Re: panic in Linux emulation [was Re: 6.99.32: panic when starting X]

[Maxime Villard <max%M00nBSD.net@localhost>]

My mistake; committed great shit, sorry. However, the fix from njoly in
linux32/common/linux32_exec_elf32.c should be

        KASSERT(len <= LINUX32_ELF_AUX_ENTRIES * sizeof(Aux32Info));

instead of

        KASSERT(len <= LINUX32_ELF_AUX_ENTRIES * sizeof(AuxInfo));
