From: Duoming Zhou <duoming@zju.edu.cn> stable inclusion from stable-v6.1-rc1 commit 2568a7e0832ee30b0a351016d03062ab4e0e0a3f category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I5W7YH CVE: CVE-2022-3565 Reference: https://nvd.nist.gov/vuln/detail/CVE-2022-3565 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?i... -------------------------------- The l1oip_cleanup() traverses the l1oip_ilist and calls release_card() to cleanup module and stack. However, release_card() calls del_timer() to delete the timers such as keep_tl and timeout_tl. If the timer handler is running, the del_timer() will not stop it and result in UAF bugs. One of the processes is shown below: (cleanup routine) | (timer handler) release_card() | l1oip_timeout() ... | del_timer() | ... ... | kfree(hc) //FREE | | hc->timeout_on = 0 //USE Fix by calling del_timer_sync() in release_card(), which makes sure the timer handlers have finished before the resources, such as l1oip and so on, have been deallocated. What's more, the hc->workq and hc->socket_thread can kick those timers right back in. We add a bool flag to show if card is released. Then, check this flag in hc->workq and hc->socket_thread.

This gave us the required ordering between ->evict_inode() and sb->s_fs_info destruction. But the current implementation of binderfs_fill_super() has a memory leak in the rare circumstance that d_make_root() fails because ->put_super() is only called when sb->s_root is initialized. Fix this by removing ->put_super() and simply do all that work in binderfs_kill_super().

From: Maxim Mikityanskiy <maxtram95@gmail.com> maillist inclusion category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I5W7XW CVE: CVE-2022-3564 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/bluetooth/bluetooth-next.git... -------------------------------- Fix the race condition between the following two flows that run in parallel: 1. l2cap_reassemble_sdu -> chan->ops->recv (l2cap_sock_recv_cb) -> __sock_queue_rcv_skb. 2. bt_sock_recvmsg -> skb_recv_datagram, skb_free_datagram. An SKB can be queued by the first flow and immediately dequeued and freed by the second flow, therefore the callers of l2cap_reassemble_sdu can't use the SKB after that function returns. However, some places continue accessing struct l2cap_ctrl that resides in the SKB's CB for a short time after l2cap_reassemble_sdu returns, leading to a use-after-free condition (the stack trace is below, line numbers for kernel 5.19.8). Fix it by keeping a local copy of struct l2cap_ctrl.

If the beginning of the inode bitmap area is corrupted on disk, an inode with the same inode number as the root inode can be allocated and fail soon after. In this case, the subsequent call to nilfs_clear_inode() on that bogus root inode will wrongly decrement the reference counter of struct nilfs_root, and this will erroneously free struct nilfs_root, causing kernel oopses. This fixes the problem by changing nilfs_new_inode() to skip reserved inode numbers while repairing the inode bitmap.

From: Luoyouming <luoyouming@huawei.com> driver inclusion category: feature bugzilla: https://gitee.com/openeuler/kernel/issues/I5USIG ---------------------------------------------------------- The rq inline makes some changes as follows, Firstly, it is only used in user space. Secondly, it should notify hardware in QP RTR status. Thirdly, Add compatibility processing between different user space and kernel space. Change the HNS_ROCE_CAP_FLAG_RQ_INLINE to a new bit to prevent old kernel spaces / spaced from enabling rq inline.
