Guillem Jover 08188f3c 2024-02-28T04:37:44 build: Install err.h if either of the err or errc modules are built Both modules expose their functions in err.h, so we need to install it whenever any of them is being built. Reported-by: Alejandro Colomar <alx@kernel.org>
Guillem Jover 32d18dcf 2024-02-09T04:32:12 Add explicit time32 and time64 support Handle the three potential system scenarios: - system time_t is time64 - system time_t is time32 and supports time64 - system time_t is time32 and does not support time64 Add the explicit time32 and time64 functions when necessary and map them accordingly for each of these cases.
Guillem Jover 605614d6 2024-02-12T03:00:06 build: Add support for AIX
Guillem Jover ec7f5ee9 2024-02-12T01:04:37 Add vasprintf() and asprintf() functions missing on AIX These functions are used by code in the library, even though these functions started as GNU extensions, they are present in all BSDs, so we expose them as part of our interface on AIX.
Guillem Jover be4aced4 2024-02-11T23:55:40 build: Make almost all exposed interfaces use the new ABI selection Explicitly select what to include as part of the target ABI, instead of letting autoconfiguration potentially break ABI if the system grows functionality provided by the library. Make almost all the library selectable per target. Do not install manual pages for interfaces not included in the library. Control inclusion of symbols in map file via pre-processor macros, and move the comments describing the ABI selection to configure.ac. For now the header files are included as is and filtered through pre-processor conditionals. Eventually they might get switched to be autogenerated at build time.
Guillem Jover 99739877 2024-02-14T04:59:44 build: Rename ABI selection variables from need_ to abi_ This should make the purpose of these variables more clear.
Guillem Jover 304a1f83 2024-01-08T23:37:43 doc: Use macOS to refer to the operating system This is the correct spelling, instead of capitalizing it.
Guillem Jover df116b55 2024-01-07T17:43:12 Adjust strlcpy() and strlcat() per glibc adoption These functions were added in glibc 2.38, in anticipation of POSIX adopting them too. Closes: #26

Guillem Jover 6385ccc9 2023-04-18T03:58:24 build: Conditionalize bsd_getopt() on macOS The system library provides a getopt() with BSD semantics.
Guillem Jover 21d12b02 2023-04-04T23:59:05 build: On macOS do not build functions provided by the system We have never built before on macOS, so we can exclude all the functions that are currently provided in the system. Closes: #1 Closes: !3

Guillem Jover fe21244b 2022-12-20T22:47:02 include: Use __has_builtin to detect __builtin_offsetof support The __has_builtin operator is more specific and is supported by GCC and Clang, while __is_identifier() is less specific and only supported by Clang, so we should prefer the former whenever it is available, and only fallback to use the latter when the former is missing and the latter.
Guillem Jover 00b538ff 2022-11-23T23:28:34 build: Terminate lists in variables with «# EOL» This means we can add a trailing «\» to every element, so that they can be removed without requiring modification of other lines, and can be easily sorted. Replace the old usage of $(nil) which could possibly end up with junk added if such variable is ever defined, in the environment.

Guillem Jover 2f9eddc2 2022-10-05T02:05:46 include: Simplify glibc version dependent macro handling We test once whether __GLIBC__ is not defined, so we do not need to test whether it is on the OR branch afterwards. We decouple the glibc version restriction check from the _*_SOURCE variable, as that contains an implicit opposite version check.
Guillem Jover 1c3ff616 2021-02-09T02:46:49 Use uintptr_t and size_t instead of __-prefixed types in <sys/cdefs.h> The __-prefixed types cannot be assumed to be defined. Use the standard types instead. Closes: #6
Faidon Liambotis 46760262 2021-02-07T20:47:00 Update <sys/queue.h> from FreeBSD This brings <sys/queue.h> to the most up-to-date version from FreeBSD, incorporating 18 commits from the past 5 years (2015-02-24 - 2021-01-25): $ git log --oneline 9090a24aed70..8d55837dc133 sys/sys/queue.h share/man/man3/queue.3 Only minimal changes compared to the FreeBSD version have been applied (queue.3 -> queue.3bsd, _LIBBSD_ prefix).

Guillem Jover 233cab9d 2021-02-06T23:28:42 Add support for new LIBBSD_VIS_OPENBSD selection macro This will make it possible to explicitly select the OpenBSD vis implementation (the current default) for code of OpenBSD origins.
Guillem Jover 847e682f 2021-02-07T00:09:30 Use libmd hashing function implementations instead of embedding our own This splits the implementation responsibilities, and reduces embedded code copies, which was one of the driving points with this project to start with, so it's nice to give a good example.
Guillem Jover 37a9b56c 2021-02-06T23:43:12 Import pwcache module from OpenBSD
Faidon Liambotis 01f0d1ea 2020-12-31T12:46:03 Add recallocarray() and freezero() from OpenBSD Add recallocarray(), introduced in OpenBSD 6.1, and freezero(), introduced in OpenBSD 6.2. The former is imported as-is from OpenBSD, while the latter is the non-malloc-internal branch of the same code (and also the OpenSSH portable variant). Both of these originated in OpenBSD, but have also been implemented by IllumOS, cf. https://www.illumos.org/issues/8546 Documentation for these functions is in malloc(3) upstream, the relevant parts of which were previously imported in reallocarray(3bsd). Update reallocarray(3bsd) with the changes that were introduced since, and add the relevant bits for recallocarray() and freezero(), plus aliases.

Guillem Jover 5745ca03 2019-08-06T15:49:41 err: Add err(), warn(), errx() and warnx() familiy of functions Some systems such as Windows or musl-libc based ones do not have these BSD extensions. In addition libbsd itself is making use of the warnx() functions, so we better provide these interfaces in case they are missing.
Guillem Jover 9628798d 2019-08-06T15:37:43 err: Rewrite warnc() and errc() family functions to be standalone Do not depend on the system vwarn() and verr() functions to implement the *c() variants, as the system might actually lack any of the <err.h> BSD extensions.

James Clarke 61d378f5 2019-02-03T00:11:15 Re-allow direct use of nlist.n_name in <nlist.h> Commit e8d340de ("Remove a.out support from nlist()") introduced a copy of the definition of nlist from a.out.h. However, as well as having n_name inside n_un, on the various BSDs n_name could also be accessed as a direct member of nlist, and this is made use of by FreeBSD's usr.bin/netstat/main.c. Thus we should also add the same enclosing anonymous union. [guillem@hadrons.org: - Add a minimal unit test. ] Closes: !4 Signed-off-by: Guillem Jover <guillem@hadrons.org>
Aaron Dierking 48033408 2018-06-14T11:38:32 Provide a <sys/param.h> with MIN() and MAX() Windows doesn't provide <sys/param.h>. Several libbsd sources require it for MIN(), and these are useful non-system-specific macros anyway. Signed-off-by: Guillem Jover <guillem@hadrons.org>

Guillem Jover e4e15ed2 2018-05-22T13:50:44 Fix strnvis() and strnunvis() NetBSD ABI break The NetBSD implementations have different prototypes to the ones coming from OpenBSD, which will break builds, and have caused segfaults at run-time. We provide now both interfaces with different prototypes as different version nodes allow selecting them at compile-time, defaulting for now to the OpenBSD one to avoid build-time breakage, while emitting a compile-time warning. Later on, in 0.10.0, we will be switching the compile-time default to the NetBSD version. Ref: http://gnats.netbsd.org/44977 Fixes: https://bugs.debian.org/899282

Guillem Jover 1f8a3f7b 2018-03-06T01:39:45 Fix function declaration protection for glibc already providing them On non-glibc based systems we cannot unconditionally use the __GLIBC_PREREQ macro as it gets expanded before evaluation. Instead, if it is undefined, define it to 0. We should also always declare these functions on non-glibc based systems. And on systems with a new enough glibc, which provides these functions, we should still provide the declarations if _GNU_SOURCE is *not* defined. Reported-by: Jörg Krause <joerg.krause@embedded.rocks>
Guillem Jover b20272f5 2018-03-06T01:42:52 Remove <features.h> inclusion from <bsd/libutil.h> This is a non-portable header, and we should not assume it is present. Let the first system header pull it in if needed.
Guillem Jover 11ec8f1e 2018-03-06T01:41:35 Handle systems missing <sys/cdefs.h> This is a non-portable header, and we cannot expect it to be provided by the system libc (e.g. musl). We just need and rely on declaration that we have defined ourselves in our own <bsd/sys/cdefs.h>. So we switch to only ever assume that. Fixes: https://bugs.freedesktop.org/105281

Guillem Jover e8d340de 2017-06-05T05:30:27 Remove a.out support from nlist() Some libc libraries do not have an <a.out.h> header. And a.out as an executable format is very much obsolete on pretty much all currently supported systems, even if they might still support loading such objects. Remove the a.out support to increase portability.
Guillem Jover 07c76b66 2017-06-05T06:17:27 Do not use legacy BSD u_* types Some systems do not have these types available, and they are simply convenience aliases. Instead use the expanded versions which are more portable. Fixes: https://bugs.freedesktop.org/show_bug.cgi?id=101192

Guillem Jover f41fdcf1 2013-10-21T05:07:56 Add funopen() function This is a wrapper over the glibc fopencookie() function. We diverge from the FreeBSD, OpenBSD and DragonFlyBSD declarations, because seekfn() there wrongly uses fpos_t, assuming it's an integral type, and any code using that on a system where fpos_t is a struct (such as GNU-based systems or NetBSD) will fail to build. In which case, as the code has to be modified anyway, we might just as well use the correct declaration.
Guillem Jover 86cbff38 2013-10-11T05:11:42 Handle glibc partial header inclusions The glibc headers use selective inclusions through the __need_NAME mechanism to avoid circular dependencies. The problem is that if we are being overlaid, and have been requested a partial inclusion, when we pass control to the system header, then we might miss definitions needed by our own header, resulting in build failures. Workaround that by catching current partial requests, and skip the current inclusion.
Guillem Jover c5b95902 2013-07-11T12:25:54 Move setproctitle() automatic initialization to its own library The automatic initialization cannot be part of the main shared library, because there is no thread-safe way to change the environ global variable. This is not a problem if the initializaion happens just at program load time, but becomes one if the shared library is directly or indirectly dlopen()ed during the execution of the program, which could have either kept references to the old environ or could change it in some other thread. This has been observed for example on systems using Samba NSS modules. To avoid any other possible fallout, the constructor is split into a new static library that needs to be linked explicitly into programs using setproctitle(). As an additional safety measure the pkg-config linker flags will mark the program as not allowing to be dlopen()ed so that we avoid the problem described above.
