[PATCH v2] runtest: Skip mremap06 in purecap

by Kevin Brodsky

The mremap06 test relies on being able to move a mapping into the unmapped space of an existing reservation (second call to mremap() in do_test()). This is explicitly disallowed in PCuABI (for all syscalls that can create mappings), and it is unclear if the original bug can be reproduced if remapping to another adddress, so let's just skip the test when running in purecap, at least for now.

[PATCH 00/10] Fixes to support reservations / PCuABI mmap*

by Kevin Brodsky

Hi, This series fixes various issues in LTP that prevent tests from passing when reservations / PCuABI address space management are implemented. Patch 1-3 are generic, and arguably general improvements. The remainder of the patches are PCuABI-specific, with appropriate #ifdef'ing where necessary. The changes are meant to be backwards-compatible (e.g. ERESERVATION is not assumed to be returned in PCuABI). Review branch: https://git.morello-project.org/kbrodsky-arm/morello-linux-ltp/-/commits/mo… Thanks, Kevin Kevin Brodsky (10): syscalls/munlock: Pass an appropriate length to munlock() syscalls/m{,un}lock: Use mmap() to obtain an owning pointer syscalls/m{,un}map: Pass a raw address when reusing an address range syscalls: Use PROT_MAX() where needed syscalls/mmap: Allow MREMAP_MAYMOVE in PCuABI syscalls/mlock{,2}: Expect ERESERVATION on unmapped area syscalls/mmap: Expect EINVAL on MAP_FIXED_NOREPLACE syscalls/mprotect: Expect EINVAL on null pointer syscalls/mremap: Expect EINVAL on narrow pointer syscalls/mmap: Skip MAP_GROWSDOWN tests in PCuABI .../syscalls/memfd_create/memfd_create_common.c | 3 ++- testcases/kernel/syscalls/mlock/mlock01.c | 13 +++---------- testcases/kernel/syscalls/mlock/mlock02.c | 12 +++++++++++- testcases/kernel/syscalls/mlock2/mlock202.c | 5 +++-- testcases/kernel/syscalls/mmap/mmap16.c | 11 +++++++++-- testcases/kernel/syscalls/mmap/mmap17.c | 4 ++++ testcases/kernel/syscalls/mmap/mmap18.c | 7 +++++++ testcases/kernel/syscalls/mmap/mmap19.c | 4 ++-- testcases/kernel/syscalls/mprotect/mprotect01.c | 11 +++++++++-- testcases/kernel/syscalls/mprotect/mprotect02.c | 3 ++- testcases/kernel/syscalls/mprotect/mprotect04.c | 5 +++-- testcases/kernel/syscalls/mprotect/mprotect05.c | 4 +++- testcases/kernel/syscalls/mremap/mremap03.c | 5 +++++ testcases/kernel/syscalls/mremap/mremap05.c | 4 +++- testcases/kernel/syscalls/munlock/munlock01.c | 13 +++---------- testcases/kernel/syscalls/munlock/munlock02.c | 1 + 16 files changed, 70 insertions(+), 35 deletions(-) -- 2.43.0
