So far accept4 was only supported on archs using socketcall for x86.
This patch adds support for the remaining archs.

|
|
The latest stratcliff extension exposed a bug in the IA-64 memchr which
uses non-speculative loads to prefetch data. Change the code to use
speculative loads with appropriate fixup. Fixes BZ 10162.
|
|
|
|
The ____longjmp_chk functions on x86 and x86-64 were placed in .rodata.str1.1.
|
|
|
|
This definition was meant to be removed before the checkin. It was
used in the development.
|
|
The header had the old name (paccept).

|
|
|
|
|
Following the previous changes for x86 and x86-64.

There are two issues with the forced loop exit in the nscd lookup:
1. the estimate of the entry size isn't pessimistic enough for all
databases, resulting potentially is too early exits
2. the combination of 64-bit process and 32-bit nscd would lead to
rejecting valid records in the database.
|
|
The unrelated function __libc_cleanup_routine should not be in
this file. Move it into its own file.
|
|
Unify all three places where we enable async cancellation for
syscalls. Optimize a bit.
|
|
We don't update the RPC sources from the original tarball anymore.
No need to ignore that directory.
|

|
This fixes BZ #10159. The stdlib.h definition was out of date.
|
|
The move to nscd-client.h was only needed for some interim version
of the patch. The final version doesn't need it. Undo the change.
|
|
The patch to bound the search in the nscd caches used a wrong exit
condition. Fixed now.
|
|
Needed to allow overwriting architectures init.c in csu and nptl
individually. Fixes BZ #9924.

We can compute an absolute maximum for the number of elements which
can fit into the currently mapped database. Stop after that many
iterations.
|
|
The nscd database mapped in processes can change at any time. We
have to be more vigilant when it comes to using that memory. Test
the data entries are valid in their entire size, don't read data
again from memory once we verified it, and make sure the trailing
pointer is not going off the deep end.

Due to a pasto the fallocate64 interface, introduced in glibc 2.10,
isn't exported for 32-bit Linux platforms. It is too late for this
now so exported them for glibc 2.11.

Because we are not shutting down the other threads first another
thread might work on a query before the process shuts down. In this
case the now uninitialized libselinux and libaudit might be used.
Just don't free the resources. It's not necessary anyway because
the process is about to terminate.
|
|
The bits tested to decide when to delay the return when switching
off async cancel mode were wrong. Fix that. Also close a race
condition in pthread_cancel where the bit indicating the cancellation
is unconditionally set even if the cancel type might have changed.

ChangeLog

|
|
|
If longjmp restores the stack frame to an address which is beyond
the stack frame at the time of the longjmp call it would install
an uninitialized stack frame. If compiled with _FORTIFY_SOURCE
defined, longjmp will now bail out in this situation.

When disabling async cancellation we cannot return from the function
call if the thread is canceled. This happens when the cancel bits
have been set before async cancel is disabled but the signal hasn't
been sent/received yet. Delay for as long as necessary since
otherwise the signal might be received in an unsafe context.

Add a text program, built to run on the host, to check all newly
built DSOs for executable stacks and fail if the stack information
is missing or indicates executable stacks.

[BZ #10118]
* Makeconfig (+asflags): New variable based upon ASFLAG or
asflags-cpu.
(ASFLAGS): Add override to set ASFLAGS to +asflags.
* config.make.in (asflags-cpu): Add variable based upon
@libc_cv_cc_submachine@ to propagate -mcpu=CPU from --with-cpu=CPU to
the assembler.
* sysdeps/unix/sysv/linux/powerpc/powerpc32/power6/fpu/setcontext.S:
Remove unneeded file now that the assembler emits _ARCH_PWR6 and
recognizes power6 instruction set due to passing -mcpu=power6 from
--with-cpu=power6 when compiling .S files.
