It's even no longer required for non-ported ppc64
architecture. Sync with GNU C library.
This simplify the macros in include/libc-symbols.h.
|
|
uClibc doesn't define signal info for the SIGSYS signal which is issued
in case of hitting a syscall prohibited by seccomp.
This is sad as it makes debugging seccomp filter policies impossible on
some architectures (at least ARM and PowerPC, maybe also others) which
do not coincidentally set si_value.sival_int as the syscall number.
To fix this, import the definitions and macros needed from glibc.

The sparc64/sparcv9 code is incomplete. Furthermore there is
no real embedded hardware for sparc64 available, so better remove
it until someone comes up with a complete port.

Add "__pid_t _tid" member which is used for some packages, like rt-test
for instance, which fails with an error like this one:

member named '_tid'

As in timerfd.h, eventfd.h needs arch-specific definition files.
alpha, mips and sparc needs separate file, all the other arch
will use common definition.
This problem is already fixed in glibc.
Also sanitize and provide bits for hppa.
Make sure not to install the new bits/eventfd unless eventfd support is
enabled.

The reason truncate64 takes 4 args on some arches is that their ABI
requires 64bit values to be aligned on register pair boundaries.
Since this alignment affects more than just truncate64, rename the
define to properly document its purpose. This also allows us to
expand it to the other impacted syscalls (which will be done in a
follow up commit).

This drops __signed, __volatile, and __const. Only the latter was
used in the code base, and for uClibc, not consistently. Much of
the code used plain "const" which meant "__const" was useless.
Really, the point of this is to stay in sync with what glibc did.

Linux 3.4 added __kernel_long_t and __kernel_ulong_t and various
exported header files were updated to use these new types. Add the
definitions for __kernel_long_t and __kernel_ulong_t to the relevant
kernel_types.h headers.
This change was automated with the following scriptlet
git grep --name-only 'typedef.*__kernel_old_dev_t' \
| xargs sed -i '/typedef.*__kernel_old_dev_t/ a\
typedef long\t\t__kernel_long_t;\
typedef unsigned long\t__kernel_ulong_t;'
Whitespace in arm, avr32, hppa, sparc was then manually fixed up.

Here's a cleaned up patch which should get the whitespace right. I'm a
bit iffy about the sparc changes they make sense to me but it's not a
platform I have access to.
I can break this up per arch or per maintainer if requested.

glibc has split off the arch-specific flag definitions (like
SFD_NONBLOCK) into <arch>/bits/signalfd.h, so that there are no longer
multiple redundant copies of the entire header file. We will adopt the
same scheme in uClibc.
Special cases are included for: alpha mips sparc
hppa was omitted because it has not been updated in glibc.
All others use the common definition.

Fill out the stat structure so that the nanosecond resolution support is
always available. There is a small code size increase for a few ports
(three additional assignments in xstatconv), but otherwise everything
should remain the same.
While we're here, punt __old_kernel_stat from the few headers that still
define it as it is unused in uClibc and causes compile errors after these
nanosecond changes.
