when used with veth pairs, but fails when used with mlxsw netdevs. Fix this by instructing the device to propagate the ECT(1) mark from the outer header to the inner header when the inner header is ECT(0), for both NVE and IP-in-IP tunnels. A helper is added in order not to duplicate the code between both tunnel types. Fixes: b7237487 ("tunnel: Propagate ECT(1) when decapsulating as recommended by RFC6040") Signed-off-by:

In commit ea780056 ("can: add optional DLC element to Classical CAN frame structure") the struct can_frame::can_dlc was put into an anonymous union with another u8 variable. For various reasons some members in struct can_frame and canfd_frame including the first 8 byes of data are expected to have the same memory layout. This is enforced by a BUILD_BUG_ON check in af_can.c. Since the above mentioned commit this check fails on ARM kernels compiled with the ARM OABI (which means CONFIG_AEABI not set). In this case -mabi=apcs-gnu is passed to the compiler, which leads to a structure size boundary of 32, instead of 8 compared to CONFIG_AEABI enabled. This means the the union in struct can_frame takes 4 bytes instead of the expected 1. Rong Chen illustrates the problem with pahole in the ARM OABI case: | struct can_frame { | canid_t can_id; /* 0 4 */ | union { | __u8 len; /* 4 1 */ | __u8 can_dlc; /* 4 1 */ | }; /* 4 4 */ | __u8 __pad; /* 8 1 */ | __u8 __res0; /* 9 1 */ | __u8 len8_dlc; /* 10 1 */ | | /* XXX 5 bytes hole, try to pack */ | | __u8 data[8] | __attribute__((__aligned__(8))); /* 16 8 */ | | /* size: 24, cachelines: 1, members: 6 */ | /* sum members: 19, holes: 1, sum holes: 5 */ | /* forced alignments: 1, forced holes: 1, sum forced holes: 5 */ | /* last cacheline: 24 bytes */ | } __attribute__((__aligned__(8))); Marking the anonymous union as __attribute__((packed)) fixes the BUILD_BUG_ON problem on these compilers.

Antoine Tenart says: ==================== net: do not modify the shared tunnel info when PMTU triggers an ICMP reply The series fixes an issue were a shared ip_tunnel_info is modified when PMTU triggers an ICMP reply in vxlan and geneve, making following packets in that flow to have a wrong destination address if the flow isn't updated. A detailled information is given in each of the two commits. This was tested manually with OVS and I ran the PTMU selftests with kmemleak enabled (all OK, none was skipped). ==================== Signed-off-by: -
Antoine Tenart authored
When the interface is part of a bridge or an Open vSwitch port and a packet exceed a PMTU estimate, an ICMP reply is sent to the sender. When using the external mode (collect metadata) the source and destination addresses are reversed, so that Open vSwitch can match the packet against an existing (reverse) flow. But inverting the source and destination addresses in the shared ip_tunnel_info will make following packets of the flow to use a wrong destination address (packets will be tunnelled to itself), if the flow isn't updated. Which happens with Open vSwitch, until the flow times out. Fixes this by uncloning the skb's ip_tunnel_info before inverting its source and destination addresses, so that the modification will only be made for the PTMU packet, not the following ones.

The xMII interface clock depends on the PHY interface (MII, RMII, RGMII) as well as the current link speed. Explicitly configure the GSWIP to automatically select the appropriate xMII interface clock. This fixes an issue seen by some users where ports using an external RMII or RGMII PHY were deaf (no RX or TX traffic could be seen). Most likely this is due to an "invalid" xMII clock being selected either by the bootloader or hardware-defaults. Fixes: 14fceff4 ("net: dsa: Add Lantiq / Intel DSA driver for vrx200") Signed-off-by:

The kernel test robot found that __kmap_local_sched_out() was not correctly skipping the guard pages when DEBUG_KMAP_LOCAL_FORCE_MAP was set.[1] This was due to DEBUG_HIGHMEM check being used. Change the configuration check to be correct.

Commit 34dc2efb ("memblock: fix section mismatch warning") marked memblock_bottom_up() and memblock_set_bottom_up() as __init, but they could be referenced from non-init functions like memblock_find_in_range_node() on architectures that enable CONFIG_ARCH_KEEP_MEMBLOCK. For such builds kernel test robot reports: WARNING: modpost: vmlinux.o(.text+0x74fea4): Section mismatch in reference from the function memblock_find_in_range_node() to the function .init.text:memblock_bottom_up() The function memblock_find_in_range_node() references the function __init memblock_bottom_up(). This is often because memblock_find_in_range_node lacks a __init annotation or the annotation of memblock_bottom_up is wrong. Replace __init annotations with __init_memblock annotations so that the appropriate section will be selected depending on CONFIG_ARCH_KEEP_MEMBLOCK.

Because memblock allocations are registered with kmemleak, the KFENCE pool was seen by kmemleak as one large object. Later allocations through kfence_alloc() that were registered with kmemleak via slab_post_alloc_hook() would then overlap and trigger a warning. Therefore, once the pool is initialized, we can remove (free) it from kmemleak again, since it should be treated as allocator-internal and be seen as "free memory". The second problem is that kmemleak is passed the rounded size, and not the originally requested size, which is also the size of KFENCE objects. To avoid kmemleak scanning past the end of an object and trigger a KFENCE out-of-bounds error, fix the size if it is a KFENCE object. For simplicity, to avoid a call to kfence_ksize() in slab_post_alloc_hook() (and avoid new IS_ENABLED(CONFIG_DEBUG_KMEMLEAK) guard), just call kfence_ksize() in mm/kmemleak.c:create_object().
