2010-09-15libc: Fix cancellation handling in some C functionsSalvatore Cro
According to POSIX.1-2008 standard, the following syscalls shall be cancellation points : waitid, sleep, fdatasync, ppoll. Further, if generic syscall is not available and stubs are configured, provide the stub implementation for function.

2010-08-31libc: Provide both getpgid and __getpgid symbolsCarmelo Amoroso
Indeed unistd.h header does export '__getpgid' by default, while uClibc provide only 'getpgid' implementation. The 'getpgid' symbol is exported by standard header if __USE_XOPEN_EXTENDED is defined. This patch alignes uClibc implementation with standard header (matching with glibc behaviour). Signed-off-by: Carmelo Amoroso <carmelo.amoroso@st.com>
2010-08-28Fix resolver broken in NPTL buildTimo Teräs
The combination of commit aab4df0fb51660300559f5f29290709db2f7bfee resolv.c: add support for per thread res_state commit cca45baf8353d1e338d232f5bdb2d1d6b357f1da /etc/resolv.conf: support "timeout:n" and "attempts:n" options .. and NPTL results in broken resolver in very annoying ways. Now, it seems that most of the uclibc code does not work well if res_state is TLS variable. Technically, this is the correct thing to do since this gives proper per-thread resolving behavior, and it also makes the config options overridable per thread. This probably what apps expect as glibc does it too. But alas, most places use _res to sync up static global variables which results in breakage. It gets more or less randomly selected which threads options get applied. Also in case of multiple servers it looks like the retry logic is shared between all threads, e.g. two concurrent resolutions can make other resolvers skip nameservers due to shared "last_ns_num". And finally the timeout/attempts commit breaks the accumulated stuff horribly. What happens is: 1. multithreaded application startups, initializes resolver, resolves things just fine 2. resolv.conf gets changed, application calls res_init after res_init uclibc will call res_sync on all resolver functions to refresh globals from the TLS variable _res 3. res_init was called only in one thread, so other thread's _res contains all zeroes (yes, this is correct app usage: res_init should be called only from one thread) 4. threads not calling res_init get broken resolver due to timeout being set to zero Now, one proper solution would be to: 1. make __open_nameservers return the configuration options 2. pass the config options struct to res_sync_func so it can do the proper overrides from per-thread _res 3. remove the related globals and use locally config options from __open_nameservers But technically, the correct thing (as in glibc does this) is: - res_init increases global "res_init timestamp" - use _res (or pointer within there) for resolver retries etc. get proper per-thread behavior - resolvers functions call "maybe_init" which reinitialize the TLS'ed resolver state (e.g. reload resolv.conf) if their res_init timestamp is out dated As an immediate emergency kludge fix, the following might do: resolv: fix options handling for TLS _res If _res is in TLS (NPTL), it might not get initialized.

2010-08-06config parser: fix memory corruptionTimo Teräs
fgets will happily write over allocated area limits. Adjusted the buffer size according to how much is already read. Also increase the maximum default line length, as 80 is slightly small. It might be better if bb_get_chunk_with_continuation would reallocate the line buffer if it was not user given.

2010-07-28Immediately try next nameserver on recv() failureIngo van Lil
If there is a problem communicating with a nameserver the __dns_lookup() function will not immediately advance to the next nameserver but instead continue waiting until the timeout expires. This will cause a 30 second delay even if no nameserver is configured in resolv.conf and no DNS is running on localhost.

2010-07-27new helper funcs for alloca/malloc with mmu/nommuMike Frysinger
The rpc rcmd code has some ugly ifdef mazes to handle mmu/nommu differences just to select alloca or malloc. Unify those with some helper macros in a new header, and then convert the rcmd code over to it. This is all geared towards fixing the getdents helper functions which only use alloca() atm. Now that we have helper functions, convert the getdents functions over too. Signed-off-by: Mike Frysinger <vapier@gentoo.org> Reviewed-by: Steven J. Magnani <steve@digidescorp.com>

2010-07-27Fix ctime() standard compliance bugDavid A Ramos
fixes issue2209: ctime() was updated in 0.9.31 to call localtime_r() instead of localtime() to avoid using a static buffer. Unfortunately, this change replaces the static buffer (which is zeroed out on initialization) with an uninitialized local buffer. In the common case, this has no effect. However, with a sufficiently large time_t value, the value returned differs from that returned by asctime(localtime(t)), and thus violates the ANSI/ISO standard. An example input is (on a 64-bit machine): time_t t = 0x7ffffffffff6c600; Signed-off-by: Bernhard Reutner-Fischer <rep.dot.nop@gmail.com>
