Now that the raw CSD and CID information are available in mmc_card, there's little point not passing the mmc_card structure into the decode functions themselves. This will be necessary, since there's several different formats of CID decode, and the format appears to depend on data in the CSD. If we are unable to decode the CID or CSD, we can mark the card bad and refuse to bind it to any drivers. Users can then retrieve the raw undecoded CID and CSD from sysfs for debugging purposes.

Ordinarily, this is identical to the value in the local APIC's ID register, because nearly all BIOSes accept the HW assigned value. Our systems, made up of individual building blocks, can't do that. Each node boots as a separate system and is joined together by the BIOS. Thus, the BIOS rewrites the local APIC ID register with a new value. Potomac and Nocona chips have a mechanism by which the BIOS writer can change bits 7:5 to match the assigned cluster ID. Bits 2:0 come from the thread ID. However, bits 4:3 are still those latched at reset. Oops! Summary: Large clustered systems can't use cpuid to derive the sibling information. Fix: Use the local APIC ID. That's the value we use to online the CPUs, so it had better be OK. For non-clustered systems, cpuid == local APIC, so nothing but large boxes should be affected.

This manifests itself in two ways, one worse than the other. In the single-threaded case, it just fails to clear out the timers on exec. POSIX says that exec clears out the timers from timer_create (though not the setitimer ones), so it's wrong that a lingering timer could fire after exec and kill the process with a signal it's not expecting. In the multi-threaded case, it not only leaves lingering timers, but it leaks them entirely when it replaces signal_struct, so they will never be freed by the process exiting after that exec. The new per-user RLIMIT_SIGPENDING actually limits the damage here, because a UID will fill up its quota with leaked timers and then never be able to use timer_create again (that's what my test program does). But if you have many many untrusted UIDs, this leak could be considered a DoS risk.

This means we can set the offset to invalid and keep the IO bitmap of that task, and switch back to a valid offset (without any copying) when switching back to that task. (or do a copy if there is another ioperm task we switch to.) I've attached ioport-cache-2.6.8.1.patch that implements this. When there's a single active ioperm() using task in the system then the context-switch overhead is very low and constant: # ./ioperm-latency default no ioperm: scheduling latency: 2478 cycles turning on port 80 ioperm: scheduling latency: 2499 cycles turning on port 65535 ioperm: scheduling latency: 2481 cycles This single-ioperm-user situation matches 99% of the actual ioperm() usage scenarios and gets rid of any copying whatsoever - without relying on any fault mechanism.

Anton Blanchard got several oops'es from hvc_write() accessing NULL as if it were a pointer to an hvc_struct usually stored in tty->driver_data. So this patch checks tty->driver_data in hvc_write() before it is used. Hopefully once Alan Cox's patch is checked in ldisc writes won't continue to happen after tty closes. Anton Blanchard has tested this patch and is unable to reproduce the oops with it applied. Changelog: drivers/char/hvc_console.c - Added comment to hvc_close() to explain the reason for NULLing tty->driver_data. - Added check to hvc_write() to verify that tty->driver_data is valid (NOT NULL) which would be the case if the write operation was invoked after a tty close was initiated on the tty.

We need this in community kernels for diagnostic and performance tools to use, especially on very large machines. This patch registers a dynamic misc device "sn_hwperf" that supports an ioctl interface for reading/writing memory mapped registers on Altix nodes and routers via the new SAL call. It also creates a read-only procfs file "/proc/sgi_sn/sn_topology" to export NUMA topology and Altix hardware inventory. > What tools are using this? Performance Co-Pilot http://oss.sgi.com/projects/pcp in particular, pmshub, shubstats and linkstat.

Then it switches only supported architecture left (ppc/ppc64/arm) from dereferencing pointers to __raw_{read,write}[bwl]. Third part is fixing sparse complaints: add __iomem here and there, and switch one 1bit bitfield from int to unsigned int. After this there should be no sparse complaints in matroxfb.

Nowhere in POSIX nor anywhere else specifies this field in siginfo_t. When Ulrich and I hashed out the system call interface we wanted, we looked at siginfo_t and decided there was plenty of space to throw in si_rusage. Well, it turns out we didn't check the 64-bit platforms. There struct rusage is ridiculously large (lots of longs for things that are never in a million years going to hit 2^32), and my changes bumped up the size of siginfo_t. Changing that size is more trouble than it's worth. This patch reverts the changes to the siginfo_t structure types, and no longer provides the rusage details in SIGCHLD signal data. Instead, I added a fifth argument to the waitid system call to fill in rusage. waitid is the name of the POSIX function with four arguments. It might make sense to rename the system call `waitsys' to follow SGI's system call with the same arguments, or `wait5' in the mindless tradition. But, feh. I just added the argument to sys_waitid, rather than worrying about changing the name in all the tables (and choosing a new stupid name).

A singly linked list was previously used to do fib_info object lookup for various actions in the routing code. This does not scale very well with many devices and even a moderate number of routes. This was noted by Benjamin Lahaise. To fix all of this we use 3 hash tables, two of which grow dynamically as the number fib_info objects increases while the final one is fixes in size. The statically sized table hashes on device index. This is used for fib_sync_down, fib_sync_up, and ip_fib_check_default. The first dynamically sized table is keyed on protocol, prefsrc, and priority. This is used by fib_create_info() to look for existing fib_info objects matching the new one being constructed. The last dynamically sized table is keyed on the preferred source of the route if it has one specified. This is used by fib_sync_down when a local address disappears. There are still some scalability problems for Bens test case in fib_hash.c and I will try to attack those next. Signed-off-by: David S.

This feature was requested by KDE developers. In KDE most programs are started by forking from a kdeinit program that already has the libraries loaded and some other state. Problem is to give these forked programs the proper name. It already writes the command line in the environment (as seen in ps), but top uses a different field in /proc/pid/status that reports current->comm. And that was always "kdeinit" instead of the real command name. So you ended up with lots of kdeinits in your top listing, which was not very useful. This patch adds a new prctl PR_SET_NAME to allow a program to change its comm field. I considered the potential security issues of a program obscuring itself with this interface, but I don't think it matters much because a program can already obscure itself when the admin uses ps instead of top. In case of a KDE desktop calling everything kdeinit is much more obfuscation than the alternative.

Call it shmem_swaplist; shmem_writepage add inode to swaplist when first swap allocated (usually never); shmem_delete_inode remove inode from the list after truncating (if called before, inode could be re-added to it).

Some might want a tmpfs mount with the improved scalability afforded by omitting shmem superblock accounting; or some might just want to test it in an externally-visible tmpfs mount instance. Adopt the convention that mount option -o nr_blocks=0,nr_inodes=0 means without resource limits, and hence no shmem_sb_info. Not recommended for general use, but no worse than ramfs. Disallow remounting from unlimited to limited (no accounting has been done so far, so no idea whether it's permissible), and from limited to unlimited (because we'd need then to free the sbinfo, and visit each inode to reset its i_blocks to 0: why bother?).

Processes building distinct shmem objects in parallel hit heavy contention on shmem superblock stat_lock. Across 256 cpus an intensive test runs 300 times slower than anonymous. Jack Steiner has observed that all the shmem superblock free_blocks and free_inodes accounting is redundant in the case of the internal mount used for SysV shared memory and for shared writable /dev/zero objects (the cases which most concern them): it specifically declines to limit. Based upon Brent Casavant's SHMEM_NOSBINFO patch, this instead just removes the shmem_sb_info structure from the internal kernel mount, testing where necessary for null sbinfo pointer. shmem_set_size moved within CONFIG_TMPFS, its arg named "sbinfo" as elsewhere. This brings shmem object scalability up to that of anonymous memory, in the case where distinct processes are building (faulting to allocate) distinct objects. It significantly improves parallel building of a shared shmem object (that test runs 14 times faster across 256 cpus), but other issues remain in that case: to be addressed in later patches.

Assuming about 1k of lowmem per inode, we need to lower the default nr_inodes limit on machines with significant highmem. Be conservative, but more generous than in the original patch to Keith: limit to number of lowmem pages, which works out around 200,000 on i386. Easily overridden by giving the nr_inodes= mount option: those who want to sail closer to the rocks should be allowed to do so. Notice how tmpfs dentries cannot be reclaimed in the way that disk-based dentries can: so even hard links need to be costed. They are cheaper than inodes, but easier all round to charge the same. This way, the limit for hard links is equally visible through "df -i": but expect occasional bugreports that tmpfs links are being treated like this. Would have been simpler just to move the free_inodes accounting from shmem_delete_inode to shmem_unlink; but that would lose the charge on unlinked but open files.

This new approach is far from the final word in VSID/context allocation, but it's a noticeable improvement on the old method. Replace the VSID allocation algorithm. The new algorithm first generates a 36-bit "proto-VSID" (with 0xfffffffff reserved). For kernel addresses this is equal to the ESID (address >> 28), for user addresses it is: (context << 15) | (esid & 0x7fff) These are distinguishable from kernel proto-VSIDs because the top bit is clear. Proto-VSIDs with the top two bits equal to 0b10 are reserved for now. The proto-VSIDs are then scrambled into real VSIDs with the multiplicative hash: VSID = (proto-VSID * VSID_MULTIPLIER) % VSID_MODULUS where VSID_MULTIPLIER = 268435399 = 0xFFFFFC7 VSID_MODULUS = 2^36-1 = 0xFFFFFFFFF This scramble is 1:1, because VSID_MULTIPLIER and VSID_MODULUS are co-prime since VSID_MULTIPLIER is prime (the largest 28-bit prime, in fact). This scheme has a number of advantages over the old one: - We now have VSIDs for every kernel address (i.e. everything above 0xC000000000000000), except the very top segment. That simplifies a number of things. - We allow for 15 significant bits of ESID for user addresses with 20 bits of context. i.e. 8T (43 bits) of address space for up to 1M contexts, significantly more than the old method (although we will need changes in the hash path and context allocation to take advantage of this). - Because we use a real multiplicative hash function, we have better and more robust hash scattering with this VSID algorithm (at least based on some initial results). Because the MODULUS is 2^n-1 we can use a trick to compute it efficiently without a divide or extra multiply. This makes the new algorithm barely slower than the old one.

With this in place another nice side effect that is easier to achieve is to get rid of struct sock sk->sk_slab, and instead use sk->sk_prot->slab, saving sizeof(void *) on every struct sock instance, but this unfortunatly has to wait for the conversion of all protocols that use per socket slabcaches to use sk->sk_prot, AF_UNIX is the only one AFAIK, so I'll try to convert it to use sk->sk_prot and then get rid of sk->sk_slab. As for the protocols that don't use per socket slabcaches its just a matter of defaulting to sk_cachep at sk_free time if sk->sk_prot is NULL.

Update IsRouter (NTF_ROUTER) flag approrpriately. Specifically, - we should not update it blindly; if Override Flag is unset and lladdr is differnt, we should NOT. - we should set it when we have received RA. - we should set it when we have received Redirect whose target is off-link.

This is because SUSPECT_CONNECTED can be effective only if OVERRIDE is unset, and used only if RETAIN_STATE is set.
