二、漏洞分析结构反馈
 影响性分析说明：
  In the Linux kernel, the following vulnerability has been resolved:bpf: copy_verifier_state() should copy  loop_entry  fieldThe bpf_verifier_state.loop_entry state should be copied bycopy_verifier_state(). Otherwise, .loop_entry values from unrelatedstates would poison env->cur_state.Additionally, env->stack should not contain any states with.loop_entry != NULL. The states in env->stack are yet to be verified,while .loop_entry is set for states that reached an equivalent state.This means that env->cur_state->loop_entry should always be NULL afterpop_stack().See the selftest in the next commit for an example of the program thatis not safe yet is accepted by verifier w/o this fix.This change has some verification performance impact for selftests:File                                Program                       Insns (A)  Insns (B)  Insns   (DIFF)  States (A)  States (B)  States (DIFF)----------------------------------  ----------------------------  ---------  ---------  --------------  ----------  ----------  -------------arena_htab.bpf.o                    arena_htab_llvm                     717        426  -291 (-40.59%)          57          37  -20 (-35.09%)arena_htab_asm.bpf.o                arena_htab_asm                      597        445  -152 (-25.46%)          47          37  -10 (-21.28%)arena_list.bpf.o                    arena_list_del                      309        279    -30 (-9.71%)          23          14   -9 (-39.13%)iters.bpf.o                         iter_subprog_check_stacksafe        155        141    -14 (-9.03%)          15          14    -1 (-6.67%)iters.bpf.o                         iter_subprog_iters                 1094       1003    -91 (-8.32%)          88          83    -5 (-5.68%)iters.bpf.o                         loop_state_deps2                    479        725  +246 (+51.36%)          46          63  +17 (+36.96%)kmem_cache_iter.bpf.o               open_coded_iter                      63         59     -4 (-6.35%)           7           6   -1 (-14.29%)verifier_bits_iter.bpf.o            max_words                            92         84     -8 (-8.70%)           8           7   -1 (-12.50%)verifier_iterating_callbacks.bpf.o  cond_break2                         113        107     -6 (-5.31%)          12          12    +0 (+0.00%)And significant negative impact for sched_ext:File               Program                 Insns (A)  Insns (B)  Insns         (DIFF)  States (A)  States (B)  States      (DIFF)-----------------  ----------------------  ---------  ---------  --------------------  ----------  ----------  ------------------bpf.bpf.o          lavd_init                    7039      14723      +7684 (+109.16%)         490        1139     +649 (+132.45%)bpf.bpf.o          layered_dispatch            11485      10548         -937 (-8.16%)         848         762       -86 (-10.14%)bpf.bpf.o          layered_dump                 7422    1000001  +992579 (+13373.47%)         681       31178  +30497 (+4478.27%)bpf.bpf.o          layered_enqueue             16854      71127     +54273 (+322.02%)        1611        6450    +4839 (+300.37%)bpf.bpf.o          p2dq_dispatch                 665        791        +126 (+18.95%)          68          78       +10 (+14.71%)bpf.bpf.o          p2dq_init                    2343       2980        +637 (+27.19%)         201         237       +36 (+17.91%)bpf.bpf.o          refresh_layer_cpumasks      16487     674760   +658273 (+3992.68%)        1770       65370  +63600 (+3593.22%)bpf.bpf.o          rusty_select_cpu             1937      40872    +38935 (+2010.07%)         177        3210   +3033 (+1713.56%)scx_central.bpf.o  central_dispatch              636       2687      +2051 (+322.48%)          63         227     +164 (+260.32%)scx_nest.bpf.o     nest_init                     636        815        +179 (+28.14%)          60          73       +13 (+21.67%)scx_qmap.bpf.o     qmap_dispatch      ---truncated---
