+Subject: [PATCH] unix: don't use _POSIX_PATH_MAX
+
+Libuv was using _POSIX_PATH_MAX wrong. Bug introduced in commit b56d279b
+("unix: do not require PATH_MAX to be defined") from September 2018.
+
+_POSIX_PATH_MAX is the minimum max path size guaranteed by POSIX, not
+the actual max path size of the system libuv runs on. _POSIX_PATH_MAX
+is always 256, the real max is often much bigger.
+
+This commit fixes buffer overruns when processing very long paths in
+uv_fs_readlink() and uv_fs_realpath() because libuv was not allocating
+enough memory to store the result.
+
+Fixes: https://github.com/libuv/libuv/issues/2965
+PR-URL: https://github.com/libuv/libuv/pull/2966
