[PATCH OLK-5.10] KVM: arm64: Make ICC_*SGI*_EL1 undef in the absence of a vGICv3

From: Marc Zyngier <maz(a)kernel.org> stable inclusion from stable-v5.10.225 commit 15818af2f7aa55eff375333cb7689df15d3f24ef category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IAR5D2 CVE: CVE-2024-46707 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------------------------- commit 3e6245ebe7ef341639e9a7e402b3ade8ad45a19f upstream. On a system with a GICv3, if a guest hasn't been configured with GICv3 and that the host is not capable of GICv2 emulation, a write to any of the ICC_*SGI*_EL1 registers is trapped to EL2. We therefore try to emulate the SGI access, only to hit a NULL pointer as no private interrupt is allocated (no GIC, remember?). The obvious fix is to give the guest what it deserves, in the shape of a UNDEF exception.

From: Filipe Manana <fdmanana(a)suse.com> mainline inclusion from mainline-v6.11-rc1 commit 119474bdbac0858053cf367c8c932dd5c4bb4e85 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IARX0N Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- There are no callers of btrfs_lookup_extent_info() that pass a NULL value for the transaction handle argument, so there's no point in having special logic to deal with the NULL. The last caller that passed a NULL value was removed in commit 19b546d7a1b2 ("btrfs: relocation: Use btrfs_find_all_leafs to locate data extent parent tree leaves"). So remove the NULL handling from btrfs_lookup_extent_info().

Offering: HULK hulk inclusion category: bugfix bugzilla: https://codehub-y.huawei.com/hulk/bugzilla/issues/196 -------------------------------- There is following deadlock issue: CPU0 CPU1 ==== ==== kretprobe_trampoline kmem_cache_alloc trampoline_handler kmemleak_alloc __kretprobe_trampoline_handler create_object kretprobe_hash_lock <-- hold kmemleak lock <-- hold kretprobe table lock __link_object recycle_rp_inst stack_trace_save kfree_rcu kvfree_call_rcu ... kmemleak_ignore unwind_next_frame kretprobe_find_ret_addr <-- wait for kmemleak lock kretprobe_hash_lock <-- wait for kretprobe table lock One task on CPU0 hold kretprobe_hash_lock and wait for kmemleak_lock, however, kmemleak_lock was held by other task on CPU1 and that task is waiting for kretprobe_hash_lock, then deadlock happended. To fix it, move kfree_rcu() out of kretprobe table lock area.
