[PATCH] NFSv4: fix a mount deadlock in NFS v4.1 client

by Oleksandr Tymoshenko

nfs41_init_clientid does not signal a failure condition from nfs4_proc_exchange_id and nfs4_proc_create_session to a client which may lead to mount syscall indefinitely blocked in the following stack trace: nfs_wait_client_init_complete nfs41_discover_server_trunking nfs4_discover_server_trunking nfs4_init_client nfs4_set_client nfs4_create_server nfs4_try_get_tree vfs_get_tree do_new_mount __se_sys_mount and the client stuck in uninitialized state. In addition to this all subsequent mount calls would also get blocked in nfs_match_client waiting for the uninitialized client to finish initialization: nfs_wait_client_init_complete nfs_match_client nfs_get_client nfs4_set_client nfs4_create_server nfs4_try_get_tree vfs_get_tree do_new_mount __se_sys_mount To avoid this situation propagate error condition to the mount thread and let mount syscall fail properly.

[PATCH v3] KVM: arm64: Add memory length checks and remove inline in do_ffa_mem_xfer

by Snehal Koukuntla

When we share memory through FF-A and the description of the buffers exceeds the size of the mapped buffer, the fragmentation API is used. The fragmentation API allows specifying chunks of descriptors in subsequent FF-A fragment calls and no upper limit has been established for this. The entire memory region transferred is identified by a handle which can be used to reclaim the transferred memory. To be able to reclaim the memory, the description of the buffers has to fit in the ffa_desc_buf. Add a bounds check on the FF-A sharing path to prevent the memory reclaim from failing. Also do_ffa_mem_xfer() does not need __always_inline Fixes: 634d90cf0ac65 ("KVM: arm64: Handle FFA_MEM_LEND calls from the host") Cc: stable(a)vger.kernel.org Reviewed-by: Sebastian Ene <sebastianene(a)google.com> Signed-off-by: Snehal Koukuntla <snehalreddy(a)google.com> --- arch/arm64/kvm/hyp/nvhe/ffa.c | 7 ++++++- 1 file changed, 6 insertions(+), 1 deletion(-) diff --git a/arch/arm64/kvm/hyp/nvhe/ffa.c b/arch/arm64/kvm/hyp/nvhe/ffa.c index e715c157c2c4..637425f63fd1 100644 --- a/arch/arm64/kvm/hyp/nvhe/ffa.c +++ b/arch/arm64/kvm/hyp/nvhe/ffa.c @@ -426,7 +426,7 @@ static void do_ffa_mem_frag_tx(struct arm_smccc_res *res, return; } -static __always_inline void do_ffa_mem_xfer(const u64 func_id, +static void do_ffa_mem_xfer(const u64 func_id, struct arm_smccc_res *res, struct kvm_cpu_context *ctxt) { @@ -461,6 +461,11 @@ static __always_inline void do_ffa_mem_xfer(const u64 func_id, goto out_unlock; } + if (len > ffa_desc_buf.len) { + ret = FFA_RET_NO_MEMORY; + goto out_unlock; + } + buf = hyp_buffers.tx; memcpy(buf, host_buffers.tx, fraglen); -- 2.46.0.598.g6f2099f65c-goog

[PATCH 6.6] membarrier: riscv: Add full memory barrier in switch_mm()

by WangYuli

From: Andrea Parri <parri.andrea(a)gmail.com> [ Upstream commit d6cfd1770f20392d7009ae1fdb04733794514fa9 ] The membarrier system call requires a full memory barrier after storing to rq->curr, before going back to user-space. The barrier is only needed when switching between processes: the barrier is implied by mmdrop() when switching from kernel to userspace, and it's not needed when switching from userspace to kernel. Rely on the feature/mechanism ARCH_HAS_MEMBARRIER_CALLBACKS and on the primitive membarrier_arch_switch_mm(), already adopted by the PowerPC architecture, to insert the required barrier.

[PATCH RESEND] drm/sti: avoid potential dereference of error pointers in sti_gdp_atomic_check

The return value of drm_atomic_get_crtc_state() needs to be checked. To avoid use of error pointer 'crtc_state' in case of the failure.
