2020-11-06tpm: efi: Don't create binary_bios_measurements file for an empty logTyler Hicks
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.

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.

2020-11-06tpm_tis: Disable interrupts on ThinkPad T490sJerry Snitselaar
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.

2020-11-05bpf: Zero-fill re-used per-cpu map elementDavid Verbeiren
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.

2020-11-05net/mlx5e: Protect encap route dev from concurrent releaseVlad Buslov
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.

2020-11-04PCI: mvebu: Fix duplicate resource requestsRob Herring
With commit 669cbc708122 ("PCI: Move DT resource setup into devm_pci_alloc_host_bridge()"), the DT 'ranges' is parsed and populated into resources when the host bridge is allocated. The resources are requested as well, but that happens a second time for the mvebu driver in mvebu_pcie_parse_request_resources(). We should only be requesting the additional resources added in mvebu_pcie_parse_request_resources(). These are not added by default because they use custom properties rather than standard DT address translation. Also, the bus ranges was also populated by default, so we can remove it from mvebu_pci_host_probe().

2020-11-04PCI: dwc: Restore ATU memory resource setup to use last entryRob Herring
Prior to commit 0f71c60ffd26 ("PCI: dwc: Remove storing of PCI resources"), the DWC driver was setting up the last memory resource rather than the first memory resource. This doesn't matter for most platforms which only have 1 memory resource, but it broke Tegra194 which has a 2nd (prefetchable) memory region that requires an ATU entry. The first region on Tegra194 relies on the default 1:1 pass-thru of outbound transactions and doesn't need an ATU entry.

Zhang Changzhong's patch fixes a remove_proc_entry warning in the AF_CAN core. A patch by me fixes a kfree_skb() call from IRQ context in the rx-offload helper. Vincent Mailhol contributes a patch to prevent a call to kfree_skb() in hard IRQ context in can_get_echo_skb(). Oliver Hartkopp's patch fixes the length calculation for RTR CAN frames in the __can_get_echo_skb() helper. Oleksij Rempel's patch fixes a use-after-free that shows up with j1939 in can_create_echo_skb(). Yegor Yefremov contributes 4 patches to enhance the j1939 documentation. Zhang Changzhong's patch fixes a hanging task problem in j1939_sk_bind() if the netdev is down. Then there are three patches for the newly added CAN_ISOTP protocol. Geert Uytterhoeven enhances the kconfig help text. Oliver Hartkopp's patch adds missing RX timeout handling in listen-only mode and Colin Ian King's patch decreases the generated object code by 926 bytes. Zhang Changzhong contributes a patch for the ti_hecc driver that fixes the error path in the probe function. Navid Emamdoost's patch for the xilinx_can driver fixes the error handling in case of failing pm_runtime_get_sync(). There are two patches for the peak_usb driver. Dan Carpenter adds range checking in decode operations and Stephane Grosjean's patch fixes a timestamp wrapping problem. Stephane Grosjean's patch for th peak_canfd driver fixes echo management if loopback is on. The next three patches all target the mcp251xfd driver. The first one is by me and it increased the severity of CRC read error messages. The kernel test robot removes an unneeded semicolon and Tom Rix removes unneeded break in several switch-cases. The last 4 patches are by Joakim Zhang and target the flexcan driver, the first three fix ECC related device specific quirks for the LS1021A, LX2160A and the VF610 SoC.

2020-11-04kprobes: Tell lockdep about kprobe nestingSteven Rostedt (VMware)
Since the kprobe handlers have protection that prohibits other handlers from executing in other contexts (like if an NMI comes in while processing a kprobe, and executes the same kprobe, it will get fail with a "busy" return). Lockdep is unaware of this protection. Use lockdep's nesting api to differentiate between locks taken in INT3 context and other context to suppress the false warnings.
