| path_max_zero_st_size | fix undefined path_max for st_size zero The downstream 'path_max' patch in Debian sets the buffer size for readlink() to the 'st_size' value obtained with lstat(). . However, it might be zero for some symlinks in /proc on Linux (notably /proc/self) leading to readlink() failing with EINVAL. . $ strace -e lstat stat /proc/self 2>&1 \ | grep -e lstat -e File: -e Size: lstat("/proc/self", {st_mode=S_IFLNK|0777, st_size=0, ...}) = 0 File: /proc/self -> 30875 Size: 0 Blocks: 0 IO Block: 1024 symbolic link . This causes readlink (tool) to files like /dev/stdin to fail, which may link to /proc/self/fd/0 on containers or elsewhere. . Test-case: . ubuntu@cosmic:~/node$ $ strace -E LD_LIBRARY_PATH=/usr/local/lib/ -f -e lstat,readlink \ node test/parallel/test-fs-realpath-pipe.js . With path_max: .
