2017-06-19btrfs: remove root usage from can_overcommitJeff Mahoney1-36/+46
can_overcommit using the root to determine the allocation profile is the only use of a root in the call graph below reserve_metadata_bytes. It turns out that we only need to know whether the allocation is for the chunk root or not -- and we can pass that around as a bool instead. This allows us to pull root usage out of the reservation path all the way up to reserve_metadata_bytes itself, which uses it only to compare against fs_info->chunk_root to set the bool. In turn, this eliminates a bunch of races where we use a particular root too early in the mount process.

2017-06-19btrfs: cleanup root usage by btrfs_get_alloc_profileJeff Mahoney5-15/+28
There are two places where we don't already know what kind of alloc profile we need before calling btrfs_get_alloc_profile, but we need access to a root everywhere we call it. This patch adds helpers for btrfs_{data,metadata,system}_alloc_profile() and relegates btrfs_system_alloc_profile to a static for use in those two cases. The next patch will eliminate one of those.

2017-06-19Btrfs: work around maybe-uninitialized warningArnd Bergmann1-2/+2
A rewrite of btrfs_submit_direct_hook appears to have introduced a warning: fs/btrfs/inode.c: In function 'btrfs_submit_direct_hook': fs/btrfs/inode.c:8467:14: error: 'bio' may be used uninitialized in this function [-Werror=maybe-uninitialized] Where the 'bio' variable was previously initialized unconditionally, it is now set in the "while (submit_len > 0)" loop that would never execute if submit_len is zero. Assuming this cannot happen in practice, we can avoid the warning by simply replacing the while{} loop with a do{}while() loop so the compiler knows that it will always be entered at least once.

2017-06-19Btrfs: change how we iterate bios in endioLiu Bo4-32/+37
Since dio submit has used bio_clone_fast, the submitted bio may not have a reliable bi_vcnt, for the bio vector iterations in checksum related functions, bio->bi_iter is not modified yet and it's safe to use bio_for_each_segment, while for those bio vector iterations in dio read's endio, we now save a copy of bvec_iter in struct btrfs_io_bio when cloning bios and use the helper __bio_for_each_segment with the saved bvec_iter to access each bvec. Also for dio reads which don't get split, we also need to save a copy of bio iterator in btrfs_bio_clone to let __bio_for_each_segments to access each bvec in dio read's endio. Note that it doesn't affect other calls of btrfs_bio_clone() because they don't need to use this iterator.

2017-06-19Btrfs: replace tree->mapping with tree->private_dataJosef Bacik9-91/+128
For extent_io tree's we have carried the address_mapping of the inode around in the io tree in order to pull the inode back out for calling into various tree ops hooks. This works fine when everything that has an extent_io_tree has an inode. But we are going to remove the btree_inode, so we need to change this. Instead just have a generic void * for private data that we can initialize with, and have all the tree ops use that instead. This had a lot of cascading changes but should be relatively straightforward.

This patch introduces the quota override flag to btrfs_fs_info, and a change to quota limit checking code to temporarily allow for quota to be overridden for processes with CAP_SYS_RESOURCE. It's useful for administrative programs, such as log rotation, that may need to temporarily use more disk space in order to free up a greater amount of overall disk space without yielding more disk space to the rest of userland. Eventually, we may want to add the idea of an operator-specific quota, operator reserved space, or something else to allow for administrative override, but this is perhaps the simplest solution.

2017-06-19mm: larger stack guard gap, between vmasHugh Dickins23-163/+152
Stack guard page is a useful feature to reduce a risk of stack smashing into a different mapping. We have been using a single page gap which is sufficient to prevent having stack adjacent to a different mapping. But this seems to be insufficient in the light of the stack usage in userspace. E.g. glibc uses as large as 64kB alloca() in many commonly used functions. Others use constructs liks gid_t buffer[NGROUPS_MAX] which is 256kB or stack strings with MAX_ARG_STRLEN. This will become especially dangerous for suid binaries and the default no limit for the stack size limit because those applications can be tricked to consume a large portion of the stack and a single glibc call could jump over the guard page. These attacks are not theoretical, unfortunatelly. Make those attacks less probable by increasing the stack guard gap to 1MB (on systems with 4k pages; but make it depend on the page size because systems with larger base pages might cap stack allocations in the PAGE_SIZE units) which should cover larger alloca() and VLA stack allocations. It is obviously not a full fix because the problem is somehow inherent, but it should reduce attack space a lot. One could argue that the gap size should be configurable from userspace, but that can be done later when somebody finds that the new 1MB is wrong for some special case applications. For now, add a kernel command line option (stack_guard_gap) to specify the stack gap size (in page units). Implementation wise, first delete all the old code for stack guard page: because although we could get away with accounting one extra page in a stack vma, accounting a larger gap can break userspace - case in point, a program run with "ulimit -S -v 20000" failed when the 1MB gap was counted for RLIMIT_AS; similar problems could come with RLIMIT_MLOCK and strict non-overcommit mode. Instead of keeping gap inside the stack vma, maintain the stack guard gap as a gap between vmas: using vm_start_gap() in place of vm_start (or vm_end_gap() in place of vm_end if VM_GROWSUP) in just those few places which need to respect the gap - mainly arch_get_unmapped_area(), and and the vma tree's subtree_gap support for that.

These ufs fixes are triggered by people actually caring now, not some sudden influx of new bugs. - Linus ] * 'ufs-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs: ufs_truncate_blocks(): fix the case when size is in the last direct block ufs: more deadlock prevention on tail unpacking ufs: avoid grabbing ->truncate_mutex if possible ufs_get_locked_page(): make sure we have buffer_heads ufs: fix s_size/s_dsize users ufs: fix reserved blocks check ufs: make ufs_freespace() return signed ufs: fix logics in "ufs: make fsck -f happy"
