samples/kretprobes: Fix return value if register_kretprobe() failed
[ Upstream commit f76fbbbb5061fe14824ba5807c44bd7400a6b4e1 ]
Use the actual return value instead of always -1 if register_kretprobe()
failed.
E.g. without this patch:
# insmod samples/kprobes/kretprobe_example.ko func=no_such_func
insmod: ERROR: could not insert module samples/kprobes/kretprobe_example.ko: Operation not permitted
With this patch:
# insmod samples/kprobes/kretprobe_example.ko func=no_such_func
insmod: ERROR: could not insert module samples/kprobes/kretprobe_example.ko: Unknown symbol in module

kfifo: fix ternary sign extension bugs
[ Upstream commit 926ee00ea24320052b46745ef4b00d91c05bd03d ]
The intent with this code was to return negative error codes but instead
it returns positives.
The problem is how type promotion works with ternary operations. These
functions return long, "ret" is an int and "copied" is a u32. The
negative error code is first cast to u32 so it becomes a high positive and
then cast to long where it's still a positive.
We could fix this by declaring "ret" as a ssize_t but let's just get rid
of the ternaries instead.

misc: vop: add round_up(x,4) for vring_size to avoid kernel panic
[ Upstream commit cc1a2679865a94b83804822996eed010a50a7c1d ] Since struct _mic_vring_info and vring are allocated together and follow vring, if the vring_size() is not four bytes aligned, which will cause the start address of struct _mic_vring_info is not four byte aligned. For example, when vring entries is 128, the vring_size() will be 5126 bytes. The _mic_vring_info struct layout in ddr looks like: 0x90002400: 00000000 00390000 EE010000 0000C0FF Here 0x39 is the avail_idx member, and 0xC0FFEE01 is the magic member. When EP use ioread32(magic) to reads the magic in RC's share memory, it will cause kernel panic on ARM64 platform due to the cross-byte io read. Here read magic in user space use le32toh(vr0->info->magic) will meet the same issue. So add round_up(x,4) for vring_size, then the struct _mic_vring_info will store in this way: 0x90002400: 00000000 00000000 00000039 C0FFEE01 Which will avoid kernel panic when read magic in struct _mic_vring_info.

samples: pktgen: fix proc_cmd command result check logic
[ Upstream commit 3cad8f911575191fb3b81d8ed0e061e30f922223 ] Currently, proc_cmd is used to dispatch command to 'pg_ctrl', 'pg_thread', 'pg_set'. proc_cmd is designed to check command result with grep the "Result:", but this might fail since this string is only shown in 'pg_thread' and 'pg_set'. This commit fixes this logic by grep-ing the "Result:" string only when the command is not for 'pg_ctrl'. For clarity of an execution flow, 'errexit' flag has been set. To cleanup pktgen on exit, trap has been added for EXIT signal. Signed-off-by: Daniel T. Lee <danieltimlee@gmail.com> Acked-by: Jesper Dangaard Brouer <brouer@redhat.com> Signed-off-by: David S.

samples, bpf: fix to change the buffer size for read()
[ Upstream commit f7c2d64bac1be2ff32f8e4f500c6e5429c1003e0 ]
If the trace for read is larger than 4096, the return
value sz will be 4096. This results in off-by-one error
on buf:
static char buf[4096];
ssize_t sz;
sz = read(trace_fd, buf, sizeof(buf));
if (sz > 0) {
buf[sz] = 0;
puts(buf);

Commit 6575257c60e1 ("tracing/samples: Fix creation and deletion of
simple_thread_fn creation") introduced a new warning due to using a
boolean as a counter.
Just make it "int".

BACKPORT: bpf: introduce BPF_F_ALLOW_OVERRIDE flag
If BPF_F_ALLOW_OVERRIDE flag is used in BPF_PROG_ATTACH command
to the given cgroup the descendent cgroup will be able to override
effective bpf program that was inherited from this cgroup.
By default it's not passed, therefore override is disallowed.
Examples:
1.
prog X attached to /A with default
prog Y fails to attach to /A/B and /A/B/C
Everything under /A runs prog X
2.
prog X attached to /A with allow_override.
prog Y fails to attach to /A/B with default (non-override)
prog M attached to /A/B with allow_override.
Everything under /A/B runs prog M only.
3.
prog X attached to /A with allow_override.
prog Y fails to attach to /A with default.
The user has to detach first to switch the mode.
In the future this behavior may be extended with a chain of
non-overridable programs.
Also fix the bug where detach from cgroup where nothing is attached
was not throwing error. Return ENOENT in such case.
Add several testcases and adjust libbpf.

UPSTREAM: samples: bpf: add userspace example for attaching eBPF programs to cgroups
Cherry-pick from commit d8c5b17f2bc0de09fbbfa14d90e8168163a579e7 Add a simple userpace program to demonstrate the new API to attach eBPF programs to cgroups. This is what it does: * Create arraymap in kernel with 4 byte keys and 8 byte values * Load eBPF program The eBPF program accesses the map passed in to store two pieces of information. The number of invocations of the program, which maps to the number of packets received, is stored to key 0. Key 1 is incremented on each iteration by the number of bytes stored in the skb. * Detach any eBPF program previously attached to the cgroup * Attach the new program to the cgroup using BPF_PROG_ATTACH * Once a second, read map[0] and map[1] to see how many bytes and packets were seen on any socket of tasks in the given cgroup. The program takes a cgroup path as 1st argument, and either "ingress" or "egress" as 2nd. Optionally, "drop" can be passed as 3rd argument, which will make the generated eBPF program return 0 instead of 1, so the kernel will drop the packet. libbpf gained two new wrappers for the new syscall commands.

bpf: enhance verifier to understand stack pointer arithmetic
[ Upstream commit 332270fdc8b6fba07d059a9ad44df9e1a2ad4529 ] llvm 4.0 and above generates the code like below: .... 440: (b7) r1 = 15 441: (05) goto pc+73 515: (79) r6 = *(u64 *)(r10 -152) 516: (bf) r7 = r10 517: (07) r7 += -112 518: (bf) r2 = r7 519: (0f) r2 += r1 520: (71) r1 = *(u8 *)(r8 +0) 521: (73) *(u8 *)(r2 +45) = r1 .... and the verifier complains "R2 invalid mem access 'inv'" for insn #521. This is because verifier marks register r2 as unknown value after #519 where r2 is a stack pointer and r1 holds a constant value. Teach verifier to recognize "stack_ptr + imm" and "stack_ptr + reg with const val" as valid stack_ptr with new offset.

bpf: Add test for bpf_redirect to ipip/ip6tnl
The test creates two netns, ns1 and ns2. The host (the default netns)
has an ipip or ip6tnl dev configured for tunneling traffic to the ns2.
ping VIPS from ns1 <----> host <--tunnel--> ns2 (VIPs at loopback)
The test is to have ns1 pinging VIPs configured at the loopback
interface in ns2.
The VIPs are 10.10.1.102 and 2401:face::66 (which are configured
at lo@ns2). [Note: 0x66 => 102].
At ns1, the VIPs are routed _via_ the host.
At the host, bpf programs are installed at the veth to redirect packets
from a veth to the ipip/ip6tnl. The test is configured in a way so
that both ingress and egress can be tested.
At ns2, the ipip/ip6tnl dev is configured with the local and remote address
specified. The return path is routed to the dev ipip/ip6tnl.
During egress test, the host also locally tests pinging the VIPs to ensure
that bpf_redirect at egress also works for the direct egress (i.e. not
forwarding from dev ve1 to ve2).

bpf: fix samples to add fake KBUILD_MODNAME
Some of the sample files are causing issues when they are loaded with tc and cls_bpf, meaning tc bails out while trying to parse the resulting ELF file as program/map/etc sections are not present, which can be easily spotted with readelf(1). Currently, BPF samples are including some of the kernel headers and mid term we should change them to refrain from this, really. When dynamic debugging is enabled, we bail out due to undeclared KBUILD_MODNAME, which is easily overlooked in the build as clang spills this along with other noisy warnings from various header includes, and llc still generates an ELF file with mentioned characteristics. For just playing around with BPF examples, this can be a bit of a hurdle to take. Just add a fake KBUILD_MODNAME as a band-aid to fix the issue, same is done in xdp*_kern samples already. Fixes: |

bpf: allow access into map value arrays
Suppose you have a map array value that is something like this
struct foo {
unsigned iter;
int array[SOME_CONSTANT];
};
You can easily insert this into an array, but you cannot modify the contents of
foo->array[] after the fact. This is because we have no way to verify we won't
go off the end of the array at verification time. This patch provides a start
for this work. We accomplish this by keeping track of a minimum and maximum
value a register could be while we're checking the code. Then at the time we
try to do an access into a MAP_VALUE we verify that the maximum offset into that
region is a valid access into that memory region. So in practice, code such as
this
unsigned index = 0;
if (foo->iter >= SOME_CONSTANT)
foo->iter = index;
else
index = foo->iter++;
foo->array[index] = bar;
would be allowed, as we can verify that index will always be between 0 and
SOME_CONSTANT-1. If you wish to use signed values you'll have to have an extra
check to make sure the index isn't less than 0, or do something like index %=
SOME_CONSTANT.

Third namespace creates collect_md tunnel that is driven by BPF program which selects different remote host (either first or second namespace) based on tcp dest port number while tcp dst ip is the same.

rpmsg: rpmsg_send() operations takes rpmsg_endpoint
The rpmsg_send() operations has been taking a rpmsg_device, but this forces users of secondary rpmsg_endpoints to use the rpmsg_sendto() interface - by extracting source and destination from the given data structures. If we instead pass the rpmsg_endpoint to these functions a service can use rpmsg_sendto() to respond to messages, even on secondary endpoints. In addition this would allow us to support operations on multiple channels in future backends that does not support off-channel operations.

bpf: fix range propagation on direct packet access
LLVM can generate code that tests for direct packet access via
skb->data/data_end in a way that currently gets rejected by the
verifier, example:
[...]
7: (61) r3 = *(u32 *)(r6 +80)
8: (61) r9 = *(u32 *)(r6 +76)
9: (bf) r2 = r9
10: (07) r2 += 54
11: (3d) if r3 >= r2 goto pc+12
R1=inv R2=pkt(id=0,off=54,r=0) R3=pkt_end R4=inv R6=ctx
R9=pkt(id=0,off=0,r=0) R10=fp
12: (18) r4 = 0xffffff7a
14: (05) goto pc+430
[...]
from 11 to 24: R1=inv R2=pkt(id=0,off=54,r=0) R3=pkt_end R4=inv
R6=ctx R9=pkt(id=0,off=0,r=0) R10=fp
24: (7b) *(u64 *)(r10 -40) = r1
25: (b7) r1 = 0
26: (63) *(u32 *)(r6 +56) = r1
27: (b7) r2 = 40
28: (71) r8 = *(u8 *)(r9 +20)
invalid access to packet, off=20 size=1, R9(id=0,off=0,r=0)
The reason why this gets rejected despite a proper test is that we
currently call find_good_pkt_pointers() only in case where we detect
tests like rX > pkt_end, where rX is of type pkt(id=Y,off=Z,r=0) and
derived, for example, from a register of type pkt(id=Y,off=0,r=0)
pointing to skb->data. find_good_pkt_pointers() then fills the range
in the current branch to pkt(id=Y,off=0,r=Z) on success.
For above case, we need to extend that to recognize pkt_end >= rX
pattern and mark the other branch that is taken on success with the
appropriate pkt(id=Y,off=0,r=Z) type via find_good_pkt_pointers().
Since eBPF operates on BPF_JGT (>) and BPF_JGE (>=), these are the
only two practical options to test for from what LLVM could have
generated, since there's no such thing as BPF_JLT (<) or BPF_JLE (<=)
that we would need to take into account as well.
After the fix:
[...]
7: (61) r3 = *(u32 *)(r6 +80)
8: (61) r9 = *(u32 *)(r6 +76)
9: (bf) r2 = r9
10: (07) r2 += 54
11: (3d) if r3 >= r2 goto pc+12
R1=inv R2=pkt(id=0,off=54,r=0) R3=pkt_end R4=inv R6=ctx
R9=pkt(id=0,off=0,r=0) R10=fp
12: (18) r4 = 0xffffff7a
14: (05) goto pc+430
[...]
from 11 to 24: R1=inv R2=pkt(id=0,off=54,r=54) R3=pkt_end R4=inv
R6=ctx R9=pkt(id=0,off=0,r=54) R10=fp
24: (7b) *(u64 *)(r10 -40) = r1
25: (b7) r1 = 0
26: (63) *(u32 *)(r6 +56) = r1
27: (b7) r2 = 40
28: (71) r8 = *(u8 *)(r9 +20)
29: (bf) r1 = r8
30: (25) if r8 > 0x3c goto pc+47
R1=inv56 R2=imm40 R3=pkt_end R4=inv R6=ctx R8=inv56
R9=pkt(id=0,off=0,r=54) R10=fp
31: (b7) r1 = 1
[...]
Verifier test cases are also added in this work, one that demonstrates
the mentioned example here and one that tries a bad packet access for
the current/fall-through branch (the one with types pkt(id=X,off=Y,r=0),
pkt(id=X,off=0,r=0)), then a case with good and bad accesses, and two
with both test variants (>, >=).
