## Description

In the Linux kernel, the following vulnerability has been resolved:  Revert "NFSD: Remove the cap on number of operations per NFSv4 COMPOUND"  I've found that pynfs COMP6 now leaves the connection or lease in a strange state, which causes CLOSE9 to hang indefinitely. I've dug into it a little, but I haven't been able to root-cause it yet. However, I bisected to commit 48aab1606fa8 ("NFSD: Remove the cap on number of operations per NFSv4 COMPOUND").  Tianshuo Han also reports a potential vulnerability when decoding an NFSv4 COMPOUND. An attacker can place an arbitrarily large op count in the COMPOUND header, which results in:  [   51.410584] nfsd: vmalloc error: size 1209533382144, exceeds total pages, mode:0xdc0(GFP_KERNEL|__GFP_ZERO), nodemask=(null),cpuset=/,mems_allowed=0  when NFSD attempts to allocate the COMPOUND op array.  Let's restore the operation-per-COMPOUND limit, but increased to 200 for now.
