No single points of failure. + * N-way replication of data across storage nodes + * Fast recovery from node failures + * Automatic rebalancing of data on node addition/removal + * Easy deployment: most FS components are userspace daemons + +Also, + * Flexible snapshots (on any directory) + * Recursive accounting (nested files, directories, bytes) + +In contrast to cluster filesystems like GFS, OCFS2, and GPFS that rely +on symmetric access by all clients to shared block devices, Ceph +separates data and metadata management into independent server +clusters, similar to Lustre. Unlike Lustre, however, metadata and +storage nodes run entirely as user space daemons. Storage nodes +utilize btrfs to store data objects, leveraging its advanced features +(checksumming, metadata replication, etc.). File data is striped +across storage nodes in large chunks to distribute workload and +facilitate high throughputs. When storage nodes fail, data is +re-replicated in a distributed fashion by the storage nodes themselves +(with some minimal coordination from a cluster monitor), making the +system extremely efficient and scalable. + +Metadata servers effectively form a large, consistent, distributed +in-memory cache above the file namespace that is extremely scalable, +dynamically redistributes metadata in response to workload changes, +and can tolerate arbitrary (well, non-Byzantine) node failures. The +metadata server takes a somewhat unconventional approach to metadata +storage to significantly improve performance for common workloads. In +particular, inodes with only a single link are embedded in +directories, allowing entire directories of dentries and inodes to be +loaded into its cache with a single I/O operation. The contents of +extremely large directories can be fragmented and managed by +independent metadata servers, allowing scalable concurrent access. + +The system offers automatic data rebalancing/migration when scaling +from a small cluster of just a few nodes to many hundreds, without +requiring an administrator carve the data set into static volumes or +go through the tedious process of migrating data between servers. +When the file system approaches full, new nodes can be easily added +and things will "just work." + +Ceph includes flexible snapshot mechanism that allows a user to create +a snapshot on any subdirectory (and its nested contents) in the +system. Snapshot creation and deletion are as simple as 'mkdir +.snap/foo' and 'rmdir .snap/foo'. + +Ceph also provides some recursive accounting on directories for nested +files and bytes. That is, a 'getfattr -d foo' on any directory in the +system will reveal the total number of nested regular files and +subdirectories, and a summation of all nested file sizes. This makes +the identification of large disk space consumers relatively quick, as +no 'du' or similar recursive scan of the file system is required. + + +Mount Syntax +============ + +The basic mount syntax is: + + # mount -t ceph monip[:port][,monip2[:port]...]:/[subdir] mnt + +You only need to specify a single monitor, as the client will get the +full list when it connects. (However, if the monitor you specify +happens to be down, the mount won't succeed.) The port can be left +off if the monitor is using the default. So if the monitor is at +1.2.3.4, + + # mount -t ceph 1.2.3.4:/ /mnt/ceph + +is sufficient. If /sbin/mount.ceph is installed, a hostname can be +used instead of an IP address. + + + +Mount Options +============= + + ip=A.B.C.D[:N] + Specify the IP and/or port the client should bind to locally. + There is normally not much reason to do this. If the IP is not + specified, the client's IP address is determined by looking at the + address it's connection to the monitor originates from. + + wsize=X + Specify the maximum write size in bytes. By default there is no + maximu. Ceph will normally size writes based on the file stripe + size. + + rsize=X + Specify the maximum readahead. + + mount_timeout=X + Specify the timeout value for mount (in seconds), in the case + of a non-responsive Ceph file system. The default is 30 + seconds. + + rbytes + When stat() is called on a directory, set st_size to 'rbytes', + the summation of file sizes over all files nested beneath that + directory. This is the default. + + norbytes + When stat() is called on a directory, set st_size to the + number of entries in that directory. + + nocrc + Disable CRC32C calculation for data writes. If set, the OSD + must rely on TCP's error correction to detect data corruption + in the data payload. + + noasyncreaddir + Disable client's use its local cache to satisfy readdir + requests. (This does not change correctness; the client uses + cached metadata only when a lease or capability ensures it is + valid.) + + +More Information +================ + +For more information on Ceph, see the home page at + http://ceph.newdream.net/ + +The Linux kernel client source tree is available at + git://ceph.newdream.net/linux-ceph-client.git + +and the source for the full system is at + git://ceph.newdream.net/ceph.git From 0dee3c28af2fbe22ca62739a7f57da5435d35793 Mon Sep 17 00:00:00 2001 From: Sage Weil Date: Tue, 6 Oct 2009 11:31:06 -0700 Subject: [PATCH 0002/1624] ceph: on-wire types These headers describe the types used to exchange messages between the Ceph client and various servers. All types are little-endian and packed. These headers are shared between the kernel and userspace, so all types are in terms of e.g. __u32. Additionally, we define a few magic values to identify the current version of the protocol(s) in use, so that discrepancies to be detected on mount.

We also include routines to incorporate metadata structures returned by the MDS into the client cache, and some helpers to deal with file capabilities and metadata leases. The bulk of that work is done by fill_inode() and fill_trace().

We take advantage of lookup intents when possible. For the most part, we just need to build the proper requests for the metadata server(s) and pass things off to the mds_client. The results of most operations are normally incorporated into the client's cache when the reply is parsed by ceph_fill_trace(). However, if the MDS replies without a trace (e.g., when retrying an update after an MDS failure recovery), some operation-specific cleanup may be needed. We can validate cached dentries in two ways. A per-dentry lease may be issued by the MDS, or a per-directory cap may be issued that acts as a lease on the entire directory. In the latter case, a 'gen' value is used to determine which dentries belong to the currently leased directory contents. We normally prepopulate the dcache and icache with readdir results. This makes subsequent lookups and getattrs avoid any server interaction. It also lets us satisfy readdir operation by peeking at the dcache IFF we hold the per-directory cap/lease, previously performed a readdir, and haven't dropped any of the resulting dentries.

We take references on held capabilities for the duration of the read/write to avoid prematurely releasing them back to the MDS. We implement two main paths for read and write: one that is buffered (and uses generic_aio_{read,write}), and one that is fully synchronous and blocking (operating either on a __user pointer or, if O_DIRECT, directly on user pages).

A writepage() on a page that is not currently writeable due to snapshot writeback ordering constraints is ignored (it was presumably called from kswapd).

We decide which MDS to submit each request to based on cached information about the current partition of the directory hierarchy across the cluster. A stateful session is opened with each MDS before we submit requests to it, and a mutex is used to control the ordering of messages within each session. An MDS request may generate two responses. The first indicates the operation was a success and returns any result. A second reply is sent when the operation commits to disk. Note that locking on the MDS ensures that the results of updates are visible only to the updating client before the operation commits. Requests are linked to the containing directory so that an fsync will wait for them to commit. If an MDS fails and/or recovers, we resubmit requests as needed. We also reconnect existing capabilities to a recovering MDS to reestablish that shared session state. Old dentry leases are invalidated.

This includes determining where objects are stored in the cluster, and ensuring that requests are retried or redirected in the event of a node failure or data migration. If an OSD does not respond before a timeout expires, keepalive messages are sent across the lossless, ordered communications channel to ensure that any break in the TCP is discovered. If the session does reset, a reconnection is attempted and affected requests are resent (by the message transport layer).

It includes some features that are specifically useful for storage, most notably the ability to map each input onto a set of N devices that are separated across administrator-defined failure domains. CRUSH is used to distribute data across the cluster of Ceph storage nodes.

Each capability consists of a set of bits indicating which operations are allowed. If the client holds a *_SHARED cap, the client has a coherent value that can be safely read from the cached inode. In the case of a *_EXCL (exclusive) or FILE_WR capabilities, the client is allowed to change inode attributes (e.g., file size, mtime), note its dirty state in the ceph_cap, and asynchronously flush that metadata change to the MDS. In the event of a conflicting operation (perhaps by another client), the MDS will revoke the conflicting client capabilities. In order for a client to cache an inode, it must hold a capability with at least one MDS server. When inodes are released, release notifications are batched and periodically sent en masse to the MDS cluster to release server state.

Because snapshots apply to subtrees of the file hierarchy and can be created at any time, there is a fair bit of bookkeeping required to make this work. Portions of the hierarchy that belong to the same set of snapshots are described by a single 'snap realm.' A 'snap context' describes the set of snapshots that exist for a given file or directory.

Besides being a bit ugly, that can also miss caps that are dirty but didn't result in a cap requeue: notably, mark_caps_dirty(). Separate the flushing into a separate helper, and traverse the cap_dirty list. This also brings i_dirty_item in line with i_dirty_caps: we are on the list IFF caps != 0. We carry an inode ref IFF dirty_caps|flushing_caps != 0. Lose the unused return value from __ceph_mark_caps_dirty().

Introduce a recon_gen counter to track reconnections to restarted MDSs and kill dead caps based on that instead. Rename gen to cap_gen while we're at it to make it more clear which is which.

The monitor chooses a protocol and responds with an initial message. Initially implement AUTH_NONE, a dummy protocol that provides no security, but works within the new framework. It generates 'authorizers' that are used when connecting to (mds, osd) services that simply state our entity name and global_id. This is a wire protocol change.

The request may be sent multiple times, to multiple OSDs, if the osdmap changes, which means we can get more than one reply. Only read data into the page vector if the reply is coming from the OSD we last sent the request to. Keep track of which connection is using the vector by taking a reference. If another connection was already using the vector before and a new reply comes in on the right connection, revoke the pages from the other connection.

There's no benefit in us always requesting the state of the fan when performing transitions - we want to do everything we can to ensure that the fan turns on when it should do, not risk hardware damage by believing the hardware when it tells us the fan is already on.

This means it hits non-anonymous but disconnected dentry. (NOTE: d_splice_alias() doesn't clear DCACHE_DISCONNECTED) But, vfat_lookup() has interest to alias if it was non-anonymous.

This removes the need for a seperate array of pointers to clocks. Fix a minor problem of re-initialising the pointers in s3c6400_set_clksrc() as this is also called by the cpufreq code. Move these initialisations to the code that does the registration. Based on Harald Welte's original clock changes patch.

Reduce the size of struct clk by 12 bytes and make defining clocks with common implementation functions easier by moving the set_rate, get_rate, round_rate and set_parent calls into a new structure called 'struct clk_ops' and using that instead. This change does make a few clocks larger as they need their own clk_ops, but this is outweighed by the number of clocks with either no ops or having a common set of ops. Update all the users of this.

Since the spdif clock relies on the audio clock, move the audio clocks into their own arrary. Thanks to Marek Szyprowski for testing and pointing out the four clocks what where missed from the clock list.

The select defaults to 8-bit mode so without config the Ethernet doesn't work. This patch uses the new SROM definitions to set nCS1 to the state found in the Samsung U-Boot port for 6410. It may be more conservative that it needs to be since those settings were marked as for CS8900A also using this chip select. But this change is enough to get the ethernet working when booted with Qi.

This patch modifies s3c24xx_serial_initconsole function to accept multiple platform UART information structures. This is required on platforms that have differences among the instances of UART ports. As an example, the FIFO sizes could be different for each UART instance and hence multiple platform UART information structures would be needed. This patch also modifies the s3c24xx_console_init macro since it wraps the call to the s3c24xx_serial_initconsole function.

This could cause the caps or other cache state to become out of sync. (For instance, aborting dbench and doing rm -r on clients would complain about a non-empty directory because the client didn't realize it's aborted file create request completed.) Even we don't unregister, we still can't process the reply normally because we are no longer holding the caller's locks (like the dir i_mutex). So, mark aborted operations with r_aborted, and in the reply handler, be sure to process all the caps. Do not process the namespace changes, though, since we no longer will hold the dir i_mutex. The dentry lease state can also be ignored as it's more forgiving.

Currently, S5P_TIMER_IRQ is based at the end of VICs. This patch changes the S5P_TIMER_IRQ base from end of VICs to 11 in ISA IRQ space. No of VICs varies between SOCs.

This adds preliminary support for the SH-Mobile G-series. The SH-Mobile G-series is a series of ARM/SH multi-core CPUs that aside from the ARM MPU are primarily composed of existing SH IP blocks. This includes initial support for the SH7367 (SH-Mobile G3) CPU and the G3EVM reference board. Only timer, serial console, and NOR flash are supported at this point. Patches for the interrupt controller, pinmux support, clock framework and runtime pm will be submitted as feature patches on top of this.

Power LED on revision A1 is active low and also requires GPIO 4 to be low to work. Tested on my DNS-323 revision A1. I have set the default trigger to timer as that replicates the behaviour of the original firmware, userspace can change the trigger at the end of the boot process providing a useful indication that booting has completed.

We do not simply use vanilla kerberos because of scalability and performance issues when dealing with a large cluster of nodes providing a single logical service. Auth_x provides mutual authentication of client and server and protects against replay and man in the middle attacks.

The getattr was being done while holding a reference to FILE_RD, which can lead to a deadlock if the MDS is revoking that capability bit and can't process the getattr until it does. We fix this by setting a flag if EOF size validation is needed, and doing the getattr in ceph_aio_read, after the RD cap ref is dropped. If the read needs to be continued, we loop and continue traversing the file.

So some cpp magic is added to minimize code duplication. As obviously these two defines need different names, the name of the old device is #defined to the new one when building for only one of imx21 or imx27.

Volker noticed it was provoked by a long "break" seen on the wire when the RX was not driven during powerdown, we discovered we could kill the serial driver just by forcing RX low extenally for a little while. I saw that the processing for BREAK in the driver gets too excited and clears down all set bits in USR2, including that a character is pending. This stops all further characters getting processed.

To allow this, we used to prevent cap reordering while we were iterating. However, we were not safe from races with removal: removing the 'next' cap would make the next pointer from list_for_each_entry_safe be invalid, and cause a lock up or similar badness. Instead, we keep an iterator pointer in the session pointing to the current cap. As before, we avoid reordering. For removal, if the cap isn't the current cap we are iterating over, we are fine. If it is, we clear cap->ci (to mark the cap as pending removal) but leave it in the session list. In iterate_caps, we can safely finish removal and get the next cap pointer. While we're at it, clean up put_cap to not take a cap reservation context, as it was never used.

(To - avoid a pty deadlock with telnetd.) - -Thu Feb 27 01:53:08 1997 Theodore Ts'o - - * serial.c (change_speed): Add support for the termios flag - CMSPAR, which allows the user to select stick parity. - (i.e, if PARODD is set, the parity bit is always 1; if - PARRODD is not set, then the parity bit is always 0). - -Wed Feb 26 19:03:10 1997 Theodore Ts'o - - * serial.c (cleanup_module): Fix memory leak when using the serial - driver as a module; make sure tmp_buf gets freed! - -Tue Feb 25 11:01:59 1997 Theodore Ts'o - - * serial.c (set_modem_info): Add support for setting and clearing - the OUT1 and OUT2 bits. (For special case UART's, usually - for half-duplex.) - (autoconfig, change_speed): Fix TI 16750 support. - -Sun Feb 16 00:14:43 1997 Theodore Ts'o - - * tty_io.c (release_dev): Add sanity check to make sure there are - no waiters on tty->read_wait or tty->write_wait. - - * serial.c (rs_init): Don't autoconfig a device if the I/O region - is already reserved. - - * serial.c (serial_proc_info): Add support for /proc/serial. - -Thu Feb 13 00:49:10 1997 Theodore Ts'o - - * serial.c (receive_chars): When the UART repotrs an overrun - condition, it does so with a valid character. Changed to - not throw away the valid character, but instead report the - overrun after the valid character. - - * serial.c: Added new #ifdef's for some of the advanced serial - driver features. A minimal driver that only supports COM - 1/2/3/4 without sharing serial interrupts only takes 17k; - the full driver takes 32k. - -Wed Feb 12 14:50:44 1997 Theodore Ts'o - - * vt.c: - * pty.c: - * tty_ioctl.c: - * serial.c: Update routines to use the new 2.1 memory access - routines. - -Wed Dec 4 07:51:52 1996 Theodore Ts'o - - * serial.c (change_speed): Use save_flags(); cli() and - restore_flags() in order to ensure we don't accidentally - turn on interrupts when starting up the port. - (startup): Move the insertion of serial structure into the - IRQ chain earlier into the startup processing. Interrupts - should be off this whole time, but we eventually will want - to reduce this window. - -Thu Nov 21 10:05:22 1996 Theodore Ts'o - - * tty_ioctl.c (tty_wait_until_sent): Always check the driver - wait_until_ready routine, even if there are no characters - in the xmit buffer. (There may be charactes in the device - FIFO.) - (n_tty_ioctl): Add new flag tty->flow_stopped which - indicates whether the tty is stopped due to a request by - the TCXONC ioctl (used by tcflow). If so, don't let an - incoming XOFF character restart the tty. The tty can only - be restarted by another TCXONC request. - - * tty_io.c (start_tty): Don't allow the tty to be restarted if - tty->flow_stopped is true. - - * n_tty.c (n_tty_receive_char): If tty->flow_stopped is true, and - IXANY is set, don't eat a character trying to restart the - tty. - - * serial.c (startup): Remove need for MCR_noint from the - async_struct structure. Only turn on DTR and RTS if the - baud rate is not zero. - (change_speed): More accurately calculate the timeout - value based on the word size. Move responsibility of - hangup when speed becomes B0 to rs_set_termios() - (set_serial_info): When changing the UART type set the - current xmit_fifo_size as well as the permanent - xmit_fifo_size. - (rs_ioctl): Fix TCSBRK (used by tcdrain) and TCSBRKP - ioctls to return EINTR if interrupted by a signal. - (rs_set_termios): If the baud rate changes to or from B0, - this function is now responsible for setting or clearing - DTR and RTS. DTR and RTS are only be changed on the - transition to or from the B0 state. - (rs_close): Wait for the characters to drain based on - info->timeout. At low baud rates (50 bps), it may take a - long time for the FIFO to completely drain out! - (rs_wait_until_sent): Fixed timeout handling. Now - releases control to the scheduler, but checks frequently - enough so that the function is sensitive enough to pass - the timing requirements of the NIST-PCTS. - (block_til_ready): When opening the device, don't turn on - DTR and RTS if the baud rate is B0. - -Thu Nov 14 00:06:09 1996 Theodore Ts'o - - * serial.c (autoconfig): Fix autoconfiguration problems; - info->flags wasn't getting initialized from the state - structure. Put in more paranoid test for the 16750. - -Fri Nov 8 20:19:50 1996 Theodore Ts'o - - * n_tty.c (n_tty_flush_buffer): Only call driver->unthrottle() if - the tty was previous throttled. - (n_tty_set_termios, write_chan): Add changes suggested by - Simon P. Allen to allow hardware cooking. - - * tty_ioctl.c (set_termios): If we get a signal while waiting for - the tty to drain, return -EINTR. - - * serial.c (change_speed): Add support for CREAD, as required by - POSIX. - -Sat Nov 2 20:43:10 1996 Theodore Ts'o - - * serial.c: Wholesale changes. Added support for the Startech - 16650 and 16650V2 chips. (WARNING: the new startech - 16650A may or may not work!) Added support for the - TI16750 (not yet tested). Split async_struct into a - transient part (async_struct) and a permanent part - (serial_state) which contains the configuration - information for the ports. Added new driver routines - wait_until_sent() and send_xchar() to help with POSIX - compliance. Added support for radio clocks which waggle - the carrier detect line (CONFIG_HARD_PPS). - - * tty_ioctl.c (tty_wait_until_sent): Added call to new driver - function tty->driver.wait_until_sent(), which returns when - the tty's device xmit buffers are drained. Needed for - full POSIX compliance. - - (send_prio_char): New function, called by the ioctl's - TCIOFF and TCION; uses the new driver call send_xchar(), - which will send the XON or XOFF character at high priority - (and even if tty output is stopped). - -Wed Jun 5 18:52:04 1996 Theodore Ts'o - - * pty.c (pty_close): When closing a pty, make sure packet mode is - cleared. - -Sun May 26 09:33:52 1996 Theodore Ts'o - - * vesa_blank.c (set_vesa_blanking): Add missing verify_area() call. - - * selection.c (set_selection): Add missing verify_area() call. - - * tty_io.c (tty_ioctl): Add missing verify_area() calls. - - * serial.c (rs_ioctl): Add missing verify_area() calls. - (rs_init): Allow initialization of serial driver - configuration from a module. - - * random.c (extract_entropy): Add missing verify_area call. - Don't limit number of characters returned to - 32,768. Extract entropy is now no longer a inlined - function. - - (random_read): Check return value in case extract_entropy - returns an error. - - (secure_tcp_sequence_number): New function which returns a - secure TCP sequence number. This is needed to prevent some - nasty TCP hijacking attacks. - - (init_std_data): Initialize using gettimeofday() instead of - struct timeval xtime. - - (fast_add_entropy_word, add_entropy_word): Rename the - inline function add_entropy_word() to - fast_add_entropy_word(). Make add_entropy_word() be the - non-inlined function which is used in non-timing critical - places, in order to save space. - - (initialize_benchmark, begin_benchmark, end_benchmark): New - functions defined when RANDOM_BENCHMARK is defined. They - allow us to benchmark the speed of the - add_timer_randomness() call. - - (int_ln, rotate_left): Add two new inline functions with - i386 optimized asm instructions. This speeds up the - critical add_entropy_word() and add_timer_randomness() - functions, which are called from interrupt handlers. - -Tue May 7 22:51:11 1996 - - * random.c (add_timer_randomness): Limit the amount randomness - that we estimate to 12 bits. (An arbitrary amount). - - (extract_entropy): To make it harder to analyze the hash - function, fold the hash function in half using XOR, and - use the folded result as the value to emit to the user. - Also, add timer randomness each pass through the - exact_entropy call, to increase the amount of unknown - values during the extraction process. - - (random_ioctl): Use IOR/IOW definitions to define the - ioctl values used by the /dev/random driver. Allow the - old ioctl values to be used for backwards compatibility - (for a limited amount of time). - -Wed Apr 24 14:02:04 1996 Theodore Ts'o - - * random.c (add_timer_randomness): Use 2nd derivative as well to - better estimate entropy. - - (rand_initialize): Explicitly initialize all the pointers - to NULL. (Clearing pointers using memset isn't portable.) - Initialize the random pool with OS-dependent data. - - (random_write): Add sanity checking to the arguments to - random_write(), so that bad arguments won't cause a kernel - SEGV. - - (random_read): Update the access time of the device inode - when you return data to the user. - - (random_ioctl): Wake up the random_wait channel when there - are only WAIT_INPUT_BITS available. Add more paranoia - checks to make sure entropy_count doesn't go beyond the - bounds of (0, POOLSIZE). Add a few missing verify_area - checks. Add support for the RNDCLEARPOOL ioctl, which - zaps the random pool. - - (add_timer_randomness): Wake up the random_wait - channel only when there are WAIT_INPUT_BITS available. - - (random_select): Allow a random refresh daemon process to - select on /dev/random for writing; wake up the daemon when - there are less than WAIT_OUTPUT_BITS bits of randomness - available. - -Tue Apr 23 22:56:07 1996 - - * tty_io.c (init_dev): Change return code when user attempts to - open master pty which is already open from EAGAIN to EIO, - to match with BSD expectations. EIO is more correct - anyway, since EAGAIN implies that retrying will be - successful --- which it might be.... Eventually!! - - * pty.c (pty_open, pty_close): Fix wait loop so that we don't - busy loop while waiting for the master side to open. - Fix tty opening/closing logic. TTY_SLAVE_CLOSED was - renamed to TTY_OTHER_CLOSED, so that the name is more - descriptive. Also fixed code so that the tty flag - actually works correctly now.... - -Mon Apr 1 10:22:01 1996 - - * serial.c (rs_close): Cleaned up modularization changes. - Remove code which forced line discipline back to N_TTY - this is done in the tty upper layers, and there's no - reason to do it here. (Making this change also - removed the requirement that the serial module access - the internal kernel symbol "ldiscs".) - - * tty_io.c (tty_init): Formally register a tty_driver entry for - /dev/tty (device 4, 0) and /dev/console (device 5, 0). - This guarantees that major device numbers 4 and 5 will be - reserved for the tty subsystem (as they have to be because - of /dev/tty and /dev/console). Removed tty_regdev, as - this interface is no longer necessary. - -Sun Mar 17 20:42:47 GMT 1996 - - * serial.c : modularisation (changes in linux/fs/device.c allow - kerneld to automatically load the serial module). - - * Makefile, Config.in : serial modularisation adds. - - * tty_io.c : tty_init_ctty used by to register "cua" driver just - for the /dev/tty device (5,0). Added tty_regdev. - - * serial.c (shutdown, rs_ioctl) : when port shuts down wakeup processes - waiting on delta_msr_wait. The TIOCMIWAIT ioctl returns EIO - if no change was done since the time of call. - -Sat Mar 16 14:33:13 1996 - - * tty_io.c (disassociate_ctty): If disassociate_ctty is called by - exit, do not perform an implicit vhangup on a pty. - -Fri Feb 9 14:15:47 1996 - - * serial.c (block_til_ready): Fixed another race condition which - happens if a hangup happens during the open. - -Wed Jan 10 10:08:00 1996 - - * serial.c (block_til_ready): Remove race condition which happened - if a hangup condition happened during the setup of the - UART, before rs_open() called block_til_ready(). This - caused the info->count counter to be erroneously - decremented. - - * serial.c (startup, rs_open): Remove race condition that could - cause a memory leak of one page. (Fortunately, both race - conditions were relatively rare in practice.) - -Tue Dec 5 13:21:27 1995 - - * serial.c (check_modem_status, rs_ioctl): Support the new - ioctl()'s TIOCGICOUNT, TIOCMIWAIT. These allow an - application program to wait on a modem serial register - status bit change, and to find out how many changes have - taken place for the MSR bits. - - (rs_write): Eliminate a race condition which is introduced - if it is necessary to wait for the semaphore. - -Sat Nov 4 17:14:45 1995 - - * tty_io.c (tty_init): Move registration of TTY_MAJOR and - TTY_AUX_MAJOR to the end, so that /proc/devices looks - prettier. - - * pty.c (pty_init): Use new major numbers for PTY master and slave - devices. This allow us to have more than 64 pty's. We - register the old pty devices for backwards compatibility. - Note that a system should either be using the old pty - devices or the new pty devices --- in general, it should - try to use both, since they map into the same pty table. - The old pty devices are strictly for backwards compatibility. - -Wed Oct 11 12:45:24 1995 - - * tty_io.c (disassociate_ctty): If disassociate_ctty is called by - exit, perform an implicit vhangup on the tty. - - * pty.c (pty_close): When the master pty is closed, send a hangup - to the slave pty. - (pty_open): Use the flag TTY_SLAVE_CLOSED to test to see - if there are any open slave ptys, instead of using - tty->link->count. The old method got confused if there - were processes that had hung-up file descriptors on the - slave tty. - -Tue May 2 00:53:25 1995 - - * tty_io.c (tty_set_ldisc): Wait until the output buffer is - drained before closing the old line discipline --- needed - in only one case: XON/XOFF processing. - - * n_tty.c (n_tty_close): Don't bother waiting until the output - driver is closed; in general, the line discipline - shouldn't care if the hardware is finished - transmitting before the line discipline terminates. - - * tty_io.c (release_dev): Shutdown the line discipline after - decrementing the tty count variable; but set the - TTY_CLOSING flag so that we know that this tty structure - isn't long for this world. - - * tty_io.c (init_dev): Add sanity code to check to see if - TTY_CLOSING is set on a tty structure; if so, something - bad has happened (probably a line discipline close blocked - when it shouldn't have; so do a kernel printk and then - return an error). - -Wed Apr 26 10:23:44 1995 Theodore Y. Ts'o - - * tty_io.c (release_dev): Try to shutdown the line discipline - *before* decrementing the tty count variable; this removes - a potential race condition which occurs when the line - discipline close blocks, and another process then tries - open the same serial port. - - * serial.c (rs_hangup): When hanging up, flush the output buffer - before shutting down the UART. Otherwise the line - discipline close blocks waiting for the characters to get - flushed, which never happens until the serial port gets reused. - -Wed Apr 12 08:06:16 1995 Theodore Y. Ts'o - - * serial.c (do_serial_hangup, do_softint, check_modem_status, - rs_init): Hangups are now scheduled via a separate tqueue - structure in the async_struct structure, tqueue_hangup. - This task is pushed on to the tq_schedule queue, so that - it is processed synchronously by the scheduler. - -Sat Feb 18 12:13:51 1995 Theodore Y. Ts'o (tytso@rt-11) - - * tty_io.c (disassociate_ctty, tty_open, tty_ioctl): Clear - current->tty_old_pgrp field when a session leader - acquires a controlling tty, and after a session leader - has disassociated from a controlling tty. - -Fri Feb 17 09:34:09 1995 Theodore Y. Ts'o (tytso@rt-11) - - * serial.c (rs_interrupt_single, rs_interrupt, rs_interrupt_multi): - Change the number of passes made from 64 to be 256, - configurable with the #define RS_ISR_PASS_LIMIT. - - * serial.c (rs_init, set_serial_info, get_serial_info, rs_close): - Remove support for closing_wait2. Instead, set - tty->closing and rely on the line discipline to prevent - echo wars. - - * n_tty.c (n_tty_receive_char): IEXTEN does not need to be - enabled in order for IXANY to be active. - - If tty->closing is set, then only process XON and XOFF - characters. - -Sun Feb 12 23:57:48 1995 Theodore Y. Ts'o (tytso@rt-11) - - * serial.c (rs_timer): Change the interrupt poll time from 60 - seconds to 10 seconds, configurable with the #define - RS_STROBE_TIME. - - * serial.c (rs_interrupt_multi, startup, shutdown, rs_ioctl, - set_multiport_struct, get_multiport_struct): Add - provisions for a new type of interrupt service routine, - which better supports multiple serial ports on a single - IRQ. - -Sun Feb 5 19:35:11 1995 Theodore Y. Ts'o (tytso@rt-11) - - * tty_ioctl.c (n_tty_ioctl, set_termios, tty_wait_until_sent): - * serial.c (rs_ioctl, rs_close): - * cyclades.c (cy_ioctl, cy_close): - * n_tty.c (n_tty_close): Rename wait_until_sent to - tty_wait_until_sent, so that it's a better name to export - in ksyms.c. - -Sat Feb 4 23:36:20 1995 Theodore Y. Ts'o (tytso@rt-11) - - * serial.c (rs_close): Added missing check for closing_wait2 being - ASYNC_CLOSING_WAIT_NONE. - -Thu Jan 26 09:02:49 1995 Theodore Y. Ts'o (tytso@rt-11) - - * serial.c (rs_init, set_serial_info, get_serial_info, - rs_close): Support close_wait in the serial driver. - This is helpful for slow devices (like serial - plotters) so that their outputs don't get flushed upon - device close. This has to be configurable because - normally we don't want ports to be hung up for long - periods of time during a close when they are not - connected to a device, or the device is powered off. - - The default is to wait 30 seconds; in the case of a - very slow device, the close_wait timeout should be - lengthened. If it is set to 0, the kernel will wait - forever for all of the data to be transmitted. - -Thu Jan 17 01:17:20 1995 Theodore Y. Ts'o (tytso@rt-11) - - * serial.c (startup, change_speed, rs_init): Add support to detect - the StarTech 16650 chip. Treat it as a 16450 for now, - because of its FIFO bugs. - -Thu Jan 5 21:21:57 1995 - - * serial.c: (receive_char): Added counter to prevent infinite loop - when a PCMCIA serial device is ejected. - -Thu Dec 29 17:53:48 1994 - - * tty_io.c (check_tty_count): New procedure which checks - tty->count to make sure that it matches with the number of - open file descriptors which point at the structure. If - the number doesn't match, it prints a warning message. - -Wed Dec 28 15:41:51 1994 - - * tty_io.c (do_tty_hangup, disassociate_ctty): At hangup time, - save the tty's current foreground process group in the - session leader's task structure. When the session leader - terminates, send a SIGHUP, SIGCONT to that process group. - This is not required by POSIX, but it's not prohibited - either, and it appears to be the least intrusive way - to fix a problem that dialup servers have with - orphaned process groups caused by modem hangups. - -Thu Dec 8 14:52:11 1994 - - * serial.c (rs_ioctl): Don't allow most ioctl's if the serial port - isn't initialized. - - * serial.c (rs_close): Don't clear the IER if the serial port - isn't initialized. - - * serial.c (block_til_ready): Don't try to block on the dialin - port if the serial port isn't initialized. - -Wed Dec 7 10:48:30 1994 Si Park (si@wimpol.demon.co.uk) - * tty_io.c (tty_register_driver): Fix bug when linking onto - the tty_drivers list. We now test that there are elements - already on the list before setting the back link from the - first element to the new driver. - - * tty_io.c (tty_unregister_driver): Fix bug in unlinking the - specified driver from the tty_drivers list. We were not - setting the back link correctly. This used to result in - a dangling back link pointer and cause panics on the next - call to get_tty_driver(). - -Tue Nov 29 10:21:09 1994 Theodore Y. Ts'o (tytso@rt-11) - - * tty_io.c (tty_unregister_driver): Fix bug in - tty_unregister_driver where the pointer to the refcount is - tested, instead of the refcount itself. This caused - tty_unregister_driver to always return EBUSY. - -Sat Nov 26 11:59:24 1994 Theodore Y. Ts'o (tytso@rt-11) - - * tty_io.c (tty_ioctl): Add support for the new ioctl - TIOCTTYGSTRUCT, which allow a kernel debugging program - direct read access to the tty and tty_driver structures. - -Fri Nov 25 17:26:22 1994 Theodore Y. Ts'o (tytso@rt-11) - - * serial.c (rs_set_termios): Don't wake up processes blocked in - open when the CLOCAL flag changes, since a blocking - open only samples the CLOCAL flag once when it blocks, - and doesn't check it again. (n.b. FreeBSD has a - different behavior for blocking opens; it's not clear - whether Linux or FreeBSD's interpretation is correct. - POSIX doesn't give clear guidance on this issue, so - this may change in the future....) - - * serial.c (block_til_ready): Use the correct termios structure to - check the CLOCAL flag. If the cuaXX device is active, - then check the saved termios for the ttySXX device. - Otherwise, use the currently active termios structure. - -Sun Nov 6 21:05:44 1994 Theodore Y. Ts'o (tytso@rt-11) - - * serial.c (change_speed): Add support for direct access of - 57,600 and 115,200 bps. - -Wed Nov 2 10:32:36 1994 Theodore Y. Ts'o (tytso@rt-11) - - * n_tty.c (n_tty_receive_room): Only allow excess characters - through if we are in ICANON mode *and* there are other no - pending lines in the buffer. Otherwise cut and paste over - 4k breaks. - -Sat Oct 29 18:17:34 1994 Theodore Y. Ts'o (tytso@rt-11) - - * serial.c (rs_ioctl, get_lsr_info): Added patch suggested by Arne - Riiber so that user mode programs can tell when the - transmitter shift register is empty. - -Thu Oct 27 23:14:29 1994 Theodore Y. Ts'o (tytso@rt-11) - - * tty_ioctl.c (wait_until_sent): Added debugging printk statements - (under the #ifdef TTY_DEBUG_WAIT_UNTIL_SENT) - - * serial.c (rs_interrupt, rs_interrupt_single, receive_chars, - change_speed, rs_close): rs_close now disables receiver - interrupts when closing the serial port. This allows the - serial port to close quickly when Linux and a modem (or a - mouse) are engaged in an echo war; when closing the serial - port, we now first stop listening to incoming characters, - and *then* wait for the transmit buffer to drain. - - In order to make this change, the info->read_status_mask - is now used to control what bits of the line status - register are looked at in the interrupt routine in all - cases; previously it was only used in receive_chars to - select a few of the status bits. - -Mon Oct 24 23:36:21 1994 Theodore Y. Ts'o (tytso@rt-11) - - * serial.c (rs_close): Add a timeout to the transmitter flush - loop; this is just a sanity check in case we have flaky - (or non-existent-but-configured-by-the-user) hardware. - -Fri Oct 21 09:37:23 1994 Theodore Y. Ts'o (tytso@rt-11) - - * tty_io.c (tty_fasync): When asynchronous I/O is enabled, if the - process or process group has not be specified yet, set it - to be the tty's process group, or if that is not yet set, - to the current process's pid. - -Thu Oct 20 23:17:28 1994 Theodore Y. Ts'o (tytso@rt-11) - - * n_tty.c (n_tty_receive_room): If we are doing input - canonicalization, let as many characters through as - possible, so that the excess characters can be "beeped". - -Tue Oct 18 10:02:43 1994 Theodore Y. Ts'o (tytso@rt-11) - - * serial.c (rs_start): Removed an incorrect '!' that was - preventing transmit interrupts from being re-enabled in - rs_start(). Fortunately in most cases it would be - re-enabled elsewhere, but this still should be fixed - correctly. - -Sun Oct 9 23:46:03 1994 Theodore Y. Ts'o (tytso@rt-11) - - * tty_io.c (do_tty_hangup): If the tty driver flags - TTY_DRIVER_RESET_TERMIOS is set, then reset the termios - settings back to the driver's initial configuration. This - allows the termios settings to be reset even if a process - has hung up file descriptors keeping a pty's termios from - being freed and reset. - - * tty_io.c (release_dev): Fix memory leak. The pty's other - termios structure should also be freed. - - * serial.c (rs_close, shutdown): Change how we wait for the - transmitter to completely drain before shutting down the - serial port. We now do it by scheduling in another - process instead of busy looping with the interrupts turned - on. This may eliminate some race condition problems that - some people seem to be reporting. - -Sun Sep 25 14:18:14 1994 Theodore Y. Ts'o (tytso@rt-11) - - * tty_io.c (release_dev): When freeing a tty make sure that both - the tty and the o_tty (if present) aren't a process's - controlling tty. (Previously, we only checked the tty.) - - * serial.c (change_speed): Only enable the Modem Status - Interrupt for a port if CLOCAL is not set or CRTSCTS - is set. If we're not checking the carrier detect and - CTS line, there's no point in enabling the modem - status interrupt. This will save spurious interrupts - from slowing down systems who have terminals that - don't support either line.

However, kernel identity mappings will have different RWX permissions to the pages mapping to text and to the pages padding (which are freed) the text, rodata sections. Hence kernel identity mappings will be broken to smaller pages. For 64-bit, kernel text and kernel identity mappings are different, so we can enable protection checks that come with CONFIG_DEBUG_RODATA, as well as retain 2MB large page mappings for kernel text. Konrad reported a boot failure with the Linux Xen paravirt guest because of this. In this paravirt guest case, the kernel text mapping and the kernel identity mapping share the same page-table pages. Thus forcing the !RW mapping for some of the kernel mappings also cause the kernel identity mappings to be read-only resulting in the boot failure. Linux Xen paravirt guest also uses 4k mappings and don't use 2M mapping. Fix this issue and retain large page performance advantage for native kernels by not working hard and not enforcing !RW for the kernel text mapping, if the current mapping is already using small page mapping.

Some BIOSes return a negative value for the critical trip point. Especially since Windows 2006... We currently invalidate the whole thermal zone in this case. But it may still be needed for cooling, also without critical trip point. This patch invalidates the critical trip point if no _CRT function is found or if it returns negative values, but does not invalidate the whole thermal zone in this case.

db-78xx0-setup.c already present. The following is done: - Configure MPP Lines for the plateform (see my patch for MPP) This is taken from the stock kernel provided by buffalotech (the vendor) - GigaBit Ethernet - Sata - Uart are initiallized in a different way than on the dev board as we have one core only. - USB The kernel has been running for some days now on my plateform.
