The driver exposes EFI runtime services to user-space through an IOCTL interface, calling the EFI services function pointers directly without using the efivar API. Disallow access to the /dev/efi_test character device when the kernel is locked down to prevent arbitrary user-space to call EFI runtime services. Also require CAP_SYS_ADMIN to open the chardev to prevent unprivileged users to call the EFI runtime services, instead of just relying on the chardev file mode bits for this. The main user of this driver is the fwts [0] tool that already checks if the effective user ID is 0 and fails otherwise. So this change shouldn't cause any regression to this tool.

Currently, kernel fails to boot on some HyperV VMs when using EFI. And it's a potential issue on all x86 platforms. It's caused by broken kernel relocation on EFI systems, when below three conditions are met: 1. Kernel image is not loaded to the default address (LOAD_PHYSICAL_ADDR) by the loader. 2. There isn't enough room to contain the kernel, starting from the default load address (eg. something else occupied part the region). 3. In the memmap provided by EFI firmware, there is a memory region starts below LOAD_PHYSICAL_ADDR, and suitable for containing the kernel. EFI stub will perform a kernel relocation when condition 1 is met. But due to condition 2, EFI stub can't relocate kernel to the preferred address, so it fallback to ask EFI firmware to alloc lowest usable memory region, got the low region mentioned in condition 3, and relocated kernel there. It's incorrect to relocate the kernel below LOAD_PHYSICAL_ADDR. This is the lowest acceptable kernel relocation address. The first thing goes wrong is in arch/x86/boot/compressed/head_64.S. Kernel decompression will force use LOAD_PHYSICAL_ADDR as the output address if kernel is located below it. Then the relocation before decompression, which move kernel to the end of the decompression buffer, will overwrite other memory region, as there is no enough memory there. To fix it, just don't let EFI stub relocate the kernel to any address lower than lowest acceptable address. [ ardb: introduce efi_low_alloc_above() to reduce the scope of the change ] Signed-off-by:

The EFI stubloader for ARM starts out by allocating a 32 MB window at the base of RAM, in order to ensure that the decompressor (which blindly copies the uncompressed kernel into that window) does not overwrite other allocations that are made while running in the context of the EFI firmware. In some cases, (e.g., U-Boot running on the Raspberry Pi 2), this is causing boot failures because this initial allocation conflicts with a page of reserved memory at the base of RAM that contains the SMP spin tables and other pieces of firmware data and which was put there by the bootloader under the assumption that the TEXT_OFFSET window right below the kernel is only used partially during early boot, and will be left alone once the memory reservations are processed and taken into account. So let's permit reserved memory regions to exist in the region starting at the base of RAM, and ending at TEXT_OFFSET - 5 * PAGE_SIZE, which is the window below the kernel that is not touched by the early boot code.

Commit 428826f5 ("fdt: add support for rng-seed") introduced add_bootloader_randomness(), permitting randomness provided by the bootloader or firmware to be credited as entropy. However, the fact that the UEFI support code was already wired into the RNG subsystem via a call to add_device_randomness() was overlooked, and so it was not converted at the same time. Note that this UEFI (v2.4 or newer) feature is currently only implemented for EFI stub booting on ARM, and further note that CONFIG_RANDOM_TRUST_BOOTLOADER must be enabled, and this should be done only if there indeed is sufficient trust in the bootloader _and_ its source of randomness.

-
Andrew Price authored
When gfs2 was converted to use fs_context, the initialisation of the mount args structure to the currently active args was lost with the removal of gfs2_remount_fs(), so the checks of the new args on remount became checks against the default values instead of the current ones. This caused unexpected remount behaviour and test failures (xfstests generic/294, generic/306 and generic/452). Reinstate the args initialisation, this time in gfs2_init_fs_context() and conditional upon fc->purpose, as that's the only time we get control before the mount args are parsed in the remount process.

When VIRTIO_F_RING_EVENT_IDX is negotiated, virtio devices can use virtqueue_enable_cb_delayed_packed to reduce the number of device interrupts. At the moment, this is the case for virtio-net when the napi_tx module parameter is set to false. In this case, the virtio driver selects an event offset and expects that the device will send a notification when rolling over the event offset in the ring. However, if this roll-over happens before the event suppression structure update, the notification won't be sent. To address this race condition the driver needs to check wether the device rolled over the offset after updating the event suppression structure. With VIRTIO_F_RING_PACKED, the virtio driver did this by reading the flags field of the descriptor at the specified offset. Unfortunately, checking at the event offset isn't reliable: if descriptors are chained (e.g. when INDIRECT is off) not all descriptors are overwritten by the device, so it's possible that the device skipped the specific descriptor driver is checking when writing out used descriptors. If this happens, the driver won't detect the race condition and will incorrectly expect the device to send a notification. For virtio-net, the result will be a TX queue stall, with the transmission getting blocked forever. With the packed ring, it isn't easy to find a location which is guaranteed to change upon the roll-over, except the next device descriptor, as described in the spec: Writes of device and driver descriptors can generally be reordered, but each side (driver and device) are only required to poll (or test) a single location in memory: the next device descriptor after the one they processed previously, in circular order. while this might be sub-optimal, let's do exactly this for now.

Pull block and io_uring fixes from Jens Axboe: "A bit bigger than usual at this point in time, mostly due to some good bug hunting work by Pavel that resulted in three io_uring fixes from him and two from me. Anyway, this pull request contains: - Revert of the submit-and-wait optimization for io_uring, it can't always be done safely. It depends on commands always making progress on their own, which isn't necessarily the case outside of strict file IO. (me) - Series of two patches from me and three from Pavel, fixing issues with shared data and sequencing for io_uring. - Lastly, two timeout sequence fixes for io_uring (zhangyi) - Two nbd patches fixing races (Josef) - libahci regulator_get_optional() fix (Mark)" * tag 'for-linus-2019-10-26' of git://git.kernel.dk/linux-block: nbd: verify socket is supported during setup ata: libahci_platform: Fix regulator_get_optional() misuse nbd: handle racing with error'ed out commands nbd: protect cmd->status with cmd->lock io_uring: fix bad inflight accounting for SETUP_IOPOLL|SETUP_SQTHREAD io_uring: used cached copies of sq->dropped and cq->overflow io_uring: Fix race for sqes with userspace io_uring: Fix broken links with offloading io_uring: Fix corrupted user_data io_uring: correct timeout req sequence when inserting a new entry io_uring : correct timeout req sequence when waiting timeout io_uring: revert "io_uring: optimize submit_and_wait API" -

If we always compile the get_break_insn_length inline function we can remove the ifdefs and let dead code elimination take care of the warn branch that is now unreadable because the report_bug stub always returns BUG_TRAP_TYPE_BUG. Signed-off-by:
