2019-10-07ionic: fix stats memory dereferenceShannon Nelson
When the netdev is down, the queues and their debug stats do not exist, so don't try using a pointer to them when when printing the ethtool stats. Fixes: e470355bd96a ("ionic: Add driver stats") Signed-off-by: Shannon Nelson <snelson@pensando.io> Signed-off-by: David S. Miller <davem@davemloft.net>
2019-10-07net: ena: ethtool: support set_channels callbackSameeh Jubran
Set channels callback enables the user to change the count of queues used by the driver using ethtool. We decided to currently support only equal number of rx and tx queues, this might change in the future. Also rename dev_up to dev_was_up in ena_update_queue_count() to make it clearer.

- Update ena_ethtool:ena_get_channels() to return adapter->max_io_queues so that ethtool -l returns the correct maximum queue number. - Change the name of ena_calc_io_queue_num() to ena_calc_max_io_queue_num() as it returns the maximum number of io queues and actual number of queues can be smaller if changed by ethtool -L which is implemented in a later commit. - Change variable name from io_queue_num to max_num_io_queues in ena_calc_max_io_queue_num() and ena_probe(). - Make all types of variables that convey the number and sizeof queues to be u32, for consistency with the API between the driver and the device.

2019-10-07efi/tpm: Only set 'efi_tpm_final_log_size' after successful event log parsingJerry Snitselaar
If __calc_tpm2_event_size() fails to parse an event it will return 0, resulting tpm2_calc_event_log_size() returning -1. Currently there is no check of this return value, and 'efi_tpm_final_log_size' can end up being set to this negative value resulting in a crash like this one: BUG: unable to handle page fault for address: ffffbc8fc00866ad #PF: supervisor read access in kernel mode #PF: error_code(0x0000) - not-present page RIP: 0010:memcpy_erms+0x6/0x10 Call Trace: tpm_read_log_efi() tpm_bios_log_setup() tpm_chip_register() tpm_tis_core_init.cold.9+0x28c/0x466 tpm_tis_plat_probe() platform_drv_probe() ... Also __calc_tpm2_event_size() returns a size of 0 when it fails to parse an event, so update function documentation to reflect this. The root cause of the issue that caused the failure of event parsing in this case is resolved by Peter Jone's patchset dealing with large event logs where crossing over a page boundary causes the page with the event count to be unmapped.

2019-10-07efi/tpm: Don't traverse an event log with no eventsPeter Jones
When there are no entries to put into the final event log, some machines will return the template they would have populated anyway. In this case the nr_events field is 0, but the rest of the log is just garbage.

2019-10-07efivar/ssdt: Don't iterate over EFI vars if no SSDT override was specifiedArd Biesheuvel
The kernel command line option efivar_ssdt= allows the name to be specified of an EFI variable containing an ACPI SSDT table that should be loaded into memory by the OS, and treated as if it was provided by the firmware. Currently, that code will always iterate over the EFI variables and compare each name with the provided name, even if the command line option wasn't set to begin with. So bail early when no variable name was provided. This works around a boot regression on the 2012 Mac Pro, as reported by Scott.

In the au1550nd driver we have 2 implementations of read_buf. The previously mentioned commit modified the au_read_buf() implementation to match the function pointer, but not au_read_buf16(). This results in a compiler warning for MIPS db1xxx_defconfig builds: drivers/mtd/nand/raw/au1550nd.c:443:57: warning: pointer type mismatch in conditional expression Fix this by updating the prototype of au_read_buf16() to take a struct nand_chip pointer as its first argument, as is expected after commit 7e534323c416 ("mtd: rawnand: Pass a nand_chip object to chip->read_xxx() hooks").

Use new field "num_of_modules" of MGPIR register for "hwmon" interface in order to get the number of modules supported by system directly from the system configuration, instead of getting it from port to module mapping info. Reading this info through MGPIR register is faster and does not depend on possible dynamic re-configuration of ports. In case of port dynamic re-configuration some modules can logically "disappear" as a result of port split and un-spilt operations, which can cause missing of some modules, in case this info is taken from port to module mapping info.

2019-10-06Revert "libata, freezer: avoid block device removal while system is frozen"Mika Westerberg
This reverts commit 85fbd722ad0f5d64d1ad15888cd1eb2188bfb557. The commit was added as a quick band-aid for a hang that happened when a block device was removed during system suspend. Now that bdi_wq is not freezable anymore the hang should not be possible and we can get rid of this hack by reverting it. Acked-by: Rafael J.

2019-10-06net: dsa: b53: Do not clear existing mirrored port maskFlorian Fainelli
Clearing the existing bitmask of mirrored ports essentially prevents us from capturing more than one port at any given time. This is clearly wrong, do not clear the bitmask prior to setting up the new port.
