[PATCH v3] ocfs2: fix kernel BUG in ocfs2_find_victim_chain

by Prithvi Tambewagh

syzbot reported a kernel BUG in ocfs2_find_victim_chain() because the `cl_next_free_rec` field of the allocation chain list (next free slot in the chain list) is 0, triggring the BUG_ON(!cl->cl_next_free_rec) condition in ocfs2_find_victim_chain() and panicking the kernel. To fix this, an if condition is introduced in ocfs2_claim_suballoc_bits(), just before calling ocfs2_find_victim_chain(), the code block in it being executed when either of the following conditions is true: 1. `cl_next_free_rec` is equal to 0, indicating that there are no free chains in the allocation chain list 2. `cl_next_free_rec` is greater than `cl_count` (the total number of chains in the allocation chain list) Either of them being true is indicative of the fact that there are no chains left for usage. This is addressed using ocfs2_error(), which prints the error log for debugging purposes, rather than panicking the kernel.

When the server has MPTCP enabled and the client also requests MPTCP, the sk passed to the BPF program is a subflow sk. Since subflows only handle partial data, replacing their sk_prot is meaningless and will cause traffic disruption. 2. When the server has MPTCP enabled but the client sends a TCP SYN without MPTCP, subflow_syn_recv_sock() performs a fallback on the subflow, replacing the subflow sk's sk_prot with the native sk_prot.

For the first case, we should prevent it from being combined with sockmap by setting sk_prot->psock_update_sk_prot to NULL, which will be blocked by sockmap's own flow. For the second case, since subflow_syn_recv_sock() has already restored sk_prot to native tcp_prot/tcpv6_prot, no further action is needed.

[PATCH v2] arm64: kernel: initialize missing kexec_buf->random field

Linux 6.17.10

by Greg Kroah-Hartman

I'm announcing the release of the 6.17.10 kernel. All users of the 6.17 kernel series must upgrade.

From: Hari Bathini <hbathini(a)linux.ibm.com> When KFENCE is enabled, total system memory is mapped at page level granularity. But in radix MMU mode, ~3GB additional memory is needed to map 100GB of system memory at page level granularity when compared to using 2MB direct mapping.This is not desired considering KFENCE is designed to be enabled in production kernels [1]. Mapping only the memory allocated for KFENCE pool at page granularity is sufficient to enable KFENCE support. So, allocate __kfence_pool during bootup and map it at page granularity instead of mapping all system memory at page granularity. Without patch: # cat /proc/meminfo MemTotal: 101201920 kB With patch: # cat /proc/meminfo MemTotal: 104483904 kB Note that enabling KFENCE at runtime is disabled for radix MMU for now, as it depends on the ability to split page table mappings and such APIs are not currently implemented for radix MMU. All kfence_test.c testcases passed with this patch.
