ksock_lsm.c test was introduced as a part of a series [1]. This series landed on Sat Aug 15 2026. As it turns out, the test breaks on the CI when compiled by gcc [2]. Here is exact verification failure: 0: R1=ctx() R10=fp0 ; @ ksock_lsm.c:25185 0: (81) r6 = *(s32 *)(r1 +24) ; R1=ctx() R6=scalar(smin=0xffffffff80000000,smax=0x7fffffff) ; @ ksock_lsm.c:55 1: (85) call bpf_get_current_pid_tgid#14 ; R0=scalar() ; @ ksock_lsm.c:57 2: (55) if r6 != 0x0 goto pc+5 8: R6=scalar(smin=0xffffffff80000000,smax=0x7fffffff) R10=fp0 ; @ ksock_lsm.c:51 8: (bf) r0 = r6 ; R0=scalar(id=4,smin=0xffffffff80000000,smax=0x7fffffff) R6=scalar(id=4,smin=0xffffffff80000000,smax=0x7fffffff) 9: (95) exit Kumar Kartikeya Dwivedi figured out the error is in interaction of lsm context processing in reg->type == PTR_TO_CTX branch of check_mem_access() (which set's the range for 'ret' variable), and further coerce_reg_to_size_sx(). Disable the test on the CI for bpf-gcc for now to unblock the pipelines.

ksock_lsm.c test was introduced as a part of a series [1]. This series landed on Sat Aug 15 2026.
As it turns out, the test breaks on the CI when compiled by gcc [2].
Here is exact verification failure:
0: R1=ctx() R10=fp0
; @ ksock_lsm.c:25185
0: (81) r6 = *(s32 *)(r1 +24) ; R1=ctx() R6=scalar(smin=0xffffffff80000000,smax=0x7fffffff)
; @ ksock_lsm.c:55
1: (85) call bpf_get_current_pid_tgid#14 ; R0=scalar()
; @ ksock_lsm.c:57
2: (55) if r6 != 0x0 goto pc+5 8: R6=scalar(smin=0xffffffff80000000,smax=0x7fffffff) R10=fp0
; @ ksock_lsm.c:51
8: (bf) r0 = r6 ; R0=scalar(id=4,smin=0xffffffff80000000,smax=0x7fffffff) R6=scalar(id=4,smin=0xffffffff80000000,smax=0x7fffffff)
9: (95) exit
Kumar Kartikeya Dwivedi figured out the error is in interaction of lsm context processing in reg->type == PTR_TO_CTX branch of check_mem_access() (which set's the range for 'ret' variable), and further coerce_reg_to_size_sx().
Disable the test on the CI for bpf-gcc for now to unblock the pipelines.
