* nptl: Fix libpthread build when UCLIBC_LINUX_SPECIFIC is disabledCarmelo Amoroso2010-09-202-2/+7
| | | | | | | | | | | | | | | | | NPTL library needs both madvise and statfs symbols, that are guarded by UCLIBC_LINUX_SPECIFIC option. This fix provides these symbols too when NPTL is used, indipendently by UCLIBC_LINUX_SPECIFIC choice. Otherwise libpthread link fails as below: LD libpthread-0.9.32-git.so libpthread/nptl/libpthread_so.a(pthread_create.oS): In function `__free_tcb': pthread_create.c:(.text+0x1184): undefined reference to `madvise' libpthread/nptl/libpthread_so.a(sem_open.oS): In function `__where_is_shmfs': sem_open.c:(.text+0x764): undefined reference to `statfs' collect2: ld returned 1 exit status make: *** [lib/libpthread.so] Error 1 Signed-off-by: Carmelo Amoroso <carmelo.amoroso@st.com>
* libc: Handle cancellation in non multiplexed socket callsCarmelo Amoroso2010-09-171-17/+122
| | | | | | | | | | For those archs that provide non multiplexed socket calls it possible to implement the lib C wrappers without calling the multi-purpose __socketcall. For a subset of these functions that are cancellation point, it needs to correctly handle cancellation.

* sh: update the memcpy adding a new loop with aggressive prefetchingSalvatore Cro2010-09-151-21/+107
| | | | | | | | | | | | | | | | After exploring different prefetch distance-degree combinations in this new update of the memcpy function, a new loop has been added for moving many cache lines with an aggressive prefetching schema. Prefetch has been removed when move few cache line aligned blocks. As final result, this memcpy gives us the same performances for small sizes (we already had!) and better numbers for big copies. In case of SH4-300 CPU Series, benchmarks show a gain of ~20% for sizes from 4KiB to 256KiB. In case of the SH4-200, there is a gain of ~40% for sizes bigger than 32KiB.

* sh: move data without fetching cache block within the memsetSalvatore Cro2010-09-151-28/+34
| | | | | | | | | | | | | | | | | | | | | | | With this patch the movca.l instruction is used within the memset. The current memset implementation only uses the FPU and there is an real gain for all the sizes. Adding the movca.l instruction numbers always are better than the generic code. There is a big gain for size greater than 64 KiB but number are worst for 4-32KiB sizes compared with the implementation without movca.l.

* libc: Provide both getpgid and __getpgid symbolsCarmelo Amoroso2010-08-311-1/+4
| | | | | | | | | | 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).

* Fix resolver broken in NPTL buildTimo Teräs2010-08-281-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Fix ctime() standard compliance bugDavid A Ramos2010-07-271-0/+1
| | | | | | | | | | | | | | | | | | | | | 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>
