PATCH] Fix ntfw when called with FTW_CHDIR and FTW_DEPTH to change directory back to the parent before processing the directory (after the contents have already been processed).
by Ata, John (US) 18 Oct '16

18 Oct '16

Hi all, In using ftw/nftw, I've discovered a bug when using FTW_CHDIR and FTW_DEPTH. After changing the working directory to a subdirectory, nftw would process the contents fine. However, it would then try and process the directory itself while still in that directory and then switch back to the parent. This would result in an error (ENOENT). This patch will change working directories to the parent before processing the directory itself. Take care, ---- John Ata, CISSP Senior Principal Software Engineer Electronics Systems STOP Operating System<http://www.baesystems.com/en-us/our-company/inc-businesses/intelligence-and…> Software Development T 703-563-8115 | F 703-668-4359 | john.ata(a)baesystems.com<mailto:john.ata@baesystems.com> http://www.baesystems.com/csp [cid:image001.png@01D138BC.8E54E330][cid:image003.png@01D138BC.8E54E330]<http://www.twitter.com/baesystemsinc>[cid:image004.png@01D138BC.8E54E330]<http://www.youtube.com/baesystemsinc>[cid:image006.png@01D138BC.8E54E330]<http://www.flickr.com/photos/baesystemsinc/>

uClibc-ng test suite
by Waldemar Brodkorb 17 Oct '16

17 Oct '16

Hi Hackers, I had a nice talk about uClibc-ng with Alexey on ELCE2016. One of the points where the separation of the test suite included in uClibc-ng source tree. Recently Max and I discovered a problem regarding libgcc/pthread_cancel, because the code was _not_ compiled with the normal full shared gcc toolchain. Every application gets compiled and linked with full toolchain, only the test suite not. I think this is wrong and I would like to remove the test-suite from uClibc-ng source and want to create a separate project out of it. Like musl hackers are doing it with their libc-test. Furthermore I would like to synchronize the tests with GNU libc and take a look that no internal uClibc stuff is used or only when requested by the developer. So test suite could be run on GNU libc, musl and uClibc-ng based system. I would use libc-test, but they depend on GNU make and I want to be able to run the test suite on noMMU targets. @Szabolcs: Or are you interested in some joined efforts? And furthermore I like the small summary to get a fast feedback about any regressions before a release. Recently Ignacy discovered the same issue while trying to rework the internal unwind functions in uClibc-ng. Any opinions? Any suggestions for the name of the test suite? Plan is to do a release in the next days and afterwards separate the test suite code before the next release. Thanks, Waldemar

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
