If BPF code contains unused BPF subprogram and there are no other subprogram calls (which can realistically happen in real-world applications given sufficiently smart Clang code optimizations), libbpf will erroneously assume that subprograms are entry-point programs and will attempt to load them with UNSPEC program type. Fix by not relying on subcall instructions and rather detect it based on the structure of BPF object's sections.

RTL8125B has same or similar short packet hw padding bug as RTL8168evl. The main workaround has been extended accordingly, however we have to disable also hw checksumming for short packets on affected new chip versions. Instead of checking for an affected chip version let's simply disable hw checksumming for short packets in general. v2: - remove the version checks and disable short packet hw csum in general - reflect this in commit title and message Fixes: 0439297b ("r8169: add support for RTL8125B") Signed-off-by: NHeiner Kallweit <hkallweit1@gmail.com> Link: https://lore.kernel.org/r/7fbb35f0-e244-ef65-aa55-3872d7d38698@gmail.comSigned-off-by: NJakub Kicinski <kuba@kernel.org>

The caller of rtl8169_tso_csum_v2() frees the skb if false is returned. eth_skb_pad() internally frees the skb on error what would result in a double free. Therefore use __skb_put_padto() directly and instruct it to not free the skb on error. Fixes: b423e9ae ("r8169: fix offloaded tx checksum for small packets.")

The current logic checks if the name of the BTF type passed in attach_btf_id starts with "bpf_lsm_", this is not sufficient as it also allows attachment to non-LSM hooks like the very function that performs this check, i.e. bpf_lsm_verify_prog. In order to ensure that this verification logic allows attachment to only LSM hooks, the LSM_HOOK definitions in lsm_hook_defs.h are used to generate a BTF_ID set. Upon verification, the attach_btf_id of the program being attached is checked for presence in this set.

This was due to the following kmemdup() in tpm_read_log_efi(): int tpm_read_log_efi(struct tpm_chip *chip) { ... /* malloc EventLog space */ log->bios_event_log = kmemdup(log_tbl->log, log_size, GFP_KERNEL); if (!log->bios_event_log) { ret = -ENOMEM; goto out; } ... } When log_size is zero, due to an empty event log from firmware, ZERO_SIZE_PTR is returned from kmemdup(). Upon a read of the binary_bios_measurements file, the tpm2_bios_measurements_start() function does not perform a ZERO_OR_NULL_PTR() check on the bios_event_log pointer before dereferencing it. Rather than add a ZERO_OR_NULL_PTR() check in functions that make use of the bios_event_log pointer, simply avoid creating the binary_bios_measurements_file as is done in other event log retrieval backends. Explicitly ignore all of the events in the final event log when the main event log is empty. The list of events in the final event log cannot be accurately parsed without referring to the first event in the main event log (the event log header) so the final event log is useless in such a situation.

There is a misconfiguration in the bios of the gpio pin used for the interrupt in the T490s. When interrupts are enabled in the tpm_tis driver code this results in an interrupt storm. This was initially reported when we attempted to enable the interrupt code in the tpm_tis driver, which previously wasn't setting a flag to enable it. Due to the reports of the interrupt storm that code was reverted and we went back to polling instead of using interrupts. Now that we know the T490s problem is a firmware issue, add code to check if the system is a T490s and disable interrupts if that is the case. This will allow us to enable interrupts for everyone else. If the user has a fixed bios they can force the enabling of interrupts with tpm_tis.interrupts=1 on the kernel command line.

Zero-fill element values for all other cpus than current, just as when not using prealloc. This is the only way the bpf program can ensure known initial values for all cpus ('onallcpus' cannot be set when coming from the bpf program). The scenario is: bpf program inserts some elements in a per-cpu map, then deletes some (or userspace does). When later adding new elements using bpf_map_update_elem(), the bpf program can only set the value of the new elements for the current cpu. When prealloc is enabled, previously deleted elements are re-used. Without the fix, values for other cpus remain whatever they were when the re-used entry was previously freed. A selftest is added to validate correct operation in above scenario as well as in case of LRU per-cpu map element re-use.

In functions mlx5e_route_lookup_ipv{4|6}() route_dev can be arbitrary net device and not necessary mlx5 eswitch port representor. As such, in order to ensure that route_dev is not destroyed concurrent the code needs either explicitly take reference to the device before releasing reference to rtable instance or ensure that caller holds rtnl lock. First approach is chosen as a fix since rtnl lock dependency was intentionally removed from mlx5 TC layer. To prevent unprotected usage of route_dev in encap code take a reference to the device before releasing rt. Don't save direct pointer to the device in mlx5_encap_entry structure and use ifindex instead. Modify users of route_dev pointer to properly obtain the net device instance from its ifindex.
