samples/bpf: Fix build error due to -isystem removal
Since recent Kbuild updates we no longer include files from compiler
directories. However, samples/bpf/hbm_kern.h hasn't been tuned for
this (LLVM 13):
CLANG-bpf samples/bpf/hbm_out_kern.o
In file included from samples/bpf/hbm_out_kern.c:55:
samples/bpf/hbm_kern.h:12:10: fatal error: 'stddef.h' file not found
^~~~~~~~~~
1 error generated.
CLANG-bpf samples/bpf/hbm_edt_kern.o
In file included from samples/bpf/hbm_edt_kern.c:53:
samples/bpf/hbm_kern.h:12:10: fatal error: 'stddef.h' file not found
^~~~~~~~~~
1 error generated.
It is enough to just drop both stdbool.h and stddef.h from includes
to fix those.

Merge branch 'Forbid bpf_ktime_get_coarse_ns and bpf_timer_* in tracing progs'
Dmitrii Banshchikov says: ==================== Various locking issues are possible with bpf_ktime_get_coarse_ns() and bpf_timer_* set of helpers. syzbot found a locking issue with bpf_ktime_get_coarse_ns() helper executed in BPF_PROG_TYPE_PERF_EVENT prog type - [1]. The issue is possible because the helper uses non fast version of time accessor that isn't safe for any context. The helper was added because it provided performance benefits in comparison to bpf_ktime_get_ns() helper. A similar locking issue is possible with bpf_timer_* set of helpers when used in tracing progs. The solution is to restrict use of the helpers in tracing progs. In the [1] discussion it was stated that bpf_spin_lock related helpers shall also be excluded for tracing progs. The verifier has a compatibility check between a map and a program. If a tracing program tries to use a map which value has struct bpf_spin_lock the verifier fails that is why bpf_spin_lock is already restricted. Patch 1 restricts helpers Patch 2 adds tests v1 -> v2: * Limit the helpers via func proto getters instead of allowed callback * Add note about helpers' restrictions to linux/bpf.h * Add Fixes tag * Remove extra \0 from btf_str_sec * Beside asm tests add prog tests * Trim CC 1. https://lore.kernel.org/all/00000000000013aebd05cff8e064@google.com/ ==================== Signed-off-by: Alexei Starovoitov <ast@kernel.org> |

libbpf: Perform map fd cleanup for gen_loader in case of error
Alexei reported a fd leak issue in gen loader (when invoked from
bpftool) [0]. When adding ksym support, map fd allocation was moved from
stack to loader map, however I missed closing these fds (relevant when
cleanup label is jumped to on error). For the success case, the
allocated fd is returned in loader ctx, hence this problem is not
noticed.
Make three changes, first MAX_USED_MAPS in MAX_FD_ARRAY_SZ instead of
MAX_USED_PROGS, the braino was not a problem until now for this case as
we didn't try to close map fds (otherwise use of it would have tried
closing 32 additional fds in ksym btf fd range). Then, do a cleanup for
all nr_maps fds in cleanup label code, so that in case of error all
temporary map fds from bpf_gen__map_create are closed.
Then, adjust the cleanup label to only generate code for the required
number of program and map fds. To trim code for remaining program
fds, lay out prog_fd array in stack in the end, so that we can
directly skip the remaining instances. Still stack size remains same,
since changing that would require changes in a lot of places
(including adjustment of stack_off macro), so nr_progs_sz variable is
only used to track required number of iterations (and jump over
cleanup size calculated from that), stack offset calculation remains
unaffected.
The difference for test_ksyms_module.o is as follows:
libbpf: //prog cleanup iterations: before = 34, after = 5
libbpf: //maps cleanup iterations: before = 64, after = 2
Also, move allocation of gen->fd_array offset to bpf_gen__init. Since
offset can now be 0, and we already continue even if add_data returns 0
in case of failure, we do not need to distinguish between 0 offset and
failure case 0, as we rely on bpf_gen__finish to check errors. We can
also skip check for gen->fd_array in add_*_fd functions, since
bpf_gen__init will take care of it.

samples/bpf: Fix summary per-sec stats in xdp_sample_user
sample_summary_print() uses accumulated period to calculate and display
per-sec averages. This period gets incremented by sampling interval each
time a new sample is formed, and thus equals to the number of samples
collected multiplied by this interval.
However, the totals are being calculated differently, they receive current
sample statistics already divided by the interval gotten as a difference
between sample timestamps for better precision -- in other words, they are
being incremented by the per-sec values each sample.
This leads to the excessive division of summary per-secs when interval != 1
sec. It is obvious pps couldn't become two times lower just from picking a
different sampling interval value:
$ samples/bpf/xdp_redirect_cpu -p xdp_prognum_n1_inverse_qnum -c all
-s -d 6 -i 1
< snip >
Packets received : 2,197,230,321
Average packets/s : 22,887,816
Packets redirected : 2,197,230,472
Average redir/s : 22,887,817
$ samples/bpf/xdp_redirect_cpu -p xdp_prognum_n1_inverse_qnum -c all
-s -d 6 -i 2
< snip >
Packets received : 159,566,498
Average packets/s : 11,397,607
Packets redirected : 159,566,995
Average redir/s : 11,397,642
This can be easily fixed by treating the divisor not as a period, but rather
as a total number of samples, and thus incrementing it by 1 instead of
interval. As a nice side effect, we can now remove so-named argument from a
couple of functions. Let us also create an "alias" for sample_output::rx_cnt::pps
named 'num' using a union since this field is used to store this number (period
previously) as well, and the resulting counter-intuitive code might've been a
reason for this bug.

selftests/bpf: Check map in map pruning
Ensure that two registers with a map_value loaded from a nested map are considered equivalent for the purpose of state pruning and don't cause the verifier to revisit a pruning point. This uses a rather crude match on the number of insns visited by the verifier, which might change in the future. I've therefore tried to keep the code as "unpruneable" as possible by having the code paths only converge on the second to last instruction. Should you require to adjust the test in the future, reducing the number of processed instructions should always be safe. Increasing them could cause another regression, so proceed with caution.

bpf: Fix inner map state pruning regression.
Introduction of map_uid made two lookups from outer map to be distinct.
That distinction is only necessary when inner map has an embedded timer.
Otherwise it will make the verifier state pruning to be conservative
which will cause complex programs to hit 1M insn_processed limit.
Tighten map_uid logic to apply to inner maps with timers only.

xsk: Fix crash on double free in buffer pool
Fix a crash in the buffer pool allocator when a buffer is double
freed. It is possible to trigger this behavior not only from a faulty
driver, but also from user space like this: Create a zero-copy AF_XDP
socket. Load an XDP program that will issue XDP_DROP for all
packets. Put the same umem buffer into the fill ring multiple times,
then bind the socket and send some traffic. This will crash the kernel
as the XDP_DROP action triggers one call to xsk_buff_free()/xp_free()
for every packet dropped. Each call will add the corresponding buffer
entry to the free_list and increase the free_list_cnt. Some entries
will have been added multiple times due to the same buffer being
freed. The buffer allocation code will then traverse this broken list
and since the same buffer is in the list multiple times, it will try
to delete the same buffer twice from the list leading to a crash.
The fix for this is just to test that the buffer has not been added
before in xp_free(). If it has been, just return from the function and
do not put it in the free_list a second time.
Note that this bug was not present in the code before the commit
referenced in the Fixes tag. That code used one list entry per
allocated buffer, so multiple frees did not have any side effects. But
the commit below optimized the usage of the pool and only uses a
single entry per buffer in the umem, meaning that multiple
allocations/frees of the same buffer will also only use one entry,
thus leading to the problem.

mm/migrate.c: remove MIGRATE_PFN_LOCKED
MIGRATE_PFN_LOCKED is used to indicate to migrate_vma_prepare() that a source page was already locked during migrate_vma_collect(). If it wasn't then the a second attempt is made to lock the page. However if the first attempt failed it's unlikely a second attempt will succeed, and the retry adds complexity. So clean this up by removing the retry and MIGRATE_PFN_LOCKED flag. Destination pages are also meant to have the MIGRATE_PFN_LOCKED flag set, but nothing actually checks that.

mm: migrate: simplify the file-backed pages validation when migrating its mapping
There is no need to validate the file-backed page's refcount before trying to freeze the page's expected refcount, instead we can rely on the folio_ref_freeze() to validate if the page has the expected refcount before migrating its mapping. Moreover we are always under the page lock when migrating the page mapping, which means nowhere else can remove it from the page cache, so we can remove the xas_load() validation under the i_pages lock.

mm: allow only SLUB on PREEMPT_RT
Memory allocators may disable interrupts or preemption as part of the allocation and freeing process. For PREEMPT_RT it is important that these sections remain deterministic and short and therefore don't depend on the size of the memory to allocate/ free or the inner state of the algorithm. Until v3.12-RT the SLAB allocator was an option but involved several changes to meet all the requirements. The SLUB design fits better with PREEMPT_RT model and so the SLAB patches were dropped in the 3.12-RT patchset. Comparing the two allocator, SLUB outperformed SLAB in both throughput (time needed to allocate and free memory) and the maximal latency of the system measured with cyclictest during hackbench. SLOB was never evaluated since it was unlikely that it preforms better than SLAB. During a quick test, the kernel crashed with SLOB enabled during boot. Disable SLAB and SLOB on PREEMPT_RT.

Pull exit cleanups from Eric Biederman: "While looking at some issues related to the exit path in the kernel I found several instances where the code is not using the existing abstractions properly. This set of changes introduces force_fatal_sig a way of sending a signal and not allowing it to be caught, and corrects the misuse of the existing abstractions that I found. A lot of the misuse of the existing abstractions are silly things such as doing something after calling a no return function, rolling BUG by hand, doing more work than necessary to terminate a kernel thread, or calling do_exit(SIGKILL) instead of calling force_sig(SIGKILL). In the review a deficiency in force_fatal_sig and force_sig_seccomp where ptrace or sigaction could prevent the delivery of the signal was found. I have added a change that adds SA_IMMUTABLE to change that makes it impossible to interrupt the delivery of those signals, and allows backporting to fix force_sig_seccomp And Arnd found an issue where a function passed to kthread_run had the wrong prototype, and after my cleanup was failing to build." * 'exit-cleanups-for-v5.16' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace: (23 commits) soc: ti: fix wkup_m3_rproc_boot_thread return type signal: Add SA_IMMUTABLE to ensure forced siganls do not get changed signal: Replace force_sigsegv(SIGSEGV) with force_fatal_sig(SIGSEGV) exit/r8188eu: Replace the macro thread_exit with a simple return 0 exit/rtl8712: Replace the macro thread_exit with a simple return 0 exit/rtl8723bs: Replace the macro thread_exit with a simple return 0 signal/x86: In emulate_vsyscall force a signal instead of calling do_exit signal/sparc32: In setup_rt_frame and setup_fram use force_fatal_sig signal/sparc32: Exit with a fatal signal when try_to_clear_window_buffer fails exit/syscall_user_dispatch: Send ordinary signals on failure signal: Implement force_fatal_sig exit/kthread: Have kernel threads return instead of calling do_exit signal/s390: Use force_sigsegv in default_trap_handler signal/vm86_32: Properly send SIGSEGV when the vm86 state cannot be saved. signal/vm86_32: Replace open coded BUG_ON with an actual BUG_ON signal/sparc: In setup_tsb_params convert open coded BUG into BUG signal/powerpc: On swapcontext failure force SIGSEGV signal/sh: Use force_sig(SIGKILL) instead of do_group_exit(SIGKILL) signal/mips: Update (_save|_restore)_fp_context to fail with -EFAULT signal/sparc32: Remove unreachable do_exit in do_sparc_fault ... |

Pull prctl updates from Christian Brauner:
"This contains the missing prctl uapi pieces for PR_SCHED_CORE.
In order to activate core scheduling the caller is expected to specify
the scope of the new core scheduling domain.
For example, passing 2 in the 4th argument of
prctl(PR_SCHED_CORE, PR_SCHED_CORE_CREATE, <pid>, 2, 0);
would indicate that the new core scheduling domain encompasses all
tasks in the process group of <pid>. Specifying 0 would only create a
core scheduling domain for the thread identified by <pid> and 2 would
encompass the whole thread-group of <pid>.
Note, the values 0, 1, and 2 correspond to PIDTYPE_PID, PIDTYPE_TGID,
and PIDTYPE_PGID. A first version tried to expose those values
directly to which I objected because:
- PIDTYPE_* is an enum that is kernel internal which we should not
expose to userspace directly.
- PIDTYPE_* indicates what a given struct pid is used for it doesn't
express a scope.
But what the 4th argument of PR_SCHED_CORE prctl() expresses is the
scope of the operation, i.e. the scope of the core scheduling domain
at creation time. So Eugene's patch now simply introduces three new
defines PR_SCHED_CORE_SCOPE_THREAD, PR_SCHED_CORE_SCOPE_THREAD_GROUP,
and PR_SCHED_CORE_SCOPE_PROCESS_GROUP. They simply express what
happens.
This has been on the mailing list for quite a while with all relevant
scheduler folks Cced. I announced multiple times that I'd pick this up
if I don't see or her anyone else doing it. None of this touches
proper scheduler code but only concerns uapi so I think this is fine.
With core scheduling being quite common now for vm managers (e.g.
moving individual vcpu threads into their own core scheduling domain)
and container managers (e.g. moving the init process into its own core
scheduling domain and letting all created children inherit it) having
to rely on raw numbers passed as the 4th argument in prctl() is a bit
annoying and everyone is starting to come up with their own defines"

The two most recent additions have probably been the ability to use pidfds in bpf maps and the usage of pidfds in mm-based syscalls such as process_mrelease() and process_madvise(). The same pattern to turn a pidfd into a struct task exists in two places. One of those places used PIDTYPE_TGID while the other one used PIDTYPE_PID even though it is clearly documented in all pidfd-helpers that pidfds __currently__ only refer to thread-group leaders (subject to change in the future if need be). This isn't a bug per se but has the potential to be one if we allow pidfds to refer to individual threads. If that happens we want to audit all codepaths that make use of them to ensure they can deal with pidfds refering to individual threads. This adds a simple helper to turn a pidfd into a struct task making it easy to grep for such places. Plus, it gets rid of code-duplication" * tag 'pidfd.v5.16' of git://git.kernel.org/pub/scm/linux/kernel/git/brauner/linux: mm: use pidfd_get_task() pid: add pidfd_get_task() helper |

Pull more ACPI updates from Rafael Wysocki:
"These add support for a new ACPI device configuration object called
_DSC, fix some issues including one recent regression, add two new
items to quirk lists and clean up assorted pieces of code.
Specifics:
- Add support for new ACPI device configuration object called _DSC
("Deepest State for Configuration") to allow certain devices to be
probed without changing their power states, document it and make
two drivers use it (Sakari Ailus, Rajmohan Mani).
- Fix device wakeup power reference counting broken recently by
mistake (Rafael Wysocki).
- Drop unused symbol and macros depending on it from acgcc.h (Rafael
Wysocki).
- Add HP ZHAN 66 Pro to the "no EC wakeup" quirk list (Binbin Zhou).
- Add Xiaomi Mi Pad 2 to the backlight quirk list and drop an unused
piece of data from all of the list entries (Hans de Goede).

chrome platform changes for 5.16
cros_ec_typec:
* Clean up use of cros_ec_check_features
cros_ec_*:
* Rename and move cros_ec_pd_command to cros_ec_command, and make changes to
cros_ec_typec and cros_ec_proto to use the new common command, reducing
duplication.
sensorhub:
* simplify getting .driver_data in cros_ec_sensors_core and cros_ec_sensorhub
misc:
* Maintainership change. Enric Balletbo i Serra has moved on from Collabora,
so removing him from chrome/platform maintainers. Thanks for all of your
hard work maintaining this, Enric, and best of luck to you in your new role!
* Add Prashant Malani as driver maintainer for cros_ec_typec.c and
cros_usbpd_notify. He was already principal contributor of these drivers.
