uclibc-ng 1.0.18 - libc.a binaries freeze
by Lance Fredrickson 10 Oct '16

10 Oct '16

Using uclibc-ng 1.0.18, binaries linked against dynamic libc.so seems to work just fine. Binaries created completely statically are non-responsive, and freeze up on the console. A few binaries I've tried are openvpn, tinc, transmission-daemon. I have to send SIGKILL to terminate the process. A simple hello world did compile and run fine though, so possibly having to do with additional functionality placed into libc.a. Here's a strace of one binary if that offers any insight. root@R7000:~/src/tinc-1.1pre14/src# strace ./tinc --version execve("./tinc", ["./tinc", "--version"], [/* 24 vars */]) = 0 brk(NULL) = 0x1ef000 brk(0x1efcb4) = 0x1efcb4 set_tls(0x1ef490, 0x1c4220, 0x1e9418, 0x1e8bd8, 0x4) = 0 set_tid_address(0x1ef068) = 9961 set_robust_list(0x1ef070, 12) = -1 ENOSYS (Function not implemented) rt_sigaction(SIGRTMIN, {0x165014, [], SA_RESTORER|SA_SIGINFO, 0x14f058}, NULL, 8) = 0 rt_sigaction(SIGRT_1, {0x164ea0, [], SA_RESTORER|SA_RESTART|SA_SIGINFO, 0x14f058}, NULL, 8) = 0 rt_sigprocmask(SIG_UNBLOCK, [RTMIN RT_1], NULL, 8) = 0 ugetrlimit(RLIMIT_STACK, {rlim_cur=8192*1024, rlim_max=RLIM_INFINITY}) = 0 open("/dev/urandom", O_RDONLY) = 3 read(3, "\\\177t)", 4) = 4 close(3) = 0 ioctl(0, TCGETS, {B38400 opost isig icanon echo ...}) = 0 ioctl(1, TCGETS, {B38400 opost isig icanon echo ...}) = 0 rt_sigprocmask(SIG_SETMASK, ~[ILL TRAP BUS FPE SEGV RTMIN RT_1], [], 8) = 0 rt_sigaction(SIGILL, {0x98734, ~[ILL TRAP BUS FPE SEGV RTMIN RT_1], SA_RESTORER, 0x14f04c}, {SIG_DFL, [], 0}, 8) = 0 rt_sigprocmask(SIG_BLOCK, NULL, ~[ILL TRAP BUS FPE KILL SEGV STOP RTMIN RT_1], 8) = 0 --- SIGILL {si_signo=SIGILL, si_code=ILL_ILLOPC, si_addr=0x98800} --- futex(0x1e5df0, FUTEX_WAIT_PRIVATE, 2, NULL thanks, Lance

by Waldemar Brodkorb 27 Sep '16

27 Sep '16

Hi Embedded Hackers, I cut a new release today. I think most important change is the commit: use a single libc and deduplicate threading code Please report any breakage or regressions. Have fun! Thanks Waldemar Here are the complete changes: Eric Le Bihan (1): librt: fix path parsing in __spawni() Eugeniy Paltsev (1): ARC: Fix max ULP for cosine test Leonid Lisovskiy (1): linuxthreads: Fix up pthread.h for XPG7. Rahul Bedarkar (1): elf-{fdpic, dsbt}.h: avoid void pointer's subtraction Vineet Gupta (1): ARC: Support syscall ABI v4 Waldemar Brodkorb (21): sunrpc: Do not use alloca in clntudp_call arm: fix compile in thumb mode linuxthreads: install libpthread_nonshared.a delete dead code, use -Wdeclaration-after-statement by default mips: add NaN support remove DOMULTI support test: disable regex tests microblaze: fixup headers to make gdb compile happy sync header with glibc remove dead code and documentation always assume tgkill is present linuxthreads: use tkill syscall for raise test: sync tst-atfork2 with GNU libc use a single libc and deduplicate threading code locale: cleanup support microblaze: add ulps file test: fix parallel build issue ldd: fix compile for some architectures test: remove ULPs for unsupported architecture locale: disable parallel build as it is broken here bump for release
