Subject: [PR PATCH] musl: backport reallocarray.
Date: Mon, 24 May 2021 21:11:22 +0200 [thread overview]
Message-ID: <gh-mailinglist-notifications-41a7ca26-5023-4802-975b-f1789d68868e-void-packages-31096@inbox.vuxu.org> (raw)
[-- Attachment #1: Type: text/plain, Size: 1887 bytes --]
There is a new pull request by ericonr against master on the void-packages repository
https://github.com/ericonr/void-packages realloc
https://github.com/void-linux/void-packages/pull/31096
musl: backport reallocarray.
It's in POSIX-future and some applications have started depending on it.
It's easier to backport into musl than fix each individual package.
Since we are adding a new interface to libc, update common/shlibs entry
as well. This should probably have been done for all musl updates.

+Subject: [PATCH] implement reallocarray
+
+reallocarray is an extension introduced by OpenBSD, which introduces
+calloc overflow checking to realloc.
+
+glibc 2.28 introduced support for this function behind _GNU_SOURCE,
+while glibc 2.29 allows its usage in _DEFAULT_SOURCE.
