2012-10-02libc/sysdeps: add __kernel_long and __kernel_ulongChris Packham
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. Signed-off-by: Chris Packham <chris.packham@alliedtelesis.co.nz> -- 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. libc/sysdeps/linux/alpha/bits/kernel_types.h | 2 ++ libc/sysdeps/linux/arm/bits/kernel_types.h | 2 ++ libc/sysdeps/linux/avr32/bits/kernel_types.h | 2 ++ libc/sysdeps/linux/bfin/bits/kernel_types.h | 2 ++ libc/sysdeps/linux/c6x/bits/kernel_types.h | 2 ++ libc/sysdeps/linux/cris/bits/kernel_types.h | 2 ++ libc/sysdeps/linux/e1/bits/kernel_types.h | 2 ++ libc/sysdeps/linux/h8300/bits/kernel_types.h | 2 ++ libc/sysdeps/linux/hppa/bits/kernel_types.h | 2 ++ libc/sysdeps/linux/i386/bits/kernel_types.h | 2 ++ libc/sysdeps/linux/ia64/bits/kernel_types.h | 2 ++ libc/sysdeps/linux/m68k/bits/kernel_types.h | 2 ++ libc/sysdeps/linux/microblaze/bits/kernel_types.h | 2 ++ libc/sysdeps/linux/mips/bits/kernel_types.h | 4 ++++ libc/sysdeps/linux/nios2/bits/kernel_types.h | 2 ++ libc/sysdeps/linux/powerpc/bits/kernel_types.h | 4 ++++ libc/sysdeps/linux/sh/bits/kernel_types.h | 2 ++ libc/sysdeps/linux/sh64/bits/kernel_types.h | 2 ++ libc/sysdeps/linux/sparc/bits/kernel_types.h | 4 ++++ libc/sysdeps/linux/v850/bits/kernel_types.h | 2 ++ libc/sysdeps/linux/x86_64/bits/kernel_types.h | 2 ++ libc/sysdeps/linux/xtensa/bits/kernel_types.h | 2 ++ 22 files changed, 50 insertions(+) Signed-off-by: Bernhard Reutner-Fischer <rep.dot.nop@gmail.com>

2012-06-06MIPS: Use $a0 instead of $v0 for __syscall_error() argumentKevin Cernekee
$a0 is saved across _dl_runtime_resolve(); $v0 is not. Unfortunately, __syscall_error() uses $v0 for its argument, not $a0 as is the MIPS ABI standard. This means that if lazy binding was used for __syscall_error(), the errno value in $v0 could get corrupted. The problem can be easily seen in testcases where syscalls in librt fail; when librt tries to call __syscall_error() in libc, the argument gets lost and errno gets set to a bogus value: # ./tst-mqueue1 ; echo $? mq_receive on O_WRONLY mqd_t did not fail with EBADF: Unknown error 2004684208 1 # ./tst-mqueue2 ; echo $? mq_timedreceive with too small msg_len did not fail with EMSGSIZE: Unknown error 1997360560 1 # ./tst-mqueue4 ; echo $? mq_timedsend did not fail with ETIMEDOUT: Unknown error 2008747440 1 When _dl_runtime_resolve() was taken out of the equation, the same test cases passed: # LD_BIND_NOW=y ./tst-mqueue1 ; echo $? 0 # LD_BIND_NOW=y ./tst-mqueue2 ; echo $? 0 # LD_BIND_NOW=y ./tst-mqueue4 ; echo $? 0 Changing __syscall_error() to look at $a0 instead of $v0 fixed the problem. (Note that there is also a "__syscall_error.c" file which presumably uses the standard C calling conventions, but I do not think it is used on MIPS.)

2010-10-27mips: fix errno setting after syscallAlexander Gordeev
If there was an error during syscall then after it's completion a3 register holds a non-zero value and v0 holds an actual error code which should be saved in errno. This can be achieved by calling __syscall_error with the value from v0 as a parameter. So this value should be stored in a0, but the appropriate assembly instructions are missing. Fixed this now by adding "move a0, v0". I think it was once fixed by 58c5f8ba4cdf62342d05a546d15404cbbb3c4e07 but then something went wrong. Again...

2010-04-27MIPS: restore INLINE_SYSCALL macroGabor Juhos
The MIPS specific INLINE_SYSCALL macro has been renamed to INLINE_SYSCALL_NCS with: 763bbf9e9a27426c9be8322dca5ddf2cb4dbc464 syscall: unify part 2: NCS variety Declare common NCS (non-constant syscall) variants and convert the existing ports over to this. This change breaks system calls. The code generated with using of the new macro does not obey the restartable syscall convention used by the linux kernel. When it tries to restart the syscall the errno value is not being replaced by the syscall number. This causes weird behaviour of the 'ping' command in busybox for example: root@OpenWrt:/# ping 192.168.1.254 PING 192.168.1.254 (192.168.1.254): 56 data bytes 64 bytes from 192.168.1.254: seq=0 ttl=128 time=6.292 ms ping: recvfrom: Function not implemented 64 bytes from 192.168.1.254: seq=1 ttl=128 time=0.719 ms ping: recvfrom: Function not implemented 64 bytes from 192.168.1.254: seq=2 ttl=128 time=0.489 ms ping: recvfrom: Function not implemented 64 bytes from 192.168.1.254: seq=3 ttl=128 time=0.486 ms ping: recvfrom: Function not implemented 64 bytes from 192.168.1.254: seq=4 ttl=128 time=0.487 ms ping: recvfrom: Function not implemented 64 bytes from 192.168.1.254: seq=5 ttl=128 time=0.939 ms ping: recvfrom: Function not implemented 64 bytes from 192.168.1.254: seq=6 ttl=128 time=0.971 ms ping: recvfrom: Function not implemented 64 bytes from 192.168.1.254: seq=7 ttl=128 time=0.488 ms ping: recvfrom: Funct^C Signed-off-by: Gabor Juhos <juhosg@openwrt.org> Signed-off-by: Austin Foxley <austinf@cetoncorp.com>
