[PATCH OLK-5.10] tcp: add sanity checks to rx zerocopy
by Zhengchao Shao 30 Jan '24

30 Jan '24

From: Eric Dumazet <edumazet(a)google.com> maillist inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I8ZTOK Reference: https://lore.kernel.org/all/20240125103317.2334989-1-edumazet@google.com/ -------------------------------- TCP rx zerocopy intent is to map pages initially allocated from NIC drivers, not pages owned by a fs. This patch adds to can_map_frag() these additional checks: - Page must not be a compound one. - page->mapping must be NULL. This fixes the panic reported by ZhangPeng. syzbot was able to loopback packets built with sendfile(), mapping pages owned by an ext4 file to TCP rx zerocopy. r3 = socket$inet_tcp(0x2, 0x1, 0x0) mmap(&(0x7f0000ff9000/0x4000)=nil, 0x4000, 0x0, 0x12, r3, 0x0) r4 = socket$inet_tcp(0x2, 0x1, 0x0) bind$inet(r4, &(0x7f0000000000)={0x2, 0x4e24, @multicast1}, 0x10) connect$inet(r4, &(0x7f00000006c0)={0x2, 0x4e24, @empty}, 0x10) r5 = openat$dir(0xffffffffffffff9c, &(0x7f00000000c0)='./file0\x00', 0x181e42, 0x0) fallocate(r5, 0x0, 0x0, 0x85b8) sendfile(r4, r5, 0x0, 0x8ba0) getsockopt$inet_tcp_TCP_ZEROCOPY_RECEIVE(r4, 0x6, 0x23, &(0x7f00000001c0)={&(0x7f0000ffb000/0x3000)=nil, 0x3000, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0}, &(0x7f0000000440)=0x40) r6 = openat$dir(0xffffffffffffff9c, &(0x7f00000000c0)='./file0\x00', 0x181e42, 0x0) Fixes: 93ab6cc69162 ("tcp: implement mmap() for zero copy receive") Link: https://lore.kernel.org/netdev/5106a58e-04da-372a-b836-9d3d0bd2507b@huawei.… Reported-and-bisected-by: ZhangPeng <zhangpeng362(a)huawei.com> Signed-off-by: Eric Dumazet <edumazet(a)google.com> Cc: Arjun Roy <arjunroy(a)google.com> Cc: Matthew Wilcox <willy(a)infradead.org> Cc: linux-mm(a)vger.kernel.org Cc: Andrew Morton <akpm(a)linux-foundation.org> Cc: linux-fsdevel(a)vger.kernel.org Conflicts: net/ipv4/tcp.c Signed-off-by: Zhengchao Shao <shaozhengchao(a)huawei.com> --- net/ipv4/tcp.c | 9 +++++++-- 1 file changed, 7 insertions(+), 2 deletions(-) diff --git a/net/ipv4/tcp.c b/net/ipv4/tcp.c index dcbc5ec00da8..bb74fc0aa2d2 100644 --- a/net/ipv4/tcp.c +++ b/net/ipv4/tcp.c @@ -1917,6 +1917,8 @@ static int tcp_zerocopy_receive(struct sock *sk, ret = 0; curr_addr = address; while (length + PAGE_SIZE <= zc->length) { + struct page *page; + if (zc->recv_skip_hint < PAGE_SIZE) { u32 offset_frag; @@ -1944,7 +1946,10 @@ static int tcp_zerocopy_receive(struct sock *sk, if (!frags || offset_frag) break; } - if (skb_frag_size(frags) != PAGE_SIZE || skb_frag_off(frags)) { + + page = skb_frag_page(frags); + if (skb_frag_size(frags) != PAGE_SIZE || skb_frag_off(frags) || + PageCompound(page) || page->mapping) { int remaining = zc->recv_skip_hint; while (remaining && (skb_frag_size(frags) != PAGE_SIZE || @@ -1955,7 +1960,7 @@ static int tcp_zerocopy_receive(struct sock *sk, zc->recv_skip_hint -= remaining; break; } - pages[pg_idx] = skb_frag_page(frags); + pages[pg_idx] = page; pg_idx++; length += PAGE_SIZE; zc->recv_skip_hint -= PAGE_SIZE; -- 2.34.1

[PATCH openEuler-22.03-LTS-SP2] drm/atomic: Fix potential use-after-free in nonblocking commits
by Guo Mengqi 30 Jan '24

30 Jan '24

From: Daniel Vetter <daniel.vetter(a)ffwll.ch> stable inclusion from stable-v5.10.188 commit f09c0ac142c59495262dd80545f261b2aeeba538 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I7V6NJ CVE: CVE-2023-51043 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit 4e076c73e4f6e90816b30fcd4a0d7ab365087255 upstream. This requires a bit of background. Properly done a modeset driver's unload/remove sequence should be drm_dev_unplug(); drm_atomic_helper_shutdown(); drm_dev_put(); The trouble is that the drm_dev_unplugged() checks are by design racy, they do not synchronize against all outstanding ioctl. This is because those ioctl could block forever (both for modeset and for driver specific ioctls), leading to deadlocks in hotunplug. Instead the code sections that touch the hardware need to be annotated with drm_dev_enter/exit, to avoid accessing hardware resources after the unload/remove has finished. To avoid use-after-free issues all the involved userspace visible objects are supposed to hold a reference on the underlying drm_device, like drm_file does. The issue now is that we missed one, the atomic modeset ioctl can be run in a nonblocking fashion, and in that case it cannot rely on the implied drm_device reference provided by the ioctl calling context. This can result in a use-after-free if an nonblocking atomic commit is carefully raced against a driver unload. Fix this by unconditionally grabbing a drm_device reference for any drm_atomic_state structures. Strictly speaking this isn't required for blocking commits and TEST_ONLY calls, but it's the simpler approach. Thanks to shanzhulig for the initial idea of grabbing an unconditional reference, I just added comments, a condensed commit message and fixed a minor potential issue in where exactly we drop the final reference.

From: Daniel Vetter <daniel.vetter(a)ffwll.ch> stable inclusion from stable-v5.10.188 commit f09c0ac142c59495262dd80545f261b2aeeba538 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I7V6NJ CVE: CVE-2023-51043 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit 4e076c73e4f6e90816b30fcd4a0d7ab365087255 upstream. This requires a bit of background. Properly done a modeset driver's unload/remove sequence should be drm_dev_unplug(); drm_atomic_helper_shutdown(); drm_dev_put(); The trouble is that the drm_dev_unplugged() checks are by design racy, they do not synchronize against all outstanding ioctl. This is because those ioctl could block forever (both for modeset and for driver specific ioctls), leading to deadlocks in hotunplug. Instead the code sections that touch the hardware need to be annotated with drm_dev_enter/exit, to avoid accessing hardware resources after the unload/remove has finished. To avoid use-after-free issues all the involved userspace visible objects are supposed to hold a reference on the underlying drm_device, like drm_file does. The issue now is that we missed one, the atomic modeset ioctl can be run in a nonblocking fashion, and in that case it cannot rely on the implied drm_device reference provided by the ioctl calling context. This can result in a use-after-free if an nonblocking atomic commit is carefully raced against a driver unload. Fix this by unconditionally grabbing a drm_device reference for any drm_atomic_state structures. Strictly speaking this isn't required for blocking commits and TEST_ONLY calls, but it's the simpler approach. Thanks to shanzhulig for the initial idea of grabbing an unconditional reference, I just added comments, a condensed commit message and fixed a minor potential issue in where exactly we drop the final reference.

[PATCH openEuler-1.0-LTS] drm/atomic: Fix potential use-after-free in nonblocking commits
by Guo Mengqi 29 Jan '24

29 Jan '24

From: Daniel Vetter <daniel.vetter(a)ffwll.ch> stable inclusion from stable-v4.19.291 commit 73a82b22963defa87204f0f9f44a534adf7f831a category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I7V6NJ CVE: CVE-2023-51043 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit 4e076c73e4f6e90816b30fcd4a0d7ab365087255 upstream. This requires a bit of background. Properly done a modeset driver's unload/remove sequence should be drm_dev_unplug(); drm_atomic_helper_shutdown(); drm_dev_put(); The trouble is that the drm_dev_unplugged() checks are by design racy, they do not synchronize against all outstanding ioctl. This is because those ioctl could block forever (both for modeset and for driver specific ioctls), leading to deadlocks in hotunplug. Instead the code sections that touch the hardware need to be annotated with drm_dev_enter/exit, to avoid accessing hardware resources after the unload/remove has finished. To avoid use-after-free issues all the involved userspace visible objects are supposed to hold a reference on the underlying drm_device, like drm_file does. The issue now is that we missed one, the atomic modeset ioctl can be run in a nonblocking fashion, and in that case it cannot rely on the implied drm_device reference provided by the ioctl calling context. This can result in a use-after-free if an nonblocking atomic commit is carefully raced against a driver unload. Fix this by unconditionally grabbing a drm_device reference for any drm_atomic_state structures. Strictly speaking this isn't required for blocking commits and TEST_ONLY calls, but it's the simpler approach. Thanks to shanzhulig for the initial idea of grabbing an unconditional reference, I just added comments, a condensed commit message and fixed a minor potential issue in where exactly we drop the final reference.

[PATCH OLK-5.10] net/rds: Fix UBSAN: array-index-out-of-bounds in rds_cmsg_recv
by Dong Chenchen 29 Jan '24

29 Jan '24

From: Sharath Srinivasan <sharath.srinivasan(a)oracle.com> mainline inclusion from mainline-v6.7 commit 13e788deb7348cc88df34bed736c3b3b9927ea52 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I8YC9I CVE: CVE-2024-23849 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- Syzcaller UBSAN crash occurs in rds_cmsg_recv(), which reads inc->i_rx_lat_trace[j + 1] with index 4 (3 + 1), but with array size of 4 (RDS_RX_MAX_TRACES).

By comparing the packets from a normal connection and disconnection process with the testcase that triggered a KASAN report. We analyzed the cause of this bug as follows: 1. In the packets captured during a normal connection, the host sends a `Read Encryption Key Size` type of `HCI_CMD` packet (Command Opcode: 0x1408) to the controller to inquire the length of encryption key.After receiving this packet, the controller immediately replies with a Command Completepacket (Event Code: 0x0e) to return the Encryption Key Size. 2. In our fuzz test case, the timing of the controller's response to this packet was delayed to an unexpected point: after the RFCOMM and L2CAP layers had disconnected but before the HCI layer had disconnected. 3. After receiving the Encryption Key Size Response at the time described in point 2, the host still called the rfcomm_check_security function. However, by this time `struct l2cap_conn *conn = l2cap_pi(sk)->chan->conn;` had already been released, and when the function executed `return hci_conn_security(conn->hcon, d->sec_level, auth_type, d->out);`, specifically when accessing `conn->hcon`, a null-ptr-deref error occurred.
