Package: libc6
Severity: important
Dear Maintainer,
getaddrinfo/freeaddrinfo seems to have a memory leak.
Testcode:
#include <stdio.h>
#include <string.h>
#include <sys/types.h>
#include <sys/socket.h>
#include <netdb.h>
int main(void)
{
struct addrinfo *addrinfo, hints;
memset(&hints, 0 ,sizeof(hints));
hints.ai_family = AF_UNSPEC;
hints.ai_socktype = SOCK_STREAM;
hints.ai_flags = AI_NUMERICSERV | AI_ADDRCONFIG;
int rc;
if ((rc = getaddrinfo("localhost", "80", &hints, &addrinfo)) == 0) {
freeaddrinfo(addrinfo);
}
printf("rc=%d\n", rc);
return 0;
}
Valgrind throws out:
==10088== HEAP SUMMARY:
==10088== in use at exit: 28 bytes in 1 blocks
==10088== total heap usage: 45 allocs, 44 frees, 7,337 bytes allocated

==10088== by 0x400625: main (in /usr/oms/src/wget2/examples/x)
==10088==
==10088== LEAK SUMMARY:
==10088== definitely lost: 0 bytes in 0 blocks
==10088== indirectly lost: 0 bytes in 0 blocks
==10088== possibly lost: 0 bytes in 0 blocks
==10088== still reachable: 28 bytes in 1 blocks
==10088== suppressed: 0 bytes in 0 blocks
Currently a test suite here fails due to this leak.
When setting 'addrinfo' to NULL after freeaddrinfo(), valgrind reports the leak as
'definitely lost' and returns with non-zero, thus the breakage of the test suite.
Regards, Tim

.
[ Aurelien Jarno ]
* Update from upstream stable branch:
- Fix a memory leak in the resolver. Closes: #818178.
* debian/patches/localedata/fr_CA-first_weekday.diff: drop. Closes:
#769051.
* debian/rules, debian/rules.d/build.mk: move the C.UTF-8 locale and
locales-all generation to a separate target instead of building them
in the build_libc target.
* debian/control.in/main, debian/rules, debian/rules.d/build.mk: make sure
to use the just built localedef when building locales. When
cross-compiling use the system localedef with the correct endianness and
build-depends on the correct version.
