bpf: Add map side support for bpf timers.
Restrict bpf timers to array, hash (both preallocated and kmalloced), and lru map types. The per-cpu maps with timers don't make sense, since 'struct bpf_timer' is a part of map value. bpf timers in per-cpu maps would mean that the number of timers depends on number of possible cpus and timers would not be accessible from all cpus. lpm map support can be added in the future. The timers in inner maps are supported. The bpf_map_update/delete_elem() helpers and sys_bpf commands cancel and free bpf_timer in a given map element. Similar to 'struct bpf_spin_lock' BTF is required and it is used to validate that map element indeed contains 'struct bpf_timer'. Make check_and_init_map_value() init both bpf_spin_lock and bpf_timer when map element data is reused in preallocated htab and lru maps. Teach copy_map_value() to support both bpf_spin_lock and bpf_timer in a single map element. There could be one of each, but not more than one. Due to 'one bpf_timer in one element' restriction do not support timers in global data, since global data is a map of single element, but from bpf program side it's seen as many global variables and restriction of single global timer would be odd. The sys_bpf map_freeze and sys_mmap syscalls are not allowed on maps with timers, since user space could have corrupted mmap element and crashed the kernel. The maps with timers cannot be readonly. Due to these restrictions search for bpf_timer in datasec BTF in case it was placed in the global data to report clear error. The previous patch allowed 'struct bpf_timer' as a first field in a map element only. Relax this restriction. Refactor lru map to s/bpf_lru_push_free/htab_lru_push_free/ to cancel and free the timer when lru map deletes an element as a part of it eviction algorithm. Make sure that bpf program cannot access 'struct bpf_timer' via direct load/store. The timer operation are done through helpers only. This is similar to 'struct bpf_spin_lock'.

bpf: Introduce bpf timers.
Introduce 'struct bpf_timer { __u64 :64; __u64 :64; };' that can be embedded
in hash/array/lru maps as a regular field and helpers to operate on it:
// Initialize the timer.
// First 4 bits of 'flags' specify clockid.
// Only CLOCK_MONOTONIC, CLOCK_REALTIME, CLOCK_BOOTTIME are allowed.
long bpf_timer_init(struct bpf_timer *timer, struct bpf_map *map, int flags);
// Configure the timer to call 'callback_fn' static function.
long bpf_timer_set_callback(struct bpf_timer *timer, void *callback_fn);
// Arm the timer to expire 'nsec' nanoseconds from the current time.
long bpf_timer_start(struct bpf_timer *timer, u64 nsec, u64 flags);
// Cancel the timer and wait for callback_fn to finish if it was running.
long bpf_timer_cancel(struct bpf_timer *timer);
Here is how BPF program might look like:
struct map_elem {
int counter;
struct bpf_timer timer;
};
struct {
__uint(type, BPF_MAP_TYPE_HASH);
__uint(max_entries, 1000);
__type(key, int);
__type(value, struct map_elem);
} hmap SEC(".maps");
static int timer_cb(void *map, int *key, struct map_elem *val);
/* val points to particular map element that contains bpf_timer. */
SEC("fentry/bpf_fentry_test1")
int BPF_PROG(test1, int a)
{
struct map_elem *val;
int key = 0;
val = bpf_map_lookup_elem(&hmap, &key);
if (val) {
bpf_timer_init(&val->timer, &hmap, CLOCK_REALTIME);
bpf_timer_set_callback(&val->timer, timer_cb);
bpf_timer_start(&val->timer, 1000 /* call timer_cb2 in 1 usec */, 0);
}
}
This patch adds helper implementations that rely on hrtimers
to call bpf functions as timers expire.
The following patches add necessary safety checks.
Only programs with CAP_BPF are allowed to use bpf_timer.
The amount of timers used by the program is constrained by
the memcg recorded at map creation time.
The bpf_timer_init() helper needs explicit 'map' argument because inner maps
are dynamic and not known at load time. While the bpf_timer_set_callback() is
receiving hidden 'aux->prog' argument supplied by the verifier.
The prog pointer is needed to do refcnting of bpf program to make sure that
program doesn't get freed while the timer is armed. This approach relies on
"user refcnt" scheme used in prog_array that stores bpf programs for
bpf_tail_call. The bpf_timer_set_callback() will increment the prog refcnt which is
paired with bpf_timer_cancel() that will drop the prog refcnt. The
ops->map_release_uref is responsible for cancelling the timers and dropping
prog refcnt when user space reference to a map reaches zero.
This uref approach is done to make sure that Ctrl-C of user space process will
not leave timers running forever unless the user space explicitly pinned a map
that contained timers in bpffs.
bpf_timer_init() and bpf_timer_set_callback() will return -EPERM if map doesn't
have user references (is not held by open file descriptor from user space and
not pinned in bpffs).
The bpf_map_delete_elem() and bpf_map_update_elem() operations cancel
and free the timer if given map element had it allocated.
"bpftool map update" command can be used to cancel timers.
The 'struct bpf_timer' is explicitly __attribute__((aligned(8))) because
'__u64 :64' has 1 byte alignment of 8 byte padding.

bpf: Prepare bpf_prog_put() to be called from irq context.
Currently bpf_prog_put() is called from the task context only. With addition of bpf timers the timer related helpers will start calling bpf_prog_put() from irq-saved region and in rare cases might drop the refcnt to zero. To address this case, first, convert bpf_prog_free_id() to be irq-save (this is similar to bpf_map_free_id), and, second, defer non irq appropriate calls into work queue. For example: bpf_audit_prog() is calling kmalloc and wake_up_interruptible, bpf_prog_kallsyms_del_all()->bpf_ksym_del()->spin_unlock_bh(). They are not safe with irqs disabled.

bpf: Fix potential memleak and UAF in the verifier.
In bpf_patch_insn_data(), we first use the bpf_patch_insn_single() to
insert new instructions, then use adjust_insn_aux_data() to adjust
insn_aux_data. If the old env->prog have no enough room for new inserted
instructions, we use bpf_prog_realloc to construct new_prog and free the
old env->prog.
There have two errors here. First, if adjust_insn_aux_data() return
ENOMEM, we should free the new_prog. Second, if adjust_insn_aux_data()
return ENOMEM, bpf_patch_insn_data() will return NULL, and env->prog has
been freed in bpf_prog_realloc, but we will use it in bpf_check().
So in this patch, we make the adjust_insn_aux_data() never fails. In
bpf_patch_insn_data(), we first pre-malloc memory for the new
insn_aux_data, then call bpf_patch_insn_single() to insert new
instructions, at last call adjust_insn_aux_data() to adjust
insn_aux_data.

libbpf: Fix reuse of pinned map on older kernel
When loading a BPF program with a pinned map, the loader checks whether the pinned map can be reused, i.e. their properties match. To derive such of the pinned map, the loader invokes BPF_OBJ_GET_INFO_BY_FD and then does the comparison. Unfortunately, on < 4.12 kernels the BPF_OBJ_GET_INFO_BY_FD is not available, so loading the program fails with the following error: libbpf: failed to get map info for map FD 5: Invalid argument libbpf: couldn't reuse pinned map at '/sys/fs/bpf/tc/globals/cilium_call_policy': parameter mismatch" libbpf: map 'cilium_call_policy': error reusing pinned map libbpf: map 'cilium_call_policy': failed to create: Invalid argument(-22) libbpf: failed to load object 'bpf_overlay.o' To fix this, fallback to derivation of the map properties via /proc/$PID/fdinfo/$MAP_FD if BPF_OBJ_GET_INFO_BY_FD fails with EINVAL, which can be used as an indicator that the kernel doesn't support the latter.

samples/bpf: xdp_redirect_cpu_user: Cpumap qsize set larger default
Experience from production shows queue size of 192 is too small, as
this caused packet drops during cpumap-enqueue on RX-CPU. This can be
diagnosed with xdp_monitor sample program.
This bpftrace program was used to diagnose the problem in more detail:
bpftrace -e '
tracepoint:xdp:xdp_cpumap_kthread { @deq_bulk = lhist(args->processed,0,10,1); @drop_net = lhist(args->drops,0,10,1) }
tracepoint:xdp:xdp_cpumap_enqueue { @enq_bulk = lhist(args->processed,0,10,1); @enq_drops = lhist(args->drops,0,10,1); }'
Watch out for the @enq_drops counter. The @drop_net counter can happen
when netstack gets invalid packets, so don't despair it can be
natural, and that counter will likely disappear in newer kernels as it
was a source of confusion (look at netstat info for reason of the
netstack @drop_net counters).
The production system was configured with CPU power-saving C6 state.
Learn more in this blogpost[1].
And wakeup latency in usec for the states are:
# grep -H . /sys/devices/system/cpu/cpu0/cpuidle/*/latency
/sys/devices/system/cpu/cpu0/cpuidle/state0/latency:0
/sys/devices/system/cpu/cpu0/cpuidle/state1/latency:2
/sys/devices/system/cpu/cpu0/cpuidle/state2/latency:10
/sys/devices/system/cpu/cpu0/cpuidle/state3/latency:133
Deepest state take 133 usec to wakeup from (133/10^6). The link speed
is 25Gbit/s ((25*10^9/8) in bytes/sec). How many bytes can arrive with
in 133 usec at this speed: (25*10^9/8)*(133/10^6) = 415625 bytes. With
MTU size packets this is 275 packets, and with minimum Ethernet (incl
intergap overhead) 84 bytes it is 4948 packets. Clearly default queue
size is too small.
Setting default cpumap queue to 2048 as worst-case (small packet) at
10Gbit/s is 1979 packets with 133 usec wakeup time, +64 packet before
kthread wakeup call (due to xdp_do_flush) worst-case 2043 packets.
Thus, if a packet burst on RX-CPU will enqueue packets to a remote
cpumap CPU that is in deep-sleep state it can overrun the cpumap queue.
The production system was also configured to avoid deep-sleep via:

bpf: devmap: Implement devmap prog execution for generic XDP
This lifts the restriction on running devmap BPF progs in generic redirect mode. To match native XDP behavior, it is invoked right before generic_xdp_tx is called, and only supports XDP_PASS/XDP_ABORTED/ XDP_DROP actions. We also return 0 even if devmap program drops the packet, as semantically redirect has already succeeded and the devmap prog is the last point before TX of the packet to device where it can deliver a verdict on the packet. This also means it must take care of freeing the skb, as xdp_do_generic_redirect callers only do that in case an error is returned. Since devmap entry prog is supported, remove the check in generic_xdp_install entirely.

bpf: cpumap: Implement generic cpumap
This change implements CPUMAP redirect support for generic XDP programs. The idea is to reuse the cpu map entry's queue that is used to push native xdp frames for redirecting skb to a different CPU. This will match native XDP behavior (in that RPS is invoked again for packet reinjected into networking stack). To be able to determine whether the incoming skb is from the driver or cpumap, we reuse skb->redirected bit that skips generic XDP processing when it is set. To always make use of this, CONFIG_NET_REDIRECT guard on it has been lifted and it is always available. >From the redirect side, we add the skb to ptr_ring with its lowest bit set to 1. This should be safe as skb is not 1-byte aligned. This allows kthread to discern between xdp_frames and sk_buff. On consumption of the ptr_ring item, the lowest bit is unset. In the end, the skb is simply added to the list that kthread is anyway going to maintain for xdp_frames converted to skb, and then received again by using netif_receive_skb_list. Bulking optimization for generic cpumap is left as an exercise for a future patch for now. Since cpumap entry progs are now supported, also remove check in generic_xdp_install for the cpumap.

bitops: Add non-atomic bitops for pointers
cpumap needs to set, clear, and test the lowest bit in skb pointer in various places. To make these checks less noisy, add pointer friendly bitop macros that also do some typechecking to sanitize the argument. These wrap the non-atomic bitops __set_bit, __clear_bit, and test_bit but for pointer arguments. Pointer's address has to be passed in and it is treated as an unsigned long *, since width and representation of pointer and unsigned long match on targets Linux supports. They are prefixed with double underscore to indicate lack of atomicity.

net: core: Split out code to run generic XDP prog
This helper can later be utilized in code that runs cpumap and devmap programs in generic redirect mode and adjust skb based on changes made to xdp_buff. When returning XDP_REDIRECT/XDP_TX, it invokes __skb_push, so whenever a generic redirect path invokes devmap/cpumap prog if set, it must __skb_pull again as we expect mac header to be pulled. It also drops the skb_reset_mac_len call after do_xdp_generic, as the mac_header and network_header are advanced by the same offset, so the difference (mac_len) remains constant.

bpf: Support specifying ingress via xdp_md context in BPF_PROG_TEST_RUN
Support specifying the ingress_ifindex and rx_queue_index of xdp_md contexts for BPF_PROG_TEST_RUN. The intended use case is to allow testing XDP programs that make decisions based on the ingress interface or RX queue. If ingress_ifindex is specified, look up the device by the provided index in the current namespace and use its xdp_rxq for the xdp_buff. If the rx_queue_index is out of range, or is non-zero when the ingress_ifindex is 0, return -EINVAL.

bpf: Support input xdp_md context in BPF_PROG_TEST_RUN
Support passing a xdp_md via ctx_in/ctx_out in bpf_attr for BPF_PROG_TEST_RUN. The intended use case is to pass some XDP meta data to the test runs of XDP programs that are used as tail calls. For programs that use bpf_prog_test_run_xdp, support xdp_md input and output. Unlike with an actual xdp_md during a non-test run, data_meta must be 0 because it must point to the start of the provided user data. From the initial xdp_md, use data and data_end to adjust the pointers in the generated xdp_buff. All other non-zero fields are prohibited (with EINVAL). If the user has set ctx_out/ctx_size_out, copy the (potentially different) xdp_md back to the userspace. We require all fields of input xdp_md except the ones we explicitly support to be set to zero. The expectation is that in the future we might add support for more fields and we want to fail explicitly if the user runs the program on the kernel where we don't yet support them.

Merge branch 'dsa-mv88e6xxx-topaz-fixes'
Marek Behún says: ==================== dsa: mv88e6xxx: Topaz fixes here comes some fixes for the Topaz family (Marvell 88E6141 / 88E6341) which I found out about when I compared the Topaz' operations structure with that one of Peridot (6390). This is v2. In v1, I accidentally sent patches generated from wrong branch and the 5th patch does not contain a necessary change in serdes.c.

net: dsa: return -EOPNOTSUPP when driver does not implement .port_lag_join
The DSA core has a layered structure, and even though we end up returning 0 (success) to user space when setting a bonding/team upper that can't be offloaded, some parts of the framework actually need to know that we couldn't offload that. For example, if dsa_switch_lag_join returns 0 as it currently does, dsa_port_lag_join has no way to tell a successful offload from a software fallback, and it will call dsa_port_bridge_join afterwards. Then we'll think we're offloading the bridge master of the LAG, when in fact we're not even offloading the LAG. In turn, this will make us set skb->offload_fwd_mark = true, which is incorrect and the bridge doesn't like it.

Merge branch 'octeopntx2-LMTST-regions'
Geetha sowjanya says: ==================== Dynamic LMTST region setup This patch series allows RVU PF/VF to allocate memory for LMTST operations instead of using memory reserved by firmware which is mapped as device memory. The LMTST mapping table contains the RVU PF/VF LMTST memory base address entries. This table is used by hardware for LMTST operations.

octeontx2-pf: cn10k: Use runtime allocated LMTLINE region
The current driver uses static LMTST region allocated by firmware. This memory gets populated as PF/VF BAR2. RVU PF/VF driver ioremap the memory as device memory for NIX/NPA operation. Since the memory is mapped as device memory we see performance degration. To address this issue this patch implements runtime memory allocation. RVU PF/VF allocates memory during device probe and share the base address with RVU AF. RVU AF then configure the LMT MAP table accordingly.

octeontx2-af: cn10k: Support configurable LMTST regions
This patch extends the lmtst_tbl_setup_req mbox to support run time LMTST configuration. RVU PF/VF and DPDK/ODP allocates a LMT region, creates a translation entry for a device via VFIO IOCTLs. This IOVA is shared with AF through above mbox. AF then uses RVU_SMMU transulation Widget and gets PA for the IOVA and updates the LMTtable entry for that device.

octeontx2-af: cn10k: Setting up lmtst map table
Introducing a new mailbox to support updating lmt entries
and common lmt base address scheme i.e. multiple pcifuncs
can share lmt region to reduce L1 cache pressure for application.
Parameters passed to mailbox includes the primary pcifunc
value whose lmt regions will be shared by other secondary
pcifuncs. Here secondary pcifunc will be the one who is
calling the mailbox.
For example:
By default each pcifunc has its own LMT base address:
PCIFUNC1 LMT_BASE_ADDR A
PCIFUNC2 LMT_BASE_ADDR B
PCIFUNC3 LMT_BASE_ADDR C
PCIFUNC4 LMT_BASE_ADDR D
Application will choose PCIFUNC1 as base/primary pcifunc
and as and when other pcifunc(secondary pcifuncs) gets
probed, this mailbox will be called and LMTST table will
be updated as:
PCIFUNC1 LMT_BASE_ADDR A
PCIFUNC2 LMT_BASE_ADDR A
PCIFUNC3 LMT_BASE_ADDR A
PCIFUNC4 LMT_BASE_ADDR A
On FLR lmtst map table gets resetted to the default lmt
base addresses for all secondary pcifuncs.

Pull for IPMI driver for 4.14
Mostly a restructure of the kcs_bmc driver to make it easier to
use with different types of devices, and just to clean things up and
improve things.
Also some bug fixes for the kcs_bmc driver.
One fix to the IPMI watchdog to stop the timer when the action is none.
Not a big deal, but it's the right thing to do.
