2006-12-04[S390] cpu shutdown reworkHeiko Carstens5-180/+58
Let one master cpu kill all other cpus instead of sending an external interrupt to all other cpus so they can kill themselves. Simplifies reipl/shutdown functions a lot. Signed-off-by: Heiko Carstens <heiko.carstens@de.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
2006-12-04[S390] cpcmd <-> __cpcmd calling issuesHeiko Carstens4-24/+24
In case of reipl cpcmd gets called when all other cpus are not running anymore. To prevent deadlocks change __cpcmd so that it doesn't take any locks and call cpcmd or __cpcmd, whatever is correct in the current context.

2006-12-04[S390] Bad kexec control page allocation.Heiko Carstens1-1/+1
KEXEC_CONTROL_MEMORY_LIMIT is an unsigned long value and therefore should be defined as one. Otherwise the kexec control page can be allocated above 2GB which will cause a specification exception on the sam31 instruction in the s390 kexec relocation code.

2006-12-04[S390] Reset infrastructure for re-IPL.Heiko Carstens13-108/+246
In case of re-IPL and diag308 doesn't work we have to reset all devices manually and wait synchronously that each reset finished. This patch adds the necessary infrastucture and the first exploiter of it. Subsystems that need to add a function that needs to be called at re-IPL may register/unregister this function via struct reset_call { struct reset_call *next; void (*fn)(void); }; void register_reset_call(struct reset_call *reset); void unregister_reset_call(struct reset_call *reset); When the registered function get called the context is: - all cpus beside the current one are stopped - all machine checks and interrupts are disabled - prefixing is disabled - a default machine check handler is available for use The registered functions may not take any locks are sleep. For the common I/O layer part of this patch: Introduce a reset_call css_reset that does the following: - clear all subchannels - perform a rchp on all channel paths and wait for the resulting machine checks This replaces the calls to clear_all_subchannels() and cio_reset_channel_paths() for kexec and ccw reipl. reipl_ccw_dev() now uses reipl_find_schid() to determine the subchannel id for a given device id. Also remove cio_reset_channel_paths() and friends since they are not needed anymore.

2006-12-04[S390] extmem unbalanced spin_lock.Heiko Carstens1-2/+3
segment save will exit with a lock held if the passed segment doesn't exist. Any subsequent call to segment_save will lead to a deadlock. Fix this and give up the lock before returning.

2006-12-04[S390] return 'count' for successful execution of dasd_eer_enable.Horst Hummel1-4/+5

2006-12-04[S390] Enhanced handling of failed termination requests.Horst Hummel1-5/+11
In case a request timed out and termination did not work, the console was flooded with retry messages (every 1/10s). Now we use a 5s delay per retry and generate a more precise message. Signed-off-by: Horst Hummel <horst.hummel@de.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
2006-12-04[S390] Use diag instead of ccw reipl.Michael Holzheu1-0/+2
Since the diag 308 reipl method is superior to the ccw method, we should use it whenever it is possible. We can do that, if the user has not specified a new reipl ccw device and the system has been ipled from a ccw device.

2006-12-04[S390] No panic for failed rebootMichael Holzheu1-1/+2
If reboot fails (e.g. because wrong devno has been specified by the user), we should just stop all cpus, but should not trigger a kernel panic. Signed-off-by: Michael Holzheu <holzheu@de.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
2006-12-04[S390] termio <-> termios conversion error handling.Heiko Carstens1-33/+1
Get rid of our own user_termio_to_kernel_termios() and kernel_termios_to_user_termio() macros which didn't check for errors on user space accesses. Instead use the generic functions which handle this properly. In addition the generic version of user_termio_to_kernel_termios() also copies the c_line member which was missing in our variant.

If multiple kernel images are installed on one DASD, the loadparm can be used to select the boot configuration.

2006-12-04[S390] handle incorrect values when writing to dasd sysfs attributes.Horst Hummel1-14/+29
When writing to dasd attributes (e.g. readonly), all values besides '1' are handled like '0'. Other sysfs-attributes like 'online' are checking for '1' and for '0' and do not accept other values. Therefore enhanced checking and error handling in dasd_devmap attribute store functions.

2006-12-04[S390] remove salipl memory detection.Christian Borntraeger1-21/+0
The SALIPL entry point has an needless memory detection routine as we later check the memory size again. The SALIPL code also uses diagnose 0x060 if we are running under VM, but this diagnose is not compatible with the 64 bit addressing mode. The solution is to get rid of this code and rely on the memory detection in the startup code.

2006-12-02[NETFILTER]: nf_conntrack: automatic helper assignment for expectationsPatrick McHardy5-6/+21
Some helpers (namely H.323) manually assign further helpers to expected connections. This is not possible with nf_conntrack anymore since we need to know whether a helper is used at allocation time. Handle the helper assignment centrally, which allows to perform the correct allocation and as a nice side effect eliminates the need for the H.323 helper to fiddle with nf_conntrack_lock. Mid term the allocation scheme really needs to be redesigned since we do both the helper and expectation lookup _twice_ for every new connection.

2006-12-02[NETFILTER]: Kill ip_queue from feature removal schedule.Patrick McHardy1-12/+0
We really can't remove ip_queue. Many users use this, there is no binary compatible interface and even the compat replacement for the originally statically linked library doesn't work.

2006-12-02[NET_SCHED]: policer: restore compatibility with old iproute binariesPatrick McHardy1-4/+22
The tc actions increased the size of struct tc_police, which broke compatibility with old iproute binaries since both the act_police and the old NET_CLS_POLICE code check for an exact size match. Since the new members are not even used, the simple fix is to also accept the size of the old structure. Dumping is not affected since old userspace will receive a bigger structure, which is handled fine.
