[PATCH] inet/resolv: use h_errno from __dns_lookup instead of a static error code

by Wenzel, Alexander

When trying to resolve a hostname by getaddrinfo() using some specific settings, it will always return -EAI_NONAME (Name or service not known). To reproduce this behavior, you need to request an IPv6 address with the additional v4mapped flag set from an non IPv6 capable hostname. If you choose a IPv6 capable hostname like google.com, everything works fine. To go a bit deeper, e.g. gethostbyname2_r will always return HOST_NOT_FOUND, which in our example is wrong. The hostname is existent but doesn't provide an IPv6 address. So NO_DATA would be correct, which is present in the h_errno variable set by __dns_lookup. ---- 8< ---- int ret; struct addrinfo* result; struct addrinfo hints; memset(&hints, 0, sizeof(struct addrinfo)); hints.ai_family = AF_INET6; hints.ai_flags = AI_V4MAPPED; ret = getaddrinfo("test.com", NULL, &hints, &result); printf("getaddrinfo(): %i", ret); ---- 8< ---- Signed-off-by: Alexander Wenzel <alexander.wenzel(a)qsc.de> --- libc/inet/resolv.c | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-) diff --git a/libc/inet/resolv.c b/libc/inet/resolv.c index e3ad513..176fd78 100644 --- a/libc/inet/resolv.c +++ b/libc/inet/resolv.c @@ -2118,7 +2118,7 @@ int gethostbyname_r(const char *name, a.add_count = 0; packet_len = __dns_lookup(name, T_A, &packet, &a); if (packet_len < 0) { - *h_errnop = HOST_NOT_FOUND; + *h_errnop = h_errno; DPRINTF("__dns_lookup returned < 0\n"); return TRY_AGAIN; } @@ -2316,7 +2316,7 @@ int gethostbyname2_r(const char *name, a.add_count = 0; packet_len = __dns_lookup(name, T_AAAA, &packet, &a); if (packet_len < 0) { - *h_errnop = HOST_NOT_FOUND; + *h_errnop = h_errno; DPRINTF("__dns_lookup returned < 0\n"); return TRY_AGAIN; } @@ -2504,7 +2504,7 @@ int gethostbyaddr_r(const void *addr, socklen_t addrlen, /* Hmm why we memset(a) to zeros only once? */ packet_len = __dns_lookup(buf, T_PTR, &packet, &a); if (packet_len < 0) { - *h_errnop = HOST_NOT_FOUND; + *h_errnop = h_errno; return TRY_AGAIN; } -- 2.1.4

[PATCH] sysconf: Support _SC_(AV)?PHYS_PAGES.

by Nicolas Cavallari

Do it by following the trail of the existing commented code, which implemented it by calling get_phys_pages() and get_avphys_pages(). This patch implements these two functions, which are also glibc extensions. Some program/libraries (e.g. libuv) assumes that sysconf(_SC_PHYS_PAGES) works on linux and never check for -1, thus they report an insane amount of memory.

tst-ethers test failing

by Eugeniy Paltsev

Hello, I'm running uclibc-1.0.15 testsuite on ARC and see "tst-ethers" fails. From what I may see "tst-ethers" test requires /etc/ethers to exist and to have host "teeth", otherwise it fails. This test passed on ARC and other architectures, as I can see at http:/ /tests.embedded-test.org/uClibc-ng/1.0.15/ , so I'm wondering if there's some dependency we need to have in place for this test to pass successfully? Or, maybe, we should create /etc/ethers file with host "teeth" at the beginning of the test, if they does not exists? --- Best regards, Paltsev Eugeniy
