If this happens enough times, the counter will rollover and the reference freed, leading to a double free which can be used to do 'bad things'. In order to prevent this, move the point of possible failure above the point where the reference counter is incremented. Also save any meaningful return values to be applied to the return data at the appropriate point in time. This issue was caught with KASAN.

We also find that, cgroup_v1_psi_files is used only in kernel/cgroup/cgroup.c and kernel/sched/cpuacct.c. Therefore, move extern struct cftype cgroup_v1_psi_files to kernel/sched/cpuacct.c.This also solved the compile error, because, then CONFIG_CGROUP=n, CONFIG_CGROUP_CPUACCT=n, the kernel/sched/cpuacct.c is not compiled, which will solve the compile error.

In binder_transaction_buffer_release() the 'failed_at' offset indicates the number of objects to clean up. However, this function was changed by commit 44d8047f ("binder: use standard functions to allocate fds"), to release all the objects in the buffer when 'failed_at' is zero. This introduced an issue when a transaction buffer is released without any objects having been processed so far. In this case, 'failed_at' is indeed zero yet it is misinterpreted as releasing the entire buffer. This leads to use-after-free errors where nodes are incorrectly freed and subsequently accessed. Such is the case in the following KASAN report: ================================================================== BUG: KASAN: slab-use-after-free in binder_thread_read+0xc40/0x1f30 Read of size 8 at addr ffff4faf037cfc58 by task poc/474 CPU: 6 PID: 474 Comm: poc Not tainted 6.3.0-12570-g7df047b3 #5 Hardware name: linux,dummy-virt (DT) Call trace: dump_backtrace+0x94/0xec show_stack+0x18/0x24 dump_stack_lvl+0x48/0x60 print_report+0xf8/0x5b8 kasan_report+0xb8/0xfc __asan_load8+0x9c/0xb8 binder_thread_read+0xc40/0x1f30 binder_ioctl+0xd9c/0x1768 __arm64_sys_ioctl+0xd4/0x118 invoke_syscall+0x60/0x188 [...] Allocated by task 474: kasan_save_stack+0x3c/0x64 kasan_set_track+0x2c/0x40 kasan_save_alloc_info+0x24/0x34 __kasan_kmalloc+0xb8/0xbc kmalloc_trace+0x48/0x5c binder_new_node+0x3c/0x3a4 binder_transaction+0x2b58/0x36f0 binder_thread_write+0x8e0/0x1b78 binder_ioctl+0x14a0/0x1768 __arm64_sys_ioctl+0xd4/0x118 invoke_syscall+0x60/0x188 [...] Freed by task 475: kasan_save_stack+0x3c/0x64 kasan_set_track+0x2c/0x40 kasan_save_free_info+0x38/0x5c __kasan_slab_free+0xe8/0x154 __kmem_cache_free+0x128/0x2bc kfree+0x58/0x70 binder_dec_node_tmpref+0x178/0x1fc binder_transaction_buffer_release+0x430/0x628 binder_transaction+0x1954/0x36f0 binder_thread_write+0x8e0/0x1b78 binder_ioctl+0x14a0/0x1768 __arm64_sys_ioctl+0xd4/0x118 invoke_syscall+0x60/0x188 [...] ================================================================== In order to avoid these issues, let's always calculate the intended 'failed_at' offset beforehand.

On further discussion and consideration that check was probably too aggressive. Instead of returning -EINVAL, a better fix would be to just prevent the out of bounds read but continue the process. Background: The value of "pp->rxq_def" is a number between 0-7 by default, or even higher depending on the value of "rxq_number", which is a module parameter. If the value is more than the number of available CPUs then it will trigger the WARN() in cpu_max_bits_warn().

Currently the local 'node rw lock' is held during calling tipc_lxc_xmit() to protect the peer_net not being freed by another thread. However, when receiving these packets, tipc_node_add_conn() might be called where the peer 'node rw lock' is acquired. Then a dead lock warning is triggered by lockdep detector, although it is not a real dead lock: WARNING: possible recursive locking detected -------------------------------------------- conn_server/1086 is trying to acquire lock: ffff8880065cb020 (&n->lock#2){++--}-{2:2}, \ at: tipc_node_add_conn.cold.76+0xaa/0x211 [tipc] but task is already holding lock: ffff8880065cd020 (&n->lock#2){++--}-{2:2}, \ at: tipc_node_xmit+0x285/0xb30 [tipc] other info that might help us debug this: Possible unsafe locking scenario: CPU0 ---- lock(&n->lock#2); lock(&n->lock#2); *** DEADLOCK *** May be due to missing lock nesting notation 4 locks held by conn_server/1086: #0: ffff8880036d1e40 (sk_lock-AF_TIPC){+.+.}-{0:0}, \ at: tipc_accept+0x9c0/0x10b0 [tipc] #1: ffff8880036d5f80 (sk_lock-AF_TIPC/1){+.+.}-{0:0}, \ at: tipc_accept+0x363/0x10b0 [tipc] #2: ffff8880065cd020 (&n->lock#2){++--}-{2:2}, \ at: tipc_node_xmit+0x285/0xb30 [tipc] #3: ffff888012e13370 (slock-AF_TIPC){+...}-{2:2}, \ at: tipc_sk_rcv+0x2da/0x1b40 [tipc] Call Trace: <TASK> dump_stack_lvl+0x44/0x5b __lock_acquire.cold.77+0x1f2/0x3d7 lock_acquire+0x1d2/0x610 _raw_write_lock_bh+0x38/0x80 tipc_node_add_conn.cold.76+0xaa/0x211 [tipc] tipc_sk_finish_conn+0x21e/0x640 [tipc] tipc_sk_filter_rcv+0x147b/0x3030 [tipc] tipc_sk_rcv+0xbb4/0x1b40 [tipc] tipc_lxc_xmit+0x225/0x26b [tipc] tipc_node_xmit.cold.82+0x4a/0x102 [tipc] __tipc_sendstream+0x879/0xff0 [tipc] tipc_accept+0x966/0x10b0 [tipc] do_accept+0x37d/0x590 This patch avoids this warning by not holding the 'node rw lock' before calling tipc_lxc_xmit(). As to protect the 'peer_net', rcu_read_lock() should be enough, as in cleanup_net() when freeing the netns, it calls synchronize_rcu() before the free is continued. Also since tipc_lxc_xmit() is like the RX path in tipc_rcv(), it makes sense to call it under rcu_read_lock(). Note that the right lock order must be: rcu_read_lock(); tipc_node_read_lock(n); tipc_node_read_unlock(n); tipc_lxc_xmit(); rcu_read_unlock(); instead of: tipc_node_read_lock(n); rcu_read_lock(); tipc_node_read_unlock(n); tipc_lxc_xmit(); rcu_read_unlock(); and we have to call tipc_node_read_lock/unlock() twice in tipc_node_xmit().

This can lead to a route in the default VRF with a preferred source address not being flushed when the address is deleted. Consider the following example: # ip address add dev dummy1 192.0.2.1/28 # ip address add dev dummy1 192.0.2.17/28 # ip route add 198.51.100.0/24 via 192.0.2.2 src 192.0.2.17 metric 100 # ip route add table 0 198.51.100.0/24 via 192.0.2.2 src 192.0.2.17 metric 200 # ip route show 198.51.100.0/24 198.51.100.0/24 via 192.0.2.2 dev dummy1 src 192.0.2.17 metric 100 198.51.100.0/24 via 192.0.2.2 dev dummy1 src 192.0.2.17 metric 200 Both routes are installed in the default VRF, but they are using two different FIB info structures. One with a metric of 100 and table ID of 254 (main) and one with a metric of 200 and table ID of 0. Therefore, when the preferred source address is deleted from the default VRF, the second route is not flushed: # ip address del dev dummy1 192.0.2.17/28 # ip route show 198.51.100.0/24 198.51.100.0/24 via 192.0.2.2 dev dummy1 src 192.0.2.17 metric 200 Fix by storing a table ID of 254 instead of 0 in the route configuration structure. Add a test case that fails before the fix: # ./fib_tests.sh -t ipv4_del_addr IPv4 delete address route tests Regular FIB info TEST: Route removed from VRF when source address deleted [ OK ] TEST: Route in default VRF not removed [ OK ] TEST: Route removed in default VRF when source address deleted [ OK ] TEST: Route in VRF is not removed by address delete [ OK ] Identical FIB info with different table ID TEST: Route removed from VRF when source address deleted [ OK ] TEST: Route in default VRF not removed [ OK ] TEST: Route removed in default VRF when source address deleted [ OK ] TEST: Route in VRF is not removed by address delete [ OK ] Table ID 0 TEST: Route removed in default VRF when source address deleted [FAIL] Tests passed: 8 Tests failed: 1 And passes after: # ./fib_tests.sh -t ipv4_del_addr IPv4 delete address route tests Regular FIB info TEST: Route removed from VRF when source address deleted [ OK ] TEST: Route in default VRF not removed [ OK ] TEST: Route removed in default VRF when source address deleted [ OK ] TEST: Route in VRF is not removed by address delete [ OK ] Identical FIB info with different table ID TEST: Route removed from VRF when source address deleted [ OK ] TEST: Route in default VRF not removed [ OK ] TEST: Route removed in default VRF when source address deleted [ OK ] TEST: Route in VRF is not removed by address delete [ OK ] Table ID 0 TEST: Route removed in default VRF when source address deleted [ OK ] Tests passed: 9 Tests failed: 0 Fixes: 5a56a0b3 ("net: Don't delete routes in different VRFs") Reported-by: NDonald Sharp <sharpd@nvidia.com> Signed-off-by: NIdo Schimmel <idosch@nvidia.com> Reviewed-by: NDavid Ahern <dsahern@kernel.org> Signed-off-by: NJakub Kicinski <kuba@kernel.org> Signed-off-by: NSasha Levin <sashal@kernel.org> Signed-off-by: Nsanglipeng <sanglipeng1@jd.com> (cherry picked from commit dd2ab3c3)

The patch proposes to check for BUSY flag only when regmap_read() succeed. Compile test only. Found by Linux Verification Center (linuxtesting.org) with SVACE.
