Subject: coreutils: patch possible infinite loop with SEEK_HOLE
X-Git-Url: http://git.99rst.org/?a=commitdiff_plain;h=1938656f70e350424099a3e7c75aea0891de14d8;p=openwrt-packages.git

coreutils: patch possible infinite loop with SEEK_HOLE

cp, install, and mv no longer enter an infinite loop copying sparse files
with SEEK_HOLE. E.g., this was seen on ext4 when copying sparse files with
extents that are being actively updated, and copy offload is not being used.

+Subject: [PATCH] copy: fix possible infinite loop with SEEK_HOLE
+
+Commit v9.8-95-g4c0cf3864 intended to initialize
+ext_start to src_pos, as was described at:
+https://lists.gnu.org/r/coreutils/2025-11/msg00035.html
+However ipos was inadvertently used, which is only
+valid the first time through the loop.
+
+* src/copy-file-data.c (lseek_copy): Use scan_inference->hole_start
+only with the initial offset passed to lseek_copy().
+Reported at https://github.com/coreutils/coreutils/issues/159
