I confirmed the solution, it worked. Also, I tried to submit the patch against the linux kernel (and/or Seccomp-BPF subtree) following the official kernel guide (https://www.kernel.org/doc/html/latest/process/submitting-patches.html) but I couldn't even find the 33554432 value by doing:
git clone git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git grep 33554432 -R linux Got this: linux/tools/power/x86/turbostat/turbostat.c:unsigned int irtl_time_units[] = { 1, 32, 1024, 32768, 1048576, 33554432, 0, 0 }; linux/drivers/idle/intel_idle.c: 1, 32, 1024, 32768, 1048576, 33554432, 0, 0 linux/drivers/pci/pcie/aspm.c: } else if (threshold_ns < 33554432) { linux/drivers/atm/idt77252_tables.h:/* 33554432.00 => 255 */ 0xff, /* => 352768.00 */ linux/drivers/atm/idt77252_tables.h:/* 335544320.00 => 255 */ 0xff, /* => 352768.00 */ linux/drivers/atm/idt77252_tables.h:/* 3355443200.00 => 255 */ 0xff, /* => 352768.00 */ linux/drivers/platform/x86/intel/pmc/core.c: * | 5 | 33554432 | linux/drivers/iio/frequency/adf4371.c:#define ADF4371_MODULUS1 33554432ULL linux/arch/arm/boot/dts/imx51-apf51.dts: clock-frequency = <33554432>; linux/arch/arm/kernel/insn.c: if (unlikely(offset < -33554432 || offset > 33554428)) { linux/mm/slab_common.c: INIT_KMALLOC_INFO(33554432, 32M) linux/sound/soc/codecs/rt1305.c: r0ohm = (rhl*10) / 33554432; linux/sound/soc/codecs/rt1305.c: r0ohm = (rhl*10) / 33554432; linux/sound/soc/codecs/twl4030.c: 8388608, 16777216, 33554432, 67108864}; None of which is an arm-specific constant for Seccomp-BPF. I tried. Once again, thank you for your help Paride Legovini, I would have never found this on my own. I gotta say, I'm very curious as to why this happens. What does the bpf_jit_limit value actually mean? I what what's BPF, I know what's JIT, I just don't know how they mix. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to libseccomp in Ubuntu. https://bugs.launchpad.net/bugs/1956954 Title: Can't load seccomp filter Status in libseccomp package in Ubuntu: Incomplete Bug description: After migrating from Ubuntu 20 amd64 to aarch64 I started experiencing "can't load seccomp filter" when doing `apt update && apt upgrade` and "Kernel refuses to turn on BPF filters" when using Puppeteer.
