      bpf: Update verification logic for LSM programs · 6f64e477
      KP Singh authored
      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.
      
      Fixes: 9e4e01df ("bpf: lsm: Implement attach, detach and execution")

        Sardine) so it shouldn't have much side effects.

      tpm: efi: Don't create binary_bios_measurements file for an empty log · 8ffd778a

      Mimic the pre-existing ACPI and Device Tree event log behavior by not
      creating the binary_bios_measurements file when the EFI TPM event log is
      empty.

      In this situation, the bios_event_log pointer in the tpm_bios_log struct
      was not NULL but was equal to the ZERO_SIZE_PTR (0x10) value. 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.
      
      Fixes: 58cc1e4f ("tpm: parse TPM event logs based on EFI table")

      tpm_tis: Disable interrupts on ThinkPad T490s · b154ce11
      Jerry Snitselaar authored
      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.

      bpf: Zero-fill re-used per-cpu map element · d3bec013
      David Verbeiren authored
      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.
