This series is a major rework of previously submitted libbpf
patches [0] in order to add global data support for BPF. The
kernel has been extended to add proper infrastructure that allows
for full .bss/.data/.rodata sections on BPF loader side based
upon feedback from LPC discussions [1]. Latter support is then
also added into libbpf in this series which allows for more
natural C-like programming of BPF programs. For more information
on loader, please refer to 'bpf, libbpf: support global data/bss/
rodata sections' patch in this series. Joint work with Joe Stringer.
Thanks a lot!
v1 -> v2:
- Instead of 32-bit static data, implement full global
data support.

This generic extension to BPF maps allows for directly loading an
address residing inside a BPF map value as a single BPF ldimm64
instruction.
The idea is similar to what BPF_PSEUDO_MAP_FD does today, which
is a special src_reg flag for ldimm64 instruction that indicates
that inside the first part of the double insns's imm field is a
file descriptor which the verifier then replaces as a full 64bit
address of the map into both imm parts.
For the newly added BPF_PSEUDO_MAP_VALUE src_reg flag, the idea
is similar: the first part of the double insns's imm field is
again a file descriptor corresponding to the map, and the second
part of the imm field is an offset. The verifier will then replace
both imm parts with an address that points into the BPF map value
for maps that support this operation. BPF_PSEUDO_MAP_VALUE is a
distinct flag as otherwise with BPF_PSEUDO_MAP_FD we could not
differ offset 0 between load of map pointer versus load of map's
value at offset 0.
This allows for efficiently retrieving an address to a map value
memory area without having to issue a helper call which needs to
prepare registers according to calling convention, etc, without
needing the extra NULL test, and without having to add the offset
in an additional instruction to the value base pointer.
The verifier then treats the destination register as PTR_TO_MAP_VALUE
with constant reg->off from the user passed offset from the second
imm field, and guarantees that this is within bounds of the map
value. Any subsequent operations are normally treated as typical
map value handling without anything else needed for verification.
The two map operations for direct value access have been added to
array map for now. In future other types could be supported as
well depending on the use case. The main use case for this commit
is to allow for BPF loader support for global variables that
reside in .data/.rodata/.bss sections such that we can directly
load the address of them with minimal additional infrastructure
required. Loader support has been added in subsequent commits for
libbpf library.

This work adds two new map creation flags BPF_F_RDONLY_PROG
and BPF_F_WRONLY_PROG in order to allow for read-only or
write-only BPF maps from a BPF program side.
Today we have BPF_F_RDONLY and BPF_F_WRONLY, but this only
applies to system call side, meaning the BPF program has full
read/write access to the map as usual while bpf(2) calls with
map fd can either only read or write into the map depending
on the flags. BPF_F_RDONLY_PROG and BPF_F_WRONLY_PROG allows
for the exact opposite such that verifier is going to reject
program loads if write into a read-only map or a read into a
write-only map is detected.
We've enabled this generic map extension to various non-special
maps holding normal user data: array, hash, lru, lpm, local
storage, queue and stack. Further map types could be followed
up in future depending on use-case. Main use case here is to
forbid writes into .rodata map values from verifier side.

Trivial addition to allow '.' aside from '_' as "special" characters
in the object name. Used to name maps from loader side as ".bss",
".data", ".rodata".

Adjust the code for relocations slightly with no functional changes,
so that upcoming patches that will introduce support for relocations
into the .data, .rodata and .bss sections can be added independent
of these changes.

This work adds BPF loader support for global data sections
to libbpf. This allows to write BPF programs in more natural
C-like way by being able to define global variables and const
data.
Back at LPC 2018 [0] we presented a first prototype which
implemented support for global data sections by extending BPF
syscall where union bpf_attr would get additional memory/size
pair for each section passed during prog load in order to later
add this base address into the ldimm64 instruction along with
the user provided offset when accessing a variable. Consensus
from LPC was that for proper upstream support, it would be
more desirable to use maps instead of bpf_attr extension as
this would allow for introspection of these sections as well
as potential life updates of their content. This work follows
this path by taking the following steps from loader side:
1) In bpf_object__elf_collect() step we pick up ".data",
".rodata", and ".bss" section information.
2) If present, in bpf_object__init_global_maps() we create
a map that corresponds to each of the present sections.
Given section size and access properties can differ, a
single entry array map is created with value size that
is corresponding to the ELF section size of .data, .bss
or .rodata. In the latter case, the map is created as
read-only from program side such that verifier rejects
any write attempts into .rodata. In a subsequent step,
for .data and .rodata sections, the section content is
copied into the map through bpf_map_update_elem(). For
.bss this is not necessary since array map is already
zero-initialized by default.
3) In bpf_program__collect_reloc() step, we record the
corresponding map, insn index, and relocation type for
the global data.
4) And last but not least in the actual relocation step in
bpf_program__relocate(), we mark the ldimm64 instruction
with src_reg = BPF_PSEUDO_MAP_VALUE where in the first
imm field the map's file descriptor is stored as similarly
done as in BPF_PSEUDO_MAP_FD, and in the second imm field
(as ldimm64 is 2-insn wide) we store the access offset
into the section.
5) On kernel side, this special marked BPF_PSEUDO_MAP_VALUE
load will then store the actual target address in order
to have a 'map-lookup'-free access. That is, the actual
map value base address + offset. The destination register
in the verifier will then be marked as PTR_TO_MAP_VALUE,
containing the fixed offset as reg->off and backing BPF
map as reg->map_ptr. Meaning, it's treated as any other
normal map value from verification side, only with
efficient, direct value access instead of actual call to
map lookup helper as in the typical case.
Simple example dump of program using globals vars in each
section:

For now .data/.rodata/.bss maps are not exposed via API to the
user, but this could be done in a subsequent step.
Based upon recent fix in LLVM, commit c0db6b6bd444 ("[BPF] Don't
fail for static variables").

Extend test_verifier with various test cases around the two kernel
extensions, that is, {rd,wr}only map support as well as direct map
value access. All passing, one skipped due to xskmap not present
on test machine:
# ./test_verifier
[...]
#913/p XDP pkt read, pkt_data <= pkt_meta', bad access 1 OK
#914/p XDP pkt read, pkt_data <= pkt_meta', bad access 2 OK
Summary: 1352 PASSED, 1 SKIPPED, 0 FAILED

Can we use <main prog>.bss/data/rodata names? If we load more than one
prog with global data that should make it easier to find which one is which.

Yeah that's fine, we can change it. They could potentially also be shared,
so <main prog>.bss/data/rodata might be misleading, but <obj>.bss/data/rodata
could be.

All these error returns need fdput(f), I think.

This will also enable optimizing the accesses on system with rich

minor nit: we do check that old RDONLY and WRONLY are not set at the

This is great! I'm going to review code more thoroughly tomorrow, but
I also have few questions/suggestions I'd like to discuss, if you

Is having both BPF_PSEUDO_MAP_FD and BPF_PSEUDO_MAP_VALUE a desirable
thing? I'm asking because it's seems like it would be really simple to
stick to using just BPF_PSEUDO_MAP_FD and then interpret imm
differently depending on whether it's 0 or not. E.g., we can say that
imm=0 is old BPF_PSEUDO_MAP_FD behavior (loading map addr), but any
other imm value X is really just (X-1) offset into map's value? Or,
given that valid offset is limited to 1<<29, we can set highest-order
bit to 1 and lower bits would be offset? In other words, if we just
need too carve out zero as a special case, then it's easy to do and we
can avoid adding new BPF_PSEUDO_MAP_VALUE.

It seems like we allow this only for arrays of size 1 right now. We
can easily generalize this to support not just offset into map's
value, but also specifying integer key (i.e., array index) by
utilizing off fields (16-bit + 16-bit). This would allow to eliminate
any bpf_map_update_elem calls to array maps altogether by allowing to
provide both array index and offset into value in one BPF instruction.
Do you think it's a good addition?

I was considering adding a new kind of map representing contiguous
block of memory (e.g., how about BPF_MAP_TYPE_HEAP or
BPF_MAP_TYPE_BLOB?). It's keys would be offset into that memory
region. Value size is size of the memory region, but it would allow
reading smaller chunks of memory as values. This would provide
convenient interface for poking at global variables from userland,
given offset.
Libbpf itself would provide higher-level API as well, if there is
corresponding BTF type information describing layout of
.data/.bss/.rodata, so that applications can fetch variables by name
and/or offset, whichever is more convenient. Together with
bpf_spinlock this would allow easy way to customize subsets of global
variables in atomic fashion.
Do you think that would work? Using array is a bit limiting, because
it doesn't allow to do partial reads/updates, while BPF_MAP_TYPE_HEAP
would be single big value that allows partial reading/updating.

Is there any reason names are so restrictive? Say, why not '-' as
well? It's perfectly safe even in filenames. Or even '/' and '\'? Is
this name used by anything else in the system, except for
introspection?

Is there any point in having .data and .bss in separate maps? I can
only see for reasons of inspectiion from bpftool, but other than that
isn't .bss just an optimization over .data to save space in ELF file,
but in other regards is just another part of r/w .data section?

For .rodata, ideally it would be nice to make it RDONLY from userland
as well, except for first UPDATE. How hard is it to support that?

See comment about BPF_MAP_TYPE_HEAP/BLOB map in comments to patch #1,
it would probably make more useful API for .data/.rodata/.bss.

All three of those are essentially the same relocations, just applied
against different ELF sections.
I think by having just single RELO_GLOBAL_DATA you can actually
simplify a bunch of code below, please see corresponding comments.

Global maps could be stored in maps, along other ones, so that we
don't need to keep track of them separately.
Another inconvenience of having a separate array of global maps is
that bpf_map__iter won't iterate them. I don't know if that's
desirable behavior or not, but it probably would be nice to iterate
over global ones as well?

Instead of deducing flags and looking up for map by index, you can
just pass struct bpf_map * directly instead of int i and provide
flags, instead of type.

This looks like a good candidate for separate static function? It can
also be reused below to check if there is any global map present.

If nr_maps_global is 0, calloc might or might not return NULL, so this
check might erroneously return error.

Here we know exactly what type of map we are creating, so we can just
directly pass all the required structs/flags/data.
Also, to speed up and simplify relocation processing below, I think
it's better to store map indexes for each of available .bss, .data and
.rodata maps, eliminating another need for having three different
types of data relocations.

Previously if we encountered unknown PROGBITS section, we'd emit debug

We don't need to handle all of this if we just remember global map
indicies during creation, instead of calculating type, we can just
pick correct index (and check it exists). And type can be just generic
RELO_DATA.

I'm sorry if I seem a bit too obsessed with those three new relocation
types. I just believe that having one generic and storing global maps
along with other maps is cleaner and more uniform.

Good point indeed, I'll fix it in a v3 such that an invalid combination of
both, BPF_F_RDONLY_PROG | BPF_F_WRONLY_PROG, is rejected upon map creation.

Could be done, presumably it was more restrictive in case one might
need some reserved names in unforeseeable future, but looks so far
noone run into the need to extend it further than this. :)

Was thinking about reusing BPF_PSEUDO_MAP_FD initially as mentioned in
here, but went for BPF_PSEUDO_MAP_VALUE eventually to have a straight
forward mapping. Your suggestion could be done, but it feels more
complex than necessary, imho, meaning it might confuse users trying to
make sense of a insn dump or verifier output wondering whether the off
by one is a bug or not, which won't happen if the offset is exactly the
same value as LLVM emits. There is also one more unfortunate reason
which I noticed while implementing: in replace_map_fd_with_map_ptr()
we never enforced that for BPF_PSEUDO_MAP_FD insns the second imm part
must be 0, meaning it could also have a garbage value which would then
break loaders in the wild; with the code today this is ignored and then
overridden by the map address. We could try to push a patch to stable
to reject anything non-zero in the second imm for BPF_PSEUDO_MAP_FD
and see if anyone actually notices, and then use some higher-order bit
as a selector, but that still would need some extra handling to make
the offset clear for users wrt dumps; I can give it a try though to
check how much more complex it gets. Worst case if something should
really break somewhere, we might need to revert the imm==0 rejection
though. Overall, BPF_PSEUDO_MAP_VALUE felt slightly more suitable to me.

Yeah, I've been thinking about this as well that for array-like maps
it's easy to support and at the same time lifts the restriction, too.
I think it would be useful and straight forward to implement, I can
include it into v3.

If I understand it correctly, the main difference this would have is
to be able to use spin_locks in a more fine-grained fashion, right?
Meaning, partial reads/updates of the memory area under spin_lock as
opposed to having to lock over the full area? Yeah, sounds like a
reasonable extension to me that could be done on top of the series,
presumably most of the array map logic could also be reused for this
which is nice.
Thanks a lot,
Daniel

Hmm, I actually don't mind too much combining both of them. Had
the same thought with regards to introspection from bpftool which
was why I separated them. But combining the two into a single map
is fine actually, saves a bit of resources in kernel, and offsets
can easily be fixed up from libbpf side. Will do for v3.

Right now the BPF_F_RDONLY, BPF_F_WRONLY semantics to make the
maps read-only or write-only from syscall side are that these
permissions are stored into the struct file front end (file->f_mode)
for the anon inode we use, meaning it's separated from the actual
BPF map, so you can create the map with BPF_F_RDONLY, but root
user can do BPF_MAP_GET_FD_BY_ID without the BPF_F_RDONLY and
again write into it. This design choice would require that we'd
need to add some additional infrastructure on top of this, which
would then need to enforce file->f_mode to read-only after the
first setup. I think there's simple trick we can apply to make
it read-only after setup from syscall side: we'll add a new flag
to the map, and then upon map creation libbpf sets everything
up, holds the id, closes its fd, and refetches the fd by id.
From that point onwards any interface where you would get the
fd from the map in user space will enforce BPF_F_RDONLY behavior
for file->f_mode. Another, less hacky option could be to extend
the struct file ops we currently use for BPF maps and set a
map 'immutable' flag from there which is then enforced once all
pending operations have completed. I can look a bit into this.

My thinking was that these maps are not explicitly user specified,
so libbpf API would expose them through a different interface than
the one we have today in order to not confuse or break application
behavior which would otherwise rely on iterating / processing over
them. Separate API would retain current behavior and definitely
make this unambiguous to apps with regards to what to expect from
each of such API call.

No worries, thanks for all your feedback and review!

The patch version #1 provides a way to replace the load with
immediate (presumably read-only data). This will be good for
the use case like below:
if (static_variable_kernel_version == V1) {
/* code here will work for kernel V1 */
... access helpers available for V1 ...
} else if (static_variable_kernel_version == V2) {
/* code here will work for kernel V2 */
... access helpers available for V2 ...
}
The approach here did not replace the map value access with values from
e.g., readonly section for which libbpf could provide an interface to
fill in data from user.
This may require a little more analysis, e.g.,
ptr = ld_imm64 from a readonly section
...
*(u32 *)ptr;
*(u64 *)(ptr + 8);
...
Do you think we could do this in kernel verifier or we should
push the whole readonly stuff into user space?

Do we plan to pretty-print data/bss with BTF from the bpftool at some
point? Does combining them makes it harder?

I want to point to a subtle difference here between handling pure global
variables and static global variables. The "imm" value is only available
for static variables. For example,
-bash-4.4$ cat g.c
static volatile long sg = 2;
static volatile int si = 3;
long g = 4;
int i = 5;
int test() { return sg + si + g + i; }

You can see the above, the non-static global access does not have its
in-section offset encoded in the insn itself. The difference is due to
llvm treating static global and non-static global differently.
To support both cases, during relocation recording stage, you can
also record:
. symbol binding (GELF_ST_BIND(sym.st_info)),
non-static global has binding STB_GLOBAL and static
global has binding STB_LOCAL
. symbol value (sym.st_value)
During the above relocation resolution, if symbol bind is local, do
what you already did here. If symbol bind is global, assign data_off
with symbol value.
This applied to both .data and .rodata sections.
The non initialized
global variable will not be in any allocated section in ELF file,
it is in a COM section which is to be allocated by loader.
So user defines some like
int g;
and later on uses it. Right now, it will not work. The workaround
is "int g = 4", or "static int g". I guess it should be
okay, we should encourage users to use "static" variables instead.

I thought a bit more about this and I think there is one good reason
(in addition to introspection) to keep them separate.
If total size of .data is not multiple of 8-byte, when appending .bss
to it, we'll need to pad few bytes. It probably would be a good thing
for verifier to enforce that those bytes are never accessed, which
will be impossible to do if we combine .data and .bss.
I'm not sure how important that is, just wanted to bring up one more
counter-argument.

Cool, thanks for explaining!
I think that we can start off without this enforcement, but if we had
this enforcement, it would open up new possibilities for verifier to
optimize/prune code based on values in .rodata, because we'd have
guarantee that values can't change.

Hm... yeah, I guess it's a decision that needs to be made consciously.
To me it feels like global maps are sort of compiler sugar, which
provides good developer experience, but resolves into lower-level
well-known pre-existing abstractions (just another maps). In any case,
more generic tools like bpftool will dump all of them, so I'm not
certain we should treat them as separate concepts in libbpf? We
currently shouldn't be breaking anyone, because applications can't use
static/global data, so these new maps will come up only for new use
cases. If you think it might be important to differentiate between
auto-generated maps and explicitly defined by user maps, then we can
add some bpf_map__{global/special/autogen} accessor to differentiate?
My thinking here is that if you want to iterate all maps, it's kind of
inconvenient to remember to iterate "normal maps" and remember to
generate "automatic maps".
Also, in the future, if libbpf will need to auto-create some other
type of map to support some other features, it will require another
set of APIs to access/iterate them, so it feels like sticking to
single common list is preferrable, imho.

Would it be reasonable to just plain disable usage of uninitialized
global variables, as it kind of goes against BPF's philosophy that
everything should be written to, before can be read? So while we can
just implicitly zero-out everything beforehand, it might be a good
idea to remind and enforce that explictly?

FWIW +1 I think different type is way cleaner here.

We could improve by flagging the error at compiler error or libbpf time.
But it is not required. I am mentioning just for completeness.

I just removed a compiler error for static variables...

Yeah, make sense, BPF_PSEUDO_MAP_VALUE is more explicit.

spin_lock is just a nice bonus, if there is any manipulation that
isn't <= 8 byte long that needs to be done atomically.
The reason for this new type of map is actually ability to update
global variables from outside BPF program in granular fashion. E.g.,
turning on some extra debug output temporarily, tuning parameters,
changing PID to trace, etc, without stopping and reloading BPF
program. With array, it's all-or-nothing: to update anything you have
to overwrite entire .data section. As I mentioned, if we can get BTF
type information for entirety of .data, it would allow to manipulate
those variables by name even with generic tools like bpftool.

And in your case the static_variable_kernel_version would be determined
at runtime, for example, where you then would want to eliminate all the
other branches, right? Meaning, you'd need a way to turn this into a imm
load such that verifier will detect these dead branches and patch them
out, which it should already be able to do. How would you mark these
special vars like static_variable_kernel_version such that they have
special treatment from the rest, some sort of builtin? Potentially one
could get away with doing this from loader side if it's simple enough,
though one thing that would be good to avoid is to duplicate all the
complex branch fixup logic etc that we have in kernel already. Are you
thinking to mark these via BTF in some way such that loader does inline
replacement?
Thanks,
Daniel

Agree and noted, and thanks for pointing this out, Yonghong! I'll
fix this up accordingly in next round.
Thanks a lot,

Yes, agree, I'll add them as well and integrate the correct offset
for libbpf along with it.

By the way, from LLVM side, do you think it makes sense for local vars
where you encode the offset into insn->imm to already encode it into
(insn+1)->imm of the ldimm64, so that loaders can just pass this offset
through instead of fixing it up like I did? I'm fine either way though,
just thought might be worth pointing out while we're at it. :)
Thanks,

Sounds like you'd almost want to mmap the value ;)

Yes, llvm can do that. Let me prototype it and will let you know

Yes, the program will be compiled once and deployed to many hosts with
different kernel versions. Different hosts may have different kernel
versions. The static_variable_kernel_version is determined

A libbpf API is needed to assign a particular value to a readonly
section value. For example, a bpf program may look like:
-bash-4.4$ cat g1.c
static volatile const unsigned __kernel_version;
int prog() {
unsigned kernel_ver = __kernel_version;
if (kernel_ver == 411)
return 0;
else if (kernel_ver == 416)
return 1;
return 2;
}
-bash-4.4$ clang -target bpf -O2 -c g1.c
-bash-4.4$ llvm-readelf -r g1.o
Relocation section '.rel.text' at offset 0x178 contains 1 entries:

The relocation is for the first insn.
The address is the start of .rodata section, which happens to
match variable __kernel_version (size 4).
The libbpf API can provide a way for user to assign a value to readonly
section. In this particular case, e.g., on HostA, __kernel_version is
assigned to 416, which means the first 4 bytes of .rodata is modified
to have value 416. Considering this is a generic interface, the API
may look like
bpf_object__change_readonly_value(const char *var_name, void *val_buf,
unsigned var_buf_size);
The libbpf will change the value if there is a "var_name" in rodata
section and val_buf_size matches the size in the symbol table.

I totally agree that kernel is already able to prune dead codes while
maintaining correct func/line info. We should do that part in kernel.
Let us look at the byte codes,
0000000000000000 prog:
0: r1 = 0 ll
2: r1 = *(u32 *)(r1 + 0)
3: r2 = 1
4: if r1 == 416 goto +1 <LBB0_2>
5: r2 = 2
0000000000000030 LBB0_2:
6: r0 = 0
7: if r1 == 411 goto +1 <LBB0_4>
8: r0 = r2
0000000000000048 LBB0_4:
9: exit
Here, the goal is to let r1 at insn #2 get the constant.
Do you think we can get it from the kernel? In this particular case,
insn #0, get a romap_ptr with addr of rodata section offset 0,
insn #2, load u32 from romap offset 0, the value is already populated,
e.g., 416.
The verifier is path sensitive, will need extra care to
perform such transformation in case it is invalid in different paths.
Maybe slightly extension of verifier is able to do this?
Initially we do not need to handle complicated cases. Most global/static
variable accesses are all like
r1 = #num ll
r1 = *(type *)(r1 + offset)
If there is branch into the middle of the above pair of insns
and r1 is romap_ptr, it is totally safe to replace the second insn
as r1 = constant which can enable later dead code elimination.
If all read only region access are converted to constants,
"r1 = #num ll" ld_imm64 insns can be removed as well.

I have not thought about BTF. BTF could provide information about insn
#2 referring to a particular readonly section location. But looks like
verifier is able to track it as well in the above?
Let us first study whether without BTF is okay. If needed, we can go
through BTF path with compiler assistance.

Note the map_name field only 16 bytes (excluding ending '\0', only 15
bytes). If <obj> file has a long name like test_verifier.o, you may have
to shorten the <obj> part of the name.

Yes, it needs to be ensured that (bss/)data/rodata part is still visible
to the user, so <obj> part would need to be truncated accordingly.

Next line after this one rejects ldimm64 instructions with off != 0.
This check needs to be changed, depending on whether src_reg ==
BPF_PSEUDO_MAP_VALUE, right?
This is also to the previously discussed question of not enforcing
offset (imm=0 in 2nd part of insn) for BPF_PSEUDO_MAP_FD. Seems like
verifier *does* enforce that (not that I'm advocating for re-using
BPF_PSEUDO_MAP_FD, just stumbled on this bit when going through
verifier code).

FYI, we noticed the following commit (built with gcc-8):
commit: 4beb1a5f45dc210b1dcccadaf77cfdd454b4b170 ("[PATCH bpf-next v2 6/7] bpf, selftest: test global data/bss/rodata sections")
url: https://github.com/0day-ci/linux/commits/Daniel-Borkmann/BPF-support-for-global-data/20190301-112203
base: https://git.kernel.org/cgit/linux/kernel/git/bpf/bpf-next.git master
in testcase: kernel_selftests
with following parameters:

Yes, that's correct, I already have that changed in my local branch for
supporting non-zero off.

Not really, lets test:
[...]
.insns = {
BPF_MOV64_IMM(BPF_REG_0, 0),
BPF_RAW_INSN(BPF_LD | BPF_IMM | BPF_DW, BPF_REG_1,
BPF_PSEUDO_MAP_FD, 0, 0),
BPF_RAW_INSN(0, 0, 0, 0, 0xfefefe),
BPF_EXIT_INSN(),
},
[...]
#545/p test14 ld_imm64: reject 2nd imm != 0 FAIL
Unexpected success to load!
0: (b7) r0 = 0
1: (18) r1 = 0xffff97e612486400
3: (95) exit
processed 3 insns (limit 131072), stack depth 0
Summary: 0 PASSED, 0 SKIPPED, 2 FAILED
So I still think it would be worth doing something like the below
for bpf:

Subject: [PATCH bpf] bpf: fix replace_map_fd_with_map_ptr wrt ldimm64 wrt second imm field
Non-zero imm value in the second part of the ldimm64 instruction for
BPF_PSEUDO_MAP_FD is invalid, and thus must be rejected. The map fd
only ever sits in the first instructions' imm field. None of the BPF
loaders known to us are using it, so risk of regression is minimal.
For clarity and consistency, the few insn->{src_reg,imm} occurences
are rewritten into insn[0].{src_reg,imm}. Add a test case to the BPF
selftest suite as well.
Fixes: 0246e64d9a5f ("bpf: handle pseudo BPF_LD_IMM64 insn")

Ah, sorry, my bad. That code tests .off, not .imm, so yeah, any imm

Thanks a lot for working on it.

1.
typical ldimm64 carries 64-bit value. upper 32-bits are in insn[1]->imm.
I think it's better to stick to this meaning of imm for encoding
the section offset and keep it in insn[0]->imm.
Especially since from disassembler pov it looks like normal ldimm64 with relocation.
Later libbpf does PSEUDO trick and can move [0]->imm to [1]->imm.
Or it can use [1]->imm to store FD to pass to kernel?
Another alternative is to use 16-bit of 'off' to encode the offset,
but the limit of 32kbyte of static variables is probably too small.
2.
I think it's better to only allow 'static int foo' in libbpf for now.
In C 'global' variables suppose to be shareable across multiple elf files.
libbpf doesn't have support for it yet. We need to start discussing this multi elf
support which will lead into discussion about bpf libraries.
I think we need a bit of freedom to decide the meaning of 'global' modifier.
So for now I would support only 'static int foo' in libbpf.
llvm supports both and that's ok, since that's a standard elf markings.
Also were these patches tested with 'static struct {int a; int b;} foo;' and
'static char foo[]="my string";' ?
I suspect it should 'just work' with proposed design, but would be good to have a test.
3.
let's come up with concrete plan for BTF for these static variables.
With normal maps the BTF was retrofitted via BPF_ANNOTATE_KV_PAIR macro
and no one is proud of this interface choice. We had 'struct bpf_map_def'
and the macro was the least evil.
For static variables let's figure out how to integrate BTF into it cleanly.
LLVM already knows about the types. It needs another kind to describe
the variable names and offsets. I think what we did with BTF_KIND_FUNC
should be applicable here. Last time we discussed that we will add BTF_KIND_VAR
for this purpose. Shouldn't be too much work to hack it into llvm now?
I would even go a step further and make BTF to be mandatory for static vars.
Introspection of BPF programs will go long way.
4.
if we make BTF mandatory then the issue of map names will be solved too.
The <obj>.bss/data/rodata might not fit into map_name[16],
but with BTF we can give it full name.
"<obj>.data" looks great to me especially from introspection angle.
5.
I think it makes sense to keep .bss vs .data vs .rodata separate.
I can imagine a program using large zero-inited static array.
It's important to save space in elf file, save time to do map create
and map populate. With combined .data and .bss it would be much harder.
6.
as the next step would be good to add two new syscall command to read/write
individual static variables. Something like:
bpf_map_read/write_bytes(map, key, offset_in_value, buf, size_of_buf)
would allow user space to tweak certain variables.
With mandatory BTF we can have an api to read/write variable by name
(and not only by offset).
Such bpf_map_read_bytes() would be useful for regular hash maps too.
It's convenient to be able to update few bytes in the hash value instead
of overwriting the whole thing.
7.
since these 3 maps are created as normal arrays from kernel pov
the 'bpftool map show' should not exclude them from the output.
Similarly libbpf api bpf_object__for_each_map() and bpf_map__next()
should probably include them too. There can be bpf_map__is_pseudo() flag
to tell them apart, but since it's a normal map in the kernel
other libbpf accessors bpf_map__name(), bpf_map__pin() should work too.

Hadn't thought about it from this angle, but yes, from debugging /disasm
point of view it makes perfect sense to keep it as-is.

My preference would rather be the former as it's consistent with how
we do it for normal map fds as well, so I'd keep loader side having it
moved as it currently is; I think it's fine.

Yes agree, and I've also reused both off fields now for optionally
allowing to select an index into the array based on Andrii's feedback.

Makes sense, we first need to have a better understanding on how semantics
should look there from BPF pov. I'll restrict libbpf for static vars for
the time being, and throw an error message otherwise.
There is one more semantical question: a BPF ELF file can have multiple
program entry points in it. Both programs from there could refer to static
global variables inside that object file. My thinking which this patch set
also implemented is to have both of them refer to the same .bss/.data/.rodata
map (and _not_ separate ones) as I think this would also naturally be what
the user is expecting when referring to the same global vars in the given
object file.

+1, I'll add more tests. Iirc, I tested it back with the original prototype
from LPC which worked same way from high level point of view, but good to
have it explicitly in BPF selftests, agree, will add.

We can make that mandatory, nice thing would be that such BPF_ANNOTATE_KV_PAIR
macro hack wouldn't be needed at all. From BTF pov, that would be some sort of
BTF_KIND_SEC as a section 'container' for all BTF_KIND_VAR variables belonging
to it, so map could use its id to describe its map value as such?

I'm fine either way, but yeah, this approach as also taken here means less
fixing up from loader pov, and it would probably also make BTF handling
easier. So, sticking with separate .bss/.data/.rodata then.

Definitely useful, there was also the suggestion to have an mmap interface
which would work at least for array maps, though haven't looked yet into
what would be needed from buffer mgmt side to remap for processes that just
got the fd by id or via bpf fs for retrieving existing content.

Yeah, I'll integrate it there in libbpf, as long as we have something to
tell them apart from a user pov it should be good.
