[ Upstream commit 96b5b458 ] Setting connection tracking OVS flows and then setting non-CT flows that use tuple rewrite action (e.g. mod_tp_dst), causes the latter flows not being offloaded. Fix by using a stricter condition in modify_header_match_supported() to check tuple rewrite support only for flows with CT action. The check is factored out into standalone modify_tuple_supported() function to aid readability. Fixes: 7e36feeb ("net/mlx5e: CT: Don't offload tuple rewrites for established tuples") Signed-off-by:

[ Upstream commit 7d6c86e3 ] Currently, we support hardware offload only for MPLS over UDP. However, rules matching on MPLS parameters are now wrongly offloaded for regular MPLS, without actually taking the parameters into consideration when doing the offload. Fix it by rejecting such unsupported rules. Fixes: 72046a91 ("net/mlx5e: Allow to match on mpls parameters") Signed-off-by:

[ Upstream commit 5244f5e2 ] Because the PM-runtime status of the device is not updated in __rpm_callback(), attempts to suspend the suppliers of the given device triggered by the rpm_put_suppliers() call in there may cause a supplier to be suspended completely before the status of the consumer is updated to RPM_SUSPENDED, which is confusing. To avoid that (1) modify __rpm_callback() to only decrease the PM-runtime usage counter of each supplier and (2) make rpm_suspend() try to suspend the suppliers after changing the consumer's status to RPM_SUSPENDED, in analogy with the device's parent.

[ Upstream commit 141f8202 ] The ppos points to a position in the old kernel memory (and in case of arm64 in the crash kernel since elfcorehdr is passed as a segment). The function should update the ppos by the amount that was read. This bug is not exposed by accident, but other platforms update this value properly. So, fix it in ARM64 version of elfcorehdr_read() as well. Signed-off-by:

[ Upstream commit 2d0c418c ] During some of the error-exit paths it is possible that release_attributes_data() will get called multiple times, which results in exit_foo_attributes() getting called multiple times. Make it safe to call exit_foo_attributes() multiple times, avoiding double-free()s in this case. Note that release_attributes_data() really should only be called once during error-exit paths. This will be fixed in a separate patch and it is good to have the exit_foo_attributes() functions modified this way regardless.

[ Upstream commit d939cd96 ] On some system the WMI GUIDs used by dell-wmi-sysman are present but there are no enum type attributes, this causes init_bios_attributes() to return -ENODEV, after which sysman_init() does a "goto fail_create_group" and then calls release_attributes_data(). release_attributes_data() calls kset_unregister(wmi_priv.main_dir_kset); but before this commit it was missing a "wmi_priv.main_dir_kset = NULL;" statement; and after calling release_attributes_data() the sysman_init() error handling does this: if (wmi_priv.main_dir_kset) { kset_unregister(wmi_priv.main_dir_kset); wmi_priv.main_dir_kset = NULL; } Which causes a second kset_unregister(wmi_priv.main_dir_kset), leading to a double-free, which causes a crash. Add the missing "wmi_priv.main_dir_kset = NULL;" statement to release_attributes_data() to fix this double-free crash.

[ Upstream commit b5f020f8 ] Commit d4eb538e ("can: isotp: TX-path: ensure that CAN frame flags are initialized") ensured the TX flags to be properly set for outgoing CAN frames. In fact the root cause of the issue results from a missing initialization of outgoing CAN frames created by isotp. This is no problem on the CAN bus as the CAN driver only picks the correctly defined content from the struct can(fd)_frame. But when the outgoing frames are monitored (e.g. with candump) we potentially leak some bytes in the unused content of struct can(fd)_frame.

In the DWARF generated by clang, struct outer appears before struct inner, so when converting BTF of struct outer into C, bpftool issues a forward declaration to struct inner. With GCC the DWARF info is reversed so struct inner gets fully defined. That forward declaration is not sufficient when compilers handle an array of the struct, even when it's only used through a pointer. Note that we can trigger the same issue with an intermediate typedef: struct inner { int val; }; typedef struct inner inner2_t[2]; struct outer { inner2_t *ptr_to_array; } A; Becomes: struct inner; typedef struct inner inner2_t[2]; And causes: ./def-clang.h:10:30: error: array has incomplete element type 'struct inner' typedef struct inner inner2_t[2]; To fix this, clear through_ptr whenever we encounter an intermediate array, to make the inner struct part of a strong link and force full declaration.

[ Upstream commit f91a50d8 ] If the USB host controller is EHCI, the throughput is reduced from 300Mb/s to 60Mb/s, when the rx buffer size is modified from 16K to 32K. According to the EHCI spec, the maximum size of the qTD is 20K. Therefore, when the driver uses more than 20K buffer, the latency time of EHCI would be increased. And, it let the RTL8153A get worse throughput. However, the driver uses alloc_pages() for rx buffer, so I limit the rx buffer to 16K rather than 20K.

[ Upstream commit 6c015a22 ] __dev_alloc_name(), when supplied with a name containing '%d', will search for the first available device number to generate a unique device name. Since commit ff927412 ("net: introduce name_node struct to be used in hashlist") network devices may have alternate names. __dev_alloc_name() does take these alternate names into account, possibly generating a name that is already taken and failing with -ENFILE as a result. This demonstrates the bug: # rmmod dummy 2>/dev/null # ip link property add dev lo altname dummy0 # modprobe dummy numdummies=1 modprobe: ERROR: could not insert 'dummy': Too many open files in system Instead of creating a device named dummy1, modprobe fails. Fix this by checking all the names in the d->name_node list, not just d->name. Signed-off-by:

[ Upstream commit 64451b98 ] unmapping npc counter works in a way by traversing all mcam entries to find which mcam rule is associated with counter. But loop cursor variable 'entry' is not incremented before checking next mcam entry which resulting in infinite loop. This in turn hogs the kworker thread forever and no other mbox message is processed by AF driver after that. Fix this by updating entry value before checking next mcam entry.

[ Upstream commit ce86c2a5 ] The MKEX profile describes what packet fields need to be extracted from the input packet and how to place those packet fields in the output key for MCAM matching. The MKEX profile can be in a way where higher layer packet fields can overwrite lower layer packet fields in output MCAM Key. Hence MKEX profile is always ensured that there are no overlaps between any of the layers. But the commit 42006910 ("octeontx2-af: cleanup KPU config data") introduced TX TOS field which overlaps with DMAC in MCAM key. This led to AF driver returning error when TX rule is installed with DMAC as match criteria since DMAC gets overwritten and cannot be supported. This patch fixes the issue by removing TOS field from MKEX TX profile. Fixes: 42006910 ("octeontx2-af: cleanup KPU config data") Signed-off-by:

[ Upstream commit dcc32f4f ] This reverts commit 6af1799a. Commit 6af1799a ("ipv6: drop incoming packets having a v4mapped source address") introduced an input check against v4mapped addresses. Use of such addresses on the wire is indeed questionable and not allowed on public Internet. As the commit pointed out https://tools.ietf.org/html/draft-itojun-v6ops-v4mapped-harmful-02 lists potential issues. Unfortunately there are applications which use v4mapped addresses, and breaking them is a clear regression. For example v4mapped addresses (or any semi-valid addresses, really) may be used for uni-direction event streams or packet export. Since the issue which sparked the addition of the check was with TCP and request_socks in particular push the check down to TCPv6 and DCCP. This restores the ability to receive UDPv6 packets with v4mapped address as the source. Keep using the IPSTATS_MIB_INHDRERRORS statistic to minimize the user-visible changes.
