Some of these gotos are before the reinitializations of\nb_entry_name and buffer.  To maintain the invariant that b_entry_name and\nbuffer are NULL at the top of the loop, and thus acceptable arguments to\nkfree, these variables are now set to NULL after the kfrees.\n\nThis seems to be the simplest solution.

We use\ns_want_extra_isize and s_min_extra_isize to decide by how much we should\nexpand the inode. If EXT4_FEATURE_RO_COMPAT_EXTRA_ISIZE feature is set\nthen we expand the inode by max(s_want_extra_isize, s_min_extra_isize ,\nsizeof(ext4_inode) - EXT4_GOOD_OLD_INODE_SIZE) bytes. Actually it is\nstill an open question about whether users should be able to set\ns_*_extra_isize smaller than the known fields or not.\n\nThis patch also adds the functionality to expand inodes to include the\nnewly added fields. We start by trying to expand by s_want_extra_isize\nbytes and if its fails we try to expand by s_min_extra_isize bytes. This\nis done by changing the i_extra_isize if enough space is available in\nthe inode and no EAs are present. If EAs are present and there is enough\nspace in the inode then the EAs in the inode are shifted to make space.\nIf enough space is not available in the inode due to the EAs then 1 or\nmore EAs are shifted to the external EA block.

So\nthis patch also adds the EXT4_FEATURE_RO_COMPAT_EXTRA_ISIZE feature\nflag(ro-compat so that older kernels can\u0027t create inodes with a smaller\nextra_isize). which indicates if the fields fitting inside\ns_min_extra_isize are available or not.  If the expansion of inodes if\nunsuccessful then this feature will be disabled.  This feature is only\nenabled if requested by the sysadmin.\n\nNone of the extended inode fields is critical for correct filesystem\noperation.\n\nSigned-off-by: Andreas Dilger \u003cadilger@clusterfs.com\u003e\nSigned-off-by: Kalpak Shah \u003ckalpak@clusterfs.com\u003e\nSigned-off-by: Eric Sandeen \u003csandeen@redhat.com\u003e\nSigned-off-by: Dave Kleikamp \u003cshaggy@linux.vnet.ibm.com\u003e\nSigned-off-by: Mingming Cao \u003ccmm@us.ibm.com\u003e\nSigned-off-by: \"Theodore Ts\u0027o\" \u003ctytso@mit.edu\u003e\n\n"

      "message": "[PATCH] ext[34]: EA block reference count racing fix\n\nThere are race issues around ext[34] xattr block release code.\n\next[34]_xattr_release_block() checks the reference count of xattr block\n(h_refcount) and frees that xattr block if it is the last one reference it.\n Unlike ext2, the check of this counter is unprotected by any lock.\next[34]_xattr_release_block() will free the mb_cache entry before freeing\nthat xattr block.  There is a small window between the check for the re\nh_refcount \u003d\u003d1 and the call to mb_cache_entry_free().  During this small\nwindow another inode might find this xattr block from the mbcache and reuse\nit, racing a refcount updates.  The xattr block will later be freed by the\nfirst inode without notice other inode is still use it.  Later if that\nblock is reallocated as a datablock for other file, then more serious\nproblem might happen.\n\nWe need put a lock around places checking the refount as well to avoid\nracing issue.  Another place need this kind of protection is in\next3_xattr_block_set(), where it will modify the xattr block content in-\nthe-fly if the refcount is 1 (means it\u0027s the only inode reference it).\n\nThis will also fix another issue: the xattr block may not get freed at all\nif no lock is to protect the refcount check at the release time.  It is\npossible that the last two inodes could release the shared xattr block at\nthe same time.  But both of them think they are not the last one so only\ndecreased the h_refcount without freeing xattr block at all.\n\nWe need to call lock_buffer() after ext3_journal_get_write_access() to\navoid deadlock (because the later will call lock_buffer()/unlock_buffer\n() as well).\n\nSigned-off-by: Mingming Cao \u003ccmm@us.ibm.com\u003e\nCc: Andreas Gruenbacher \u003cagruen@suse.de\u003e\nCc: \u003clinux-ext4@vger.kernel.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n"
