[dpdk-stable] [PATCH v5 01/17] eal: fix comment of OS-specific header files

[Thomas Monjalon]

The same comment is on top of each rte_os.h file.
It is reworded to remove the mention of "future releases".

Fixes: 428eb983f5f7 ("eal: add OS specific header file")

[dpdk-stable] [PATCH v5 02/17] buildtools: fix build with busybox

[Thomas Monjalon]

If using busybox for mktemp and awk (as in Alpine),
some bugs prevent the script from running:

1/ It seems busybox mktemp requires the pattern to have at least
6 X and no other suffix.
The same has been fixed for other scripts in the past:
commit 3771edc35438 ("buildtools: fix build for some mktemp")

2/ It seems busybox awk does not accept the regex ^.*{
except if the opening curly brace is escaped.

Fixes: 4c82473412e8 ("build: add internal tag check")
Fixes: 68b1f1cda5b4 ("build: check AVX512 rather than binutils version")
Fixes: 3290ac14eb94 ("buildtools: detect discrepancies for experimental symbols")

[dpdk-stable] [PATCH v5 03/17] build: detect execinfo library on Linux

[Thomas Monjalon]

The library execinfo and its header file can be installed on Alpine Linux
where the backtrace feature is not part of musl libc:
	apk add libexecinfo-dev

As a consequence, this library should not be restricted to BSD only.

At the same time, the library and header are detected once and added
globally to be linked with any application, internal or external.

Fixes: 9065b1fac65f ("build: fix dependency on execinfo for BSD meson builds")

[dpdk-stable] [PATCH v5 04/17] build: define _GNU_SOURCE globally

[Thomas Monjalon]

There was an intent to define _GNU_SOURCE globally,
but it was not set in pkg-config for external applications.

The internal definition in config/meson.build is kept,
and one is added in buildtools/pkg-config/meson.build for external apps.
All other specific definitions of _GNU_SOURCE are removed.

Fixes: 5d7b673d5fd6 ("mk: build with _GNU_SOURCE defined by default")
Fixes: 28188cee2aa0 ("build: enable BSD features visibility for FreeBSD")

Is this something that we really want to do, to force all external apps to
use _GNU_SOURCE when compiling? Do some of our header files rely on
definitions only available with _GNU_SOURCE? If so, we should probably look
to remove that dependency rather than mandating the define.

From patch 5:
In musl libc, cpu_set_t is defined only if _GNU_SOURCE is defined.

If we avoid mandating _GNU_SOURCE,
we must #ifdef functions relying on rte_cpuset_t in the headers:
	- rte_lcore_cpuset
	- rte_thread_set_affinity
	- rte_thread_get_affinity
	- rte_telemetry_init (internal)
Or a different trick in linux/include/rte_os.h could be:
	typedef void rte_cpuset_t;
so it allows including files, but not using above functions of course.

Can we just define _GNU_SOURCE in the header file with rte_cpuset_t?

That would be the simplest solution yes :)
I don't really like defining such flag in a header file because
it impacts all code coming after the include.
It would mean all includes done after DPDK ones behave differently.

I vote for the trick:
#ifdef _GNU_SOURCE
	typedef cpu_set_t rte_cpuset_t;
#else
	typedef void rte_cpuset_t;
#endif

Opinions?

I changed my mind, I think it is saner to not export functions
which use rte_cpuset_t, if the type is not defined.
The type definition is detected thanks to CPU_SETSIZE
and a new definition is used inside DPDK: RTE_HAS_CPUSET.
I think it is more elegant and easier to debug.
I am sending a v6.

[dpdk-stable] [PATCH v5 05/17] eal/linux: fix build with musl

[Thomas Monjalon]

In musl libc, cpu_set_t is defined only if _GNU_SOURCE is defined.
In case _GNU_SOURCE is undefined, as in eal_common_errno.c,
it was not possible to include rte_os.h which uses cpu_set_t.

This limitation is removed: if _GNU_SOURCE is not defined,
cpu_set_t related definitions are skipped.
Note: such definitions are unneeded in eal_common_errno.c.

A missing include of fcntl.h is also added.

[dpdk-stable] [PATCH v5 06/17] drivers: fix header includes for musl

[Thomas Monjalon]

The header files argp.h and error.h do not exist in musl libc
and are not needed in dpaa code.

The header file fcntl.h should not be included from sys/ directory
as done in dlb drivers, it is an error with musl libc.

[dpdk-stable] [PATCH v5 08/17] bus/pci: support I/O port operations with musl

[Thomas Monjalon]

From: Natanael Copa <ncopa@alpinelinux.org>

Add a fallback for non-GNU libc systems like musl libc for the
non-standard functions outl_p, outw_p and outb_p.

This solves the following buildtime errors when building with musl libc:
pci_uio.c:(.text+0xaa1): undefined reference to `outw_p'
pci_uio.c:(.text+0xac5): undefined reference to `outl_p'
pci_uio.c:(.text+0xadf): undefined reference to `outb_p'

The non-x86 case are handled with macros to factor out various ifdefs.

There is no standard saying that __WORDSIZE should be be defined or in

This solves a warning when building with musl libc:

 warning: "__WORDSIZE" is not defined, evaluates to 0 [-Wundef]

[dpdk-stable] [PATCH v5 10/17] bus/dpaa: fix build with musl

[Thomas Monjalon]

From: Natanael Copa <ncopa@alpinelinux.org>

Fix build with musl libc by using warn(3) instead of using the GNU
specific error(3).

`error(0, errno, ...)` is identical to `warn(...)` so replace:

  error(0, ret, ...);

with the identical:

  errno = ret;
  warn(...);

We could have used the identical `warnx("...: %s", strerror(ret))` but
strerror(3) is not thread-safe and the strerror_r variant has two
incompatible versions, one GNU specific and one XSI-compliant. Avoid the
mess by letting `warn` use the thread-local errno.

This also fixes error message for kzmalloc failures which previously
would always have given "Unknown error -1", since that is what
strerror(-1) returns. Let 'warn' use the proper error message from errno
which is set by kzalloc.

[dpdk-stable] [PATCH v5 11/17] common/dpaax/caamflib: fix build with musl

[Thomas Monjalon]

From: Natanael Copa <ncopa@alpinelinux.org>

The swab16/swab32/swab64 are Linux specific and not GNU libc specific.
Keep the check for __GLIBC__ just in case other GNU systems depends on
this (Hurd or GNU/kFreeBSD).

This fixes a build error with musl libc.

[dpdk-stable] [PATCH v5 16/17] app/testpmd: fix build with musl

[Thomas Monjalon]

From: Natanael Copa <ncopa@alpinelinux.org>

1/ Improve portability by avoiding use of non-standard 'uint'.
Use uint8_t for hash_key_len as rss_key_len is a uint8_t type.
This solves following build error when building with musl libc:
    app/test-pmd/testpmd.h:813:29: error: unknown type name 'uint'

2/ In musl libc, stdout is of type (FILE * const).
Because of the const qualifier, a dark magic cast
must be achieved through uintptr_t.

[dpdk-stable] [PATCH v6 02/17] buildtools: fix build with busybox

[Thomas Monjalon]

If using busybox for mktemp and awk (as in Alpine),
some bugs prevent the script from running:

1/ It seems busybox mktemp requires the pattern to have at least
6 X and no other suffix.
The same has been fixed for other scripts in the past:
commit 3771edc35438 ("buildtools: fix build for some mktemp")

2/ It seems busybox awk does not accept the regex ^.*{
except if the opening curly brace is escaped.

[dpdk-stable] [PATCH v6 03/17] build: detect execinfo library on Linux

[Thomas Monjalon]

The library execinfo and its header file can be installed on Alpine Linux
where the backtrace feature is not part of musl libc:
	apk add libexecinfo-dev

As a consequence, this library should not be restricted to BSD only.

At the same time, the library and header are detected once and added
globally to be linked with any application, internal or external.

[dpdk-stable] [PATCH v6 04/17] build: remove redundant _GNU_SOURCE definitions

[Thomas Monjalon]

The feature macro _GNU_SOURCE is defined globally,
but there was some remaining useless settings.

The internal definition in config/meson.build is kept,
all other internal definitions of _GNU_SOURCE are removed,
except in examples, which can be built as external applications.
Note: external applications do not inherit of _GNU_SOURCE.

Fixes: 5d7b673d5fd6 ("mk: build with _GNU_SOURCE defined by default")
Fixes: 28188cee2aa0 ("build: enable BSD features visibility for FreeBSD")
Fixes: e6cdc54cc0ef ("net/mlx5: add socket server for external tools")

[dpdk-stable] [PATCH v6 05/17] eal: fix build with musl

[Thomas Monjalon]

In musl libc, cpu_set_t is defined only if _GNU_SOURCE is defined.
In case _GNU_SOURCE is undefined, as in eal_common_errno.c,
it was not possible to include rte_os.h which uses cpu_set_t.

This limitation is removed: if CPU_SETSIZE is not defined,
cpu_set_t related definitions and functions are skipped.
Note: such definitions are unneeded in eal_common_errno.c.

Applications which do not define _GNU_SOURCE may miss cpu_set_t related
features on musl. Such case is detected by RTE_HAS_CPUSET being undefined,
so functions which depend on rte_cpuset_t will be unavailable.

A missing include of fcntl.h is also added.

Bugzilla ID: 35
Fixes: 11b57c698005 ("eal: fix error string function")
Fixes: 176bb37ca6f3 ("eal: introduce internal wrappers for file operations")

The header files argp.h and error.h do not exist in musl libc
and are not needed in dpaa code.

The header file fcntl.h should not be included from sys/ directory
as done in dlb drivers, it is an error with musl libc.

[dpdk-stable] [PATCH v6 08/17] bus/pci: support I/O port operations with musl

[Thomas Monjalon]

From: Natanael Copa <ncopa@alpinelinux.org>

Add a fallback for non-GNU libc systems like musl libc for the
non-standard functions outl_p, outw_p and outb_p.

This solves the following buildtime errors when building with musl libc:
pci_uio.c:(.text+0xaa1): undefined reference to `outw_p'
pci_uio.c:(.text+0xac5): undefined reference to `outl_p'
pci_uio.c:(.text+0xadf): undefined reference to `outb_p'

The non-x86 case are handled with macros to factor out various ifdefs.

[dpdk-stable] [PATCH v6 09/17] bus/dpaa: fix 64-bit arch detection

[Thomas Monjalon]

From: Natanael Copa <ncopa@alpinelinux.org>

There is no standard saying that __WORDSIZE should be be defined or in
what include it should be defined. Use RTE_ARCH_64 instead.

This solves a warning when building with musl libc:

 warning: "__WORDSIZE" is not defined, evaluates to 0 [-Wundef]

[dpdk-stable] [PATCH v6 10/17] bus/dpaa: fix build with musl

[Thomas Monjalon]

From: Natanael Copa <ncopa@alpinelinux.org>

Fix build with musl libc by using warn(3) instead of using the GNU
specific error(3).

`error(0, errno, ...)` is identical to `warn(...)` so replace:

  error(0, ret, ...);

with the identical:

  errno = ret;
  warn(...);

We could have used the identical `warnx("...: %s", strerror(ret))` but
strerror(3) is not thread-safe and the strerror_r variant has two
incompatible versions, one GNU specific and one XSI-compliant. Avoid the
mess by letting `warn` use the thread-local errno.

This also fixes error message for kzmalloc failures which previously
would always have given "Unknown error -1", since that is what
strerror(-1) returns. Let 'warn' use the proper error message from errno
which is set by kzalloc.

The swab16/swab32/swab64 are Linux specific and not GNU libc specific.
Keep the check for __GLIBC__ just in case other GNU systems depends on
this (Hurd or GNU/kFreeBSD).

This fixes a build error with musl libc.

[Thomas Monjalon]

From: Natanael Copa <ncopa@alpinelinux.org>

1/ Improve portability by avoiding use of non-standard 'uint'.
Use uint8_t for hash_key_len as rss_key_len is a uint8_t type.
This solves following build error when building with musl libc:
    app/test-pmd/testpmd.h:813:29: error: unknown type name 'uint'

2/ In musl libc, stdout is of type (FILE * const).
Because of the const qualifier, a dark magic cast
must be achieved through uintptr_t.

The header file unistd.h should not be included from sys/ directory,
it is an error with musl libc.

[dpdk-stable] [PATCH v7 02/17] buildtools: fix build with busybox

[Thomas Monjalon]

If using busybox for mktemp and awk (as in Alpine),
some bugs prevent the script from running:

1/ It seems busybox mktemp requires the pattern to have at least
6 X and no other suffix.
The same has been fixed for other scripts in the past:
commit 3771edc35438 ("buildtools: fix build for some mktemp")

2/ It seems busybox awk does not accept the regex ^.*{
except if the opening curly brace is escaped.

Fixes: 4c82473412e8 ("build: add internal tag check")
Fixes: 68b1f1cda5b4 ("build: check AVX512 rather than binutils version")

Does it make sense to change it to

DUMPFILE=$(mktemp -t dpdk.${0##*/}.objdump.XXXXXX) 

So we can preserve what the file is in the filename?

Yes could be.
There is already the name of the script in the temp filename,
but I am OK to add more details.

If there is no other comment, I will change when applying.

[dpdk-stable] [PATCH v7 03/17] build: detect execinfo library on Linux

[Thomas Monjalon]

The library execinfo and its header file can be installed on Alpine Linux
where the backtrace feature is not part of musl libc:
	apk add libexecinfo-dev

As a consequence, this library should not be restricted to BSD only.

At the same time, the library and header are detected once and added
globally to be linked with any application, internal or external.

Fixes: 9065b1fac65f ("build: fix dependency on execinfo for BSD meson builds")

[dpdk-stable] [PATCH v7 04/17] build: remove redundant _GNU_SOURCE definitions

[Thomas Monjalon]

The feature macro _GNU_SOURCE is defined globally,
but there was some remaining useless settings.

The internal definition in config/meson.build is kept,
all other internal definitions of _GNU_SOURCE are removed,
except in examples, which can be built as external applications.
Note: external applications do not inherit of _GNU_SOURCE.

Fixes: 5d7b673d5fd6 ("mk: build with _GNU_SOURCE defined by default")

[dpdk-stable] [PATCH v7 05/17] eal: fix build with musl

[Thomas Monjalon]

In musl libc, cpu_set_t is defined only if _GNU_SOURCE is defined.
In case _GNU_SOURCE is undefined, as in eal_common_errno.c,
it was not possible to include rte_os.h which uses cpu_set_t.

This limitation is removed: if CPU_SETSIZE is not defined,
cpu_set_t related definitions and functions are skipped.
Note: such definitions are unneeded in eal_common_errno.c.

Applications which do not define _GNU_SOURCE may miss cpu_set_t related
features on musl. Such case is detected by RTE_HAS_CPUSET being undefined,
so functions which depend on rte_cpuset_t will be unavailable.

A missing include of fcntl.h is also added.

Bugzilla ID: 35
Fixes: 11b57c698005 ("eal: fix error string function")
Fixes: 176bb37ca6f3 ("eal: introduce internal wrappers for file operations")

[dpdk-stable] [PATCH v7 07/17] common/dpaax/caamflib: fix build with musl

[Thomas Monjalon]

From: Natanael Copa <ncopa@alpinelinux.org>

The swab16/swab32/swab64 are Linux specific and not GNU libc specific.
Keep the check for __GLIBC__ just in case other GNU systems depends on
this (Hurd or GNU/kFreeBSD).

This fixes a build error with musl libc.

[dpdk-stable] [PATCH v7 09/17] bus/dpaa: fix 64-bit arch detection

[Thomas Monjalon]

From: Natanael Copa <ncopa@alpinelinux.org>

There is no standard saying that __WORDSIZE should be be defined or in
what include it should be defined. Use RTE_ARCH_64 instead.

This solves a warning when building with musl libc:

 warning: "__WORDSIZE" is not defined, evaluates to 0 [-Wundef]

[dpdk-stable] [PATCH v7 10/17] bus/dpaa: fix build with musl

[Thomas Monjalon]

From: Natanael Copa <ncopa@alpinelinux.org>

The header files argp.h and error.h do not exist in musl libc.

Fix build with musl libc by using err(3) instead of
the GNU-specific error(3).

We could have used the identical errx("...: %s", strerror(ret))` but
strerror(3) is not thread-safe and the strerror_r variant has two
incompatible versions, one GNU specific and one XSI-compliant.
Avoid the mess by letting "err" use the thread-local errno.

This also fixes error message for kzmalloc failures which previously
would always have given "Unknown error -1", since that is what
strerror(-1) returns. Let "err" use the proper error message from errno
which is set by kzalloc.

Fixes: 9d32ef0f5d61 ("bus/dpaa: support creating dynamic HW portal")
Fixes: f09ede6c8fd1 ("bus/dpaa: add BMAN driver core")
Fixes: 5b22cf744689 ("bus/dpaa: introducing FMan configurations")

[dpdk-stable] [PATCH v7 11/17] bus/pci: support I/O port operations with musl

[Thomas Monjalon]

Add a fallback for non-GNU libc systems like musl libc for the
non-standard functions outl_p, outw_p and outb_p.

It solves the following errors when building with musl libc:
	pci_uio.c: undefined reference to 'outw_p'
	pci_uio.c: undefined reference to 'outl_p'
	pci_uio.c: undefined reference to 'outb_p'

[dpdk-stable] [PATCH v7 16/17] app/testpmd: fix build with musl

[Thomas Monjalon]

From: Natanael Copa <ncopa@alpinelinux.org>

1/ Improve portability by avoiding use of non-standard 'uint'.
Use uint8_t for hash_key_len as rss_key_len is a uint8_t type.
This solves following build error when building with musl libc:
    app/test-pmd/testpmd.h:813:29: error: unknown type name 'uint'

2/ In musl libc, stdout is of type (FILE * const).
Because of the const qualifier, a dark magic cast
must be achieved through uintptr_t.

Fixes: 8205e241b2b0 ("app/testpmd: add missing type to RSS hash commands")
Fixes: e977e4199a8d ("app/testpmd: add commands to load/unload BPF filters")
