* malloc-standard: synchronize on forkTimo Teräs2011-12-231-0/+17
| | | | | | | | Otherwise other threads can leave malloc state locked, and the child will hang indefinitely if it tries to malloc something. Signed-off-by: Timo Teräs <timo.teras@iki.fi> Signed-off-by: Natanael Copa <ncopa@alpinelinux.org>

* nommu: use MAP_UNINITIALIZE for mallocsMike Frysinger2009-11-231-1/+1
| | | | | | | | | Now that the kernel supports MAP_UNINITIALIZE, have the malloc places use it to get real uninitialized memory on no-mmu systems. This avoids a lot of normally useless overhead involved in zeroing out all of the memory (sometimes multiple times). Signed-off-by: Mike Frysinger <vapier@gentoo.org>

* Last portion of libc_hidden_proto removal.Denis Vlasenko2008-11-204-4/+4
| | | | | Appears to build fine (several .configs tried)

* libc_hidden_proto removal, just a few functionsDenis Vlasenko2008-11-181-1/+1

* Moving libc_hidden_proto's into #ifdef UCLIBC_INTERNAL blockDenis Vlasenko2008-05-192-2/+2
| | | | | | | | | in string.h and strings.h. This caught unguarded string ops in libc/inet/ethers.c __ether_line_w() function. I will wait for fallout reports for a week or so, then continue converting more libc_hidden_proto's.

* Major cleanup of internal mutex locking. Be more consistant in how we doEric Andersen2006-12-078-73/+98
| | | | | | | things, and avoid potential deadlocks caused when a thread holding a uClibc internal lock get canceled and terminates without releasing the lock. This change also provides a single place, bits/uClibc_mutex.h, for thread libraries to modify to change all instances of internal locking.
