Guillem Jover 1fb25b7d 2021-02-09T06:14:25 Release libbsd 0.11.3
Guillem Jover 31f034e3 2021-02-09T05:57:37 Switch libmd wrapper to use dlsym() Switch from the previous versioned symbol implementation which required users to also link against the message digest provider explicitly, or they would fail to find the symbols, to an implementation that loads the symbols from the linked library providing the functions using dlsym(), thus preserving backwards compatibility.
Guillem Jover a4e0db2b 2021-02-09T06:04:38 build: Use a single variable to track libraries to link against Using various variables means we have to keep these in sync in various places. Just use a single variable that we can use anywhere where this is needed.
Guillem Jover 43d34c9d 2021-02-09T06:02:46 build: Fix message digest library checks They were not failing when not finding the SHA-2 functions and were hardcoding -lmd regardless of what library had been found.
Guillem Jover 2374f409 2021-02-09T05:56:49 build: Add a Libs.private field to pkg-config file We need to list all internal libraries there so that we can statically link.
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
Guillem Jover e832b768 2021-02-08T03:45:06 closefrom: Use close_range() on Linux when available Closes: !11 Based-on-patch-by: cptpcrd <cptpcrd.git@gmail.com> Signed-off-by: Guillem Jover <guillem@hadrons.org>
cptpcrd c4fca5bb 2021-02-07T14:22:21 closefrom: Handle lowfd < 0 properly More important if close_range() is going to be used, since casting negative values to 'unsigned int' might hide the errors. [guillem@hadrons.org: Minor coding style fix. ] Signed-off-by: Guillem Jover <guillem@hadrons.org>
Guillem Jover a1f79978 2021-02-08T02:52:50 closefrom: Import some changes from sudo Take most of the changes done in sudo, but preserve the existing local changes and refactoring. In addition, refactor pstat implementation into closefrom_pstat(), so that the code is easier to read, and requires no conditional declarations.
Guillem Jover edea268c 2021-02-08T03:59:56 Release libbsd 0.11.2
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 a4de4d95 2021-02-07T02:03:59 Release libbsd 0.11.1
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 2462cd88 2021-02-07T00:23:43 Release libbsd 0.11.0
Guillem Jover d54ceb37 2021-02-07T00:09:45 Update copyright claims
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.

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 a11c98a6 2019-08-07T18:34:09 Release libbsd 0.10.0
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>

Guillem Jover 890699a7 2019-08-06T18:51:45 build: Abstract symbol versioning via new libbsd_symver_* macros This makes it more obvious what they are doing. It will make it easier to make these directives more portable, as they are really ELF specific.
Guillem Jover b0ebb0d4 2019-08-06T23:16:42 build: Use __register_atfork() only if really available This is a glibc-specific symbol that has no public declaration. But is being used by the OpenBSD and this implementation as a hack to avoid having to link against the pthread library. This interface is at least included in LSB 5.0 [L], and using pthread_atfork() is otherwise problematic anyway [P]. [L] <https://refspecs.linuxfoundation.org/LSB_5.0.0/LSB-Core-generic/LSB-Core-generic/baselib---register-atfork.html> [P] <http://austingroupbugs.net/view.php?id=851> One problem is that we were using it whenever __GLIBC__ is defined, which is supposed to be defined only on an actual glibc, but uClibc defines that macro, but it does not provide the symbol on its noMMU variant. We add a new configure check that will try to link a program that uses that symbol to make sure it is present. Closes: !2 Reported-by: Fabrice Fontaine <fontaine.fabrice@gmail.com>

Guillem Jover 8e2d5504 2018-06-06T05:41:34 Fix vis family of functions to not leak The code uses an internal helper function to avoid code repetition. But to get there, the function takes a pointer to a pointer, so that the few functions that require returning an allocated buffer can get hold of it this way. The problem is that the user might pass a NULL pointer and trigger an internal allocation even if the functions are not expected to do so. Add a new internal helper for non-allocations, that will assert that condition, and make any other function that requires this behavior call this one instead. Warned-by: coverity

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
