08b51e2c09 Implement the "abort" stub in assembly for ARM.
So that we can always get the full stack trace regardless of gcc's handling
of the "noreturn" attribute associated with abort().

d1860ad8dd fnmatch.c: Update to version in OpenBSD HEAD
Upgrade fnmatch.c from OpenBSD version 1.13 to 1.16.
This is needed primarily to address CVE-2011-0419.

This is a straight copy from upstream's version at
http://www.openbsd.org/cgi-bin/cvsweb/src/lib/libc/gen/fnmatch.c and
incorporates the following changes:

Revision 1.16:
New fnmatch(3) implementation which is not recursive.
Written and provided under BSD licence by William A. Rowe Jr.
Originally released in Apache APR-1.4.5.
Merged class matching code from r1.14 and PATH_MAX check from r1.15.
ok miod millert

Revision 1.15:
Put a limit on recursion during matching, and reject input of size greater
or equal PATH_MAX. Based on similar fix made in NetBSD.
ok miod@ millert@

Revision 1.14:
POSIX character class support for fnmatch(3) and glob(3).  OK deraadt@

Version 1.14 introduced charclasses.h, which we copy unmodified
from upstream version 1.1.
http://www.openbsd.org/cgi-bin/cvsweb/src/lib/libc/gen/charclass.h

a37f372973 readdir: fix interface to kernel getdents64 function
Issue:
  The kernel will pad the entry->d_reclen in a getdents64 call to a
  long-word boundary.  For very long records, this could exceed the
  size of a struct dirent. The mismatch in the size was causing error
  paranoid checking code in bionic to fail... thus causing an early
  "end" when reading the dirent structures from the kernel buffer.

Test:
 ls
 mkdir abcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstu
 ls

3884bfe966 libc: popen: work around data corruption
vfork() would not save the registers that the parent would expect
to have restored after execl() completed.
Specially that execl() would call execve() underneath, further messing
up the stack of the parent.
To avoid that, we fork() for now. Later we will revisit and cleanup
vfork()+execve() to actually have vfork() store all the register
that the parent expects to see, and not those left by execve().

In the original code, looking at the registers just before the call to
popen(), and after the call showed that r7 would get clobbered.
This would leave the caller with an invalid pointer, leading to all
kinds of data corruptions.
execve() is simpler that execl() in this case.

is not traceable in the git history, but it's most likely due to some old
toolchain or emulator problem.

95d751feac libc: Add ftruncate64 and improve 64-bit parameter syscall handling.
This patch improves the handling of 64-bit parameters in syscalls on ARM.
The ARM EABI mandates that 64-bit quantities be passed in even/odd register
pairs, which requires special treatment.

This allows us to simplify our implementations of pread() and pwrite()
and remove the C stubs for pread64() and pwrite64().

Also add ftruncate64() to <unistd.h>

b44fcd6e8f Fix for incorrect reply from sysconf(_SC_NPROCESSORS_ONLN)
When calling sysconf with _SC_NPROCESSORS_ONLN, the value one (1) was
returned on systems with two or more cores, since '/proc/stat' was
incorrectly parsed.

The function line_parser_getc (LineParser* p) read 128 characters of
input for each invocation.

The proper and probably aimed for behavior is to read 128 characters
at the first call, then for each subsequent call only return the next
buffered character until a new read is needed and only then read
another 128 characters.

Due to a flipped comparison between the two variables in_len and
in_pos that track the number of bytes of data read into the input
buffer and how much of it has been parsed, a new group of 128
characters were read at almost every call to line_parser_getc,
overwriting the still unhandled bytes from the previous call to
read. This caused the lines to be read to be sampled more than parsed.

d378c68d74 Fix spurious DNS lookups in the C library.
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
