Summary

In the Linux kernel, the following vulnerability has been resolved: ocfs2: fix crash when mount with quota enabled There is a reported crash when mounting ocfs2 with quota enabled. RIP: 0010:ocfs2_qinfo_lock_res_init+0x44/0x50 [ocfs2] Call Trace: ocfs2_local_read_info+0xb9/0x6f0 [ocfs2] dquot_load_quota_sb+0x216/0x470 dquot_load_quota_inode+0x85/0x100 ocfs2_enable_quotas+0xa0/0x1c0 [ocfs2] ocfs2_fill_super.cold+0xc8/0x1bf [ocfs2] mount_bdev+0x185/0x1b0 legacy_get_tree+0x27/0x40 vfs_get_tree+0x25/0xb0 path_mount+0x465/0xac0 __x64_sys_mount+0x103/0x140 It is caused by when initializing dqi_gqlock, the corresponding dqi_type and dqi_sb are not properly initialized. This issue is introduced by commit 6c85c2c72819, which wants to avoid accessing uninitialized variables in error cases. So make global quota info properly initialized.
