btrfs_calc_trans_metadata_size() does an unsigned 32-bit multiplication, which can overflow if num_items >= 4 GB / (nodesize * BTRFS_MAX_LEVEL * 2). For a nodesize of 16kB, this overflow happens at 16k items. Usually, num_items is a small constant passed to btrfs_start_transaction(), but we also use btrfs_calc_trans_metadata_size() for metadata reservations for extent items in btrfs_delalloc_{reserve,release}_metadata(). In drop_outstanding_extents(), num_items is calculated as inode->reserved_extents - inode->outstanding_extents. The difference between these two counters is usually small, but if many delalloc extents are reserved and then the outstanding extents are merged in btrfs_merge_extent_hook(), the difference can become large enough to overflow in btrfs_calc_trans_metadata_size(). The overflow manifests itself as a leak of a multiple of 4 GB in delalloc_block_rsv and the metadata bytes_may_use counter. This in turn can cause early ENOSPC errors. Additionally, these WARN_ONs in extent-tree.c will be hit when unmounting: WARN_ON(fs_info->delalloc_block_rsv.size > 0); WARN_ON(fs_info->delalloc_block_rsv.reserved > 0); WARN_ON(space_info->bytes_pinned > 0 || space_info->bytes_reserved > 0 || space_info->bytes_may_use > 0); Fix it by casting nodesize to a u64 so that btrfs_calc_trans_metadata_size() does a full 64-bit multiplication. While we're here, do the same in btrfs_calc_trunc_metadata_size(); this can't overflow with any existing uses, but it's better to be safe here than have another hard-to-debug problem later on.

Before this, we use 'filled' mode here, ie. if all range has been filled with EXTENT_DEFRAG bits, get to clear it, but if the defrag range joins the adjacent delalloc range, then we'll have EXTENT_DEFRAG bits in extent_state until releasing this inode's pages, and that prevents extent_data from being freed. This clears the bit if any was found within the ordered extent. Signed-off-by:

Dmitry Torokhov authored
The 5th generation Thinkpad X1 Carbons use Synaptics touchpads accessible over SMBus/RMI, combined with ALPS or Elantech trackpoint devices instead of classic IBM/Lenovo trackpoints. Unfortunately there is no way for ALPS driver to detect whether it is dealing with touchpad + trackpoint combination or just a trackpoint, so we end up with a "phantom" dualpoint ALPS device in addition to real touchpad and trackpoint. Given that we do not have any special advanced handling for ALPS or Elantech trackpoints (unlike IBM trackpoints that have separate driver and a host of options) we are better off keeping the trackpoints in PS/2 emulation mode. We achieve that by setting serio type to SERIO_PS_PSTHRU, which will limit number of protocols psmouse driver will try. In addition to getting rid of the "phantom" touchpads, this will also speed up probing of F03 pass-through port. Reported-by:

In a kernel before above commit BGRT initializes late and uses ioremap() to map the image address. Ioremap validates the address, if it is not a valid physical address ioremap() just fails and returns. However in current kernel EFI BGRT initializes early and uses early_memremap() which does not validate the image address, and kernel panic happens. According to ACPI spec the BGRT image address should fall into EFI_BOOT_SERVICES_DATA, see the section 5.2.22.4 of below document: http://www.uefi.org/sites/default/files/resources/ACPI_6_1.pdf Fix this issue by validating the image address in efi_bgrt_init(). If the image address does not fall into any EFI_BOOT_SERVICES_DATA areas we just bail out with a warning message. Reported-by:

The commit e7ee4047 ("perf symbols: Fix symbols searching for module in buildid-cache") added the function to check kernel modules reside in the build-id cache. This was because there's no way to identify a DSO which is actually a kernel module. So it searched linkname of the file and find ".ko" suffix. But this does not work for compressed kernel modules and now such DSOs hCcave correct symtab_type now. So no need to check it anymore. This patch essentially reverts the commit. Signed-off-by:

The symsrc__init() overwrites dso->symtab_type as symsrc->type in dso__load_sym(). But for compressed kernel modules in the build-id cache, it should have original symtab type to be decompressed as needed. This fixes perf annotate to show disassembly of the function properly. Signed-off-by:

If a kernel modules is compressed, it should be decompressed before running objdump to parse binary data correctly. This fixes a failure of object code reading test for me. Signed-off-by:

The commit 6ebd2547 ("perf annotate: Fix a bug following symbolic link of a build-id file") changed to use dirname to follow the symlink. But it only considers new-style build-id cache names so old names fail on readlink() and force to use system path which might not available. Signed-off-by:

Pull printk fix from Petr Mladek: "This reverts a fix added into 4.12-rc1. It caused the kernel log to be printed on another console when two consoles of the same type were defined, e.g. console=ttyS0 console=ttyS1. This configuration was never supported by kernel itself, but it started to make sense with systemd. In other words, the commit broke userspace" * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/pmladek/printk: Revert "printk: fix double printing with earlycon"
