The problem was that the 'defdname' field of res_state structure was not properly initialized in __res_vinit(). This field is used to store the default domain name, which is normally build from calling gethostname() (see line 549 of res_init.c). Unfortunately, in the typical Android case, gethostname() returns an error (the hostname is configured) and a random stack string is used later to build the DNS search list (see lines 556+ in res_init.c) For the sake of illustration, let's say the search list is set to a random value like 'xWLK'. The end result is that when trying to result an unknown domain name (e.g. 'www.ptn'), the query fails then the resolver tries to make a new query with the DNS search list path(s) appended (e.g. 'www.ptn.xWLK'). The patch simply initializes 'defdname' to an empty string to avoid this when the net.dns.search system property is not set. Also contains whitespace/formatting fixes

Bionic ChangeLog:
|
|
-----------------
|
|
|
|
Differences between current and Android 2.1:
|
|
|
|
- Add support for SH-4 CPU architecture !
|
|
|
|
- __atomic_swap(): use LDREX/STREX CPU instructions on ARMv6 and higher.
|
|
|
|
- <arpa/telnet.h>: New header (declarations only, no implementation).
|
|
|
|
- <err.h>: New header + implementation. GLibc compatibility.
|
|
|
|
- <warn.h>: New header + implementation. GLibc compatibility.
|
|
|
|
- <fts.h>: New header + implementation.
|
|
|
|
- <mntent.h>: Add missing <stdio.h> include.
|
|
|
|
- <regex.h>: New header + implementation.
|
|
|
|
- <signal.h>: Added killpg()
|
|
|
|
- <stdint.h>: Allow 64-bit type declarations on C99 builds.
|
|
|
|
- <stdio.h>: Add fdprintf() and vfdprintf(). Note that GLibc provides
|
|
the confusing 'dprintf' and 'vdprintf()' functions instead.
|
|
|
|
- <stdlib.h>: Fix ptsname_r(): the return type is int instead of char*.
|
|
The mistake comes from a GLibc man page bug (the man page listed a return
|
|
type of char*, while the implementation used int. Fixed in late 2009 only).
|
|
The Bionic implementation was incorrect. Technically, this is an ABI
|
|
breakage, but code that used this function probably never worked or
|
|
compiled properly anyway.
|
|
|
|
- <strings.h>: Add missing <sys/types.h> include.
|
|
|
|
- <sys/queue.h>: Added new header (no implementation - macro templates).
|
|
|
|
- <sys/resource.h>: Add rlim_t proper definition.
|
|
|
|
- <time64.h>: Add missing C++ header inclusion guards.
|
|
|
|
- <unistd.h>: Add getusershell(), setusershell() and endusershell(), though
|
|
implementation are bogus. GLibc compatibility.
|
|
|
|
- <wchar.h>: Add mbstowcs() and wcstombs()
|
|
|
|
- add clone() implementation for ARM (x86 and SH-4 not working yet).
|
|
|
|
- <sys/epoll.h>: <sys/system_properties.h>: Add missing C++ inclusion guards
|
|
|
|
- fix getpwnam() and getpwgrp() to accept "app_0" as a valid user name.
|
|
|
|
- fix sem_trywait() to return -1 and set errno to EAGAIN, instead of
|
|
returning EAGAIN directly.
|
|
|
|
- fix sem_post() to wake up multiple threads when called rapidly in
|
|
succession.
|
|
|
|
- DNS: partial implementation of RFC3484 (rule 1, 2, 5, 6, 8, 10 and
|
|
modified rule 9), for better address selection/sorting.
|
|
In the process, removed code that was previously used for "sortlist"
|
|
in /etc/resolv.conf. (resolv.conf is already ignored, so the latter
|
|
is a no-op for actual functionality.)
|
|
|
|
- fix pthread_sigmask() to properly return an error code without touching
|
|
errno. Previous implementation returned -1 on error, setting errno, which
|
|
is not Posix compliant.
|
|
|
|
- add sigaltstack() implementation for ARM.
|
|
|
|
- <time.h>: Properly implement the 'timezone' and 'daylight' global variables
|
|
(they were not defined previously, though declared in the header).
|
|
|
|
- <time.h>: Fix timezone management implementation to properly update
|
|
'tm_gmtoff' field in 'struct tm' structure.
|
|
|
|
- DNS: get rid of spurious random DNS queries when trying to resolve
|
|
an unknown domain name. Due to an initialization bug, a random DNS search
|
|
list was generated for each thread is net.dns.search is not defined.
|
|
|
|
-------------------------------------------------------------------------------
|
|
Differences between Android 2.1 and 2.0.1:
|
|
|
|
- zoneinfo: updated data tables to version 2009s
|
|
|
|
|
|
-------------------------------------------------------------------------------
|
|
Differences between Android 2.0.1 and 2.0:
|
|
|
|
- abort(): ARM-specific hack to preserve the 'lr' register when abort()
|
|
is called (GCC does not preserve it by default since it thinks that
|
|
abort() never returns). This improves stack traces considerably.
|
|
|
|
|
|
-------------------------------------------------------------------------------
|
|
Differences between Android 2.0 and 1.6:
|
|
|
|
- memcmp(), memcpy(): ARMv7 optimized versions.
|
|
|
|
- pthread_mutexattr_setpshared(): implementation will not return ENOTSUP
|
|
if PTHREAD_PROCESS_SHARED is used, because our Mutex implementation can
|
|
work across multiple processes.
|
|
|
|
*HOWEVER* it does not use "robust futexes" which means that held mutexes
|
|
*are not* automatically released by the kernel when the owner process
|
|
crashes or exits. This is only done to simplify communication between
|
|
two always-live system processes, DO NOT USE THIS IN APPLICATIONS !
|
|
|
|
- pthread_mutex_lock_timeout_np(): New Android-specific function to
|
|
perform a timed lock (). In case of timeout, it returns EBUSY.
|
|
|
|
- pthread_cond_timedwait_monotonic_np(): Same as pthread_cond_timedwait()
|
|
but uses the monotonic clock(). Android-specific.
|
|
|
|
- pthread_cond_timedwait_relative_np(): Same as pthread_cond_timedwait()
|
|
but uses a relative timeout instead. Android-specific.
|
|
|
|
- <netinet/in.h>: Now includes <netinet/in6.h>.
|
|
|
|
- <netinet/in6.h>: Added IPV6_JOIN_GROUP, IPV6_LEAVE_GROUP, IN6ADDR_ANY_INIT
|
|
and ipv6mr_interface definitions.
|
|
|
|
- <time.h>:
|
|
* Add missing tzset() declaration.
|
|
* Add Android-specific strftime_tz().
|
|
|
|
- getaddrinfo():
|
|
Only perform IPv6 lookup for AF_UNSPEC if we have IPv6 connectivity.
|
|
This saves one DNS query per lookup on non-IPv6 systems.
|
|
|
|
- mktime(): Fix an infinite loop problen that appeared when switching to
|
|
GCC 4.4.0.
|
|
|
|
- strftime(): fix incorrect handling of dates > 2038 due to 64-bit issue
|
|
in original code.
|
|
|
|
-------------------------------------------------------------------------------
|
|
Differences between Android 1.6 and 1.5:
|
|
|
|
- C runtime: Fix runtime initialization to be called before any static C++
|
|
constructors. This allows these to use pthread functions properly.
|
|
|
|
- __aeabi_atexit(): Fix implementation to properly call C++ static destructors
|
|
when the program exits (or when a shared library is unloaded).
|
|
|
|
- <sys/stat.h>: added GLibc compatibility macros definitions:
|
|
|
|
#define st_atimensec st_atime_nsec
|
|
#define st_mtimensec st_mtime_nsec
|
|
#define st_ctimensec st_ctime_nsec
|
|
|
|
- getaddrinfo(): implementation will now allow numeric ports if ai_socktype is
|
|
set to ANY. This is to match the GLibc behaviour.
|
|
|
|
- getservent(): and getservent_r() incorrectly returned the port in host-endian
|
|
order in the s_port field. It now returns it in big-endian order.
|
|
|
|
- DNS: Allow underscore in the middle of DNS labels. While not really
|
|
standard, this extension is needed for some VPN configurations and is
|
|
supported by other operating systems.
|
|
|
|
- DNS: Support for DNS domain search lists through the new net.dns.search
|
|
system property. The corresponding value must be a space-separated list of
|
|
domain suffixes.
