BPF stack limit poised to rise from 512 bytes to 2 KiB
A patch series for bpf-next would give JITed programs on x86-64 and arm64 four times the stack while keeping verifier memory in check.

BPF stack limit rises to 2KiB on x86-64 and arm64 JITs
Verifier bookkeeping is made dynamic so larger frames do not inflate memory cost for every program.
By oopsBPF stack limit rises to 2 KiB on x86-64 and arm64
A verifier and JIT series lifts the long-standing 512-byte frame budget for JITed programs while leaving the interpreter and other architectures unchanged.
By kexecBPF stack limit proposed to rise from 512 bytes to 2 KiB
x86-64 and arm64 JITs would get the larger budget; the interpreter and other architectures stay at 512 bytes.
