From b3c3e7d7d9795df16012d5c60e5f789e7fade311 Mon Sep 17 00:00:00 2001 From: Francois Romieu Date: Mon, 27 Feb 2006 23:11:08 +0100 Subject: via-velocity: fix memory corruption when changing the mtu velocity_rx_refill() only replenishes the descriptor entries which belong to the CPU. It works great in the Rx path but the driver must ensure that all the descriptors are freed before velocity_rx_refill() is used in velocity_change_mtu(). The patch resets the Rx descriptors in velocity_free_rd_ring().

Modify code in fc_remote_port_add() to scan the fc_host_rport_bindings() array for consistent bindings regardless of role-type.

Turns out the deferred slice expiry logic is buggy, so remove that for now. We could be left with an idle queue that would never wake up. So kill that logic, always expire immediately. Also fix a potential timer race condition. Patch looks bigger than it is, because it moves a function.

When booting an opposite byte sex kernel (e.g. an LE kernel from BE RedBoot) the current MTD driver fails to handle the partition table and therefore is unable to generate the correct partition map for the flash. So far as I am aware this problem is ARM specific, because only ARM supports software change of the CPU (memory system) byte sex, however the partition table parsing is in generic MTD code. The patch below has been tested on NSLU2 (an IXP4XX based system) with a patch, 10-ixp4xx-copy-from.patch (submitted to linux-arm-kernel - it's ARM specific) required to make the maps/ixp4xx.c driver work with an LE kernel. Builds of the patched system are in the 'unstable' release of OpenSlug and UcSlugC available from www.nslu2-linux.org. These builds are BE, the archives at www.nslu2-linux.org and www.handhelds.org (see monotone.vanille.de) can be built LE (currently DISTRO targets nslu-ltu.conf for LE thumb uclibc (32 bit kernel) and nslu2-lau.conf, nslu2-lag.conf for LE arm uclibc/glibc) and this patch has been tested extensively will both BE and LE systems on the NSLU2 (including swapping between BE and LE by reflashing from both RedBoot and Linux). The patch recognises that the FIS directory (the partition table) is byte-reversed by examining the partition table size, which is known to be one erase block (this is an assumption made elsewhere in redboot.c). If the size matches the erase block after byte swapping the value then byte-reversal is assumed, if not no further action is taken. The patched code is fail safe; should redboot.c be changed to support a partition table with a modified size field the test will fail and the partition table will be assumed to have the host byte sex. If byte-reversal is detected the patch byte swaps the remainder of the 32 bit fields in the copy of the table; this copy is then used to set up the MTD partition map.

In the old pcmcia-cs config file, this card is listed with the comment "not specific enough". The last entry in the axnet_ids has the same comment. They are disabled, and for good reason as it was originally identified by the MANFID, and that is shared with several cards that use both the pcnet_cs driver and axnet_cs driver. I tried my AMB8110 with pcnet_cs, and found that it works fine, and I cannot find a reason for either, except that the old config file recommended axnet_cs.

Our previous approach called for aggressive flushing of the dcache resulting in several problems (including wierd cwd behavior when running /bin/pwd). This patch dramatically simplifies our handling of this fid management. Fids will not be clunked as promptly, but the new approach is more functionally correct. We now clunk un-open fids only when their dentry ref_count reaches 0 (and d_delete is called). Another simplification is we no longer seek to match fids to the process-id or uid of the action initiator. The uid-matching will need to be revisited when we fix the security model.

Unfortunately, by doing so, they would trigger a bug in their matching algorithm causing them to attach to the wrong bus, thus triggering issues with the i2c core and breaking the thermal driver. This patch fixes the probing issue (so that they will work when a windfarm port is done to these machines) and also prevents for now windfarm to load at all on these machines that still use therm_pm72 to avoid wasting resources.

On logically-partitioned machines the first element of the reg property in the memory node is defined to be the "RMO" region, i.e. the memory that the processor can access in real mode. On other machines the first element has no special meaning, so only take it to be the RMO region on LPAR machines.

Fixes slow response when cifs client is mounted to shares on multiple servers and oplock break occurs (usually due to attempt to multiply open a file). When treeids on mutiple mounted shares match and we find the wrong match first, we searched for the wrong cached files to send oplock break response for which usually meant that no matching file was found and thus the server would have to timeout the notification. Oplock break timeout is about 20 seconds on some servers so this could cause significantly slower performance on file open calls in a few cases (in particular when multiple shares are mounted from multiple servers, tree ids match, and we have a cached file which is later opened multiple times). This was the most important of the bugs that was found and fixed at Connectathon (interoperability testing event) this week.

Gunderson reported: - For some reason, it detects the 9845 as a 9735 -- it appears this is simply related to the ordering in parport_serial_pci_tbl[]. If we move the 9845 up above the 9735, it prints out 9710:9845, but no change in behaviour. (We didn't find out why this was the case; we left it alone since it didn't affect our problem.) - The card has no parallel port (at least no physical ones), yet it reports (via its subsystem ID of 0x0014) one parallel port and four serial ports. The probe for the parallel port fails, and the driver just aborts. Thus, it doesn't find the serial ports. Fix the debugging code to use dev_dbg, but don't bother displaying the PCI ID of the detected board (that's accessible via other means.) Also, arrange for parport_register() to return 0 even if it finds no ports.

Numa_maps can now also support huge pages. Fixes: 1. More compact format. Only display fields if they contain additional information. 2. Always display information for all vmas. The old numa_maps did not display vma with no mapped entries. This was a bit confusing because page migration removes ptes for file backed vmas. After page migration a part of the vmas vanished. 3. Rename maxref to maxmap. This is the maximum mapcount of all the pages in a vma and may be used as an indicator as to how many processes may be using a certain vma. 4. Include the ability to scan over huge page vmas. New items shown: dirty Number of pages in a vma that have either the dirty bit set in the page_struct or in the pte. file= The file backing the pages if any stack Stack area heap Heap area huge Huge page area. The number of pages shows is the number of huge pages not the regular sized pages. swapcache Number of pages with swap references. Must be >0 in order to be shown. active Number of active pages. Only displayed if different from the number of pages mapped. writeback Number of pages under writeback. Only displayed if >0.

However, smaps uses page_count for this, so it will return a false positive for every page that is mapped by just that one process, which is also in pagecache or swapcache. There are false positive situations for anonymous pages not in swapcache as well: - page reclaim, migration - get_user_pages (eg. direct-io, ptrace) Use page_mapcount instead, to count the number of mappings to the page. Use vm_normal_page so that weird things like /dev/mem aren't counted either.

On 64-bit systems with IOMMU, set the dma_mask to 40-bit so that pci_map_xxx() calls will map the DMA address below 40 bits if necessary. On 64-bit systems without IOMMU, set the dma_mask to 64-bit and check for DMA addresses exceeding the limit in tg3_start_xmit(). 5788 only supports 32-bit DMA so need to set the mask appropriately also. Thanks to Chris Elmquist at SGI for reporting and helping to debug the problem on 5714. Thanks to David Miller for explaining the HIGHMEM and DMA stuff.

In other words, the noerror behaviour would apply to the next system call where we had to reschedule or deliver a signal, which is not necessarily the current system call. * 32-bit wasn't doing the call to ptrace_notify in the syscall exit path when the _TIF_SINGLESTEP bit was set. * _TIF_RESTOREALL was in both _TIF_USER_WORK_MASK and _TIF_PERSYSCALL_MASK, which is odd since _TIF_RESTOREALL is only set by system calls. I took it out of _TIF_USER_WORK_MASK. * On 64-bit, _TIF_RESTOREALL wasn't causing the non-volatile registers to be restored (unless perhaps a signal was delivered or the syscall was traced or single-stepped). Thus the non-volatile registers weren't restored on exit from a signal handler. We probably got away with it mostly because signal handlers written in C wouldn't alter the non-volatile registers. * On 32-bit I simplified the code and made it more like 64-bit by making the syscall exit path jump to ret_from_except to handle preemption and signal delivery. * 32-bit was calling do_signal unnecessarily when _TIF_RESTOREALL was set - but I think because of that 32-bit was actually restoring the non-volatile registers on exit from a signal handler. * I changed the order of enabling interrupts and saving the non-volatile registers before calling do_syscall_trace_leave; now we enable interrupts first.

It also adds 4 new mount options: uid/gid=forget and uid/gid=ignore. Without any options the id in core and on disk always match. Giving uid/gid=nnn specifies a default ID to be used in core when the on disk ID is -1. uid/gid=ignore forces the in core ID to allways be used no matter what the on disk ID is. uid/gid=forget forces the on disk ID to always be written out as -1. The use of these options allows you to override ownerships on a disk or disable ownwership information from being written, allowing the media to be used portably between different computers and possibly different users without permissions issues that would require root to correct.

There are two types of controls - number of completed RCU updates invoked in a batch (blimit) and monitoring for high rate of incoming RCUs on a cpu (qhimark, qlowmark). By default, the per-cpu batch limit is set to a small value. If the input RCU rate exceeds the high watermark, we do two things - force quiescent state on all cpus and set the batch limit of the CPU to INTMAX. Setting batch limit to INTMAX forces all finished RCUs to be processed in one shot. If we have more than INTMAX RCUs queued up, then we have bigger problems anyway. Once the incoming queued RCUs fall below the low watermark, the batch limit is set to the default. Signed-off-by: Dipankar Sarma Cc: "Paul E. McKenney" Cc: "David S.

Tested on both x86_64 and powerpc. The way we do file struct accounting is not very suitable for batched freeing. For scalability reasons, file accounting was constructor/destructor based. This meant that nr_files was decremented only when the object was removed from the slab cache. This is susceptible to slab fragmentation. With RCU based file structure, consequent batched freeing and a test program like Serge's, we just speed this up and end up with a very fragmented slab - llm22:~ # cat /proc/sys/fs/file-nr 587730 0 758844 At the same time, I see only a 2000+ objects in filp cache. The following patch I fixes this problem. This patch changes the file counting by removing the filp_count_lock. Instead we use a separate percpu counter, nr_files, for now and all accesses to it are through get_nr_files() api. In the sysctl handler for nr_files, we populate files_stat.nr_files before returning to user. Counting files as an when they are created and destroyed (as opposed to inside slab) allows us to correctly count open files with RCU. Signed-off-by: Dipankar Sarma Cc: "Paul E.

This is because they route it to both and the result is anded together and the CPU ends up processing it twice. This patch changes check_timer to disable the 8254 routing for interrupt 0. I think it would be safe on all chipsets actually (i tested it on a couple and it worked everywhere) and Windows seems to do it in a similar way, but to be conservative this patch only enables this mode on ATI (and adds options to enable/disable too) Ported over from a similar x86-64 change. I reused the ACPI earlyquirk infrastructure for the ATI bridge check, but tweaked it a bit to work even without ACPI. Inspired by a patch from Chuck Ebbert, but redone.
