reiserfs: Fix memory leak in reiserfs_parse_options()

2020-10-29T09:12:19Z

[ Upstream commit e9d4709fcc26353df12070566970f080e651f0c9 ] When a usrjquota or grpjquota mount option is used multiple times, we will leak memory allocated for the file name. Make sure the last setting is used and all the previous ones are properly freed. Reported-by: syzbot+c9e294bbe0333a6b7640@syzkaller.appspotmail.com Signed-off-by: Jan Kara Signed-off-by: Sasha Levin

reiserfs: only call unlock_new_inode() if I_NEW

2020-10-29T09:12:16Z

[ Upstream commit 8859bf2b1278d064a139e3031451524a49a56bd0 ] unlock_new_inode() is only meant to be called after a new inode has already been inserted into the hash table. But reiserfs_new_inode() can call it even before it has inserted the inode, triggering the WARNING in unlock_new_inode(). Fix this by only calling unlock_new_inode() if the inode has the I_NEW flag set, indicating that it's in the table. This addresses the syzbot report "WARNING in unlock_new_inode" (https://syzkaller.appspot.com/bug?extid=187510916eb6a14598f7).

reiserfs: Fix oops during mount

2020-10-17T06:31:22Z

commit c2bb80b8bdd04dfe32364b78b61b6a47f717af52 upstream. With suitably crafted reiserfs image and mount command reiserfs will crash when trying to verify that XATTR_ROOT directory can be looked up in / as that recurses back to xattr code like: xattr_lookup+0x24/0x280 fs/reiserfs/xattr.c:395 reiserfs_xattr_get+0x89/0x540 fs/reiserfs/xattr.c:677 reiserfs_get_acl+0x63/0x690 fs/reiserfs/xattr_acl.c:209 get_acl+0x152/0x2e0 fs/posix_acl.c:141 check_acl fs/namei.c:277 [inline] acl_permission_check fs/namei.c:309 [inline] generic_permission+0x2ba/0x550 fs/namei.c:353 do_inode_permission fs/namei.c:398 [inline] inode_permission+0x234/0x4a0 fs/namei.c:463 lookup_one_len+0xa6/0x200 fs/namei.c:2557 reiserfs_lookup_privroot+0x85/0x1e0 fs/reiserfs/xattr.c:972 reiserfs_fill_super+0x2b51/0x3240 fs/reiserfs/super.c:2176 mount_bdev+0x24f/0x360 fs/super.c:1417 Fix the problem by bailing from reiserfs_xattr_get() when xattrs are not yet initialized.

reiserfs: Initialize inode keys properly

2020-10-17T06:31:22Z

commit 4443390e08d34d5771ab444f601cf71b3c9634a4 upstream. reiserfs_read_locked_inode() didn't initialize key length properly. Use _make_cpu_key() macro for key initialization so that all key member are properly initialized.
