[PATCH 00/15] fix packing of structs when building with MSVC

[Tyler Retzlaff]

MSVC struct packing is not compatible with GCC provide a macro that can
be used to push existing pack value and sets packing to 1-byte. The
existing __rte_packed macro is then used to restore the pack value
prior to the push.

Instead of providing macros exclusively for MSVC and for GCC the
existing macro is deliberately utilized to trigger a warning if no
existing packing has been pushed allowing easy identification of
locations where the __rte_msvc_pack is missing.

I've decided to only add the macro to packed structs that are built
for Windows. It seems there is little value in adding the macro tree
wide and if new code arrives that is built on Windows the __rte_packed
will flag where the preamble macro is required.

This struct almost certainly doesn't need to be packed - since it's in a
private header, I would imagine removing packing wouldn't be an ABI
break.
Also, removing rte_packed doesn't change the size for me for a 64-bit x86
build. Looking at the struct, I don't see why it would change on a 32-bit
build either.

This also doesn't look like it should be packed. It is a public header
though so we may need to be more careful. Checking a 64-bit x86 build shows
no size change when removing the "packed" attribute, though. For 32-bit, I
think the "size_t" field in the middle would be followed by padding on
32-bit if we removed the "packed" attribute, so it may be a no-go for now.
:-(

From code review, this doesn't look like "packed" has any impact, since all
fields should naturally be aligned on both 32-bit and 64-bit builds.

This struct has all gaps explicitly filled, so packed should not be
necessary. Struct has same size with and without the attribute.

just eyeballing it i think

        uint32_t        dmacapability;  /* 0x10 */

with packing will not be aligned on a 4-byte boundary.

maybe i miscounted though.

Looking at the structure, I believe only the inner packed attribute is
necessary. However, given that we need packed attributes, for safety, let's
keep them both.

This is exactly 16-bytes in size, with all members explicitly sized and
properly aligned. Therefore we can drop the packed atttribute.

Two 16-bit fields only, so no need to pack this struct either.

Should not need to be packed, as no padding.

However, if we don't mark this as packed could we hit problems if (for
whatever reason) we ever receive a packet where the gre_hdr is not aligned
on an even byte boundary? Does packing affect the minimum alignment
requirements of the whole struct, as well as removing padding?

These structs don't look to me like they need packing. No padding should
appear between elements of the structs. The last struct definitely doesn't
need it, as it's a uint8_t array.

Why is packed used so many places in DPDK?
Packed should be reserved for things like network protocols
with unaligned fields.

Many of these structure have no holes and are naturally packed.
Adding packed attribute unnecessarily can generate poor code on
architectures that do not support unaligned access.

I made the same observation. Even network frame formats can be handled
without packing so long as you do some extra work to copy small units
of data out which is often worth doing manually and once only instead
of obfuscated behind codegen and direct field access.

For the specific case where their fields and alignments are naturally
packed I'm not entirely certain you get different codegen but I agree
it might and we'd like to avoid it if it does.

In a lot of the cases it seems to be drivers and often appears like it
is either structs that are used to hardware registers or firmware
protocol data units. Both of which may be need packing.

I will commit to removing packing in structs in this series iff
individual maintainers identify the specific structs in reply to the
series.  If there is no request I'll leave it to them to figure out.

Maintainers should review and request removal as appropriate.

Thanks!

[PATCH v2 00/15] fix packing of structs when building with MSVC

[Tyler Retzlaff]

MSVC struct packing is not compatible with GCC provide a macro that can
be used to push existing pack value and sets packing to 1-byte. The
existing __rte_packed macro is then used to restore the pack value
prior to the push.

Instead of providing macros exclusively for MSVC and for GCC the
existing macro is deliberately utilized to trigger a warning if no
existing packing has been pushed allowing easy identification of
locations where the __rte_msvc_pack is missing.

I've decided to only add the macro to packed structs that are built
for Windows. It seems there is little value in adding the macro tree
wide and if new code arrives that is built on Windows the __rte_packed
will flag where the preamble macro is required.

If as a part of review maintainers identify structs they believe
don't require packing so long as they are explicitly identified
i'll remove the __rte_packed as a part of this series.

v2:
  * app/testpmd, remove packing from simple_gre_hdr
  * net/iavf, remove packing from iavf_ipsec_crypto_pkt_metadata,

[PATCH v2 01/15] eal: provide pack start macro for MSVC

[Tyler Retzlaff]

MSVC struct packing is not compatible with GCC provide a macro that can
be used to push existing pack value and sets packing to 1-byte. The
existing __rte_packed macro is then used to restore the pack value
prior to the push.

Instead of providing macros exclusively for MSVC and for GCC the
existing macro is deliberately utilized to trigger a warning if no
existing packing has been pushed allowing easy identification of
locations where the __rte_msvc_pack is missing.

[PATCH v2 02/15] eal: pack structures when building with MSVC

[Tyler Retzlaff]

Add __rte_msvc_pack to all __rte_packed structs to cause packing
when building with MSVC.

Remove __rte_packed where it appears natural alignment without
packing would produce the same layout or the struct is internal.

Remove __rte_packed where it appears natural alignment without

[PATCH v3 00/16] fix packing of structs when building with MSVC

[Tyler Retzlaff]

MSVC struct packing is not compatible with GCC provide a macro that can
be used to push existing pack value and sets packing to 1-byte. The
existing __rte_packed macro is then used to restore the pack value
prior to the push.

Instead of providing macros exclusively for MSVC and for GCC the
existing macro is deliberately utilized to trigger a warning if no
existing packing has been pushed allowing easy identification of
locations where the __rte_msvc_pack is missing.

I've decided to only add the macro to packed structs that are built
for Windows. It seems there is little value in adding the macro tree
wide and if new code arrives that is built on Windows the __rte_packed
will flag where the preamble macro is required.

If as a part of review maintainers identify structs they believe
don't require packing so long as they are explicitly identified
i'll remove the __rte_packed as a part of this series.

v3:
  * add missing __rte_msvc_pack to crypto/mlx5
  * fix commit messages to reference __rte_msvc_pack macro instead
    of __rte_msvc_pushpack(1)

v2:
  * app/testpmd, remove packing from simple_gre_hdr
  * net/iavf, remove packing from iavf_ipsec_crypto_pkt_metadata,
    simple_gre_hdr
  * examples, remove packing from pkt_key_qinq, pkt_key_ipv4_5tuple,
    pkt_key_ipv6_5tuple, pkt_key_ipv4_addr, pkt_key_ipv6_addr
  * eal, remove packing from rte_config, __rte_trace_stream_header

[PATCH v3 01/16] eal: provide pack start macro for MSVC

[Tyler Retzlaff]

MSVC struct packing is not compatible with GCC provide a macro that can
be used to push existing pack value and sets packing to 1-byte. The
existing __rte_packed macro is then used to restore the pack value
prior to the push.

Instead of providing macros exclusively for MSVC and for GCC the
existing macro is deliberately utilized to trigger a warning if no
existing packing has been pushed allowing easy identification of
locations where the __rte_msvc_pack is missing.

[PATCH v3 02/16] eal: pack structures when building with MSVC

[Tyler Retzlaff]

Add __rte_msvc_pack to all __rte_packed structs to cause packing
when building with MSVC.

Remove __rte_packed where it appears natural alignment without
packing would produce the same layout or the struct is internal.

Remove __rte_packed where it appears natural alignment without
packing would produce the same layout or the struct is internal.

[PATCH v4 00/16] fix packing of structs when building with MSVC

[Tyler Retzlaff]

MSVC struct packing is not compatible with GCC provide a macro that can
be used to push existing pack value and sets packing to 1-byte. The
existing __rte_packed macro is then used to restore the pack value
prior to the push.

Instead of providing macros exclusively for MSVC and for GCC the
existing macro is deliberately utilized to trigger a warning if no
existing packing has been pushed allowing easy identification of
locations where the __rte_msvc_pack is missing.

I've decided to only add the macro to packed structs that are built
for Windows. It seems there is little value in adding the macro tree
wide and if new code arrives that is built on Windows the __rte_packed
will flag where the preamble macro is required.

If as a part of review maintainers identify structs they believe
don't require packing so long as they are explicitly identified
i'll remove the __rte_packed as a part of this series.

v4:
  * add another missing __rte_msvc_pack to crypto/mlx5 patch
  * correct commit message for duplicated packing packing in
    crypto/mlx5 patch

v3:
  * add missing __rte_msvc_pack to crypto/mlx5
  * fix commit messages to reference __rte_msvc_pack macro instead
    of __rte_msvc_pushpack(1)

v2:
  * app/testpmd, remove packing from simple_gre_hdr
  * net/iavf, remove packing from iavf_ipsec_crypto_pkt_metadata,
    simple_gre_hdr
  * examples, remove packing from pkt_key_qinq, pkt_key_ipv4_5tuple,
    pkt_key_ipv6_5tuple, pkt_key_ipv4_addr, pkt_key_ipv6_addr
  * eal, remove packing from rte_config, __rte_trace_stream_header

[PATCH v4 01/16] eal: provide pack start macro for MSVC

[Tyler Retzlaff]

MSVC struct packing is not compatible with GCC provide a macro that can
be used to push existing pack value and sets packing to 1-byte. The
existing __rte_packed macro is then used to restore the pack value
prior to the push.

Instead of providing macros exclusively for MSVC and for GCC the
existing macro is deliberately utilized to trigger a warning if no
existing packing has been pushed allowing easy identification of
locations where the __rte_msvc_pack is missing.

[PATCH v4 02/16] eal: pack structures when building with MSVC

[Tyler Retzlaff]

Add __rte_msvc_pack to all __rte_packed structs to cause packing
when building with MSVC.

Remove __rte_packed where it appears natural alignment without
packing would produce the same layout or the struct is internal.

Remove __rte_packed where it appears natural alignment without
packing would produce the same layout or the struct is internal.

[PATCH v5 00/16] fix packing of structs when building with MSVC

[Andre Muezerie]

From: Andre Muezerie <andremue@ntdev.microsoft.com>

MSVC struct packing is not compatible with GCC provide a macro that can
be used to push existing pack value and sets packing to 1-byte. The
existing __rte_packed macro is then used to restore the pack value
prior to the push.

Instead of providing macros exclusively for MSVC and for GCC the
existing macro is deliberately utilized to trigger a warning if no
existing packing has been pushed allowing easy identification of
locations where the __rte_msvc_pack is missing.

I've decided to only add the macro to packed structs that are built
for Windows. It seems there is little value in adding the macro tree
wide and if new code arrives that is built on Windows the __rte_packed
will flag where the preamble macro is required.

If as a part of review maintainers identify structs they believe
don't require packing so long as they are explicitly identified
i'll remove the __rte_packed as a part of this series.

v5:
  * rebase on top of latest main

v4:
  * add another missing __rte_msvc_pack to crypto/mlx5 patch
  * correct commit message for duplicated packing packing in
    crypto/mlx5 patch

v3:
  * add missing __rte_msvc_pack to crypto/mlx5
  * fix commit messages to reference __rte_msvc_pack macro instead
    of __rte_msvc_pushpack(1)

v2:
  * app/testpmd, remove packing from simple_gre_hdr
  * net/iavf, remove packing from iavf_ipsec_crypto_pkt_metadata,
    simple_gre_hdr
  * examples, remove packing from pkt_key_qinq, pkt_key_ipv4_5tuple,
    pkt_key_ipv6_5tuple, pkt_key_ipv4_addr, pkt_key_ipv6_addr
  * eal, remove packing from rte_config, __rte_trace_stream_header

[PATCH v5 01/16] eal: provide pack start macro for MSVC

[Andre Muezerie]

From: Tyler Retzlaff <roretzla@linux.microsoft.com>

MSVC struct packing is not compatible with GCC. Provide a macro that
can be used to push existing pack value and sets packing to 1-byte.
The existing __rte_packed macro is then used to restore the pack value
prior to the push.

Instead of providing macros exclusively for MSVC and for GCC the
existing macro is deliberately utilized to trigger a warning if no
existing packing has been pushed allowing easy identification of
locations where the __rte_msvc_pack is missing.

Before proceeding with this, can we please discuss the alternative, proposed here:
https://inbox.dpdk.org/dev/CAJFAV8yStgiBbe+Nkt9mC30r0+ZP64_kGuRHOzqd90RD2HXZyw@mail.gmail.com/

The definition of the packing macro in OVS, for reference:
https://github.com/openvswitch/ovs/blob/main/include/openvswitch/compiler.h#L209

The current solution requires __rte_packed to be placed at the end of a structure, although __attribute__((packed)) is normally allowed at the beginning (between the "struct" tag and the name of the structure), which introduces a high risk of contributors placing it "incorrectly", thus causing errors.

I have a strong preference for an __RTE_PACKED(decl) variant.

Here's a third alternative:
#ifdef RTE_TOOLCHAIN_MSVC
#define __rte_msvc_pack_begin __pragma(pack(push, 1))
#define __rte_msvc_pack_end   __pragma(pack(pop))
#else
#define __rte_msvc_pack_begin
#define __rte_msvc_pack_end
#endif

The third alternative is also problematic, e.g. if a contributor forgets the _end after the structure declaration, or adds another structure declaration before the _end.

Yes, that one looks much nicer to me too.
Could I also ask to avoid creeping _msvc_ into DPDK namespace.

These are all good comments. I'll look more into it.

I looked at the suggestions made and I liked the one having a __RTE_PACKED macro
the most.

Advantages:
- Can be placed in front of the struct, or even in the middle. Good for readability.
- Does not require a different macro to be placed at the end of the structure as was
  proposed in V5 series.
- Works well in 99% of the cases.

Problems can arise when compiler directives are present in the struct, as they
become arguments for __RTE_PACKED macro. This is not portable.
I've seen two situations in the DPDK code:

1) #defines mentioned in the struct. In this situation we can just move the
   #define out of the struct.

2) #if/#ifdef/#elif mentioned in the struct.
This is a somewhat common pattern in structs where fields change based on
endianness.
Example:

/**
 * IPv4 Header
 */
struct __rte_aligned(2) rte_ipv4_hdr {
	__extension__
	union {
		uint8_t version_ihl;    /**< version and header length */
		struct {
#if RTE_BYTE_ORDER == RTE_LITTLE_ENDIAN
			uint8_t ihl:4;     /**< header length */
			uint8_t version:4; /**< version */
#elif RTE_BYTE_ORDER == RTE_BIG_ENDIAN
			uint8_t version:4; /**< version */
			uint8_t ihl:4;     /**< header length */
#endif
		};
	};
	uint8_t  type_of_service;	/**< type of service */
	rte_be16_t total_length;	/**< length of packet */
...
} __rte_packed;

One way to solve this is to move the #if to the outside. But that involves
defining the struct twice (once for each endianness). It's less than
ideal because common parts would be duplicated. I'm not sure how popular
this would be.
It's not so common though (about 1% of the structs?). I think it's an
acceptable trade-off to get portable code, but I would like to hear your
thoughts.

Result after moving #if to the outside of the struct:

#if RTE_BYTE_ORDER == RTE_LITTLE_ENDIAN
__RTE_PACKED(
struct __rte_aligned(2) rte_ipv4_hdr {
	__extension__
	union {
		uint8_t version_ihl;    /**< version and header length */
		struct {
			uint8_t ihl:4;     /**< header length */
			uint8_t version:4; /**< version */
		};
	};
	uint8_t  type_of_service;	/**< type of service */
	rte_be16_t total_length;	/**< length of packet */
...
});
#elif RTE_BYTE_ORDER == RTE_BIG_ENDIAN
__RTE_PACKED(
struct __rte_aligned(2) rte_ipv4_hdr {
	__extension__
	union {
		uint8_t version_ihl;    /**< version and header length */
		struct {
			uint8_t version:4; /**< version */
			uint8_t ihl:4;     /**< header length */
#endif
		};
	};
	uint8_t  type_of_service;	/**< type of service */
	rte_be16_t total_length;	/**< length of packet */
...
});
#endif

This code would be portable if Microsoft would align with other compilers.

Also I'm not sure we really need __rte_packed for most network protocols.

Indeed, it's is a shame that the way MSVC works differs so much, but
unfortunately that won't change.

Considering the implications of the __RTE_PACK macro approach on these
special cases, perhaps the initial proposal made in the series that was
submitted for review is better after all? At least it does not have
these "special" cases, so the approach required on the code would be
uniform in the entire code base.

Good catch.
Although it is relatively rare, it is a standard design pattern, also in other projects than DPDK. We should either support it, or emit an error on occurrence when compiling.

Many network protocol structures contain uint32_t/rte_be32_t fields, which makes the structures 4-byte aligned; but the preceding 14 byte Ethernet header makes them non-4-byte aligned. So their alignment needs to be reduced from 4-byte to 2-byte.

Agree.
If we don't like "msvc" in the macro name, we could rename __rte_msvc_pack to __rte_packed_begin.
We could also rename __rte_packed to __rte_packed_end, emphasizing that __rte_packed is no longer allowed at the beginning of structures.
And for backwards compatibility add #define __rte_packed __rte_packed_end.

Structures would then look like this:

struct __rte_packed_begin __rte_aligned(2) rte_proto_hdr {
	rte_be32_t	proto_field;
...
} __rte_packed_end;

If you prefer keeping __rte_packed instead of renaming it to __rte_packed_end, it would probably be easy for checkpatch to verify its location in the structure declaration, as it must always be directly preceded by whitespace and directly followed by a semicolon.
(The same goes for __rte_packed_end.)

Checkpatch could also verify that each __rte_packed_end/__rte_packed is preceded by __rte_packed_begin, for MSVC compatibility.

Makes sense. I'll update the series accordingly.

so just some additional info here.

for the compiler that cares about the end (i.e. msvc) msvc actually
emits a warning (treated as error) if a push pack is not closed with a
pop pack within a header or a tu. that's one of the benefits of the
macros in original proposal.

[PATCH v5 02/16] eal: pack structures when building with MSVC

[Andre Muezerie]

From: Tyler Retzlaff <roretzla@linux.microsoft.com>

Add __rte_msvc_pack to all __rte_packed structs to cause packing
when building with MSVC.

Remove __rte_packed where it appears natural alignment without
packing would produce the same layout or the struct is internal.

[PATCH v5 09/16] net/iavf: pack structures when building with MSVC

[Andre Muezerie]

From: Tyler Retzlaff <roretzla@linux.microsoft.com>

Add __rte_msvc_pack to all __rte_packed structs to cause packing
when building with MSVC.

Remove __rte_packed where it appears natural alignment without
packing would produce the same layout or the struct is internal.

[PATCH v5 16/16] crypto/mlx5: pack structures when building with MSVC

[Andre Muezerie]

From: Tyler Retzlaff <roretzla@linux.microsoft.com>

Add __rte_msvc_pack to all __rte_packed structs to cause packing
when building with MSVC.

[PATCH v6 00/30] fix packing of structs when building with MSVC

[Andre Muezerie]

MSVC struct packing is not compatible with GCC. Provide a macro
(__rte_packed_begin) that can be used to push existing pack value
and sets packing to 1-byte. The existing __rte_packed macro is
replaced with __rte_packed_end and restores the pack value
prior to the push.

Instead of providing macros exclusively for MSVC and for GCC,
macro __rte_packed_end is deliberately utilized to trigger a
MSVC compiler warning if no existing packing has been pushed allowing
easy identification of locations where the __rte_packed_begin is
missing.

Macro __rte_packed is removed and the two new macros represent the
new way to enable packing in the DPDK code.

Script checkpatches.sh was enhanced to ensure __rte_packed_begin and
__rte_packed_end show up in pairs when checking patches.

If as a part of review maintainers identify structs they believe
don't require packing so long as they are explicitly identified
I'll remove the __rte_packed as a part of this series.

v6:
  * replace __rte_msvc_pack with __rte_packed_begin
  * replace __rte_packed with __rte_packed_end
  * update checkpatches.sh to ensure __rte_packed_begin and
    __rte_packed_end are used in pairs
  * remove __rte_packed

v5:
  * rebase on top of latest main

v4:
  * add another missing __rte_msvc_pack to crypto/mlx5 patch
  * correct commit message for duplicated packing packing in
    crypto/mlx5 patch

v3:
  * add missing __rte_msvc_pack to crypto/mlx5
  * fix commit messages to reference __rte_msvc_pack macro instead
    of __rte_msvc_pushpack(1)

v2:
  * app/testpmd, remove packing from simple_gre_hdr
  * net/iavf, remove packing from iavf_ipsec_crypto_pkt_metadata,
    simple_gre_hdr
  * examples, remove packing from pkt_key_qinq, pkt_key_ipv4_5tuple,
    pkt_key_ipv6_5tuple, pkt_key_ipv4_addr, pkt_key_ipv6_addr
  * eal, remove packing from rte_config, __rte_trace_stream_header

[PATCH v6 02/30] eal/include: add new packing macros

[Andre Muezerie]

MSVC struct packing is not compatible with GCC. Add macro
__rte_packed_begin which can be used to push existing pack value
and set packing to 1-byte. Add macro __rte_packed_end to restore
the pack value prior to the push.

Macro __rte_packed_end is deliberately utilized to trigger a
MSVC compiler warning if no existing packing has been pushed allowing
easy identification of locations where the __rte_packed_begin is
missing.

Macro __rte_packed will be removed in a subsequent patch.

[PATCH v6 07/30] drivers/bus: replace packed attributes

[Andre Muezerie]

MSVC struct packing is not compatible with GCC. Replace macro
__rte_packed with __rte_packed_begin to push existing pack value
and set packing to 1-byte and macro __rte_packed_end to restore
the pack value prior to the push.

Macro __rte_packed_end is deliberately utilized to trigger a
MSVC compiler warning if no existing packing has been pushed allowing
easy identification of locations where the __rte_packed_begin is
missing.

[PATCH v6 08/30] drivers/common: replace packed attributes

[Andre Muezerie]

MSVC struct packing is not compatible with GCC. Replace macro
__rte_packed with __rte_packed_begin to push existing pack value
and set packing to 1-byte and macro __rte_packed_end to restore
the pack value prior to the push.

Macro __rte_packed_end is deliberately utilized to trigger a
MSVC compiler warning if no existing packing has been pushed allowing
easy identification of locations where the __rte_packed_begin is
missing.

[PATCH v6 09/30] drivers/compress: replace packed attributes

[Andre Muezerie]

MSVC struct packing is not compatible with GCC. Replace macro
__rte_packed with __rte_packed_begin to push existing pack value
and set packing to 1-byte and macro __rte_packed_end to restore
the pack value prior to the push.

Macro __rte_packed_end is deliberately utilized to trigger a
MSVC compiler warning if no existing packing has been pushed allowing
easy identification of locations where the __rte_packed_begin is
missing.

MSVC struct packing is not compatible with GCC. Replace macro
__rte_packed with __rte_packed_begin to push existing pack value
and set packing to 1-byte and macro __rte_packed_end to restore
the pack value prior to the push.

Macro __rte_packed_end is deliberately utilized to trigger a
MSVC compiler warning if no existing packing has been pushed allowing
easy identification of locations where the __rte_packed_begin is
missing.

[PATCH v6 11/30] drivers/dma: replace packed attributes

[Andre Muezerie]

MSVC struct packing is not compatible with GCC. Replace macro
__rte_packed with __rte_packed_begin to push existing pack value
and set packing to 1-byte and macro __rte_packed_end to restore
the pack value prior to the push.

Macro __rte_packed_end is deliberately utilized to trigger a
MSVC compiler warning if no existing packing has been pushed allowing
easy identification of locations where the __rte_packed_begin is
missing.

[PATCH v6 14/30] drivers/net: replace packed attributes

[Andre Muezerie]

MSVC struct packing is not compatible with GCC. Replace macro
__rte_packed with __rte_packed_begin to push existing pack value
and set packing to 1-byte and macro __rte_packed_end to restore
the pack value prior to the push.

Macro __rte_packed_end is deliberately utilized to trigger a
MSVC compiler warning if no existing packing has been pushed allowing
easy identification of locations where the __rte_packed_begin is
missing.

[PATCH v6 15/30] drivers/raw: replace packed attributes

[Andre Muezerie]

MSVC struct packing is not compatible with GCC. Replace macro
__rte_packed with __rte_packed_begin to push existing pack value
and set packing to 1-byte and macro __rte_packed_end to restore
the pack value prior to the push.

Macro __rte_packed_end is deliberately utilized to trigger a
MSVC compiler warning if no existing packing has been pushed allowing
easy identification of locations where the __rte_packed_begin is
missing.

MSVC struct packing is not compatible with GCC. Replace macro
__rte_packed with __rte_packed_begin to push existing pack value
and set packing to 1-byte and macro __rte_packed_end to restore
the pack value prior to the push.

Macro __rte_packed_end is deliberately utilized to trigger a
MSVC compiler warning if no existing packing has been pushed allowing
easy identification of locations where the __rte_packed_begin is
missing.

Added parenthesis around *pnum in line
__ rte_packed_end (*pnum) = (void *)pn;
to avoid patch check error below:

[PATCH v6 20/30] examples/ipsec_secgw: replace packed attributes

[Andre Muezerie]

MSVC struct packing is not compatible with GCC. Replace macro
__rte_packed with __rte_packed_begin to push existing pack value
and set packing to 1-byte and macro __rte_packed_end to restore
the pack value prior to the push.

Macro __rte_packed_end is deliberately utilized to trigger a
MSVC compiler warning if no existing packing has been pushed allowing
easy identification of locations where the __rte_packed_begin is
missing.

[PATCH v6 28/30] lib/pipeline: replace packed attributes

[Andre Muezerie]

MSVC struct packing is not compatible with GCC. Replace macro
__rte_packed with __rte_packed_begin to push existing pack value
and set packing to 1-byte and macro __rte_packed_end to restore
the pack value prior to the push.

Macro __rte_packed_end is deliberately utilized to trigger a
MSVC compiler warning if no existing packing has been pushed allowing
easy identification of locations where the __rte_packed_begin is
missing.

Remove macro __rte_packed now that the code was made portable using
__rte_packed_begin to push existing pack value
and set packing to 1-byte and macro __rte_packed_end to restore
the pack value prior to the push when MSVC is used.

I had mentionned this in a separate thread.
Why not do like OVS and have a RTE_PACKED() macro?

#ifdef RTE_TOOLCHAIN_MSVC
#define RTE_PACKED(...) __pragma(pack(push, 1)) __VA_ARGS__ __pragma(pack(pop))
#else
#define RTE_PACKED(...) __VA_ARGS__ __attribute__((__packed__))
#endif

This removes the need for updating checkpatch.
Plus, builds on Linux will catch issues (hopefully by the author of
the change, before submitting).


>   * remove __rte_packed

Please mark it deprecated for now (see RTE_DEPRECATED / add a
deprecation notice) and we will remove it in 25.11.

Mm, in practice, this would be problematic with struct where
endianness matters (for example).

[PATCH v7 00/29] fix packing of structs when building with MSVC

[Andre Muezerie]

MSVC struct packing is not compatible with GCC. Provide a macro
(__rte_packed_begin) that can be used to push existing pack value
and sets packing to 1-byte. The existing __rte_packed macro is
replaced with __rte_packed_end and restores the pack value
prior to the push.

Instead of providing macros exclusively for MSVC and for GCC,
macro __rte_packed_end is deliberately utilized to trigger a
MSVC compiler warning if no existing packing has been pushed allowing
easy identification of locations where the __rte_packed_begin is
missing.

Macro __rte_packed is removed and the two new macros represent the
new way to enable packing in the DPDK code.

Script checkpatches.sh was enhanced to ensure __rte_packed_begin and
__rte_packed_end show up in pairs when checking patches.

If as a part of review maintainers identify structs they believe
don't require packing so long as they are explicitly identified
I'll remove the __rte_packed as a part of this series.

v7:
  * added __rte_packed back but marked it deprecated

v6:
  * replace __rte_msvc_pack with __rte_packed_begin
  * replace __rte_packed with __rte_packed_end
  * update checkpatches.sh to ensure __rte_packed_begin and
    __rte_packed_end are used in pairs
  * remove __rte_packed

v5:
  * rebase on top of latest main

v4:
  * add another missing __rte_msvc_pack to crypto/mlx5 patch
  * correct commit message for duplicated packing in
    crypto/mlx5 patch

v3:
  * add missing __rte_msvc_pack to crypto/mlx5
  * fix commit messages to reference __rte_msvc_pack macro instead
    of __rte_msvc_pushpack(1)

v2:
  * app/testpmd, remove packing from simple_gre_hdr
  * net/iavf, remove packing from iavf_ipsec_crypto_pkt_metadata,
    simple_gre_hdr
  * examples, remove packing from pkt_key_qinq, pkt_key_ipv4_5tuple,
    pkt_key_ipv6_5tuple, pkt_key_ipv4_addr, pkt_key_ipv6_addr
  * eal, remove packing from rte_config, __rte_trace_stream_header

With GCC, __rte_packed could also be used with enums [1], to reduce their size.

The release notes coming with this patch series should mention that this is no longer possible.

Suggest that this script also checks that __rte_packed_begin is not preceded by "enum" (and whitespace).
(A structure packed with __rte_packed_begin might also be __rte_aligned(), and these two attributes may come in any order, so checking for "struct"+whitespace would introduce an ordering requirement for these two attributes.)

[PATCH v7 02/29] eal/include: add new packing macros

[Andre Muezerie]

MSVC struct packing is not compatible with GCC. Add macro
__rte_packed_begin which can be used to push existing pack value
and set packing to 1-byte. Add macro __rte_packed_end to restore
the pack value prior to the push.

Macro __rte_packed_end is deliberately utilized to trigger a
MSVC compiler warning if no existing packing has been pushed allowing
easy identification of locations where the __rte_packed_begin is
missing.

Macro __rte_packed was marked as deprecated.

Nice to have:
Some alternative solutions were discussed on the mailing list.
Please consider adding a brief summary of them with their benefits/disadvantages to the patch description, either here or in the cover letter (0/NN) of the patch series.

In the following patches in this series, the placement of the __rte_packed_begin attribute is wrong for GCC.
Like the __rte_aligned() attribute, the __rte_packed_begin attribute needs to be after the "struct" keyword, not before.

The GCC documentation [1] says:
You may specify type attributes in an enum, struct or union type declaration or definition by placing them immediately after the struct, union or enum keyword.
You can also place them just past the closing curly brace of the definition, but this is less preferred because logically the type should be fully defined at the closing brace.
You can also include type attributes in a typedef declaration.

[1] https://gcc.gnu.org/onlinedocs/gcc/Type-Attributes.html

<feature creep>
The documentation comment preceding each macro in rte_common.h should include a brief description of how to use the macro.
This goes for most macros in rte_common.h, not only the macros for packing.
</feature creep>

[PATCH v7 07/29] drivers/bus: replace packed attributes

[Andre Muezerie]

MSVC struct packing is not compatible with GCC. Replace macro
__rte_packed with __rte_packed_begin to push existing pack value
and set packing to 1-byte and macro __rte_packed_end to restore
the pack value prior to the push.

Macro __rte_packed_end is deliberately utilized to trigger a
MSVC compiler warning if no existing packing has been pushed allowing
easy identification of locations where the __rte_packed_begin is
missing.

[PATCH v7 08/29] drivers/common: replace packed attributes

[Andre Muezerie]

MSVC struct packing is not compatible with GCC. Replace macro
__rte_packed with __rte_packed_begin to push existing pack value
and set packing to 1-byte and macro __rte_packed_end to restore
the pack value prior to the push.

Macro __rte_packed_end is deliberately utilized to trigger a
MSVC compiler warning if no existing packing has been pushed allowing
easy identification of locations where the __rte_packed_begin is
missing.

[PATCH v7 09/29] drivers/compress: replace packed attributes

[Andre Muezerie]

MSVC struct packing is not compatible with GCC. Replace macro
__rte_packed with __rte_packed_begin to push existing pack value
and set packing to 1-byte and macro __rte_packed_end to restore
the pack value prior to the push.

Macro __rte_packed_end is deliberately utilized to trigger a
MSVC compiler warning if no existing packing has been pushed allowing
easy identification of locations where the __rte_packed_begin is
missing.

[PATCH v7 11/29] drivers/dma: replace packed attributes

[Andre Muezerie]

MSVC struct packing is not compatible with GCC. Replace macro
__rte_packed with __rte_packed_begin to push existing pack value
and set packing to 1-byte and macro __rte_packed_end to restore
the pack value prior to the push.

Macro __rte_packed_end is deliberately utilized to trigger a
MSVC compiler warning if no existing packing has been pushed allowing
easy identification of locations where the __rte_packed_begin is
missing.

[PATCH v7 15/29] drivers/raw: replace packed attributes

[Andre Muezerie]

MSVC struct packing is not compatible with GCC. Replace macro
__rte_packed with __rte_packed_begin to push existing pack value
and set packing to 1-byte and macro __rte_packed_end to restore
the pack value prior to the push.

Macro __rte_packed_end is deliberately utilized to trigger a
MSVC compiler warning if no existing packing has been pushed allowing
easy identification of locations where the __rte_packed_begin is
missing.

[PATCH v7 21/29] examples/l3fwd-power: replace packed attributes

[Andre Muezerie]

MSVC struct packing is not compatible with GCC. Replace macro
__rte_packed with __rte_packed_begin to push existing pack value
and set packing to 1-byte and macro __rte_packed_end to restore
the pack value prior to the push.

Macro __rte_packed_end is deliberately utilized to trigger a
MSVC compiler warning if no existing packing has been pushed allowing
easy identification of locations where the __rte_packed_begin is
missing.

[PATCH v7 28/29] lib/pipeline: replace packed attributes

[Andre Muezerie]

MSVC struct packing is not compatible with GCC. Replace macro
__rte_packed with __rte_packed_begin to push existing pack value
and set packing to 1-byte and macro __rte_packed_end to restore
the pack value prior to the push.

Macro __rte_packed_end is deliberately utilized to trigger a
MSVC compiler warning if no existing packing has been pushed allowing
easy identification of locations where the __rte_packed_begin is
missing.
