Here's the outout of the console:
n22 /mnt/ramdisk/src # make clean
CLEAN arch/i386/boot/compressed
CLEAN arch/i386/boot
CLEAN /mnt/ramdisk/src
CLEAN arch/i386/kernel
CLEAN drivers/char
CLEAN drivers/video/logo
CLEAN init
CLEAN kernel
CLEAN lib
CLEAN usr
CLEAN .tmp_versions
and here the process table:
make,9149 clean
└─sh,9665 -c echo\040'\040\040CLEAN\040\040\040.tmp_versions'\040&&\040rm\040-rf\040.tmp_versions
└─rm,9666 -rf .tmp_versions
Same behaviour for 1.1.4-r1: n22 /mnt/ramdisk/src # make clean CLEAN arch/i386/boot/compressed CLEAN arch/i386/boot CLEAN /mnt/ramdisk/src CLEAN arch/i386/kernel CLEAN drivers/char CLEAN drivers/video/logo CLEAN init CLEAN kernel CLEAN lib CLEAN usr CLEAN .tmp_versions << hanging at this point :-( Could you try to do this without a temporary file system? That is, with /mnt/ramdisk as an ext{2,3}, reiserfs or xfs partition.
Ok, doing the same under /root (ext3fs) :
n22 ~ # pwd
/root
n22 ~ # modprobe unionfs
n22 ~ # mkdir src
n22 ~ # mkdir src_overlay
n22 ~ # mount -t unionfs -o dirs=/root/src_overlay/=rw:/usr/src/linux-2.6.15-gentoo-r1/=ro unionfs /root/src
n22 ~ # unionctl /root/src --list
/root/src_overlay (rw-)
/usr/src/linux-2.6.15-gentoo-r1 (r--)
n22 ~/src # make clean
CLEAN arch/i386/boot/compressed
CLEAN arch/i386/boot
CLEAN /root/src
CLEAN arch/i386/kernel
CLEAN drivers/char
CLEAN drivers/video/logo
CLEAN init
CLEAN kernel
CLEAN lib
CLEAN usr
CLEAN .tmp_versions
hanging here :-(
issue went away using newer kernel and/or glibc, now the kernel oopses, reported upstream : https://bugzilla.fsl.cs.sunysb.edu/show_bug.cgi?id=499 |
To play with different kernel versinos without changing the current state I mounted the linux src directory using unionfs onto a directory at a ramdisk - here are the fstab definition : n22 ~ # grep ramdisk /etc/fstab # (tmpfs is a dynamically expandable/shrinkable ramdisk, and will tmpfs /mnt/ramdisk tmpfs noauto,user,size=660M using the following commands: n22 ~ # modprobe unionfs n22 ~ # mkdir /mnt/ramdisk/src n22 ~ # mkdir /mnt/ramdisk/src_overlay n22 ~ # mount -t unionfs -o dirs=/mnt/ramdisk/src_overlay/=rw:/usr/src/linux-2.6.15-gentoo-r1/=ro unionfs /mnt/ramdisk/src n22 ~ # cd /mnt/ramdisk/src Then I did an n22 /mnt/ramdisk/src # make clean and this commands hangs :-( The strace outout follows: n22 /mnt/ramdisk/src # strace make clean execve("/usr/bin/make", ["make", "clean"], [/* 43 vars */]) = 0 uname({sys="Linux", node="n22", ...}) = 0 brk(0) = 0x8069000 access("/etc/ld.so.preload", R_OK) = -1 ENOENT (No such file or directory) open("/etc/ld.so.cache", O_RDONLY) = 3 fstat64(3, {st_mode=S_IFREG|0644, st_size=87958, ...}) = 0 mmap2(NULL, 87958, PROT_READ, MAP_PRIVATE, 3, 0) = 0xb7f8a000 close(3) = 0 open("/lib/tls/librt.so.1", O_RDONLY) = 3 read(3, "\177ELF\1\1\1\0\0\0\0\0\0\0\0\0\3\0\3\0\1\0\0\0P\36\0\000"..., 512) = 512 fstat64(3, {st_mode=S_IFREG|0755, st_size=33376, ...}) = 0 mmap2(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0xb7f89000 mmap2(NULL, 33384, PROT_READ|PROT_EXEC, MAP_PRIVATE|MAP_DENYWRITE, 3, 0) = 0xb7f80000 mmap2(0xb7f87000, 8192, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_FIXED|MAP_DENYWRITE, 3, 0x6) = 0xb7f87000 close(3) = 0 open("/lib/tls/libc.so.6", O_RDONLY) = 3 read(3, "\177ELF\1\1\1\0\0\0\0\0\0\0\0\0\3\0\3\0\1\0\0\0\20P\1\000"..., 512) = 512 fstat64(3, {st_mode=S_IFREG|0755, st_size=1214968, ...}) = 0 mmap2(NULL, 1154236, PROT_READ|PROT_EXEC, MAP_PRIVATE|MAP_DENYWRITE, 3, 0) = 0xb7e66000 mmap2(0xb7f7a000, 16384, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_FIXED|MAP_DENYWRITE, 3, 0x114) = 0xb7f7a000 mmap2(0xb7f7e000, 7356, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_FIXED|MAP_ANONYMOUS, -1, 0) = 0xb7f7e000 close(3) = 0 open("/lib/tls/libpthread.so.0", O_RDONLY) = 3 read(3, "\177ELF\1\1\1\0\0\0\0\0\0\0\0\0\3\0\3\0\1\0\0\0\260H\0"..., 512) = 512 fstat64(3, {st_mode=S_IFREG|0755, st_size=113349, ...}) = 0 mmap2(NULL, 70104, PROT_READ|PROT_EXEC, MAP_PRIVATE|MAP_DENYWRITE, 3, 0) = 0xb7e54000 mmap2(0xb7e62000, 8192, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_FIXED|MAP_DENYWRITE, 3, 0xe) = 0xb7e62000 mmap2(0xb7e64000, 4568, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_FIXED|MAP_ANONYMOUS, -1, 0) = 0xb7e64000 close(3) = 0 mmap2(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0xb7e53000 mprotect(0xb7e62000, 4096, PROT_READ) = 0 mprotect(0xb7f7a000, 4096, PROT_READ) = 0 mprotect(0xb7fb5000, 4096, PROT_READ) = 0 set_thread_area({entry_number:-1 -> 6, base_addr:0xb7e536c0, limit:1048575, seg_32bit:1, contents:0, read_exec_only:0, limit_in_pages:1, seg_not_present:0, useable:1}) = 0 munmap(0xb7f8a000, 87958) = 0 set_tid_address(0xb7e53708) = 12453 rt_sigaction(SIGRTMIN, {0xb7e58400, [], SA_SIGINFO}, NULL, 8) = 0 rt_sigaction(SIGRT_1, {0xb7e58480, [], SA_RESTART|SA_SIGINFO}, NULL, 8) = 0 rt_sigprocmask(SIG_UNBLOCK, [RTMIN RT_1], NULL, 8) = 0 getrlimit(RLIMIT_STACK, {rlim_cur=8192*1024, rlim_max=RLIM_INFINITY}) = 0 _sysctl({{CTL_KERN, KERN_VERSION}, 2, 0xbf9b226c, 32, (nil), 0}) = 0 open("/dev/urandom", O_RDONLY) = 3 read(3, "\245\253\fz", 4) = 4 close(3) = 0 open("/usr/lib/locale/locale-archive", O_RDONLY|O_LARGEFILE) = -1 ENOENT (No such file or directory) brk(0) = 0x8069000 brk(0x808a000) = 0x808a000 open("/usr/share/locale/locale.alias", O_RDONLY) = 3 fstat64(3, {st_mode=S_IFREG|0644, st_size=2586, ...}) = 0 mmap2(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0xb7f9f000 read(3, "# Locale name alias data base.\n#"..., 4096) = 2586 read(3, "", 4096) = 0 close(3) = 0 munmap(0xb7f9f000, 4096) = 0 open("/usr/lib/locale/de_DE@euro/LC_CTYPE", O_RDONLY) = 3 fstat64(3, {st_mode=S_IFREG|0644, st_size=208004, ...}) = 0 mmap2(NULL, 208004, PROT_READ, MAP_PRIVATE, 3, 0) = 0xb7e20000 close(3) = 0 rt_sigaction(SIGHUP, {0x804b430, [HUP], SA_RESTART}, {SIG_DFL}, 8) = 0 rt_sigaction(SIGQUIT, {0x804b430, [QUIT], SA_RESTART}, {SIG_DFL}, 8) = 0 rt_sigaction(SIGINT, {0x804b430, [INT], SA_RESTART}, {SIG_DFL}, 8) = 0 rt_sigaction(SIGTERM, {0x804b430, [TERM], SA_RESTART}, {SIG_DFL}, 8) = 0 rt_sigaction(SIGXCPU, {0x804b430, [XCPU], SA_RESTART}, {SIG_DFL}, 8) = 0 rt_sigaction(SIGXFSZ, {0x804b430, [XFSZ], SA_RESTART}, {SIG_DFL}, 8) = 0 rt_sigaction(SIGCHLD, {SIG_DFL}, {SIG_DFL}, 8) = 0 getcwd("/mnt/ramdisk/src", 4096) = 17 stat64("/usr/include", {st_mode=S_IFDIR|0755, st_size=24576, ...}) = 0 stat64("/usr/gnu/include", 0xbf9b0c00) = -1 ENOENT (No such file or directory) stat64("/usr/local/include", 0xbf9b0c00) = -1 ENOENT (No such file or directory) stat64("/usr/include", {st_mode=S_IFDIR|0755, st_size=24576, ...}) = 0 rt_sigaction(SIGCHLD, {0x8052340, [CHLD], SA_RESTART}, {SIG_DFL}, 8) = 0 rt_sigaction(SIGUSR1, {0x8054460, [USR1], SA_RESTART}, {SIG_DFL}, 8) = 0 stat64(".", {st_mode=S_IFDIR|0755, st_size=180, ...}) = 0 open(".", O_RDONLY|O_NONBLOCK|O_LARGEFILE|O_DIRECTORY) = 3 fstat64(3, {st_mode=S_IFDIR|0755, st_size=180, ...}) = 0 fcntl64(3, F_SETFD, FD_CLOEXEC) = 0 getdents64(3, n22 ~ #
