hfsplus: fix "unused node is not erased" error

2014-06-06T23:08:10+00:00

Zero newly allocated extents in the catalog tree if volume attributes tell us to. Not doing so we risk getting the "unused node is not erased" error. See kHFSUnusedNodeFix flag in Apple's source code for reference. There was a previous commit clearing the node when it is freed: commit 899bed05e9f6 ("hfsplus: fix issue with unzeroed unused b-tree nodes"). But it did not handle newly allocated extents (this patch fixes it). And it zeroed nodes in all trees unconditionally which is an overkill. This patch adds a condition and also switches to 'tree->node_size' as a simpler method of getting the length to zero.

hfsplus: add HFSX subfolder count support

2014-03-11T00:26:21+00:00

Adds support for HFSX 'HasFolderCount' flag and a corresponding 'folderCount' field in folder records. (For reference see HFS_FOLDERCOUNT and kHFSHasFolderCountBit/kHFSHasFolderCountMask in Apple's source code.) Ignoring subfolder count leads to fs errors found by Mac: ... Checking catalog hierarchy. HasFolderCount flag needs to be set (id = 105) (It should be 0x10 instead of 0) Incorrect folder count in a directory (id = 2) (It should be 7 instead of 6) ... Steps to reproduce: Format with "newfs_hfs -s /dev/diskXXX". Mount in Linux. Create a new directory in root. Unmount. Run "fsck_hfs /dev/diskXXX". The patch handles directory creation, deletion, and rename.

hfsplus: handle more on-disk corruptions without oopsing

2010-10-14T13:53:48+00:00

hfs seems prone to bad things when it encounters on disk corruption. Many values are read from disk, and used as lengths to memcpy, as an example. This patch fixes up several of these problematic cases. o sanity check the on-disk maximum key lengths on mount (these are set to a defined value at mkfs time and shouldn't differ) o check on-disk node keylens against the maximum key length for each tree o fix hfs_btree_open so that going out via free_tree: doesn't wind up in hfs_releasepage, which wants to follow the very pointer we were trying to set up: HFS_SB(sb)->cat_tree = hfs_btree_open() . failure gets to hfs_releasepage and tries to follow HFS_SB(sb)->cat_tree Tested with the fsfuzzer; it survives more than it used to.

[PATCH] extend the set of "attribute" shortcut macros

2007-02-11T18:51:35+00:00

Extend the set of "__attribute__" shortcut macros, and remove identical (and now superfluous) definitions from a couple of source files. based on a page at robert love's blog: http://rlove.org/log/2005102601 extend the set of shortcut macros defined in compiler-gcc.h with the following: #define __packed __attribute__((packed)) #define __weak __attribute__((weak)) #define __naked __attribute__((naked)) #define __noreturn __attribute__((noreturn)) #define __pure __attribute__((pure)) #define __aligned(x) __attribute__((aligned(x))) #define __printf(a,b) __attribute__((format(printf,a,b))) Once these are in place, it's up to subsystem maintainers to decide if they want to take advantage of them. there is already a strong precedent for using shortcuts like this in the source tree. The ones that might give people pause are "__aligned" and "__printf", but shortcuts for both of those are already in use, and in some ways very confusingly. note the two very different definitions for a macro named "ALIGNED": drivers/net/sgiseeq.c:#define ALIGNED(x) ((((unsigned long)(x)) + 0xf) & ~(0xf)) drivers/scsi/ultrastor.c:#define ALIGNED(x) __attribute__((aligned(x))) also: include/acpi/platform/acgcc.h: #define ACPI_PRINTF_LIKE(c) __attribute__ ((__format__ (__printf__, c, c+1))) Given the precedent, then, it seems logical to at least standardize on a consistent set of these macros.
