Summary of changes from v2.5.13 to v2.5.14 ============================================ (02/05/01 1.447.68.2) A bunch of fixes. (02/05/02 1.447.68.3) Pmac updates (02/05/03 1.513.1.2) Some more small fixes. (02/05/03 1.513.2.1) [PATCH] 2.5.13: vmalloc link failure The following patch fixes this, and also fixes the similar problem in scsi_debug.c: (02/05/03 1.513.2.2) [PATCH] in_ntoa link failure Nothing serious. Whoever it was that did that global replace missed a spot is all... (02/05/03 1.513.2.3) [PATCH] change_floppy() fix Needed both in 2.4 and 2.5 (02/05/03 1.513.2.4) [PATCH] ufs/super.c D'oh. Missing commas... (02/05/03 1.513.2.5) [PATCH] 2.5.13 IDE 50 - Fix wrong usage of time_after in ide.c. This should cure the drive seek timeout problems some people where expierencing. This was clarified to me by Bartek, who apparently checked whatever the actual code is consistent with the comments in front of it. Thank you Bartlomiej Zolnierkiewicz. I think now that we should have time_past(xxx) in . - Fix hpt34x.c compilation. - Minor improvements in ide-pci and some cleanups in ide-probe.c - Nuke some vastly outdated comments. (02/05/03 1.513.2.6) [PATCH] 2.5.13 IDE 51 - Synchronize with Jens. Applying tons of janitorian stuff to his TCQ code. Making functions static where appropriate and so on... Marking the config entry for it experimental and so on. His changelog: 2.5.13 now has the generic tag support that I wrote included, here's an IDE TCQ that uses that. Changes since the version posted for 2.5.12: Fix the ide_tcq_invalidate_queue() WIN_NOP usage needed to clear the internal queue on errors. It was disabled in the last version due to the ata_request changes, it should work now. Remove Promise tcq disable check, it works just fine on Promise as long as we handle the two-drives-with-tcq case like we currently do. (02/05/03 1.513.2.7) [PATCH] remove PRD_SEGMENTS PRD_SEGMENTS was a leftover from struct ata_request an its per-command sg tables. (02/05/03 1.513.2.8) [PATCH] 2.5.13: remove VALID_PAGE This patch removes VALID_PAGE(), as the test was always too late for discontinous memory configuration. It is replaced with pfn_valid()/ virt_addr_valid(), which are used to test the original input value. Other helper functions: pte_pfn() - extract the page number from a pte pfn_to_page()/page_to_pfn() - convert a page number to/from a page struct (02/05/03 1.513.2.9) [PATCH] replace mk_pte_phys() with pfn_pte() Here is the patch to replace mk_pte_phys() with pfn_pte() and so creates the counterpart to pte_pfn(). (02/05/03 1.517) [PATCH] Bluetooth subsystem sync up This updates 2.5.x Bluetooth subsystem and removes the EXPERIMENTAL status of Bluetooth support. BlueZ Core: New generic HCI connection manager. Complete role switch and link policy support. Security mode 1 and 3 support. L2CAP service level security support. HCI filter support. HCI frame time-stamps. SCO (voice links) support. Improved HCI device unregistration (device destructors). Support for L2CAP signalling frame fragmentation. Improved L2CAP timeout handling. New HCI ioctls for changing ACL and SCO MTU. Killed HCI_MAX_DEV limit. Security fixes. HCI USB driver: Performance improvements. Firmware loading support. Stability fixes. URB and disconnect handling rewrite. HCI UART driver: Support for multiple UART protocols. HCI PCMCIA driver: Support for Nokia Bluetooth PC Cards. Support for Anycom Bluetooth PC/CF Cards. (02/05/04 1.516.1.1) [PATCH] 2.5.13 - i8xx series chipsets patches i810_rng: add support for other i8xx chipsets to the Random Number Generator module. This is being done by adding the detection of the 82801E I/O Controller Hub. (02/05/04 1.516.1.2) [PATCH] 2.5.13 - i8xx series chipsets patches (patch 2) Update of PCI-IDS for the 82801BA(M), 82801CA(M) and 82801E I/O Controller Hub's. (02/05/04 1.516.1.3) [PATCH] 2.5.13 - watchdog patches Merge updates from the 2.4 kernel into watchdog.h . (02/05/04 1.516.1.4) [PATCH] 2.5.13 - i8xx series chipsets patches i810-tco: Merge changes of the 2.4 kernel into the i810-tco module. Changes included are: Support for 82801CA(M) chipset, timer margin needs to be > 3, support for WDIOC_SETTIMEOUT and WDIOC_GETTIMEOUT. (02/05/04 1.522) [PATCH] severe ext3 filesystem corruption warning! Fix silly truncate status update (02/05/04 1.523) [PATCH] Do RPC over TCP reply message delivery in sock->data_ready() xprt.c: Speed up synchronous RPC over TCP calls by having the replies delivered by the IPV4 "bottom half", instead of switching to the rpciod process in order to call recvmsg(). - Remove sock_recvmsg() interface. - Remove rpc_xprt_pending list and rpciod_tcp_dispatcher() interface. - Use the new tcp_read_sock() interface to deliver data directly from within tcp_data_ready(). sched.c: - Remove references to rpciod_tcp_dispatcher. xprt.h: - New set of flags to reflect the TCP record read state. Cheers, Trond (02/05/04 1.524) [PATCH] Fix RPC over TCP 'connect' code xprt.c: Fix the RPC over TCP socket reconnect code. Cheers, Trond (02/05/04 1.525) [PATCH] Fix compile warnings... xprt.c: Merge *_write_space() in order to fix compile warning and save space. Cheers, Trond (02/05/04 1.526) [PATCH] kd.h Andrej Lajovic observes that in kd.h the definitions of K_NUMLOCK and K_CAPSLOCK are interchanged. He is right (and this is the case since 1.1.54; nobody noticed because setleds.c does not use these defines). So, here is the fix. No kernel behaviour is changed. (02/05/04 1.527) [PATCH] IDE PIO mode Fix I found this bug in 2.5.10 first. And caused ext2 FS corruption. We are porting Linux to PC-9801 architecture (made by NEC Japan). It has PIO ONLY IDE I/F. So please check PIO mode too. It was introduced in 2.5.9 and still exists in 2.5.13, and caused superblock corruption for Andries. This fixes it. (02/05/04 1.516.2.1) NTFS: Release 2.0.6 - Major bugfix to make compatible with other kernel changes. - Initialize the mftbmp address space properly now that there are more fields in the struct address_space. This was leading to hangs and oopses on umount since 2.5.12 because of changes to other parts of the kernel. We probably want a kernel generic init_address_space() function... - Drop BKL from ntfs_readdir() after consultation with Al Viro. The only caller of ->readdir() is vfs_readdir() which holds i_sem during the call, and i_sem is sufficient protection against changes in the directory inode (including ->i_size). - Use generic_file_llseek() for directories (as opposed to default_llseek()) as this downs i_sem instead of the BKL which is what we now need for exclusion against ->f_pos changes considering we no longer take the BKL in ntfs_readdir(). (02/05/05 1.516.3.1) mm/memory.c: - Remove always unused variable page from remap_pte_range(). - Fix printk in do_wp_page() so it doesn't print out an uninitialized variable (old_page). Add KERN_ERR log level while at it. (02/05/05 1.530) [PATCH] 2.5.13 IDE 52 Adapted from patch Barłomiej Żołnierkiewicz: - make straight8 a flag in ata_channel instead of byte - don't store tables as code in drive_is_flashcard() and ide_xfer_verbose() - fix init_gendisk() (due to 2.5.13 blksize_size[] change) - compress region requesting/releasing in channel_probe() and ide_unregister() - clean a bit ide_setup_ports() Start of DMA handling tratment. - Fix the parameters to ide_build_dmatable() to be channel and request. Rename it to udma_new_table(). udma will mark arch specific functions later. - Let ide_start_dma() take the request directly as an arguemnt. Rename it to ata_start_dma(). After realizing that the usage of the func argument of it was bogous and that nobody is using rwproc we where able to remove both of them. - Fix ide_destroy_dmatable() to take the channel as argument and rename it to udma_destroy_table(). This function should have possible architecture specific implementation as well at some point in time. - Split up the TCQ UDMA handling stuff in to proper functions. Jens must has been dreaming as he introduced them ;-). (02/05/05 1.531) [PATCH] 2.5.13 IDE 53 - Start splitting the functions for host chip handling in to separate entities. This change is quite sensitive and may cause some trouble but it's for certain worth it anyway, because it should for example provide a much better infrastructure for th handling of different architectures. (02/05/05 1.532) [PATCH] [PATCH 2.5.13 IDE 54 - Finish the changes from patch 53. ide_dma_actaion_t is gone now as well as whole hidden code paths associated with it. I hope I didn't mess too many things up with this, since the sheer size of the changes make them sensitive. (Tested on tree different host chip sets so it shouldn't be too bad...) Just still some minor cleanup remaining to be done in this area. The tags lefts there are intentional. In esp. the ide_dma_on method in cy82c693 looks suspicious. Using udma_enable in ide-cd.c, ide-floppy.c and ide-tape.c is suspicious as well. We have just uncovered it. In the next round we will concentrate on the fixes people did send me last time. (02/05/05 1.533) [PATCH] suppress allocation warnings for radix-tree allocations The recently-added page allocation failure warning generates a lot of noise due to radix-tree node allocation failures. Those messages are not interesting. But I think the warning is otherwise useful - "I got an allocation failure and then it crashed" is better than "it crashed". The patch suppresses the message for ratnode allocation failures. (02/05/05 1.534) [PATCH] radix-tree locking fix __delete_from_swap_cache modifies the radix tree. We need to take the lock for writing. (02/05/05 1.535) [PATCH] Allow truncate to discard unmapped buffers The buffer state "uptodate, dirty, unmapped" is legal. It occurs when a mapped page with attached buffers which is over a hole is dirtied. So discard_buffer() needs to be able to discard those buffers as well; otherwise the page ends up clean, with dirty buffers and is unfreeable. (02/05/05 1.536) [PATCH] decouple swapper_space treatment from other address_spaces swapper_space is different. Its pages are locked during writeout, it uses PAGE_SIZE rather than PAGE_CACHE_SIZE. Converting swap to look more like the other address_spaces is a separate project. This patch fully restores the old swap behaviour. - Don't dirty swapcache page buffers in set_page_dirty(). Fixes a problem where __free_pte() runs set_page_dirty() and then immediately runs ClearPageDirty(). The pages ends up clean, with dirty buffers, and is unfreeable. - Hence, don't mark the page clean if its buffers are clean - swap does not have page/buffers dirty state coherency. (02/05/05 1.537) [PATCH] Allow ext3 pages to be written back by VM pressure When ext3 refiles journalled buffers for writeback, it is better to set the page dirty as well as the buffer. So the page will be written out by VM pressure rather than by kjournald alone. (02/05/05 1.538) [PATCH] Fix SMP race in truncate Closes a small race window: testing PageWriteback() outside the page lock introduces the possibility that page could be redirtied and have writeback started after we've inspected PageWriteback. (02/05/05 1.539) [PATCH] handle concurrent block_write_full_page and set_page_dirty set_page_dirty() runs without the page lock. So __block_write_full_page() needs to be able to cope with the page's buffers being dirtied concurrently, on another CPU. Do this with careful ordering and a test-and-set. (02/05/05 1.540) [PATCH] Fix PG_launder Set PG_launder against pages which are under VM writeback. So page allocators will throttle against them. (02/05/05 1.541) [PATCH] Fix concurrent writepage and readpage Pages under writeback are not locked. So it is possible (and quite legal) for a page to be under readpage() while it is still under writeback. For a partially uptodate page with blocksize < PAGE_CACHE_SIZE. When this happens, the read and write I/O completion handlers get confused over the shared BH_Async usage and the page ends up not getting PG_writeback cleared. Truncate gets stuck in D state. The patch separates the read and write I/O completion state. It also shuffles the buffer fields around. Putting the commonly-accessed b_state at offset zero shrinks the kernel by a few hundred bytes because it can be accessed with indirect addressing, not indirect+indexed. (02/05/05 1.542) [PATCH] Documentation update (02/05/05 1.543) [PATCH] do_mounts.c printk fix D'uh. Linus, 2.5 also needs that one. BTW, folks - whoever had submitted "fixes" replacing /dev/root.old with /old/dev/root.old several lines above that one are welcome to think about the reasons why their patches removed "failed" from boot log. (02/05/05 1.544) [PATCH] remove global_bufferlist_lock This patch addresses Andrew's FIXME in buffer.c and adds a spinlock that can be passed to the buffer list manipulation functions to the reiserfs journal. This obsoletes the cheks for lock beeing NULL in buffer.c and the global_bufferlist_lock. In addition osync_inode_list is changed to use list_for_each_prev as in 2.4 instead of a hand-crafted loop. A little comment to the reiserfs folks: your code would be _sooo_ much easier to understand if you used temporary local variables for often referenced fields.. (02/05/05 1.545) [PATCH] fix config.in syntax errors. - appletalk adds unnessesary additional arguments to bool - net/wan has two comment statements on one line, separated by a + (!), also fixup indentation here. - sound uses a bool where it should use a dep_bool (02/05/05 1.546) [PATCH] architecture-independand si_meminfo Si_meminfo() is basically the same for all architectures (mips is a little different by providing a value for the shared field that is different from the originial intent, I will come back to this later), so it makes to have just one instance of it: (02/05/05 1.547) Fix missed parts in the BH locking patch (02/05/05 1.548) Update kernel version
