2017-10-01statfs: bugfix statfs02 fstatfs02 failed in ltp-testsuiteGuo Ren
In the test-case of statfs from ltp-testsuite, it pass -1 to 2th argument. eg: fstatfs(fd , -1) When uclibc-ng parse the buf32 to buf will cause illegal address access, the kernel will signal the process with SIGSEGV. If we pass the -1 directly to the syscall of statfs/fstatfs, kernel use copy_to_user() to prevent the signal of SIGSEGV and just return EINVAL. This is the ltp-testsuite expect.

2017-07-28fix tolower and localesEugene Yudin
The function towlower doesn't work with locales different from C. Issue was introduced in commit: 8cde3a9bf2856dcb9a759dec7ecb04a68e712254 Call to setlocale is needed for correct generation of the table uplow_diff. Otherwise you receive compile time error "range assumption error" after uncommenting the call. Similar problem described here: http://lists.uclibc.org/pipermail/uclibc/2015-March/048852.html This commit fix the problem by using int32_t values.

As __UCLIBC_HAS_GETTEXT_AWARENESS__ is never defined, this is mostly dead code. It is planned to integrate libiconv-tiny and gettext-tiny into uClibc-ng after the next release, so that more software packages can be used without modification. Remove any _/_N macro usage.

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

2016-04-03Provide an alias to _obstack_freeAlexey Neyman
GDB 7.11 does not build if compiled against uclibc-ng (1.0.12 was used, but the problematic code exists in 1.0.13 as well). The reason is that GDB release includes its own obstack implementation, but elides the code if <gnu-versions.h> declares a compatible obstack implementation in libc. uclibc-ng does claim compatible obstack interface (GDB expects version 2, but accepts version 1 if sizeof(int) == sizeof(size_t)), however, uclibc-ng does not provide the _obstack_free symbol that is a part of the interface (glibc does provide this symbol). This later causes a link failure. The attached patch makes uclibc-ng enables an alias _obstack_free -> obstack_free. Signed-off-by: Alexey Neyman <stilor@att.net>
2016-02-07frv: resurrect port somehow, totally untestedWaldemar Brodkorb
The FR-V port is really broken, and I have no emulator or hardware for this platform. I tried to get some hardware from RedHat, who made the FR-V port initially. Unfortunately Fujitsi didn't agreed to sent me some of their unused spare hardware lying @RedHat. As I invested some time to get stuff compiled, I decided to add the code and may be anytime later I can gain access to some emulator or hardware. GDB simulator for FR-V doesn't support booting Linux AFAIK.

2015-12-17Fix syslog messages lost if syslogd is temporary busyVladislav Grishenko
Commit 4139fe5aec935ba3f462dcaf6aafb6e5eadf1ab9 fixes SIGSTOPed syslogd issue. but introduced new one - messages will be lost when socket buffer gets full, not only if syslogd is stalled, but even if it accepts message slower than someone sends and possibly leads to security hole, when important messages get lost as result of attacker flooding. Patch adds 1 second waiting for socket buffer can accept the message, helps when syslogd is working hard. If it's stalled/SIGSTOPed, message will be sent to errout as before. After that, further non-blocking /dev/log connect attempts will fail immediately with EAGAIN error until syslogd reads some from it. function old new delta openlog_intern 259 355 +96 static.tv - 8 +8 .rodata 151 159 +8 ------------------------------------------------------------------------------ (add/remove: 1/0 grow/shrink: 2/0 up/down: 112/0) Total: 112 bytes Signed-off-by: Vladislav Grishenko <themiron@mail.ru>

2014-12-15mkostemp: fix implementationAnthony G. Basile
mkostemp(char *template, int flags) generates a unique temporary filename from a template. The flags parameter accepts three of the same flags as open(2): O_APPEND, O_CLOEXEC, and O_SYNC. The current implementation of mkostemp(3) does not respect the flags and in fact confuses the flags with the file mode which should always be S_IRUSR | S_IWUSR. This patch corrects this issue.
