Better glibc compatibility for getline/getdelim:
- Tolerate applications that pass a NULL pointer for the buffer and
claim that the capacity of the buffer is nonzero.
- If an application passes in a non-NULL buffer pointer and claims the
buffer has zero capacity, we should free (well, realloc) it
anyway. It could have been obtained from malloc(0), so failing to
free it would be a small memory leak.
Fix a regression that was introduced in r191882.
I changed login_tty() to only work when the application is not a session
leader yet. This works fine for applications in the base system, but it
turns out various applications call this function after daemonizing,
which means they already use their own session.
If setsid() fails, just call tcsetsid() on the current session.
tcsetsid() will already perform proper security checks.

Fix a bug in gzipfs that prevented lseek() from working and add lseek()
support to bzip2fs. This fixes problems with loading compressed amd64
kernel modules containing debug symbols.
Reset path name back to original correctly in fts_build() when
FTS_NOCHDIR option is used. fts_build() could strip a trailing slash
from path name in post-order visit if a path pointing to an empty

Properly support -fPIE by linking PIE binaries with specially-built
Scrt1.o instead of crt1.o, since the later is built as non-PIC.
Separate i386-elf crt1.c into the pure assembler part and C code,
supplying all data extracted by assembler stub as explicit parameters.
Hide and localize _start1 symbol used as an interface between asm and

Add an internal _once() method. This works identical to pthread_once(3)
with the additional property that it is safe for routines in libc to use
in both single-threaded and multi-threaded processes. Multi-threaded
processes use the pthread_once() implementation from the threading library
while single-threaded processes use a simplified "stub" version internal
to libc.
Add a new errno, ENOTCAPABLE, to be returned when a process requests an
operation on a file descriptor that is not authorized by the descriptor's
capability flags.

Update to BIND 9.6.1-P2. The vulnerability this is designed to fix is
related to DNSSEC validation on a resolving name server that allows
access to untrusted users. If your system does not fall into all 3 of

Not all Intel Core (TM) CPUs implement PMC_CLASS_IAF fixed-function
counters. For such CPUs, use an alternate mapping of convenience
names to events supported by PMC_CLASS_IAP programmable counters.
Add two new fcntls to enable/disable read-ahead:
- F_READAHEAD: specify the amount for sequential access. The amount is
specified in bytes and is rounded up to nearest block size.
- F_RDAHEAD: Darwin compatible version that use 128KB as the sequential
access size.
A third argument of zero disables the read-ahead behavior.
Please note that the read-ahead amount is also constrainted by sysctl
variable, vfs.read_max, which may need to be raised in order to better
utilize this feature.
Thanks Igor Sysoev for proposing the feature and submitting the original
version, and kib@ for his valuable comments.
The fd_mask type is an unsigned long, not an int, so treat the mask as a
long instead of an int when examining the results of select() to look for
RPC requests. Previously this routine would ignore RPC requests to sockets
whose file descriptor mod 64 was greater than 31 on a 64-bit platform.
* retry various system calls on EINTR
* retry the rest after a short read (common if there is more than about 1K

work fully in threaded programs, they will need to be careful with wait
functions)
