* parisc: Use compat layer for msgctl, shmat, shmctl and semtimedop syscallsHelge Deller2014-11-10
| | | | | | | | | | | | | | | | | Switch over the msgctl, shmat, shmctl and semtimedop syscalls to use the compat layer. The problem was found with the debian procenv package, which called shmctl(0, SHM_INFO, &info); in which the shmctl syscall then overwrote parts of the surrounding areas on the stack on which the info variable was stored and thus lead to a segfault later on. Additionally fix the definition of struct shminfo64 to use unsigned longs like the other architectures. This has no impact on userspace since we only have a 32bit userspace up to now.

It went unnoticed so long, because the calling syntax when using a 64bit parameter in a 32bit syscall is quite complex and even worse, it may be even different if you call syscall() or the glibc wrapper. This patch makes the kernel accept the calling convention when called by the glibc wrapper. The other two patches are trivial and remove unused headers, #includes and adds the serial ports of the fastest C8000 workstation to the parisc-kernel internal hardware database" * 'parisc-3.16-5' of git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux: parisc: drop unused defines and header includes parisc: fix fanotify_mark() syscall on 32bit compat kernel parisc: add serial ports of C8000/1GHz machine to hardware database
| * parisc: fix fanotify_mark() syscall on 32bit compat kernelHelge Deller2014-07-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On parisc we can not use the existing compat implementation for fanotify_mark() because for the 64bit mask parameter the higher and lower 32bits are ordered differently than what the compat function expects from big endian architectures. Specifically: It finally turned out, that on hppa we end up with different assignments of parameters to kernel arguments depending on if we call the glibc wrapper function int fanotify_mark (int __fanotify_fd, unsigned int __flags, uint64_t __mask, int __dfd, const char *__pathname); or directly calling the syscall manually syscall(__NR_fanotify_mark, ...) Reason is, that the syscall() function is implemented as C-function and because we now have the sysno as first parameter in front of the other parameters the compiler will unexpectedly add an empty paramenter in front of the u64 value to ensure the correct calling alignment for 64bit values. This means, on hppa you can't simply use syscall() to call the kernel fanotify_mark() function directly, but you have to use the glibc function instead. This patch fixes the kernel in the hppa-arch specifc coding to adjust the parameters in a way as if userspace calls the glibc wrapper function fanotify_mark().

* | parisc: 'renameat2()' doesn't need (or have) a separate compat system callLinus Torvalds2014-05-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The 'renameat2()' system call was incorrectly added as a ENTRY_COMP() in the parisc system call table by commit 18e480aa07f78 ("parisc: add renameat2 syscall"). That causes a link-time error due to there not being any compat version of that system call: arch/parisc/kernel/built-in.o: In function `sys_call_table': (.rodata+0xad0): undefined reference to `compat_sys_renameat2' make: *** [vmlinux] Error 1 Easily fixed by marking the system call as being the same for compat as for native by using ENTRY_SAME() instead of ENTRY_COMP().

Adding it now makes our life much easier with userspace applications (like dietlibc and e2fsprogs) since we then behave like all other platforms too and don't need extra patches which are hard to get upstream anyway because we are not a mainstream architecture.

* ns: Wire up the setns system callEric W. Biederman2011-05-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 32bit and 64bit on x86 are tested and working. The rest I have looked at closely and I can't find any problems. setns is an easy system call to wire up. It just takes two ints so I don't expect any weird architecture porting problems. While doing this I have noticed that we have some architectures that are very slow to get new system calls. cris seems to be the slowest where the last system calls wired up were preadv and pwritev. avr32 is weird in that recvmmsg was wired up but never declared in unistd.h. frv is behind with perf_event_open being the last syscall wired up. On h8300 the last system call wired up was epoll_wait. On m32r the last system call wired up was fallocate. mn10300 has recvmmsg as the last system call wired up. The rest seem to at least have syncfs wired up which was new in the 2.6.39. v2: Most of the architecture support added by Daniel Lezcano <dlezcano@fr.ibm.com> v3: ported to v2.6.36-rc4 by: Eric W.

* perf: Do the big rename: Performance Counters -> Performance EventsIngo Molnar2009-09-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Bye-bye Performance Counters, welcome Performance Events! In the past few months the perfcounters subsystem has grown out its initial role of counting hardware events, and has become (and is becoming) a much broader generic event enumeration, reporting, logging, monitoring, analysis facility. Naming its core object 'perf_counter' and naming the subsystem 'perfcounters' has become more and more of a misnomer. With pending code like hw-breakpoints support the 'counter' name is less and less appropriate. All in one, we've decided to rename the subsystem to 'performance events' and to propagate this rename through all fields, variables and API names. (in an ABI compatible fashion) The word 'event' is also a bit shorter than 'counter' - which makes it slightly more convenient to write/handle as well. Thanks goes to Stephane Eranian who first observed this misnomer and suggested a rename. User-space tooling and ABI compatibility is not affected - this patch should be function-invariant. (Also, defconfigs were not touched to keep the size down.) This patch has been generated via the following script: FILES=$(find * -type f | grep -vE 'oprofile|[^K]config') sed -i \ -e 's/PERF_EVENT_/PERF_RECORD_/g' \ -e 's/PERF_COUNTER/PERF_EVENT/g' \ -e 's/perf_counter/perf_event/g' \ -e 's/nb_counters/nb_events/g' \ -e 's/swcounter/swevent/g' \ -e 's/tpcounter_event/tp_event/g' \ $FILES for N in $(find . -name perf_counter.[ch]); do M=$(echo $N | sed 's/perf_counter/perf_event/g') mv $N $M done FILES=$(find . -name perf_event.*) sed -i \ -e 's/COUNTER_MASK/REG_MASK/g' \ -e 's/COUNTER/EVENT/g' \ -e 's/\<event\>/event_id/g' \ -e 's/counter/event/g' \ -e 's/Counter/Event/g' \ $FILES ... to keep it as correct as possible. This script can also be used by anyone who has pending perfcounters patches - it converts a Linux kernel tree over to the new naming. We tried to time this change to the point in time where the amount of pending patches is the smallest: the end of the merge window. Namespace clashes were fixed up in a preparatory patch - and some stylistic fallout will be fixed up in a subsequent patch. ( NOTE: 'counters' are still the proper terminology when we deal with hardware registers - and these sed scripts are a bit over-eager in renaming them. I've undone some of that, but in case there's something left where 'counter' would be better than 'event' we can undo that on an individual basis instead of touching an otherwise nicely automated patch. ) Suggested-by: Stephane Eranian <eranian@google.com> Acked-by: Peter Zijlstra <a.p.zijlstra@chello.nl> Acked-by: Paul Mackerras <paulus@samba.org> Reviewed-by: Arjan van de Ven <arjan@linux.intel.com> Cc: Mike Galbraith <efault@gmx.de> Cc: Arnaldo Carvalho de Melo <acme@redhat.com> Cc: Frederic Weisbecker <fweisbec@gmail.com> Cc: Steven Rostedt <rostedt@goodmis.org> Cc: Benjamin Herrenschmidt <benh@kernel.crashing.org> Cc: David Howells <dhowells@redhat.com> Cc: Kyle McMartin <kyle@mcmartin.ca> Cc: Martin Schwidefsky <schwidefsky@de.ibm.com> Cc: "David S.
