由 Herbert Xu 提交于
I have seen RX stalls on a machine that experienced a suspected OOM. After the stall, the RX buffer is empty on the guest side and there are exactly 16 entries available on the host side. As the number of entries is less than that required by a maximal skb, the host cannot proceed. The guest did not have a refill job scheduled. My diagnosis is that an OOM had occured, with the delayed refill job scheduled. The job was able to allocate at least one skb, but not enough to overcome the minimum required by the host to proceed. As the refill job would only reschedule itself if it failed completely to allocate any skbs, this would lead to an RX stall. The following patch removes this stall possibility by always rescheduling the refill job until the ring is totally refilled. Testing has shown that the RX stall no longer occurs whereas previously it would occur within a day.

The low-level MCDI code always uses 32-bit MMIO operations, and callers must pad input and output buffers to multiples of 4 bytes. The MCDI NVRAM functions are not doing this. Also, their buffers are declared as variable-length arrays with no explicit maximum length. Switch to a fixed buffer size based on the chunk size used by the MTD driver (which is a multiple of 4).

Due to a hardware bug in the SFC9000 family, the firmware must transfer raw GMAC statistics to host memory before aggregating them into the cooked (speed-independent) MAC statistics. Extend the stats buffer to support this. The length of the buffer is explicit in the MAC_STATS command, so this change is backward-compatible on both sides.

kvm_handle_sie_intercept uses a jump table to get the intercept handler for a SIE intercept. Static code analysis revealed a potential problem: the intercept_funcs jump table was defined to contain (0x48 >> 2) entries, but we only checked for code > 0x48 which would cause an off-by-one array overflow if code == 0x48. Use the compiler and ARRAY_SIZE to automatically set the limits.

Looks like repeatedly binding same fd to multiple gsi's with irqfd can use up a ton of kernel memory for irqfd structures. A simple fix is to allow each fd to only trigger one gsi: triggering a storm of interrupts in guest is likely useless anyway, and we can do it by binding a single gsi to many interrupts if we really want to.

When we queue an interrupt to the local apic, we set the IRR before the TMR. The vcpu can pick up the IRR and inject the interrupt before setting the TMR, and perhaps even EOI it, causing incorrect behaviour. The race is really insignificant since it can only occur on the first interrupt (usually following interrupts will not change TMR), but it's better closed than open. Fixed by reordering setting the TMR vs IRR. Cc: stable@kernel.org Signed-off-by: NAvi Kivity <avi@redhat.com> Signed-off-by: NMarcelo Tosatti <mtosatti@redhat.com>

GC is non-existent in netns, so after you hit GC threshold, no new dst entries will be created until someone triggers cleanup in init_net. Make xfrm4_dst_ops and xfrm6_dst_ops per-netns.
