The rcu_torture_one_read() function is designed for RCU readers that are
confined to a task, such that a single thread of control extends from the
beginning of a given RCU read-side critical section to its end. This does
not suffice for things like srcu_down_read() and srcu_up_read(), where

compact the mm_cid for each process. Add a test to validate that it runs
correctly and timely.
The test spawns 1 thread pinned to each CPU, then each thread, including
the main one, runs in short bursts for some time. During thi

Hello!
The following series improves testing of SRCU-fast and SRCU up/down:
1. Make srcu_lockdep.sh check kernel Kconfig.
2. Make srcu_lockdep.sh check reader-conflict handling.
3. Split out beginning and end from rcu_torture_one_read().
4. Make torture.sh --do-rt use CONFI
The torture.sh --do-rt command-line parameter is intended to mimic -rt
kernels. Now that CONFIG_PREEMPT_RT is upstream, this commit makes this
mimicking more precise.
Note that testing of RCU priority boosting is disabled in favor
of forward-progress testing of RCU callbacks. If it turns out to
The rcu_torture_reader() and rcu_torture_fwd_prog_cr() functions
run CPU-bound for extended periods of time (tens or even
hundreds of milliseconds), so they invoke tick_dep_set_task() and
tick_dep_clear_task() to ensure that the scheduling-clock tick helps
move grace periods forward.
So why doesn'

The get->num_services variable is an unsigned int which is controlled by

does not overflow an unsigned long, however, we are saving the result to

This commit adds a new rcutorture.n_up_down kernel boot parameter
that specifies the number of outstanding SRCU up/down readers, which
begin in kthread context and end in an hrtimer handler. There is a new
kthread ("rcu_torture_updown") that scans an per-reader array looking
for elements whose rea
This test exercises the kernel flag added to security_bpf by
effectively blocking light-skeletons from loading while allowing
normal skeletons to function as-is. Since this should work with any
arbitrary BPF program, an existing program from LSKELS_EXTRA was
used as a test payload.
Signed-off-by:
Certain bpf syscall subcommands are available for usage from both
userspace and the kernel. LSM modules or eBPF gatekeeper programs may
need to take a different course of action depending on whether or not
a BPF syscall originated from the kernel or userspace.
Additionally, some of the bpf_attr st
This is strictly a code-movement commit, pulling that part of
the rcu_torture_updown() function's loop body that processes
one rcu_torture_one_read_state_updown structure into a new
