Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it.

This removes a large table from kernel space and need to maintain it. It appeared that it was ok the implementation chosen requires 16 bytes of readable stack space above the user stack pointer. Turned out a few threading implementations munmap the user stack before the thread exits resulting in errors due to the unreadable stack.

MIPS: scall: Always run the seccomp syscall filters The MIPS syscall handler code used to return -ENOSYS on invalid syscalls. Whilst this is expected, it caused problems for seccomp filters because the said filters never had the change to run since the code returned -ENOSYS before triggering them. This caused problems on the chromium testsuite for filters looking for invalid syscalls. This has now changed and the seccomp filters are always run even if the syscall is invalid. We return -ENOSYS once we return from the seccomp filters. Moreover, similar codepaths have been merged in the process which simplifies somewhat the overall syscall code.

MIPS: scall: Handle seccomp filters which redirect syscalls Commit d218af78492a ("MIPS: scall: Always run the seccomp syscall filters") modified the syscall code to always call the seccomp filters, but missed the case where a filter may redirect the syscall, as revealed by the seccomp_bpf self test. The syscall path now restores the syscall from the stack after the filter rather than saving it locally. Syscall number checking and syscall function table lookup is done after the filter may have run such that redirected syscalls are also checked, and executed. The regular path of syscall number checking and pointer lookup is also made more consistent between ABIs with scall64-64.S being the reference. With this patch in place, the seccomp_bpf self test now passes TRACE_syscall.syscall_redirected and TRACE_syscall.syscall_dropped on all MIPS ABIs.

MIPS: scall: Always run the seccomp syscall filters The MIPS syscall handler code used to return -ENOSYS on invalid syscalls. Whilst this is expected, it caused problems for seccomp filters because the said filters never had the change to run since the code returned -ENOSYS before triggering them. This caused problems on the chromium testsuite for filters looking for invalid syscalls. This has now changed and the seccomp filters are always run even if the syscall is invalid. We return -ENOSYS once we return from the seccomp filters. Moreover, similar codepaths have been merged in the process which simplifies somewhat the overall syscall code.

MIPS: O32: Do not handle require 32 bytes from the stack to be readable. Commit 46e12c07b3b9603c60fc1d421ff18618241cb081 (MIPS: O32 / 32-bit: Always copy 4 stack arguments.) change the O32 syscall handler to always load four arguments from the userspace stack even for syscalls that require fewer or no arguments to be copied. This removes a large table from kernel space and need to maintain it. It appeared that it was ok the implementation chosen requires 16 bytes of readable stack space above the user stack pointer. Turned out a few threading implementations munmap the user stack before the thread exits resulting in errors due to the unreadable stack. We now treat any failed load as a if the loaded value was zero and let the actual syscall deal with the situation. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

MIPS: Fix potential DOS by untrusted user app. On a 64 bit kernel if an o32 syscall was made with a syscall number less than 4000, we would read the function from outside of the bounds of the syscall table. This led to non-deterministic behavior including system crashes. While we were at it we reworked the 32 bit version as well to use fewer instructions. Both 32 and 64 bit versions are use the same code now.

ld t2, sys32_call_table(t1) # syscall routine
MIPS: Fix restart of indirect syscalls When 32-bit MIPS userspace invokes a syscall indirectly via syscall(number, arg1, ..., arg7), the kernel looks up the actual syscall based on the given number, shifts the other arguments to the left, and jumps to the syscall. If the syscall is interrupted by a signal and indicates it needs to be restarted by the kernel (by returning ERESTARTNOINTR for example), the syscall must be called directly, since the number is no longer the first argument, and the other arguments are now staged for a direct call. Before shifting the arguments, store the syscall number in pt_regs->regs[2]. This gets copied temporarily into pt_regs->regs[0] after the syscall returns. If the syscall needs to be restarted, handle_signal()/do_signal() copies the number back to pt_regs->reg[2], which ends up in $v0 once control returns to userspace.

[PATCH] Common compat_sys_sysinfo I noticed that almost all architectures implemented exactly the same sys32_sysinfo... except parisc, where a bug was to be found in handling of the uptime. So let's remove a whole whack of code for fun and profit. Cribbed compat_sys_sysinfo from x86_64's implementation, since I figured it would be the best tested. This patch incorporates Arnd's suggestion of not using set_fs/get_fs, but instead extracting out the common code from sys_sysinfo.

net/compat/wext: send different messages to compat tasks Wireless extensions have the unfortunate problem that events are multicast netlink messages, and are not independent of pointer size. Thus, currently 32-bit tasks on 64-bit platforms cannot properly receive events and fail with all kinds of strange problems, for instance wpa_supplicant never notices disassociations, due to the way the 64-bit event looks (to a 32-bit process), the fact that the address is all zeroes is lost, it thinks instead it is 00:00:00:00:01:00. The same problem existed with the ioctls, until David Miller fixed those some time ago in an heroic effort. A different problem caused by this is that we cannot send the ASSOCREQIE/ASSOCRESPIE events because sending them causes a 32-bit wpa_supplicant on a 64-bit system to overwrite its internal information, which is worse than it not getting the information at all -- so we currently resort to sending a custom string event that it then parses. This, however, has a severe size limitation we are frequently hitting with modern access points; this limitation would can be lifted after this patch by sending the correct binary, not custom, event. A similar problem apparently happens for some other netlink users on x86_64 with 32-bit tasks due to the alignment for 64-bit quantities. In order to fix these problems, I have implemented a way to send compat messages to tasks. When sending an event, we send the non-compat event data together with a compat event data in skb_shinfo(main_skb)->frag_list. Then, when the event is read from the socket, the netlink code makes sure to pass out only the skb that is compatible with the task. This approach was suggested by David Miller, my original approach required always sending two skbs but that had various small problems. To determine whether compat is needed or not, I have used the MSG_CMSG_COMPAT flag, and adjusted the call path for recv and recvfrom to include it, even if those calls do not have a cmsg parameter. I have not solved one small part of the problem, and I don't think it is necessary to: if a 32-bit application uses read() rather than any form of recvmsg() it will still get the wrong (64-bit) event. However, neither do applications actually do this, nor would it be a regression. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: David S. Miller <davem@davemloft.net>

[MIPS] The o32 fstatat syscall behaves differently on 32 and 64 bit kernels While working on a glibc patch to support the fstatat() functions[1], I noticed that the o32 implementation behaves differently on 32-bit and 64-bit kernels; the former provides a stat64 while the latter provides a plain (o32) stat. I think the former is what's intended, as there is no separate fstatat64. It's also what x86 does. I think this is just a case of a compat too far.

perf: Do the big rename: Performance Counters -> Performance Events 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.

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.
