This patch converts the 24*sizeof(long) field, ->private, to a void pointer for use by file_operations entrypoints. A ->dtor() method is added to the kiocb in order to support the release of dynamically allocated structures referred to by ->private. The sole in-tree users of ->private are async network read/write, which are not, in fact, async, and so need not handle preallocated ->private as they would need to if ->ki_retry were ever used. The sole truly async operations are direct IO pread()/pwrite() which do not now use ->ki_retry(). All they would need to do in that case is to check for ->private already being allocated for async kiocbs. This rips 88B off the stack on 32-bit in the common case.

These are selected as a result of the __GFP_DMA and __GFP_HIGHMEM zone modifier flags being passed to the memory allocator as part of the GFP mask. Each node has a set of zone lists, node_zonelists, which defines the list and order of zones to scan for each flag combination. When initialising these lists we iterate over modifier combinations 0 .. MAX_NR_ZONES. However, this is only correct when there are at most ZONES_SHIFT flags. If another flag is introduced zonelists for it would not be initialised. This patch introduces GFP_ZONETYPES (based on GFP_ZONEMASK) as a bound for the number of modifier combinations.

His testing is still in progress, but we believe it comes from a nasty locking deficiency I introduced in 2.6.7's anon_vma_prepare. Andrea's original anon_vma_prepare was fine, it needed no anon_vma lock because it was always linking a freshly allocated structure; but my find_mergeable enhancement let it adopt a neighbouring anon_vma, which of course needs locking against a racing linkage from another mm - which the earlier adjust_vma fix seems to have made more likely. Does anon_vma->lock nest inside or outside page_table_lock? Inside, but that's not obvious without a lock ordering list: instead of listing the order here, update the list in filemap.c; but a separate patch because that's less urgent and more likely to get wrong or provoke controversy. (Could do it with anon_vma lock after dropping page_table_lock, but a long comment explaining why some code is safe suggests it's not.)

(other x86 CPU vendors, Transmeta and VIA announced support as well. Windows support for NX has also been announced by Microsoft, for their next service pack.) The NX feature is also being marketed as 'Enhanced Virus Protection'. This patch makes sure Linux has full support for this hardware feature on x86 too. What does this patch do? The pagetable format of current x86 CPUs does not have an 'execute' bit. This means that even if an application maps a memory area without PROT_EXEC, the CPU will still allow code to be executed in this memory. This property is often abused by exploits when they manage to inject hostile code into this memory, for example via a buffer overflow. The NX feature changes this and adds a 'dont execute' bit to the PAE pagetable format. But since the flag defaults to zero (for compatibility reasons), all pages are executable by default and the kernel has to be taught to make use of this bit. If the NX feature is supported by the CPU then the patched kernel turns on NX and it will enforce userspace executability constraints such as a no-exec stack and no-exec mmap and data areas. This means less chance for stack overflows and buffer-overflows to cause exploits. furthermore, the patch also implements 'NX protection' for kernelspace code: only the kernel code and modules are executable - so even kernel-space overflows are harder (in some cases, impossible) to exploit. Here is how kernel code that tries to execute off the stack is stopped: kernel tried to access NX-protected page - exploit attempt? (uid: 500) Unable to handle kernel paging request at virtual address f78d0f40 printing eip: ... The patch is based on a prototype NX patch written for 2.4 by Intel - special thanks go to Suresh Siddha and Jun Nakajima @ Intel. The existing NX support in the 64-bit x86_64 kernels has been written by Andi Kleen and this patch is modeled after his code. Arjan van de Ven has also provided lots of feedback and he has integrated the patch into the Fedora Core 2 kernel. Test rpms are available for download at: http://redhat.com/~arjanv/2.6/RPMS.kernel/ the kernel-2.6.6-1.411 rpms have the NX patch applied. here's a quickstart to recompile the vanilla kernel from source with the NX patch: http://redhat.com/~mingo/nx-patches/QuickStart-NX.txt update: - make the heap non-executable on PT_GNU_STACK binaries. - make all data mmap()s (and the heap) executable on !PT_GNU_STACK (legacy) binaries. This has no effect on non-NX CPUs, but should be much more compatible on NX CPUs. The only effect it has it has on non-NX CPUs is the extra 'x' bit displayed in /proc/PID/maps.

It also obsoletes CONFIG_SERIAL_8250_HCDP, replacing it with CONFIG_EFI_PCDP (which defaults to Y for ia64). In a nutshell, HCDP tells us "these UARTs are available for use as a console," and it's up to the user to explicitly specify the console device. The kernel can guess in some cases, but not all. The PCDP (aka HCDP v2) tells us what we really want to know, namely, "this UART or VGA device is the console device." (It also has provision for support for new device types.)

And no, it's not the old ->getlink() crap - procfs et.al. are not special-cased there. Here's how it works: * ->follow_link() still does what it used to do - replaces vfsmount/dentry in the nameidata it got from caller. However, it can also leave a pathname to be resolved by caller. * we add an array of char * into nameidata; we always work with nd->saved_names[current->link_count]. nd_set_link() sets it, nd_get_link() returns it. * callers of ->follow_link() (all two of them) check if ->follow_link() had left us something to do. If it had (return value was zero and nd_get_link() is non-NULL), they do __vfs_follow_link() on that name. Then they call a new method (->put_link()) that frees whatever has to be freed, etc. Note that absolute majority of symlinks have "resolve a pathname" as part of their ->follow_link(); they can do something else and some don't do that at all, but having that pathname resolution is very, very common. With that change we allow them to shift pathname resolution part to caller. They don't have to - it's perfectly OK to do all work in ->follow_link(). However, leaving the pathname resolution to caller will a) exclude foo_follow_link() stack frame from the picture b) kill 2 stack frames - all callers are in fs/namei.c and they can use inlined variant of vfs_follow_link(). That reduction of stack use is enough to push the limit on nested symlinks from 5 to 8 (actually, even beyond that, but since 8 is common for other Unices it will do fine). For those who have "pure" ->follow_link() (i.e. "find a string that would be symlink contents and say nd_set_link(nd, string)") we also get a common helper implementing ->readlink() - it just calls ->follow_link() on a dummy nameidata, calls vfs_readlink() on result of nd_get_link() and does ->put_link(). Using (or not using) it is up to filesystem; it's a helper that can be used as a ->readlink() for many filesystems, not a reimplementation of sys_readlink(). However, that's _MANY_ filesystems - practically all of them. Note that we don't put any crap like "if this is a normal symlink, do this; otherwise call ->follow_link() and let it do its magic" into callers - all symlinks are handled the same way. Which was the main problem with getlink proposal back then. That covers almost everything; the only cases left are nfs, ncpfs and cifs. Those will go later - we are backwards compatible, so it's not a problem. First patch: infrastructure - helpers allowing ->follow_link() to leave a pathname to be traversed by caller + corresponding code in callers.

The kernel is trying to zero the backlink on the new stack while running with relocation disabled, which potentially cause it to try to access an address outside of the region allowed in real mode.

The ppc64 memset is basically unchanged from the ppc32 version, and it only does 4-byte stores and doesn't unroll the loop. Here's a memset that performs a bit better. I have been using it for 3 weeks now, and Anton has tested it on a variety of machines, without problems.

To make life more interesting, the 32-bit result gets zero-extended to 64 bits, which makes checking for a -1 return value more complicated than it should be. This patch changes call_prom and rtas_call to return an int, and makes the corresponding changes to use ints for the variables used to hold those return values. While I was doing this I finally got annoyed enough with the strings of prom_print() and prom_print_hex() calls that we do to write a simple prom_printf. I deliberately didn't use snprintf because the execution environment is weird at this point - we aren't running at the address we are linked at just yet - and I didn't want to inflict that on any code outside this file. I also did a prom_debug() macro, which eliminated a few ifdefs. There are also a bunch of other minor cleanups. This patch makes very few algorithmic changes but does get rid of a lot of casts. :) I have been running with this patch for a couple of weeks, and Anton has tested it too.

On x86-64 running a 32-bit task, the 32-bit vsyscall DSO page still has no vma but has its pte allocated in the user mm in the normal fashion. This patch makes it use the generic page-table lookup calls rather than the shortcuts. With this, ptrace on x86-64 can access a 32-bit process's vsyscall page. The behavior on x86 is unchanged.

The driver will now compile again, and you can change to a high resolution text mode with stty. Known defects: doesn't play nice with X, nor fbset. C = Cosmetic change L = Logical change A = API change W = register Writing change (1-CA) fb_info and cirrusfb_info: - mostly cosmetic, but a lot less confusing, and no more nasty casting. It used to be stylish to embed struct fb_info_gen (now struct fb_info) as the first member of struct clgenfb_info (now struct cirrusfb_info), and then you'd cast to the deisred struct. Now we pass the size of our data structure to framebuffer_alloc(), and we make fb_info and cirrusfb_info reference each other with pointers (as in radeonfb). In the old code, there two declarations were common: clgenfb_info *fb_info; clgenfb_info *info; since there's also a 'struct fb_info' now, I found this really confusing, and unified usage as: cirrusfb_info *cinfo; fb_info *info; This accounts for a lot of the search and replace cosmetic upgrade. (2-A) All of the FB knowledge of FB internals is gone in 2.6 (3-LW) revised maxclock numbers (cirrusfb_board_info_rec.maxclock[5]) In my quest to get fbset to work, I borrowed some maxclock data from the X.Org tree for various chipsets. It didn't really seem to help. oh well. (3-LA) upgraded PCI registration Instead of doing PCI walking from the driver, we hand off a pci_device_id table to the PCI subsystem and just get called when it finds a relevant board. (4-L) striking lots of __init and __initdata specifiers I was running into some things not working when I moved the call to init_vgachip() from the driver registration to set_par(). I thought perhaps this was due to some things being marked __init accidentally so I axed said annotations. Turns out it was something else. See 5. (5-LA) delayed chip initialization, nasty double-set_par() pseudo-bug Tony says that the fb drivers shouldn't do any chipset initialization until they get a set_par() call. This way, fb modules can be safely unloaded if no one gets around to using them, and the vga_con -> fbcon hand off is smoother, as fbcon can still grab the back-scroll data from vga_con... In any case, moving the calls to init_vgachip() and fbgen_do_set_var() from driver initialization to set_par() revealed that the cirrus register-writing function needs to be called twice for a mode change to work. I don't understand why. (6-LA) split clgen_decode_var() into the bits that check the var and the bits that actually generate register information (par/regs) to write Adding modedb hooks here might actually fix fbset, i think... (7-LW) No longer write the palette in init_vgachip() nor in set_par(). Someone else (fbcon?) seems to be making its own calls to setcolreg() for us. (8-LW) setcolreg() -- while removing all of the console cruft, I had to try to reconstitute the palette code. I think I got this right, but I could be off -- the penguin boots in the correct colors at least ;-) (9-L) pan_display() - we don't do wrap, silly. that's only on the amiga. (10-L) pan+BLT - to make pan play nicely with copyarea()/fillrect() I had to add a couple of calls to cirrusfb_WaitBLT() to make sure the engine is idle.

Waste of text size. - The debug code relies on __builtin_return_address(0) to keep track of the callers. According to rmk, gcc didn't inline some functions as expected and that resulted in useless debug output. This was probably caused by the large debug-only inline functions. The attached patche removes most inline functions: - the empty on release/huge on debug inline functions were replaced with empty macros on release/normal functions on debug. - spurious inline statements were removed. The code is down to 6 inline functions: three one-liners for struct abstractions, one for a might_sleep_if test and two for the performance critical __cache_alloc / __cache_free functions. Note: If an embedded arch wants to save a few bytes by uninlining __cache_{free,alloc}: The right way to do that is to fold the functions into kmem_cache_xy and then replace kmalloc with kmem_cache_alloc(kmem_find_general_cachep(),).

The physical ordering of pages delivered to the IO subsystem is strongly related to the order in which fragments are subdivided from larger blocks of memory tracked by the page allocator. Consider a single MAX_ORDER block of memory in isolation acted on by a sequence of order 0 allocations in an otherwise empty buddy system. Subdividing the block beginning at the highest addresses will yield all the pages of the block in reverse, and subdividing the block begining at the lowest addresses will yield all the pages of the block in physical address order. Empirical tests demonstrate this ordering is preserved, and that changing the order of subdivision so that the lowest page is split off first resolves the sglist merging difficulties encountered by driver authors at Adaptec and others in James Bottomley's testing. James found that before this patch, there were 40 merges out of about 32K segments. Afterward, there were 24007 merges out of 19513 segments, for a merge rate of about 55%. Merges of 128 segments, the maximum allowed, were observed afterward, where beforehand they never occurred. It also improves dbench on my workstation and works fine there.

This means that for each grace period, there will be - one write access to the rcu_ctrlblk.batch cacheline - lots of read accesses to rcu_ctrlblk.batch (3-10*cpus_online()). Behavior similar to the jiffies cacheline, shouldn't be a problem. - cpus_online()+1 write accesses to rcu_ctrlblk.state, all of them starting with spin_lock(&rcu_ctrlblk.state.mutex). For large enough cpus_online() this will be a problem, but all except two of the spin_lock calls only protect the rcu_cpu_mask bitmap, thus a hierarchical bitmap would allow to split the write accesses to multiple cachelines. Tested on an 8-way with reaim. Unfortunately it probably won't help with Jack Steiner's 'ls' test since in this test only one cpu generates rcu entries.

Jack Steiner tested the first one on a 512p and it resolved the rcu cache line trashing. All were tested on osdl with STP. Step one for reducing cacheline trashing within rcupdate.c: The current code uses the rcu_cpu_mask bitmap both for keeping track of the cpus that haven't gone through a quiescent state and for checking if a cpu should look for quiescent states. The bitmap is frequently changed and the check is done by polling - together this causes cache line trashing. If it's cheaper to access a (mostly) read-only cacheline than a cacheline that is frequently dirtied, then it's possible to reduce the trashing by splitting the rcu_cpu_mask bitmap into two cachelines: The patch adds a generation counter and moves it into a separate cacheline. This allows to removes all accesses to rcu_cpumask (in the read-write cacheline) from rcu_pending and at least 50% of the accesses from rcu_check_quiescent_state. rcu_pending and all but one call per cpu to rcu_check_quiescent_state access the read-only cacheline. Probably not enough for 512p, but it's a start, just for 128 byte more memory use, without slowing down rcu grace periods. Obviously the read-only cacheline is not really read-only: it's written once per grace period to indicate that a new grace period is running. Tests on an 8-way Pentium III with reaim showed some improvement: oprofile hits: Reference: http://khack.osdl.org/stp/293075/ Hits % 23741 0.0994 rcu_pending 19057 0.0798 rcu_check_quiescent_state 6530 0.0273 rcu_check_callbacks Patched: http://khack.osdl.org/stp/293076/ 8291 0.0579 rcu_pending 5475 0.0382 rcu_check_quiescent_state 3604 0.0252 rcu_check_callbacks The total runtime differs between both runs, thus the % number must be compared: Around 50% faster. I've uninlined rcu_pending for the test. Tested with reaim and kernbench. Description: - per-cpu quiescbatch and qs_pending fields introduced: quiescbatch contains the number of the last quiescent period that the cpu has seen and qs_pending is set if the cpu has not yet reported the quiescent state for the current period. With these two fields a cpu can test if it should report a quiescent state without having to look at the frequently written rcu_cpu_mask bitmap. - curbatch split into two fields: rcu_ctrlblk.batch.completed and rcu_ctrlblk.batch.cur. This makes it possible to figure out if a grace period is running (completed != cur) without accessing the rcu_cpu_mask bitmap. - rcu_ctrlblk.maxbatch removed and replaced with a true/false next_pending flag: next_pending=1 means that another grace period should be started immediately after the end of the current period. Previously, this was achieved by maxbatch: curbatch==maxbatch means don't start, curbatch!= maxbatch means start. A flag improves the readability: The only possible values for maxbatch were curbatch and curbatch+1. - rcu_ctrlblk split into two cachelines for better performance. - common code from rcu_offline_cpu and rcu_check_quiescent_state merged into cpu_quiet. - rcu_offline_cpu: replace spin_lock_irq with spin_lock_bh, there are no accesses from irq context (and there are accesses to the spinlock with enabled interrupts from tasklet context). - rcu_restart_cpu introduced, s390 should call it after changing nohz: Theoretically the global batch counter could wrap around and end up at RCU_quiescbatch(cpu). Then the cpu would not look for a quiescent state and rcu would lock up.

Using set_buffer_locked means that it can change the end_io function while the page is in the middle of writeback, and the writeback bit on the page will never get cleared.

On PPC64 machines with Altivec (i.e. machines that use the PPC970 chip, such as the G5 powermac), the altivec floating-point instructions can operate in two modes: one where denormalized inputs or outputs are truncated to zero, and one where they aren't. In the latter mode the processor can take an exception when it encounters denormalized floating-point inputs or outputs rather than dealing with them in hardware. This patch adds code to deal properly with the exception, by emulating the instruction that caused the exception. Previously the kernel just switched the altivec unit into the truncate-to-zero mode, which works but is a bit gross. Fortunately there are only a limited set of altivec instructions which can generate the assist exception, so we don't have to emulate the whole altivec instruction set. Note that Altivec is Motorola's name for the PowerPC vector/SIMD instructions; IBM calls the same thing VMX, and currently only IBM makes 64-bit PowerPC CPU chips. Nevertheless, I have used the term Altivec in the PPC64 code for consistency with the PPC32 code.

This is unfortunatly not correct for a bunch of laptops where the real panel data are only present in the RAM image. This works around this problem by preferring the RAM image on mobility chipsets. This is definitely not the best workaround, we need some arch support for linking the RAM image to the PCI ID (preferrably by having the arch snapshot it during boot, isolating us completely from the details of where this image is in memory).

Other drives, and other SiI controllers, are not affected. The fix for this problem is to avoid such requests, in one of three ways, for the affect drive+controller combos: 1) Limit all writes to 15 sectors 2) Use block layer features to avoid creating requests whose length satisfies the above equation. 3) When a request satisfies the above equation, split the request into two writes, neither of which satisfies the equation. I chose fix #1, the most simple to implement. After discussion with Silicon Image and others regarding the impact of this fix, I have decided to remain with fix #1, and will not be implementing a "better fix". This means that the affected SATA drives will see decreased performance, but set of affected drives is small and will never grow larger. Further, the complexity of implementing solution #2 or solution #3 is rather large. When implementing lba48 'large request' support, I unintentionally broke the fix for these affected drives. Kudos to Ricky Beam for noticing this. This change restores the fix, by adding a flag ATA_DFLAG_LOCK_SECTORS to indicate that the max_sectors value set by the low-level driver should never be changed.

The problem is, since we've never actually logged out of the device and cannot do so in interrupt context, we must be sure to perform the logout before the qla2x00_fabric_login() in the RELOGIN_NEEDED code. 2) Sets the Get Port Database options to ZERO when issuing the call to qla2x00_get_port_database(). This consolidates actuall login handling in the place it should be, in the previous qla2x00_fabric_login() call rather than depending on any 'hidden' behaviour of the firmware. If a device did a LOGO after the login, then any subsequent exachanges will be returned with an 0x29 completion status and the RELOGIN_NEEDED code will handle the login. 3) Finally, if the master and slave state do not indicate a logged-in state from the Get Port Database call, then one cannot depend on the information returned from the firmware -- the firmware typically wipes out the PCB information for a given loopID when logged out. So, return immediately with a failed status.

The driver takes the host_lock (with irqsave) at the entry to the ISR, and releases it at the exit. And inside the ISR there are potentially long busy-waits... Like int ctr = 6000000; /* only try for about a second */ while( --ctr && !((dstate = DC390_read8 (DMA_Status)) & DMA_XFER_DONE) && pSRB->SGToBeXferLen ); The attached patch is attempting to fix those places. Not sure if this is a proper fix though. In my understanding, after looking through the code, the host_lock is used to protect host-specific data and host-registers. The ->queuecommand is already called with it help, so, one just, basically, have to protect other contexts - interrupt, timer,... So, looks mostly right.

This can result in stack corruption. The fix is to kmalloc an array to hold the blocks, making sure to allocate something large enough. There was also a recent optimization to force the allocator to find a free region large enough to hold the entire preallocation size. This was sometimes causing more blocks to be allocated then had been requested, which would also overflow the array. Something more elegant is required here, until then just disable the optimization.

The tda9887 module is basically completely rewritten and understands all the config bits now instead of having just some fixed config presets. Some of these config bits can be changed by insmod options now. The other big change is that both modules allow to use the V4L2 API for inter-module communication (i.e. when bttv/saa7134/... pass through the tuning ioctls to the modules). That allows to specify the TV norm more precisely (not just PAL but PAL-I, PAL-BG, ...), which is needed in some cases to make TV audio work correctly. Using the old v4l1 API is still possible so this shouldn't break any users of these two modules.

The problem is that some IOMMU implementations have a maximum limit to the size of the number of contiguously mappable pages (admittedly, this limit is mostly in the resource management algorithms rather than the IOMMUs themselves). This patch adds this concept to the bio layer via the parameter BIO_VMERGE_MAX_SIZE which architectures can define in asm/io.h (if undefined, we assume it to be infinite, which is current behaviour). While adding this, I noticed several places where bio was making incorrect assumptions about virtual mergeability (none of which was a bug: bio was overestimating rather than underestimating). - The worst offender was bio_add_page(), which seemed never to check for virtual mergeability - I also fixed blk_hw_contig_segments() not to check the QUEUE_CLUSTER flag, and not to check the phys segment boundary. In order to track the hw segment size across bios, I had to introduce two extra bio parameters: bi_hw_front_size and bi_hw_back_size which store the sizes of the front and back hw contiguous segments (and which will be equal if there's only one hw segment).

It is also used by version 2 of the ov511 USB webcam driver, which will be merged in the near future. That will reduce some code duplication, since the existing ov511 has much of this code built-in.

See File Times. This is used by programs that do backups, so that backing a file up does not count as reading it. Only the owner of the file or the superuser may use this bit. It is useful if you want to do something with the file atime (for instance, moving files that have not been accessed in a while to somewhere else, or something like Debian's popularity-contest) but you also want to read all files periodically (for instance, tripwire or debsums). Currently, the program that reads all files periodically has to use utimes, which can race with the atime update: A B open fstat read open read close close utimes And the file still has the old atime, instead of the new one from when B did the read from it. This problem does not happen if A uses O_NOATIME instead of utimes to preserve the atime. This patch adds the O_NOATIME constant for all architectures, but it would also be possible to add it one architecture at a time by defining it to 0 when not defined in asm-*.

It is needed for three reasons: (1) So that the size can be bigger than MAX_ORDER. IBM have done some testing on their big PPC64 systems (64GB of RAM) with linux-2.4 and found that they get better performance if the sizes of the inode cache hash, dentry cache hash, buffer head hash and page cache hash are increased beyond MAX_ORDER (order 11). Now the main allocator can't allocate anything larger than MAX_ORDER, but the bootmem allocator can. In 2.6 it appears that only the inode and dentry hashes remain of those four, but there are other hash tables that could use this service. (2) Changing MAX_ORDER appears to have a number of effects beyond just limiting the maximum size that can be allocated in one go. (3) Should someone want a hash table in which each bucket isn't a power of two in size, memory will be wasted as the chunk of memory allocated will be a power of two in size (to hold a power of two number of buckets). On the other hand, using the bootmem allocator means the allocation will only take up sufficient pages to hold it, rather than the next power of two up. Admittedly, this point doesn't apply to the dentry and inode hashes, but it might to another hash table that might want to use this service. I've coelesced the meat of the inode and dentry allocation routines into one such routine in mm/page_alloc.c that the the respective initialisation functions now call before mem_init() is called. This routine gets it's approximation of memory size by counting up the ZONE_NORMAL and ZONE_DMA pages (and ZONE_HIGHMEM if requested) in all the nodes passed to the main allocator by paging_init() (or wherever the arch does it). It does not use max_low_pfn as that doesn't seem to be available on all archs, and it doesn't use num_physpages since that includes highmem pages not available to the kernel for allocating data structures upon - which may not be appropriate when calculating hash table size. On the off chance that the size of each hash bucket may not be exactly a power of two, the routine will only allocate as many pages as is necessary to ensure that the number of buckets is exactly a power of two, rather than allocating the smallest power-of-two sized chunk of memory that will hold the same array of buckets. The maximum size of any single hash table is given by MAX_SYS_HASH_TABLE_ORDER, as is now defined in linux/mmzone.h.

Charge sigqueue allocation and destruction to the user_struct rather than a global pool. This per user rlimit accounting obsoletes the global queued_signals accouting. The patch as charges the sigqueue struct allocation to the queue that it's pending on (the receiver of the signal). So the owner of the queue is charged for whoever writes to it (much like quota for a 777 file). The patch started out charging the task which allocated the sigqueue struct. In most cases, these are always the same user (permission for sending a signal), so those cases are moot. In the cases where it isn't the same user, it's a privileged user sending a signal to another user. It seems wrong to charge the allocation to the privleged user, when the other user could block receipt as long as it feels. The flipside is, someone else can fill your queue (expectation is that someone else is privileged). I think it's right the way it is. The change to revert is very small.

This is both an issue for small ndelay()s for _all_ values for loops_per_jiffy and for certain {n,u}delay()s for many loops_per_jiffy values. Assuming LPJ = 1501115 udelay(87) results in 130597 loops to be spent. However, 1000 * 130597 / 1501115 is 86.999997 us, so we're actually _rounding down_. 1000 * 130598 / 1501115 is 87.000662841, which would be the technically correct thing to do. Of course, for the TSC case this won't matter as the maths take some time, so the actual delay is 1000 * __udelay(x) / lpj + __OVERHEAD(x) Anybody worried about both the additional overhead and the fact that the overhead takes some time to run should add a check if (unlikely(xloops < OVERHEAD)) return; xloops -= OVERHEAD; to the delay() routines in arch/i386/kernel/timers/*.c and determine what the OVERHEAD is.

The following patches address this issue. Move the multiplication of (loops_per_jiffy * xloops) with HZ into the "mull" asm operation.

AFAIK, they are not Debian nor sparc specific but I'm not subscribed to linux-kernel mailing list and since I'm involved with boot-floppies (mainly for sparc), I think I'm right to report it here. Feel free to forward it upstream (I checked the latest 2.3.46 sources and it seems these bugs are still there). These bugs are not release critical. The latter just not gives the user a chance to overwrite TERM env var at boot time. It could be just inconvenient for serial console boot, and in this case, our busybox' init is already enforcing TERM=vt102. Nevertheless if it could not be fixed before the release, I could even write a workaround in busybox' init (it's just a matter of rewriting getenv()). At last, it does not affect sysvinit package because serial console tty is controlled by a getty process which is reading terminal settings on its command line (take a look in inittab for T0 entries, if any). Ok, here is my modest contribution to kernel hacking. I don't know much about kernel internals but it seems that argument parsing is a bit broken. One trivial patch for command line like "init=/bin/sh console=prom" where console=prom is replaced by lot of spaces in previous call to setup_arch() on sparc, therefore the line parsed by parse_options() is really "init=/bin/sh " and a lot of null args are pushed into argv_init. The other patch is for command line like "TERM=vt100" where both default & user TERM entries are pushed into the env array. Taking a look into /proc/1/environ, it shows up: HOME=/ TERM=linux TERM=vt100 It appears that ash (maybe other shells too) is giving the latter entry but glibc getenv() is giving the former. It is therefore impossible to get entry from the user in a C program like busybox' init (used in Debian boot-floppies). I guess getenv() is not written to support duplicate entries, therefore the kernel should avoid such construct.

The bug is closely related to the 'margin' feature of scrolling, which means that if less than four lines should remain unvisible in the direction we are scrolling to, then we scroll a little bit more just to see those few lines. Kind of two small magnets at the borders of the buffer. This bug was also reported with maybe a less clear description by Stepan Koltsov (cc'ed just for fun) back in 2001 and he got no answer. I found it at http://seclists.org/lists/linux-kernel/2001/Nov/0080.html His patch simply disables margin support and hence everythings becomes okay, but you lose a nice feature. Here's a patch that retains margin support and fixes the bug. Works for me, tested for a week. No guarantee. As I don't fully understand the code (see also my previous mail) I'm not 100% sure that I'm doing the right thing, so I'd prefer if someone would take a closer look at it.

The above code might exhaust memory badly, even before the file creation limit is topped. Also, the allocation was independent from the number of fds pushed into the epoll fd hash. Using an rb-tree ther will be not pre-allocation of the hash, and the size of the memory used will be proportional to the number of fds pushed into the epoll fd.

The main point of this patch is using HAS_MII instead of HAS_NWAY for the definition of the board. All the previous trials since the end of last year used HAS_NWAY which disables the Tx part of the transceiver; using HAS_NWAY was the way all 3Com Cyclone and Tornado chips worked, as they had the transceiver integrated. The ATI solution has an external transceiver and I had to physically see the different chip on the board (the board was provided by ATI) to finally understand that it needs the HAS_MII definition... I'm still waiting for some docs from ATI to clarify if this is the correct way of handling this chip and if there are any differences w.r.t EEPROM handling, but as it appears to work and was also confirmed by other testers, I don't want to keep owners of such boards away from their networks :-) The textual identification was a bit hard to decide; it's called "3c920B-EMB-WNM" in the Windows .INF file that Asus provides for their boards. As this name was already used for PCI ID 9210, I added the paranthesis which specifies where this chip is found. The Scyld driver defines FEATURE_TORNADO to include HAS_NWAY. This board would then probably need to not be defined with FEATURE_TORNADO, but the same as in this patch. I would like to publicly thank Tyson Vickers for both ideas and patience during the last few weeks.

As usual, heavily tested. The mode switching code is even lab-tested by SiS (although 100% written by me). Please apply asap (especially since 64bit systems were not properly supported previously; as mentioned, current X.org/XFree86 needs this update for proper communication with the framebuffer driver on 64bit systems. X crashes on such systems with the old driver).

Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds ChangeSet@1.1722.163.53, 2004-06-18 08:01:34-07:00, paul@serice.net [PATCH] iso9660: fix handling of inodes beyond 4GB This is my fourth attempt to patch the isofs code. It is similar to the last posting except this one implements the NFS get_parent() method which has always been missing. The original problem I set out to addresses is that the current iso9660 file system cannot reach inodes located beyond the 4GB barrier. This is caused by using the inode number as the byte offset of the inode data. Being 32-bits wide, the inode number is unable to reach inode data that does not reside on the first 4GB of the file system. This causes real problems with "growisofs" http://fy.chalmers.se/~appro/linux/DVD+RW/#isofs4gb and my pet project "shunt" http://www.serice.net/shunt/ This patch switches the isofs code from iget() to iget5_locked() which allows extra data to be passed into isofs_read_inode() so that inode data anywhere on the disk can be reached. The inode number scheme was also changed. Continuing to use the byte offset would have resulted in non-unique inodes in many common situations, but because the inode number no longer plays any role in reading the meta-data off the disk, I was free to set the inode number to some unique characteristic of the file. I have chosen to use the block offset which is also 32-bits wide. Lastly, the pre-patch code uses the default export_operations to handle accessing the file system through NFS. The problem with this is that the default NFS operations assume that iget() works which is no longer the case because of the necessity of switching to iget5_locked(). So, I had to implement the NFS operations too. As a bonus, I went ahead and implemented the NFS get_parent() method which has always been missing.

Currently the following version numbers are defined: 0: old format (until 2.6.7) with 16 bit uid/gid 1: extended variant (binary compatible to v0 on M68K) 2: extended variant (binary compatible to v0 on everything except M68K) 3: a new binary incompatible format (64 bytes) 4: new binary incompatible format (128 bytes). layout of its first 64 bytes is the same as for v3. 5: marks second half of new binary incompatible format (128 bytes) (layout is not yet defined) All this is accomplished without breaking binary compatibility. 32 bit uid/gid support is compatible with the patch previously floating around and used e.g. by Red Hat. This patch also introduces a config option for a new, binary incompatible "version 3" format that - is uniform across and properly aligned on all platforms - stores pid and ppid - uses AHZ==100 on all platforms (allows to report longer times) Much of the compatibility glue goes away when v1/v2 support is removed from the kernel. Such a patch is at http://www.physik3.uni-rostock.de/tim/kernel/2.7/acct-cleanup-04.patch and might be applied in the 2.7 timeframe. The new v3 format is source compatible with current GNU acct tools (6.3.5). However, current GNU acct tools can be compiled for only one format. As there is no way to pass the kernel configuration to userspace, with my patch it will still only support the old v2 format. Only if v1/v2 support is removed from the kernel, recompiling GNU acct tools will yield v3 support. A preliminary take at the corresponding work on cross-platform userspace tools (GNU acct package) is at http://www.physik3.uni-rostock.de/tim/kernel/utils/acct/ This version of the package is able to read any of the v0/v2/v3 formats, regardless of byte-order (untested), even within the same file. Cross-platform compatibility with m68k (v1 format) is not yet implemented, but native use on m68k should work (untested). pid and ppid are currently only shown by the dump-acct utility.

It validates the PM-Timer rate against PIT channel 2 and rejects the PM-Timer if its rate is not withing 5% of the expected number. Rationale: The PMTMR timers of certain (older) mainboards are running at invalid rates, often much faster than the rate expected by the PM-Timer code. This causes the system clock to run much too fast. See also http://bugme.osdl.org/show_bug.cgi?id=2375 Possible workarounds are disabling the PM-Timer in the kernel config or disabling the PM-Timer at boot time through the "clock=tsc" parameter. However, we believe it is more user friendly to automatically validate the PM-Timer rate at boot time before using it as the system time source.

The patch is versus BK-recent. I've also included a simple, reliable test case which demonstrates the problem this patch is intended to fix. (Note that BK-recent is not sufficient to address this test case, and waiting on the commiting transaction in ext3_new_block is also not sufficient. Been there, tried that, didn't work. We need to do the full-bore retry from the top level. The ext3_should_retry_alloc() will only wait on the committing transaction if there is an active handle; hence Lustre will probably also need to use ext3_should_retry_alloc() if it wants to reliably avoid this particular problem.) #!/bin/sh # # TEST_DIR=/tmp IMAGE=$TEST_DIR/retry.img MNTPT=$TEST_DIR/retry.mnt TEST_SRC=/usr/projects/e2fsprogs/e2fsprogs/build MKE2FS_OPTS="" IMAGE_SIZE=8192 umount $MNTPT dd if=/dev/zero of=$IMAGE bs=4k count=$IMAGE_SIZE mke2fs -j -F $MKE2FS_OPTS $IMAGE function test_log () { echo $* logger -p local4.notice $* } mkdir -p $MNTPT mount -o loop -t ext3 $IMAGE $MNTPT test_log Retry test: BEGIN for i in `seq 1 3` do test_log "Retry test: Loop $i" echo 2 > /proc/sys/fs/jbd-debug while ! mkdir -p $MNTPT/foo/bar do test_log "Retry test: mkdir failed" sleep 1 done echo 0 > /proc/sys/fs/jbd-debug cp -r $TEST_SRC $MNTPT/foo/bar 2> /dev/null rm -rf $MNTPT/* done umount $MNTPT test_log "Retry test: END" akpm@osdl.org Rework the code to make it a formal JBD API entry point.

I've made some changes and tested with a lot of bounds. I don't have a machine with enough memory to fill it up (it would take ~16GB on a 64-bit machine), but I use the "above" code to simulate a lot of situations. The problems were: * IDR_FULL was not the right value * idr_get_new_above() was not defined in the headers or documented. * idr_alloc() bug-ed if there was a race and not enough memory was allocated. It should have returned NULL. * id will overflow when you go past the end. * There was a "(id >= (1 << (layers*IDR_BITS)))" comparison, but at the top layer it would overflow the id and be zero. * The allocation should return ENOSPC for an "above" value with nothing above it, but it returned EAGAIN.

Which means that most users have to mask it off again, and we only have a 24-bit range. So remove that counter. Also: - Remove the BITS_PER_INT define due to namespace collision risk. - Make MAX_ID_SHIFT 31, so counters have a 0 to 2G-1 range. - Why is MAX_ID_SHIFT using sizeof(int) and not sizeof(long)? If it's for consistency across 32- and 64-bit machines, why not just make it "31"? - Does this still hold true with the counter removed? /* We can only use half the bits in the top level because there are only four possible bits in the top level (5 bits * 4 levels = 25 bits, but you only use 24 bits in the id). */ If not, what needs to change?

You will not be able to find many of the entries. The problem is that the IDR code uses 5-bit chunks of the number and the lower portion used by IDR is 24 bits, so you have one bit that leaks over into the comparisons that should not be there. The solution is to mask off that bit before doing IDR processing. This actually causes the POSIX timer code to crash if you create that many timers. I have included an idr_test.tar.gz file that demonstrates this with and without the fix, in case you need more evidence :). * When the IDR fills up, it returns -1. However, there was no way to check for this condition. This patch adds the ability to check for the idr being full and fixes all the users. It also fixes a problem in fs/super.c where the idr code wasn't checking for -1. * There was a race condition creating POSIX timers. The timer was added to a task struct for another process then the data for the timer was filled out. The other task could use/destroy time timer as soon as it is in the task's queue and the lock is released. This moves settup up the timer data to before the timer is enqueued or (for some data) into the lock. * Change things so that the caller doesn't need to run idr_full() to find out the reason for an idr_get_new() failure. Just return -ENOSPC if the tree was full, or -EAGAIN if the caller needs to re-run idr_pre_get() and try again.

One obvious solution is something like ext2's bitmap groups, which puts file data into different areas of the disk based on which subdirectory they are in. The problem with bitmap groups is that if you've got a group of subdirectories their contents will be spread out all over the disk, leading to lots of seeks during a sequential read. This allocator patch uses the packing locality to determine which bitmap group to allocate from, but when you create a file it looks in the bitmaps to see how 'full' that packing locality already is. If it hasn't been heavily used yet, the packing locality is inherited from the parent directory putting files in new subdirs close to the parent subdir, otherwise it is the inode number of the parent directory putting new files far away from the parent subdir. The end result is fewer bitmap groups for the same working set. For example, one test data set created by 20 procs running in parallel has 6822 subdirs. And with vanilla reiserfs that would mean 6822 packing localities. This patch turns that into 26 packing localities. This makes sequential reads of big directory trees more efficient, but it also makes the btree more efficient in general. Things end up sorted better because groups of subdirs end up with similar keys in the btree, instead of being spread out all over. The bitmap grouping code tries to use the start of each bitmap group for metadata, and offsets the data slightly. The data and metadata are still close together, but not completely intermixed like they are in the default allocator. The end result is that leaf nodes tend to be close to each other, making metadata readahead more effective. The old block allocator had the ability to enforce a minimum allocation size, but did not use it. It now tries to do a pass looking for larger allocation chunks before falling back to the old behaviour of taking any blocks it can find. The patch changes the defaults to: mount -o alloc=skip_busy:dirid_groups:packing_groups You can get back the old behaviour with mount -o alloc=skip_busy mount -o alloc=dirid_groups will turn on the bitmap groups mount -o alloc=packing_groups turns on the packing locality reduction code mount -o alloc=skip_busy:dirid_groups turns on both dirid_groups and skip_busy Finally the patch adds a mount -o alloc=oid_groups, which puts files into bitmap groups based on a hash of their objectid. This would be used for databases or other situations where you have a limited number of very large files.

The way it is done is by calling prepare_binprm, which is where these attributes are calculated, before switching the 'file' field in the bprm from the binary to the interpreter. This feature should be used with care, since the interpreter will have root permissions when running a setuid binary owned by root. Please note - - Only root can register an interpreter with binfmt_misc. The feature is documented and the administrator is advised to handle it with care - The new feature is enabled only with a special flag in the registration string. When this flag is not specified the current behavior of binfmt_misc is kept - This is the only 'right' way for an interpreter to know the correct AT_SECURE value for the interpreted binary From: Chris Wright This patchset looks OK, except for one problem. It installs the fd (which could've been unreadable) without unsharing the ->files. So someone can use this to read unreadable yet executable files. Here's a patch which fixes that up. I added one bit that's commented out because I'm not positive if a final steal_locks() is needed. I did a fair amount of rearranging to simplify the error conditions relative to the fd_install(), and unshare_files(). From: Chris Wright I found that the intel patchset (and mine as well) leaked i_writecount on the original executed file. In addition, I verified that the steal_locks() bit is indeed needed.

In a few words - this is a dynamic translator for IA-32 binaries on IPF platform. Following David Mosberger's advice - we use the binfmt_misc mechanism for the invocation of the translator whenever the user tries to exec an IA-32 binary. The EL is meant to help in the migration path from IA-32 to IPF. From our beta customers we learnt that at first stage - they tend to keep their environment mostly intact, using the legacy IA-32 binaries. Such an environment has, naturally, setuid and non-readable binaries. It will be useless to ask the administrator to change the settings of such an environment - some of them are very complex, and the administrators are reluctant to make any changes in a system that already proved itself to be robust and secure. So, our target with these patches is not to enhance the support for scripts but rather to allow a translator to be integrated into a working environment that is not (and should not be) aware to the fact it's being emulated. As I said before - it is practically hopeless to expect an administrator of such a system to change it so that it will suit the current behavior of binfmt_misc. But, even if we could do that, I'm not sure it would be a good idea - these changes are likely to be less secure than the suggested patches - - In order to execute non-readable binaries the binary will have to be made readable, which is obviously less secure than allowing only a trusted translator to read it - There will be no way for the translator to calculate the accurate AT_SECURE value for the translated process. This might end up with the translated process running in a non-secured mode when it actually needs to be secured. I prepared a patch that solves a couple of problems that interpreters have when invoked via binfmt_misc. currently - 1) such interpreters cannot open non-readable binaries 2) the processes will have their credentials and security attributes calculated according to interpreter permissions and not those of the original binary the proposed patch solves these problems by - 1) opening the binary on behalf of the interpreter and passing its fd instead of the path as argv[1] to the interpreter 2) calling prepare_binprm with the file struct of the binary and not the one of the interpreter The new functionality is enabled by adding a special flag to the registration string. If this flag is not added then old behavior is not changed. A preliminary version of this patch was sent to the list on 9/1/2003 with the title "[PATCH]: non-readable binaries - binfmt_misc 2.6.0-test4". This new version fixes the concerns that were raised by the patch, except of calling unshare_files() before allocating a new fd. this is because this feature did not enter 2.6 yet. Arun Sharma says: We were going through an internal review of this patch: http://marc.theaimsgroup.com/?l=linux-kernel&m=107424598901720&w=2 which is in your tree already. I'm not sure if this line of code got sufficient review. + /* call prepare_binprm before switching to interpreter's file + * so that all security calculation will be done according to + * binary and not interpreter */ + retval = prepare_binprm(bprm); The case that concerns me is: unprivileged interpreter and a privileged binary. One can use binfmt_misc to execute untrusted code (interpreter) with elevated privileges. One could argue that all binfmt_misc interpreters are trusted, because only root can register them. But that's a change from the traditional behavior of binfmt_misc (and binfmt_script). (Update): Arun pointed out that calculating the process credentials according to the binary that needs to be translated is a bit risky, since it requires the administrator to pay extra attention not to register an interpreter which is not intended to run with root credentials. After discussing this issue with him, I would like to propose a modified patch: The old patch did 2 things - 1) open the binary for reading and 2) calculate the credentials according to the binary. I removed the riskier part of changing the credentials calculation, so the revised patch only opens the binary for reading. It also includes few words of warning in the description of the 'open-binary' feature in binfmt_misc.txt, and makes the function entry_status print the flags in use. As for the 'credentials' part of the patch, I will prepare a separate patch for it and send it again to the LKML, describe the problem and ask for people comments.

Russell King points out that on some architectures, with the move from 2.4 mm sweeping to 2.6 rmap, this may be a serious omission: very frequently referenced pages never re-marked young, and the worst choices made for unmapping. So, replace ptep_test_and_clear_young by ptep_clear_flush_young throughout rmap.c. Originally I'd imagined making some kind of TLB gather optimization, but don't see what now: whether worth it rather depends on how common cross-cpu flushes are, and whether global or not. ppc and ppc64 have already found this issue, and worked around it by arranging TLB flush from their ptep_test_and_clear_young: with the aid of pgtable rmap pointers. I'm hoping ptep_clear_flush_young will allow ppc and ppc64 to remove that special code, but won't change them myself. It's worth noting that it is Andrea's anon_vma rmap which makes the vma available for ptep_clear_flush_young in page_referenced_one: anonmm and pte_chains would both need an additional find_vma for that.

In particular we no longer save all of the registers for the common exceptions - system calls, hardware interrupts and decrementer (timer) interrupts - only the volatile registers. The other registers are saved and restored (if used) by the C functions we call. This involved changing the registers we use in early exception processing from r20-r23 to r9-r12, which ended up changing quite a lot of code in head.S. Overall this gives us about a 20% reduction in null syscall time. Some system calls need all the registers (e.g. fork/clone/vfork and [rt_]sigsuspend). For these the syscall dispatch code calls a stub that saves the nonvolatile registers before calling the real handler. This also implements the force_successful_syscall_return() thing for ppc64.

That message indicates which ports have events pending (and whether the hub itself has events pending). By only polling the status of the ports listed in the bit-array we can save a fair amount of overhead in hub communication. (The #error test added to hub.h is a little awkward, but it's purely precautionary -- it won't matter until someone decides to support hubs with more than 31 ports!) Also included in the patch, since this seemed the perfect opportunity for it, is Byron's suggestion for handling hub events in the order in which they were received.

I've changed it slightly by moving the input/output assignment into dst_ifdown. To recap, this patch drops lingering IPsec references to a device that is being unregistered. The child processing in the GC is too late since it never runs until the reference on the dst hits zero which could take a long time for things like TCP connections. The reason I've left the input/output assignment outside the loop is because they aren't really necessary for the IPsec dst's, and if it were in the loop then we'll have to do the same child processing in ___dst_free as well. I've tested this with an ESP/IPCOMP tunnel and I can confirm that it does fix the problem. Signed-off-by: Herbert Xu Signed-off-by: David S.
