2008-05-03unified (weak) sys_pipe implementationUlrich Drepper1-17/+0
This replaces the duplicated arch-specific versions of "sys_pipe()" with one unified implementation. This removes almost 250 lines of duplicated code. It's marked __weak, so that *if* an architecture wants to override the default implementation it can do so by simply having its own replacement version, since many architectures use alternate calling conventions for the 'pipe()' system call for legacy reasons (ie traditional UNIX implementations often return the two file descriptors in registers) I still haven't changed the cris version even though Linus says the BKL isn't needed. The arch maintainer can easily do it if there are really no obstacles. Signed-off-by: Ulrich Drepper <[email protected]> Signed-off-by: Linus Torvalds <[email protected]>

2008-02-08aout: suppress A.OUT library support if !CONFIG_ARCH_SUPPORTS_AOUTDavid Howells1-47/+0
Suppress A.OUT library support if CONFIG_ARCH_SUPPORTS_AOUT is not set. Not all architectures support the A.OUT binfmt, so the ELF binfmt should not be permitted to go looking for A.OUT libraries to load in such a case. Not only that, but under such conditions A.OUT core dumps are not produced either. To make this work, this patch also does the following: (1) Makes the existence of the contents of linux/a.out.h contingent on CONFIG_ARCH_SUPPORTS_AOUT. (2) Renames dump_thread() to aout_dump_thread() as it's only called by A.OUT core dumping code. (3) Moves aout_dump_thread() into asm/a.out-core.h and makes it inline. This is then included only where needed. This means that this bit of arch code will be stored in the appropriate A.OUT binfmt module rather than the core kernel. (4) Drops A.OUT support for Blackfin (according to Mike Frysinger it's not needed) and FRV. This patch depends on the previous patch to move STACK_TOP[_MAX] out of asm/a.out.h and into asm/processor.h as they're required whether or not A.OUT format is available.

2008-02-07Introduce flags for reserve_bootmem()Bernhard Walle1-1/+2
This patchset adds a flags variable to reserve_bootmem() and uses the BOOTMEM_EXCLUSIVE flag in crashkernel reservation code to detect collisions between crashkernel area and already used memory. This patch: Change the reserve_bootmem() function to accept a new flag BOOTMEM_EXCLUSIVE. If that flag is set, the function returns with -EBUSY if the memory already has been reserved in the past. This is to avoid conflicts. Because that code runs before SMP initialisation, there's no race condition inside reserve_bootmem_core().

2008-02-05timerfd: new timerfd APIDavide Libenzi1-1/+1
This is the new timerfd API as it is implemented by the following patch: int timerfd_create(int clockid, int flags); int timerfd_settime(int ufd, int flags, const struct itimerspec *utmr, struct itimerspec *otmr); int timerfd_gettime(int ufd, struct itimerspec *otmr); The timerfd_create() API creates an un-programmed timerfd fd. The "clockid" parameter can be either CLOCK_MONOTONIC or CLOCK_REALTIME. The timerfd_settime() API give new settings by the timerfd fd, by optionally retrieving the previous expiration time (in case the "otmr" parameter is not NULL). The time value specified in "utmr" is absolute, if the TFD_TIMER_ABSTIME bit is set in the "flags" parameter. Otherwise it's a relative time. The timerfd_gettime() API returns the next expiration time of the timer, or {0, 0} if the timerfd has not been set yet. Like the previous timerfd API implementation, read(2) and poll(2) are supported (with the same interface). Here's a simple test program I used to exercise the new timerfd APIs: http://www.xmailserver.org/timerfd-test2.c [[email protected]: coding-style cleanups] [[email protected]: fix ia64 build] [[email protected]: fix m68k build] [[email protected]: fix mips build] [[email protected]: fix alpha, arm, blackfin, cris, m68k, s390, sparc and sparc64 builds] [[email protected]: fix s390] [[email protected]: fix powerpc build] [[email protected]: fix sparc64 more] Signed-off-by: Davide Libenzi <[email protected]> Cc: Michael Kerrisk <[email protected]> Cc: Thomas Gleixner <[email protected]> Cc: Davide Libenzi <[email protected]> Cc: Michael Kerrisk <[email protected]> Cc: Martin Schwidefsky <[email protected]> Signed-off-by: Heiko Carstens <[email protected]> Cc: Michael Kerrisk <[email protected]> Cc: Davide Libenzi <[email protected]> Signed-off-by: Andrew Morton <[email protected]> Signed-off-by: Linus Torvalds <[email protected]>

2007-09-10Fix spurious syscall tracing after PTRACE_DETACH + PTRACE_ATTACHRoland McGrath1-1/+0
When PTRACE_SYSCALL was used and then PTRACE_DETACH is used, the TIF_SYSCALL_TRACE flag is left set on the formerly-traced task. This means that when a new tracer comes along and does PTRACE_ATTACH, it's possible he gets a syscall tracing stop even though he's never used PTRACE_SYSCALL. This happens if the task was in the middle of a system call when the second PTRACE_ATTACH was done. The symptom is an unexpected SIGTRAP when the tracer thinks that only SIGSTOP should have been provoked by his ptrace calls so far. A few machines already fixed this in ptrace_disable (i386, ia64, m68k). But all other machines do not, and still have this bug. On x86_64, this constitutes a regression in IA32 compatibility support. Since all machines now use TIF_SYSCALL_TRACE for this, I put the clearing of TIF_SYSCALL_TRACE in the generic ptrace_detach code rather than adding it to every other machine's ptrace_disable.

2007-05-08header cleaning: don't include smp_lock.h when not usedRandy Dunlap1-1/+0
Remove includes of <linux/smp_lock.h> where it is not used/needed. Suggested by Al Viro. Builds cleanly on x86_64, i386, alpha, ia64, powerpc, sparc, sparc64, and arm (all 59 defconfigs).

2007-05-04m68k: Mac II ADB fixesFinn Thain1-0/+10
Fix a crash caused by requests placed in the queue with the completed flag already set. This lead to some ADB_SYNC requests returning early and their request structs being popped off the stack while still queued. Stack corruption ensued or an invalid request callback pointer was invoked or both. Eliminate macii_retransmit() and its buggy implementation of macii_write(). Have macii_queue_poll() fully initialise the request queues. Fix a bug in macii_queue_poll() where the last_req pointer was not being set. This caused some requests to leave the queue before being completed (and would also corrupt the stack under certain conditions). Fix a race in macii_start that could set the state machine to "reading" while current_req was null. No longer send poll commands with the ADBREQ_REPLY flag -- doing that caused the replies to be stored in the request buffer where they were forgotten about. Don't autopoll by continuously sending new Talk commands. Get the controller to do that for us. This reduces the ADB interrupt rate on an idle bus to about 5 per second. Only autopoll the devices that were probed. Explicitly clear the interrupt flag when polling. Use disable_irq rather than local_irq_save when polling. Remove excess local_irq_save/restore pairs. Improve bus timeout and service request detection. Remove unused code (last_reply, adb_dir etc) and unneeded code (prefix_len, first_byte etc). Change TIP and TACK to their correct names on this ADB controller (ST_EVEN and ST_ODD). Add some commentry. Add a generous quantity of sanity checks (BUG_ONs). Let m68k macs use the adb_sync boot param too. Tested on Mac II, Mac IIci, Quadra 650, Quadra 700 etc. Signed-off-by: Finn Thain <[email protected]> Signed-off-by: Geert Uytterhoeven <[email protected]> Signed-off-by: Linus Torvalds <[email protected]>
