2018-08-10Fix shm_open posix compliance error codeChristophe Lyon
Handle EISDIR in shm_open like glibc does, and set EINVAL. * librt/shm.c (shm_open): Handle EISDIR error. Signed-off-by: Mickaël Guêné <mickael.guene@st.com> Signed-off-by: Christophe Lyon <christophe.lyon@st.com>
2018-01-15rt: cleanup and allow to build for linuxthreadsWaldemar Brodkorb
It seems there is no real dependency to NPTL for these clock_* functions when UCLIBC_ADVANCED_REALTIME is enabled. No regressions found. Reported-by: Baruch Siach <baruch@tkos.co.il>
2017-12-10librt: fix gcc warningWaldemar Brodkorb
2017-11-22librt: fix broken posix_spawnWaldemar Brodkorb
Fix iteration over signals, synced with GNU C library code and pending patches. Issues found when running dhcpcd with hook scripts. (exit status 127) Reported-By: kapeka <kapeka@bering-uclibc.de>
2017-07-28rt: convert mq_timedsend/mq_timedreceive to use cancel.h macrosWaldemar Brodkorb
2017-04-22remove unused HP_TIMING_AVAIL and headerWaldemar Brodkorb
cleanup unused and unsupported code.
2016-11-27remove UCLIBC_HAS_LFSWaldemar Brodkorb
2016-09-26use a single libc and deduplicate threading codeWaldemar Brodkorb
Similar to musl libc a single libc has many benefits and solves some open issues with uClibc-ng. - no pthread_mutex_* weak symbols exported anymore - applications no longer failing to link when either -lrt or -lpthread are missing for dynamic and static linking mode - smaller C library - slightly better runtime performance
2016-08-10librt: fix path parsing in __spawni()Eric Le Bihan
__spawni() loops forever when parsing the path variable due to incorrect pointer update. This patch fixes the issue. Signed-off-by: Eric Le Bihan <eric.le.bihan.dev@free.fr>
2016-06-30nds32: add support for new architectureWaldemar Brodkorb
Add support for Andes Technology NDS32 architecture. See here http://www.andestech.com/en/index/index.htm for more informaton. Verification of the port from an older uClibc port was done on a sponsored AG101p board. The testsuite only has 5 errors, three are related to an existing bug in dlclose() with LT.old, also happening on cris32 and m68k. Failures to fallocate/posix_fallocate are unresolved. Thanks to Andes Technology sponsoring the hardware and being very helpful while doing the uClibc-ng porting. Signed-off-by: Waldemar Brodkorb <wbx@uclibc-ng.org>
2016-06-23libs: install backward compatibility symlinksAlexey Brodkin
Simplify the switch from uClibc to uClibc-ng. Apps already built against uClibc-0.9.x.y require .so.0 libs to present on target which in case of current uClibc-ng is not the case and those apps could not be run. This change creates symlinks from .so.1 to .so.0 for most of other libs in the same way as it was done by 23e96d89b6ab "ldso: install backward compatibility symlink by default" Signed-off-by: Alexey Brodkin <abrodkin@synopsys.com> Cc: Waldemar Brodkorb <wbx@uclibc-ng.org> Cc: Vineet Gupta <vgupta@synopsys.com> Cc: Anton Kolesov <akolesov@synopsys.com>

2015-03-31Revert "librt: Use -nodefaultlibs instead of -nostdlib"Bernhard Reutner-Fischer
This reverts commit 534f44d53146457b3ca686c47efb9207543b88e1. I don't think this is wanted. Signed-off-by: Bernhard Reutner-Fischer <rep.dot.nop@gmail.com>
2015-03-22librt: Use -nodefaultlibs instead of -nostdlibKhem Raj
nostdlib disables linking in startup files too which is not what we want here since it needs to resolve __dso_handle which comes from crtbeginS.o, otherwise librt has this undefined reference to a weak undefined __dso_handle that shows up as error (with gold linker) when shared libraries are being built which are linking in librt Signed-off-by: Khem Raj <raj.khem@gmail.com> Signed-off-by: Bernhard Reutner-Fischer <rep.dot.nop@gmail.com>
2013-12-20librt: fix mq_timed{send,receive} return instructionsBaruch Siach
Not all architectures use 'ret' as function return instruction. For example, xtensa usually uses 'retw'. Use the ret_ERRVAL arch dependant macro instead. Signed-off-by: Baruch Siach <baruch@tkos.co.il> Signed-off-by: Bernhard Reutner-Fischer <rep.dot.nop@gmail.com>

This adds support for a new binary format, DSBT ELF, to the Makefiles. Every shared library is assigned a DSBT index, and the link.so macro is adjusted to ensure the correct linker argument is passed. Configuration and ldso support will follow in separate commits.

2010-06-17librt: fix linking WRT pthreadsBernhard Reutner-Fischer
