* nfsd: handle vfs_getattr errors in acl protocolJ. Bruce Fields2013-02-264-9/+24
| | | | | | | | | | | We're currently ignoring errors from vfs_getattr. The correct thing to do is to do the stat in the main service procedure not in the response encoding.

* fs: Fix possible use-after-free with AIOJan Kara2013-02-221-1/+1
| | | | | | | | | | | | | | | Running AIO is pinning inode in memory using file reference. Once AIO is completed using aio_complete(), file reference is put and inode can be freed from memory. So we have to be sure that calling aio_complete() is the last thing we do with the inode.

* fs: Preserve error code in get_empty_filp(), part 2Anatol Pomozov2013-02-228-22/+19
| | | | | | | | | | | | | | | | | | | | | Allocating a file structure in function get_empty_filp() might fail because of several reasons: - not enough memory for file structures - operation is not allowed - user is over its limit Currently the function returns NULL in all cases and we loose the exact reason of the error. All callers of get_empty_filp() assume that the function can fail with ENFILE only. Return error through pointer. Change all callers to preserve this error code.

| * switch compat_sys_wait4() and compat_sys_waitid() to COMPAT_SYSCALL_DEFINEAl Viro2012-12-261-6/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Strictly speaking, ppc64 needs it for C ABI compliance. Realistically I would be very surprised if e.g. passing 0xffffffff as 'options' argument to waitid() from 32bit task would cause problems, but yes, it puts us into undefined behaviour territory. ppc64 expects int argument to be passed in 64bit register with bits 31..63 containing the same value. SYSCALL_DEFINE on ppc provides a wrapper that normalizes the value passed from userland; so does COMPAT_SYSCALL_DEFINE. Plain declaration of compat_sys_something() with an int argument obviously doesn't. Again, for wait4 and waitid I would be extremely surprised if gcc started to produce code depending on that value having been properly sign-extended - the argument(s) in question end up passed blindly to sys_wait4 and sys_waitid resp. and normalization for native syscalls takes care of their use there. Still, better to use COMPAT_SYSCALL_DEFINE here than worry about nasal daemons... Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Saner transition plan for GENERIC_SIGALTSTACK conversion - instead of adding #define sys_sigaltstack sys_sigaltstack in asm/syscalls.h of architecture if it's pulls asm-generic/syscalls.h, only to have those defines removed once all architectures are converted, make the declaration in said asm-generic/syscalls.h conditional on the lack of GENERIC_SIGALTSTACK. Less messy in intermediate stages that way...

| * Ensure that kernel_init_freeable() is not inlined into non __init codeVineet Gupta2012-12-261-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit d6b2123802d "make sure that we always have a return path from kernel_execve()" reshuffled kernel_init()/init_post() to ensure that kernel_execve() has a caller to return to. It removed __init annotation for kernel_init() and introduced/calls a new routine kernel_init_freeable(). Latter however is inlined by any reasonable compiler (ARC gcc 4.4 in this case), causing slight code bloat.

| | | | | | | | | | | | | | | | | | | | | | | | The ia64 function "thread_matches()" has no users since commit e868a55c2a8c ("[IA64] remove find_thread_for_addr()"). Remove it. This allows us to make ptrace_check_attach() static to kernel/ptrace.c, which is good since we'll need to change the semantics of it and fix up all the callers.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add support for the UART device present in Broadcom TruManage capable NetXtreme chips (ie: 5761m 5762, and 5725). This implementation has a hidden transmit FIFO, so running in single-byte interrupt mode results in too many interrupts. The UART_CAP_HFIFO capability was added to track this. It continues to reload the THR as long as the THRE and TSRE bits are set in the LSR up to a specified limit (1024 is used here).
