+Subject: [PATCH 01/24] lib/path: ul_path_cpuparse: fix parsing of empty sysfs
+ files
+MIME-Version: 1.0
+Content-Type: text/plain; charset="utf-8"
+Content-Transfer-Encoding: 8bit
+
+Kernel 5.15 returns empty content for topology/thread_siblings on
+aarch64 platform, which in conjunction of uninitialized `buf` memory
+buffer results in the garbage:
+
+ (gdb) p buf
+ $14 = " @\377\367\177\000\000\000\275\000\347j\032\236"
+
+This garbage is then being later consumed by underlying helper functions
+like for example cpumask_parse() and this leads to the following crash
+later:
+
+ in __libc_free (p=0x7ff7f67c00) at src/malloc/mallocng/free.c:105
+ in free (p=<optimized out>) at src/malloc/free.c:5
+ in add_cpuset_to_array (setsize=<optimized out>, set=<optimized out>, items=<optimized out>, ary=<optimized out>) at ../sys-utils/lscpu-topology.c:29
+ in cputype_read_topology (cxt=cxt@entry=0x7ff7fffe70, ct=0x4298a0) at ../sys-utils/lscpu-topology.c:153
+ in lscpu_read_topology (cxt=cxt@entry=0x7ff7fffe70) at ../sys-utils/lscpu-topology.c:629
+ in main (argc=1, argv=0x7ffffffdb8) at ../sys-utils/lscpu.c:1341
+
+It looks like the problem is that current logic expects fgets() to set
+errno on failure, but fgets() is not documented to do so and and neither
+glibc nor musl set errno.  So if errno was set to 0 before fgets() call,
+the failure from fgets() is ignored and then invalid buffer is being
+parsed.
+
+Fixes: #1810
