BACKPORT: bpf: enable program stats
JITed BPF programs are indistinguishable from kernel functions, but unlike kernel code BPF code can be changed often. Typical approach of "perf record" + "perf report" profiling and tuning of kernel code works just as well for BPF programs, but kernel code doesn't need to be monitored whereas BPF programs do. Users load and run large amount of BPF programs. These BPF stats allow tools monitor the usage of BPF on the server. The monitoring tools will turn sysctl kernel.bpf_stats_enabled on and off for few seconds to sample average cost of the programs. Aggregated data over hours and days will provide an insight into cost of BPF and alarms can trigger in case given program suddenly gets more expensive. The cost of two sched_clock() per program invocation adds ~20 nsec. Fast BPF progs (like selftests/bpf/progs/test_pkt_access.c) will slow down from ~10 nsec to ~30 nsec. static_key minimizes the cost of the stats collection. There is no measurable difference before/after this patch with kernel.bpf_stats_enabled=0 Change-Id: If2f51ea469ce232eb67b806514a0a158847ae302 Signed-off-by: Alexei Starovoitov <ast@kernel.org> Signed-off-by: Daniel Borkmann <daniel@iogearbox.net> |

BACKPORT: userfaultfd/sysctl: add vm.unprivileged_userfaultfd
Userfaultfd can be misued to make it easier to exploit existing use-after-free (and similar) bugs that might otherwise only make a short window or race condition available. By using userfaultfd to stall a kernel thread, a malicious program can keep some state that it wrote, stable for an extended period, which it can then access using an existing exploit. While it doesn't cause the exploit itself, and while it's not the only thing that can stall a kernel thread when accessing a memory location, it's one of the few that never needs privilege. We can add a flag, allowing userfaultfd to be restricted, so that in general it won't be useable by arbitrary user programs, but in environments that require userfaultfd it can be turned back on. Add a global sysctl knob "vm.unprivileged_userfaultfd" to control whether userfaultfd is allowed by unprivileged users. When this is set to zero, only privileged users (root user, or users with the CAP_SYS_PTRACE capability) will be able to use the userfaultfd syscalls. Andrea said: : The only difference between the bpf sysctl and the userfaultfd sysctl : this way is that the bpf sysctl adds the CAP_SYS_ADMIN capability : requirement, while userfaultfd adds the CAP_SYS_PTRACE requirement, : because the userfaultfd monitor is more likely to need CAP_SYS_PTRACE : already if it's doing other kind of tracking on processes runtime, in : addition of userfaultfd. In other words both syscalls works only for : root, when the two sysctl are opt-in set to 1.

sched/rt: Disallow writing invalid values to sched_rt_period_us
[ Upstream commit 079be8fc630943d9fc70a97807feb73d169ee3fc ] The validation of the value written to sched_rt_period_us was broken because: - the sysclt_sched_rt_period is declared as unsigned int - parsed by proc_do_intvec() - the range is asserted after the value parsed by proc_do_intvec() Because of this negative values written to the file were written into a unsigned integer that were later on interpreted as large positive integers which did passed the check: if (sysclt_sched_rt_period <= 0) return EINVAL; This commit fixes the parsing by setting explicit range for both perid_us and runtime_us into the sched_rt_sysctls table and processes the values with proc_dointvec_minmax() instead. Alternatively if we wanted to use full range of unsigned int for the period value we would have to split the proc_handler and use proc_douintvec() for it however even the Documentation/scheduller/sched-rt-group.rst describes the range as 1 to INT_MAX. As far as I can tell the only problem this causes is that the sysctl file allows writing negative values which when read back may confuse userspace. There is also a LTP test being submitted for these sysctl files at: http://patchwork.ozlabs.org/project/ltp/patch/20230901144433.2526-1-chrubis@suse.cz/ Signed-off-by: Cyril Hrubis <chrubis@suse.cz> Signed-off-by: Ingo Molnar <mingo@kernel.org> Link: https://lore.kernel.org/r/20231002115553.3007-2-chrubis@suse.cz [ pvorel: rebased for 4.19 ] Reviewed-by: Petr Vorel <pvorel@suse.cz> Signed-off-by: Petr Vorel <pvorel@suse.cz> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> (cherry picked from commit 2d931472d4740d3ada7011cc4c3499948d3a22fa) Signed-off-by: Harshit Mogalapalli <harshit.m.mogalapalli@oracle.com> |

proc: proc_skip_spaces() shouldn't think it is working on C strings
commit bce9332220bd677d83b19d21502776ad555a0e73 upstream. proc_skip_spaces() seems to think it is working on C strings, and ends up being just a wrapper around skip_spaces() with a really odd calling convention. Instead of basing it on skip_spaces(), it should have looked more like proc_skip_char(), which really is the exact same function (except it skips a particular character, rather than whitespace). So use that as inspiration, odd coding and all. Now the calling convention actually makes sense and works for the intended purpose.

proc: avoid integer type confusion in get_proc_long
commit e6cfaf34be9fcd1a8285a294e18986bfc41a409c upstream. proc_get_long() is passed a size_t, but then assigns it to an 'int' variable for the length. Let's not do that, even if our IO paths are limited to MAX_RW_COUNT (exactly because of these kinds of type errors). So do the proper test in the rigth type.

kernel: sysctl: make drop_caches write-only
[ Upstream commit 204cb79ad42f015312a5bbd7012d09c93d9b46fb ]
Currently, the drop_caches proc file and sysctl read back the last value
written, suggesting this is somehow a stateful setting instead of a
one-time command. Make it write-only, like e.g. compact_memory.
While mitigating a VM problem at scale in our fleet, there was confusion
about whether writing to this file will permanently switch the kernel into
a non-caching mode. This influences the decision making in a tense
situation, where tens of people are trying to fix tens of thousands of
affected machines: Do we need a rollback strategy? What are the
performance implications of operating in a non-caching state for several
days? It also caused confusion when the kernel team said we may need to
write the file several times to make sure it's effective ("But it already
reads back 3?").

kernel: sysctl: make drop_caches write-only
[ Upstream commit 204cb79ad42f015312a5bbd7012d09c93d9b46fb ]
Currently, the drop_caches proc file and sysctl read back the last value
written, suggesting this is somehow a stateful setting instead of a
one-time command. Make it write-only, like e.g. compact_memory.
While mitigating a VM problem at scale in our fleet, there was confusion
about whether writing to this file will permanently switch the kernel into
a non-caching mode. This influences the decision making in a tense
situation, where tens of people are trying to fix tens of thousands of
affected machines: Do we need a rollback strategy? What are the
performance implications of operating in a non-caching state for several
days? It also caused confusion when the kernel team said we may need to
write the file several times to make sure it's effective ("But it already
reads back 3?").

trace/irq: sched: irq trace events should be used with !PROVE_LOCKING
When enabling PROVE_LOCKING, kernel build fails due to undefined symbol error for the irqsoff_tracing_threshold_ns which is used in sysctl interface,sysctl_irqsoff_tracing_threshold_ns. As per PREEMPTIRQ_EVENTS Kconfig help, for tracing irq disable/enable events CONFIG_PROVE_LOCKING should be disabled. This commit fixes by making the proc entry under the PROVE_LOCKING config.

sysctl: return -EINVAL if val violates minmax
[ Upstream commit e260ad01f0aa9e96b5386d5cd7184afd949dc457 ] Currently when userspace gives us a values that overflow e.g. file-max and other callers of __do_proc_doulongvec_minmax() we simply ignore the new value and leave the current value untouched. This can be problematic as it gives the illusion that the limit has indeed be bumped when in fact it failed. This commit makes sure to return EINVAL when an overflow is detected. Please note that this is a userspace facing change.

kernel/sysctl.c: fix out-of-bounds access when setting file-max
commit 9002b21465fa4d829edfc94a5a441005cffaa972 upstream.
Commit 32a5ad9c2285 ("sysctl: handle overflow for file-max") hooked up
min/max values for the file-max sysctl parameter via the .extra1 and
.extra2 fields in the corresponding struct ctl_table entry.
Unfortunately, the minimum value points at the global 'zero' variable,
which is an int. This results in a KASAN splat when accessed as a long
by proc_doulongvec_minmax on 64-bit architectures:

Fix the splat by introducing a unsigned long 'zero_ul' and using that
instead.

sysctl: handle overflow for file-max
[ Upstream commit 32a5ad9c22852e6bd9e74bdec5934ef9d1480bc5 ] Currently, when writing echo 18446744073709551616 > /proc/sys/fs/file-max /proc/sys/fs/file-max will overflow and be set to 0. That quickly crashes the system. This commit sets the max and min value for file-max. The max value is set to long int. Any higher value cannot currently be used as the percpu counters are long ints and not unsigned integers. Note that the file-max value is ultimately parsed via __do_proc_doulongvec_minmax(). This function does not report error when min or max are exceeded. Which means if a value largen that long int is written userspace will not receive an error instead the old value will be kept. There is an argument to be made that this should be changed and __do_proc_doulongvec_minmax() should return an error when a dedicated min or max value are exceeded. However this has the potential to break userspace so let's defer this to an RFC patch.

kernel/sysctl.c: add missing range check in do_proc_dointvec_minmax_conv
commit 8cf7630b29701d364f8df4a50e4f1f5e752b2778 upstream. This bug has apparently existed since the introduction of this function in the pre-git era (4500e91754d3 in Thomas Gleixner's history.git, "[NET]: Add proc_dointvec_userhz_jiffies, use it for proper handling of neighbour sysctls."). As a minimal fix we can simply duplicate the corresponding check in do_proc_dointvec_conv().

proc/sysctl: fix return error for proc_doulongvec_minmax()
[ Upstream commit 09be178400829dddc1189b50a7888495dd26aa84 ]
If the number of input parameters is less than the total parameters, an
EINVAL error will be returned.
For example, we use proc_doulongvec_minmax to pass up to two parameters
with kern_table:
{
.procname = "monitor_signals",
.data = &monitor_sigs,
.maxlen = 2*sizeof(unsigned long),
.mode = 0644,
.proc_handler = proc_doulongvec_minmax,
},
Reproduce:
When passing two parameters, it's work normal. But passing only one
parameter, an error "Invalid argument"(EINVAL) is returned.
[root@cl150 ~]# echo 1 2 > /proc/sys/kernel/monitor_signals
[root@cl150 ~]# cat /proc/sys/kernel/monitor_signals
1 2
[root@cl150 ~]# echo 3 > /proc/sys/kernel/monitor_signals
-bash: echo: write error: Invalid argument
[root@cl150 ~]# echo $?
1
[root@cl150 ~]# cat /proc/sys/kernel/monitor_signals
3 2
[root@cl150 ~]#
The following is the result after apply this patch. No error is
returned when the number of input parameters is less than the total
parameters.
[root@cl150 ~]# echo 1 2 > /proc/sys/kernel/monitor_signals
[root@cl150 ~]# cat /proc/sys/kernel/monitor_signals
1 2
[root@cl150 ~]# echo 3 > /proc/sys/kernel/monitor_signals
[root@cl150 ~]# echo $?
0
[root@cl150 ~]# cat /proc/sys/kernel/monitor_signals
3 2
[root@cl150 ~]#
There are three processing functions dealing with digital parameters,
__do_proc_dointvec/__do_proc_douintvec/__do_proc_doulongvec_minmax.
This patch deals with __do_proc_doulongvec_minmax, just as
__do_proc_dointvec does, adding a check for parameters 'left'. In
__do_proc_douintvec, its code implementation explicitly does not support
multiple inputs.
static int __do_proc_douintvec(...){
...
/*
* Arrays are not supported, keep this simple. *Do not* add
* support for them.
*/
if (vleft != 1) {
*lenp = 0;
return -EINVAL;
}
...
}
So, just __do_proc_doulongvec_minmax has the problem. And most use of
proc_doulongvec_minmax/proc_doulongvec_ms_jiffies_minmax just have one
parameter.

sysctl: Limit sched_upmigrate/sched_downmigrate tunables range
The sched_upmigrate/sched_downmigrate tunable values are accepted in percentage. Hence don't accept any values greater than 100. The sched_upmigrate is also used to check if a CPU is overutilized or not. Accepting a large value for this tunable makes a heavily loaded CPU not getting classified as overutilized. Since the CPUs are not overutilized, the higher capacity CPUs does not offer help to the heavily loaded lower capacity CPUs. The no-hz idle balance kicks are also not sent to the CPUs with in the same cluster. This results in starvation.

namei: allow restricted O_CREAT of FIFOs and regular files
commit 30aba6656f61ed44cba445a3c0d38b296fa9e8f5 upstream. Disallows open of FIFOs or regular files not owned by the user in world writable sticky directories, unless the owner is the same as that of the directory or the file is opened without the O_CREAT flag. The purpose is to make data spoofing attacks harder. This protection can be turned on and off separately for FIFOs and regular files via sysctl, just like the symlinks/hardlinks protection. This patch is based on Openwall's "HARDEN_FIFO" feature by Solar Designer. This is a brief list of old vulnerabilities that could have been prevented by this feature, some of them even allow for privilege escalation: CVE-2000-1134 CVE-2007-3852 CVE-2008-0525 CVE-2009-0416 CVE-2011-4834 CVE-2015-1838 CVE-2015-7442 CVE-2016-7489 This list is not meant to be complete. It's difficult to track down all vulnerabilities of this kind because they were often reported without any mention of this particular attack vector. In fact, before hardlinks/symlinks restrictions, fifos/regular files weren't the favorite vehicle to exploit them.

hung task: check specific tasks for long uninterruptible sleep state
khungtask by default monitors all tasks for long unterruptible sleep. This change introduces a sysctl option, /proc/sys/kernel/ hung_task_selective_monitoring, to enable monitoring selected tasks. If this sysctl option is enabled then only the tasks with /proc/$PID/hang_detection_enabled set are to be monitored, otherwise all tasks are monitored as default case. Some tasks may intentionally moves to uninterruptable sleep state, which shouldn't leads to khungtask panics, as those are recoverable hungs. So to avoid false hung reports, add an option to select tasks to be monitored and report/panic them only. By default, enable the feature always to monitor selected tasks.

sysctl/sched: do not allow value "0" for sched_{up,down}_migrate knobs
Right now sched_{up,down}_migrate knobs are accepting zero as a valid
value and we end up with upmigrate value is less than downmigrate value
when zero is written by user to upmigrate knob, we go ahead and update
upmigrate value which would end up being lesser than downmigrate value.
Also, there is a div by zero issue by accepting zero as valid value for
these knobs.
So, update check to make sure zero isn't allowed as a valid value.

sched/core: fix userspace affining threads incorrectly
Certain userspace applications, to achieve max performance, affines its threads to cpus that run the fastest. This is not always the correct strategy. For e.g. in certain architectures all the cores have the same max freq but few of them have a bigger cache. Affining to the cpus that have bigger cache is advantageous but such an application would end up affining them to all the cores. Similarly if an architecture has just one cpu that runs at max freq, it ends up crowding all its thread on that single core, which is detrimental for performance. To address this issue, we need to detect a suspicious looking affinity request from userspace and check if it links in a particular library. The latter can easily be detected by traversing executable vm areas that map a file and checking for that library name. When such a affinity request is found, change it to use a proper affinity. The suspicious affinity request, the proper affinity request and the library name can be configured by the userspace.

sched: kill sched_use_walt_cpu_{task_}util sysctl knobs
sched_use_walt_cpu_{task_}util sysctl knobs are used to control
runtime whether to use WALT signals (cumulative_runnable_avg/
ravg.demand) or PELT signal (util_avg) for task and cpu utilization
for task placement and frequency guidance.
But there is a subtle impact with these tunables when we frequently
toggle them. When sched_use_walt_cpu_util set to 0, and hotplugging
the cpu makes sg_cpu() members reset to 0, which sets sg_cpu.walt_load
to 0, but the sg_policy->last_ws never reset to zero. When the knob is
set back to 1 exactly after load is queried but before sugov_calc_avg_cap()
is called, which would compare walt_load->ws (= 0) against the stale
value of sg_policy->last_ws and hits BUG_ON().
When walt is enabled, we always use walt signals for task placement and
frequency guidance. So kill these sysctl knobs.
