* getservice: fix handling of long linesNatanael Copa2010-10-141-22/+16
| | | | | | | | | | | | | | | Don't try to be smart by dynamically realloc buffersize as it doesn't work. Instead, be simple and allocate a buffer big enough. This fixes a memory leak when calling getserv{ent,byname,byport} multiple times. To save memory we reduce number of max aliases. We seldomly will need more than 1 anyways. While here, fix segfault that happened if there were too many aliases. Signed-off-by: Natanael Copa <natanael.copa@gmail.com> Signed-off-by: Bernhard Reutner-Fischer <rep.dot.nop@gmail.com>
* getservice: getservent_r must return ERANGE when buffer is too smallNatanael Copa2010-10-141-3/+2
| | | | | | | | | | | | | | | | | | | This fixes issue introduced by 72e1a1ce186c39f07282398e2af9eb0253e60f15 This should also fix the following testcase to exit with error rather than cause an endless loop. int main(void) { if (getservbyname("non-existing", "udp") == NULL) err(1, "getservbyname"); return 0; } Reported by Pirmin Walthert http://lists.uclibc.org/pipermail/uclibc/2010-August/044277.html Signed-off-by: Natanael Copa <natanael.copa@gmail.com> Signed-off-by: Bernhard Reutner-Fischer <rep.dot.nop@gmail.com>

* Reduce memory used by static buffers and allocate that memory dynamiclyEric Andersen2004-03-181-4/+20
| | | | | | | | | | instead. Based on an initial patch from Tobias Anderberg, but reworked. I asked Tobias to look into doing something more like what is done in busybox, but that proved to be a pain. One possible concern is that these buffers will probably show up as memory leaks i.e. with valgrind. Perhaps we should add in an atexit call to free this memory right after we allocate it?
* Fix a really dumb bug introduced in version 1.4 of this file (a patch for ipv6Eric Andersen2003-12-281-1/+3
| | | | | | | | | support) which could cause things like EOF and read errors while reading /etc/services to always return a TRY_AGAIN. The perl test suite would alloc a larger buffer and try again until all memory was exhausted. When we get a read error, or EOF, it means we didn't get what we wanted, and so we should return an error. Doing so fixes the failing perl 5.8.2 test. -Erik

* Fix a long-standing bug with pthreads. A couple of linuxthreads filesManuel Novoa III2003-12-271-2/+2
| | | | | | | | | | | | | | | | were including libc-lock.h which had a bunch of weak pragmas. Also, uClibc supplied a number of no-op weak thread functions even though many weren't needed. This combined result was that sometimes the functional versions of thread functions in pthread would not override the weaks in libc. While fixing this, I also prepended double-underscore to all necessary weak thread funcs in uClibc, and removed all unused weaks. I did a test build, but haven't tested this since these changes are a backport from my working tree. I did test the changes there and no longer need to explicitly add -lpthread in the perl build for perl to pass its thread self tests.
