[PATCH net-next v2 7/8] selftests: net: lib: Add kill_process

by Petr Machata

A number of selftests run processes in the background and need to kill them afterwards. Instead for everyone to open-code the kill / wait / redirect mantra, add a helper in net/lib.sh. Convert existing open-code sites.

[PATCH net-next v2 6/8] selftests: net: lib: Move checks from forwarding/lib.sh here

by Petr Machata

For logging to be useful, something has to set RET and retmsg by calling ret_set_ksft_status(). There is a suite of functions to that end in forwarding/lib: check_err, check_fail et.al. Move them to net/lib.sh so that every net test can use them. Existing lib.sh users might be using these same names for their functions. However lib.sh is always sourced near the top of the file (checked), and whatever new definitions will simply override the ones provided by lib.sh.

[PATCH net-next v2 5/8] selftests: net: lib: Move tests_run from forwarding/lib.sh here

It would be good to use the same mechanism for scheduling and dispatching general net tests as the many forwarding tests already use. To that end, move the logging helpers to net/lib.sh so that every net test can use them. Existing lib.sh users might be using the name themselves.

[PATCH net-next v2 4/8] selftests: net: lib: Move logging from forwarding/lib.sh here

by Petr Machata

Many net selftests invent their own logging helpers. These really should be in a library sourced by these tests. Currently forwarding/lib.sh has a suite of perfectly fine logging helpers, but sourcing a forwarding/ library from a higher-level directory smells of layering violation. In this patch, move the logging helpers to net/lib.sh so that every net test can use them. Together with the logging helpers, it's also necessary to move pause_on_fail(), and EXIT_STATUS and RET. Existing lib.sh users might be using these same names for their functions or variables. However lib.sh is always sourced near the top of the file (checked), and whatever new definitions will simply override the ones provided by lib.sh.

[PATCH] sched_ext: Fix function pointer type mismatches in BPF selftests

by Vishal Chourasia

Fix incompatible function pointer type warnings in sched_ext BPF selftests by explicitly casting the function pointers when initializing struct_ops. This addresses multiple -Wincompatible-function-pointer-types warnings from the clang compiler where function signatures didn't match exactly. The void * cast ensures the compiler accepts the function pointer assignment despite minor type differences in the parameters.

[PATCH v3] selftest: remoteproc: Add test for start/stop sequence

by Wasim Nazir

Add test to validate end-to-end start/stop sequence for each remoteproc instances available on target. Add first test sequence to validated each instance sequencially to identify any issue while booting each instance. Add second test sequence to validate all instances concurrently to identify any race scenario within instances doing bootup. Additional user argument (--seqdelay) is available to add delay is seconds, between start/stop sequence. This is added as different target might have different threshold to start any instance (default is 5 secs).

[PATCH net-next] selftests: tls: add a selftest for wrapping rec_seq

Set the initial rec_seq to 0xffffffffffffffff so that it wraps immediately. The send() call should fail with EBADMSG.

[PATCH RFC v2 0/4] mm: Introduce MAP_BELOW_HINT

by Charlie Jenkins

Some applications rely on placing data in free bits addresses allocated by mmap. Various architectures (eg. x86, arm64, powerpc) restrict the address returned by mmap to be less than the 48-bit address space, unless the hint address uses more than 47 bits (the 48th bit is reserved for the kernel address space). The riscv architecture needs a way to similarly restrict the virtual address space. On the riscv port of OpenJDK an error is thrown if attempted to run on the 57-bit address space, called sv57 [1]. golang has a comment that sv57 support is not complete, but there are some workarounds to get it to mostly work [2]. These applications work on x86 because x86 does an implicit 47-bit restriction of mmap() address that contain a hint address that is less than 48 bits. Instead of implicitly restricting the address space on riscv (or any current/future architecture), a flag would allow users to opt-in to this behavior rather than opt-out as is done on other architectures. This is desirable because it is a small class of applications that do pointer masking. This flag will also allow seemless compatibility between all architectures, so applications like Go and OpenJDK that use bits in a virtual address can request the exact number of bits they need in a generic way. The flag can be checked inside of vm_unmapped_area() so that this flag does not have to be handled individually by each architecture.

[PATCH net-next 4/8] selftests: net: lib: Move logging from forwarding/lib.sh here

by Petr Machata

Many net selftests invent their own logging helpers. These really should be in a library sourced by these tests. Currently forwarding/lib.sh has a suite of perfectly fine logging helpers, but sourcing a forwarding/ library from a higher-level directory smells of layering violation. In this patch, move the logging helpers to net/lib.sh so that every net test can use them. Together with the logging helpers, it's also necessary to move pause_on_fail(), and EXIT_STATUS and RET. Existing lib.sh users might be using these same names for their functions or variables. However lib.sh is always sourced near the top of the file (checked), and whatever new definitions will simply override the ones provided by lib.sh.
